FORMER Tuol Sleng prison chief Kaing Guek Eav, alias Duch, has enlisted an Israeli lawyer as a consultant as he prepares to appeal his conviction at the Khmer Rouge tribunal, United Nations court spokesman Lars Olsen said yesterday. The former Khmer Rouge jailer dismissed his international lawyer Francois Roux last month and replaced him with Cambodian attorney Kang Ritheary, citing a “loss of confidence” in Roux’s representation. Defendants at the tribunal are typically represented by both Cambodian and international lawyers, though this is not a requirement. Olsen said Kaufman was not expected to be present in Cambodia for appeal hearings.
