The California Supreme Court's decision in J.M. v. Illuminate Education has fundamentally altered the requirements for data breach claims under the state's Confidentiality of Medical Information Act. This ruling creates new exposure for companies by eliminating the need to prove unauthorized viewing of medical data, while simultaneously clarifying which entities fall under the statute's jurisdiction.

The California Supreme Court's decision in J.M. v. Illuminate Education significantly reshapes the landscape for claims under California's Confidentiality of Medical Information Act (CMIA). The court lowered the bar for certain data breach claims by holding that plaintiffs need not show their medical information was actually viewed by an unauthorized person. At the same time, it reinforced important limits on which companies qualify as health care providers subject to the statute.
