STOP PRESS: On 23 June 2016, the UK held a referendum on its membership of the EU, with a majority voting in favour of the UK leaving the EU. The full impact of Brexit remains to be established but the UK will remain an EU Member State, fully subject to EU law, until the moment that it leaves. We are reviewing our content on the basis of information available and will keep it under regular review throughout the withdrawal period. In the meantime, for background reading, links to related guidance and policy documents, plus the latest analysis on the potential impact on our content, please refer to our Brexit overview, see: Brexit—overview.

The amendment of the EU Treaties is essential for the development of the European Union (EU). It allows EU legislation and policies to be adapted to the new challenges that the EU has to face or simply to further develop the degree of integration achieved. Before the entry into force of the Lisbon Treaty there was only one procedure for the revision of the Treaties. It required an Intergovernmental Conference (IGC), a conference of representatives of the governments of the member state convened by the President of the Council, to be convened on a compulsory basis.TEU, art 48.4

It must be mentioned that considering the long time it took for the Lisbon Treaty to be agreed (the amendment to the Treaties was envisaged as necessary since 2001—leaving aside the failed Constitutional Treaty) its drafters decided to make possible, in the years to come, minor amendments to the Treaties without the need of an IGC.

The Lisbon Treaty slightly amended
