Lawyers for "Brother No 2" Nuon Chea have filed an appeal to the pretrial chamber at the Khmer Rouge tribunal over corruption at the UN-backed court. According to the defence team's legal consultant Andrew Ianuzzi, laywers have requested the appeal be made public. Lawyers requested the chamber help make public a review of kickback allegations made by the UN's internal oversight body. However, it was rejected last month on the basis that such a task was not the responsibility of judges.
