Specialist Prosecutor v. Mustafa (Kos. Specialist Chambers)

On December 14, 2023, the Appeals Panel of the Kosovo Specialist Chambers (KSC) delivered its judgment in its first war crimes case against Salih Mustafa, a former commander of the Kosovo Liberation Army (KLA), charged with leading a guerrilla unit known as the “BIA” unit Zllash, in the Gollak region of Kosovo. Mustafa was charged by the Specialist Prosecutor's Office (SPO) with war crimes, including arbitrary detention, cruel treatment, torture, and murder, in connection with the mistreatment of prisoners at a makeshift detention facility in Zllash in April 1999. The Appeals Judgment affirmed Mustafa's convictions for arbitrary detention, torture, and murder as war crimes, but granted his appeal, in part, against his sentence. The Appeals Panel lowered Mustafa's single sentence from twenty-six to twenty-two years of imprisonment, concluding that this reflected the totality of Mustafa's criminal conduct in this case. The sentence was subject to further review and determination by the Appeals Panel pursuant to the Supreme Court Panel's subsequent decision on protection of legality, wherein that Panel granted Grounds 1 and 3 of the Mustafa's Protection of Legality Request. The Supreme Court Panel annulled the Appeals Judgment with respect to Mustafa's sentence, and it remanded the Appeals Judgment to the Appeals Panel for a new determination thereon. Accordingly, the Appeals Chambers Panel made a new determination of the sentence, by imposing a single sentence of fifteen years of imprisonment on Mustafa. These Trial and Appeals judgments mark a milestone for the Kosovo Specialist Chambers (KSC), as they represent the first ruling by this tribunal in a war crimes case.
