Beth Bowen v. Energizer Holdings, Inc.

FOR PUBLICATION UNITED STATES COURT OF APPEALS FOR THE NINTH CIRCUIT BETH BOWEN, Individually and on No. 23-55116 Behalf of All Others Similarly Situated, D.C. No. 2:21-cv-04356Plaintiff-Appellant, MWF-AGR v. OPINION ENERGIZER HOLDINGS, INC.; EDGEWELL PERSONAL CARE COMPANY; EDGEWELL PERSONAL CARE BRANDS, LLC; PLAYTEX PRODUCTS, INC.; SUN PHARMACEUTICALS, LLC, Defendants-Appellees. Appeal from the United States District Court for the Central District of California Michael W. Fitzgerald, District Judge, Presiding Argued and Submitted May 13, 2024 Pasadena, California Filed October 1, 2024 2 BOWEN V. ENERGIZER HOLDINGS, INC. Before: Ronald Lee Gilman,* Ronald M. Gould, and Salvador Mendoza, Jr., Circuit Judges. Opinion by Judge Mendoza SUMMARY** Article III Standing The panel reversed the district court’s order dismissing, pursuant to Fed. R. Civ. P.12(b)(1), Beth Bowen’s suit for lack of Article III standing in her action alleging that the Banana Boat sunscreen that she bought contained dangerous levels of benzene, contrary to Defendants’ representations that the products were safe, in violation of various California statutes. Defendants moved to dismiss Bowen’s suit by raising a factual challenge to Bowen’s Article III standing by submitting evidence to undermine Bowen’s allegations that small amounts of benzene were unsafe. In response, Bowen submitted evidence that benzene in sunscreen, at any level, was dangerous. The panel held that the district court erred by failing to construe facts in Bowen’s favor and prematurely resolving merits issues. Although a district court faced with a factual * The Honorable Ronald Lee Gilman, United States Circuit Judge for the U.S. Court of Appeals for the Sixth Circuit, sitting by designation. ** This summary constitutes no part of the opinion of the court.

ENERGIZER HOLDINGS, INC. 3 challenge to its exercise of jurisdiction may resolve disputed facts as to purely jurisdictional questions, it may not do so when those jurisdictional questions are intertwined with the merits of a claim. Applying that standard, the panel held there was a clear overlap between Bowen’s asserted theory of Article III injury and the “economic injury” element of her claim under California’s False Advertising Law. Because the standing issue and substantive issues were so intertwined, resolution of genuinely disputed facts was inappropriate. The panel held that Bowen adequately established an injury in fact for purposes of Article III, and genuine disputes of material fact rendered dismissal on standing grounds inappropriate. Although the district court addressed only the first element of standing—injury in fact—the panel invoked its independent obligation to consider standing sua sponte, and considered the second and third elements of Article III standing. As to the second element, the panel held that Bowen met her burden to show that Defendants caused her injury, in part, through their alleged misrepresentation that the Banana Boat products she purchased were safe for their intended use. As to the third element, the panel held that Bowen established that her injury would likely be redressed by judicial relief at this stage. 4 BOWEN V. ENERGIZER HOLDINGS, INC. COUNSEL Kiley L.

OPINION MENDOZA, Circuit Judge: In his 1997 classic spoken-word song, Everybody’s Free (To Wear Sunscreen), Baz Luhrmann advises his audience to “Wear sunscreen,” telling listeners that it helps prevent skin cancer and that “[t]he long-term benefits of sunscreen have been proved by scientists.”1 Today, Plaintiff Beth Bowen calls Mr. Luhrmann’s advice into question, alleging that the Banana Boat sunscreen she purchased was adulterated with benzene, a carcinogen that scientists have — 1 — Baz Luhrmann, Everybody’s Free (To Wear Sunscreen), on Something for Everybody (Capitol Records 1997). Luhrmann’s song popularized the words of journalist Mary Schmich from her essay in the Chicago Tribune. See Mary Schmich, Opinion, Advice, Like Youth, Probably Just Wasted on the Young, Chi. Trib., June 1, 1997, https://www.chicago tribune.com/1997/06/01/advice-like-youth-probably-just-wasted-onthe-young-2/. BOWEN V. ENERGIZER HOLDINGS, INC. 5 determined can cause cancer. Bowen sued six defendants2 who manufacture, market, and distribute Banana Boat sunscreen, claiming violations of various California statutes, including California’s False Advertising Law. Bowen alleges that the Banana Boat bottles she bought contained dangerous levels of benzene, contrary to the Defendants’ representations that the products were safe. She also claims that Defendants failed to disclose on the products’ labelling that those products contain benzene. Defendants moved to dismiss Bowen’s suit pursuant to Federal Rule of Civil Procedure 12(b)(1), raising a factual challenge to Bowen’s Article III standing by submitting evidence to undermine Bowen’s allegations that small amounts of benzene in sunscreen is unsafe. In response, Bowen submitted evidence of her own to support her allegation that benzene in sunscreen, at any level, is dangerous. The district court considered the parties’ competing evidence, as it may when addressing a factual challenge to Article III standing, and ultimately granted Defendants’ motion, relying heavily on three documents created by or associated with the Food and Drug Administration (“FDA”). It held that “[i]n light of the [FDA] guideline permitting 2 [parts per million] of benzene in sunscreen, [Bowen] does not allege facts that tend to show a non-speculative increased health risk or actual economic harm” arising from her purchase of Banana Boat products. On appeal, Bowen argues that the district court erred by failing to construe disputed facts in her favor and — 2 — The defendants are Energizer Holdings, Inc., Edgewell Personal Care Company, Edgewell Personal Care Brands, LLC, Edgewell Personal Care, LLC, Playtex Products, Inc., and Sun Pharmaceuticals, LLC (collectively, “Defendants”). 