with agreement of the College). As Eurojust is tasked with facilitating the execution of letters rogatory and extradition requests, it also may act on European Arrest Warrants (EAW). When more than one EAW exists for one individual, Eurojust may advise the judicial authority that executes the EAW which should take priority and may also facilitate communication between the judicial authorities involved. It is also the body to which member states may report delays in execution of EAWs of the reason for such delay. In 2010, a total of 280 cases concerning the execution of EAWs were registered at Eurojust, amounting to almost 20 per cent of all cases. Eurojust may also take part in a joint investigation team (JIT) or, on request of a member state, help establish one and/or assist in managing one administratively or by securing funding. Such teams are created on the agreement of two or more involved parties for a specific purpose and limited time to carry out criminal investigations in one or more of the member states involved. JITs were established on the belief that cross-state teams of investigators and judicial authorities with clear legal authority and defined roles would improve the fight against organised crime. Caseload Eurojust has handled an increasingly heavy caseload since its creation. In 2002, it was contacted in 202 cases. In 2016, member states sought assistance with 2,306 new cases.

Eurojust also organised 249 co-ordination meetings between representatives of national authorities and EU bodies in 2016. Administration The College of Eurojust is supported by the administration. As head of the Eurojust administration, the Administrative Director is responsible for the day-to-day management of Eurojust, including budget and staff management. The administrative organisation is composed of units, services and secretariats: the Accounting Office, Budget, Finance and Procurement Unit, College Secretariat, Corporate Communications Office, Data Protection Service, Events and Logistics Office, Human Resources Unit, Information Management Unit, Institutional Affairs Office, Legal Affairs Office, Operations Unit, Planning, Programming & Reporting Office and Security, Facility & General Services. Future developments The Treaty on the Functioning of the European Union addresses several changes to Eurojust. Article 85 extends its scope to including serious crime not only affecting two or more member states, but also requiring prosecution on a common basis. The new wording of the Treaty mentions that
