The US Court of Appeals for the Sixth Circuit recently affirmed a district court’s decision to grant defendant-appellee TRW Vehicle Safety Systems, Inc.’s (TRW) motion to compel arbitration, finding that TRW retirees were bound by an arbitration provision in a collective bargaining agreement (CBA) negotiated prior to their retirement. The lower court had held that plaintiffs Norman VanPamel and Thomas Slaght, former employees of TRW suing on behalf of a putative class, were required to arbitrate contract and Employee Retirement Income Security Act (ERISA) claims challenging changes TRW made to prescription drug benefits in their retiree health plans.
