When may we call a policy the progeny of an earlier, discriminatory policy, especially if the policies diverge in design and designer? Does such a relationship condemn the later policy for all times and purposes, or can a later decisionmaker escape the past? It is an old problem, but its resolution hardly seems impending. Just recently, Supreme Court cases have confronted this fact pattern across subject matters as diverse as entry restrictions, nonunanimous juries, and redistricting, among others. Majority opinions seem unsure whether or why “discriminatory predecessors” matter, and individual Justices who agree that they do squabble over methodology.
