As was the case in other states where rural legislators hung on to power despite changes in state demographics, North Carolina eventually had to redefine its method of electing house members and to reapportion congressional seats, which was supposed to be done after every decennial census. At a time of civil rights legislation to end segregation (Civil Rights Act of 1964) and enforce the constitutional right to vote for African Americans and other minorities (Voting Rights Act of 1965), the US Supreme Court made rulings that resulted in corrections to state legislature representation and apportionment in several states.
