4/8 "fuller's eight principles"

first principle

generality: rules must be general, not ad-hoc commands for particular individuals

second principle

promulgation/publicitiy: rules must be public announced so citizens know them

third principle

non-retroactivity (no ex post facto): rules can’t be retroactive (no punishment if no law created when act was committed

fourth principle

clarity: must be understandable, not hopelessly vague (ex: doctrine for no vagueness)

fifth principle

non contradiction (catch-22): fighter pilots, can’t contradict one another (supremacy clause)

sixth principle

the possibility of compliance: can’t demand the impossible

seventh principle

contancy/stability: can’t change so frequently that citizens can’t

eighth principle

congruence: official action must match the declared rules (no widespread official disregard)
