The state’s voters approved the redistricting plan last year as a Democratic counterresponse to Texas’ new GOP-friendly map, which President Trump pushed for to help Republicans hold on to their narrow majority in the House.

And in a brief, unsigned order released Wednesday, the high court denied an emergency request by the California’s Republican Party to block the redistricting plan. The state’s GOP argued that the map violated the U.S. Constitution because its creation was mainly driven by race, not partisan politics. A lower federal court rejected that claim.

The ruling on California’s redistricting plan comes two months after the Supreme Court cleared the way for the Texas map that kicked off a nationwide gerrymandering fight by boosting the GOP’s chances of winning five additional House seats.
