1 I should make clear that I am referring to a system of binding legal norms. Perhaps we could talk about a parallel system of nonbinding (recommendatory) norms, which are legal in some sense (especially in the sense of being created by legal procedures), and also about a combined system of binding and nonbinding norms, which would yield different types of results, according to the nature of the intervening norms, etc. These complications need not be pursued here.
