• An action based on intentional conduct brought by a person for recovery of damages for injury suffered as a result of childhood sexual abuse against the individual who committed the acts (i.e., any act committed against a plaintiff who was less than 18 years of age and that would have been a violation of § 45-5-502, 45-5-503, 45-5-504, 45-5-507, 45-5-508,  45-5-625, 45-5-627, 45-5-702, 45-5-705 or 45-5-706) must be commenced (1) before the victim of the act of childhood sexual abuse that is alleged to have caused the injury reaches 27 years of age; or (2) not later than three years after the plaintiff discovers or reasonably should have discovered that the injury was caused by the act of childhood sexual abuse.

• Exception: A claim for damages described in the paragraph above that would otherwise be barred because the applicable statute of limitations has expired may be commenced within 1 year of May 7, 2019 if the individual who committed the act of childhood sexual abuse against the plaintiff is alive at the time the action proceeds or is commenced and: (1) has admitted to the commission of such act against the plaintiff in either a written and signed statement or a statement recorded by audio or video; or (2) (i) has made one or more statements admitting to the commission of such act against the plaintiff under oath or in a plea agreement; or (ii) has been convicted of an offense of “childhood sexual abuse” in which the plaintiff was the victim.

• An action for recovery of damages for liability against any entity that owed a duty of care to the plaintiff, where a wrongful or negligent act by an employee, officer, director, official, volunteer, representative, or agent of the entity was a legal cause of the childhood sexual abuse that resulted in the injury to the plaintiff, the action must be commenced: (1) before the victim of the act of childhood sexual abuse that is alleged to have caused the injury reaches 27 years of age; or (2) not later than 3 years after the plaintiff discovers or reasonably should have discovered that the injury was caused by the act of childhood sexual abuse.

• Exception: (a) A claim for damages described in the paragraph above that would otherwise be barred because the applicable statute of limitations has expired must be revived if the court concludes that the entity against whom the action is commenced, based upon documents or admissions by employees, officers, directors, officials, volunteers, representatives, or agents of the entity, knew, had reason to know, or was otherwise on notice of any unlawful sexual conduct by an employee, officer, director, official, volunteer, representative, or agent and failed to take reasonable steps to prevent future acts of unlawful sexual conduct. (b) A cause of action in which allegations described in (a) above are made but that would otherwise be barred by the statute of limitations in the paragraph above may be commenced within 1 year of May 7, 2019.

• Tipton v. Montana Thirteenth Judicial District Court, 421 P.3d 780 (Mont. 2018) (holding that the statute permitting a prosecution for certain sex offenses to “be commenced within 1 year after the suspect is conclusively identified by DNA testing” if the suspect is so identified after the expiration of the limitations period violates the Ex Post Facto Clauses of the United States and Montana Constitutions when applied to cases in which the limitations period expired before the statute came into effect).
