TheChamber of Deputies (Spanish:Cámara de Diputados) is thelower house of thePlurinational Legislative Assembly ofBolivia. The composition and powers of this house are established in thePolitical Constitution of the State. The session room is located in the Legislative Palace building inPlaza Murillo.
Deputies serve five-year terms, and must be aged at least 25 on the day of the election.
The Chamber of Deputies comprises 130 seats (including the seven special seats), elected using aseat linkage based mixedcompensatory system using a two votes: 63 deputies are elected byfirst-preference plurality to represent single-memberelectoral districts, 60 are elected byclosed listparty-list proportional representation from party lists on a departmental basis (in districts of varying sizes corresponding to Bolivia's nine departments with a threshold of 3%).[1] The list seats in each region are awarded proportionally based on the vote for the presidential candidates, subtracting the number of single-member districts won (to providemixed-member proportional representation). The remaining seven seats are reserved indigenous seats elected by theusos y costumbres. A voter can only vote in one of either the normal constituencies or special constituencies (coexistence).
The election uses the same votes as the votes for the President and the Senate, making it adouble (triple) simultaneous vote. Voters may therefore notsplit their ticket between these elections, but they may vote for a candidate of a different list in the election of the Chamber as the deputies from the single-member districts are elected using separate votes.
Party lists are required to alternate between men and women, and in the single-member districts, men are required to run with a female alternate, and vice versa. At least 50% of the deputies from single-member districts are required to be women.
