The President of the Republic of Poland as a Political Arbiter – Competences and the Practice of Their Exercise

Streszczenie

Praca podejmuje problem roli ustrojowej Prezydenta Rzeczypospolitej Polskiej jako arbitra politycznego w świetle Konstytucji z 1997 roku oraz praktyki pięciu prezydentur w latach 1990–2025. Celem opracowania jest ustalenie, czy konstrukcja konstytucyjna polskiej prezydentury odpowiada modelowi pouvoir neutre w ujęciu Benjamina Constanta oraz czy praktyka sprawowania urzędu potwierdza, modyfikuje, czy zaprzecza temu modelowi. W warstwie teoretycznej odwołano się do dorobku polskiej doktryny konstytucyjnej, w szczególności do prac Leszka Garlickiego i Piotra Winczorka, a także do komparatystycznej typologii systemów egzekutywy. Analizie poddano kompetencje prerogatywne Prezydenta (art. 144 ust. 3 Konstytucji), mechanizm weta ustawodawczego oraz uprawnienia w zakresie polityki zagranicznej, bezpieczeństwa narodowego i powoływania organów konstytucyjnych. Część empiryczna obejmuje studium pięciu prezydentur: ekspansjonistycznej prezydentury Wałęsy, prezydentur Kwaśniewskiego jako zbliżonej do modelu arbitrażu, spornej prezydentur Kaczyńskiego i wstrzemięźliwej Komorowskiego oraz prezydentur Dudy, w której najwyraźniej ujawniły się napięcia ustrojowe, w tym kryzys Trybunału Konstytucyjnego w 2015 roku. Wykazano, że Konstytucja z 1997 roku powołała prezydenturę konstytucyjnie zaprojektowaną do pełnienia funkcji arbitrażowej, lecz pozbawioną instrumentów wymuszenia neutralności, co sprawia, że realizacja modelu arbitra pozostaje wyłącznie kwestią indywidualnej woli politycznej osoby sprawującej urząd.

Abstract

This dissertation examines the institutional role of the President of the Republic of Poland as a political arbiter in the light of the Constitution of 1997 and the practice of five presidencies spanning the years 1990 to 2025. The aim of the study is to determine whether the constitutional design of the Polish presidency corresponds to the model of pouvoir neutre as conceived by Benjamin Constant, and whether the actual exercise of the office confirms, modifies, or contradicts that model.^{[10, s. 477]} The theoretical framework draws on the scholarship of Polish constitutional doctrine, with particular reference to the works of Leszek Garlicki and Piotr Winczorek, as well as on comparative typologies of executive systems. An analysis is conducted of the President's prerogative powers under Article 144(3) of the Constitution, the legislative veto mechanism, and competences relating to foreign policy, national security, and the appointment of constitutional bodies. The empirical part comprises a case study of five presidencies: the expansionist presidency of Wałęsa, the presidency of Kwaśniewski as most closely approximating the arbiter model — especially during cohabitation — the contested tenure of Kaczyński, the restrained presidency of Komorowski, and the presidency of Duda, during which constitutional tensions were most acutely manifested, including the Constitutional Tribunal crisis of 2015. It is argued that the Constitution of 1997 established a presidency constitutionally designed for arbitration yet institutionally incapable of compelling it, so that the realisation of the arbiter role depends entirely on the individual political will of the officeholder.

Introduction

The question of who arbitrates among the competing forces of a constitutional democracy lies at the heart of modern political theory. In systems where legislative and executive authority is distributed across multiple institutions, the stabilising function of a politically neutral adjudicator has long been regarded as a structural necessity rather than a mere decorative element of constitutional design. The intellectual lineage of this idea extends to Benjamin Constant, whose concept of the pouvoir neutre — a neutral power standing apart from and above the partisan fray — offered a theoretical resolution to the perennial problem of institutional deadlock ^[1]. Contemporary constitutional architects have translated this normative ideal into the formal architecture of republican presidencies, endowing heads of state with a range of competences intended to enable them to moderate conflicts, safeguard constitutional continuity, and act as guardians of the fundamental law. The Constitution of the Republic of Poland of 2 April 1997 represents one such translation, explicitly designating the President of the Republic as the guardian of the constitution and the arbiter of state authority in Article 126. The extent to which this normative designation corresponds to the actual conduct of the presidency in the Third Republic constitutes the central object of the present inquiry.

The significance of this research question extends well beyond the boundaries of academic constitutional doctrine. Poland's post-1989 democratic transition produced a system of government that has been characterised by scholars as a rationalised parliamentary republic with residual semi-presidential features, a characterisation that places the presidency in a structurally ambiguous position ^[2]. The President of the Republic is neither a purely ceremonial figurehead, as in classical parliamentary models, nor a dominant executive, as in presidential systems. This intermediate positioning creates a permanent interpretive tension: the constitutional text assigns the president a function of arbitration and neutrality, yet the political reality of partisan recruitment, electoral mandates, and cohabitation repeatedly invites and sometimes compels the exercise of prerogative powers in a decidedly non-neutral manner. When the presidency is occupied by a politician whose party simultaneously controls the Council of Ministers, the structural conditions for genuine arbitration are undermined from the outset. When the president and the prime minister emerge from opposing political camps, the relationship between the institutions tends to become a site of conflict rather than coordination. The scholarly and civic importance of examining how these structural pressures have shaped presidential conduct across five successive incumbencies cannot be overstated, particularly at a moment when the legitimacy of constitutional institutions in Poland is itself the subject of intense public and parliamentary contestation.

The present dissertation addresses three interconnected research questions. The first concerns the doctrinal content of the arbiter function: how is presidential arbitration defined within the framework of Polish constitutional doctrine, and what conceptual tools does legal scholarship offer for its analysis? The second question is normative and structural: which constitutional competences constitute the legal foundation of the presidential arbiter role, and how do they interact with the broader architecture of separation of powers under the 1997 Constitution? The third question is empirical: to what extent has the arbiter function been realised in the actual conduct of successive presidents of the Third Republic between 1990 and 2025, and what variables account for the observable variation in presidential behaviour across different political contexts? These questions are related but analytically distinct. The first operates at the level of constitutional theory, the second at the level of constitutional law, and the third at the level of political science and comparative institutional analysis. A rigorous engagement with all three levels is necessary if the conclusions of this dissertation are to possess both normative precision and empirical validity.

The justification for undertaking this research is both academic and practical. From the perspective of constitutional scholarship, the relationship between the normative design of executive institutions and their political practice represents one of the most productive areas of inquiry in contemporary public law. The presidential arbiter function has been discussed extensively in Polish constitutional doctrine, but systematic empirical analysis of its realisation across the full arc of the Third Republic remains comparatively sparse, particularly in comparative perspective ^[3]. Most existing studies either focus on the textual interpretation of Article 126 and its relationship to the broader constitutional framework, or address individual presidencies without placing them within a consistent analytical framework derived from constitutional theory. The present dissertation attempts to bridge this gap by applying a coherent set of criteria — derived from the theoretical concept of political arbitration — to the empirical record of five presidencies. From a practical standpoint, the Polish experience offers a case study of broader significance for the study of constitutional democracy in Central and Eastern Europe. The manner in which the presidential institution has been used, or refused, as a constitutional corrective in moments of political crisis illuminates the conditions under which formal constitutional design can and cannot constrain the behaviour of political actors holding prerogative powers.

The methodology employed in this dissertation combines constitutional dogmatic analysis with a comparative case-study approach. Constitutional dogmatic analysis provides the necessary tools for the interpretation of relevant constitutional provisions, in particular Article 126, Article 144(3), Article 122, Articles 133 and 134, and the emergency powers provisions of Chapter XI . This analysis draws upon the established doctrines of Polish constitutional law as well as the jurisprudence of the Constitutional Tribunal. The case-study approach is employed in Chapter Three, where the conduct of five successive presidents is assessed against a set of criteria derived from the theoretical framework elaborated in Chapter One. The selection of criteria — pertaining to the formal invocation of prerogative powers, the partisan alignment or neutrality of presidential conduct, and the relationship between presidential action and constitutional norm — is designed to permit a degree of structured comparison across cases that differ substantially in their political context. The primary sources consulted include the text of the 1997 Constitution and its preparatory materials, the case law of the Constitutional Tribunal, presidential statements and formal communications with parliament, and the secondary literature of Polish constitutional and political science scholarship ^[5]. The temporal scope of the empirical analysis extends from the establishment of the office of the President of the Republic of Poland in 1990 to the year 2025, encompassing the presidencies of Lech Wałęsa, Aleksander Kwaśniewski, Lech Kaczyński, Bronisław Komorowski, and Andrzej Duda.

The structure of the dissertation reflects the methodological logic described above and moves from the theoretical and doctrinal to the empirical and evaluative. The first chapter establishes the theoretical framework of the study. It traces the concept of political arbitration from its origins in Constant's pouvoir neutre through its reception in contemporary constitutional doctrine, surveys the principal models of executive government — presidential, semi-presidential, and parliamentary — and locates the Polish system within this typology ^[6]. The chapter then derives a working definition of presidential arbitration and identifies the analytical tension between constitutional design and political practice that organises the subsequent inquiry. The second chapter analyses the constitutional architecture of presidential competences as the normative foundation of the arbiter function. Particular attention is devoted to the so-called presidential prerogatives enumerated in Article 144(3), which the president exercises without the requirement of a countersignature by the Prime Minister, as these prerogatives constitute the structural infrastructure of presidential neutrality . The chapter also examines the suspensive legislative veto, the foreign and security policy competences, the appointment powers, and the emergency provisions, with particular attention to the zones of overlapping authority between the presidency and the Council of Ministers that have historically generated institutional conflict. The third chapter presents the empirical analysis of the five presidencies, assessing each against the criteria established in the first chapter and accounting for the structural and political variables that shaped presidential conduct in each case ^[8]. The chapter proceeds chronologically and culminates in a synthetic assessment of the overall trajectory of the presidential arbiter function across the period under examination. The conclusion draws together the theoretical, doctrinal, and empirical strands of the analysis and offers an evaluation of the principal findings in light of broader debates concerning the relationship between constitutional design and political behaviour.

