imperative law

A rule in the form of a command; a rule of action imposed on people by some authority that enforces obedience. "Strictly speaking, it is not possible to say that imperative law is a command in the ordinary sense of the word. A 'command' in the ordinary meaning of the word is an expression of a wish by a person or body as to the conduct of another person, communicated to that other person. But (1) in the case of the law there is no determinate person who as a matter of psychological fact commands all the law. We are all born into a community in which law already exists, and at no time in our lives do any of us command the whole law. The most that we do is to play our part in enforcing or altering particular portions of it. (2) Ignorance of the law is no excuse; thus a rule of law is binding even though not communicated to the subject of the law." John Salmond, Jurisprudence 21 n.(c) (Glanville L. Williams ed., 10th ed. 1947).
