N.J. Stat. § 43:1-3.3
A State, county or local employer participating in a State or locally-administered pension fund or retirement system shall be responsible for reimbursement to the pension fund or retirement system of all pension costs incurred by a State or locally-administered pension fund or retirement system following any settlement agreement between the employer and an employee that provides for the employer not to pursue any civil or criminal charges or an action for misconduct against the employee in exchange for the employee's resignation in good standing when the employer has failed to fully disclose the settlement to the board of trustees of the pension fund or retirement system so that it can determine whether to order the forfeiture of all or part of the earned service credit or pension or retirement benefit of any member of the fund or system for misconduct occurring during the member's public service which renders the member's service or part thereof dishonorable.