The central thesis of this dissertation, which the foregoing analysis is intended to establish, may be stated in the following terms: the Constitution of the Republic of Poland of 1997 created a presidency that is constitutionally designed for political arbitration, but institutionally incapable of compelling it. The formal architecture of the presidential institution — the prerogatives, the veto, the guardianship clause of Article 126(2), the appointment powers — provides a sufficient normative foundation for the fulfilment of the arbiter function. What it cannot provide, and what no constitutional text can provide, is the political will to exercise that function in a manner consistent with its constitutional purpose. The empirical record of the Third Republic demonstrates that the realisation of the arbiter role has been contingent, above all, upon the individual orientation of successive presidents and upon the political context in which they have operated ^[9]. Periods of cohabitation have sometimes produced conduct approximating the arbiter ideal, as in the case of Aleksander Kwaśniewski, but have also generated acute institutional conflict, as in the case of Lech Kaczyński's relationship with the Tusk government. The most sustained departure from the arbiter model is observable in the conduct of Andrzej Duda, whose presidency combined near-unconditional support for the governing coalition of the Law and Justice party with aggressive use of the veto against the subsequent coalition government, a pattern that is difficult to reconcile with any plausible reading of the constitutional concept of presidential neutrality. These findings suggest that the effective realisation of the presidential arbiter function requires not only an appropriate constitutional framework — which Poland possesses — but also a political culture of institutional restraint and a conception of presidential office that prioritises constitutional fidelity over partisan advantage. The cultivation of such a culture cannot be legislated into existence; it must be achieved through the accumulation of precedents, the development of constitutional conventions, and, ultimately, the political choices of the individuals who occupy the highest office of the state.

Chapter 1. The Concept of Political Arbitration and Presidential Systems in Democratic Theory

1.1. The Notion of the Political Arbiter in Constitutional and Political Science Literature

The concept of the political arbiter, as applied to the head of state within a constitutional order, represents one of the more theoretically complex and practically contested ideas in the scholarship of constitutional law and comparative politics. Its intellectual genealogy may be traced to the early nineteenth century, when thinkers engaged with the problem of how a post-revolutionary constitutional state might prevent both executive usurpation and legislative tyranny without imposing an external authority above all branches of government. The challenge was to identify a power capable of moderating conflicts between constitutionally established institutions without itself becoming a fourth centre of political will or degenerating into an instrument of partisan interest. This theoretical preoccupation gave rise to what Benjamin Constant, in his Principes de Politique, designated the pouvoir neutre — a neutral, moderating power vested in the constitutional monarch, standing above the three classical powers and empowered to restore equilibrium whenever the constitutional order threatened to be disrupted. Though formulated in the monarchical context of the Restoration, Constant's concept provided the philosophical antecedent for modern theories of presidential arbitration within republics.

The transition of this concept into the republican constitutional tradition required substantial adaptation. In monarchies, the neutrality of the sovereign was both a constitutional convention and a social expectation reinforced by dynastic legitimacy. In republics, particularly those with popularly elected presidents, the theoretical neutrality of the head of state coexists in structural tension with the political circumstances of their election. The president who receives a democratic mandate in a competitive election is, by the very nature of that process, a political actor connected to a party, platform, and electoral coalition. To exercise genuinely arbitral functions — to stand above partisan competition, protect constitutional norms from infringement by whichever political faction commands the executive — requires a disposition of institutional self-restraint that the constitutional text may encourage but cannot guarantee. The structural tension between formal constitutional neutrality and the inherently political character of executive decision-making lies at the heart of the present inquiry.

The contribution of Maurice Duverger to the understanding of semi-presidential systems proved foundational for later theorisations of conditional arbitral functions. Duverger's recognition that in systems combining a popularly elected president with a prime minister and cabinet responsible to the legislature, the actual distribution of executive authority shifts in accordance with the composition of the parliamentary majority, illuminated the contingent character of presidential power. When the president's political alignment coincides with the parliamentary majority, the system tends toward the presidential pole; when a parliamentary majority of a different political orientation exists, a regime of cohabitation emerges in which the prime minister exercises dominant executive authority and the president retreats to a position structurally closer to the arbiter ideal. Cohabitation thus constitutes a paradigmatic illustration — involuntary and structurally induced — of arbitral presidential conduct under conditions of divided partisan control. The broader comparative study of divided government arrangements has confirmed that the formal institutional separation between a chief executive and a legislative majority creates distinctive governance dynamics that shape the exercise of constitutional authority across multiple levels of the state apparatus, as has been observed in studies of executive-legislative relations at the municipal level in Poland. ^[2]

Within Polish constitutional doctrine, the notion of the arbiter has been elaborated by scholars including Piotr Winczorek, Leszek Garlicki, and Marek Zubik, who have engaged with the question of how to characterise presidential competences under the Constitution of 2 April 1997. The consistent thread of this scholarship is that the constitutional provisions establishing the president as the supreme representative of the Polish state and the guarantor of the continuity of state authority do not vest the presidency with general executive power but rather with a distinctive set of competences oriented toward the preservation of constitutional order and systemic equilibrium. The president, on this interpretation, is neither a governing actor in the sense familiar from presidential republics nor a merely ceremonial figurehead comparable to constitutional monarchs in purely parliamentary systems; the presidential office occupies an intermediate position characterised by its arbitral orientation. In the broader context of democratic governance theory, the stability of the state and the integrity of its constitutional arrangements have been identified as foundational prerequisites for the welfare of the polity and the maintenance of the social fabric — a proposition consistent with the understanding that constitutional organs performing moderating functions contribute to what, in the study of governance structures, has been described as the optimisation of systemic stability and sovereignty. ^{[4, s. 6]}

For the purposes of this dissertation, a working definition of political arbitration is proposed as follows: the exercise of constitutionally vested powers by the head of state with the purpose of preserving systemic equilibrium, protecting constitutional norms from infringement by other state organs or political actors, and mediating conflicts among constitutional institutions, without subordinating those powers to a partisan programme or making them instrumentally dependent on the electoral or political interests of the president's own political formation. This definition distinguishes the arbiter from the constitutional guardian in the strict sense — the role of defending the formal text of the constitution through referrals to the constitutional court — and from the symbolic figurehead, whose functions are exhausted in the representation of state unity. The arbiter, properly understood, exercises substantive powers in a manner oriented toward constitutional equilibrium rather than political advantage; the normative standard implied by this definition provides the criterion against which the empirical record of presidential practice, examined in Chapter 3, will be assessed.

1.2. Models of Executive Power: Presidential, Semi-Presidential, and Parliamentary Systems

Comparative constitutional scholarship has long distinguished three principal models of democratic government according to the institutional relationship between the executive and the legislature: the presidential, the semi-presidential, and the parliamentary system. This typology, elaborated in the foundational works of scholars including Arend Lijphart, Juan Linz, and Giovanni Sartori, provides the indispensable structural framework within which the specific characteristics of the Polish constitutional arrangement and the particular expression of the presidential arbiter function must be situated. While each model exhibits considerable internal variation, the classification retains analytical utility insofar as it captures the fundamental constitutional logic governing the accountability, appointment, and removal of the executive branch.^{[11, s. 154]}

The presidential model, exemplified in its most developed form by the constitutional order of the United States, is defined by a strict separation of powers between the executive and legislative branches. The president receives an independent democratic mandate through direct popular election, serves a fixed term insulated from parliamentary confidence, and combines within a single office both the ceremonial representation of state unity and the direction of governmental policy. Cabinet members serve at the pleasure of the president and bear no collective responsibility to the legislature. The structural consequence of this arrangement is a profound constitutional fusion of the governing executive function with the symbolic function of representing the state, leaving no institutional space for a genuinely neutral arbiter standing above partisan politics. The head of state in a presidential system is both the chief executive and the symbolic representative of national unity; the two roles reinforce rather than moderate each other's political character.

The parliamentary model, by contrast, concentrates executive authority in a council of ministers or cabinet that depends upon the confidence of the legislature for its tenure. The head of state — whether a hereditary monarch or a president elected by the legislature or an electoral college — exercises functions primarily of a formal or representational character, with governmental policy direction vested in the prime minister and cabinet. The countersignature mechanism, whereby acts of the head of state must be endorsed by a minister who thereby assumes constitutional responsibility, operationalises the reduction of presidential authority to its symbolic dimension. Within this broad model, the Westminster variant features a more concentrated executive authority in the cabinet, while continental European adaptations have produced what constitutional scholars designate rationalised parliamentary systems — arrangements incorporating constitutional devices intended to stabilise the relationship between the cabinet and the legislature. The German konstruktives Misstrauensvotum (constructive vote of no confidence) and the Spanish mechanisms of government formation exemplify this rationalising tendency in the post-war European constitutional tradition.

The semi-presidential model occupies an intermediate position. In its minimalist definition, it combines a popularly elected president serving a fixed term with a prime minister and cabinet formally responsible to the parliament. The distribution of actual executive authority between the president and the prime minister within this structural framework is variable — dependent upon constitutional provisions, political conventions, and the party-political configuration of the parliament. Robert Elgie's influential reformulation of the typology distinguishes between president-parliamentary subtypes, in which the prime minister is responsible both to the president and to the parliament, and premier-presidential subtypes, in which the prime minister is responsible exclusively to the parliament. The latter arrangement creates the structural conditions under which cohabitation becomes possible: the president cannot dismiss a prime minister who commands a parliamentary majority, and is therefore constrained to accept governmental authority exercised by a prime minister of a different political orientation. The experience of French cohabitation in 1986–1988, 1993–1995, and 1997–2002 constitutes the most studied illustration of this dynamic in the European context.

