The Khmer Rouge

tribunal will hold a public hearing on December 5 on the appeal by

co-prosecutors of the case put forward against former S-21 prison head

Kaing Guek Eak, also known as Duch. The hybrid court's co-prosecutors

argued in August that the court order did not represent the full extent

of his alleged crimes. Duch will be the first of five former Khmer

Rouge leaders to go on trial early next year.
