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 of any claim that the plaintiff has once dismissed in any court.
Ohio. Civ.R. 41
Staff Note (July 1, 2001 Amendment)
Civil Rule 41 Dismissal of Actions
This rule was amended (1) to reflect more precisely its interpretation by the Supreme Court in Denham v. City of New Carlisle, 86 Ohio St. 3d 594 (1999); (2) to conform Civ. R. 41(D) with Civ. R. 41(A) as amended; and (3) to reflect that Civ. R. 23.1 provides that a shareholder derivative action "shall not be dismissed or compromised without the approval of the court."
In divisions (B) and (C), masculine references were changed to gender-neutral language, the style used for rule references was changed, and other grammatical changes were made. No substantive amendment to divisions (B) and (C) was intended.
