In 1886, the United States Supreme Court ruled in Yick Wo v. Hopkins that a San Francisco laundry ordinance was unconstitutionally applied. The decision established that the Fourteenth Amendment protects all persons, regardless of citizenship, from discriminatory enforcement of seemingly neutral laws.
TLDR: The 1886 Supreme Court case Yick Wo v. Hopkins struck down a San Francisco ordinance used to target Chinese laundry owners. The unanimous ruling established that the Fourteenth Amendment’s Equal Protection Clause applies to non-citizens and prohibits the discriminatory administration of laws that appear neutral on their face.
In the late 19th century, San Francisco was a city defined by rapid growth and simmering racial tensions. By 1880, the city’s laundry industry had become a focal point for anti-Chinese sentiment. To address perceived fire hazards, the San Francisco Board of Supervisors passed an ordinance requiring any laundry located in a wooden building to obtain a special permit. On its surface, the law seemed like a reasonable exercise of municipal police power designed to protect a densely packed urban environment from the constant threat of fire. However, the reality of its enforcement told a much different story.
At the time, approximately 320 laundries operated within the city limits. Of these, roughly 240 were owned and operated by Chinese immigrants, and nearly all of them were housed in wooden structures. When the permit process began, the Board of Supervisors denied the applications of every single Chinese laundry owner who applied—over 200 individuals. In stark contrast, the Board granted permits to 80 non-Chinese laundry owners, denying only one. This blatant disparity revealed that the ordinance was not being used for public safety, but as a tool of economic and racial exclusion.
Among those targeted was Lee Yick, who operated a business under the name Yick Wo. He had run his laundry in the same wooden building for 22 years and had consistently passed inspections by fire wardens and health officers. Despite his impeccable record, his permit application was summarily rejected. Refusing to accept the arbitrary destruction of his livelihood, Lee Yick continued to operate his business. He was subsequently arrested and fined ten dollars. When he refused to pay, he was imprisoned by Sheriff Hopkins.
With the support of the Chinese Laundry Guild, Lee Yick sued for a writ of habeas corpus, eventually bringing his case before the United States Supreme Court. The city argued that the ordinance was a valid safety measure and that the Board of Supervisors held absolute discretion over permit approvals. They contended that as a non-citizen, Lee Yick did not enjoy the same constitutional protections as Americans.
In 1886, the Supreme Court issued a unanimous and transformative ruling. Justice Stanley Matthews, writing for the Court, rejected the city’s arguments. The Court held that the Fourteenth Amendment’s Equal Protection Clause protects all “persons” within the jurisdiction of the United States, regardless of their race, nationality, or citizenship status. This was a landmark declaration that extended the shield of the Constitution to immigrants who were otherwise marginalized by law and society.
The Court’s most enduring contribution was its analysis of how the law was applied. Matthews famously wrote that even if a law is fair and impartial on its face, it is unconstitutional if it is “applied and administered by public authority with an evil eye and an unequal hand, so as practically to make unjust and illegal discriminations between persons in similar circumstances.” The Court found that the “grossly unequal” administration of the permit system was proof of a constitutional violation.
The decision in Yick Wo v. Hopkins invalidated the ordinance and secured Lee Yick’s release. More importantly, it established a vital legal precedent: the government cannot hide behind neutral language to practice systemic discrimination. By allowing statistical evidence of disparate impact to prove a violation of rights, the Court provided a powerful tool for future civil rights litigation. For over a century, Yick Wo has served as a cornerstone for challenging discriminatory policing, jury selection, and voting restrictions, ensuring that the promise of equal justice remains more than just words on a page.
