Moses H. Cone Memorial Hospital v. Mercury Construction Corp., 460 U.S. 1 (1983), commonly cited as Moses Cone or Cone Hospital, is a United States Supreme Court decision concerning civil procedure, specifically the abstention doctrine, as it applies to enforcing an arbitration clause in a diversity case. By a 6–3 margin, the justices resolved a complicated construction dispute by ruling that a North Carolina hospital had to arbitrate a claim against the Alabama-based company it had hired to build a new wing, even though it meant that it could not consolidate it with ongoing litigation it had brought in state court against the contractor and architect.
