New Jersey Statutes Title 43. Pensions and Retirement and Unemployment Compensation 43 § 15A-140

a. A member making contributions pursuant to the provisions of this supplementary act and who is not eligible for any benefits hereunder, may, upon termination of such service as a member of the Legislature, elect to receive the return of his accumulated contributions in accordance with the provisions of P.L.1954, c. 84, § 41a (C. 43:15A-41a); but if a member of the Legislature is a member of the retirement system on the basis of other public service, no application for a return of contributions may be approved until he has terminated all service covered by the system and makes application for a return of all contributions made to the retirement system. If all or any part of a member's legislative service is applied toward qualifying for benefits under any other provisions of the act to which this act is a supplement, no return of contributions made on the basis of legislative salaries shall be approved; in that event service established as a member of the Legislature and salaries pertaining thereto shall be credited in the same manner as all other service and salaries covered by the retirement system.

b. At the time of retirement, a member enrolled on the basis of legislative as well as other public service shall be permitted to elect the largest possible retirement allowance, if he qualifies for benefits under both the provisions of this supplementary act and the act to which this is a supplement. Upon the election of the legislative retirement benefits provided by this supplementary act, an application for a return of contributions made on the basis of such other public service may be approved.

c. A member of the Legislature electing to receive a retirement allowance under this supplementary act or the act to which this is a supplement shall be ineligible to receive a retirement allowance or pension for the same service under any other law of the State.
