Handing a victory to a class of older workers, the Ninth Circuit U.S. Court of Appeals held Wednesday that the state can’t use age as a factor when calculating disability retirement benefits.

In Arnett v. California Public Employment Retirement System, 99 C.D.O.S.4184, the court sided with a group of retired state police and correctional officers who claimed that using a worker’s starting age to determine disability benefits violates the Age Discrimination in Employment Act.
