A/HRC/23/46 to delay or frustrate the enforcement of the return decision; when protection of national security or public order so requires; or in accordance with A rticle 28 of the recast Dublin Regulation. Detention of asylum seekers in prisons is allowed, if no specialized detention facility is available, and the detention of unaccompanied children is allowed “in exceptional circumstances”. 110. The recast of the Dublin Regulation maintains the general rule that asylum applications shall be dealt with by the first country of entry into the EU. It includes some improvements, including the obligation to hold a personal interview and procedural safeguards on appeal. The establishment of an early warning, preparedness and crisis management mechanism envisaged under the recast Dublin Regulation article 33 is aimed at contributing to timely identification of protection gaps in EU Member States. 111. In 2014, the Commission will launch a comprehensive “fitness check” by conducting an evidence-based review covering the legal, economic and social effects of the Dublin system including its effects on fundamental rights (Commission Communication on enhanced intra EU solidarity in the field of asylum, COM(2011) 835 final). The Communication aims to develop solidarity in the field of asylum, based on the principles set out in the Communication. 112. In May 2012, the Commission presented a proposal for a recast of the EURODAC Regulation, which merges into a single regulation the proposed amendments for the better functioning of EURODAC, as well as a proposal for law enforcement access to EURODAC. The proposal provides that law enforcement authorities will be given access to EURODAC data, when national fingerprint databases return negative results and where the comparison is necessary for the purpose of the prevention, detection or investigation of terrorist offences or other serious criminal offences; the comparison is necessary in a specific case; and there are reasonable grounds to consider that such comparison with EURODAC data will contribute to the prevention, detection or investigation of any of the criminal offences in question. Additionally, Europol may make requests for comparison with EURODAC data within the limits of its mandate and where necessary for the performance of its tasks and for the purposes of a specific analysis or an analysis of a general nature and of a strategic type. 2. The Refugee Fund 113. The European Refugee Fund was established by Decision No 573/2007/EC of the European Parliament and of the Council, as part of the General programme “Solidarity and Management of Migration Flows”. It has provided EUR 630 million over the period 200813. It aims to ensure solidarity and responsibility sharing within the EU, and supports actions relating to reception conditions and asylum procedures; integration measures; enhancement of Member States ’ capacity to develop, monitor and evaluate their asylum policies; and resettlement. The Refugee Fund will be absorbed by the future Asylum and Migration Fund. 3. The European Asylum Support Office (EASO) 114. The Hague Programme proposed the establishment of a European Asylum Support Office. EASO was created by Regulation (EU) 439/2010 of the European Parliament and of the Council, and inaugurated in 2011. It plays a key role in the development of the Common European Asylum System. It was established with the aim of enhancing cooperation on asylum matters and helping Member States fulfil their European and international obligations to protect people in need. EASO acts as a centre of expertise on asylum, and provides support to Member States whose asylum and reception systems are under particular pressure. 42