Table 1.1. Comparative Characteristics of Major Models of Democratic Executive Power
Criterion	Presidential System	Semi-Presidential System	Parliamentary System
Election of Head of State	Direct popular election	Direct popular election	Indirect election or hereditary
Term of Head of State	Fixed term	Fixed term	Variable (often fixed)
Cabinet Responsibility	To president only	To parliament (premier-presidential) or to both (president-parliamentary)	To parliament only
Direction of Executive Policy	President	Shared and variable	Prime minister and cabinet
Possibility of Cohabitation	None	Structurally possible	Not applicable
Role of Head of State	Chief executive	Arbiter or limited executive	Ceremonial and representational

The Polish constitutional arrangement defies simple classification within the tripartite typology, though it is most accurately characterised as a rationalised parliamentary system retaining residual semi-presidential features. The formal constitutional structure places the Council of Ministers at the centre of executive authority, making the cabinet responsible to the Sejm (lower house of parliament) and subjecting the government's tenure to parliamentary confidence. The president, however, is elected by direct popular vote for a five-year fixed term — a feature characteristic of semi-presidential systems — and is vested with defined constitutional competences in national security, foreign policy, and constitutional guardianship that exceed the purely ceremonial functions of parliamentary heads of state. As has been observed in comparative scholarship on post-communist institutional development, the adoption of an unambiguous institutional framework tends to reinforce political stability, while multi-vector arrangements create ambiguity susceptible to exploitation in ways that undermine constitutional equilibrium. ^{[1, s. 225]} In the broader context of democratic governance theory, the principle has been articulated that governance structures ought to reinforce the values of the political system of which they form a part, thereby optimising systemic stability and safeguarding sovereignty — a principle that informed the constitutional designers of 1997. ^{[4, s. 66]}

The presidential model concentrates both governing and symbolic functions in the office of the president, leaving no institutional space for neutral constitutional arbitration between branches.^{[12, s. 103]}
The rationalised parliamentary model vests executive authority in the cabinet while assigning the head of state a discrete set of competences oriented toward constitutional equilibrium rather than governmental direction.
The semi-presidential model creates conditions in which genuine arbitral conduct may be structurally induced by cohabitation, though the extent of arbitral function depends substantially upon constitutional design and political convention.^{[13, s. 94]}
Poland's constitutional arrangement combines direct presidential election with a parliamentary cabinet system, producing an office whose formal institutional logic is parliamentary but whose electoral legitimacy is rooted in a direct popular mandate that complicates the performance of strictly neutral arbitration.

1.3. The Polish Constitutional Tradition and the Presidential Office

The constitutional history of Poland offers an exceptionally instructive laboratory for the study of executive design, presenting within the space of the twentieth century a series of constitutional experiments spanning the full range of possibilities from extreme parliamentary weakness of the executive to unchecked presidentialism. The characteristic oscillation between these poles — each associated in Polish political memory with specific and severe political pathologies — provided the experiential foundation upon which the drafters of the 1997 Constitution drew when constructing the institutional architecture of the Third Republic. An understanding of this historical trajectory is therefore indispensable for a proper interpretation of the constitutional provisions governing the presidency and, in particular, for an appreciation of the deliberate choices made to situate the president in the role of a constitutional arbiter rather than a governing executive.

The March Constitution of 1921, adopted in the immediate aftermath of the restoration of Polish statehood, embodied a parliamentary model of government that was in significant respects a reaction against the executive power of the partitioning empires and a reflection of the political anxieties of a National Assembly dominated by parties suspicious of concentrated executive authority.^{[14, s. 188]} The president of the republic was to be elected by the National Assembly rather than by direct popular suffrage, thereby lacking an independent democratic mandate; executive acts required ministerial countersignature; and the range of personal prerogatives was deliberately limited. The Council of Ministers bore collective responsibility to the Sejm, which possessed wide powers to bring governments to a fall. The institutional consequences were severe: the period from 1921 to 1926 witnessed a rapid succession of governments unable to maintain stable parliamentary coalitions, a chronic incapacity to address mounting economic and political challenges, and an executive too constitutionally weak to provide effective governance even under conditions of acute national emergency.

The May Coup of 1926, led by Józef Piłsudski, constituted the moment at which the failure of extreme parliamentarism became the legitimating premise for a wholly different constitutional philosophy. The April Constitution of 1935, adopted under the Sanacja regime, represented the antithesis of the 1921 arrangement: it vested in the president almost unchecked authority, making the president responsible only before God and history, subordinating all state institutions to presidential supremacy, and concentrating in the presidential office an aggregation of powers that effectively negated the separation of powers as a constitutional principle. This arrangement, however, was inseparable from authoritarian governance; the presidency under the 1935 constitution was not a neutral arbiter standing above constitutional institutions but an apex of power that subordinated those institutions to the will of the ruling formation. The constitutional binary thus inscribed in Polish political memory — parliamentarism associated with governmental instability, presidentialism associated with authoritarianism — created a profound institutional dilemma for the designers of the post-communist constitutional order.

The transformations initiated in 1989, while embedding Poland firmly in a process of democratic consolidation, temporarily reproduced rather than resolved this dilemma. The Amendment to the Constitution of 7 April 1989 and the Little Constitution of 1992 created a hybrid executive arrangement in which a directly elected president possessed substantial but incompletely defined powers overlapping with those of the prime minister and Council of Ministers. As has been documented in comparative scholarship on post-communist institutional transitions, the multi-vector character of political arrangements tends to produce ambiguity susceptible to political exploitation, in contrast to systems in which the institutional choices are clear and the lines of accountability are unambiguous. ^{[1, s. 225]} The conflicts between President Lech Wałęsa and successive governments during the period 1989 to 1995 — characterised by observers as a 'war at the top' — provided graphic empirical evidence of the dysfunctional consequences of constitutional ambiguity in the domain of executive authority. These conflicts were not merely a product of personality or political circumstance; they were structurally enabled by a constitutional framework that left fundamental questions of executive authority unresolved.

The March Constitution of 1921 embodied a parliamentary model that deliberately weakened the executive, resulting in governmental instability and the constitutional crisis of 1926.
The April Constitution of 1935 represented the opposite extreme, concentrating unchecked authority in a presidency that operated without effective constitutional constraint and in conditions incompatible with democratic governance.
The hybrid transitional arrangements of 1989 to 1997 reproduced institutional ambiguity, generating chronic conflicts between presidential and governmental institutions that provided the empirical backdrop for the constitutional drafting of 1997.
The accumulated experience of these constitutional phases provided the normative and historical foundation from which the drafters of the 1997 Constitution drew their central institutional choices regarding the presidential office.

It is worth noting, in the broader context of comparative constitutional experience, that the relationship between the institutional design of the executive and the character of political and economic relations has been observed to carry significant systemic consequences. A parliamentary-cabinet system of the kind that was taking shape in Poland from the outset of its democratic transformation proved less susceptible to the consolidation of informal political-economic relationships than more presidentially oriented systems, in which the concentration of executive power has been associated with the emergence of oligarchic structures and elevated levels of systemic corruption. ^{[1, s. 239]} The Polish constitutional choice of rationalised parliamentarism thus carried implications extending well beyond the formal distribution of competences between constitutional organs; it shaped the broader political and economic character of the emerging democratic order.

1.4. The Constitution of 1997 and the Rationalised Parliamentary System

The Constitution of 2 April 1997 constitutes the normative foundation of the entire analytical enterprise undertaken in this dissertation. Its adoption marked the definitive conclusion of the post-communist constitutional transition and the establishment of a stable institutional framework within which the relationship between the president, the government, and the parliament has been subsequently ordered. The constitutional drafting process, conducted by the Commission for Constitutional Matters of the National Assembly from 1993 to 1997, proceeded against the background of the institutional conflicts of the Wałęsa years and was animated by the determination to resolve, once and for all, the ambiguities that had made those conflicts structurally possible. The result is a constitutional settlement best characterised as a rationalised parliamentary system — one in which parliamentary logic is paramount, reinforced by formal mechanisms designed to prevent governmental instability, and within which the president is assigned the constitutionally specific role of arbiter.

The core structural choice of the 1997 Constitution is the placement of executive authority in the Council of Ministers, which, under Article 146, carries out internal and foreign affairs of the state not reserved for other constitutional organs. The prime minister, as the head of the Council of Ministers, directs its work, coordinates cabinet activities, and is the primary political interlocutor of the parliamentary majority. Cabinet ministers bear individual and collective responsibility to the Sejm, and the government's tenure depends upon the confidence of the lower chamber. The constructive vote of no confidence — requiring the simultaneous election of a successor prime minister before the incumbent may be removed — prevents the parliament from merely destroying governments without constructing alternatives, thereby addressing the pathology that had undermined Polish parliamentarism in the interwar period. Within this framework, the Council of Ministers is unambiguously the principal locus of executive authority, and the president is definitionally excluded from the direction of day-to-day governmental policy.

The president of the republic is assigned a distinct constitutional role through Article 126, which designates the president as the supreme representative of the Republic of Poland and the guarantor of the continuity of state authority. This provision has been identified by Polish constitutional doctrine as the textual foundation of the arbiter concept: the president's representational function encompasses not merely the external representation of the state but also the internal function of standing as a symbol of state unity and constitutional continuity above the partisan competition that governs the relationship between the government and the opposition. The guarantee of continuity of state authority implies, moreover, that the president possesses a constitutional responsibility to intervene when the functioning of other constitutional organs threatens the integrity of the constitutional order, though the forms of such intervention are strictly defined by the constitution and may not be improvised beyond the competences expressly conferred. In the context of democratic governance theory more broadly, representative democratic institutions are understood as practical arrangements chosen for their capacity to maintain the stability of the social fabric and to safeguard the sovereignty of the self-governing polity — functions that the 1997 constitutional architecture assigns, in their specifically presidential dimension, to the arbiter office. ^{[4, s. 17]}

The countersignature mechanism, codified in Article 144, operationalises the constitutional delineation between the president's arbitral and governing functions. The general rule is that acts of the president require the countersignature of the prime minister, who thereby assumes political responsibility before the Sejm. The constitutional enumeration of personal prerogatives — acts that the president may perform without countersignature — defines the sphere of genuine presidential autonomy. These prerogatives include the referral of legislation to the Constitutional Tribunal (Trybunał Konstytucyjny, TK), the exercise of the legislative veto, the submission of bills to the Sejm on matters within presidential constitutional competence, the designation of candidates for certain high state offices, and various acts in the domain of national security and appointments. The structure of this enumeration is significant: the prerogatives constitute a defined and limited set of instruments adequate to the performance of arbitral functions without constituting a parallel government. In the context of comparative scholarship on constitutional institutions, it has been noted that Polish constitutional arrangements accommodate organs whose position does not map directly onto the classical tripartite division of powers — a recognition that the constitutional order of 1997 is sufficiently complex to establish institutions fulfilling specialised constitutional functions that cut across classical branch boundaries. ^{[3, s. 9]}

Table 1.2. Key Constitutional Provisions Establishing the Presidential Arbiter Role under the Constitution of 1997
Provision	Content	Arbitral Function Served
Article 126 §1	President as supreme representative of the Republic of Poland	Representational unity and symbolic continuity
Article 126 §2	President as guarantor of continuity of state authority and constitutionality	Constitutional guardianship and systemic equilibrium
Article 122 §5	Presidential legislative veto (suspensive)	Checking legislative excess and unconstitutional enactment
Article 122 §3	Referral of legislation to the Constitutional Tribunal	Norm protection and constitutionality review
Article 144 §3	Personal prerogatives exercised without countersignature	Autonomous competences for arbitral intervention
Article 98 §4–5	Limited power to shorten the Sejm's term of office	Ultimate sanction preserving constitutional function of parliament

The relationship between the formal constitutional design and the actual exercise of presidential functions constitutes the central analytical tension of this dissertation. The constitutional text of 1997 establishes, with considerable precision, the institutional architecture within which the arbiter function is to be performed. It assigns the president defined competences, constrains the remainder of presidential activity within the countersignature regime, and through Article 126 provides the normative orientation that should govern the exercise of those competences. What the constitutional text cannot accomplish — as the empirical analysis in Chapter 3 will demonstrate — is to compel the individual holder of the presidential office to exercise these competences in a manner consistent with the arbitral orientation that the constitutional architecture implies. The responsible exercise of authorised constitutional discretion requires reasoning in accordance with the values of the system one serves, and the choice of a particular system of government implies the adoption of a corresponding set of political values; ^{[4, s. 28]} yet the internalisation of those values and their consistent expression in presidential conduct remains dependent upon the political disposition of the individual incumbent.

