A judicial declaration of constitutional invalidity does not erase a challenged law. Such a law is “dead” in that enforcement efforts will not succeed in court, where judicial precedent binds and dictates the outcome in future litigation. But such a law is “alive” in that it remains on the books and may be enforced by a departmentalist executive acting on an independent constitutional judgment. Judge Gregg Costa has labeled these statutory remainders “zombie laws.” This Article describes several principles that define constitutional litigation, how those principles produce zombie laws, and the scope and nature of zombie laws. It then describes how Congress or state legislatures can eliminate or enable future enforcement of zombie laws by repealing or retaining them, depending on their views of judicial precedent and what they want to see happen with their laws in the future.
