Montana Title 45. Crimes § 45-5-103. Mitigated deliberate homicide

(1) A person commits the offense of mitigated deliberate homicide when the person purposely or knowingly causes the death of another human being or purposely or knowingly causes the death of a fetus of another with knowledge that the woman is pregnant but does so under the influence of extreme mental or emotional stress for which there is reasonable explanation or excuse.  The reasonableness of the explanation or excuse must be determined from the viewpoint of a reasonable person in the actor's situation.

(2) Mitigated deliberate homicide is a lesser included offense of deliberate homicide as defined in 45-5-102(1)(a), but is not a lesser included offense of deliberate homicide as defined in 45-5-102(1)(b).

(3) Mitigating circumstances that reduce deliberate homicide to mitigated deliberate homicide are not an element of the reduced crime that the state is required to prove or an affirmative defense that the defendant is required to prove.  Neither party has the burden of proof as to mitigating circumstances, but either party may present evidence of mitigation.

(4) A person convicted of mitigated deliberate homicide shall be imprisoned in the state prison for a term of not less than 2 years or more than 40 years and may be fined not more than $50,000, except as provided in 46-18-219 and 46-18-222.
