Under the current
constitution, there is no formal way to dissolve the
Federal Senate or the
Chamber of Deputies (Houses of the
National Congress).
Imperial Era In May 1823, eight months after Independence, the first brazilian legislative experience began, with the installation of the
General, Constituent and Legislative Assembly, with the task of drafting the country's first Constitution. Six months later, in confrontation with the Deputies,
Emperor Dom Pedro dissolved the assembly, ordered the arrest and exile of some deputies and created a
Council of State to draft the
Constitution, which he signed in 1824. This was the first of the eighteen times that the legislature was dissolved, the Imperial Constitution and its quasi-parliamentary model formalized the Emperor's power to dissolve the Chamber of Deputies (the Senate was not elected). During the
Regency and reign of
Dom Pedro II, the Chamber of Deputies was dissolved on several occasions, almost always when the clash between conservatives and liberals or between legislators and the reached a degree considered too high by the Emperor.
First Republic After the Proclamation of the Republic, in 1889, a Constituent Congress was convened to prepare the first republican charter, which came into force in 1891. However, on 3 November of that year, the National Congress would be closed by
President Deodoro da Fonseca, with the legislature reinstated after the attempt was deemed a coup and he resigned.
Vargas Era The legislature was closed twice by
Getúlio Vargas. After the
Revolution of 1930, as Head of the Provisional Government, Vargas dissolved the National Congress, the state legislative assemblies and the municipal chambers. Pressured by the failed
Constitutionalist Revolution, Vargas was forced to call elections for a National Constituent Assembly. On 10 November 1937, now President of the Republic elected by the same National Congress, Vargas staged a coup d'état, establishing the
Estado Novo. He closed the legislature and instituted a new, authoritarian
Constitution. Despite the new charter determining the convening of a "
National Parliament" with a appointed Federal Council and a Chamber of Deputies that could be dissolved, elections were never held.
Republican Parliamentarism During the brief parliamentary experience from 1961 to 1963 as a way to allow the inauguration of President
João Goulart under strong political and military opposition, the Additional Act to the Constitution determined that "
[v]erified the impossibility of maintaining the Council of Ministers for lack of parliamentary support, proven in motions of no confidence, consecutively opposed to three Councils, the President of the Republic may dissolve the Chamber of Deputies[...]". The then President of the Republic never exercised this attribution and the return to the presidential system stripped him of any competence to dissolve the Chamber of Deputies.
Military dictatorship During the twenty-one years of the military dictatorship (1964–1985), the National Congress was "suspended" three times.
Institutional Act No. 2 (AI-2) gave the President of the Republic the power to decree the recess of the two Houses of the National Congress, and during this period he had the prerogative to legislate. On 20 October 1966, President
Castelo Branco decreed recess for a month, to contain a "
grouping of counter-revolutionary elements" (the
1964 Coup d'Etat was considered a revolution by the military) that had formed in the legislature "
with the aim of disrupting public peace". On 13 December 1968, President
Costa e Silva issued AI-5, an institutional act that began the most repressive and violent period of the dictatorship, closing the National Congress to combat subversion and "
ideologies contrary to the traditions of our people ". The last person to decree the closure of the legislature was President
Ernesto Geisel, in 1977, through the "April package", after the National Congress rejected a constitutional amendment. Geisel alleged that the
MDB (then the opposition party on a unequal bipartisanship controlled by the military) had established a "
minority dictatorship". == Canada ==
