The use of joint criminal enterprise as an actual criminal investigation and prosecution theory first appeared at the ICTY through a written proposal to Chief Prosecutor Carla Del Ponte which had been developed and authored by American prosecutor Dermot Groome (at the time, the legal officer for the Bosnia case) and American Investigator John Cencich, head of the Milosevic investigation for crimes allegedly committed in Croatia. (Cencich provides an in-depth look at the actual development of the investigation and prosecution theory of the JCE in his doctoral dissertation at the University of Notre Dame, in the
International Criminal Justice Review, and in his book, ''The Devil's Garden: A War Crimes Investigator's Story''.)
Indictments to Serb leaders The ICTY prosecutor indicted
Slobodan Milošević on three separate indictments which, upon appeal, were successfully considered as one indictment. As the prosecution had not used the same language in all three indictments, it was left to the Court of Appeal to decide if the alleged criminal enterprises in the three indictments were the same by determining what was common between the allegations. The ICTY Appeals count decided that: Milošević died during the trial, but he was still found to have been a part of a joint criminal enterprise in the verdicts against
Milan Martić and
Milan Babić, the latter of whom publicly admitted his own (and Milošević's) guilt. According to the ICTY prosecutor's indictment, Milutinović et al., Nikola Šainović, Nebojša Pavković, and Sreten Lukić, along with others, participated in a joint criminal enterprise to modify the ethnic balance in Kosovo in order to ensure continued control by the FRY and Serbian authorities over the province. On 26 February 2009, the court returned the following verdicts: • Nikola Šainović, "had substantial de facto powers over both the MUP and the VJ operating in Kosovo, and that he was the political co-ordinator of these forces. It is convinced that he made a significant contribution to the joint criminal enterprise and that, indeed, he was one of the most crucial members of that common enterprise. He was found guilty "of counts 1 to 5 of the Indictment, by commission as a member of a joint pursuant to Article 7(1) of the Statute". In May 2013,
Jadranko Prlić and others were found guilty for taking part in the joint criminal enterprise with Tudjman for crimes committed in the
Croatian Republic of Herzeg-Bosnia against Muslims. However, on 19 July 2016, the Appeals Chamber concluded that the "Trial Chamber made no explicit findings concerning [Tuđman's] participation in the joint criminal enterprise and did not find [him] guilty of any crimes." In November 2017, the ICTY reaffirmed the first-instance verdict that Tudjman, as well as some other senior Croatian officials, had participated in a joint criminal enterprise with the defendants with the aim of persecuting Bosniaks. ==Rwandan genocide trials==
