Revised Statues - Chapter 25 Courts, District; Civil Procedure

The court may determine any controversy between parties before it when it can be done without prejudice to the rights of others or by saving their rights; but when a determination of the controversy cannot be had without the presence of other parties, the court must order them to be brought in. Any person whose negligence was or may have been a proximate cause of an accident or occurrence alleged by the plaintiff, other than parties who have been released by the plaintiff and are not subject to suit pursuant to section 25-21,185.11, may be brought into the suit by any defendant in the manner provided in section 25-331 or by any plaintiff in the manner provided in sections 25-849 and 25-852.
