NC RCP -- Rule 41. Dismissal of actions.
(a) Voluntary dismissal; effect thereof. –
(1) By Plaintiff; by Stipulation. – Subject to the provisions of Rule 23(c) and of any statute of this State, an action or any claim therein may be dismissed by the plaintiff without order of court (i) by filing a notice of dismissal at any time before the plaintiff rests his case, or; (ii) by filing a stipulation of dismissal signed by all parties who have appeared in the action. Unless otherwise stated in the notice of dismissal or stipulation, the dismissal is without prejudice, except that a notice of dismissal operates as an adjudication upon the merits when filed by a plaintiff who has once dismissed in any court of this or any other state or of the United States, an action based on or including the same claim. If an action commenced within the time prescribed therefor, or any claim therein, is dismissed without prejudice under this subsection, a new action based on the same claim may be commenced within one year after such dismissal unless a stipulation filed under (ii) of this subsection shall specify a shorter time.
