In a 5-4 decision, the United States Supreme Court settled a split among the federal appellate circuits on whether appeal of a district court refusal to compel arbitration stays the underlying litigation in the district court.

Having been denied relief by the district court on its motion to compel arbitration, plaintiff filed an interlocutory appeal to the Ninth Circuit under the Federal Arbitration Act, 9 U. S. C. §16(a), which authorizes an interlocutory appeal from the denial of a motion to compel arbitration. Plaintiff asked the district court to stay its proceedings pending resolution of the interlocutory appeal. The district court refused, and the Ninth Circuit also declined to stay the lower court proceedings pending appeal.
