Notwithstanding the provisions of any other law, code or charter, the county of Nassau shall provide for the defense of any civil action or proceeding brought against a duly appointed police officer of the Nassau county police department and shall indemnify and save harmless such police officer from any judgment of a court of competent jurisdiction whenever such action, proceeding or judgment is for damages, including punitive or exemplary damages, arising out of a negligent act or other tort of such police officer committed while in the proper discharge of his duties and within the scope of his employment. Such proper discharge and scope shall be determined by a majority vote of a panel consisting of one member appointed by the Nassau county board of supervisors, one member appointed by the Nassau county executive, and the third member being the Nassau county police commissioner or a deputy police commissioner.
