The Lisbon Treaty came into effect on 1 December 2009 and made a number of important reforms to the constitution of the European Union. It is worth noting that one of its effects is to change the names of certain European institutions and the numbering of Treaty articles. In particular:
- The official name of the European Community is now the European Union. The abbreviation “EC” should be replaced by “EU” (although “EC” will remain in the citations of pre-existing directives and regulations).
- The European Court of Justice (ECJ) has been renamed the Court of Justice of the European Union (CJEU).
- The Court of First Instance has been renamed the General Court.
- In the context of European competition law, the provisions on the prohibition of restrictive agreements and abuse of dominance, formerly found in Articles 81 and 82 of the EC Treaty, are now found in Articles 101 and 102 of the Treaty on the Functioning of the European Union.
