New Jersey Statutes Title 43. Pensions and Retirement and Unemployment Compensation 43 § 13-10

If any municipal employee shall be suspended, dropped or discharged from his employment after having paid his assessments for a period over one year and his suspension or discharge shall continue for a period longer than two years, the moneys he shall have paid into the pension fund due to the assessments shall be returned to him; but such person shall not thereafter be eligible for a pension under this article unless upon a re-employment by the city he shall repay to the fund the amount of any rebate made to him. The obligation to refund payments made to the pension fund shall not apply to an employee suspended or discharged for causes which bar him from eligibility to reappointment under the civil service rules. No other refund of assessments collected from the salaries of such employees shall be made.
