In its Judgement issued on 30 November 2005 in Prosecutor v. Limaj et al., Trial Chamber II of the ICTY found that an armed conflict existed in Kosovo between the Kosovo Liberation Army and the Serbian forces as of the end of May 1998. It held, however, that the evidence did not establish that there was a widespread or systematic attack by the KLA directed against a civilian population at the relevant time. The first trial of former members of the Kosovo Liberation Army also gave rise to a number of significant developments in the ICTY's jurisprudence relating to issues of international criminal law and procedure, such as the treatment of hostile witnesses and of eyewitness identification evidence, as well as the proof of the existence of a joint criminal enterprise.
