By resolution 52/135 the General Assembly requested me to examine the request of the Cambodian authorities for assistance in responding to past serious violations of Cambodian and international law, and those committed by the Khmer Rouge, in particular, and to that end to examine the possibility of appointing a Group of Experts. I accordingly appointed a three-member Group of Experts to evaluate the existing evidence with a view to determining the nature of the crimes committed by Khmer Rouge leaders in the years 1975–1979; to assess the feasibility of their apprehension; and to explore legal options for bringing them to justice before an international or national jurisdiction.
