In Buffalo Forge Co. v. Steelworkers of America, the U.S. Supreme Court held in a 5-4 decision that §4 of the Norris-La Guardia Act' prevents a federal court from enjoining a sympathy strike while an arbitrator is deciding whether the strike is covered by a no-strike clause. The Court's decision settled the sole question left unanswered by Boys Markets, Inc. v. Retail Clerks Union.
