Redistricting and the Courts in Wisconsin

From Mark Pitsch’s article in the Wisconsin State Journal:

The Legislature ‘s top Republican says the Wisconsin Supreme Court is exceeding its authority by drafting plans to rewrite the boundaries of voting districts.
***
The Supreme Court says it has to be ready to write legislative district maps in the event lawmakers can ‘t agree or the Legislature ‘s plan is challenged in court.
***
The redistricting committee has proposed that if lawmakers can ‘t agree on a redistricting plan, a panel of five appeals court judges would be appointed to map out new districts.The state Supreme Court would then review the map if there were to be a court challenge.That process would make state judges, rather than the federal courts, responsible for handling redistricting in the event of a legislative failure.
