Opinion

ERIN WEILER, Case No. 25-cv-02846-HSG

Plaintiff, ORDER REMANDING CASE AND DENYING AS MOOT MOTION TO v. DISMISS

DELTA DENTAL OF CALIFORNIA, Re: Dkt. No. 13 Defendant.

Pending before the Court is Defendant Delta Dental of California’s motion to dismiss. Dkt. No. 13. The Court finds this matter appropriate for disposition without oral argument and the matter is deemed submitted. See Civil L.R. 7-1(b). For the reasons discussed below, the Court REMANDS the action to the Superior Court of California for the County of San Francisco and DENIES AS MOOT the motion to dismiss. Plaintiff Erin Weiler brings this proposed class action against Delta Dental of California (“Delta Dental”) for claims arising out of its use of hidden tracking technologies on its website to collect and disclose to third parties non-public information about the website’s users without the users’ knowledge or consent. See Dkt. No. 1-1 (“Compl.”) ¶¶ 1–10. Delta Dental offers dental health insurance to California residents. Id. ¶ 28. Plaintiff has dental insurance through Delta Dental. Id. ¶ 145. Plaintiff alleges that, in June 2024, she logged into Delta Dental’s website and, after she was authenticated as a Delta Dental plan member, she used the website to search for dentists located near her by inputting her location and plan type. Id. authorized the sharing of her personal information with third parties. Id. ¶¶ 137–40. Delta Dental allegedly used hidden tracking technologies to collect Plaintiff’s IP address, her status as a Delta Dental plan member, and the search criteria she entered into the website. Id. ¶¶ 139–44. Delta Dental then made that information available to third parties without her knowledge or consent. Id. Plaintiff alleges to have suffered injuries as a result of Delta Dental’s conduct in the form of invasion of privacy, violations of the confidentiality of her private information, and the loss of value of her private information. Id. ¶ 145. Plaintiff brings the following claims against Delta Dental on her own behalf and on behalf of a proposed class of similarly situated people: (1) negligence; (2) breach of fiduciary duty; (3) breach of confidence; (4) unjust enrichment; (5) violations of the California Invasion of Privacy Act, Cal. Penal Code § 631(a); (6) violations of California’s Unfair Competition Law, Cal. Bus. & Prof. Code § 17200, et seq.; and (7) violations of the Electronic Communications Privacy Act, 18 U.S.C. § 2511(1), et seq. Plaintiff filed this action in the San Francisco Superior Court on February 18, 2025. Dkt. No. 1-1. On March 26, 2025, Delta Dental removed the action to federal court, arguing that “Federal Jurisdiction is Proper” because “one of Plaintiff’s causes of action arises under federal law,” namely her claim under the Electronic Communications Privacy Act. See Dkt. No. 1 at 3. About a week after it removed the case, Delta Dental moved to dismiss all claims under Rule 12(b)(1) for lack of Article III standing and, in the alternative, under Rule 12(b)(6) for failure to state a claim. Dkt No. 13. In its response to Delta Dental’s motion, plaintiff argues that Delta Dental’s choice to move to dismiss for lack of Article III standing about a week after it removed the case is a “dubious” tactic that has been criticized by federal courts across the country as a waste of time and judicial resources. See Dkt. No. 18 at 4 (collecting authorities). Plaintiff contends that she has alleged injuries-in-fact sufficient to confer standing under Article III and that Delta Dental could, therefore, satisfy its burden to establish that federal jurisdiction is proper. Plaintiff further argues that, if Delta Dental refuses to satisfy that burden, then the only appropriate course of action is to A suit may be removed from state court to federal court only if the federal court would have had subject matter jurisdiction over the case. See 28 U.S.C. § 1441(a); see also Caterpillar Inc. v. Williams, 482 U.S. 386, 392 (1987) (“Only state-court actions that originally could have been filed in federal court may be removed to federal court by the defendant.”). “If at any time before final judgment it appears that the district court lacks subject matter jurisdiction, the case shall be remanded.” 28 U.S.C. § 1447(c); see also Gaus v. Miles, Inc., 980 F.2d 564, 566 (9th Cir. 1992) (“Federal jurisdiction must be rejected if there is any doubt as to the right of removal in the first instance.”). Article III standing is a core component of a court’s jurisdiction, without which a case cannot remain in federal court. See Cetacean Cmty. v. Bush, 386 F.3d 1169, 1174 (9th Cir. 2004) (“A suit brought by a plaintiff without Article III standing is not a ‘case or controversy,’ and an Article III federal court therefore lacks subject matter jurisdiction over the suit.”); see also TransUnion LLC v. Ramirez, 141 S. Ct. 2190, 2203–07 (2021) (discussing Article III standing). Notably, “[t]he party invoking federal jurisdiction bears the burden of establishing” Article III’s injury, redressability, and causation requirements. Lujan v. Defs. of Wildlife, 504 U.S. 555, 561 (1992); see also Jones v. Ford Motor Co., 85 F.4th 570, 573 (9th Cir. 2023) (“Upon removal, the burden to demonstrate Article III jurisdiction shifts to the Defendant as [t]he party invoking federal jurisdiction.”) (internal quotations omitted). If a “district court is confronted with an Article III standing problem in a removed case—whether the claims at issue are state or federal— the proper course is to remand for adjudication in state court.” Davidson v. Kimberly-Clark Corp., 889 F.3d 956, 970 n.6 (9th Cir. 2018) (citing 28 U.S.C. § 1447(c)). A. Article III Standing As the party that removed the case and is invoking federal jurisdiction, Delta Dental bears the burden of showing that Plaintiff has alleged an injury-in-fact sufficient to confer Article III standing. See Jones, 85 F.4th at 573. It has not satisfied that burden. To the contrary: in its 13 at 1 (arguing that the complaint is “devoid of any plausible allegations of injuries-in-fact sufficient . . . to confer standing under Article III”); Dkt. No. 19 at 3 (same). Where, as here, the removing party fails or declines to satisfy its burden to establish Article III standing, subject matter jurisdiction is in doubt and remand is appropriate, whether or not the plaintiff filed a motion for remand. See Polo v. Innoventions Int’l, LLC, 833 F.3d 1193, 1196 (9th Cir. 2016) (“[I]f at any time before final judgment it appears that the district court lacks subject matter jurisdiction, the case shall be remanded. . . . No motion [for remand], timely or otherwise, is necessary.”) (internal citation omitted); Yeh v. Twitter, Inc., No. 23-CV-01790-HSG, 2023 WL 8429799, at *4 (N.D. Cal.
