The US Justice Department has entered the fray in a lawsuit initiated by California Republicans, aiming to prevent the California's newly approved electoral boundaries.
This court case, submitted to federal court, challenges the map championed by the state's Democratic governor, which was created in response to a Republican-led gerrymander in Texas.
"California's redistricting scheme represents a brazen power grab that tramples on voting rights and mocks the electoral system," stated the nation's top law enforcement official.
Democrats have expressed confidence that the redistricting plan will survive court challenges.
"These opponents were defeated in the election and they are likely to also lose in court," commented a representative for the governor.
The legal challenge asserts that California's map wrongfully utilized race as a factor to heavily favor Hispanic voters in contravention of the US Constitution.
"Race cannot be used as a proxy to further partisan goals, but that is precisely what the California General Assembly did with Proposition 50," stated a senior official from the DOJ's civil rights unit.
This courtroom confrontation represents the most significant counterpunch by Democrats in the continuing political battle that began in Texas and has spread across multiple states.
Unlike other states, where GOP-controlled legislatures have implemented partisan maps, California's plan required voter approval, which it obtained with nearly 65% of the vote.
Democrats need to flip just a small number of Republican-held House seats to gain majority of the House of Representatives in next year's midterm election.
The party that holds the majority will influence the remaining period of the current administration, deciding if a GOP-controlled legislature will continue to deliver its agenda or face resistance, congressional probes and possible additional obstacles.
