Takeaway
In short, this case establishes that equal protection forbids not only openly discriminatory laws, but also facially neutral laws enforced in a deliberately unequal way against a racial or national group.
San Francisco required operators of laundries in wooden buildings to obtain the Board of Supervisors’ consent. The ordinance supplied no standards governing that consent. Yick Wo and other Chinese laundry operators had complied with the safety and health requirements applied by city officials, but the Board denied their applications. At the same time, the Board permitted approximately eighty non-Chinese operators to continue the same business in comparable wooden buildings, while denying permission to roughly two hundred Chinese applicants.
Yick Wo was convicted and imprisoned for operating his laundry without the required consent. The Supreme Court of California upheld the ordinance and denied relief, treating the Board’s authority as an ordinary regulatory discretion aimed at fire prevention. In a related proceeding, Wo Lee was denied habeas relief by the federal Circuit Court. The Supreme Court reviewed both judgments to decide whether the ordinances’ enforcement violated federal constitutional rights.
Issue #1
Whether the Court could reconsider the meaning of the San Francisco ordinances while reviewing a state-court judgment limited to federal questions.
Holding
Yes. Although the Court would not review whether the imprisonment violated California law alone, it could independently construe the ordinances insofar as their meaning determined whether their enforcement violated the Constitution or federal law.
Reasoning
The Court’s jurisdiction in Yick Wo’s writ of error extended only to a claimed denial of rights under the Constitution, laws, or treaties of the United States. It therefore accepted the California court’s resolution of purely state-law questions and did not decide whether the imprisonment was independently unlawful under California law.
But the federal constitutional question required the Court to determine what power the ordinances actually gave the Board of Supervisors. The Court rejected the California Supreme Court’s view that the ordinances authorized an ordinary, safety-based licensing discretion. Instead, the ordinances conferred a naked power to approve or deny permission as to particular persons and places without standards, reasons, or legal accountability.
Issue #2
Whether Chinese residents and subjects of China were protected by the Equal Protection Clause.
Holding
Yes. The Fourteenth Amendment protects every person within a state’s jurisdiction, including resident aliens regardless of race, color, or nationality.
Reasoning
The Equal Protection Clause does not use the narrower word “citizen.” Its protections apply to any “person” within a state’s territorial jurisdiction, so Yick Wo and the other Chinese laundry operators could invoke the Clause on the same terms as citizens.
The Court also noted the treaty commitment to protect Chinese residents and the federal civil-rights statute securing to all persons the same rights and legal protections enjoyed by white citizens. The case therefore concerned a constitutional guarantee shared by citizens and aliens alike.
Issue #3
Whether a facially neutral licensing ordinance violates equal protection when officials administer it to exclude Chinese laundry operators while allowing similarly situated non-Chinese operators to continue operating.
Holding
Yes. A law that appears neutral may violate the Equal Protection Clause when public officials administer it with an unequal and discriminatory hand.
Reasoning
Unlike the earlier San Francisco ordinance upheld in Barbier v. Connolly and Soon Hing v. Crowley, this ordinance did not establish uniform operational rules that every laundry could satisfy. It left the livelihoods of laundry operators in wooden buildings dependent on the unbounded will of the Board of Supervisors rather than on objective, safety-related criteria.
The evidence showed actual discriminatory administration, not merely a theoretical risk of abuse. The petitioners and roughly two hundred other Chinese applicants were denied consent despite satisfying all requirements thought necessary to protect health and property, while eighty non-Chinese operators were allowed to conduct the same business under similar conditions.
No legitimate explanation for the disparity appeared in the record. The only reasonable inference was hostility toward the Chinese applicants’ race and nationality. That discrimination was not justified in law, and the city officials’ conduct was attributable to the State for purposes of the Fourteenth Amendment.
The Court announced the enduring principle that even a law fair on its face denies equal protection when public authorities apply it with “an evil eye and an unequal hand,” producing unjustified discrimination among similarly situated persons. Because the petitioners’ convictions rested on that unconstitutional administration, their imprisonment was illegal.
