N.J. Stat. § 38A:13-1.2
Any person who becomes a member of the organized militia of the State of New Jersey shall be deemed to have surrendered his right to any other method, form or amount of compensation or determination thereof from the State or the organized militia, other than as provided in this chapter for any injury or death occurring to him in line of duty. Such entry into the militia shall bind the member's personal representative, surviving spouse and next of kin, as well as the State of New Jersey and the organized militia.
Neither the State, the organized militia nor any member of the organized militia shall be liable to anyone at common law or otherwise for an injury or death compensable under this chapter, including any injury or death that results from an act or omission occurring while the member was in the same service of the organized militia as the person whose actions caused that injury or death, except for injury or death caused by an intentionally wrongful act of a comember.
