Lopez v. Mead Johnson Nutrition Company

Background

Dominique Lopez filed a proposed class action concerning the labeling of seven infant formulas: Enfamil A.R., Enfamil Gentlease, Enfamil Enspire Gentlease, Enfamil NeuroPro, Enfamil NeuroPro Sensitive, Enfamil Nutramigen, and Enfamil ProSobee. She alleged that the formulas contained arsenic, cadmium, and lead and that defendants did not disclose their presence or the material risk that the formulas contained them.

Lopez asserted seven causes of action: violations of California’s Unfair Competition Law, False Advertising Law, and Consumer Legal Remedies Act; breach of statutory and common-law implied warranties of merchantability; fraud by omission; and unjust enrichment.

Request for Judicial Notice

The court granted defendants’ request for judicial notice of a publicly available July 29, 2024 consent judgment involving Mead Johnson Nutrition Company and others in Alameda County Superior Court. The court stated that it would consider the consent judgment’s contents but would not assume that factual assertions in the judgment were true.

Primary Jurisdiction

Defendants argued that the court should dismiss the case or defer to the Food and Drug Administration because the agency had regulatory expertise concerning heavy-metal levels in infant formula. Lopez responded that her claims concerned deceptive labeling, not the scientific question of what levels make formula unsafe.

The court declined to apply the primary-jurisdiction doctrine. It concluded that the claims concerned whether product labels were misleading, an issue courts can decide, and found no reason to defer to the agency’s authority. The court also noted that the agency’s January 2025 guidance regarding lead levels was nonbinding and that the agency had not stated when it expected to issue final guidance on arsenic and cadmium levels in foods for young children.

Standing and Equitable Relief

Article III standing is the constitutional requirement that a plaintiff show a concrete injury connected to the defendant’s conduct that a court can remedy. Defendants argued that Lopez lacked standing to seek an injunction because she had not alleged a sufficiently likely future injury or a concrete intent to buy the formulas again.

The court found Lopez’s allegations sufficient to establish standing for injunctive relief. She alleged that she would be willing to buy Enfamil products in the future if she could be certain they did not contain, or face a material risk of containing, heavy metals, and that she could not rely on the packaging without corrective changes.

The court separately dismissed Lopez’s claims seeking restitution. It found that she had not alleged that she lacked an adequate remedy at law, which the court treated as a required condition for equitable relief. The court stated that her claims for injunctive relief under the Unfair Competition Law, False Advertising Law, Consumer Legal Remedies Act, fraud, and unjust enrichment could proceed at that stage.

Failure to State a Claim

A motion under Federal Rule of Civil Procedure 12(b)(6) tests whether a complaint alleges enough facts to state a legally recognized and plausible claim. The court held that Lopez had not plausibly alleged that defendants had a duty to disclose the heavy metals.

Under the standards applied by the court, a duty to disclose could arise if the alleged defect created an unreasonable safety hazard or if it was material, central to the product’s function, and met at least one additional factor identified in California law. The court found that Lopez had not plausibly alleged an unreasonable safety hazard. It reasoned that the complaint did not connect the alleged arsenic, cadmium, and lead levels to the health risks described, and did not establish that the levels exceeded safety thresholds or otherwise posed a danger to human health.

The court also found that Lopez had not plausibly alleged that the heavy metals affected the formulas’ central function. The formulas still functioned as food and were not alleged to be incapable of use by any consumer. In addition, the court found that the complaint did not adequately plead the additional factors required for a duty to disclose, including a fiduciary relationship, exclusive knowledge, or active concealment.

Based on the lack of a duty to disclose, the court dismissed Lopez’s fraud-based Unfair Competition Law claim and her Consumer Legal Remedies Act and False Advertising Law claims. The court also dismissed her fraud-by-omission claim because a duty to disclose is an element of that claim.

The court dismissed the unlawful-prong Unfair Competition Law claim because the alleged underlying violations of the Consumer Legal Remedies Act, False Advertising Law, fraud-by-omission theory, and implied warranty law were not adequately pleaded. It dismissed the unfair-prong claim because it overlapped with the deficient fraudulent and unlawful claims.

The court rejected defendants’ argument that Lopez lacked contractual privity for the implied-warranty claims because California recognizes an exception for food products, allowing an implied warranty of fitness for human consumption to run from the manufacturer to the ultimate consumer. Even so, the court dismissed both implied-warranty claims because Lopez had not plausibly alleged that the formulas were unsafe for human consumption or unfit for their ordinary purpose.

Finally, the court dismissed the unjust-enrichment claim because it relied on the same inadequately pleaded misrepresentation or omission allegations.

Consumer Legal Remedies Act Notice

The court addressed defendants’ alternative argument that Lopez had not provided the required pre-suit notice for a damages claim under the Consumer Legal Remedies Act. The court found that Lopez’s January 26, 2024 letter satisfied the notice requirement. Because the letter was sent more than 30 days before she initiated this California case, the court did not need to decide whether her earlier Illinois complaint also satisfied the requirement.

Disposition

The court granted defendants’ motion to dismiss and request for judicial notice. It ordered that any amended complaint be filed within 21 days of the order.
