Argentine Chamber of Deputies

It has 257 seats and one-half of the members are elected every two years to serve four-year terms by the people of each district (23 provinces and the Autonomous City of Buenos Aires) using proportional representation, D'Hondt formula with a 3% of the district registered voters threshold, and the following distribution:

Individuals elected to congress must be at least twenty five years old with at least four years of active citizenship and it has to be naturalized in the province that is being elected to or at least have two years of immediate residency in said province. (Art. 48 of the Argentine Constitution).

The Chamber of Deputies was provided for in the Constitution of Argentina, ratified on May 1, 1853. Eligibility requisites are that members be at least twenty-five years old, and have been a resident of the province they represent for at least two years; as congressional seats are elected at-large, members nominally represent their province, rather than a district.[1]

Otherwise patterned after Article One of the United States Constitution per legal scholar Juan Bautista Alberdi's treatise, Bases de la Constitución Argentina, the chamber was originally apportioned in one seat per 33,000 inhabitants. The constitution made no provision for a national census, however, and because the Argentine population doubled every twenty years from 1870 to 1930 as a result of immigration (disproportionately benefiting Buenos Aires and the Pampas area provinces), censuses were conducted generationally, rather than every decade, until 1947.[2]

The President of the Chamber is elected by a majority of the Chamber's members. Traditionally, the presidency is held by a member of the party or alliance of the national executive, though exceptions have occurred, such as in 2001, when the Peronist Eduardo Camaño was elected president of the Chamber during the presidency of the radical Fernando de la Rúa.[3] The officeholders for this post since 1983 have been:
