Under the Lisbon Treaty, national parliaments were given a number of new rights and powers.
Article 12 of the Treaty on European Union (TEU) and Protocol No 1 give them the right to receive information directly from the EU institutions on legislative programmes, consultative documents, Council minutes, etc., in addition to EU legislative acts.
Article 5 TEU and Protocol No 2 give them the right to object to EU acts on the basis of subsidiarity by means of a system of yellow (Article 7(2) of Protocol No 2) and red (Article 7(3) of Protocol No 2) cards. Under Article 8 of Protocol No 2, EU countries can ask the Court of Justice of the EU to review the legality of EU acts.
In the area of freedom, security and justice (AFSJ), under Article 70 of the Treaty on the Functioning of the European Union (TFEU), parliaments must be kept informed of the evaluation system of EU countries’ implementation of AFSJ policies. Articles 85 and 88 TFEU permit their scrutiny of Eurojust and Europol activities.
Article 48 TEU and Article 81 TFEU allow for the use of general and specific passerelle clauses. These permit the legislative procedure normally used to be altered under certain specific conditions.
