[T]he courts that held slaves to be non-persons, separate to be equal, and pregnancy to be non sex-related can hardly be deemed either final or infal… - Laurence Tribe

If the legislature would punish, it must enlist... the other branches—the executive to prosecute, the judicial to try and convict.

One cannot speak of "groups" as though society were objectively subdivided... Instead, people draw lines, attribute differences, as a way of ordering social justice—of deciding who may occupy what place, play what role, engage in what activity. Thus, in order to justify the role of chattel that blacks initially played in our society, we may have differentiated that role by describing it in terms of the most obvious distinguishing feature... equating race and role. This equation and thus "group" survived the Civil War and the Thirteenth Amendment... simply by reason of confusion or inertia, but because the role that society allowed remained partially unchanged; thus, the need to justify the role by differentiating it, by seeing not the role but the group—"inferior" blacks capable of nothing better...—persisted.

[T]he question of whethor a particular amendment has... been lawfully ratified... would matter mightily with amendments as the three passed in the wake of the Civil War—the Thirteenth (abolishing slavery), the Fourteenth (defining citizenship and guaranteeing certain basic human rights to all persons in their dealings even with their own states), and the Fifteenth (abolishing racial qualifications for voting)—whose ratification by the legislatures of the former Confederate states was not exactly voluntary. Their acquiescence was secured by force, having been made a condition for their reentry into the Union from which they had attempted to secede.
