Cooperation in extradition and judicial assistance in criminal matters

31-03-2014 Legal Fact Sheet

The repression of violations of international humanitarian law often requires the cooperation of different States, not only because the persons involved in the trials (the accused, the victims, the witnesses, etc.) may be of different nationalities, or in different countries, but also because the most serious violations of international humanitarian law are considered to affect the international community as a whole. Cooperation between States is also essential where the evidence relating to such crimes is located in a State other than the prosecuting State, or in several different countries.
