These include minor property cases, such as Dolan v. City of Tigard, in which Stevens, in a dissent, argued for the government’s right to force a store owner to place a public green on her property.
But the case that figures most prominently in Stevens’ legacy is Kelo v. New London. It set a precedent that exposed the dark consequences of liberalism’s sympathy for Big Government.
Stevens’ Kelo opinion leaned on the noble pillar of “deference to legislative judgment,” but that profession of humility is hard to swallow from a man who also spent his career smashing any legislative attempts to protect the unborn. Abortion, of course, is another issue where the voiceless, vulnerable, little guy didn’t find an advocate in Stevens.
