[ David Sloss, Professor of Law and Director of the Center for Global Law and Policy, Santa Clara University School of Law, describes his recently published article,
Executing Foster v. Neilson: The Two-Step Approach to Analyzing Self-Executing Treaties. This article is part of the
Third Harvard International Law Journal/Opinio Juris Symposium.]
The Supreme Court’s 2008 decision in
Medellin v. Texas unleashed a flood of new scholarship on the doctrine of self-executing treaties. Unfortunately, the entire debate has been founded on two erroneous assumptions. First, courts and commentators have assumed that self-execution is a treaty interpretation question. Second, they have assumed that the modern doctrine of self-execution is essentially the same as the doctrine articulated by Chief Justice Marshall in his seminal opinion in
Foster v. Neilson. The consensus view is wrong on both counts.
Properly framed, the self-execution inquiry comprises two distinct questions. First, what does the treaty obligate the United States to do? This is a question of international law governed by treaty interpretation principles. Second, which government actors within the United States are responsible for domestic treaty implementation? This is a question of domestic law, not international law: treaties almost never answer this question. Even so, courts and commentators routinely analyze domestic implementation issues by examining treaty text and ancillary documents to ascertain the ostensible intent of the treaty makers. In the vast majority of cases, there is nothing in the treaty text, negotiating history, or ratification record that specifies which domestic legal actors have the power or duty to implement the treaty. Undaunted by the lack of relevant information, courts invent a fictitious intent of the treaty makers. Thus, the “intent-based” doctrine of self-execution, commonly called the “
Foster doctrine,” promotes the arbitrary exercise of judicial power by encouraging courts to decide cases on the basis of a fictitious intent that the courts themselves create.
