Question: Kentucky's state pension system requires that police officers who are disabled after reaching the age of fifty-five to retire and receive normal retirement benefits, while officers who become disabled prior to age fifty-five receive disability benefits until they reach the normal retirement age of sixty, and then begin receiving pension benefits. Officer Wiggums and his partner are injured after crashing their patrol car during a high speed chase. Wiggums, aged fiftysix, is required to retire and take his pension, while his partner, aged fifty-three, will receive disability benefits until he reaches the age of sixty, and then will begin receiving his pension. Does Kentucky's pension system violate the ADEA? Explain.
