Farrington v. Tokushige, 273 U.S. 284 (1927), was a case in which the Supreme Court of the United States unanimously struck down the Territory of Hawaii's law, making it illegal for schools to teach foreign languages without a permit, as it violated the due process clause of the Fifth Amendment. Violation of the due process clause under the 14th Amendment was not considered as Hawaii was a territory of the United States at the time.

Decision

The Court unanimously affirmed the lower court's decision: The Court stated that "owners, parents and children" are guaranteed rights by the due process clause of the Fifth Amendment with reference to Meyer v. Nebraska, Bartels v. Iowa, and Pierce v. Society of Sisters.
