N.C. Gen. Stat. § 1-567.64

Subject to the relevant provisions of federal law and any applicable international agreement in force between the United States of America and any other nation or nations, an arbitral award may be vacated by a court only upon a showing that the award is tainted by illegality, or substantial unfairness in the conduct of the arbitral proceedings. In determining whether an award is tainted, the court shall consider the provisions of this Article, but shall not engage in de novo review of the subject matter of the dispute giving rise to the arbitration proceedings.
