Danish Opt-Out on Defense (Maastricht Treaty)
Protocol (No 5) to the Maastricht Treaty on European Union on the position of Denmark (1997) - Article 6
As regards the measures adopted by the Council in the field covered by Article 13(1) and Article 17 of the Treaty on European Union, Denmark does not participate in the preparation and implementation implementation of decisions and actions of the Union which have defense implications, but it will not prevent the development of closer cooperation between Member States in this area. Denmark is therefore not taking part in their adoption. Denmark is not obliged to contribute to the financing of operational expenditure resulting from these measures.
