Hui v. Castaneda
The Supreme Court ruled that a federal law giving Public Health Service employees immunity from lawsuits means a detainee's family could not sue two PHS doctors personally over the failure to diagnose his cancer in time, even though the claim was based on the Constitution.
The decision means people harmed by medical staff at PHS-run federal facilities, including immigration detention centers, can only sue the government itself for damages, not the individual doctors or officers involved.
“Section 233(a) grants absolute immunity to PHS officers and employees for actions arising out of the performance of medical or related functions within the scope of their employment by barring all actions against them for such conduct.”
The Court's central holding on what the immunity statute covers.
How it got here: A federal trial court and the Ninth Circuit both let the constitutional lawsuit against the individual doctors proceed; the doctors asked the Supreme Court to review that ruling.
The Case in Depth
What happened
Francisco Castaneda, held in immigration detention, repeatedly asked for a biopsy of a worsening lesion on his penis. Despite a PHS physician's assistant and three outside specialists recommending a biopsy, the PHS doctor and health administrator overseeing his care refused, calling it elective. After his release, tests showed metastatic cancer; he had his penis amputated and later died. His family sued the doctors under the Constitution and sued the government for negligence.
The question before the Court
Can a federal detainee sue individual Public Health Service doctors directly for constitutional violations, or does a federal malpractice law make suing the government the only option?
Why it matters
Immigrants and others held in federal detention who receive negligent or unconstitutional medical care from Public Health Service staff can seek money only from the government under the Federal Tort Claims Act, not from the doctors or officers personally. That limits the punishment and deterrent effect individual lawsuits might otherwise have on PHS medical staff.
What changes now
The case goes back to the lower courts, but the constitutional claims against the individual doctors are now barred. The family's separate negligence claim against the United States under the Federal Tort Claims Act can still proceed, and the government had already admitted liability on that claim while the appeal was pending. This is a final ruling on the immunity question, not a temporary order.
What this does not decide
The Court did not decide whether a constitutional damages remedy would otherwise be available against Public Health Service staff, or address immunity for federal employees outside that agency; it only interpreted the specific text of §233(a) as written.
How the Court got there
The legal reasoning, step by step
- The Court focused entirely on the wording of 42 U.S.C. §233(a), a law making a lawsuit against the United States under the Federal Tort Claims Act the 'exclusive' remedy for injuries caused by Public Health Service staff performing medical duties within their jobs.
- Because the statute's words 'exclusive' and 'any other civil action' are extremely broad, the Court read them to block any personal lawsuit against PHS staff for such conduct, including a constitutional damages suit under Bivens v. Six Unknown Named Agents (a 1971 decision letting people sue federal officers directly for violating their constitutional rights).
- The Court rejected the argument that this reading couldn't be right because the immunity law was written before Bivens existed, reasoning that broad language like 'any other civil action' naturally covers legal claims that didn't yet exist when Congress wrote it.
- The Court found support in a later law, the Westfall Act, which gave similar blanket immunity to other federal employees but explicitly carved out an exception allowing constitutional claims to proceed — showing that when Congress wants to preserve Bivens suits, it says so, and its silence in §233(a) meant no such exception existed there.
- The Court distinguished an earlier case, Carlson v. Green, which addressed a different question (whether a constitutional damages remedy exists at all) rather than whether the individual defendants were personally immune from suit, so it did not control here.
- The Court also rejected the family's arguments that cross-references within the statute or other subsections of §233 secretly preserved a right to sue PHS staff individually, concluding none of those provisions altered the plain immunity granted by §233(a).
