The amount of any overpayment, of any pension or benefit granted under this Article, due to fraud, misrepresentation or error, may be deducted from future payments or refunds made to the recipient of the overpayment. The board also may withhold payment of any benefits or pensions payable under this Article where any type of lawsuit or Workers’ Compensation suit has been instituted until the specific liability of the board and the fund for payments due is established by the adjudication or dismissal of the suit. Any such action of the board shall relieve and release the board and the fund from any liability for any moneys deducted or withheld.
