Doctrines governing the structure and limits of government power: how a constitution is read, how the branches of government relate to one another, and how the state's own action is held to legal standards. Belongs here: Administrative Law, Basic Structure Doctrine, Constitutional Interpretation, Due Process, Judicial Review, Proportionality, Rechtsstaat, Rule of Law and Separation of Powers. Does not belong here: a doctrine confined to how criminal charges are brought or tried, grouped under criminal law and procedure instead, even where it also touches constitutional rights, such as Habeas Corpus or the Exclusionary Rule.
