the ability of a party whose case has been dismissed to refile it with the court, usually after overcoming the issue that led to its dismissal. If a case is dismissed with prejudice it may not be refiled; if it is dismissed without prejudice, the plaintiff (civil) or prosecutor (criminal) is permitted to refile if they so wish.
In law, the phrase without prejudice means that a claim, lawsuit, or proceeding has been brought to a temporary end but that no legal rights or privileges have been determined, waived, or lost by the result. For example, if a party brings a lawsuit in small claims court but discovers that the claim is greater than the amount for that court to have jurisdiction, the lawsuit can be dismissed "without prejudice". This means that the dismissal is no bar to bringing a new lawsuit in a court that does have jurisdiction.
