Be it enacted by the Senate and House of Representatives in General Court assembled, and by the authority of the same, as follows:
Notwithstanding any general or special law to the contrary, Frederick Nasson shall be eligible to be reinstated as a member in service of the state retirement system as of the effective date of this act, if he repays to the state retirement system an amount equal to the total amount of any retirement allowance received by him together with interest thereon, such repayment to be made in 1 sum or in installments as the state board of retirement shall prescribe. Upon such reinstatement, regular deductions shall be made from his regular compensation pursuant to paragraphs (b) and (b>) of subdivision (1) of section 22 of chapter 32 of the General Laws, for purposes of which his date of entry into service shall be the date he waived his retirement allowance. Upon completion of such repayment, said Frederick Nasson shall be entitled to creditable service for all periods for which deductions were made from his regular compensation.
Upon reinstatement as a member in service of the state retirement system, said Frederick Nasson shall be eligible, upon the payment of regular deductions together with interest thereon to establish creditable service with the said system for the period of service during which he previously waived his retirement allowance. Such payment will be made in 1 sum.
In no event shall Frederick Nasson be allowed to retire until he has made the repayments required by the first paragraph of this act in full. Any pension allowance, or other retirement benefit provided hereunder shall be exclusive of and in the alternative to any other pension, allowance, or other retirement benefit, including any provided for under general or special law.
