The Buenos Aires City Legislature (, commonly known as the Legislatura Porteña) is the legislative power of the government of the Autonomous City of Buenos Aires, Argentina. It is housed in the Legislature Palace (), an architectural landmark in the barrio of Montserrat.

History

The internecine warfare between those who favored a united Argentina with a strong central government (Unitarios) and Buenos Aires Province leaders who favored an independent nation of their own (Federales) dominated local political life in the decades following the Wars of Independence and led to the 1880 Federalization of Buenos Aires. Pursuant to this new policy, in 1882 President Julio Roca signed National Law 1260, which created the presidential prerogative of the appointment of the Mayor of Buenos Aires, as well as a city council by way of compromise towards the put-upon local gentry.

The newly formed city council (Consejo Deliberante) originally included 30 Concejales elected via male suffrage (though this excluded the city's immigrants, which made up a majority of voting-age males at least as late as 1914). The body first met during the tenure of Mayor Torcuato de Alvear, with whom a precedent for a productive relationship was established by cooperating on an unprecedented urban planning a renewal agenda. The council's resolution in 1921 for new grounds befitting a governing body of what had become one of the world's most prosperous cities was likewise approved by the Mayor at the time, José Luis Cantilo. A lot to the southwest of the Plaza de Mayo was set aside for the new building's construction, and was inaugurated on October 3, 1931.

The 1994 reform of the Argentine Constitution led to the rescission of the President's right to appoint the Mayor of Buenos Aires, and with the election of Fernando de la Rúa as the city's first directly elected mayor on June 30, 1996, an assembly was chosen for the purpose of drafting a new municipal constitution. Approved on October 1, the document created a city legislature in lieu of the city council, and increased its membership to 60 (elected for four year terms via party-list voting, as outlined in the D'Hondt method, with half the seats at stake every two years).

Overview

The body is led by the mayor's lieutenant, the Vice Chief of Government (Vicejefe de Gobierno), who acts as President of the Legislature. They are assisted by three Vice-Presidents and Parliamentary, Administrative and Coordinating Secretaries. Gabriela Michetti of the center-right Republican Proposal (PRO) party became the first disabled individual to occupy the post of President of the Legislature in 2007; she left this post ahead of the June 2009 legislative elections, where she won a seat in the Argentine Chamber of Deputies. The post is currently occupied by Vice Chief of Government Clara Muzzio of PRO.

Current composition

The following legislature was elected in the 2021 and 2023 legislative elections.
