The U.S. Supreme Court has reopened the debate over whether states may eliminate religious exemptions to school vaccine mandates, vacating a lower court ruling that upheld New York’s strict immunization law and ordering a new review under strengthened protections for religious liberty.
In a brief order issued Monday, the Court sent Miller v. McDonald back to the U.S. Court of Appeals for the Second Circuit. The justices directed the lower court to reconsider whether New York’s 2019 repeal of religious exemptions violates the Free Exercise Clause, particularly in light of the Court’s recent decision in Mahmoud v. Taylor.
In Mahmoud, a majority of justices concluded that a Maryland county board of education violated the religious rights of parents by introducing the books into the county’s curriculum and later forbidding parents from removing their children from classrooms when the stories were read. The Supreme Court’s action effectively resets the case, signaling that courts must take a closer look at whether denying all religious exemptions imposes an unjustified burden on faith communities.
The lawsuit was filed by Amish families and other parents who argue that New York’s law forces them to choose between their faith and their children’s education. For more than fifty years, New York has allowed families with sincere religious objections to opt out of school vaccination requirements. Lawmakers eliminated that longstanding protection in 2019, leaving medical exemptions as the only option. Families who cannot comply due to their religious beliefs must either vaccinate their children or withdraw them from school; those who continue to refuse face truancy actions and financial penalties.
The families argue that the state’s mandate operates as a form of government pressure on religious practice. Their attorneys say that the Supreme Court’s intervention confirms that the lower courts did not fully consider the constitutional significance of religious liberty. Kelly Shackelford, president and CEO of First Liberty Institute, which represents the plaintiffs, stated that the order demonstrates the courts must take seriously the burden placed on religious families. He added that the Amish community wants to be allowed to live out its faith as it has for generations, free from state coercion.
The Second Circuit had previously upheld New York’s elimination of religious exemptions, ruling that the state acted within its authority to protect public health. The Supreme Court’s decision to vacate that ruling marks a major procedural shift in the years-long legal fight. Religious-liberty advocates argue that it reflects a growing understanding within the judiciary that parental rights and faith-based objections cannot be dismissed without careful consideration. Supporters of exemptions argue that the government must justify policies that force families to violate their sincerely held beliefs, particularly when less restrictive alternatives have existed for decades.
The ruling also comes as debates over school vaccination policies have intensified nationwide. Education Week reported that the Court’s order requires New York’s law to be re-evaluated under the more protective framework established in Mahmoud, which recognized that schools burden religious exercise when families are required to participate in programs that violate their beliefs. Advocates for exemptions say the Supreme Court’s involvement signals that the time has come to reconsider blanket bans on religious opt-outs and to restore the balance between public health and constitutional freedoms.
“The Amish community in New York wants to be left alone to live out their faith just like they have for 200 years,” Shackelford said in a statement.
“Who is the authority over our children? Their parents or government bureaucrats? Ultimately, this case will affect every American—their religious freedoms and the authority of every parent to raise their children according to their faith.”
