Treaty on the Functioning of the European Union

The Treaty on the Functioning of the European Union (TFEU) is one of two treaties forming the constitutional basis of the European Union (EU), the other being the Treaty on European Union (TEU; also referred to as the "Treaty of Maastricht"). It was previously known as Treaty Establishing the European Community (TEC). 
The Treaty originated as the Treaty of Rome (fully the "Treaty establishing the European Economic Community"), which brought about the creation of the European Economic Community (EEC), the best-known of the European Communities (EC). It was signed on 25 March 1957 by Belgium, France, Italy, Luxembourg, the Netherlands and West Germany and came into force on 1 January 1958. It remains one of the two most important treaties in the modern-day European Union (EU).
Its name has been amended twice since 1957. The Maastricht Treaty of 1992 removed the word "economic" from the Treaty of Rome's official title and, in 2009, the Treaty of Lisbon renamed it the "Treaty on the Functioning of the European Union".
Following the 2005 referenda, which saw the failed attempt at launching a European Constitution, on 13 December 2007 the Lisbon treaty was signed. This saw the 'TEC' renamed as the Treaty on the Functioning of the European Union (TFEU) and, once again, renumbered. The Lisbon reforms resulted in the merging of the three pillars into the reformed European Union.
In March 2011, the European Council adopted a decision to amend the Treaty by adding a new paragraph to Article 136. The additional paragraph, which enables the establishment of a financial stability mechanism for the Eurozone, runs as follows:
Present contents.
The consolidated TFEU consists of seven parts:
Part 1, Principles.
In principles, article 1 establishes the basis of the treaty and its legal value. Articles 2 to 6 outline the competencies of the EU according to the level of powers accorded in each area. Articles 7 to 14 set out social principles, articles 15 and 16 set out public access to documents and meetings and article 17 states that the EU shall respect the status of religious, philosophical and non-confessional organisations under national law.
Part 2, Non-discrimination and citizenship of the Union.
The second part begins with article 18 which outlaws, within the limitations of the treaties, discrimination on the basis of nationality. Article 19 states the council with the consent of the European Parliament "may take appropriate action to combat discrimination based on sex, racial or ethnic origin, religion or belief, disability, age or sexual orientation". Articles 20 to 24 establishes EU citizenship and accords rights to it; to free movement, consular protection from other states, vote and stand in local and European elections, right to petition Parliament and the European Ombudsman and to contact and receive a reply from EU institutions in their own language. Article 25 requires the commission to report on the implementation of these rights every three years.

The "Article 140" describes the criteria for inclusion in monetary union (the euro) or having exception from it, and also says that it is a majority of the council, not the state alone, which decides upon usage of euro or national currency. Thereby are states obliged (except UK and Denmark) to introduce the euro if the council finds they fulfil the criteria.
