*******************
A recent United States federal court decision from the Northern District of California in the ongoing In re Social Media Adolescent Addiction/Personal Injury Products Liability Litigation, MDL No. 3047 (N.D. Cal. Nov. 15, 2024) (“Social Media MDL”), slip op., suggests that social media companies will be required to continue to defend against public nuisance claims brought against them by local governments and school districts in fifteen states.
Last month, the MDL court denied defendants’ motion to dismiss, rejecting the arguments of a number of companies behind the major social media platforms used in the United States that the public nuisance claims asserted by school districts and local governments in sixteen different states were not cognizable under state law. Recently, there have been a number of this narrow common law tort to try to shift the costs of governmental services. The expansion sought in the Social Media MDL presents its own issues given nature of social media platforms and how they are used by minors.
A public nuisance is an act or condition that unreasonably disrupts a right shared by the general public, such as health, safety, or the use of communal resources. Unlike private nuisances, which affect individuals or small groups, public nuisances impact the entire community. Although social media may not be very old, never before have public authorities been permitted to seek damages from private companies that provide free social media platforms to the general public because of alleged public harms.
Here, the school districts and local governments allege that the Defendants’ social media platforms are “plausibly alleged to have contributed to negative health outcomes for [minor] students, causing foreseeable resource expenditures by the school districts to combat the alleged public health crisis.” Id. at 10. In evaluating this assertion, the Social Media MDL had to make an Erie prediction about whether the laws of sixteen states each provided a public nuisance remedy that covered plaintiffs’ theory. Without citing or acknowledging the restraint imposed by Erie, the Social Media MDL flipped the inquiry to focus on whether the states would “prohibit” the claims based on formally adopted limitations on the scope of public nuisance: “While public nuisance law remains in flux, the Court declines to import these limitations and hold that the supreme courts of the at-issue states would per se prohibit the kind of action brought by the school districts under the alleged facts of this case.” Slip op at 1-2. See also id. at 17 n.15. This is arguably not the proper inquiry under Fed. R. Civ. P. 12(b)(6) or Erie, but the framing of the inquiry largely determined the outcome here.
The Social Media MDL characterized the school districts’ injuries as unique, stemming from resource diversion rather than individual student harms, and upheld their claims of “special injury.” The recognition of a state law claim for a unique or special injury is for a state’s highest court or legislature, not for a federal court sitting in diversity, even if it is an MDL court. The court also found broad allegations of harm to public health and education were sufficient, even without any alleged interference with a traditional public right.
The court dismissed the claims asserted pursuant to the law of four states—Illinois, New Jersey, Rhode Island, and South Carolina—citing judicial reluctance in those states to expand public nuisance law, where state courts “express[ed] reluctance to expand public nuisance and thus counsel grant of the motion [to dismiss] on this ground” for Illinois, New Jersey, and Rhode Island. Id. at 5-7. The Court used a similar analysis in dismissing claims from South Carolina. Id. at 7-9.
With respect to the law of the other fifteen states at issue with these plaintiffs’ claims, the Social Media MDL manifestly struggled with the question of whether a theory of public nuisance can be used as a basis for recovery against the defendants:
Here, the question of whether a “product” even exists and upon which a products liability claim could survive remains hotly contested. Defendants in the related personal injury cases argue no product exists. In fact, social media platforms have been described as the “virtual public square.” Plaintiffs here also argue their claims “do not concern product liability law as they do not seek to recover for injuries suffered from a defective product.”
Id. at 18-19. Yet it ultimately let most of the claims survive dismissal.
The Blog has repeatedly expressed concern with the expansion of the public nuisance doctrine to cover drugs, devices and other products that do not qualify as a classic public nuisance. Damages sought by governmental entities have been tied to the cost of providing a range of governmental services historically provided to residents and funded by taxes, fees, and fines. Now, in litigation around the country—not just the Social Media MDL—plaintiffs have asked courts to treat free social media platforms as “products” for the purposes of public nuisance product liability. To the extent that courts answer in the affirmative, social media companies face a massive pool of plaintiffs who can allege that these platforms should bear the costs for a variety of second order consequences of damages incurred by a range of individuals and entities allegedly “harmed” by the use of social media by others.
