N.J. Stat. § 52:27BBB-11
Within 30 days of the assumption of job responsibilities on the part of the chief operating officer, the chief operating officer shall, in consultation with the mayor, recommend the interim appointment of department heads and submit the list of nominees to the governing body for confirmation. The department heads shall include a business administrator, or functional equivalent thereof, who shall not be the chief operating officer. The governing body may only reject a candidate by a 2/3 vote of the fully authorized membership of the governing body. In the event of an impasse in the appointment process, the matter shall be decided by the special arbitrator, whose decision shall not be subject to appeal. In making a determination pursuant to this subsection, the special arbitrator shall uphold the appointment recommended by the chief operating officer if, by any objective measure, the person under consideration for that position is qualified by reason of experience, education or training.
These interim appointees shall fulfill those responsibilities delegated to them by the chief operating officer pending the completion of the municipal management study by the chief operating officer pursuant to section 12 of P.L. 2002, c. 43(C.52:27BBB-12).
