CO-DECISION or the "ordinary legislative procedure"

This site provides information on co-decision or the "ordinary legislative procedure" as it is known with the entry into force of the Lisbon Treaty (Article 294 of the Treaty of the Functioning of the European Union (TFEU)). It also looks at the roles played therein by the three institutions (European Parliament, Council, and Commission).

The site will provide you with information on the procedure itself (including references to the Treaty, the relevant legal bases pdf - 102 KB [102 KB] , a practical guide called "co-decision step by step"), and on all the legislative files being dealt with at the different stages in the procedure or which have been adopted.

There are also useful links to the sites of the co-legislators (European Parliament and Council), which provide additional information. For any additional questions, please refer to the relevant contacts.


Vice President - Commissioner for Inter-Institutional Relations and Administration.

"With the Lisbon Treaty, the ordinary legislative procedure which brings together Council, Parliament and Commission has become the standard way of decision-making. Through this partnership between the institutions, the common interests of the European Union, of its Member States and its citizens are expressed in a unique and tangible way, creating the necessary legislation to meet the challenges of the future."
