The U.S. Supreme Court is reviewing a contentious electoral map from Louisiana, which increased Black-majority districts but faced challenges over potential racial bias in its design. Arguments are centered around the conflict between minority voting rights and the Constitution's equal protection clause.

The U.S. Supreme Court is set on Monday to hear a bid by Louisiana officials and civil rights groups to preserve an electoral map that raised the number of Black-majority congressional districts in the state and prompted a challenge by non-Black voters.

States must balance complying with a civil rights law that protects the voting power of a racial minority while not discriminating against other voters.
