Bernhardt v. Polygraphic Co. of America, Inc.
United States Supreme Court
350 U.S. 198 (1956)
Bernhardt (plaintiff) worked under a contract with Polygraphic Co. of America (defendant) that required contract disputes to go to binding arbitration under New York law. When a dispute arose, Bernhardt sued instead in federal court in Vermont (a diversity case, since he was a Vermont resident and the company was a New York corporation). The company asked the court to pause the lawsuit and send the case to arbitration. Under Vermont law, arbitration clauses like this one were unenforceable; the district court applied Vermont law and refused to stay the case. The court of appeals reversed, treating the question as "procedural" and therefore governed by federal law favoring arbitration.
Whether a federal court sitting in diversity must decide an issue that substantially affects state-created rights according to state law, rather than federal law, under the Erie doctrine.
