The International Criminal Tribunal for the former Yugoslavia (ICTY) found that those units were deployed to Herzegovina following an order issued by Sefer Halilović.
According to ICTY, the evidence showed that members of both brigades not only demonstrated a lack of discipline, but also committed different forms of misappropriation (thefts etc.)
The Trial Chamber noted in this respect the testimony of the 1st Corps Commander, Vahid Karavelić, who, while knowing of breaches of discipline and previous behaviour of members of these brigades, said that it never occurred to him that they might commit atrocities against civilians in Grabovica.
[4] The ICTY established that by the early afternoon of 9 September, a number of inhabitants had been murdered by members of the ARBiH units present in Grabovica at the time.
The ICTY found that based on the evidence, it could not be concluded that Sefer Halilović had the material ability to punish the perpetrators of the crimes committed in Grabovica.
