N.J. Stat. § 52:27BBB-19
Notwithstanding the provisions of any other law, rule or regulation to the contrary, an employee of a qualified municipality who is a member of the Public Employees' Retirement System and is otherwise eligible for retirement may, upon the recommendation of the chief operating officer during the rehabilitation term or the mayor during the economic recovery term, with the approval of the director, receive an incentive payment for the termination of the employee's employment with the municipality.
As used in this section, "incentive payment" shall mean a lump sum payment of 20 percent of the employee's annual base salary, exclusive of overtime.
An employee shall only be eligible for an incentive payment pursuant to this section if that person applies for this termination benefit within 60 days of the appointment of the chief operating officer during the rehabilitation term, or within the first 60 days of the economic recovery term. Payment shall be made not sooner than upon the receipt of the first pension check by the municipal employee.
This election to retire on the part of the municipal employee shall be communicated by the member to the retirement system pursuant to Title 43 of the Revised Statutes; however, once the employee has elected to retire, that decision shall be final.
