As previously mentioned, the International Criminal Tribunals for the Former Yugoslavia (ICTY) and for Rwanda (ICTR) were created by the U.N. Security Council with limited lives for limited purposes.
In December 2010 the Security Council dealt with the problems associated with the limited lives of these two tribunals by creating The International Residual Mechanism for Criminal Tribunals (IRMCT). The Mechanism will have two branches for the just mentioned two tribunals after their closure. The branch for the ICTR will commence operations on July 1, 2012; the one for the ICTY, July 1, 2013.
The IRMCT’s two branches will prosecute and try those individuals who had been indicted, but not tried, by the ICTR and ICTY. For those “who are among the most senior leaders suspected of being most responsible for the crimes . . . considering the gravity of the crimes charged and the level of responsibility of the accused,” the authority of the IRMCT is unlimited. For lesser officials, it has a similar authority, but only “after it has exhausted all reasonable efforts to refer the case” to an appropriate national court.
The IRMCT also will have an appeals chamber to handle appeals from any trials that it conducts as well as trials conducted by the ICTR and ICTY, but that did have appeals lodged or completed when the two tribunals closed.
It is anticipated that the just-captured Ratko Mladic will be tried by the ICTY.