During a hearing on this issue in May, the Social Media MDL struggled with how to resolve the question of whether local school districts can obtain awards for the alleged damages caused by students’ use of social media:
I don’t know if they have a claim… But I do know that the challenges they’re facing are real, they are significant, and they’re all tied back to these platforms.
Isaiah Poritz, Social Media a ‘Double-Edged Sword’ for Students, Judge Says, Bloomberg Law (May 17, 2024 1:38 PM). Of course, the existence of “challenges” for governments or society is not usually a sufficient reason to impose liability under any theory.
Notwithstanding these misgivings, six months later, the court rejected the argument that if free social media platforms are found to constitute public nuisances, it would lead to almost limitless liability for defendants:
Boundless liability is a question typically posed under proximate cause. As discussed, the Court is not persuaded by defendants’ concerns that permitting these claims of negligence and public nuisance will open the floodgates of liability. The school districts’ claims are grounded in their plausible allegations: defendants targeted minors at the school level, readily could foresee the strain their addictive platform design would impose on schools, and in some cases knew of those direct impacts to schools. See In re Social Media, 2024 WL 4673710, at *15. Proximate causation serves to limit the scope of liability only to the reach of defendants’ own actions.
Slip Op. at 17-18.
Comparing social media to for-sale products with demonstrated risk of injury, such as guns, vape pens, and drugs of abuses, the court noted:
Any interference with a public right can be reframed as a series of individual harms – after all, interference with a public right will harm individuals, not some amorphous collective. Here, defendants make their platforms available to the entire public. The alleged nuisance-causing conduct does not solely target individual children and schools, but is directed to the public, writ large.
Id. at 22-23.
From our perspective, this expansive view of the public nuisance doctrine would lead to almost limitless liability for social media platforms. This reasoning would permit virtually any public nuisance claim against social media platforms if a “public right” is alleged to have been infringed in some fashion.
A California state court recently reached the same conclusion in rejecting claims similar to those that the Social Media MDL allowed to proceed. In June, a southern California state court evaluating multiple school districts’ claims against social media companies found that the public nuisance doctrine did not apply to social media platforms and dismissed similar claims against the same defendants. See Social Media Cases, Case No. JCCP 5255, L.A. Super. Ct. (Filed June 7, 2024).
In evaluating claims that social media led to students exhibiting signs of addiction, depression and self-harm related to their use of social media, the state court found that the school districts had not alleged that even those potentially foreseeable harms were foreseeable causes of damage to school property or increased use of school resources. Id. at 17. The California Superior Court determined that social media cannot constitute a public nuisance:
The School Districts’ reliance on nuisance fails because the right not to be injured by the Defendants’ social media platform is a right personal to the minors who used Defendants’ platforms, and individual injuries to health have not been recognized by any of the four states in question as a basis for nuisance liability, even when the individual harms are considered collectively.
Id. at 25-26.
Importantly, the state court found that there was neither foreseeability, certainty nor a connection between the activities of the defendant and the harm alleged by plaintiffs, and therefore social media platforms has no duty to the school districts that was breached and led to their alleged damages. Id.
Similar to the concerns we have repeatedly raised, the state Superior Court opined that it “is hard to imagine how any business could function – or reasonably insure itself against potential losses – if its liability extends to all those who could reasonably be expected to interact with the individuals that are caused emotional harm by that business or institution.” Id. at 20. Thus, a state court was less willing than a federal court to expand state law to address an arguable gap.
The Social Media MDL has also interpreted federal law in a way that would allow for the potential imposition of significant liability. In October, the court held that a number of claims concerning platform functionalities were not shielded by Section 230 of the Communications Decency Act or the First Amendment. These included allegations concerning the absence of age verification mechanisms, inadequate parental control features, and default settings to limit screen time and usage frequency.
The court did find that other claims were barred by Section 230. Although plaintiffs claimed in connection with the public nuisance claims that they were not asserting product liability claims, their design defect claims related to the defendants’ role in publishing third-party content such as by hosting or distributing content and managing its timing and grouping were barred.
However, the court allowed claims not related to publishing, such as the defendants’ own actions or content creation, to proceed. Specifically, allegations regarding inadequate parental controls and poor management of notifications were not protected by Section 230 and could be pursued as negligence claims against social media platforms.
The net result of the Social Media MDL’s recent rulings is enough claims survived dismissal to keep the litigation rolling along, with bellwether trials set for October 2025.
