Abstract: For almost a decade, activists have asserted that, through the mechanism of the Eighth Amendment's prohibition on "cruel and unusual punishments," international law either forbids or constrains states from exposing the roughest juvenile criminals to the toughest sentences. Relying in part on those arguments, the Supreme Court of the United States has diminished sentencing options, for adult and juvenile offenders alike, at every turn. However, in Miller v. Alabama, foreign and international law are conspicuous only for their absence. This may signal a welcome shift in the Court's jurisprudence. Activists will no doubt continue to cite foreign and international sources in making their cases against domestic sentencing practices, but Miller at least suggests that the Court has grown wary of such arguments.
