The court's decision in We The Patriots USA v. Ventura Unified School District took the form of an unsigned order.

No justices dissented. The court did not explain its ruling.

The applicant, We The Patriots, is a nonprofit organization headquartered in Caldwell, Idaho.

California's position is that its vaccination mandate keeps children healthy and prevents the spread of dangerous illnesses.

The group filed an emergency application last month with the Supreme Court on behalf of a woman identified as Jane Doe, who is seeking an exemption for her son from the vaccination mandate based on his personal beliefs.

The school district initially granted the son an exemption based on his personal beliefs, but later revoked it. The school district has barred the son from attending school for the time being. His last full day of school attendance was in December 2024.

Doe applied for the exemption based on her understanding that the vaccines required by state law are "researched, developed, tested, and/or produced using cell lines artificially developed from aborted fetuses and contain products that could result in harm to a human recipient," according to the application.

The Constitution's First Amendment does not allow "California to exile children from public school because their parents seek to raise them in accordance with their religious beliefs," the application states, citing the Supreme Court's June ruling in Mahmoud v. Taylor.

In that case, the high court ruled for parents in Maryland who, for religious reasons, wanted to opt their young children out of school storybooks that promote LGBT lifestyles.

"That principle protects parents' right to opt their children out of LGBTQ+ school curricula. It also protects parents' right to opt their children out of an act that would render them complicit in abortion," the application reads.
