S.C. Code Ann. § 23-4-140: Meetings; quorum; proxies.

The committee shall meet as soon as practical after appointment and at this meeting organize and adopt rules for governing its proceedings. The committee shall meet at those other times as may be designated by the chairman or the Governor. A majority of the members at any regular meeting or called meeting constitutes a quorum. Both appointed at-large members and ex officio members of the committee may be represented by proxy, but only ex officio proxies have voting rights and must be included in determining a quorum.
