N.J. Stat. § 19:6-4
A judge of the Superior Court or the county board shall have power to dismiss any member of a district board from such board for an illegal act, or for any cause which shall be determined in a summary way by such judge or county board. The county board shall dismiss the members of a district board from such board if upon any recount of the votes cast in such district it shall appear that errors occurred in the count or the certificate thereof, which, under the provisions of this Title, are sufficient to cause the costs of such recount to be paid by the State, county or municipality; and no person so removed from any board shall thereafter be eligible to serve as a member of the same or any other district election board. Application for the removal of all of the members, or of any member of any district election board, may, within ten days after the final order has been entered on any recount which may have been allowed affecting such district, be made by any candidate at the last election to a judge of the Superior Court or the county board. On the application, summary hearings shall be held to determine whether the board or the member was incompetent or careless in the receipt of illegal votes or the rejection of legal votes or otherwise in the conduct of the election generally. If, upon such hearing, it appears to the judge or the county board, as the case may be, that such incompetency or carelessness existed, the board or the member thereof found so to be incompetent or careless shall be removed and upon such removal disqualified from further service as a member of any district board.
