Radanovich says the recently drawn maps are illegal and unconstitutional. The lawsuit targets three Los Angeles districts claiming the district lines were redrawn to protect incumbents.
Meanwhile, the Redistricting Commission has said that the new maps would withstand any legal challenge.
Radanovich told Action News, "I think everyone deserves a fair and unbiased commission, but we didn't get one. As a republican, I hope the master appointed by the state supreme court, if this lawsuit is successful, will do a fair and unbiased job."
