Sec. 7.05. REEMPLOYMENT OF RETIRED MEMBERS ELIGIBLE TO RECEIVE CERTAIN PENSIONS. If a retired member eligible to receive a normal, early, special early, or deferred vested pension is reemployed by the municipality, the payment of any pension, whether or not payment has begun, to which the retired member is entitled from the plan may not be suspended, whether or not the person again becomes a member. The retired member shall be treated as a new employee for purposes of determining the person's membership in this plan and for purposes of determining the person's service after reemployment. However, for purposes of computing any death benefit under this plan, the previous period of service shall be used if it produces a greater amount of death benefit than the member's last period of service.
