Three other defence

teams at the Khmer Rouge tribunal have joined lawyers for Nuon Chea in

appealing a decision on the issue of corruption at the UN-backed court.

Lawyers for Ieng Thirith, Ieng Sary and Khieu Samphan have filed

appeals over the court's decision in April not to take investigative

action on an alleged kickback scheme at the court. Though judges

claimed it was not in their jurisdiction to investigate such claims,

lawyers argued Monday that judges have the inherent power to ensure the

integrity of their own proceedings, and wihout such an investigation

their clients' rights to a fair trial would be violated.
