Third Circuit Affirms Dismissal Of CIPA Adtech Class Action Because A Party To A Communication Cannot Eavesdrop On Itself

Duane Morris Takeaways: On November 13, 2025, in Cole, et al. v. Quest Diagnostics, Inc., 2025 U.S. App. LEXIS 29698 (3d Cir. Nov. 13, 2025), the U.S. Court of Appeals for the Third Circuit affirmed a ruling of the U.S. District Court for the District of New Jersey's in dismissing a class action complaint brought by website users against a diagnostic testing company alleging that the company's use of website advertising technology violated the California Invasion of Privacy Act ("CIPA") and California's Confidentiality of Medical Information Act ("CMIA").

The ruling is significant because it confirms two important principles: (1) CIPA's prohibition against eavesdropping does not apply to an online advertising company, like Facebook, when it directly receives information from the users' browser; and (2) the CMIA is not triggered unless plaintiffs plausibly allege the disclosure of substantive medical information.
