N.C. Gen. Stat. § 8-81: Objection to deposition before trial.

At any time before the trial, or hearing of an action or proceeding, any party may make a motion to the judge or court to reject a deposition for irregularity in the taking of it, either in whole or in part, for scandal, impertinence, the incompetency of the testimony, for insufficient notice, or for any other good cause. The objecting party shall state his exceptions in writing. (1869-70, c. 227, ss. 13, 17; Code, s. 1361; 1895, c. 312; 1903, c. 132; Rev., s. 1648; C.S., s. 1819.)
