Asakura v. City of Seattle, 265 U.S. 332 (1924) (U.S. Supreme Court)
Asakura v. City of Seattle is a foundational case at the intersection of constitutional supremacy, treaty law, and local police powers.
Does a municipal ordinance restricting pawnbroker licenses to U.S. citizens conflict with and therefore become invalid under the Supremacy Clause in light of the 1911 U.S.-Japan Treaty guaranteeing Japanese subjects the liberty to carry on trade on the same terms as U.S. citizens?
Under the Supremacy Clause, treaties made under the authority of the United States are the supreme law of the land and supersede conflicting state and local enactments. Self-executing treaty provisions that secure rights to nationals of a treaty partner are judicially enforceable by those individuals. While states and municipalities may exercise their police powers to regulate for public safety, such regulations must apply evenhandedly and cannot discriminate against treaty-protected foreign nationals in a manner that conflicts with treaty-guaranteed equality in carrying on trade.
Yes. The Seattle ordinance's citizenship requirement for pawnbroker licenses conflicts with the 1911 U.S.-Japan Treaty and is therefore invalid under the Supremacy Clause. The treaty's guarantee that Japanese subjects may carry on trade upon the same terms as U.S. citizens encompasses the business of pawnbroking, and the ordinance's discriminatory restriction cannot be justified as a permissible police regulation.
Asakura is a leading example of treaty preemption. It confirms that self-executing treaties confer judicially enforceable rights on individuals and that local laws yielding unequal treatment to treaty-protected foreign nationals are invalid. The case also illustrates broad, functional interpretation of treaty terms ("trade") and cabins the police-power exception to nondiscriminatory, generally applicable regulations. For law students, it is essential for understanding the Supremacy Clause's operation with international agreements, the doctrine of self-executing treaties, and the limits of state and municipal authority when international commitments are at stake.
