California Republicans promptly initiated a federal lawsuit aiming to prevent the implementation of a new, gerrymandered House map. This map, proposed by the state’s Democratic leadership and approved by voters this week, marks the latest move in the ongoing nationwide disputes over congressional boundaries ahead of the 2026 midterm elections.

The legal challenge was filed just one day after California voters endorsed Proposition 50—a ballot initiative that permits a new map, favoring Democrats in five additional districts, to be enforced until 2030.

This measure was championed by Democratic California Governor Gavin Newsom to counteract Texas Republicans’ own adoption of a gerrymandered map, enacted at the request of President Donald Trump. The GOP is seeking to improve its chances of retaining its narrow House majority in next year’s elections. Trump labeled Proposition 50 a “giant scam” and alleged the vote was “rigged” on Election Day morning, before polling stations closed.   

In Wednesday’s lawsuit, California Republicans alleged that the state legislature violated the 14th and 15th Amendments “by drawing new congressional district lines based on race, specifically to favor Hispanic voters, without cause or evidence to justify it.”

Newsom’s press office stated on Wednesday that officials had not yet reviewed the lawsuit but asserted that “if it’s from the California Republican Party and Harmeet Dhillon’s law firm, it’s going to fail.” (The lawsuit was submitted on behalf of state Republicans by Dhillon Law Group Inc.; Dhillon, the firm’s founder, currently serves as the Assistant Attorney General for Civil Rights at the Department of Justice, a position Trump appointed her to following his reelection.)

The endeavor to block the new map joins an expanding list of legal challenges: congressional maps have been subjected to numerous legal challenges this year.

The following provides essential information regarding the lawsuit.

Claims Allege New Districts Were Drawn to Benefit Latino Voters

The legal complaint, lodged in the U.S. District Court for the Central District of California, contends that California’s new voter-approved map is unconstitutionally discriminatory because it was designed to give an advantage to Latino voters.

“While the Constitution entrusts States with designing congressional districts, the Supreme Court has also held that states may not, without a compelling reason backed by evidence that was in fact considered, separate citizens into different voting districts on the basis of race,” the lawsuit noted.

In it, California Republicans referenced a press release from the state legislature which stated that Proposition 50 would “empower Latino voters to elect their candidates of choice.” They also highlighted remarks made by Democratic officials and a consultant who discussed drawing districts with Latino majorities. 

The plaintiffs conceded that race-based redistricting can be justified in some cases under the Voting Rights Act, which prohibits racial discrimination in voting.

The complaint argued, however, that Latino voters in California have been able to elect candidates they preferred “without being thwarted by a racial majority voting as a bloc” and that the legislature lacked evidence that the state’s previous congressional map violated the Voting Rights Act because it usually prevented them from doing so.

Therefore, California Republicans alleged, the new map is a result of “unconstitutional racial gerrymandering” that violates both the 14th Amendment’s Equal Protection Clause and the 15th Amendment, which prohibits states from denying or abridging citizens’ right to vote because of their race or color. 

The lawsuit asks the court to “invalidate” the map and “require that any future use of race in drawing lines” complies with federal law. 

The Supreme Court is currently deliberating on allegations of racial gerrymandering in a separate case, Louisiana v. Callais, which could have a broader impact on states’ ability to consider race as a factor when drawing House maps. The justices heard arguments concerning the legality of the state’s creation of a second Black-majority district this year, but have not yet issued a decision. 

Democratic Reactions to the Lawsuit 

Democratic House Minority Leader Hakeem Jeffries dismissed the lawsuit as “frivolous,” asserting that California’s new map does not disadvantage minority voters and is distinct from Texas’, which is expected to cause the loss of seats held by Black or Hispanic Congressmen.   

“It’s very different,” Jeffries remarked, “than what the people decided in California, to make sure that they had a fair map.”

Newsom has not issued a public statement on the lawsuit, but responded to criticism from Republican House Speaker Mike Johnson, who called Proposition 50 a “sign of desperation” and a “game to 

rig the election.” 
“Cry harder,” Newsom retorted with “Cry harder” on X.
