Book excerpt: "The normative consolidation of the Area of Freedom, Security and Justice (AFSJ) and the entry into force of the Charter of Fundamental Rights of the EU (the Charter) has transformed the Union as we know it. It is common knowledge that the AFSJ has undergone impressive normative and jurisprudential developments in recent times. A plethora of new instruments has been adopted in the years following the entry into force of the Treaty of Lisbon, joining the already vast body of pre-Lisbon secondary law in the different fields covered by the AFSJ: civil and criminal judicial cooperation as well as matters related to borders, migration and asylum. By now, national authorities and courts have become or at least are becoming well acquainted with the AFSJ acquis, which is shown by the impressive increase of preliminary references made by national courts. It is today beyond any doubt that the AFSJ has become one of the most prolific areas of litigation before the Court of Justice of the European Union (CJEU)"--
