The Danish Military Prosecution Service has just posted a new edition of its excellent summary, The Danish Military Justice System. It is available here. The heart of the matter:
Military criminal cases are heard by the ordinary courts by a single judge or with lay judges or jurors depending on the severity and nature of the case. Military Courts were abolished in 1919. A District Court ruling may be subject to appeal to a High Court (Court of Appeal) and a judgment of that Court may – with a special permit from the Appeals Permission Board – be appealed to the Supreme Court.
A reform of the Military Criminal Justice System in 2005 separated the powers of the Military Prosecution Service from those of the military commanders. Military criminal cases are subject to the jurisdiction of the Military Prosecution Service only. The reform entered into force on 1 January 2006.
