The congressional map approved by California voters to boost the number of House Democrats was upheld Wednesday by a divided federal court, which said they were legally drawn for political purposes and not as an act of racial discrimination, as Republicans contended.

Proposition 50, pushed by Gov. Gavin Newsom and approved by more than 64% of the voters on Nov. 4, was immediately challenged by the state’s Republican Party and the Trump administration. While the Supreme Court has allowed states to redraw their districts in order to help a favored political party, the Republicans argued that the California maps were designed to benefit Hispanic candidates in Los Angeles and the San Joaquin Valley.

The U.S. District Court panel disagreed in a 2-1 ruling. The majority cited the Supreme Court’s Dec. 4 decision allowing Texas Republicans to redraw their districts in order to gain five House seats this year – rejecting arguments by Democrats that the new lines were racially discriminatory.
