Case Information

A federal challenge to the new congressional map ratified by Proposition 50, alleging the unconstitutional predominant and unjustified use of race.

On Jan. 14, 2026, the court denied a preliminary injunction, finding that the plaintiffs failed to prove that race predominated in drawing the district lines; that decision has been appealed to the U.S. Supreme Court.
