California Republican lawmakers asked the state’s Supreme Court on Monday to block a November 4 special election that would let voters decide whether to replace the congressional map drawn by the independent redistricting commission with one approved last week by the Democratic-controlled Legislature. The emergency petition in Sanchez v. Weber argues that Governor Gavin Newsom’s plan violates the state constitution by bypassing the commission, ignoring a 30-day public-notice requirement and conducting mid-decade redistricting. Newsom has framed the new map as a necessary response to a recently enacted, GOP-favored redraw in Texas, saying California cannot "unilaterally disarm" in the national fight over House control. Independent analysts estimate the proposal could flip as many as five Republican-held districts to Democrats in the 2026 midterms. Monday’s lawsuit comes four days after the California Supreme Court declined to halt the legislation itself, a ruling that cleared the way for the ballot measure. Public opinion is mixed: a UC Berkeley Institute of Governmental Studies survey conducted August 17 found 48% of registered voters support the temporary partisan redraw and 32% oppose it, with support rising to 55% among likely voters. The court has not indicated when it will rule on the new challenge.