6 BOWEN V. ENERGIZER HOLDINGS, INC. prematurely resolving merits issues. We agree. Although a district court faced with a factual challenge to its exercise of jurisdiction may resolve disputed facts as to purely jurisdictional questions, it may not do so when those jurisdictional questions are intertwined with the merits of a claim. When the jurisdictional and merits issues are inseparable, the court must treat a factual attack on jurisdiction as a motion for summary judgment and construe disputed issues of fact in favor of the nonmoving party. Applying that standard here, Bowen has adequately established an injury in fact for purposes of Article III. So we reverse the district court’s dismissal for lack of standing and remand for further proceedings. I. BACKGROUND A. Bowen Purchases Banana Boat Bowen is a Californian who bought several bottles of Banana Boat sunscreen from a Rite Aid pharmacy between 2017 and 2020. Relevant here, she purchased Banana Boat Ultra Sport Sunscreen SPF 100 (“Ultra Sport 100”), Banana Boat Ultra Sport Sunscreen SPF 50 (“Ultra Sport 50”), and Banana Boat Ultra Sport Sunscreen SPF 30 (“Ultra Sport 30”). For the most part, Bowen used the products and then discarded the bottles when empty. But Bowen kept one bottle of Ultra Sport 50, which she purchased and partially used in 2020. She had the contents of that bottle tested at a lab, which revealed that the bottle contained 0.29 parts per million (“ppm”) of benzene. Bowen also alleges that a nonparty pharmacy—Valisure—tested various Banana Boat products and found that they too contained benzene, including a bottle of Ultra Sport 100, which Valisure found to contain more than 0.1 ppm of benzene. BOWEN V. ENERGIZER HOLDINGS, INC. 7 Relying on various sources, including guidance from the FDA, Bowen alleges that “[b]enzene is a carcinogen that can cause cancer in humans,” and that “the application of sunscreen specifically increases the absorption rate of benzene through the skin.” Bowen’s complaint also cites a statement by Yale University researcher, clinician, and professor of dermatology Dr. Christopher Bunick, who opined that “[t]here is not a safe level of benzene that can exist in sunscreen products,” meaning that even trace amounts can be harmful.3 Dr. Bunick further explained: Considering that human skin has a large total surface area (~1.85 m2), and that ~28.5 g of sunscreen is needed per application to properly cover that skin surface, it follows then that there is not a safe level of benzene that can exist in sunscreen products. The total mass of sunscreen required to cover and protect the human body, in single daily application or repeated applications daily, means that even benzene at 0.1 ppm in a sunscreen could expose people to excessively high nanogram amounts of benzene. Bowen alleges that the risk of sunscreen contamination in Banana Boat has led to public concern and voluntary recalls. On May 25, 2021, for example, “Valisure filed a citizen petition with the [FDA] asking the agency to recall all batches of Banana Boat Sunscreen Products containing 0.1 ppm or more benzene . . . , including Banana Boat Ultra — 3 — Bowen quoted Dr. Bunick’s statements in her complaint and submitted a letter from third-party Valisure, LLC, which also contains Dr. Bunick’s statements. 8 BOWEN V. ENERGIZER HOLDINGS, INC. Sport Sunscreen SPF 100.” In July 2021, consumers filed a putative class action in the District of Connecticut against several of the same parties who are Defendants here, alleging claims for false advertising and unjust enrichment, among others, arising from the defendants’ failure to disclose the presence of benzene in Banana Boat products. See Clinger v. Edgewell Pers. Care Brands, LLC, No. 3:21-CV-1040, 2023 WL 2477499 (D. Conn. Mar. 13, 2023). In December 2021, while this case was pending before the district court, non-party Edgewell Personal Care Australia Party Ltd. issued a recall of “all batches” of several Banana Boat sunscreen sprays distributed in Australia because the Therapeutic Good Administration (“TGA”)—Australia’s equivalent to the FDA—“detected benzene at concentrations between 2.3 ppm and 5.2 ppm in four batches of the . . . products supplied in Australia.” “Although not every batch of the affected products were tested by the TGA, the company issued the recall ‘to reduce the risk to consumers’ of using a benzene-contaminated product.” Finally, Bowen alleges that on July 29, 2022, Defendant Edgewell Personal Care Company (“EPCC”) announced a voluntary recall of a Banana Boat product sold in the United States—Banana Boat Hair and Scalp Sunscreen Spray SPF 30. EPCC stated that the reason for the recall was that “unexpected levels of benzene came from the propellant that sprays the product out of the can.” EPCC further stated that “entire batches of the product were recalled on the basis of ‘unexpected levels of benzene’ found in samples of the product.” BOWEN V. ENERGIZER HOLDINGS, INC. 9 B. Bowen’s Lawsuit Bowen asserts nine California state-law claims in her operative Second Amended Complaint (“SAC”).4 She claims jurisdiction under the Class Action Fairness Act, 28 U.S.C. § 1332 (d)(2). Bowen alleges that Defendants (1) failed to indicate on the labels of their products that many Banana Boat products contain benzene, and (2) engaged in false or misleading advertising by stating that Banana Boat products are “safe” when used as directed. With regard to the former, Bowen alleges that “Defendants wrongfully advertised and sold the Sunscreen Products without any labeling to indicate to consumers that these products contain or may contain benzene.” Bowen further alleges that Defendants’ misconduct “includes representing in their labels that their Sunscreen Products contain only the ingredients listed in the label, which is untrue, and failing to make any mention that the Sunscreen Products are adulterated with benzene, a known human carcinogen.” With regard to the latter, Bowen alleges that Defendants engaged in “deceptive, untrue, and misleading advertising by representing that their Sunscreen Products (1) ‘provide today’s busy family with sun protection without worry when used and reapplied as directed,’ (2) offer ‘safe and effective sun protection,’ and (3) are ‘safe for [their] intended use — 4 — These claims are: (1) violation of California’s Unfair Competition Law (“UCL”); (2) violation of California’s False Advertising Law (“FAL”); (3) violation of the California Consumer Legal Remedies Act; (4) unjust enrichment/quasi contract; (5) negligent misrepresentation/omission; (6) breach of express warranty; (7) breach of implied warranty; (8) strict product liability under a failure to warn theory; and (9) strict product liability under a manufacturing defect theory. 