 The best known are the eight formal principles of Lon Fuller’s “inner morality of law”: (1964; see also the lists in Finnis 1980: 270–1; Rawls 1999: 208–10; and Raz 1979 [1977]: 214–18) generality; publicity; prospectivity; intelligibility; consistency; practicability; stability; and congruence. These principles are formal, because they concern the form of the norms that are applied to our conduct.
