N.C. Gen. Stat. § 7A-3
Except for the judicial power vested in the court for the trial of impeachments, and except for such judicial power as may from time to time be vested by the General Assembly in administrative agencies, the judicial power of the State is vested exclusively in the General Court of Justice. Provided, that all existing courts of the State inferior to the superior courts, including justice of the peace courts and mayor's courts, shall continue to exist and to exercise the judicial powers vested in them by law until specifically abolished by law, or until the establishment within the county of their situs of a district court, or until January 1, 1971, whichever event shall first occur. Judgments of inferior courts which cease to exist under the provisions of this section continue in force and effect as though the issuing court continued to exist, and the General Court of Justice is hereby vested with jurisdiction to enforce such judgments.
