The act incorporates the federal "Uniform Code of Military Justice" (federal code) into the "Colorado Code of Military Justice" (state code), including specifically the punitive articles and general article of the federal code, which describe punishable offenses, and the statute of limitations that applies to charges brought pursuant to the state code. The act repeals sections of the state code that are duplicative of the incorporated federal code. Additionally, the act: Applies the state code to a member of the state military forces (member) at all times, except when the member is ordered to active federal service pursuant to title 10 of the United States Code; Clarifies a commanding officer's authority to impose nonjudicial punishment under the state code; Makes changes to the procedures that govern courts-martial, the punitive authority of courts-martial, and the review of the decisions of courts-martial; and If concurrent civilian and military jurisdiction exists over the same offense and a district attorney has filed felony charges against a member for the offense, requires the state military forces to defer felony prosecution of the member to the district attorney.(Note: This summary applies to this bill as enacted.)
