Fifth Circuit Revives Privacy Class Action Over Meta Pixel Use
The Fifth Circuit revived a class action suit over Meta Pixel's unauthorized health data sharing.
Why it matters: Law firms and legal tech managers face growing litigation risks over website data practices, especially involving sensitive health information. This ruling signals intensified scrutiny on how websites collect and share user data.
- On October 23, 2026, the Fifth Circuit reversed dismissal of a class action against Eyemart Express over Meta Pixel use.
- Five plaintiffs alleged their health-related website activity was shared without consent.
- Court found plaintiffs had standing and that their data likely qualifies as individually identifiable health information (IIHI).
- The case was sent back to the district court for further proceedings, expanding litigation risk for health-related websites.
On October 23, 2026, the U.S. Court of Appeals for the Fifth Circuit revived a significant class action lawsuit involving Meta Pixel, a popular tracking tool used by websites to monitor user actions and share data with Meta Platforms.
The plaintiffs, including five Facebook users, alleged that Eyemart Express, LLC improperly shared their private health-related website activity with Meta through the Pixel without their knowledge or explicit consent. This activity included browsing, purchasing, and appointment scheduling tied to health products and services.
The Fifth Circuit held that the plaintiffs had Article III standing to sue and found that their website activity plausibly constituted individually identifiable health information (IIHI). This recognition as IIHI is critical, subjecting such data collection practices to stricter legal protections.
The court overturned the lower court’s dismissal and remanded the case for further proceedings, underscoring the need for websites handling sensitive health data to secure clear user consent before sharing data with third parties.
Kristin Bryan, an attorney at Squire Patton Boggs, noted, “The Fifth Circuit's decision underscores the importance of obtaining explicit consent before sharing health-related information with third parties.”
This decision may reshape litigation dynamics related to tracking technologies on health-related websites, as companies face increased risks of class action suits for privacy violations.
Website operators and legal professionals should closely monitor this case’s progression to understand evolving compliance requirements and safeguard against potential liabilities.
By the numbers:
- October 23, 2026 — Date of the Fifth Circuit decision
- 5 — Number of Facebook users plaintiffs in the case
- 1 — Circuit court ruling reversing dismissal, expanding litigation risk
Yes, but: The record does not reveal Eyemart Express's response or their potential defenses in the case, which will be critical in later proceedings.
What's next: The case has been remanded to the district court for further proceedings, with potential for significant rulings on tracking technology legal standards.
