A referendum concerning a country's sovereignty, independence, territorial or diplomatic issues of international law, also known as 'people's vote' (plebiscite), whose source of law lies in international law, is a super-constitutional right that cannot be negated by any domestic law. It requires only agreement with the principles of democracy and approving votes from more than 1/2 of those casting ballots. See the Charter for Permanent Peace for details. §1.5 §1.7
