Yick Wo v. Hopkins
The Court struck down San Francisco's enforcement of laundry permit ordinances after finding that city supervisors approved permits for eighty non-Chinese applicants while denying them to about two hundred Chinese applicants, including the two petitioners, under identical circumstances.
Even though the ordinances themselves did not mention race, the Court ruled that applying a neutral-looking law with a deliberately unequal hand against one group violates the Fourteenth Amendment's guarantee of equal protection, a guarantee that covers every person within the country's jurisdiction, not just citizens.
How it got here: California's Supreme Court upheld Yick Wo's conviction and a federal circuit court denied Wo Lee's habeas petition; both men brought their cases to the U.S. Supreme Court.
The Case in Depth
What happened
Yick Wo and Wo Lee, both Chinese immigrants, ran wooden-building laundries in San Francisco, a common and useful trade among Chinese residents. City ordinances required anyone operating a laundry in a wooden building to get the consent of the Board of Supervisors. The supervisors refused consent to Yick Wo, Wo Lee, and roughly two hundred other Chinese applicants, while approving about eighty non-Chinese applicants running laundries under essentially identical conditions.
The question before the Court
Could San Francisco deny laundry permits almost entirely to Chinese applicants while granting them to nearly everyone else under the same rules?
Why it matters
The ruling meant local governments could not hide discriminatory treatment behind laws that appear fair on their face, protecting immigrants and other vulnerable groups from officials who apply supposedly neutral licensing rules unevenly. It also confirmed that constitutional equal-protection guarantees extend to noncitizens, not just American citizens, shaping how courts scrutinize discriminatory enforcement of ordinary regulations ever since.
What changes now
The Court reversed the California Supreme Court's judgment against Yick Wo and the federal circuit court's ruling against Wo Lee, ordering both men discharged from custody immediately. This was a final decision on the merits, not a temporary order, and it established a lasting rule that neutral laws administered with intentional, unequal severity against a particular group violate the Constitution regardless of the law's wording.
What this does not decide
The Court did not rule that cities can never require permits or licenses for businesses like laundries, nor that officials can never be given any discretion over such approvals. The decision addressed only the specific pattern shown here: an unguided, arbitrary licensing power applied almost exclusively against one racial group with no legitimate justification offered.
How the Court got there
The legal reasoning, step by step
- The Court first had to determine what the city ordinances actually meant, since that question controlled whether they violated federal constitutional rights. It concluded, contrary to the California Supreme Court, that the ordinances gave the Board of Supervisors a completely unguided, arbitrary power to grant or deny consent — not a reasonable, fact-based discretion tied to safety concerns.
- Because the power was arbitrary rather than guided by standards, the Court distinguished this case from two earlier decisions, Barbier v. Connolly and Soon Hing v. Crowley, which had upheld a straightforward nighttime laundry-hours rule that applied equally to everyone and left no room for one-sided enforcement.
- The Court explained that the Fourteenth Amendment's equal protection guarantee applies to 'any person' within a state's jurisdiction, not only citizens, so Chinese immigrants were entitled to the same protection as anyone else, reinforced by a treaty promising China's subjects the same rights as citizens of the most-favored nation.
- The Court then applied a broader principle: even a law that looks neutral on its face violates equal protection if public officials administer it with such a deliberately unequal hand that it amounts to intentional discrimination against a particular class of people, not merely uneven results from case-by-case judgment.
- Applying that principle to the facts, the Court found the petitioners had met every legitimate safety requirement, yet permits were denied only to Chinese applicants while granted to about eighty others in the same business under like conditions, with no explanation offered besides hostility toward their race and nationality.
- The Court concluded this systematic, unexplained one-sidedness could only be explained by hostility to the petitioners' race and nationality, making the enforcement an illegal discrimination and a denial of equal protection of the laws.
Doctrinal impact
Cases affected by this decision
Distinguishes Barbier v. Connolly (113 U. S. 27)
The Court said this earlier ruling upheld a truly neutral, evenly-applied nighttime laundry rule, unlike the arbitrary ordinance here.
Distinguishes Soon Hing v. Crowley (113 U. S. 703)
The Court distinguished this case because that ordinance applied equally to everyone, unlike the arbitrary power at issue here.
