Legislative attempts to draw new districts failed, as Republican governor Pete Wilson vetoed all three plans made by the Democratic-controlled state legislature.

In September 1991, the Supreme Court of California took over the redistricting process to break the stalemate and, under its direction, a panel of retired judges determined the boundaries of the new districts.

It was mutually decided by legislators that the status quo in terms of balance of power would be preserved - a so-called Incumbent Protection Plan.

The California Citizens Redistricting Commission certified final district maps on August 15, 2011, and they took effect with the 2012 election.

The names of the remaining applicants were submitted to the California State Auditor, who randomly drew three Democrats, three Republicans, and two from neither of those parties.

This referendum period ended on March 27, 2022, when the filing and campaign season for the 2022 primary election was already underway.
