 So for example, the requirement that laws be general in character, rather than aimed at particular individuals, is purely a matter of form. It is compatible with invidious discrimination so far as its substance is concerned, since even a norm like “A person who is of African descent must sit in the back of any public bus that they ride on” applies, universalizably, to everyone. A formal requirement of generality does not guarantee justice; but that partly reflects the fact that justice and the Rule of Law work as separate criteria for evaluating a political system.
