Does the European Union have a constitution?
Unlike most of the constitutions of its Member States, the European Union constitution is not laid down in a comprehensive constitutional document, but arises from the totality of rules and fundamental values by which those in authority perceive themselves to be bound. These rules are to be found partly in the founding treaties or in the legal instruments produced by the European Union Institutions, but they also rest partly on custom.
