Background

Erin Weiler, a Delta Dental of California plan member, filed a putative class action in San Francisco Superior Court alleging that Delta Dental used hidden tracking technologies on its website to collect and disclose to third parties non-public information about website users without their knowledge or consent. After logging into Delta Dental’s website in June 2024 and authenticating as a plan member, she alleges, she searched for nearby dentists by entering her location and plan type, and Delta Dental allegedly captured her IP address, her status as a Delta Dental plan member, and her search criteria, then transmitted that information to third parties.

Weiler asserts seven claims: negligence; breach of fiduciary duty; breach of confidence; unjust enrichment; California Invasion of Privacy Act § 631(a); California Unfair Competition Law § 17200; and the federal Electronic Communications Privacy Act § 2511. Delta Dental removed the case to the Northern District on March 26, 2025, asserting federal-question jurisdiction based on the ECPA claim. About a week later, Delta Dental moved to dismiss all claims for lack of Article III standing under Rule 12(b)(1) and, alternatively, under Rule 12(b)(6).

The Court’s Holding

Judge Haywood S. Gilliam, Jr. remanded the case to San Francisco Superior Court and denied Delta Dental’s motion to dismiss as moot.

The court joined the growing chorus of federal courts criticizing the “remove and immediately challenge standing” tactic. As Weiler pointed out and the court agreed, removing a case based on a federal claim and then arguing the plaintiff lacks Article III standing on that very claim is a “dubious” litigation strategy that wastes time and judicial resources. The proper outcome when a plaintiff lacks Article III standing for the federal claim that supplied the basis for removal is remand under 28 U.S.C. § 1447(c), not dismissal.

Although the court did not finally decide the standing question, it found enough doubt about Article III standing — particularly under TransUnion v. Ramirez’s requirement of concrete injury — to require remand. The information Weiler alleged Delta Dental shared with third parties (IP address, plan-member status, search criteria) might or might not satisfy TransUnion’s concrete-injury threshold for the federal ECPA claim. State courts, however, are not bound by Article III and can consider the case under California’s broader standing doctrines for the state-law claims, especially the California Invasion of Privacy Act and UCL claims, which were the substantive heart of the complaint.

Because the federal court could not retain jurisdiction over a case where the federal claim was at minimum vulnerable to a standing challenge, and because Delta Dental had effectively conceded as much by moving to dismiss on standing grounds, the entire case was remanded.

Key Takeaways

  • Defendants who remove California Invasion of Privacy Act and UCL website-tracking class actions to federal court based on a federal ECPA claim and then immediately challenge Article III standing risk having the case remanded back to state court.
  • The “remove-and-dismiss” tactic for getting privacy class actions dismissed at the federal door is increasingly disfavored. Northern District judges treat it as wasteful and incompatible with proper § 1447(c) practice.
  • State courts are not bound by Article III and can hear cases that may not meet TransUnion v. Ramirez’s concrete-injury requirement. CIPA and UCL claims based on website tracking are particularly likely to find a more receptive forum in state court.
  • For plaintiffs filing CIPA / website-tracking class actions in California, the state-court forum is generally preferable. Federal forums introduce Article III standing complications that may eliminate weaker injury theories.
  • Defendants seeking to dispose of these cases should choose between vigorous standing defenses (ideally pre-removal in state court) and federal-court litigation on the merits, not both.

Why It Matters

Website tracking class actions under California’s Invasion of Privacy Act and similar statutes have exploded in recent years, targeting major California-based and California-facing companies for their use of pixels, cookies, session-replay tools, and other tracking technologies. Defendants frequently remove these cases under federal wiretap statutes like the ECPA and then move to dismiss for lack of Article III standing, hoping to terminate the case at the federal door.

This decision adds to a growing line of Northern District opinions remanding such cases rather than dismissing them outright when standing is in doubt. The result is that plaintiffs often end up back in state court with their core CIPA and UCL claims intact, while defendants have lost the federal-court forum and incurred remand-related fees risk. For the broader privacy-litigation landscape, the case continues the migration of website-tracking class actions toward California state courts as the natural battleground.