10 BOWEN V. ENERGIZER HOLDINGS, INC. based on the formulation, testing results, and the long history of safe consumer use.’” Bowen also raises certain allegations explicitly related to Article III standing:5 Plaintiff would have never paid a premium for sunscreen products that contained or were at risk of containing the carcinogen benzene. Standing is satisfied by alleging economic injury. Here, Plaintiff suffered economic injury when she spent money to purchase sunscreen products she would not otherwise have purchased, or [would have] paid less for, absent Defendants’ misconduct, as alleged herein. Bowen further alleges that she “suffered a concrete and particularized injury, because [she was] denied the opportunity to make informed financial and healthcare decisions due to the Defendants’ misconduct,” and that she “instead unwittingly purchased and used sunscreen products [she] would [] not have otherwise purchased, or [would have] paid less for, absent Defendants’ misconduct.” C. Motion to Dismiss the SAC and the District Court’s Order Defendants moved to dismiss the SAC on several bases: Rule 12(b)(1), for lack of Article III standing; Rules 8 and 12(b)(6), for failure to state a claim; and Rule 9(b), for failure to plead her allegations grounded in fraud with particularity. Defendants argued that Bowen’s SAC should be dismissed — 5 — The district court had previously dismissed Bowen’s first amended complaint for lack of standing, with leave to amend. BOWEN V. ENERGIZER HOLDINGS, INC. 11 for several distinct reasons, but the district court considered only one—whether Bowen has Article III standing to invoke the jurisdiction of the federal courts. The district court concluded that, “[i]n light of the [FDA] guideline permitting 2 ppm of benzene in sunscreen, Plaintiff does not allege facts that tend to show a nonspeculative increased health risk or actual economic harm.” To reach that conclusion, the district court conducted a searching, three-part analysis with respect to the bottle of Ultra Sport 50 that Bowen purchased, which contained 0.29 ppm of benzene. First, it looked outside the SAC to documents produced or relied upon by the FDA, and it determined that they “impl[y] that manufacturers like Defendants may continue to release products that are adequately tested and contain less than 2 ppm of benzene.” The district court next considered whether Bowen had established standing under an “increased health risk” theory. The court reasoned that Bowen’s allegations, and the numerous sources cited in the SAC, “do not establish that .29 ppm of benzene in sunscreen creates a credible or substantial risk of [physical] harm.” Finally, the district court considered whether Bowen had standing under an “economic loss” theory. The court weighed Defendants’ evidence related to the amount of benzene that the FDA deems tolerable in sunscreen products against Bowen’s evidence related to the harmful nature of benzene, and it held that Bowen’s “alleged economic harm”—i.e., that she paid more than she would have had she known that Banana Boat contained benzene—“is premised on the speculative notion that the presence of 0.29 ppm of benzene, or any potential presence of benzene, makes the sunscreen unsafe.” Bowen timely appealed. She argues that the district court erred in its analysis under Rule 12(b)(1) by failing to 12 BOWEN V. ENERGIZER HOLDINGS, INC. construe disputed facts in her favor. Had the district court done so, Bowen contends, it would have found that she has Article III standing under both an increased health-risk theory and an economic-injury theory. II. JURISDICTION & STANDARD OF REVIEW We have appellate jurisdiction pursuant to 28 U.S.C. § 1291 . “We review a district court’s dismissal under Rule 12(b)(1) for lack of standing de novo.” Unified Data Servs., LLC v. Fed. Trade Comm’n, 39 F.4th 1200, 1209 (9th Cir. 2022); San Diego Cnty. Credit Union v. Citizens Equity First Credit Union, 65 F.4th 1012, 1022 (9th Cir. 2023) (“The existence of a case or controversy is a question of law we review de novo.”), cert. denied, 144 S. Ct. 190 (2023). III. DISCUSSION To satisfy Article III’s case or controversy requirement, a plaintiff must establish that she has standing to invoke the jurisdiction of the federal courts. TransUnion LLC v. Ramirez, 594 U.S. 413, 423 (2021). To do so, she “must show (i) that [s]he suffered an injury in fact that is concrete, particularized, and actual or imminent; (ii) that the injury was likely caused by the defendant; and (iii) that the injury would likely be redressed by judicial relief.” Id. (citing Lujan v. Defenders of Wildlife, 504 U.S. 555 , 560–61 (1992)). Here, the district court treated Defendants’ Rule 12(b)(1) motion to dismiss for lack of subject matter jurisdiction as a factual attack on standing,6 considered — 6 — A factual attack on jurisdiction “contests the truth of the plaintiff’s factual allegations, usually by introducing evidence outside the pleadings.” Leite v. Crane Co., 749 F.3d 1117, 1121 (9th Cir. 2014) (quoting Safe Air for Everyone v. Meyer, 373 F.3d 1035, 1039 (9th