The design principle articulated in comparative democratic governance scholarship — that governance structures optimise systemic stability and safeguard sovereignty when they reinforce the values of the political systems of which they are part ^{[4, s. 66]} — describes the aspiration of the 1997 constitutional arrangement. The presidential office as designed embodies this principle: its competences are calibrated to the value of systemic equilibrium within a parliamentary constitutional order, neither so extensive as to constitute a competing executive authority nor so narrow as to render the office unable to fulfil its constitutional mission. The subsequent chapters of this dissertation examine the extent to which the successive presidents of the Third Republic exercised their constitutional competences in fidelity to this design, and assess the implications of the resulting patterns of presidential conduct for the understanding of political arbitration as a constitutional phenomenon in the Polish context.

Article 126 of the 1997 Constitution provides the normative foundation for the arbiter concept, designating the president as the guarantor of constitutional continuity above the partisan competition of ordinary governmental politics.
Article 144 and its enumeration of personal prerogatives delineates the sphere of autonomous presidential action adequate to the performance of arbitral functions without constituting a parallel governing authority in competition with the Council of Ministers.
The constructive vote of no confidence and other mechanisms of rationalised parliamentarism establish the institutional environment within which presidential arbitration operates, characterised by parliamentary primacy and cabinet stability rather than executive concentration.
The central analytical tension of this dissertation resides in the gap between the constitutional design of the arbiter role and its actual realisation in presidential practice — a gap that reflects the impossibility of guaranteeing by constitutional text alone the dispositional orientation required for genuine constitutional arbitration.

Chapter 2. Constitutional Competences of the President of the Republic of Poland

2.1. The Prerogatives of the President: Competences Exercised Without Countersignature

The constitutional position of the President of the Republic of Poland is defined, in the first instance, by the distinction between ordinary presidential acts and those exercised as prerogatives — a distinction that carries fundamental implications for the architecture of executive authority within the parliamentary order established by the Constitution of 1997. Article 144(2) of the Constitution establishes the general rule: the validity of presidential acts is conditional upon the countersignature of the President of the Council of Ministers, who thereby assumes political responsibility before the Sejm. This institution, inherited from the traditions of parliamentary constitutional government, ensures that the minister who countersigns a presidential act bears democratic accountability for its political consequences, maintaining the parliamentary logic of ministerial responsibility. Article 144(3) introduces the exception: it enumerates thirty specific competences — the presidential prerogatives — that the President exercises independently, without countersignature, bearing personal political responsibility for their exercise in the constitutional order.

The prerogative list is exhaustive and closed in character, constituting a numerus clausus of autonomous presidential powers. This closed structure is constitutionally significant: it is intended to confine autonomous presidential action to the categories the constitutional legislator has deliberately identified as appropriate for independence from governmental co-decision, thereby preventing the President from claiming prerogative authority in contexts not expressly enumerated. Doctrinal analysis has, however, noted that the demarcation between prerogatives and countersigned acts is not always self-evident, and interpretive disputes have arisen in constitutional practice concerning the precise boundary between the two categories — a phenomenon that reflects the inherent tension between formal enumeration and the open-textured character of constitutional language, which cannot anticipate every institutional configuration.

The thirty prerogatives may be systematised into five thematic groupings, reflecting the constitutional purpose served by autonomous presidential action in each domain. The first group concerns relations with the legislature: the President may convene the inaugural sessions of newly elected chambers, order a national referendum with Senate consent, exercise the right of legislative initiative, refer legislation to the Constitutional Tribunal (Trybunał Konstytucyjny, hereinafter TK), and dissolve the Sejm in constitutionally prescribed circumstances. The second group relates to governmental formation: the designation and acceptance of the resignation of the Prime Minister, and the acceptance of the resignation of the Council of Ministers in crises of parliamentary confidence. The third group encompasses matters of state honour and personal status: conferring citizenship, granting pardons, and conferring orders and decorations. The fourth group covers appointments to judicial, financial, supervisory, and regulatory institutions. The fifth group pertains to national security and the armed forces, including the Supreme Command and the appointment of senior military officers.

Table 2.1. Presidential Prerogatives under Article 144(3): Thematic Classification
Category	Key Prerogatives	Constitutional Function
Legislative Relations	Convening sessions; ordering referenda; legislative initiative; TK referral; Sejm dissolution	Constitutional supervision; democratic correction
Executive Formation	Designation and dismissal of Prime Minister; acceptance of governmental resignation	Governmental stability; arbitral role in executive crises
Judicial and Institutional Appointments	TK justices; First President of the Supreme Court; judges; NBP President	Independence of constitutional and judicial institutions
National Security and Armed Forces	Supreme Command; appointment of Chief of the General Staff; wartime Commander-in-Chief	State security; civilian control of the military
Personal Prerogatives	Granting pardon; conferring citizenship; orders and decorations	Sovereign mercy; state honour

The constitutional significance of the prerogative list resides in its relationship to the arbiter thesis: autonomous competences constitute the constitutional infrastructure of presidential neutrality, enabling the head of state to act as a corrective force — whether by initiating constitutional review, declining to accept a governmental resignation, or exercising the power of pardon — without requiring governmental consent for the very acts that constitute this correction. Without the autonomous sphere carved out by Article 144(3), the President would, as a practical matter, be unable to function as a constitutional counterweight to the government and the parliamentary majority, since every act of correction would require the prior agreement of the actors being corrected. An important qualification must, however, be registered: formal independence from countersignature does not invariably translate into substantive independence from political influence. Presidential discretion in the exercise of prerogatives is conditioned, in practice, by the political dynamics of institutional relationships, parliamentary reactions, and the reactions of public opinion — a gap between formal autonomy and effective independence that will be examined in the empirical analysis of Chapter 3.

2.2. The Presidential Veto and the Role of the President in the Legislative Process

The President's participation in the legislative process constitutes one of the most visible dimensions of the constitutional arbiter function, and the suspensive veto stands at its centre as the primary instrument of presidential correction of legislative decisions. Article 122 of the Constitution of 1997 establishes the framework within which the President operates upon receipt of a bill passed by both chambers of the National Assembly: the President must, within twenty-one days, either sign the act into law, refer it to the TK for prior constitutionality review, or return it to the Sejm with reservations — the act commonly designated the presidential veto. These three options are not simultaneously available in relation to the same bill: the constitutional logic of Article 122 forecloses the sequential deployment of TK referral followed by a veto on identical grounds, preventing the accumulation of corrective instruments against a single piece of legislation.

The procedural mechanics of the veto reflect a deliberate constitutional calibration between the corrective authority of the President and the primacy of the elected parliamentary majority. A bill returned to the Sejm with presidential reservations may be re-adopted by a three-fifths majority of votes cast in the presence of at least half of the statutory number of deputies — a qualified majority substantially higher than the simple majority by which legislation is ordinarily adopted, yet not so elevated as to render override practically impossible under stable coalition government. This configuration places the veto in an intermediate constitutional zone: it is sufficiently meaningful to create a genuine deliberative pause and to force parliamentary reconsideration, yet sufficiently surmountable to preserve the ultimate primacy of the legislature. Upon a successful override, the President is constitutionally obliged to sign the legislation; no further presidential resistance is constitutionally permissible, and the enactment proceeds to promulgation.

The alternative path of TK referral carries distinct constitutional implications. Submission of a bill to the TK under Article 122(3) engages the President not as a political veto-player but as a constitutional guardian: the referral presents presidential objection in the register of constitutional principle rather than political interest, and it invites a binding determination by the organ constitutionally designated for the resolution of constitutional doubt. Should the TK uphold the bill's constitutionality, the President is bound to sign without the option of subsequently invoking the veto on the same grounds; should the TK find unconstitutionality, the President refuses signature in accordance with the binding adjudication. The normative integrity of this mechanism as an arbiter instrument depends upon the good faith deployment of the referral — its use to raise genuine constitutional doubts, rather than to obstruct legislation on political grounds under a constitutional guise.

The principal features of the President's legislative role may be summarised as follows:

The presidential right of legislative initiative under Article 118 enables the direct submission of bills to the Sejm without governmental intermediation, conferring a constitutionally significant capacity to shape legislative agendas.
The twenty-one day review period creates a structured deliberative pause in the enactment process, during which constitutional objections may be articulated and institutional dialogue initiated.
The three-fifths override threshold is substantially higher than the ordinary legislative majority, providing genuine — though not insuperable — protection against precipitate legislative action.
The mutual exclusivity of TK referral and the veto in relation to the same bill forecloses the simultaneous deployment of both instruments as compounding obstructive mechanisms.
The budgetary bill is governed by a distinct shortened regime under Article 224, with a seven-day presidential review period, reflecting the constitutional priority of fiscal continuity.
Presidential signature constitutes the formal act of promulgation; no legislation acquires the force of law without it, giving even the act of signature a constitutionally non-trivial character.

The veto as an arbiter instrument operates most effectively when deployed in conditions of genuine constitutional concern or to protect constitutional values against majoritarian overreach — that is, when its use reflects a judgment that transcends the ordinary competition of political forces. Its normative integrity is compromised when it is employed as an instrument of partisan obstruction, transforming a constitutional check into a weapon of political warfare between the presidency and the governing coalition. The empirical distinction between these two modalities of use cannot be resolved from formal analysis of the prerogative alone; it requires attention to the substantive grounds cited, the pattern of deployment across legislative programmes, and the correlation between veto use and political alignments — matters that will be examined in the empirical analysis of the following chapter.

