Overview

• California Republican lawmakers submitted a new emergency petition to the state Supreme Court seeking to remove Proposition 50 from the ballot, naming Secretary of State Shirley Weber as a respondent.
• The 400-plus-page filing alleges a single-subject violation, insufficient public notice, and that lawmakers exceeded their authority by advancing maps before any voter-approved constitutional change.
• The court rejected a similar GOP petition last week without a hearing, and election-law scholars said the latest challenge is unlikely to succeed based on California precedent.
• President Donald Trump said the Justice Department plans to sue California over the proposal, and Gov. Gavin Newsom’s campaign responded that opponents will lose in court.
• California’s move is a direct response to Texas Republicans advancing maps projected to add five GOP seats, as a Utah judge separately ordered new congressional lines for 2026, underscoring a broader national fight over redistricting.
