The National Senate was established by theArgentine Confederation on July 29, 1854, pursuant to Articles 46 to 54 of the1853 Constitution.[1] There are 72 members: three for eachprovince and three for theAutonomous City of Buenos Aires. The number of senators per province was raised from two to three following the1994 amendment of the Argentine Constitution as well as the addition of the Autonomous City of Buenos Aires' senators. Those changes took effect following theMay 14, 1995, general elections.
Senators are elected to six-year terms by direct election on a provincial basis, with the party with the most votes being awarded two of the province's senate seats and the second-place party receiving the third seat. Historically, senators wereindirectly elected to nine-year terms by each provincial legislature. These provisions were abolished in the 1994 constitutional amendment, and the first direct elections to the Senate took effect in 2001. Currently one-third of the members are elected every two years; there are no term limits.
Thevice president of the republic isex officio president of the Senate, with acasting vote in the event of a tie. In practice, theprovisional president presides over the chamber most of the time.
The Senate must obtainquorum to deliberate, this being an absolute majority. It has the power to approve bills passed by theChamber of Deputies, call for joint sessions with the lower house or special sessions with experts and interested parties, and submit bills for the president's signature; bills introduced in the Senate must, in turn, be approved by the Chamber of Deputies for their submission to the president. The Senate must introduce any changes tofederal revenue sharing policies, ratify international treaties, approve changes to constitutional or federal criminal laws, as well as confirm or impeach presidential nominees to the cabinet, the judiciary, the armed forces, and the diplomatic corps, among other federal posts.[2]
As of 2012[update] there were 24 standing committees made up of 15 members each, namely:[2]
