The respondent has a right, upon request by him, his counsel, or his guardian ad litem, to trial by jury. Failure to request a trial by jury shall constitute a waiver of the right. The clerk may nevertheless require trial by jury in accordance with G.S. 1A-1, Rule 39(b), Rules of Civil Procedure, by entering an order for trial by jury on his own motion. The jury shall be composed of 12 persons chosen from the county's jury list in accordance with the provisions of Chapter 9 of the General Statutes. (1987, c. 550, s. 1.)
