Doe v. Dynamic Physical Therapy, LLC

Background

A person identified as John Doe sued Dynamic Physical Therapy, LLC and others after care connected to a public-health emergency. Louisiana has a law that grants healthcare providers immunity from civil liability during public-health emergencies. A Louisiana Court of Appeal concluded that this state immunity statute barred the plaintiff’s federal lawsuits, and the state courts declined further relief, so the plaintiff asked the Supreme Court to review whether a state law can prevent federal claims.

Reasoning

The central question was whether a State may use its own law to extinguish federal causes of action. The Court explained that while a State may define liability under its own laws, it cannot confer immunity that defeats federal causes of action. The opinion cited prior decisions and emphasized that judges in state courts are bound to follow federal law under the Constitution’s supremacy rules. The Supreme Court granted review, reversed the Louisiana Court of Appeal’s judgment that had barred the federal claims, and remanded the case so the state courts can consider the federal claims in the first instance consistent with federal law. The Court also noted the plaintiff’s federal claims might still fail on other federal grounds.

Real world impact

The decision means state statutes that try to shield providers during emergencies cannot by themselves prevent federal lawsuits; patients and others may still bring federal claims. Hospitals, clinics, insurers, and state lawmakers who adopt immunity rules will need to account for federal-law limits. The ruling is not a final judgment on the plaintiff’s claims—lower courts must now address the federal issues under the rules the Supreme Court described.
