NCLA Challenges Ninth Circuit Ruling on Covid Vaccine Mandates, Seeks Supreme Court Review
Event summary
- NCLA filed an amicus brief on January 29, 2026, urging the Supreme Court to review Health Freedom Defense Fund v. Carvalho, arguing the Ninth Circuit misapplied Jacobson v. Massachusetts precedent.
- The case challenges the Los Angeles Unified School District’s Covid-19 vaccine mandate, citing evidence that the vaccines do not prevent transmission.
- NCLA claims lower courts have misinterpreted Jacobson to justify vaccine mandates without sufficient public health rationale.
- The brief argues the Ninth Circuit failed to balance individual liberty interests against government mandates.
The big picture

NCLA’s challenge could reshape the legal landscape for vaccine mandates, particularly in education and healthcare sectors. The outcome may also influence how governments balance public safety with constitutional rights in future health crises.
