Rightwing justices ordered Louisiana in 6-3 vote to redraw congressional maps in blow to the Voting Rights Act

The US supreme court issued a landmark ruling on Wednesday, Louisiana v Callais, relating to how states draft congressional maps under the key civil rights statute, the Voting Rights Act.

By a margin of 6-3, the rightwing justices who control America's top court ordered Louisiana to redraw congressional maps that gave African Americans the chance to elect their candidates of choice proportionate to their population size. The majority dismissed this as an unconstitutional racial gerrymander".