Cir. BOWEN V. ENERGIZER HOLDINGS, INC. 13 evidence outside of the pleadings, and resolved disputed issues of fact in favor of Defendants in determining that Bowen lacked standing. Bowen concedes, as she must, that the district court was permitted to consider evidence outside the pleadings. But she argues that the district court erred by failing to construe disputed questions of fact, which implicate the merits of her claims, in her favor. In response, Defendants contend that the relevant standard permitted the district court to resolve disputed issues of fact because this is not a case where a federal “statute provides the basis for both the court’s subject matter jurisdiction and plaintiff’s claim for relief.” Bowen’s appeal therefore raises two issues. The first is a threshold question: did the district court err by resolving disputed issues of fact in its Rule 12(b)(1) analysis? The answer to that first question informs the answer to the second: has Bowen shown Article III standing sufficient to withstand Defendants’ Rule 12(b)(1) motion? We address each in turn. A. Intertwining of Standing and the Merits The rules governing a factual challenge to standing under Rule 12(b)(1) provide that once a defendant has “contested ‘the truth of the plaintiff[’s] factual allegations,’ the [plaintiff] ha[s] the burden to ‘support [her] jurisdictional allegations with ‘competent proof.’” Friends of the Earth v. Sanderson Farms, Inc., 992 F.3d 939, 944 (9th Cir. 2021) (quoting Leite v. Crane Co., 749 F.3d 1117, 1121 (9th Cir. 2004)). A “facial attack,” by contrast “accepts the truth of the plaintiff’s allegations but asserts that they ‘are insufficient on their face to invoke federal jurisdiction.’” Id. (quoting Safe Air for Everyone, 373 F.3d at 1039 ). 14 BOWEN V. ENERGIZER HOLDINGS, INC. 2014)).7 If the “existence of jurisdiction turn[s] on disputed factual issues,” and those “jurisdictional disputes [are] not intertwined with the merits of the claim,” then “it [falls] to the district court to ‘resolve those factual disputes itself.’” Id. (quoting Leite, 749 F.3d at 1121–22, 1122 n.3). Conversely, when jurisdictional issues are “intertwined with an element of the merits of the plaintiff’s claim,” the court must treat the motion like a motion for summary judgment and “leave the resolution of material factual disputes to the trier of fact.” Leite, 749 F.3d at 1122 . Accordingly, we must first answer the question posed by Friends of the Earth: are Bowen’s allegations relating to standing “separable from the merits of the case”—such that the district court was free to “resolv[e] factual disputes if necessary”—Jones v. L.A. Cent. Plaza LLC, 74 F.4th 1053 , 1057 n.2 (9th Cir. 2023), or are they “intertwined with an element of the merits of the plaintiff’s claim,” such that the district court was required to “leave the resolution of material factual disputes to the trier of fact,” Leite, 749 F.3d at 1122 ? As we reasoned in Safe Air for Everyone, “jurisdictional issue[s] and substantive issues” are deemed “intertwined [when] the question of jurisdiction is dependent on the resolution of factual issues going to the merits.” 373 F.3d at 1039 . We have concluded that merits issues and jurisdictional issues are intertwined—and thus, that the district court may not resolve disputed factual issues on a factual challenge to jurisdiction—under several circumstances. “Such an intertwining of jurisdiction and merits may occur when,” for example, “a party’s right to recovery rests upon the interpretation of a federal statute that — 7 — Facial challenges, by contrast, are adjudicated under the familiar Rule 12(b)(6) standard. Leite, 749 F.3d at 1121 . BOWEN V. ENERGIZER HOLDINGS, INC. 15 provides both the basis for the court’s subject matter jurisdiction and the plaintiff’s claim for relief.” Williston Basin Interstate Pipeline Co. v. An Exclusive Gas Storage Leasehold & Easement, 524 F.3d 1090, 1094 (9th Cir. 2008) (citing Safe Air for Everyone, 373 F.3d at 1039 ). Jurisdiction and substance might also be intertwined when the claim at issue arises under the Constitution. See Roberts v. Corrothers, 812 F.2d 1173, 1177 (9th Cir. 1987). And, in the context of a motion to remand to state court a case involving federal-officer removal jurisdiction, the district court may not resolve a “factual dispute material to [federalofficer] jurisdiction [that] is intertwined with an element of the plaintiff’s claim.” DeFiore v. SOC LLC, 85 F.4th 546 , 553 (9th Cir. 2023). We have considered on several occasions, though not expressly decided, whether a district court may resolve disputed issues of fact relating to Article III standing when a plaintiff’s allegations concerning standing are intertwined with allegations concerning an element of her claim. In Jones, for example, we noted that resolving “Article III standing issue[s] under the guise of a Rule 12(b)(1) motion, rather than a summary-judgment motion under Rule 56, might be inappropriate if those jurisdictional issues are ‘intertwined with the merits.’” 74 F.4th at 1057 n.2. Similarly, in Wood v. City of San Diego, we considered the plaintiff’s argument that, because the merits of her claim were intertwined with Article III standing issues, a “jurisdictional finding of genuinely disputed facts” was inappropriate. 