Implementation of the Treaty of Lisbon
Amendments to apply from 1 December 2009

The entry into force of the Treaty of Lisbon on 1 December 2009 entails several important amendments.

Treaties The Treaty establishing the European Community is replaced by the Treaty on the Functioning of the European Union. The concepts ‘European Community’/‘European Communities’ are replaced by ‘European Union’. Exception: the expression ‘European Community’ remains unchanged when concerning the Treaty establishing the European Atomic Energy Community. Consequently, the adjective ‘Community’ must be replaced by ‘Union’ or an appropriate phrase, except in a context that only concerns Euratom. Example: ‘non-Community currencies’ is replaced by ‘third-country currencies’. It is necessary to take into account the historical aspect of published texts. (The terms ‘European Community’, ‘European Communities’ or ‘Community’ remain in application for texts relating to the period before 1 December 2009.) Abbreviations Treaty establishing the European Community (TEC) Treaty on European Union (TEU) Treaty on the Functioning of the European Union (TFEU) (The rules concerning the abovementioned abbreviations are still to be established.)
