JUSTICE O'CONNOR, concurring in the judgment.
Based on the legislative history of the Norris-La Guardia Act, 29 U.S.C. § 101 et seq., and our previous cases interpreting it, e.g., New Negro Alliance v. Sanitary Grocery Co., 303 U. S. 552 (1938), the Court correctly concludes that this case involves a labor dispute within the meaning of § 4 of the Act, 29 U.S.C. § 104. The Court also correctly determines that, under Buffalo Forge Co. v. Steelworkers, 428 U. S. 397 (1976), no injunction may issue pending arbitration because the underlying political dispute is not arbitrable under the collective bargaining agreement. Unless the Court is willing to overrule Buffalo Forge, the conclusion reached by the Court in this case is inescapable. Therefore, I concur in the judgment.
