Diane Marie Amann, U.C. Davis, has a new paper/forthcoming article on SSRN, taking up the use of international law in domestic cases, International Law and Rehnquist-Era Reversals. Here's the abstract:
In the last years of Chief Justice Rehnquist's tenure, the Supreme Court held that due process bars criminal prosecution of same-sex intimacy and that it is cruel and unusual to execute mentally retarded persons or juveniles. Each of the later decisions not only overruled precedents set earlier in Rehnquist's tenure, but also consulted international law as an aid to construing the U.S. Constitution. Analyzing that phenomenon, the article first discusses the underlying cases, then traces the role that international law played in Atkins, Lawrence, and Simmons. It next examines backlash to consultation, and demonstrates that critics tended to overlook the Court's longstanding tradition of consulting external norms. The article gives the interpretive practice qualified approval. Thus it calls upon Justices both to articulate when it is appropriate to look to external sources and to set forth a framework for consultation. At a minimum, foreign jurisprudence ought to shed the light of experience on issues like those in the case before the Court; it must arise out of a legal culture that shares with the United States a commitment to fundamental rights; and the way in which the jurisprudence influenced the Court must be set forth in a reasoned explanation. Whether the Court would pursue such a path remained uncertain, however, as the era of the new Chief Justice began.
