Supreme Court rejects theory that would have meant radical changes to election rules

The Supreme Court on Tuesday rejected what would have been a radical change in election law, dismissing the theory that state legislatures have almost unlimited power to decide the rules for federal elections and draw partisan congressional maps without interference from state courts.

The Constitution’s elections clause “does not insulate state legislatures from the ordinary exercise of state judicial review,” Chief Justice John G. Roberts Jr. wrote in a 6-3 decision.
