Moore v. Harper

Summary

The Court held that it had jurisdiction to review the state supreme court’s prior judgment because the judgment continued to bar use of the 2021 congressional maps and reversal could provide the legislative defendants complete relief. On the merits, the Elections Clause does not give state legislatures exclusive authority insulated from state constitutional constraints; state legislatures remain subject to ordinary state judicial review. The Court declined to decide whether the state court exceeded the limits of that review because the issue was not adequately preserved.
