Congresso Nacional is the bicameral legislature of the Federative Republic of Brazil, composed of two houses that enact laws, oversee executive action, and represent federative entities. It occupies a central role in Brazilian political life, interacting with institutions such as the Presidency of Brazil, the Supreme Federal Court, the Federal District (Brazil), and state legislative assemblies. The institution has been the arena for major episodes involving figures like Getúlio Vargas, Juscelino Kubitschek, Luiz Inácio Lula da Silva, Fernando Henrique Cardoso, and actors such as the Brazilian Democratic Movement, Workers' Party (Brazil), Social Democratic Party (Brazil, 2011), and Progressistas.
The legislature comprises the Federal Senate (Brazil) and the Chamber of Deputies (Brazil), reflecting federative representation and proportional representation respectively; its functions are framed by the Constitution of Brazil. Debates and decisions within the complex link to institutions and events like the Plano Real, the 1988 Brazilian Constitution, the Military dictatorship in Brazil (1964–1985), the Direct elections (Brazil), and the Impeachment of Dilma Rousseff. Interactions extend to actors such as the Attorney General of Brazil, the Federal Police (Brazil), the Superior Electoral Court, and legislative caucuses including the Bancada Ruralista.
The body's antecedents include the General Assembly of the Empire of Brazil and the Assembleia Nacional Constituinte e Legislativa; key transformations occurred with the Constitution of 1824, the Republican coup d'état (1889), and successive constitutions culminating in the Constitution of 1988. During the First Brazilian Republic, political coalitions like Coffee with milk politics shaped legislative composition; the Vargas Era centralized power, affecting legislative autonomy, while the 1967 Brazilian Constitution under the Military dictatorship in Brazil (1964–1985) modified legislative prerogatives. The re-democratization process involved actors such as Ulysses Guimarães, Tancredo Neves, and parties like the Brazilian Social Democracy Party.
The Federal Senate (Brazil) consists of representatives from each federative unit, while the Chamber of Deputies (Brazil) uses proportional lists and electoral rules administered by the Superior Electoral Court. Leadership roles include the Presidents of the Federal Senate (Brazil) and the Chamber of Deputies (Brazil), and committees such as the Constitution and Justice Committee (Brazilian Chamber of Deputies), the Budget and Finance Committee, and special investigatory panels like Parliamentary Commission of Inquiry (Brazil). Political groupings include national parties such as Brazilian Democratic Movement, Workers' Party (Brazil), Liberal Party (Brazil, 2006), Brazil Union, and regional blocs tied to governors and mayors like Paulo Câmara or João Doria.
Defined by the Constitution of Brazil, legislative powers include lawmaking in areas enumerated by the charter, oversight through instruments such as the CPI (Comissão Parlamentar de Inquérito), approval of budgetary measures tied to the Ministry of Finance (Brazil), and ratification of international agreements involving the Ministry of Foreign Affairs (Brazil). The Congresso Nacional also participates in high-level appointments, interacting with the Supreme Federal Court nomination processes and the Federal Audit Court (TCU). Legislative oversight has clashed with institutions like the Public Prosecutor's Office (Brasil) during corruption probes involving operations such as Operation Car Wash.
Bills may originate in the Chamber of Deputies (Brazil) or the Federal Senate (Brazil), with procedures governed by the Internal Rules of the Chamber of Deputies and the Regimento Interno do Senado Federal. Constitutional amendments follow procedures established for Proposed Amendment to the Constitution (PEC), requiring multiple readings and supermajorities. Budgetary legislation interacts with the National Treasury Secretariat and the Plenary of the Chamber of Deputies, while urgent measures include Provisional Measure (Brazil) instruments issued by the Presidency of Brazil. Legislative negotiation frequently involves party leaders, caucuses like the evangelical caucus (Brazil), and external actors such as governors and municipal associations.
The legislature meets at the Palácio do Congresso Nacional in Brasília, part of the Plano Piloto (Brasília) designed by Lúcio Costa and featuring works by Oscar Niemeyer. The complex includes twin towers and two domes that host the plenaries of the Federal Senate (Brazil) and the Chamber of Deputies (Brazil), situated on the Praça dos Três Poderes alongside the Palácio do Planalto and the Supreme Federal Court building. The site hosts official ceremonies with participation from presidents, ministers such as the Minister of Justice (Brazil), foreign delegations, and events linked to national anniversaries like Independence Day (Brazil).
Critiques have targeted issues including corruption scandals such as Mensalão, Operation Car Wash, and accusations involving individual deputies and senators from parties like Progressistas and Brazilian Democratic Movement. Calls for reform reference proposals for electoral system changes like open-list proportional representation, proposals to alter the Electoral Code (Brazil), and institutional reforms advocated by figures such as Sérgio Moro and Fernando Henrique Cardoso. Reform initiatives involve entities like the National Congress Budget Office and public movements including Vem pra Rua, with debates over transparency, campaign finance regulated by the Superior Electoral Court, and legislative immunity provisions related to the Constitution of Brazil.