678 F.3d 1075, 1084 (9th Cir. 2013) (quoting Safe Air for Everyone, 373 F.3d at 1039 ). But we left the resolution of that issue for another day because the plaintiff’s case was subject to dismissal regardless of the applicable standard. Id. at 1085 . Likewise, in Friends of the Earth, we 16 BOWEN V. ENERGIZER HOLDINGS, INC. implicitly suggested that when the merits of a plaintiff’s claims are intertwined with an Article III standing issue, the district court may not resolve disputed issues of fact. See 992 F.3d at 944 . But we did so by holding the inverse: “Importantly, because the jurisdictional disputes [as to standing] were not intertwined with the merits of the claim[,] . . . it fell to the district court to ‘resolve [the] factual disputes itself.’” Id. (quoting Leite, 749 F.3d at 1121–22, 1122 n.3) (emphasis added). Accordingly, we conclude that the applicable standard for a Rule 12(b)(1) motion that raises a factual challenge to Article III standing tracks the standard set forth in cases like Williston Basin, 524 F.3d 1094 ; Roberts, 812 F.2d at 1177 ; and DeFiore, 85 F.4th at 553.8 As with a motion for summary judgment, when a court is faced with a factual attack on standing pursuant to Rule 12(b)(1), the court “must leave the resolution of material factual disputes to the trier of fact when the issue of [standing] is intertwined with an element of the merits of the plaintiff’s claim.” Leite, 749 — 8 — In so holding, we join the Tenth and Eleventh Circuits. See Baker v. USD 229 Blue Valley, 979 F.3d 866, 874 (10th Cir. 2020) (“We find standing intertwined with the merits when we cannot resolve a jurisdictional question without addressing the merits of a substantive claim.”); PDVSA US Litig. Tr. v. LukOil Pan Ams. LLC, 991 F.3d 1187, 1192 (11th Cir. 2021) (noting, on appeal from Rule 12(b)(1) challenge to Article III standing, that “[w]hen the jurisdictional basis of a claim is intertwined with the merits, the district court should apply a Rule 56 summary judgment standard when ruling on a motion to dismiss which asserts a factual attack on subject-matter jurisdiction”). BOWEN V. ENERGIZER HOLDINGS, INC. 17 F.3d at 1122 (citing Safe Air for Everyone, 373 F.3d at 1039– 40).9 1. Bowen’s Appeal We turn now to whether Bowen’s appeal raises intertwined standing and merits issues. In making that assessment, we consider whether “the question of [standing] is dependent on the resolution of factual issues going to the merits of [the] action.” See Safe Air for Everyone, 373 F.3d at 1039 (citation and internal quotation marks omitted). Here, Bowen alleges that she suffered an economic injury for purposes of Article III standing “when she spent money to purchase sunscreen products [that] she would not — 9 — We note that this rule is rooted in Supreme Court precedent involving “claim[s] under the constitution or federal statutes.” Safe Air for Everyone, 373 F.3d at 1039 (quoting Bell v. Hood, 327 U.S. 678 , 682– 83 (1946)). But the justification for this rule naturally extends to cases, like the present one, where a plaintiff invokes the diversity jurisdiction of the federal courts to resolve state-law claims. In Bell v. Hood, the Court highlighted the importance of preserving a federal forum for the vindication of federal rights, and it held that when a plaintiff sues “directly under the Constitution or laws of the United States, the federal court, but for [limited] exceptions . . . , must entertain the suit.” 327 U.S. at 681–82. Bell did not consider whether, in a case where the plaintiff invokes federal jurisdiction based on diversity of citizenship, 28 U.S.C. § 1332 , a district court’s obligation to “entertain the suit” is equally strong. But we have long held that “the district court has a ‘virtually unflagging’ obligation to exercise jurisdiction” once it attaches, regardless of whether the plaintiff invokes the court’s diversity jurisdiction under § 1332 or federal-question jurisdiction under § 1331. See Marlowe v. State Farm Fire & Cas. Co., 145 F.3d 1339 (9th Cir. 1998). The obligation of the federal courts to exercise jurisdiction when it attaches is no less important when a plaintiff invokes the federal court’s diversity jurisdiction, and we therefore find no basis to apply differing standards to factual attacks on Article III standing in cases when, as here, the court’s subject-matter jurisdiction stems from § 1332. 18 BOWEN V. ENERGIZER HOLDINGS, INC. otherwise have purchased, or [would have] paid less for, absent Defendants’ misconduct.” And she alleges that Defendants’ misconduct includes both their failure to indicate on their products’ ingredient lists that many of them contain benzene and their misleading advertising, which states that Banana Boat products are “safe” to use as directed. In essence, she seeks a remedy for an economic injury, based on actual fraud and fraud by omission. Where, as here, plaintiffs in a false-advertising case “‘contend that [they] paid more for [a product] than they otherwise would have paid, or bought it when they otherwise would not have done so’ they have suffered an Article III injury in fact.” Hinojos v. Kohl’s Corp., 718 F.3d 1102 , 1104 n.3 (9th Cir. 2013) (quoting Mazza v. Am. Honda Motor Co., 666 F.3d 581, 595 (9th Cir. 2012)). We sometimes call this an “overpayment theory.” McGee v. SL Snacks Nat’l, 982 F.3d 700, 706 (9th Cir. 2020) (“[O]verpayment is a viable theory of economic injury.”). A plaintiff proceeding on an overpayment theory of Article III standing typically must “allege that [the defendant] made false representations—or actionable non-disclosures—about [the product].” Id. at 707 .10 Of course, whether Defendants made “false representations” or “actionable non10 In McGee, we noted that it is an open question whether the plaintiff’s theory of Article III standing—that “a plaintiff may rely on an overpayment theory of economic injury in a case that does not involve misrepresentations”—was viable and found that it “appears to find some support” in our precedent and Third Circuit precedent. 