Parties to a lawsuit generally have an absolute right to nonsuit (dismiss) their own claims for relief at any time during the litigation until they have introduced all evidence other than rebuttal evidence at trial.
In Iowa, parties to a lawsuit have the right to voluntarily dismiss their own claims, which is often referred to as a nonsuit. This right is typically absolute and can be exercised at any point during the litigation process until the party has presented all of its evidence, except for rebuttal evidence, at trial. This means that a plaintiff can decide to dismiss their case without prejudice, allowing them the possibility to refile the case in the future, as long as they do so before they rest their case at trial. The relevant rules governing voluntary dismissal in Iowa are found in the Iowa Rules of Civil Procedure. However, there may be certain conditions or limitations on this right, such as court approval or conditions set by the court, especially if the dismissal occurs after the defendant has filed a counterclaim or if the dismissal could affect the rights of other parties involved in the litigation.
