Zucht v. King
The Court dismissed a student's challenge to a San Antonio ordinance requiring vaccination certificates for school attendance, holding that the ordinance's basic validity was not a serious enough constitutional question to warrant review, since earlier cases had already settled that cities can require vaccination and delegate broad discretion to health officials.
The Court also found that her separate complaint—that officials applied the ordinance unfairly against her personally—raised a real constitutional issue, but not one that could be brought to the Supreme Court by this kind of appeal, so the whole case was dismissed.
How it got here: Texas trial and appellate courts rejected her claims and the state supreme court refused review; after a defective certiorari petition, she brought this case up on a writ of error.
The Case in Depth
What happened
Rosalyn Zucht, a schoolgirl in San Antonio, was barred from both a public school and a private school because she lacked a vaccination certificate and refused to be vaccinated, as required by city ordinances. She sued local officials, arguing the ordinances violated her right to due process by effectively forcing vaccination and gave health officials unchecked, unguided discretion over enforcement.
The question before the Court
Could a city force a schoolgirl out of school for refusing vaccination without the Supreme Court reviewing whether the vaccination ordinance itself was unconstitutional?
Why it matters
The decision reinforced that local governments can require vaccination for school attendance and can give health boards broad discretion to decide when and how to enforce that requirement, without every such ordinance being open to full Supreme Court review. It also showed that claims about unfair enforcement of a valid law, as opposed to challenges to the law itself, follow a different, narrower path to the Court.
What changes now
The writ of error was dismissed outright, ending this avenue of Supreme Court review. Because the ordinance's validity was not seriously in question, the vaccination requirement and the officials' underlying authority remained intact. Zucht's separate complaint about unfair treatment in how the ordinance was applied to her was left unresolved by this ruling, since that kind of claim could only be pursued, if at all, through a petition for the Court to voluntarily take up the case rather than through the writ of error she had filed.
What this does not decide
The Court did not decide whether San Antonio officials actually treated Rosalyn Zucht unfairly in applying the vaccination ordinance to her. It found that question serious enough to matter, but ruled only that a writ of error was the wrong procedural tool to raise it, leaving that specific dispute unresolved.
How the Court got there
The legal reasoning, step by step
- The Court first asked whether the ordinance's validity presented a genuinely serious constitutional question, since the Court must decline jurisdiction on a writ of error if the constitutional issue isn't substantial, even if it was formally raised below.
- The Court noted that its own prior decisions had already settled that states may require compulsory vaccination as a valid use of their power to protect public health, and that states may hand that power down to cities.
- It further noted precedent establishing that a city may give its health officials broad discretion in deciding when and how to enforce a health ordinance, and that treating different situations differently under such a law does not by itself violate the guarantee that people be treated equally under the law.
- Because these points were already well-settled, the Court concluded the ordinance's basic validity was not a substantial enough question to support the writ of error, distinguishing it from cases where officials were given truly arbitrary, unguided power.
- Turning to the separate claim that officials applied the ordinance unfairly to her specifically, the Court found this did raise a real constitutional question, but concluded that a challenge to how a valid law was applied—rather than to the law itself or the officials' authority—cannot be reviewed through a writ of error, only through a request that the Court choose to hear the case.
