US Appeals Court Upholds California's Prop 50 Redistricting Plan
Court Backs California's Prop 50 Maps in Gerrymandering Row

A federal appeals court has delivered a significant victory to Democrats in California, upholding a controversial ballot measure that redraws congressional district boundaries to offset Republican redistricting efforts in Texas.

Court Rejects Republican Legal Challenge

On Wednesday, a three-judge panel ruled 2–1 to deny a Republican-led request to block the implementation of Proposition 50. The measure, approved by California voters, creates temporary congressional maps aimed at helping Democrats flip up to five Republican-held US House seats. The judges found that the plaintiffs, who argued the maps violated the Voting Rights Act by favouring Hispanic and Latino voters, failed to prove discriminatory intent.

Republican opponents had taken the case to court, claiming the process intentionally crafted districts to advantage specific racial demographics. However, the majority opinion stated clearly: “The United States fails to show that the voters acted with discriminatory intent.”

A Political Tit-for-Tat Across States

The genesis of Prop 50 lies in a partisan battle stretching from Sacramento to Austin. As the 2026 midterm elections approach, former President Donald Trump urged officials in Texas to redraw congressional maps to boost Republican representation. In response, California's Democratic Governor, Gavin Newsom, spearheaded a special statewide vote to enact counter-measures.

“Republicans’ weak attempt to silence voters failed,” Newsom declared in a statement following the ruling. “California voters overwhelmingly supported Prop 50 – to respond to Trump’s rigging in Texas – and that is exactly what this court concluded.”

The approved initiative directly targets districts including one formerly represented by the late Republican congressman Doug LaMalfa.

The Legal Hurdle of Proving Racial Gerrymandering

The legal landscape for challenging such maps is complex. A prior Supreme Court ruling declared that claims of partisan gerrymandering are not subject to judicial review. This means challengers must prove that race, not politics, was the predominant factor in redrawing the lines—the same high bar Democrats faced when contesting Texas's maps.

In their lawsuit, Republicans pointed to comments from Democratic legislators and consultants suggesting the plan preserved districts originally drawn by an independent commission to enhance representation for voters of colour. They argued proper procedures were not followed.

Democrats robustly defended the maps, citing independent analysis showing no increase in Latino-majority districts. They insisted the goal was purely political: to neutralise Republican gains in Texas, not to racially gerrymander.

The judicial split fell along partisan lines. Judges Josephine Staton (an Obama appointee) and Wesley Hsu (a Biden appointee) formed the majority. Dissenting, Trump-appointed Judge Kenneth K. Lee argued Democrats had crafted at least one southern California district specifically “to prevent Latino voters from drifting away from the party”.

With this ruling, the Prop 50 maps are set to govern the 2026, 2028, and 2030 congressional elections. The dispute is widely expected to be appealed to the US Supreme Court, which previously allowed Texas's revised district lines to remain in place. The decision underscores the intensely political and legally fraught nature of redistricting in contemporary America.
