A ruling that defies labels

From George Will:

With the parties warring over the composition of the federal judiciary, and with a Supreme Court vacancy perhaps impending, Americans should use the court's end-of-term decisions as whetstones on which to sharpen their sense of the ambiguities in the categories -- ``liberal,'' ``conservative,'' ``activist,'' ``practitioner of judicial restraint'' -- used when judges are discussed. Consider the case arising from the destruction, by agents of the Drug Enforcement Agency, of Diane Monson's home-grown marijuana plants, a case about which the court's two most conservative justices, Antonin Scalia and Clarence Thomas, disagreed.
