New Jersey Statutes Title 2A. Administration of Civil and Criminal Justice 2A § 23B-14

a. An arbitrator or an arbitration organization acting in that capacity is immune from civil liability to the same extent as a judge of a court of this State acting in a judicial capacity.

b. The immunity afforded by this section supplements any immunity pursuant to other law.

c. The failure of an arbitrator to make a disclosure required by section 12 of this act  1 does not cause any loss of immunity pursuant to this section.

This subsection does not apply:

e.
