On December 19, 2019, the Pre-Trial Chamber (PTC) of the Extraordinary Chambers in the Courts of Cambodia (ECCC) rendered its “Considerations on Appeals Against Closing Orders” in Case 004/2 Involving Ao An. The 266-page ruling exemplified, and brought to a head, the longstanding conflict within the ECCC between the national and international co-prosecutors and between the national and international judges on the parameters of personal jurisdiction and the interpretation of relevant provisions of the ECCC's constitutional documents. The fate of the ECCC now hangs in the balance.
