Epic Systems Corp. v. Lewis, 584 U.S. ___ (2018), was a case decided by the Supreme Court of the United States on how two federal laws, the National Labor Relations Act (NLRA) and the Federal Arbitration Act (FAA), relate to whether employment contracts can legally bar employees from collective arbitration. The Supreme Court had consolidated three cases, Epic Systems Corp. v Lewis (Docket 16-285), Ernst & Young LLP v. Morris (16-300), and National Labor Relations Board v. Murphy Oil USA, Inc. (16-307). In a 5–4 decision issued in May 2018, the Court ruled that arbitration agreements requiring individual arbitration and prohibiting class action lawsuits are enforceable under the FAA, regardless of allowances set out within the NLRA.
