Prosecutor v. Krajisnik (2005-2006)

Momcilo Krajisnik was a member of the Bosnian Serb leadership during the Bosnian civil war (1992-1995). In essence it was alleged that he was the second most powerful and influential Serb politician in the Republika Srpska after Radovan Karadzic and that the two of them ran their self-proclaimed state in tandem. The indictment dealt with crimes committed throughout much of 1992 in 37 of the 109 municipalities of Bosnia-Herzegovina. In order to put the events of 1992 into context, the case dealt extensively with the political events in Bosnia from the advent of the multi-party system in 1990 to the outbreak of the war in Spring 1992, when the crimes alleged began to take place. The trial transcript ultimately amounted to in excess of 27,000 pages. Krajisnik was acquitted of genocide, but was convicted of various crimes the most significant of which being extermination, murder (of approximately 3000 persons) and persecutions. Some of these convictions including extermination and murder were in turn quashed on appeal.

Prosecutor v. Popovic et al (2006-2010)

Represented Milan Gvero in this seven defendant case. The trial which lasted in excess of three years was the largest war crimes trial in terms of the number of accused persons since Nuremberg. The case involved the events surrounding the Srebrenica massacre in July 1995, the worst massacre in Europe since the Second World War, where approximately 8,000 Muslim men were allegedly murdered by soldiers from the Bosnian Serb army. Gvero faced charges of murder, persecutions, forcible transfer and deportation. He was the most senior officer on trial having been a Lieutenant General at the material time. In June 2010 he was acquitted of a number of the charges including murder and received a sentence of only 5 years imprisonment which resulted in his immediate release for time served.
