The JSB takes its supervisory task very seriously and, therefore, not only meets regularly (at a minimum, four times a year) but also holds a yearly study visit as well as on-the-spot inspections.
The JSB holds frequent and regular inspections, covering both case-related and non-case-related (administrative) processing operations of Eurojust and delivers extensive and detailed reports of such inspections, including findings and recommendations, whose follow-up by the organisation is monitored in successive meetings. Where necessary, additional inspections dedicated to single matters or issues are held.
Normally, a full inspection (five inspectors/three days) is carried out every two years, with a follow-up visit the next year. In any case, the follow-up given to the recommendations of every report is monitored throughout the whole process until the following inspection. The inspections are led by a member of the JSB, accompanied by experts from the Data Protection Authorities of the Member States, and supported by the Data Protection Secretariat of the Council, to ensure an approach consistent with the inspections performed at Europol, the Schengen Information System and so forth. The involvement of experts from the National Data Protection Authorities is important, as the data held by Eurojust comes from the national authorities and will eventually be further used at national level again for investigations and prosecutions.
The importance of such inspections has been underlined many times at EU level. For instance, the Data Protection Catalogue on Cooperation and Supervision in the area of Law Enforcement in Europe, adopted by the Spring Conference of Data Commissioners 2009, in Edinburgh, provided a very substantial document dealing with inspection and supervision in the police and justice sector commonly carried out by the Data Protection Authorities, providing the following interesting remarks:
The need and importance for the cooperation and joint activities of national data protection authorities in the EU IIIrd pillar was emphasized by establishment of the joint supervisory authorities such as Schengen Joint Supervisory Authority, Europol Joint Supervisory Body, Eurojust Joint Supervisory Body, Customs Joint Supervisory Authority, in order to ensure joint independent control and monitoring of the data processing in the IIIrd pillar and protection of the rights of the individuals. Even when the Lisbon Treaty creating amendments of the existing EU Treaties will enter into force, this will not change the need for such cooperation. The experiences with the joint inspections of the use of the Schengen information system, the coordinated inspection of Eurodac, the joint inspections at Eurojust and Europol and the initiatives taken by the Europol Joint Supervisory Body demonstrate the added value of a common approach.
