A three-judge federal panel in Los Angeles upheld California’s new congressional maps under Proposition 50, rejecting Republican claims they were unconstitutional.

* The maps were designed to flip five Republican-held seats after Texas Republicans redrew their own map.

* Judges Josephine Staton and Wesley Hsu ruled the maps were a partisan gerrymander, not racial.

* Gov. Gavin Newsom praised the ruling, while California Republicans said they will appeal.
