N.J. Stat. § 10:4-17
Any person who knowingly violates any of the foregoing sections of this act shall be fined $100.00 for the first offense and no less than $100.00 nor more than $500.00 for any subsequent offense, recoverable by the State by a summary proceeding under "the penalty enforcement law" (N.J.S. 2A:58-1 et seq.). The Superior Court shall have jurisdiction to enforce said penalty upon complaint of the Attorney General or the county prosecutor. Whenever a member of a public body believes that a meeting of such body is being held in violation of the provisions of this act, he shall immediately state this at the meeting together with specific reasons for his belief which shall be recorded in the minutes of that meeting. Whenever such a member's objections to the holding of such meeting are overruled by the majority of those present, such a member may continue to participate at such meeting without penalty provided he has complied with the duties imposed upon him by this section.
