Mexican Constitution of 1917 |
The Congress of the Union (formally Congreso General de los Estados Unidos Mexicanos; English: General Congress of the United Mexican States) is the legislative branch of the Mexican government.
The Congress is a bicameral assembly, consisting of two chambers: the Chamber of Deputies, and the Senate of the Republic. Its structure and responsibilities are defined in the Third Title, Second Chapter, Articles 50 to 79 of the 1917 Constitution.
The upper chamber is the Senate, "Cámara de Senadores" or "Senado". It comprises 128 seats, 96 members are elected by direct popular vote for six-year terms; the other 32 seats are allocated based on proportional representation.
The lower house is the Chamber of Deputies, "Cámara de Diputados". It has 500 seats, 300 members are elected by popular vote to three-year terms; the other 200 seats are allocated according to proportional representation.
The Congress of the Union (Congreso de la Unión) has two chambers. The Chamber of Deputies (Cámara de Diputados) has 500 members, elected for a three-year term, 300 of whom are elected in single-seat constituencies by plurality, with the remaining 200 members elected by proportional representation in 5 multi-state, 40-seat constituencies. The 200 PR-seats are distributed generally without taking account the 300 plurality-seats (parallel voting), but since 1996 a party cannot get more seats overall than 8% above its result for the PR-seats (a party must win 42% of the votes for the PR-seats to achieve an overall majority).
