Montana Title 46. Criminal Procedure § 46-1-401. Penalty enhancement--pleading, proof, and mental state requirements

(1) A court may not impose a penalty enhancement specified in Title 45, Title 46, or any other provision of law unless:

(2) The enhancement issue may be submitted to a jury on a form separate from the verdict form or may be separately stated on the verdict form. The jury must be instructed that it is to reach a verdict on the offense charged in the information, complaint, or indictment before the jury can consider whether the enhancing act, omission, or fact occurred.

(3) An enhancing act, omission, or fact is an act, omission, or fact, whether stated in the statute defining the charged offense or stated in another statute, that is not included in the statutory definition of the elements of the charged offense and that allows or requires a sentencing court to add to, as provided by statute, a penalty provided by statute for the charged offense or to impose the death penalty instead of a statutory incarceration period provided by statute for the charged offense. Except as provided in subsection (4), the aggravating circumstances contained in 46-18-303 are enhancing acts, omissions, or facts.

(4) Use of the fact of one or more prior convictions for the same type of offense or for one or more other types of offenses to enhance the penalty for a charged offense is not subject to the requirements of this section.
