Then UN Secretary General Kofi Annan initiated an examination to prosecute the leaders of the Khmer Rouge, and in 1999, a bill was introduced in Cambodia to establish a mixed tribunal system there. The Khmer Rouge Tribunal commingles domestic law with international customs and treaties. For example, the definition of genocide has been altered according to the Khmer Rouge Statute, and does not correlate to the Genocide Convention per se. The Tribunal also prohibits foreigners from addressing the court, and only advises international criminal standards if there is a gap in existing Cambodian law.
There have been many obstacles to this tribunal and its fate hangs in the balance. There have been contentions from the Cambodians regarding an understanding of the intent of the Tribunal system, as well as the scope of indictments and the use of foreign counsel. The Cambodians are accused of attempting to limit the scope of the investigation and retain complete autonomy over the system. There have also been allegations questioning the independence and aptitude of Cambodian legal professionals. According to an article by The Guardian, an investigative judge involved with the process has stated that "if new rules are not adopted we will not go forward because it would be useless. Then we would have to examine the possibility of the international judges asking the UN to withdraw the whole process. It's now or never". Thirty years after the atrocities, it appears that justice is on the verge of abandonment.
The mixed tribunal system raises many questions. According to the rules of the International Criminal Court, prosecution cannot proceed without invitation, and invokes a "principle of complimentarity", which states that the ICC compliments a national system and does not replace that system. However, the ICC only holds jurisdiction over cases occurring after its establishment. Furthermore, mixed tribunals are not Security Council derived, but are the results of negotiations between states and the UN. While this system leaves the autonomous entity of the nation state in tact and coordinates with international standards, the logistics may prove overly burdensome, as in the case of the Khmer Rouge.
