Parliament of Belgium is the bicameral federal legislature of the Kingdom of Belgium, created by the Constitution of 1831 and seated at the Palace of the Nation in Brussels. The institution consists of two chambers with distinct compositions and competences: a directly elected lower chamber and a partially renewed upper chamber that reflects regional and community representation. It operates within the framework established by the Belgian Constitution and the federal reforms following the Belgian state reforms of the late 20th century.
The origins trace to the aftermath of the Belgian Revolution (1830) and the inaugural Constituent National Congress (1830–1831), which produced the Belgian Constitution of 1831 establishing a bicameral legislature. In the 19th century the Belgian Liberal Party, Belgian Catholic Party, and Belgian Workers' Party dominated successive parliaments, while events such as the School Wars and the World War I occupation influenced parliamentary politics. Post-World War II reconstruction and the rise of parties like Christian Social Party (Belgium), Belgian Socialist Party, Party for Freedom and Progress, and later regional parties such as Flemish Block, New Flemish Alliance, and Socialist Party (Wallonia) drove federalization. Constitutional revisions in 1970, 1980, 1988–89, 1993 and 2001 gradually devolved powers to Flanders, Wallonia, and the Brussels-Capital Region, reshaping parliamentary competences and altering the role of the Senate (Belgium).
The legislature comprises the Chamber of Representatives (Belgium) with 150 members and the Senate (Belgium) with 60 members after the sixth state reform. The Chamber's deputies are elected from multi-member constituencies corresponding to provinces and the Brussels-Capital Region under the D'Hondt method of proportional representation; parties include Vooruit (party), Open Flemish Liberals and Democrats, Christen-Democratisch en Vlaams, DéFI, and Vlaams Belang. The Senate consists of community and regional representatives: community senators appointed by the Flemish Parliament, Parliament of the French Community, Parliament of the German-speaking Community, regional senators from the Parliament of Wallonia and Brussels Parliament, plus co-opted senators. Parliamentary leadership includes the Presidents of the Chamber and the Senate; notable historical presiding officers include Charles Rogier and Paul-Henri Spaak.
Constitutionally the Chamber holds primary legislative initiative and final vote on confidence in the Federal Government (Belgium), budgets and taxation, while the Senate serves as a meeting chamber for the federated entities and reviews constitutional and institutional matters. Exclusive competences involve the ratification of international treaties by the Chamber, approval of the federal budget, and motions of confidence and no confidence affecting the Prime Minister of Belgium and cabinets formed by figures such as Guy Verhofstadt and Elio Di Rupo. The Senate retains competence over constitutional revision procedures involving the Kingdom of Belgium's institutional arrangements and participates in appointments to high state offices including judges of the Court of Cassation (Belgium) and members of the Constitutional Court (Belgium).
Bills originate with deputies, ministers or citizen initiatives and proceed through committee scrutiny in the Chamber, public readings and plenary votes, following procedures codified in the Belgian Constitution and parliamentary rules. Ordinary legislation generally requires passage by the Chamber alone; however, special laws affecting the structure of the state, language use or institutional competencies require a qualified majority and involvement of the Senate in the revision and special-majority procedure. After parliamentary approval, bills are referred to the King of the Belgians for royal assent and promulgation; disputes may be adjudicated by the Constitutional Court (Belgium) if conflicts with constitutional rights or division of powers arise.
Parliament holds the government to account through motions, oral and written questions, parliamentary inquiries and interpellations; prominent inquiries have examined crises such as the Dutroux affair and security failures. The Chamber's confidence is required for formation and survival of cabinets led by figures like Charles Michel and Alexander De Croo; coalition formation often involves negotiations among parties including MR (Belgium), CD&V, sp.a, and regionalists like Ecolo. Parliament approves budgets presented by finance ministers, ratifies international agreements negotiated by foreign ministers such as Didier Reynders, and may compel resignation through votes of no confidence.
Members of the Chamber are elected by universal suffrage using proportional representation with open lists in constituencies aligned with provinces and Brussels-Capital Region; voters may split their ballot among candidates of parties like PVDA-PTB or Humanist Democratic Centre. Senate members are appointed by regional parliaments and co-opted according to party performances at federal elections, reflecting the federal character established after reforms such as the Sixth Belgian State Reform (2011) and earlier reforms. Language groups—Dutch-speaking, French-speaking, and German-speaking—are represented institutionally; linguistic parity and electoral thresholds influence coalition arithmetic in bodies such as the Flemish Parliament and Parliament of Wallonia.
Parliamentarians enjoy parliamentary immunity protecting freedom of speech in parliamentary proceedings, grounded in the Belgian Constitution; disciplinary rules and parliamentary ethics codes regulate conduct. Legal immunity can be lifted by the Chamber or Senate to permit prosecution, as seen in proceedings against MPs from parties such as Vlaams Belang and allegations surrounding individual members. Transparency obligations include declaration of financial interests, committee hearings, and oversight by bodies like the Court of Audit (Belgium); accountability mechanisms encompass interpellations, votes of no confidence, and judicial review by the Constitutional Court (Belgium).
