Alabama election map diluted black vote, Supreme Court rules

The US Supreme Court has ruled that an Alabama electoral map violated federal law prohibiting racial discrimination in voting.

The 5-4 decision backed a lower court's decision that the state's Republican-drawn map had diluted the voting power of black Alabamians.

The map, outlining the state's seven districts for the US House of Representatives, was approved in 2021.

The ruling preserves a key element of the landmark 1965 Voting Rights Act.
