EU policies aim to maintain and further develop the Union as an area of freedom, security and justice. On issues such as border control, visas, external migration, asylum, police cooperation, the fight against organised crime and against terrorism, cooperation in the field of drugs, customs cooperation and judicial cooperation in criminal and civil matters, Member States need to be properly equipped to adequately implement the growing framework of common rules. Above all, this requires a strong and well-integrated administrative capacity within the law enforcement agencies and other relevant bodies, which must attain the necessary standards. A professional, reliable and efficient police organisation is of paramount importance. The most detailed part of the EU’s policies on justice, freedom and security is the Schengen acquis, which entails the lifting of internal border controls in the EU. However, for the new Member States substantial parts of the Schengen acquis are implemented following a separate Council Decision to be taken after accession.
