Senado de la República

The Senado de la República is the Upper Chamber of Mexico's federal Congress, which also includes the Chamber of Deputies. The Constitution provides for 128 senators. Each state and Mexico City elect two majority senators and return one seat for the leading minority. A further 32 senators are chosen through a national proportional list. The whole chamber is renewed every six years. [Constitution, Articles 50 and 56](https://www.diputados.gob.mx/LeyesBiblio/pdf/CPEUM.pdf).

For legislation requiring both chambers' approval, a bill passes from its originating chamber to the other for discussion and a vote. When both approve it, the text goes to the executive for publication, subject to the constitutional process for objections. These arrangements give the Senate a legislative role alongside the representation of states and The National electorate. [Constitution, Article 72](https://www.diputados.gob.mx/LeyesBiblio/pdf/CPEUM.pdf).
