AB 604 California Assembly · 2025-2026 Regular Session

Redistricting: congressional districts.

Summary
The California Constitution requires the Citizens Redistricting Commission to adjust the boundary lines of the congressional, State Senate, Assembly, and State Board of Equalization districts in the year following the year in which the national decennial census is taken and requires the districts be redrawn in conformance with specified standards. This bill would specify the elements that define the congressional districts if ACA 8 of the 2025–26 Regular Session is adopted by the voters. These provisions would become operative only if specified provisions of that constitutional amendment become operative, and would remain in effect only until a new map of congressional districts is certified by the Citizens Redistricting Commission as described above. This bill would declare that it is to take effect immediately as an urgency statute.
