A jealous wife’s attempt to poison a rival gave the Supreme Court a splendid chance to detoxify a pernicious constitutional law doctrine about the scope of the treaty power, but yesterday the Court passed up the chance. [Earlier.] My colleague Ilya Shapiro explains. Chief Justice Roberts, for the majority: “The global need to prevent chemical warfare does not require the federal government to reach into the kitchen cupboard, or to treat a local assault with a chemical irritant as the deployment of a chemical weapon.”
P.S. Congratulations to my colleague Nicholas Quinn Rosenkranz and the Cato Institute amicus program (i.e. Ilya Shapiro) for the way Justice Scalia in his concurrence picks up whole chunks of argumentation from Nick’s 2005 HLR article on the treaty power and Cato’s recent amicus brief based on the same line of argument. Also, for those keeping score, this is another embarrassing 0-9 goose-egg defeat for the Obama administration, which once again took a position totally aggrandizing of federal government power and once again could not win for it the vote of even a single Justice.
