Thornton v. Ipsen Biopharmaceuticals, Inc., No. 23-1951 (1st Cir. 2025)
Annotate this Case
Regina M. Thornton was employed by Ipsen Biopharmaceuticals, Inc. as Associate Director - Patient Safety. In September 2021, Ipsen required employees to receive COVID-19 vaccinations. Thornton requested a religious exemption, which Ipsen denied. After she did not comply with the vaccination requirement, Ipsen terminated her employment. Thornton sued Ipsen in the Superior Court of Massachusetts, alleging violations of Title VII, Massachusetts law (Chapter 151B), the Fourteenth Amendment, and the Massachusetts Declaration of Rights (MDR). Ipsen removed the case to the United States District Court for the District of Massachusetts and moved to dismiss all counts. The Magistrate Judge granted Ipsen's motion, dismissing Thornton's complaint. Thornton appealed.
The United States District Court for the District of Massachusetts dismissed Thornton's complaint, finding that she failed to state a plausible claim of religious discrimination under Title VII or Chapter 151B. The court concluded that Thornton did not adequately state her religious beliefs or how they related to vaccines. The court also found that Thornton's federal constitutional claims failed because Ipsen was not a state actor, and her MDR claims failed because the MDR does not provide a private right of action.
The United States Court of Appeals for the First Circuit reviewed the case. The court reversed the Magistrate Judge's dismissal of Thornton's religious discrimination claims under Title VII and Chapter 151B, finding that she had plausibly alleged that her religious beliefs conflicted with the vaccination requirement. However, the court affirmed the dismissal of her federal constitutional claims, as the Fourteenth Amendment does not apply to private actors like Ipsen. The court also affirmed the dismissal of her MDR claims, noting that Thornton had waived any argument that her claim should be reimagined under the Massachusetts Civil Rights Act.
