The Supreme Court on Wednesday blocked a revised plan for legislative districts in Wisconsin that created a new Black voting district and was opposed by Republicans.

The new map, drawn by Democratic Gov. Tony Evers, created one new Black-majority state House district touching Milwaukee. Republicans urged the court to block the plan and instead revert to boundaries drawn up by the GOP-controlled Legislature. Those were rejected by the state Supreme Court, which ordered election officials to follow the governor’s map instead.

In an unsigned opinion, the Supreme Court said the governor’s plan embraced “the sort of uncritical majority-minority district maximization that we have expressly rejected.”
