California GOP Asks Supreme Court to Block Prop. 50 Mid‑Decade House Map After Panel Upheld Plan Targeting Five GOP Seats
A three‑judge federal panel upheld Proposition 50 and allowed California to use its newly redrawn congressional map—noting the plan was a partisan gerrymander intended to flip five Republican‑held seats but finding plaintiffs had not proven race was the predominant factor—while the court denied an injunction so the map will be used as litigation continues; voters had approved Prop. 50 by about 64% and a dissenting judge and DOJ lawyers argued the plan reflected racial motivations. The California GOP has filed an emergency application with the U.S. Supreme Court seeking to block the map and reinstate the 2021 Citizens Redistricting Commission lines, arguing unlawful racial use and irreparable harm, setting up an expected appeal amid a broader wave of mid‑decade redistricting fights nationwide.
📌 Key Facts
- A three‑judge federal panel (Central District of California) issued a 2–1 ruling upholding Proposition 50 and allowing California’s newly redrawn congressional map to be used for the 2026–2030 cycles; the court denied the GOP plaintiffs’ request for an injunction so the map will be used while appeals continue.
- The majority opinion (Judge Josephine Staton) explicitly described Prop 50 as a partisan gerrymander “designed to flip five Republican‑held seats to the Democrats,” but found the plaintiffs failed to prove race was the predominant factor, making the map lawful under current precedent.
- Judge Kenneth Lee (dissent) and California Republicans argued parts of the plan used race to boost Latino voting power and cited public statements by consultant Paul Mitchell; Mitchell had been referenced heavily by plaintiffs but did not testify.
- The U.S. Department of Justice’s Civil Rights Division also sued and argued race was used as a proxy to justify Democratic‑leaning districts, but the panel rejected those claims; PBS and other outlets note DOJ has so far only sued in California among the mid‑decade remapping actions.
- Proposition 50 was approved by voters in a special Nov. 4 election by roughly 64%, a fact the majority said weighed against finding a racial gerrymander and that factored into the court’s reasoning.
- California Republicans have filed an emergency application with the U.S. Supreme Court asking it to enjoin use of the Prop 50 map and require a return to the 2021 Citizens Redistricting Commission map, arguing the new plan is an unconstitutional, race‑based power grab that will cause irreparable harm.
- Gov. Gavin Newsom framed Prop 50 as a response to partisan mid‑decade remapping elsewhere, saying it was meant “to respond to Trump’s rigging in Texas” and calling the GOP challenge a “weak attempt to silence voters.”
- The California litigation is part of a broader mid‑decade redistricting wave spurred by former President Trump’s push: about one‑third of states have considered reshaping House districts, six states have already adopted mid‑decade maps, and across those changes Republicans currently see roughly nine favorable seats to Democrats’ six (a tentative GOP net gain of three), with several legal battles and a recent Supreme Court order allowing Texas’s contested map to stand cited as relevant precedent.
