Conference of Parliamentary Committees for Union Affairs

The Conference of Parliamentary Committees for Union Affairs of Parliaments of the European Union (COSAC) is a conference of Members of the European Parliament (MEPs) and national Members of Parliament (MPs) who are drawn from parliamentary committees responsible for European Union affairs.

History and role


COSAC was founded in 1989 on a proposal of Laurent Fabius, then President of the French National Assembly and at the same time an MEP on the European Parliament Committee on Constitutional Affairs (AFCO). COSAC meets twice a year in the member state that holds the rotating Presidency of the Council of the European Union.

The conference is mainly intended for personal contacts between Members of National Parliaments and MEPs, and for exchanges of information. The conference is therefore interested in the means by which the parliaments are able to co-operate and communicate with each other via interparliamentary meetings, and through the IPEX scrutiny website. The 17 Biannual COSAC report from April 2012 focused on recent developments in parliamentary scrutiny and the parliaments' use of IPEX.

COSAC may also adopt contributions addressed to the EU institutions. COSAC has gained the right to submit contributions and examine proposals on EU law relating to Justice and Home Affairs and saw its role further expand under the Treaty of Lisbon with provisions for increased involvement of national parliaments in EU affairs.

Various committees from non-EU countries have also been invited to participate in the meetings as observers. For example, on 26 November 2023, the Standing Committee on European Integration representing Armenia participated in the COSAC meeting held in Madrid, Spain.

Name
COSAC is a French acronym for the conference's former name "Conférence des organes spécialisés dans les affaires communautaires et européennes des parlements de l'Union européenne" (Conference of Community and European Affairs Committees of Parliaments of the European Union). It is known by similar terms such as the Conference of European Community Affairs Committees and under the Treaty of Lisbon COSAC's name is listed as the conference of Parliamentary Committees for Union Affairs.
