(c) Any State board, committee, council, or commission created by any official in the executive branch of State government, other than by those officials specified in subsections (a) and (b) of this section, expires two years after it was created; provided, however, that any board, committee, council, or commission existing as of July 1, 1984, expires on June 30, 1985, unless it was due to expire on an earlier date. The Governor may extend any such board, committee, council, or commission before it expires for additional periods of up to two years by executive order; copies of the executive order shall be filed by the Governor with the Secretary of State and the Legislative Library. The words, "official in the executive branch of State government," as used in this section, do not include officials of counties, cities, towns, villages, other municipal corporations or political subdivisions of the State or any agencies of such subdivision, or local boards of education, other local public districts, units or bodies of any kind, or community colleges as defined in G.S. 115D-2(2), or private corporations created by act of the General Assembly.
