The Sixth Association of Southeast Asian Nations (ASEAN) Chief Justices’ Roundtable on Environment, cohosted by the Asian Development Bank, served as a forum to strengthen ASEAN judges’ knowledge and expertise in environmental and climate change law. The Sixth Roundtable, held in the Philippines on 10–13 November 2016, enabled ASEAN chief justices and their nominees to review prior roundtable agreements and report progress in implementing the Jakarta Common Vision, the Hanoi Action Plan, and the Angkor Statement. The annual roundtable conferences aimed to support ASEAN judges in strengthening their capacity to interpret, apply, and enforce environmental treaties, laws, and regulations based on the rule of law, thereby enabling effective environmental adjudication.
