N.C. Const. art. VI, § 9

(1) Prohibitions. It is salutary that the responsibilities of self-government be widely shared among the citizens of the State and that the potential abuse of authority inherent in the holding of multiple offices by an individual be avoided. Therefore, no person who holds any office or place of trust or profit under the United States or any department thereof, or under any other state or government, shall be eligible to hold any office in this State that is filled by election by the people. No person shall hold concurrently any two offices in this State that are filled by election of the people. No person shall hold concurrently any two or more appointive offices or places of trust or profit, or any combination of elective and appointive offices or places of trust or profit, except as the General Assembly shall provide by general law.

(2) Exceptions. The provisions of this Section shall not prohibit any officer of the military forces of the State or of the United States not on active duty for an extensive period of time, any notary public, or any delegate to a Convention of the People from holding concurrently another office or place of trust or profit under this State or the United States or any department thereof.
