There are no defence commitments for Ireland under the Treaties establishing the European Communities or the Single European Act. This position will not change under the Maastricht Treaty on European Union. The European Union will not be empowered, under the Treaty's provisions, to act in the defence area.
Discussions and decisions on the scope and content of a common defence policy and on the question of a common defence for the Union are left to a future negotiation and another intergovernmental conference to take place in 1996. The outcome of that negotiation will require the unanimous approval of all the member states. It is very likely that the outcome of such a negotiation, if it is of any substance, could not be ratified here without a constitutional amendment and the Taoiseach accordingly has stated that a further referendum will be necessary at that point in relation to any proposals which emerge.
The Maastricht Treaty establishes a relationship between the European Union and the Western European Union, WEU, which is set out in Article J.4 of the Chapter on the Common Foreign and Security Policy. Under this Article, the Union requests the Western European Union, which is described as an integral part of the development of the European Union, to elaborate and implement decisions and actions of the Union which have defence implications.
