Whenever a vacancy occurs in the membership of the Board of County Commissioners for any reason other than the expiration of the term, it shall be filled for the unexpired term at the next general election occurring not less than 60 days from the date of such vacancy; provided, however, that if the vacancy occurs at any time after 60 days prior to the general election occurring in the next to the last year in the term of office, the vacancy may be filled by appointment for the remainder of the unexpired term in the same manner as hereinafter provided for temporary appointments. Nominations and elections for the filling of a vacancy for the unexpired term shall be made in accordance with the pertinent provisions of Title 19 of the Revised Statutes and the "Optional County Charter Law" (P.L. 1972, c. 154).
The Board of County Commissioners may, by majority vote of its remaining members, fill vacancy temporarily by appointment until the election and qualification of a successor. If the Board of County Commissioners shall fail to fill the vacancy within 30 days of its occurrence, the office shall remain vacant until the election and qualification of a person to fill the vacancy for the unexpired term or to fill a full new term, as the case may be.
