N.C. Const. art. IV, § 11

Assignment of Judges. The Chief Justice of the Supreme Court, acting in accordance with rules of the Supreme Court, shall make assignments of Judges of the Superior Court and may transfer District Judges from one district to another for temporary or specialized duty. The principle of rotating Superior Court Judges among the various districts of a division is a salutary one and shall be observed. For this purpose the General Assembly may divide the State into a number of judicial divisions. Subject to the general supervision of the Chief Justice of the Supreme Court, assignment of District Judges within each local court district shall be made by the Chief District Judge.
