Fox Film Corp. v. Muller

Fox Film (plaintiff) sued Muller (defendant) in state court for breach of movie-licensing contracts. Muller argued the contracts violated the Sherman Antitrust Act and, separately, that an invalid arbitration clause voided the entire agreement, relying on a prior federal case that had already found a similar arbitration clause invalid. The state trial court dismissed on both grounds, and the Minnesota Supreme Court affirmed relying solely on the arbitration-clause ground, finding it tainted the whole contract. The U.S. Supreme Court granted certiorari.