982 F.3d at 707 (citing Birdsong v. Apple, Inc., 590 F.3d 955 (9th Cir. 2009), and In re Johnson & Johnson Talcum Powder Prod. Mktg., Sales Prac. & Liab. Litig., 903 F.3d 278 , 290 & n.15 (3d Cir. 2018)). But we need not answer the question left open in McGee today because Bowen alleges that Defendants made misrepresentations with respect to Banana Boat and benzene. Cf. McGee, 982 F.3d at 707 . BOWEN V. ENERGIZER HOLDINGS, INC. 19 disclosures,” id., is also a merits issue central to Bowen’s false-advertising claim. After all, one of the elements that Bowen must establish to prevail on a claim under California’s FAL is an “economic injury”—i.e., “that she was exposed to false information about the product purchased, which caused the product to be sold at a higher price, and that she ‘would not have purchased the goods in question absent this misrepresentation.’” Davidson v. Kimberly-Clark Corp., 889 F.3d 956, 966 (9th Cir. 2018) (quoting Hinojos, 718 F.3d at 1105 ).11 Accordingly, there is a clear overlap between Bowen’s asserted theory of Article III injury and the “economic injury” element of her FAL claim. And Bowen’s allegations relating to standing are not “separable from the merits of the case,” such that the district court was free to “resolv[e] factual disputes.” See Jones, 74 F.4th at 1057 n.2. To resolve the Article III standing issue—whether Defendants “made false representations[,] or actionable nondisclosures[,] about [the product],” McGee, 982 F.3d at 707—would necessarily require us to resolve the merits issue—whether Defendants’ representations and nondisclosures are “actionable” under California law. Because “the [standing] issue and substantive issues are so intertwined,” resolution of “genuinely disputed facts is inappropriate.” See Safe Air for Everyone, 373 F.3d at 1039 ; cf Friends of the Earth, 992 F.3d at 944 . So we must assess Defendants’ motion as we would a motion for summary — 11 — For the avoidance of doubt, we note that whether a plaintiff has satisfied the economic-injury element of a substantive claim under California’s FAL is a distinct inquiry from whether a plaintiff satisfies Article III’s standing requirements. A plaintiff’s failure to satisfy the strictures of California law is by no means determinative of whether a plaintiff has satisfied the strictures of Article III. 20 BOWEN V. ENERGIZER HOLDINGS, INC. judgment, and “leave the resolution of material factual disputes [regarding Article III standing] to the trier of fact.” Leite, 749 F.3d at 1122 . B. Whether Bowen Has Established Article III Standing Applying a summary judgment standard to Defendants’ Article III challenge, we conclude that genuine disputes of material fact render dismissal on standing grounds improper. The district court considered only the first element of Article III standing—whether Bowen had established an injury in fact. It answered “no” even though Bowen alleged that “she spent money to purchase sunscreen products she would not otherwise have purchased, or [would have] paid less for, absent Defendants’ misconduct[.]” The district court held that “[i]n light of the [FDA] guideline permitting 2 ppm of benzene in sunscreen, Plaintiff does not allege facts that tend to show . . . actual economic harm.” The district court’s decision suffers from two errors. First, the district court mistakenly required Bowen to show that Banana Boat was noncompliant with FDA guidelines in order to establish injury under an economic-harm theory. Second, to reach the conclusion that 0.29 ppm of benzene in sunscreen is “safe,” the district court improperly weighed disputed evidence. We address each error in turn. First, Bowen’s theory of injury in fact finds ample support in our precedent. In Hinojos, we considered whether a plaintiff who alleged claims under California’s UCL, FAL, and CLRA had Article III standing. 718 F.3d at 1102 . The Hinojos plaintiff alleged that he “bought merchandise from a Kohl’s Department Store that he would not have purchased had he not been misled by advertisements stating that the merchandise was marked down from a fictitious ‘original’ or ‘regular’ price.” Id. at 1101. We found that “[t]here is no BOWEN V. ENERGIZER HOLDINGS, INC. 21 difficulty in this case regarding Article III injury in fact” because “when, as here, ‘[p]laintiffs contend that [they] paid more for [a product] than they otherwise would have paid, or bought it when they otherwise would not have done so’[,] they have suffered an Article III injury in fact.” Hinojos, 718 F.3d at 1104 n.3 (quoting Mazza, 666 F.3d at 595 ); see also Mazza, 666 F.3d at 595 (holding at the motion for class certification stage that “[t]o the extent that class members were relieved of their money by Honda’s deceptive conduct—as plaintiffs allege—they have suffered an injury in fact” for purposes of Article III standing (internal quotation marks and citation omitted)). Here, Bowen alleges that when “purchasing the sunscreen products, [she] reviewed the accompanying labels and disclosures, and understood them as representations and warranties by the manufacturer that the sunscreen products were properly manufactured, free from defects, safe for their intended use, and not adulterated or misbranded.” Bowen “relied on these representations and warranties in deciding to purchase the sunscreen products manufactured by Defendants, and these representations and warranties were part of the basis of the bargain.” But the bottle of Ultra Sport 50 that Bowen purchased in 2020 contained the alleged carcinogen benzene. And although Bowen discarded the Ultra Sport 100 bottle that she purchased without testing it, she alleges that Ultra Sport 100 has been tested by Valisure and found to contain at least 0.1 ppm of benzene. Had Bowen “known that any amount of benzene was or risked being contained in the sunscreen products she purchased, she would not have purchased and used the products at all or would have paid significantly less for them.” Finally, Bowen alleges that she “suffered economic injury when she spent money to purchase sunscreen products she would not 22 BOWEN V. ENERGIZER HOLDINGS, INC. otherwise have purchased, or paid less for, absent Defendants’ misconduct, as alleged herein.” Under Hinojos and Mazza, these allegations outline a theory of economic injury that qualifies as an injury in fact under established Article III standing caselaw. Hinojos, 718 F.3d at 1104 n.3; Mazza, 666 F.3d at 595 ; see also Reid v. Johnson & Johnson, 780 F.3d 952, 958 (9th Cir. 2015) (quoting POM Wonderful LLC v. Coca-Cola Co., 573 U.S. 102 , 108 (2014) (“A consumer who is hoodwinked into purchasing a disappointing product may well have an injury-in-fact cognizable under Article III. . . .”)). The district court cited Hinojos but found it materially distinguishable. The court characterized the standing analysis in Hinojos as follows: “In Hinojos, the plaintiff alleged he suffered economic harm because he would not have purchased merchandise if not for the inflated ‘regular’ price[;] it is not hypothetical that the fictitiously high ‘regular’ prices made the merchandise seem like more a bargain.” The district court then attempted to juxtapose Bowen’s alleged injury: “Unlike the concrete premise[] for the economic harm[] in . . . Hinojos, Bowen’s alleged economic harm is premised on the speculative notion that the presence of 0.29 ppm of benzene, or any potential presence of benzene, makes the sunscreen unsafe.” But the distinction drawn by the district court is immaterial to the standing analysis under Bowen’s economic-harm theory of injury. The district court relies on the mistaken premise that Bowen’s theory of Article III injury requires her to prove that benzene in the quantity found in the bottle of Ultra Sport 50 that she purchased—0.29 ppm—is unsafe. That is not the case. Instead, Bowen need prove only that she “paid more for [the product] than [she] otherwise would have paid, or bought it when [she] otherwise would not have done so,” BOWEN V. ENERGIZER HOLDINGS, INC. 23 Hinojos, 718 F.3d at 1104 n.3, absent Defendants’ “false representations—or actionable non-disclosures—about [the product,]” McGee, 982 F.3d at 706 . Second, under Bowen’s theory of standing, the evidence presented by the parties gives rise to disputes of fact with respect to whether Defendants made actionable misrepresentations about Banana Boat sunscreen. In finding that Bowen failed to establish a non-speculative injury, the district court gave controlling weight to three documents: (1) a document produced by the International Conference on Harmonization (“ICH”) titled “Impurities: Guidelines for Residual Solvents Q3c” (“ICH Q3C”); (2) an FDA news release from December 2021 titled “FDA alerts drug manufacturers to the risk of benzene contamination in certain drugs” (“FDA Alert”); and (3) the Frequently Asked Questions section of the FDA’s website—specifically, the page titled “Frequently Asked Questions on Benzene Contamination in Drugs” (“FDA FAQ”). Even without considering Bowen’s countervailing evidence, those documents do not resolve the question of whether benzene is actually unsafe at any level. Those sources merely highlight the FDA’s view that benzene “should not be employed in the manufacture of . . . drug products because of their unacceptable toxicity or their deleterious environmental effect. However, if their use is unavoidable in order to produce a drug product with a significant therapeutic advance, then their levels should be restricted” to 2 ppm, “unless otherwise justified.” (emphasis added). The FDA is not stating, as Defendants argue and the district court held, that products containing less than 2 ppm of benzene are safe, full stop. Characterizing such products as safe runs counter to the agency’s caveat-laden guidance. Instead, the FDA has expressed the view that benzene should 24 BOWEN V. ENERGIZER HOLDINGS, INC. not be used in products unless its “use is unavoidable . . . to produce a drug with a significant therapeutic advance” or “unless otherwise justified”; the FDA FAQ posted to the FDA’s website suggests that “[d]rug manufacturers with a risk for benzene contamination should test their drugs accordingly and should not release any drug product batch that contains benzene above 2 parts per million (ppm)”; and that manufacturers “should contact FDA using the information provided in FDA’s [A]lert if their testing reveals benzene in a product.” Accordingly, there is inconsistency even within the documents put forth by Defendants and relied upon by the district court: on the one hand, the FDA tells manufacturers not to deliberately put benzene in drugs unless it is “unavoidable” because of its “unacceptable toxicity;” on the other hand, the FDA advises manufacturers that if their drugs become contaminated with benzene, they should not release batches with more than 2 ppm benzene. Hardly a ringing endorsement for the proposition that products with less than 2 ppm benzene are “safe.” The FDA guidance does not establish as a matter of law that sunscreen with benzene levels under 2 ppm is safe for human use.12 Bowen submitted evidence in opposition to Defendants’ motion to dismiss that raises further disputes of material fact as to whether Defendants’ assertion that Banana Boat — 12 — The district court relied on the FDA Alert and FDA FAQ not as sources of federal law preempting Bowen’s state-law claims, but instead as factual evidence that benzene levels under 2 ppm in sunscreen is safe. This was wise, as neither document has the force of federal law: “[I]t cannot be disputed that the FAQ section of a federal website is not a source of ‘federal law,’ nor would an interpretation announced there be subject to deference by a court.” Ariz. Dream Act Coal. v. Brewer, 757 F.3d 1053, 1073 (9th Cir. 2014) (Christen, J., concurring). BOWEN V. ENERGIZER HOLDINGS, INC. 25 products are “safe” is a “misrepresentation.” See McGee, 982 F.3d at 707 . Chiefly, Bowen proffered Dr. Bunick’s opinion that “there is not a safe level of benzene that can exist in sunscreen products,” and “even benzene at 0.1 ppm in a sunscreen could expose people to excessively high nanogram amounts of benzene.” And although a plaintiff typically need not support her allegations with evidence at the pleading stage, Bowen did so here by providing evidence that the Ultrasport 50 bottle she bought contained 0.29 ppm benzene and that the Ultrasport 100 product she bought was