Mixed agreement
An agreement between the EU and external countries concerning issues of Community and Member State competence - for example the Cotonou Agreement. Such agreements must be signed by both the EU and its Member States.
The Lisbon Treaty has established the Union as a legal personality (Art. 47 TEU). Itopens for mixed agreements on foreign policy and community topics. This is possible by conferring the legal personality upon the whole EU.
Hence, in areas where theĀ Union legislates, the EU can sign various kinds of agreements on behalf of the member states, who are consequently not allowed to negotiate international agreements on their own (autonomously) in these areas.
The so-called 'competence of external negotiation', has become a sole competence of the EU - member states will not be allowed to negotiate within this area on their own, unilaterally.
