COREPER I

COREPER I (from the French Comité des représentants permanents, Part I) is the lower-ranking of the two formations of the Committee of Permanent Representatives that prepares the work of the Council of the European Union. Its legal foundation rests on Article 240(1) of the Treaty on the Functioning of the European Union (TFEU), which stipulates that "a committee consisting of the Permanent Representatives of the Governments of the Member States shall be responsible for preparing the work of the Council." The bifurcation into COREPER I and COREPER II is not laid down in the Treaties themselves but in the Council's Rules of Procedure (Council Decision 2009/937/EU, as amended) and reflects a working division established progressively from 1962 onward to manage growing legislative volume. COREPER I is composed of the Deputy Permanent Representatives of the 27 member states, each holding ambassadorial rank and accredited to the EU in Brussels, and is chaired by the deputy permanent representative of the member state holding the rotating six-month Council presidency.

The procedural mechanics of COREPER I follow a tightly choreographed weekly cycle. The committee meets every Wednesday and Friday in the Justus Lipsius or Europa buildings in Brussels, with agendas circulated by the presidency through the Council's General Secretariat. Files arrive at COREPER I after passing through one of roughly 150 Council working parties — composed of national experts and chaired by presidency officials — which negotiate the technical substance line by line. When a working party reaches the limits of what experts can resolve, the file is escalated to COREPER I with outstanding political questions flagged in an "I/A" or "II" item note. Items listed under "Part I" of the agenda are deemed agreed and require no discussion; "Part II" items are taken up substantively, with deputy permanent representatives negotiating compromises drafted by the presidency in consultation with the Council Legal Service and the Commission's representative present in the room.

COREPER I covers the dossiers handled by six Council configurations: Employment, Social Policy, Health and Consumer Affairs (EPSCO); Competitiveness (COMPET); Transport, Telecommunications and Energy (TTE); Agriculture and Fisheries (AGRIFISH); Environment (ENVI); and Education, Youth, Culture and Sport (EYCS). This portfolio is overwhelmingly the domain of the ordinary legislative procedure under TFEU Article 294, meaning COREPER I deputies routinely conduct trilogue negotiations with the European Parliament and the Commission, armed with a negotiating mandate adopted by the Council. The Antici and Mertens groups — small clusters of personal assistants to permanent and deputy representatives respectively — meet the day before each COREPER session to confirm agendas, signal national positions, and reduce the scope of formal discussion. The Mertens group specifically prepares COREPER I, while the Antici group prepares COREPER II.

In contemporary practice, COREPER I has been the locus of negotiation on files of major economic and regulatory weight. During the Czech presidency in the second half of 2022, COREPER I finalised Council positions on the Carbon Border Adjustment Mechanism and the revision of the EU Emissions Trading System under the Fit for 55 package. The Swedish presidency in spring 2023 saw COREPER I broker the politically sensitive compromise on CO₂ emission standards for cars after a late objection from Berlin's transport ministry on e-fuels. The Belgian presidency in the first half of 2024 used COREPER I to land the Net-Zero Industry Act and the Critical Raw Materials Act. Deputy permanent representatives in this period included figures such as France's Philippe Léglise-Costa and Germany's Susanne Szech-Koundouros, whose interventions shaped outcomes well beyond their formal mandates.

COREPER I should be distinguished from COREPER II, which is composed of the permanent representatives themselves (full ambassadors) and prepares the General Affairs, Foreign Affairs, Economic and Financial Affairs (ECOFIN), and Justice and Home Affairs Council configurations, as well as the multiannual financial framework and enlargement files. The split is one of subject matter and political weight rather than hierarchy: COREPER II handles questions of "high politics," while COREPER I concentrates on the regulatory and technical acquis. COREPER I is also distinct from the Special Committee on Agriculture (SCA), which under a 1960 Council decision prepares AGRIFISH files relating to the Common Agricultural Policy, bypassing COREPER for that specific portfolio, though fisheries files still pass through COREPER I.

Edge cases and controversies attach to the committee's quasi-legislative weight. Roughly 70 to 80 percent of Council acts are agreed at COREPER level and adopted by ministers without debate as "A items," a practice criticised by transparency advocates and the European Ombudsman, notably in Strategic Inquiry OI/2/2017/TE, which found maladministration in the Council's failure to record member state positions at preparatory level. The Court of Justice in Access Info Europe v. Council (Case C-280/11 P, 2013) ordered fuller disclosure of working-party documents. Recent developments include increased use of written procedures and videoconferencing introduced during the COVID-19 period and retained for technical exchanges, and the integration of cohesion and recovery files under the Recovery and Resilience Facility into COREPER I's regulatory workload from 2021.

For the working practitioner — desk officer in a foreign ministry, Brussels-based attaché, or Commission official — COREPER I is the level at which national instructions must be translated into operational red lines and at which trilogue mandates are won or lost. Mastery of its rhythm, of the Mertens group's signalling conventions, and of the presidency's compromise-drafting habits is the difference between shaping EU legislation and merely observing it.
