Federal authorities have entered the fray in a legal challenge initiated by California Republicans, aiming to halt the state's recently passed congressional redistricting map.
This legal action, submitted to a US district court, challenges the redistricting plan supported by the state's Democratic governor, which was created in reaction against a Republican-led gerrymander in Texas.
"The state's redistricting scheme represents a brazen power grab that violates voting rights and mocks the electoral system," declared the US attorney general.
The Democratic party have voiced assurance that the redistricting plan will survive court challenges.
"These opponents were defeated in the election and soon they will face defeat in the judicial system," stated a representative for the governor.
The legal challenge asserts that California's map improperly used racial considerations to significantly advantage Latino communities in contravention of the US Constitution.
"It is unconstitutional to use race as a substitute to further partisan goals, but that is precisely what the California General Assembly did with Proposition 50," argued a high-ranking representative from the DOJ's civil rights unit.
The legal battle represents the major counterpunch by the Democratic party in the continuing redistricting war that started with Texas and has extended to multiple states.
In contrast to elsewhere, where GOP-controlled legislatures have implemented partisan maps, California's plan required public consent, which it obtained with nearly 65% of the vote.
Democrats need to gain just a handful of GOP-controlled House seats to take control of the House of Representatives in next year's congressional elections.
The political group controlling the majority will shape the remaining period of the sitting president's term, determining whether a unified Republican Congress will persist in implementing its political program or encounter opposition, investigations and potential further challenges.
