Starting with the proposition that "'Constitutionalism' refers to the position or practice that government be limited by a constitution, usually written," analysts take a variety of positions on what the constitution means. For instance, they describe the document as a document that may specify its relation to statutes, treaties, executive and judicial actions, and the constitutions or laws of regional jurisdictions. This prescriptive use of Constitutionalism is also concerned with the principles of constitutional design, which includes the principle that the field of public action be partitioned between delegated powers to the government and the rights of individuals, each of which is a restriction of the other, and that no powers be delegated that are beyond the competence of government.[29]
