Abstract: | In the 1980s, the U. S. Supreme Court was expected to becomemore solicitous of "states' rights" and to reconsider doctrinesof federal preemption of state and local laws. Those expectationswere built on the Court's ruling in National League of Citiesv. Usery and reinforced by the Reagan administration's rhetoricand Court appointments. The record ofthe Rehnquist Court, however,demonstrates that it has backed away from vigorously enforcingthe Tenth Amendment and has erected only minor constitutionalbarriers, as in New York v. United States, to the Congress'power over the states. Moreover, the Court has not retreatedfrom finding implied statutory preemptions or from imposingits own dormant-commerce clause power on the states. The articleconcludes by considering a number of explanations for the Court'srecord and rulings on federal preemption. |
