N.C. Gen. Stat. § 1-500
Whenever a plaintiff shall appeal from a judgment rendered at chambers, or in session, either vacating a restraining order theretofore granted, or denying a perpetual injunction in any case where such injunction is the principal relief sought by the plaintiff, and where it shall appear that vacating said restraining order or denying said injunction will enable the defendant to consummate the threatened act, sought to be enjoined, before such appeal can be heard, so that the plaintiff will thereby be deprived of the benefits of any judgment of the appellate division, reversing the judgment of the lower court, then in such case the original restraining order granted in the case shall in the discretion of the trial judge be and remain in full force and effect until said appeal shall be finally disposed of: Provided, the plaintiff shall forthwith execute and deposit with the clerk a written undertaking with sufficient surety, approved by the clerk or judge, in an amount to be fixed by the judge to indemnify the party enjoined against all loss, not exceeding an amount to be specified, which he may suffer on account of continuing such restraining order as aforesaid, in the event that the judgment of the lower court is affirmed by the appellate division.
