N.C. Gen. Stat. § 1-567.81

(1) Evidence of anything said or of an admission made in the course of a conciliation is not admissible, and disclosure of that evidence shall not be compelled in any arbitration or civil action in which, under law, testimony may be compelled to be given. This subsection does not limit the admissibility of evidence when all parties participating in conciliation consent to its disclosure.

(2) If evidence is offered in violation of this section, the arbitral tribunal or the court shall make any order it considers appropriate to deal with the matter, including an order restricting the introduction of evidence or dismissing the case.

(3) Unless the document otherwise provides, a document prepared for the purpose of, in the course of, or pursuant to the conciliation, or a copy of such document, is not admissible in evidence, and disclosure of the document shall not be compelled in any arbitration or civil action in which, under law, testimony may be compelled.
