Doe v. SSM Health Care Corporation, No. 23-3138 (8th Cir. 2025)
Annotate this Case
John Doe filed a putative class action against SSM Health Care Corporation in Missouri state court, alleging that SSM shared private health information with third-party marketing services without authorization, violating Missouri law. Doe claimed that SSM's MyChart patient portal transmitted personal health data to third-party websites like Facebook. The lawsuit included nine state law claims, such as violations of the Missouri Wiretap Statute and the Computer Tampering Act.
SSM removed the case to federal court, citing the federal officer removal statute and the Class Action Fairness Act (CAFA). Doe moved to remand the case to state court. The United States District Court for the Eastern District of Missouri rejected SSM's arguments, ruling that SSM was not "acting under" a federal officer and that Doe's proposed class was limited to Missouri citizens, thus lacking the minimal diversity required under CAFA. The district court remanded the case to state court.
The United States Court of Appeals for the Eighth Circuit reviewed the case de novo. The court affirmed the district court's decision, holding that SSM did not meet the criteria for federal officer removal because it was not acting under the direction of a federal officer. The court also held that the proposed class was limited to Missouri citizens, which destroyed the minimal diversity necessary for CAFA jurisdiction. Consequently, the Eighth Circuit affirmed the district court's remand order.
