9.5. Administrative structure of the European Union: official titles and listing order

9.5.1. Institutions and bodies

The institutions and bodies must be listed in protocol order.

The following list indicates the official title, following protocol order since 1 December 2009 (entry into force of the Treaty of Lisbon). The list is followed by a table indicating the form of title to use according to the type of publication, along with the relevant abbreviation and the location of the seat.

See also Annex A9 – Institutions, bodies, interinstitutional services and organisations: multilingual list

(a) Institutions

European Council
President of the European Council
Court of Justice of the European Union
Court of Justice
General Court
The Civil Service Tribunal, established in 2004, ceased to operate on 1 September 2016 after its jurisdiction was transferred to the General Court.

(b) External policy body

European External Action Service
High Representative of the Union for Foreign Affairs and Security Policy
Three Councils
(do not get them confused)
In the European Union

Meetings of the Heads of State or Government (presidents or prime ministers) and the President of the European Commission take place, in principle, four times a year. These meetings are also known as ‘summits’. The European Council fixes the general political guidelines of the Union.

The ministers of the Member States meet regularly within the Council of the European Union. Depending on the issue on the agenda, each country will be represented by the minister responsible for that. It is the Union’s main decision-making body and determines the greater part of EU legislation.

Outside the European Union

The Council of Europe is an intergovernmental organisation but is not a European Union institution.

(c) Consultative bodies

(d) Other bodies

INSTITUTIONS AND BODIES – Different forms of title
Long name Short name (1) Abbre­viation Seat

The abbreviated form should only be used if there is no possibility of confusion (notably between ‘Court’ and ‘Committee’). The full expression must always be used at the first mention.
The seat of the Parliament is at Strasbourg. Additional sessions are organised at Brussels. The Secretariat is installed at Luxembourg.
The Commission has its seat at Brussels, but it has some services based in Luxembourg.
‘European Court of Auditors’ is the title in general use. However, the official title used in purely legal texts is ‘Court of Auditors of the European Union’ (before 1.12.2009: ‘Court of Auditors of the European Communities’), even if it is rarely found in texts. The short form ‘Court of Auditors’ is used in the Official Journal.
Do not use the short form ‘Economic and Social Committee’ or the abbreviation ‘CES’.
‘European Committee of the Regions’ is the name generally used. In purely legal texts and in the Official Journal, L series, use the official denomination ‘Committee of the Regions’. Acronym in use not to be changed (as requested by the Committee).
The seat of the Ombudsman is that of the European Parliament.

9.5.2. Interinstitutional services

The interinstitutional services are attached administratively to the European Commission (see also Section 9.6).

Agency Source/procedure
The reference act is in principle the founding act. If the latter has been ‘recast’ or a ‘codification’ of it has been made, or if it has been repealed and replaced by a new act, this modified act becomes the new reference act (the original founding act is then indicated in brackets as a reminder).

The different types of modification are as follows.

‘Corrigendum’, ‘amending act’ (or other): modifications to the basic act with regard to the name, the abbreviation or the seat.
‘Written form amended’: for the body in question, the written form used in the basic regulation has been amended in order to conform to the conventions of interinstitutional writing, in particular the rules relating to upper and lower case (with the agreement of the lawyer-linguists of the Council, no corrigendum is necessary).
Unique abbreviation for all linguistic versions.
