 163-11. Filling vacancies in the General Assembly.(a) If a vacancy shall occur in the General Assembly by death, resignation, or otherwise than by expiration of term, the Governor shall immediately appoint for the unexpired part of the term the person recommended by the political party executive committee provided by this section. The Governor shall make the appointment within seven days of receiving the recommendation of the appropriate committee. If the Governor fails to make the appointment within the required period, he shall be presumed to have made the appointment and the legislative body to which the appointee was recommended is directed to seat the appointee as a member in good standing for the duration of the unexpired term.(b) If the district consists solely of one county and includes all of that county, the Governor shall appoint the person recommended by the county executive committee of the political party with which the vacating member was affiliated when elected, it being the party executive committee of the county which the vacating member was resident.(c) If the district consists solely of one county but includes less than all of the county, the Governor shall appoint the person recommended by the county executive committee of the political party with which the vacating member was affiliated when elected, it being the county executive committee of the county which the vacating member was resident, provided that in voting only those county executive committee members who reside in the district shall be eligible to vote.(d) If the district consists of more than one county, the Governor shall appoint for the unexpired portion of the term the person recommended by the State House of Representatives district committee or the Senatorial district committee of the political party with which the vacating member was affiliated when elected. In the case where all of a county is included within a district, the county convention or county executive committee of that political party shall elect or appoint at least one member from that county to serve on the State House of Representatives district executive committee or State Senatorial district executive committee. In the case where only part of a county is included within a district, the county convention or county executive committee of that political party shall elect or appoint at least one member from that county to serve on the State House of Representatives district committee or the State Senatorial district committee, but only the delegates to the county convention or the members of the county executive committee who reside in the district may vote in electing the district committee member. When the State House of Representatives district committee or the State Senatorial district committee meets, a member shall be entitled to cast for his county (or the part of his county within the district) one vote for each 300 persons or major fraction thereof residing within that county, or in the case where less than the whole county is in the district one vote for each 300 persons or major fraction thereof residing in that part of the district within the county.A county convention or county executive committee may elect more than one member to the district committee but in the event that more than one member is selected from that county, then each member shall cast an equal share of the votes allotted to the county.(e) No person is eligible for appointment to fill a vacancy in the Senate or the House of Representatives under this section, unless that person would have been qualified to vote as an elector for that office if an election were to be held on the date of appointment. This section is intended to implement the provisions of Section 8 of Article VI of the Constitution.