tested by a third-party and contained more than .1 ppm benzene. The district court held that “Dr. Bunick’s statement that 0.1 ppm of benzene ‘could expose people to excessively high amounts’ creates only a speculative risk of harm, especially in light of the FDA’s concentration limit of 2 ppm of benzene.” But it is not the district court’s role to weigh evidence that implicates both jurisdictional and merits issues; “contested evidence is viewed in the light most favorable to the nonmoving party.” Johnson, 79 F.4th at 999. In this case, that is Bowen. When consumers like Bowen enter the marketplace, they have options. Faced with two sunscreens in the skincare aisle of a pharmacy—one with benzene, the other with no benzene—it is perfectly reasonable that the consumer would avoid the product containing benzene, as Bowen alleges that she would have absent Defendants’ alleged false advertising. The FDA tells manufacturers not to put benzene in drugs unless doing so is unavoidable. The Valisure letter that Bowen submitted quotes Dr. Bunick as opining that “there is not a safe level of benzene that can exist in sunscreen products,” and “even benzene at 0.1 ppm in a sunscreen could expose people to excessively high nanogram amounts of benzene.” And Defendant EPCC has voluntarily recalled 26 BOWEN V. ENERGIZER HOLDINGS, INC. batches of Banana Boat sunscreen sold in the United States that the company asserted contained “trace”—though undisclosed—amounts of benzene.13 In light of this record evidence, factual disputes remain as to the truthfulness of the Defendants’ representations that the Banana Boat products were “safe,” and as to whether their omission of benzene from the bottles’ labeling were misrepresentations. Accordingly, the district court erred in dismissing Bowen’s SAC for failure to establish an injury in fact for purposes of Article III standing.14 1. Article III Causation and Redressability Although the district court addressed only the first element of standing—injury in fact—“we have an independent obligation to consider” standing sua sponte. Am. C.L. Union of Nev. v. Lomax, 471 F.3d 1010, 1015 (9th Cir. 2006) (internal quotation marks and citation omitted). — 13 — We note that, although Bowen did not provide evidence to support the allegation that the Ultrasport 30 she bought, used, and discarded contained benzene, she was not required to do so to withstand Defendants’ motion to dismiss. Because Defendants did not produce evidence showing that the Ultra Sport 30 did not contain benzene, we review the issue of whether the Ultra Sport 30 contained benzene under the rubric for a facial challenge to jurisdiction, i.e., the Rule 12(b)(6) standard. Leite, 749 F.3d at 1121 . And, in light of her allegations about the other Banana Boat spray products she purchased that contained benzene and allegations regarding Defendant EPCC’s recall of another SPF 30 Banana Boat product due to “unexpected levels of benzene [in] the propellant that sprays the product out of the can,” Bowen has plausibly alleged that the Ultrasport 30 bottle that she purchased and used contained benzene. — 14 — Because Bowen has established an injury in fact under an economicharm theory, we need not, and do not, address Bowen’s argument that the district court erred in determining that she failed to establish an injury in fact under a physical-harm theory. BOWEN V. ENERGIZER HOLDINGS, INC. 27 So we consider whether Bowen has satisfied the second and third elements of Article III standing: “(ii) that the injury was likely caused by the defendant; and (iii) that the injury would likely be redressed by judicial relief.” TransUnion LLC, 594 U.S. at 423 . Bowen alleges that Defendants caused her injury, in part, through their alleged misrepresentation that the Banana Boat products she purchased are safe for their intended use. As set forth above, whether the Banana Boat bottles that Bowen purchased contained unsafe levels of benzene is a disputed issue of fact. Bowen cites Dr. Bunick’s opinion that “[t]here is not a safe level of benzene that can exist in sunscreen products.” Accordingly, whether Defendants “made false representations” about the safety of their products that “likely caused” Bowen’s economic injury is a disputed question of fact, see McGee, 982 F.3d at 707 , and Bowen has met her burden to satisfy the causation element of Article III standing at this juncture. Bowen has also met her burden to establish redressability. Defendants did not submit evidence in support of their Rule 12(b)(1) motion challenging redressability, and we therefore consider whether Bowen has established that element of standing under the 12(b)(6) rubric, which we apply to a facial challenge to jurisdiction. Leite, 749 F.3d at 1121 . Bowen plausibly alleges that she paid more for the Banana Boat products than she would have absent Defendants’ alleged misconduct, and she seeks damages for that alleged overpayment. Bowen also alleges that she intends to purchase Banana Boat products in the future, but only if they “are unadulterated and meet the advertising claims.” She further seeks to enjoin the Defendants “from distributing such false advertising and 28 BOWEN V. ENERGIZER HOLDINGS, INC. misrepresentations” as is alleged in the SAC.15 Bowen has therefore established that her injury “would likely be redressed by judicial relief” at this stage of the litigation. TransUnion LLC, 594 U.S. at 423 . IV. CONCLUSION For the foregoing reasons, we REVERSE the district court’s order dismissing Bowen’s suit for lack of Article III standing, and REMAND for further proceedings consistent with this opinion. — 15 — We note the Defendants’ assertion that “Plaintiff has no standing to prosecute claims on the basis of products she did not purchase,” and they contend that Plaintiff should not be allowed to pursue an injunction with respect to products that she did not buy. We decline Defendants’ invitation to prejudge these issues.
