The right of interim release during trial is an international recognized fundamental right of the accused which is deduced from the presumption of innocence. Although the ICTY has shifted to a more liberal practice, the other tribunals and the ICC are still applying the law of interim release in a restrictive manner. Decisions on interim release are not guided by clearly decisive factors to be applicable for every single accused in each case. Rather an examination of the particular facts of the case and the personality or character of the accused, surrounded by a framework of requirements set forth in the Rules of Procedure and Evidence, determine the practice on interim release. The way international criminal tribunals apply the law of interim release is, like international criminal proceedings as such, of a design sui generis. This article summarises the case-law concerning interim release at the international criminal tribunals. It gives an in-depth study on the requirements set forth in the Rules of Procedure and Evidence which the accused must fulfil to be provisional released.
