This submission – co-authored by Redress, Asian Human Rights Commission, and the Rehabilitation and Research Centre for Torture Victims – calls on the UN Secretary General’s Panel of Experts to call on the the UN Security Council under Chapter VII of the Charter to establish a Commission of Inquiry to investigate violations of international humanitarian law and human rights law during the final stage of the conflict in Sri Lanka. Should this recommendation not be accepted, we submit that the Panel should recommend the establishment of a fact-finding mission in order to request Sri Lanka itself take appropriate action against the perpetrators.
