In Re Meta Pixel Healthcare Litigation, Judge Orrick denied Meta’s motion to require Doe plaintiffs to use their identities, allowing anonymity.
The ruling allows the Doe plaintiffs to continue using pseudonyms for now and limits Meta’s effort to require them to use their real names. It also recognizes the public’s interest in understanding the case without publicly linking the plaintiffs’ names to their medical information.
What happened
In Re Meta Pixel Healthcare Litigation concerns Meta Platforms, Inc.’s request that the Doe plaintiffs proceed under their real names. The plaintiffs’ claims involve alleged improper capture or use of private health care information.
Meta argued that the case was not unusual enough to justify anonymity. The court found that revealing the plaintiffs’ names while publicly discussing their sensitive medical information could cause greater privacy harm and would not benefit the public’s understanding of the case.
Judge Orrick denied Meta’s motion without prejudice, meaning the balance could change if the case reaches trial and the Doe plaintiffs testify. He also vacated the scheduled hearing.

Background
Meta Platforms, Inc. moved to compel the Doe plaintiffs to proceed using their identities. The court resolved the motion on the papers and vacated the March 26, 2025 hearing.
Federal Rule of Civil Procedure 10 generally requires a complaint to name all parties, and courts presume that parties will use their real names. The Ninth Circuit permits pseudonyms in unusual cases when a plaintiff’s need for anonymity outweighs prejudice to the opposing party and the public’s interest in knowing the plaintiff’s identity.
The Parties’ Positions
Meta argued that this case was not rare or exceptional enough to justify anonymity. Meta relied in part on an earlier decision in which Judge Orrick denied a request to proceed anonymously in a dispute involving the denial of disability benefits.
The Doe plaintiffs’ case is different because it concerns whether Meta improperly obtained or used their private health care information. The specific information allegedly captured or used by Meta was protected by a protective order and redacted from the operative complaint, but the court said that information would be central when the merits of the claims are litigated.
Court’s Analysis
The court concluded that requiring the plaintiffs to use their real names while publicly discussing their sensitive medical information could create an additional and greater privacy intrusion. The court said it was unnecessary at this stage to publicly connect that information to individual plaintiffs.
The court found no prejudice to Meta because amendments to the protective order allowed Meta to use the plaintiffs’ identities for third-party discovery and with in-house counsel. The public interest also favored anonymity: publicly linking the plaintiffs’ names to the information they seek to protect could discourage people from bringing privacy cases, while the plaintiffs’ names were not necessary for the public to understand the case.
Disposition
Judge William H. Orrick denied Meta’s motion without prejudice. The court stated that the balance of interests might change if the case proceeds to trial and the Doe plaintiffs testify. Meta’s motion was therefore denied, and the scheduled hearing was vacated.