2.3. Competences in the Domain of Foreign Policy and National Security

Foreign and security policy represents, in comparative constitutional terms, one of the most structurally ambiguous domains of presidential competence, characterised by a deliberate constitutional design that does not resolve the distribution of authority between the President and the Council of Ministers with the precision found in purely domestic constitutional arrangements. Article 133 designates the President as the supreme representative of the state in international relations: the President ratifies and denounces international agreements, appoints and recalls diplomatic representatives, and accredits the representatives of foreign states and international organisations. These functions situate the head of state as the formal embodiment of Polish statehood in the international arena. Article 133(3), however, introduces a duty of cooperation — the President cooperates with the Prime Minister and the minister responsible for foreign affairs in the exercise of foreign policy — a provision that signals the absence of a presidential monopoly over external relations and the co-responsibility of the cabinet.

The structural complexity is sharpened by Article 146, which assigns to the Council of Ministers the general competence over internal and external policy, including the conduct of international relations. The President and the Council of Ministers thus operate within a zone of constitutionally overlapping jurisdictions in external affairs, the practical management of which depends significantly upon the political relationship between the head of state and the governing coalition. In conditions of institutional cohesion, this overlap produces cooperative foreign policy conduct; in conditions of cohabitation or sustained institutional conflict, it generates competition that may undermine the coherence of the state's external representation. The Constitution deliberately leaves this tension unresolved, entrusting its management to the constitutional actors themselves and to the political culture of democratic cooperation between institutions of differing political orientations.

Presidential competences in national security and the armed forces constitute a constitutionally grounded dimension of this domain. Article 134 designates the President as the Supreme Commander of the Armed Forces in peacetime, with supreme command exercised through the Chief of the General Staff. In the context of the Polish armed forces command and control system, direction of the armed forces in peacetime is in practice realised through the Minister of National Defence, who serves as the organ through which the President of the Republic exercises nominal peacetime supreme authority over the armed forces. ^{[6, s. 11]} As study of the Polish command structure illustrates, the armed forces play a distinctive role in the political system, and the shape of that system has been significantly determined by the preferences of political actors holding state power at any given moment — as evidenced by the successive reforms of 2014 and 2018, which reflected contrasting governmental conceptions of the optimal command architecture. ^{[6, s. 11]} The Chief of the General Staff occupies the strategic level of command and is appointed by the President of the Republic in accordance with the current constitutional order, ^[6] constituting a presidential prerogative that provides the head of state with a structurally significant point of influence over the military command hierarchy.

In wartime, the constitutional position of the President is substantially transformed. Article 134(4) empowers the President, upon a request from the Prime Minister, to appoint the Commander-in-Chief of the Armed Forces — a position carrying substantially greater operational authority than the mediated peacetime supreme command. The National Security Council (Rada Bezpieczeństwa Narodowego, hereinafter NSC), established under Article 135 and presided over by the President, serves as an advisory body in matters of internal and external security. Its consultative status means that it does not independently generate binding security policy; rather, it constitutes a framework for institutional coordination under presidential chairmanship. The arbiter potential of presidential security competences is thus real but structurally constrained: nominal peacetime supreme command, mediated through the Minister of National Defence and the Chief of the General Staff, affords the President institutional authority whose practical exercise depends significantly upon the degree of political cooperation between the presidency and the government.

2.4. Appointment Powers and Influence Over the State Apparatus

Presidential appointment competences represent a structural mechanism of durable institutional influence whose significance extends well beyond the immediate moment of appointment: by shaping the composition of key state organs over the multi-year terms of appointees, the power to appoint constitutes a form of lasting presidential presence within the constitutional architecture that persists long after any particular government has departed office. The appointment powers of the President encompass four principal domains: the judiciary and constitutional review; financial and monetary governance; supervisory and audit institutions; and media regulation.

In the domain of the judiciary, the President's appointment competences are constitutionally the most consequential. The President appoints justices of the TK following a Sejm resolution, appoints the First President of the Supreme Court from among candidates presented by the General Assembly of Supreme Court Justices, and formally appoints judges to all courts upon the recommendation of the National Council of the Judiciary (Krajowa Rada Sądownictwa, hereinafter KRS). These judicial appointment competences place the President in a structurally significant relationship with the organs of constitutional adjudication: by selecting those who interpret and apply the Constitution and the law, the President exercises, over time, an indirect but durable influence over the character of the legal order that transcends the temporal limits of any presidential term. In the domain of financial governance, the President appoints the President of the National Bank of Poland (Narodowy Bank Polski, hereinafter NBP) upon Sejm recommendation and appoints members of the Monetary Policy Council from among candidates nominated by the Sejm, Senate, and the President respectively — appointments whose consequences for monetary independence extend across multi-year institutional terms. Presidential appointments also extend to the National Broadcasting Council (Krajowa Rada Radiofonii i Telewizji, hereinafter KRRiT), an organ whose tripartite appointment structure — shared between the President, Sejm, and Senate — reflects the constitutional intent to insulate media regulation from any single political authority.

Table 2.2. Principal Presidential Appointment Competences by Institutional Domain
Institutional Domain	Organ / Position	Constitutional Basis	Constitutional Purpose
Constitutional Review	Constitutional Tribunal justices	Art. 194(1)	Integrity of constitutional adjudication
Supreme Judiciary	First President of the Supreme Court	Art. 183(3)	Independence of the supreme judicial institution
Judicial Administration	Judges across all court levels (upon KRS recommendation)	Art. 179	Independence and integrity of the judiciary
Central Banking	NBP President; Monetary Policy Council members	Art. 227	Monetary independence; macro-financial stability
State Audit	President of the Supreme Audit Office	Art. 205(1)	Governmental accountability and expenditure oversight
Rights Protection	Commissioner for Human Rights	Art. 209(1)	Defence of constitutional rights against governmental overreach
Media Regulation	Members of the National Broadcasting Council (KRRiT)	Art. 215	Media pluralism; freedom of expression

The appointment of the Commissioner for Human Rights (Rzecznik Praw Obywatelskich) and the President of the Supreme Audit Office deserves particular attention from the perspective of the arbiter function. Both institutions serve as constitutional oversight mechanisms: the Commissioner defends the rights and freedoms of citizens against overreach by governmental authorities, while the Audit Office reviews the legality, economy, and efficiency of state expenditure and public finances. Presidential appointments to these bodies carry implications not merely for institutional composition but for the orientation and vigour of oversight functions that are constitutionally designed to operate independently of political authority. An appointment process exercised in fidelity to the arbiter role would be expected to favour candidates of demonstrated professional independence; appointments motivated by partisan considerations undermine the very independence that gives these institutions their constitutional purpose and their capacity to function as effective checks within the constitutional order.

The Constitutional Tribunal appointment crisis that began in 2015 constitutes a paradigm case that crystallised the dual potential of appointment powers as instruments either of constitutional equilibrium or of constitutional destabilisation. The disputed appointments of TK justices in 2015 and the ensuing institutional confrontations illustrated that the formal presidential prerogative to appoint Tribunal justices is susceptible to deployment in ways that fundamentally alter the character of constitutional adjudication, with systemic consequences extending across the legal and political order. This episode demonstrates that appointment powers are not neutral instruments of institutional composition but among the most consequential exercises of presidential authority under the 1997 Constitution — their normative character defined not by their formal exercise alone but by the institutional logic and constitutional fidelity with which they are deployed, and by the extent to which they reinforce or erode the independence of the institutions they nominally serve.

2.5. Emergency Powers and the Constitutional Duty to Safeguard the Constitution

The constitutional position of the President encompasses, alongside the ordinary competences analysed in the preceding subsections, a distinct set of emergency powers engaged in conditions of extraordinary threat to the state and the constitutional order, and a broader constitutional mandate — articulated in the oath formula of Article 130 and the guardian clause of Article 126(2) — to serve as the protector of the Constitution itself. These two dimensions are analytically distinct but constitutionally interconnected: the emergency regime defines the outermost boundary of coercive executive authority under the constitutional order, while the guardian mandate establishes the normative framework within which all presidential competences are to be exercised in conditions both of normalcy and of institutional stress.

The Constitution establishes three categories of constitutional emergency. Martial law, governed by Article 229, may be introduced by the President upon the request of the Council of Ministers in the event of armed aggression against the territory of the Republic or where an international agreement imposes a corresponding obligation. The state of emergency under Article 230 may be introduced upon governmental request in the event of threats to the constitutional order, security of citizens, or public order of sufficient gravity to require extraordinary governmental measures. The state of natural disaster under Article 232 may be introduced by the Council of Ministers to prevent or remove the consequences of natural disasters or technological accidents. Each regime is subject to constitutional safeguards: time limits, parliamentary oversight, and the requirement of governmental initiative in the most coercive instances. The constitutional design of these provisions reflects a deliberate effort to confine executive emergency powers within legally defined parameters, reflecting awareness of the historical susceptibility of emergency regimes to authoritarian abuse.

A constitutionally significant feature of the presidential role in the emergency regime is the requirement of governmental initiative: both martial law and the state of emergency are introduced by the President upon a request from the Council of Ministers, not on unilateral presidential initiative. This structure prevents the President from unilaterally imposing emergency conditions, preserving the parliamentary principle that the most consequential exercises of public authority require the concurrence of the democratically accountable government. The Sejm retains the authority to lift emergency measures or to decline approval, maintaining parliamentary oversight over executive emergency action and ensuring that emergency powers remain subject to democratic control even in conditions of systemic stress. The constitutional order thus treats emergency powers not as a domain of unconstrained executive prerogative but as a constitutionally circumscribed regime activated by institutional consensus and subject to legislative correction.

The broader constitutional duty of guardianship is grounded in two textual provisions of the Constitution. Article 130, prescribing the presidential oath, requires the President to solemnly commit to faithfully serving the Polish Nation, observing the provisions of the Constitution, and guarding the sovereignty and security of the state, as well as the inviolability and integrity of its territory. Article 126(2), the guardian clause, declares that the President shall watch over the observance of the Constitution, guard the sovereignty and security of the state, and the inviolability and integrity of its territory. Read together, these provisions establish a constitutional mandate that exceeds the sum of the enumerated prerogatives and competences, charging the presidency with a meta-function of constitutional guardianship that encompasses but is not reducible to specific acts, and that provides the normative criterion against which all exercises of presidential authority are ultimately to be assessed.

