Vidoje Blagojević was the commander of the Bratunac Brigade of the Bosnian Serb Army during the attack on Srebrenica. His unit surrounded one side of the city, and both supported and participated in the military action. Blagojević was another who was initially found guilty of genocide-related crimes, but then acquitted of them on appeal. The ICTY reduced his sentence from 18 to 15 years, while still finding him guilty of murder, persecutions, and inhumane acts as war crimes.
It was not only in cases surrounding the Srebrenica genocide that high-profile convictions were reversed on appeal. Croatian generals Ante Gotovina and Mladen Markač also successfully appealed their convictions for crimes against Serbs in Croatia (Orentlicher, Some Kind of Justice). Victims’ disappointed and distraught reactions to these decisions highlight the difficult position of international criminal tribunals in general: if the odds are stacked against defendants, trails will be unfair at best and a farce at worst, but, if defendants are granted too many rights and protections, even barely controversial legal decisions might be difficult to reach.
In Blagojević’s case, and to a certain extent Radislav Krstić’s as well, the courts eventually found reasons to doubt they had acted with genocidal intent because they merely provided resources to the parties that actually committed the crimes. Blagojević’s appeal was upheld because his “knowledge of the principal perpetrators’ genocidal intent” couldn’t be proven (even given everything else he knew about killings and forcible separations of men from women and children). Legal scholars argue over these cases, which call into question the precise requirements for determining innocence and guilt in the context of genocide.
