The clerk shall, at the beginning of court, swear all jurors who have not been selected as grand jurors. Each juror shall take (i) the oath required by Section 7 of Article VI of the Constitution of North Carolina, by swearing or affirming to support and maintain the Constitution of the United States and the Constitution and laws of North Carolina not inconsistent therewith and (ii) the oath required under N.C. Gen. Stat. § 11-11, by swearing or affirming to truthfully and without prejudice or partiality try all issues in criminal or civil actions that come before the juror and give true verdicts according to the evidence. Nothing herein shall be construed to disallow the usual challenges in law to the whole jury so sworn or to any juror; and if by reason of such challenge any juror is withdrawn from a jury being selected to try a case, his place on that jury shall be taken by another qualified juror. The presiding judge shall decide all questions as to the competency of jurors. ?(1790, c. 321, P.R.; 1822, c. 1133, s. 1, P.R.; R.C., c. 31, s. 34; Code, s. 405; Rev., s. 1966; C.S., s. 2324; 1967, c. 218, s. 1; 2013-164, s. 1.)
