S.C. Code § 17-5-220
A county with a population of 100,000 or more, according to the last official United States census, may establish by appropriate implementing resolution a commission to be known as the medical examiner commission of that county, composed of five members, one of whom must be the chief administrative officer of the county health department who is a permanent member, and four of whom must be appointed by the Governor upon recommendation of the county legislative delegation. The initial terms of the appointive members are as follows: one member for a term of one year, one member for a term of two years, one member for a term of three years, and one member for a term of four years. After the initial terms, all members serve for terms of four years. The effective date of appointments is July first with terms expiring on June thirtieth. The members must serve without compensation. The length of the terms of those who serve first must be determined by lot at the first meeting of the commission.
The commission must meet as soon as practicable after appointment and must organize itself by electing one of its members as chairman and other officers as may be considered necessary. After this first meeting, the commission must meet at least every six months and more often as its duties require, upon the call of the chairman or a majority of its members.
The commission is authorized to adopt and promulgate regulations as it may consider necessary.
