As part of the continuing consultation process over Cambodia’s proposed Law on Associations and Non-Governmental Organizations (NGO law) CLD and Lawyers Rights Watch Canada (LRWC) have drafted an open letter to senior officials in the Cambodian government. CLD and LRWC note that this newest version of the law, the fourth such draft, includes some improvements. However, the law as currently proposed still violates the fundamental right of freedom of association, and contains problematic provisions, particularly surrounding registration requirements. This letter, like its predecessors, offers substantive critiques of the proposed law. We hope its recipients in the Cambodian government will take heed of these problems before the proposal is passed into law.