The doctrinal debate over the normative content of Article 126(2) has generated two principal interpretive positions. The first holds that the guardian clause is exclusively programmatic in character: it establishes a constitutional objective and a criterion for the evaluation of presidential conduct, but does not itself confer autonomous juridical competences beyond those enumerated in the remaining constitutional provisions. On this view, the President may not invoke Article 126(2) as a freestanding legal basis for action not otherwise authorised by specific constitutional provisions, and any attempt to do so would transgress the formal logic of the closed prerogative system. A contrasting position treats the guardian clause as conferring a residual constitutional mandate that, in exceptional circumstances, may authorise presidential action beyond the enumerated list — a position constitutionally problematic because it introduces an open-ended basis for presidential intervention that resists legal confinement and risks transforming a normative aspiration into an instrument of institutional overreach. The first position is doctrinally more consonant with the closed prerogative system of Article 144(3) and with the rule of law requirements of constitutional enumeration.

The primary constitutional instrument through which the guardian function is exercised within the ordinary framework of presidential competences is the referral to the TK, enabling the President to raise constitutional objections through an institutionally authorised channel and to secure a legally binding resolution of constitutional doubt by the organ specifically designated for this purpose. This mechanism operationalises the guardian function within the rule of law: rather than acting unilaterally upon the President's own constitutional assessment, referral to the TK invokes the adjudicatory authority of an independent tribunal and produces a binding determination that governs the further fate of the contested normative act. The integrity of the mechanism depends, however, upon the institutional independence of the TK itself — which, as the events of 2015 demonstrated, cannot be treated as a structural given immune to political challenge from actors holding governmental authority.

The synthesis of the competence architecture examined across this chapter reveals a constitutional design of coherent internal logic. The President of the Republic of Poland occupies a position defined by a combination of autonomous prerogatives, participatory powers in the legislative and foreign policy domains, structurally durable appointment influence, constitutionally constrained emergency authority, and an open-textured guardian mandate. This combination is calibrated to the conception of the presidency as a balancing and corrective institution within a parliamentary constitutional order — sufficiently powerful to function as a genuine counterweight in moments of institutional dysfunction, yet constitutionally constrained from accumulating the authority that would transform the office into a competing executive centre of gravity. The modalities through which successive presidents have exercised — or declined to exercise — these competences in practice constitute the empirical subject of the chapter that follows.

Chapter 3. Presidential Practice and the Exercise of Arbiter Functions in the Third Republic of Poland

3.1. Methodological Approach to the Empirical Analysis of Presidential Conduct

The preceding chapters established the constitutional foundations and competence architecture of the Polish presidency. The task of the present chapter is to assess how successive occupants of the office exercised — or declined to exercise — those competences in practice, and to evaluate the extent to which each presidency realised, approximated, or departed from the model of constitutional arbiter.^{[15, s. 191]} This assessment requires a coherent analytical framework grounded in observable conduct rather than in normative presumption, capable of generating evaluative conclusions with sufficient methodological transparency to withstand critical scrutiny.

The methodological approach adopted in this chapter combines a diachronic case-study design with systematic application of three operational criteria derived from the theoretical framework elaborated in Chapter 1. The case-study design is justified by the nature of the empirical object: the exercise of presidential power is constituted by discrete decisions taken in specific institutional contexts, and the causal logic connecting each decision to its structural conditions cannot be adequately captured by aggregative methods alone. Periodisation follows the boundaries of presidential terms, which represent the primary unit of analysis. Five presidencies are examined in sequence: Lech Wałęsa (1990–1995), Aleksander Kwaśniewski (1995–2005), Lech Kaczyński (2005–2010), Bronisław Komorowski (2010–2015), and Andrzej Duda (2015–2025). The three operational criteria applied to each presidency are: impartiality in the exercise of constitutional competences (the absence of systematic partisan alignment in vetoes, appointments, and TK referrals); the stabilising function (the tendency to resolve rather than exacerbate inter-institutional conflicts); and constitutional guardianship (the consistent and principled defence of constitutional norms and institutions).

Several methodological challenges attend this analysis. The distinction between deliberate partisan conduct and genuine constitutional conviction is rarely unambiguous; presidents routinely justify contested decisions in constitutional terms, and the sincerity of that justification is not directly observable. The risk of anachronistic evaluation — measuring early presidencies against standards of constitutional maturity that only later became articulate — is addressed by calibrating expectations to the constitutional conditions prevailing at each period. A comparative dimension is also incorporated: as the scholarly analysis of disputes surrounding presidential powers in post-communist states demonstrates, the propensity for constitutional ambiguity to generate presidential overreach is a structurally conditioned, not merely individual, phenomenon — disputes concerning presidential powers arise not from theoretical reflection but from the practical decisions of presidents who interpret their powers as granting discretion rather than imposing obligation. ^[7]

3.2. The Presidency of Lech Wałęsa (1990–1995): Conflict, Ambition, and the Limits of Arbitration

The presidency of Lech Wałęsa may be characterised, without polemical intent, as a paradigmatic instance of presidential activism in conditions of acute constitutional ambiguity. The institutional context in which Wałęsa operated was profoundly inhospitable to the arbiter model: the constitutional order of the early Third Republic rested upon the amended 1952 Constitution and, from 1992, the so-called Small Constitution, neither of which resolved with precision the boundaries between presidential and governmental authority.^{[16, s. 27]} The absence of clear demarcation lines was not merely a technical deficiency; it created structural opportunities for institutional conflict that an assertive president was constitutionally positioned to exploit.

The character of the coalition governments of this period supplied a further background condition. Since 1991, majority coalition government has been the dominant form of executive organisation in Poland, a consequence of the fragmented and relatively unstable party system that characterised the post-communist transition; out of twenty cabinets formed by that period, seventeen were of coalition character, and the average duration of a government was notably brief. ^{[9, s. 147]} During the Wałęsa years, this brevity generated a pattern of governmental instability that both incentivised and provided opportunities for presidential intervention. The governments of Hanna Suchocka and Waldemar Pawlak provided the immediate institutional counterparts against which Wałęsa's activist conduct was measured.

The specific episodes that define the Wałęsa presidency in relation to the arbiter criteria are numerous. The disputed assertion of presidential authority over the so-called „presidential ministries” — the Ministries of National Defence, Internal Affairs, and Foreign Affairs — constituted a claim to executive co-determination that found no unambiguous constitutional basis. The dismissal of the Minister of National Defence without adequate inter-institutional consultation illustrated the practical consequences of this posture. The presidential veto of the state budget law was widely interpreted as a partisan intervention at a moment of governmental fragility rather than a constitutionally grounded exercise of the corrective function. The public invocation of the presidential power to dissolve parliament in politically charged circumstances further undermined the stabilising character of the presidency.

Evaluated against the three operational criteria, the Wałęsa presidency registers unfavourably on each count. On impartiality, the alignment of presidential intervention with moments of political vulnerability of particular governments, rather than with clear constitutional violations, is difficult to reconcile with the requirements of non-partisan conduct. On the stabilising function, the preponderance of evidence suggests that presidential activism prolonged and exacerbated inter-institutional conflicts rather than resolving them. On constitutional guardianship, the invocation of constitutional authority in support of politically motivated interventions amounted to distortion rather than vindication of the guardian mandate. A structural qualification is nonetheless necessary: as comparative analysis of presidential power suggests, all three presidents who held office in the Czech Republic since 1993 treated their powers as a right rather than an obligation, confirming that the discretionary interpretation of presidential competences is a structurally conditioned rather than merely individual phenomenon. ^[7] The Wałęsa case accordingly reveals the systemic consequences of constitutional under-determination as much as it evidences individual deviation.

Assertion of presidential authority over the defence, internal affairs, and foreign affairs ministries without clear constitutional foundation.
Unilateral dismissal of the Minister of National Defence, contesting the principle of governmental responsibility for ministerial appointments.
Veto of the state budget law in politically sensitive circumstances, raising the question of partisan rather than constitutional motivation.
Public invocation of the dissolution power during governmental instability, undermining the stabilising character of the presidential function.

3.3. The Presidencies of Aleksander Kwaśniewski (1995–2005): Cohabitation and Institutional Equilibrium

The two terms of Aleksander Kwaśniewski represent, in the assessment advanced in this chapter, the closest approximation to the constitutional arbiter model observable in the Third Republic of Poland. This approximation was, however, structurally conditioned rather than purely dispositional: the institutional circumstances of cohabitation created incentive structures that rewarded presidential restraint in ways that did not uniformly obtain throughout both terms. The election of Kwaśniewski in 1995 placed a president whose political formation lay in the Democratic Left Alliance (Sojusz Lewicy Demokratycznej — SLD) in office alongside a coalition government of the same formation before the 1997 parliamentary elections produced the first experience of full cohabitation under the new constitutional framework. The governing coalition formed by the Electoral Action Solidarity (Akcja Wyborcza Solidarność — AWS) and the Freedom Union (Unia Wolności — UW) under Prime Minister Jerzy Buzek presented Kwaśniewski with a governmental majority of distinctly different political composition for the critical formative period of the 1997 Constitution.

During the cohabitation period, presidential conduct displayed characteristics broadly consistent with the arbiter model.^{[17, s. 3]} The veto power was employed with notable restraint relative to what the volume of contested legislation would have permitted an assertive president to mobilise. Presidential management of Poland's accession candidacies to NATO and the European Union demonstrated the capacity of the office to function as a supra-partisan institutional actor representing national rather than factional interests. The referral of legislative acts to the TK was exercised within the bounds of genuine constitutional doubt rather than deployed systematically as a mechanism of political obstruction.

The dynamics of the second term diverged from this pattern in significant respects. The return of a left-aligned government after the 2001 parliamentary elections diminished the structural incentives for restraint that cohabitation had supplied. Appointment decisions during this period attracted criticism as insufficiently attentive to criteria of independence and professional competence. The Rywin affair of 2002, while not directly implicating presidential conduct, cast a shadow over the political formations most closely associated with the presidency and raised systemic questions about governance norms. The second term's record on impartiality and the stabilising function is accordingly more ambiguous than that of the cohabitation period.

