N.C. Gen. Stat. § 163-34
Each county board of elections shall possess full power to maintain order, and to enforce obedience to its lawful commands during its sessions, and shall be constituted an inferior court for that purpose. If any person shall refuse to obey the lawful commands of any county board of elections, or by disorderly conduct in its hearing or presence shall interrupt or disturb its proceedings, it may, by an order in writing, signed by its chairman, and attested by its secretary, commit the person so offending to the common jail of the county for a period not exceeding 30 days. Such order shall be executed by any sheriff to whom the same shall be delivered, or if a sheriff shall not be present, or shall refuse to act, by any other person who shall be deputed by the county board of elections in writing, and the keeper of the jail shall receive the person so committed and safely keep him for such time as shall be mentioned in the commitment: Provided, that any person committed under the provisions of this section shall have the right to post a two hundred dollar ($200.00) bond with the clerk of the superior court and appeal to the superior court for a trial on the merits of his commitment.
