Rucho v. Common Cause

In Rucho v. Common Cause, the U.S. Supreme Court addressed the justiciability of partisan gerrymandering claims. Following the 2010 census, North Carolina's Republican-led legislature drew a congressional map heavily favoring Republicans. Common Cause and other plaintiffs sued, alleging violations of the Equal Protection Clause, First Amendment, and Elections Clause. A federal district court struck down the map as an unconstitutional partisan gerrymander. On appeal, consolidated with Lamone v. Benisek (a Democratic gerrymandering case from Maryland), the Supreme Court ruled 5-4. Chief Justice John Roberts wrote for the majority that partisan gerrymandering claims present a political question beyond the reach of federal courts. The Court found no judicially discoverable and manageable standards to decide such cases, vacated the lower court rulings, and ordered dismissal for lack of jurisdiction, thereby foreclosing federal judicial review of partisan district maps.

The Supreme Court, by a 5-4 vote, held that partisan gerrymandering claims are nonjusticiable political questions. The Court vacated the district court decisions and directed that the cases be dismissed for lack of federal jurisdiction.

Whether claims of unconstitutional partisan gerrymandering are justiciable in federal court, or whether they present a nonjusticiable political question under the U.S. Constitution.

The ruling closed federal courts to partisan gerrymandering challenges, shifting the battle to state courts, legislatures, and ballot initiatives. It intensified national debate over electoral fairness and led to renewed calls for independent redistricting commissions. Critics argued the decision insulates extreme partisan maps from judicial scrutiny and undermines democratic representation, while supporters praised it as a necessary restraint on judicial overreach into inherently political processes. The decision remains a landmark setback for federal voting rights litigation.
