  Thus, the ICTY has been able to convict Serbian officers for war crimes because they did not prevent or curtail activities in which their troops were engaged. In an especially striking expansion of CR, a Bosnian Croat regional commander, Tihomir Blaskic, was convicted by the trial chamber of the ICTY of murder and other crimes against humanity, for atrocities that took place in the village of Ahmichi. The charges did not allege direct involvement or even turning a blind eye to the activities of subordinates, but, rather, focused on Blaskic's failure to investigate after the massacre was brought to his attention. His unwillingness to look into the events was equated by the court with responsibility for direct killing. In 2004 the appeals chamber of the ICTY rejected this interpretation of CR and overturned the relevant part of the conviction.
