The California Citizens Redistricting Commission is the redistricting organization for the state of California. It is responsible for determining the boundaries for the Senate, Assembly, and Board of Equalization districts in the state. The 14-member commission consists of five Democrats, five Republicans, and four commissioners from neither major party. The commission was authorized following the passage of California Proposition 11, the Voters First Act, by voters in November 2008. The commissioners were selected in November and December 2010 and were required to complete the new maps by August 15, 2011.
Following the 2010 passage of California Proposition 20, the Voters First Act for Congress, the Commission was also assigned the responsibility of redrawing the state's U.S.congressional district boundaries in response to the congressional apportionment necessitated by the 2010 United States Census. The Commission has faced opposition from politicians because "many safe seats in the Legislature could suddenly become competitive."
The Commission certified new electoral district maps by the August 15, 2011 deadline with the required “supermajority” of a minimum of three Democrats, three Republicans, and three commissioners from neither major party, as stipulated by Article XXI sections 2(c) and 2(g) of the California Constitution. Maps for the state legislative districts passed with a 13-1 vote, and for Congressional districts with a 12-2 vote. In response to a series of legal challenges, the California Supreme Court ruled unanimously three times in favor of the Commission’s maps, finding them in compliance with the U.S. Constitution and California Constitution. In addition, the U.S. Department of Justice granted preclearance of the Commission’s maps under Section 5 of the federal Voting Rights Act. The new districts took effect for the June 5, 2012 primary. Republican sponsors put a referendum on the Senate map on the November 6, 2012 ballot as Proposition 40, but have since reversed their position and are no longer opposing the new districts.
