N.C. Gen. Stat. § 97-84
The Commission or any of its members or deputies shall hear the parties at issue and their representatives and witnesses, and shall determine the dispute in a summary manner. The case shall be decided and findings of fact issued based upon the preponderance of the evidence in view of the entire record. The award, together with a statement of the findings of fact, rulings of law, and other matters pertinent to the questions at issue shall be filed with the record of the proceedings, within 180 days of the close of the hearing record unless time is extended for good cause by the Commission, and a copy of the award shall immediately be sent to the parties in dispute. If the deputy or member of the Commission that heard the parties at issue and their representatives and witnesses is unable to determine the matters in dispute and issue an award, the Commission may assign another deputy or member to decide the case and issue an award.