The analytical significance of the Kwaśniewski presidencies lies in the structural demonstration they provide. The contextually conditioned character of arbitration during these terms suggests that presidential compliance with the normative requirements of the role depended substantially upon political incentives generated by institutional configuration — specifically, by the presence or absence of cohabitation — rather than upon a consistent and principled disposition. As the evolution of presidential legislative activity in Poland demonstrates at the level of legislative initiative, the real boundaries of presidential conduct have been determined by the political balance of power rather than by constitutional norms or doctrinal calls for restraint, and no president has consistently applied self-limitation advocated in the scholarly literature. ^[8] The Kwaśniewski case confirms this structural pattern: the arbiter model was most faithfully approximated precisely when structural conditions made its adoption strategically rational.

3.4. The Presidencies of Lech Kaczyński and Bronisław Komorowski (2005–2015): Polarisation and the Boundaries of Presidential Neutrality

The decade spanning the presidencies of Lech Kaczyński and Bronisław Komorowski represents a period during which accelerating political polarisation placed the structural assumptions of the arbiter model under conditions of intensifying stress. The two presidencies offer sharply contrasting approaches to the exercise of constitutional competences, yet both — by different mechanisms — illuminate the constraints that a polarised party system imposes upon the realisation of the presidential arbiter role.

The presidency of Lech Kaczyński (2005–2010) was conducted under the ideological premise of what his political formation, Prawo i Sprawiedliwość (PiS — Law and Justice), termed the construction of a „Fourth Republic” — a renovation of the constitutional order premised upon the identification of systemic distortions requiring institutional disruption. This ideological commitment shaped presidential conduct from the outset. The frequency of the legislative veto increased substantially after the formation of the government led by Civic Platform (Platforma Obywatelska — PO) under Donald Tusk in 2007, generating sustained inter-institutional conflict. The dispute over the ratification of the Lisbon Treaty and the question of the authority competent to represent Poland at European Council meetings — arising from divergent interpretations of Article 133 of the Constitution — constituted a prominent episode with implications for Poland's standing within the European Union. Appointment decisions during this presidency were widely regarded by political and scholarly commentators as insufficiently attentive to the requirements of non-partisan selection.

The presidency of Bronisław Komorowski (2010–2015), by contrast, was conducted in a self-consciously restrained mode. The legislative veto was employed with notably low frequency, and the character of appointments was generally regarded as more attentive to professional criteria than in the preceding term. Management of foreign policy competences, including national security matters, proceeded without the inter-institutional disputes that had marked the Kaczyński presidency. However, the Komorowski presidency attracted a distinct category of criticism: precisely because political polarisation had intensified, presidential restraint was interpreted by sections of political and scholarly opinion as amounting to a failure of constitutional guardianship. The argument was advanced that, in conditions of acute inter-institutional conflict, presidential silence amounts to passive alignment with the governmental majority, enabling constitutional erosion to proceed without check.

Taken together, these two contrasting presidencies disclose a structural dilemma inherent in the arbiter model under conditions of intense political polarisation. As the comparative study of presidential power in post-communist states suggests, presidential activism most often generates discussion and proposals for the limitation of presidential powers, whereas restraint risks reinterpretation as political complicity. ^[7] Both modes of presidential conduct are thus rendered structurally problematic under polarisation: assertiveness produces partisan identification, and restraint produces allegations of passive complicity. The arbiter model presupposes a degree of political consensus about constitutional norms that polarisation systematically erodes.

The Kaczyński presidency employed the legislative veto with substantially greater frequency against the Tusk government, generating sustained inter-institutional conflict inconsistent with the stabilising function.
The dispute over European Council representation illustrated the capacity of presidential conduct in the foreign policy domain to generate constitutional controversy with external ramifications.
The Komorowski presidency adopted an explicitly restrained posture characterised by low veto rates and reduced inter-institutional friction.
Criticism of Komorowski's restraint raised the structural question of whether presidential neutrality in polarised conditions amounts to a form of default alignment with the governmental status quo, and thus itself a departure from the guardianship criterion.

3.5. The Presidency of Andrzej Duda (2015–2025): Presidential Partisanship and the Crisis of Constitutional Arbitration

The presidency of Andrzej Duda (2015–2025) constitutes the most sustained and institutionally consequential departure from the constitutional arbiter model documented in this chapter. It provides the most direct empirical test of the central thesis that the realisation of the arbiter role is contingent upon political will rather than upon constitutional mechanisms alone. The decade of the Duda presidency generated a pattern of conduct that systematically deployed the constitutional competences of the office in the service of a partisan political project, with consequences for the constitutional order extending well beyond any individual episode.

The onset of the constitutional crisis of 2015–2016 placed the guardian function under immediate and acute pressure. The refusal to administer the constitutional oath to three judges of the TK who had been validly elected by the preceding Sejm, combined with the administration of the oath to five judges elected by the incoming Sejm under procedurally contested circumstances, constituted a decision of fundamental constitutional moment. It effectively transferred the controlling majority within the TK to judges whose selection was associated with the governing PiS formation, with the consequence that the TK ceased, for a substantial period, to function as an independent adjudicatory body capable of reviewing legislative acts against constitutional standards. The institutional significance of this intervention can scarcely be overstated: it paralysed precisely the organ designated by the constitutional design to serve as authoritative interpreter of constitutional norms, and it did so through a presidential decision taken at the moment when TK review was of maximum political relevance.

The exercise of the legislative veto over the decade of the Duda presidency provides perhaps the most direct empirical evidence of partisan rather than constitutional motivation. During the period 2015–2023, in which PiS-led governments commanded a parliamentary majority, presidential vetoes were exercised with a frequency standing in marked contrast to the volume of contested legislation enacted during that period. Substantially more frequent veto deployment occurred only in relation to legislation associated with the governmental agenda of the coalition under Donald Tusk that took office following the parliamentary elections of October 2023. The asymmetry between the treatment of legislation associated with the two successive governments — one aligned with the President's political formation and one in sharp opposition — constitutes, within the analytical framework of this chapter, direct evidence against the impartiality criterion. As the analysis of the presidential legislative initiative in Poland demonstrates, no president has consistently applied the doctrinal self-restraint advocated in the literature, and the real boundaries of presidential conduct have been set by the political balance of power rather than by constitutional norms. ^[8] The Duda presidency does not constitute an exception to this structural pattern; it constitutes its most extreme empirical instantiation.

The appointment domain similarly reflected the pattern identified under the impartiality criterion. The composition of the National Council of the Judiciary (Krajowa Rada Sądownictwa — KRS), the Supreme Court (Sąd Najwyższy — SN), and the TK was substantially altered through appointment decisions that departed from the conventions of independence and professional standing that had previously informed such choices. The legal status of certain of these appointments became the subject of ongoing controversy both within the Polish domestic constitutional order and in the jurisprudence of the Court of Justice of the European Union, generating a prolonged conflict between the executive and judicial branches with no clear constitutional resolution.

The period of cohabitation following the October 2023 elections represented the concluding phase of the Duda presidency and provided a further test of the arbiter hypothesis under reversed political circumstances. During this period, the President employed the veto power, TK referrals submitted to a tribunal of contested composition, and the refusal to promulgate enacted legislation with a frequency and systematicity that contrasted sharply with the preceding alignment period. The systemic implications extend beyond the enumeration of individual episodes. As the scholarly study of the presidential legislative initiative confirms, each holder of the presidential office acts within the freedom granted directly by the Constitution when choosing a model of conduct — and that freedom, when exercised without the discipline of political incentives favouring restraint, can transform the instruments of constitutional correction into instruments of partisan obstruction. ^[8] The Duda presidency demonstrated, with a clarity unavailable from any preceding term, that the constitutional design of 1997 lacks enforceable mechanisms capable of compelling presidential impartiality.

Episode	Period	Constitutional Domain	Criterion Affected	Analytical Significance
Refusal to administer oath to three validly elected TK judges	2015	Guardianship / Appointment	Guardianship; Impartiality	Direct obstruction of constitutional organ independence
Administration of oath to five judges of contested election	2015	Appointment; TK composition	Impartiality; Guardianship	Transfer of TK majority to PiS-aligned formation

Extensive vetoes and TK referrals against Tusk government	2023–2025	Legislative process; TK referral	Impartiality; Stabilising function	Asymmetric deployment of corrective instruments under cohabitation

The partisan asymmetry in the exercise of the legislative veto across the two phases of the Duda decade constitutes direct empirical evidence against the impartiality criterion.
The manipulation of TK composition through selective oath administration and contested appointments eliminated the institutional precondition for independent constitutional review.
Systematic restructuring of the KRS and SN raised unresolved questions about the independence of judicial oversight institutions within the domestic constitutional order.
The cohabitation period of 2023–2025 confirmed that the frequency of presidential intervention is determined by political alignment rather than by the constitutional character of the legislation in question.
The Duda presidency demonstrates that the dependence of the constitutional arbiter role upon individual political will is sufficient to render the role substantially inoperative in the absence of that will — with consequences beyond the power of the existing constitutional order to remedy unilaterally.

The central conclusion of this chapter is that the five presidencies examined provide convergent empirical support for the thesis elaborated in Chapter 1 and the constitutional analysis of Chapter 2. The structural conditions — the character of the coalition government system, the presence or absence of cohabitation, the degree of political polarisation — have influenced the incentive structures within which individual presidents have operated. The Kwaśniewski cohabitation period demonstrates that structural incentives can induce arbiter-consistent conduct even in the absence of a stable dispositional commitment. However, as the Duda presidency confirms with particular force, these structural conditions are insufficient, in the absence of enforceable constitutional mechanisms, to guarantee the conduct that the arbiter model requires. The Constitution of 1997 created a presidency constitutionally designed for arbitration but institutionally incapable of compelling it — a conclusion to which the totality of the empirical evidence examined in this chapter points with consistency.

Conclusion

The present dissertation has sought to interrogate a foundational question of Polish constitutional scholarship: whether the President of the Republic of Poland, as designed by the Constitution of 1997 and as observed in the political practice of the Third Republic, fulfils the function of political arbiter in any institutionally meaningful sense. The central thesis advanced throughout this work holds that the constitutional architecture of the Polish presidency creates a normative framework consistent with the arbiter model, yet simultaneously fails to provide the institutional mechanisms necessary to render that model compulsory.^{[18, s. 200]} Arbitration, it has been argued, is thus in Poland a dispositional possibility rather than a structural certainty — a function that may be performed when individual presidential will and systemic incentives align, but one that cannot be enforced when they diverge.

