Supreme Court Rejects "Independent State Legislature" Theory in Moore v. Harper -- Preserves State Court Oversight of Redistricting

In a 6-3 decision, Chief Justice Roberts wrote that the Constitution's Elections Clause "does not insulate state legislatures from the ordinary exercise of state judicial review." The case arose from North Carolina Republican legislators' argument that state courts had no authority to review their redistricting decisions -- a theory central to some of Trump's arguments to overturn the 2020 election. Justices Thomas, Alito, and Gorsuch dissented. The ruling had limited practical effect because the NC Supreme Court's new Republican majority had already reversed its own anti-gerrymandering precedent.
