Reimagining Türkiye Halk Bankasi: A Way Forward for Common Law Displacement Doctrine
Evan M. Meisler
In Türkiye Halk Bankasi A.S. v. United States, the Supreme Court reviewed the Second Circuit’s holding that the passage of the Foreign Sovereign Immunities Act (FSIA) abrogated any immunity from prosecution that foreign sovereigns may have previously enjoyed under the federal common law. The Court reversed, holding that the FSIA is inapplicable in the criminal context and, therefore, left the federal common law of sovereign immunity from prosecution undisturbed. The Court’s reasoning, however, did not explicitly draw upon or elucidate the doctrine of federal common law displacement. It is possible that the Court chose not to engage with this doctrine because its underlying case law has thus far failed to supply a clear, consistent, and administrable standard for federal common law displacement. Recent appellate decisions concerning the federal common law of foreign sovereign immunity illustrate the need for doctrinal reform.
This Note advocates the adoption of a different method for analyzing federal common law displacement disputes, drawing upon an analogy to the better defined and familiar doctrine of state law preemption. Specifically, I argue that statutes may either “expressly displace,” “conflict displace,” or “field displace” the federal common law, categories which I define by reference to express, conflict, and field preemption. I contend that this framework, although never formally endorsed in so many words by any federal court, is already immanent in the Supreme Court’s case law and the scholarly literature. Using Türkiye Halk Bankasi as a case study, I illustrate how the Court could have applied this framework to reach the same result while providing courts and litigants with a more structured approach for future federal common law displacement controversies.
