A joint investigation team (JIT) is one of the most advanced tools used in international cooperation in criminal matters, comprising a legal agreement between competent authorities of two or more States for the purpose of carrying out criminal investigations. Made up of prosecutors and law enforcement authorities as well as judges, JITs are established for a fixed period, typically between 12 and 24 months, such as is necessary to reach successful conclusions to investigations.
Providing operational, legal and financial support to JITs is a key part of Eurojust’s mission, together with enabling access to the expertise of the JITs Network, a network of relevant national experts, who encourage and promote best practice in the use of JITs. Eurojust also hosts the JITs Network Secretariat, which supports and stimulates the activities of the JITs Network. Since 2005, the Agency has supported national authorities in the setting up and running of JITs, and has provided funding from 2009, while also taking a leading role in promoting JITs and developing awareness and understanding around the tool and its use.
