Although the Khmer Rouge killed an estimated 1.7 million Cambodian citizens from 1975 and 1979, only now does it appear likely that the perpetrators of these crimes might be brought to justice. Since 1997, the Cambodian government and the United Nations have been engaged in often-heated negotiations about the creation of a tribunal to try former Khmer Rouge leaders. After much work, the two groups seem to have settled on the creation of a mixed tribunal, made up of a majority of Cambodian judges and a minority of foreign ones, to try the former Khmer Rouge leaders for, among other things, genocide, crimes against humanity, and grave breaches of the 1949 Geneva Conventions. The tribunal, which would sit in Cambodia, would operate within Cambodia's existing court structure and would require a supermajority of judges to approve any given ruling; this means at least one foreigner would have to vote with the Cambodians. The U.N. General Assembly and the Cambodian National Assembly must still vote to approve the draft agreement creating the court.