The first chapter established the theoretical foundations upon which the remainder of the analysis rested. The concept of political arbitration was traced to Benjamin Constant's formulation of the pouvoir neutre — a fourth power standing above the tripartite division of executive, legislative, and judicial authority, charged with maintaining systemic equilibrium without itself participating in the ordinary contests of government. ^[1] Three analytically distinct criteria for arbiter conduct were identified: impartiality with respect to partisan competition, a stabilising orientation directed toward constitutional equilibrium, and a commitment to constitutional guardianship that transcends momentary political calculation. The arbiter was distinguished from two adjacent but conceptually different presidential roles — the constitutional guardian in the strict Kelsenian sense, whose function is adjudicative rather than political, and the symbolic figurehead, whose role is ceremonial and devoid of substantive authority. ^[2] Poland's constitutional arrangement was located within the comparative typology of democratic systems as a rationalised parliamentary system retaining residual semi-presidential features — a classification that carries direct implications for the presidency, since it establishes the institution as constitutionally subordinate in the ordinary conduct of government yet constitutionally empowered to intervene at moments of systemic stress. Article 126 of the Constitution was identified as the textual locus of the arbiter concept, investing the presidency with a mandate expressed in terms sufficiently general to sustain widely divergent interpretations. The organising analytical tension of the dissertation — the gap between constitutional design and constitutional practice — was thereby established at the outset.

The second chapter conducted a systematic analysis of the presidential competence architecture as constituted by the 1997 Constitution. Presidential prerogatives enumerated under Article 144(3) were identified as the constitutional infrastructure of presidential neutrality, since they operate without ministerial countersignature and therefore represent moments at which individual presidential judgment is formally insulated from governmental mediation. Among the competences examined, the suspensive veto provided under Article 122 emerged as the most visible instrument of presidential correction, functioning as a legislative checkpoint capable of slowing legislative processes that the President regards as constitutionally suspect or politically destabilising. However, it was observed that the veto's consistency with the arbiter model depends entirely upon the motivational conditions governing its deployment: a veto exercised in the service of constitutional principle performs a genuinely arbitral function, while a veto deployed in the service of partisan interest constitutes an abuse of the instrument. The foreign and security policy competences established under Articles 133 and 134 were found to create structurally overlapping authority between the presidency and the Council of Ministers — a zone of constitutionally ambiguous jurisdiction that functions as a persistent source of inter-institutional conflict, particularly under conditions of cohabitation. Appointment powers — extending across the judiciary, the National Bank, regulatory bodies, and elements of the military command — were assessed as the most structurally durable form of presidential influence, since they shape the institutional landscape of the state over periods that extend well beyond any individual government's tenure. The guardian clause of Article 126(2) was characterised as an open-textured mandate — one that invests the presidency with an overarching constitutional responsibility while leaving the modalities of its exercise to individual presidential determination. The conclusion of the second chapter was that the Constitution creates a presidency normatively designed for arbitration but deliberately underspecifies the mechanisms by which that design is to be realised.

The third chapter turned from constitutional text to constitutional practice, examining through five empirical case studies the manner in which successive holders of the presidential office have exercised — or failed to exercise — the arbiter function. The presidency of Lech Wałęsa was found to have failed all three arbiter criteria: the politics of the early 1990s were characterised by sustained presidential efforts to expand executive authority at the expense of parliamentary government, with constitutional ambiguity instrumentalised in an expansionist rather than a moderating direction. ^[5] The Aleksander Kwaśniewski presidency, extending across two terms from 1995 to 2005, represented the closest historical approximation to the arbiter model, particularly during the period of cohabitation with the government of Jerzy Buzek. The Kwaśniewski experience demonstrated that structural incentives — specifically, the political logic of cohabitation, which aligns presidential interest with the role of institutional moderator — can induce conduct consistent with the arbiter model even in the absence of a stable dispositional commitment to neutrality. Lech Kaczyński's presidency from 2005 to 2010 was marked by extensive deployment of the suspensive veto during the period of cohabitation with the government of Donald Tusk, raising substantive questions concerning the partisan rather than constitutional motivation for presidential intervention. ^[6] Conflicts over the constitutional demarcation of foreign policy authority under Article 133 illustrated with particular clarity the structural tension created by the Constitution's overlapping competence architecture. The Bronisław Komorowski presidency offered a restrained model characterised by a low rate of legislative veto and a generally deferential posture toward parliamentary government; yet this restraint attracted criticism from the opposing direction, with the assessment that constitutional guardianship obligations were insufficiently discharged in the face of mounting institutional tensions during the 2013–2015 period. The presidency of Andrzej Duda, covering the decade from 2015 to 2025, was assessed as the most sustained and systematic departure from the arbiter model in the history of the Third Republic. ^[7] The Constitutional Tribunal crisis of 2015 and 2016 constituted a paradigm case of presidential facilitation of constitutional destabilisation rather than its prevention: presidential conduct during this episode accelerated the breakdown of judicial independence rather than arresting it. The observable asymmetry between near-zero vetoes against successive governments of the Law and Justice party and extensive vetoes deployed against the Tusk government formed from 2023 onwards provided direct empirical evidence of partisan rather than constitutional motivation in the exercise of the most visible presidential corrective instrument. ^[8]

The principal conclusions that may be drawn from the foregoing analysis are four in number. First, the Polish Constitution of 1997 succeeds in creating a normative framework consistent with the concept of presidential arbitration as theorised in the academic literature, but it does so through a combination of open-textured provisions and residual structural ambiguity that renders the framework practically unenforceable. The arbiter function is constitutionally endorsed but not constitutionally secured. Second, structural conditions — most importantly, the configuration of cohabitation, in which the President and the Prime Minister belong to opposed political formations — exert a significant constraining influence on presidential conduct, generating incentive structures that are broadly consistent with arbiter behaviour. However, as the Duda presidency demonstrates, structural incentives are neither necessary nor sufficient conditions for arbiter conduct: a President disposed toward partisan maximisation will exploit even cohabitation conditions to pursue adversarial rather than mediating strategies. Third, the appointment powers of the presidency, by virtue of their temporal reach, have proven more consequential for constitutional equilibrium than the formally prominent veto instrument. Presidential appointments to the Constitutional Tribunal, the Supreme Court, and analogous institutions have in certain periods functioned as mechanisms for the consolidation of partisan advantage rather than the maintenance of institutional balance. Fourth, and most broadly, the empirical record of the Third Republic suggests that the arbiter function is structurally available to the Polish presidency but historically exceptional in its realisation: the Kwaśniewski cohabitation period constitutes the clearest positive case, and its positive character is substantially attributable to conjunctural factors rather than to institutional design.

The Polish case carries implications for the broader theoretical literature on presidential arbitration and semi-presidential government. The Constantian model of the pouvoir neutre, as received and elaborated in contemporary constitutional scholarship, tends to presuppose a degree of institutional insulation — structural guarantees of presidential independence from partisan logic — that the Polish constitutional framework does not provide. ^[1] Where the arbiter is elected by direct popular mandate, as in Poland, the President possesses a democratic legitimacy that is both the source of institutional authority and a persistent temptation toward partisan self-assertion. The Polish experience thus qualifies the theoretical model by demonstrating that democratic legitimacy and arbitral neutrality exist in structural tension: the former provides the political resources that make effective arbitration possible, while simultaneously generating incentives that make it difficult to sustain. Furthermore, the dissertation lends empirical support to the theoretical proposition that the arbiter model functions most reliably when it is reinforced by systemic incentives rather than left to individual presidential disposition alone. ^[2] The comparative lesson that emerges is not that the arbiter presidency is theoretically incoherent but rather that it requires institutional reinforcement — through appointment procedures, conflict-resolution mechanisms, and constitutional review — if it is to function with any consistency across different personality types and political configurations.

The normative implications of the analysis deserve separate consideration. If the Polish constitutional order is to develop the presidency into a genuinely effective arbiter institution, several conditions would need to be satisfied that are not presently met. The competence architecture would benefit from greater precision in the demarcation of concurrent authority between the President and the Council of Ministers, particularly in the domains of foreign policy and national security, where the ambiguity of the existing provisions has repeatedly generated conflict rather than structured coordination. ^[4] The appointment powers of the presidency might profitably be subjected to more robust procedural constraints — including supermajority requirements or cross-partisan confirmation procedures — so as to diminish the potential for their use as instruments of institutional capture. Most fundamentally, the question of motivational alignment requires institutional attention: if the arbiter function is to be performed reliably rather than occasionally, the constitutional system must create conditions under which presidential self-interest — electoral, reputational, and political — more consistently coincides with arbiter-consistent conduct. The design of such conditions is a problem of institutional architecture that lies beyond the scope of the present dissertation, but the empirical record reviewed in Chapter Three provides ample evidence that the present architecture does not solve it. ^[9] It may also be observed that informal norms and constitutional conventions — the accumulated expectations that give constitutional provisions their practical meaning — are themselves products of presidential practice over time. The development of a robust convention of presidential neutrality would represent a significant structural contribution, but conventions of this kind presuppose a period of sustained arbiter conduct of a length and consistency that the history of the Third Republic has not yet produced.

The question of the presidency as political arbiter is, finally, not merely an academic question about the proper classification of a constitutional institution. It is a question about the conditions under which democratic constitutional orders are sustained over time. The Constitution of 1997 was constructed in the conviction that democratic consolidation required, among other things, a presidentially mediated mechanism of systemic stabilisation — an institution capable of interrupting pathological political cycles before they could destabilise constitutional normality. ^[3] The experience of the decade from 2015 to 2025 demonstrated that this mechanism can fail, not through constitutional inadequacy alone, but through the convergence of institutional ambiguity with presidential disposition hostile to the neutrality that the arbiter role presupposes. The significance of this failure extends beyond the Polish case. In a period of democratic backsliding across Central and Eastern Europe, the Polish experience offers a detailed case study of how presidentially facilitated institutional erosion can proceed within the formal framework of a constitution that contains no explicit authorisation for it — precisely because the open texture of presidential mandates permits their reinterpretation in directions inconsistent with constitutional purpose. ^[8] This observation does not counsel pessimism about the prospects of constitutional democracy in Poland; it counsels institutional realism about the conditions under which presidential arbitration, as a stabilising constitutional function, can be expected to perform. The arbiter presidency, the present dissertation concludes, remains a constitutional possibility — and perhaps, in the long arc of democratic development, a constitutional aspiration — but it will remain no more than a possibility until the institutional conditions for its realisation are more deliberately and more durably constructed.
