What should originalists do about precedent? If they respect it, then the original meaning will be lost as a result of erroneous or non-originalist decisions that must be obeyed. if they disregard it, then Supreme Court doctrine is always up for grabs, subject to the latest historical scholarship or good-faith judicial disagreement (as illustrated by the competing Heller opinions). One can imagine intermediate approaches: for example, defer only to good originalist precedents, or defer only when a precedent has become really really entrenched. But while such approaches may delay the eventual disappearance of original meaning behind the encrustation of subsequent opinions, they cannot stop it, sooner or later. Our readings–Lawson, McGinnis & Rappaport, Nelson–provide no way out that I can see. (Lawson dismisses the problem, while the others propose intermediate approaches.) Originalism has an expiration date.
Another issue is raised by McDonald–the gun control case. In Heller, Scalia disregards precedent in order to implement what he thinks was the original understanding of the Second Amendment. In McDonald, he writes a concurrence that cheerfully combines Heller with the anti-originalist incorporation decisions. Why doesn’t he feel constrained to revisit those decisions? Instead, he joins a holding that generates constitutional doctrine that in practical terms is more remote from the original understanding (gun rights that constrain the states) than he would have if he had gone the other way in Heller (no gun rights at all), given the greater importance for policing of the state governments both at the founding and today. This is akin to the second-best problem in economics: partial originalism–originalism-and-precedent–may lead to outcomes that are less respectful to original understandings than non-originalist methodologies would.
