On 19 May 2010, the Spanish Minister for the Interior, Alfredo Pérez Rubalcaba and the President of the European Parliament, Jerzy Buzek, signed the Regulation establishing the European Asylum Support Office. This Regulation allows the creation of a new European regulatory agency into the EU institutional landscape. The Office, a fledgling agency, is one of the active agencies in the home affairs sector: FRONTEX, the Monitoring Centre for Drugs and Drug Addiction, EUROPOL, CEPOL and EUROJUST. The founding regulation of the Office is the first legal instrument, adopted as part of legislative proposals recently introduced by the European Commission in the asylum area. This allows an old project to achieve its purpose, by creating a structure primarily designed to support Member States of the European Union in their efforts to bring closer national practices in the field of asylum. If EASO’s founding Regulation can meet this first concern of the Member States, it can also in many ways be considered as a breakthrough in European law, from an institutional, as well as from a substantive point of view. This article intends to examine these elements.
