INTEREST OF AMICI CURIAE1

Amici are the Product Liability Advisory Council

(PLAC) and American Tort Reform Association (ATRA). They and their members are concerned with attempts to subject industries that manufacture lawful

products to unprincipled liability for costs of societal

problems regardless of whether any of their conduct

proximately caused those alleged harms.

PLAC is a nonprofit professional association of

corporate members representing a broad crosssection of product manufacturers. PLAC contributes

to the improvement and reform of the law, with emphasis on the law governing the liability of manufacturers of products and those in the supply chain.

PLAC’s perspective is derived from the experiences

of a corporate membership that spans a diverse

group of industries in various facets of the manufacturing sector. In addition, several hundred leading

product litigation defense attorneys are sustaining

(non-voting) members of PLAC. Since 1983, PLAC

has filed over 1,200 amicus curiae briefs on behalf of

its members, presenting the broad perspective of

product manufacturers seeking fairness and balance

in the application and development of the law as it

affects product risk management.

ATRA is a broad-based coalition of businesses,

corporations, municipalities, associations, and professional firms that have pooled their resources to

1 Pursuant to Rule 37.6, counsel for amici affirm this brief was

not authored in whole or in part by counsel for any party and

that no person or entity, other than amici curiae, their members, or their counsel made a monetary contribution to the

preparation or submission of the brief.

promote reform of the civil justice system with the

goal of ensuring fairness, balance, and predictability

in civil litigation. For more than three decades,

ATRA has filed amicus briefs in cases involving important liability issues.

INTRODUCTION AND

SUMMARY OF ARGUMENT

In the Protection of Lawful Commerce in Arms

Act (PLCAA), Congress requires a showing that a

firearms manufacturer is the “proximate cause” of

harm for which a plaintiff seeks relief in order for the

plaintiff to proceed on the claim. This requirement

incorporates from tort law traditional notions of

proximate cause that have long served to protect

manufacturers engaged in lawful commerce from

unprincipled liability over their products. Thus, the

First Circuit’s erroneous holding on proximate causation has implications for the manufacture and sale

of many lawful products that have inherent risks related to their use and misuse. Indeed, comparable

lawsuits that have sought to force manufacturers

and sellers of lawful products—such as lead paint,

prescription medicines, and beverages in plastic bottles—to pay for state and local government efforts to

deal with risks consumers created with the lawfully

sold products (lead poisoning, drug abuse and litter).

Proximate causation has often been a key safeguard

against such unprincipled liability.

Accordingly, the Court should reverse the ruling

below. In doing so, it should correct several misstatements the First Circuit made about proximate

causation. First, the First Circuit based its ruling on

its finding that foreseeability alone could satisfy

proximate cause. See Estados Unidos Mexicanos v.

3

Smith & Wesson Brands, Inc., 91 F.4th 511, 534 (1st

Cir. 2024). However, as this Court has ruled, “foreseeability alone does not ensure the close connection

that proximate cause requires.” Bank of Am. Corp. v.

City of Miami, Fla., 581 U.S. 189, 202 (2017). Indeed,

cases similar to this one that have been brought by

local governments within the United States have

been dismissed for lack of proximate cause. See, e.g.,

City of Philadelphia v. Beretta U.S.A. Corp., 277 F.3d

415, 423 (3d Cir. 2002). Courts in these cases have

echoed this Court’s longstanding jurisprudence that

proximate cause requires “a direct relation between

the injury asserted and the injurious conduct alleged.” Id. (quoting Holmes v. Secs. Inv’r Prot. Corp.,

503 U.S. 258, 268-69 (1992)). And, governments in

these cases, as here, did not establish the necessary

proximate cause between selling lawful products and

public safety concerns over how some people used or

misused those products. See id.

Second, the court did not require Respondent to

identify any specific sales of the Petitioners’ products

that foreseeably caused the alleged harms. See Estados Unidos Mexicanos, 91 F.4th at 532 (“Of course,

the complaint does not allege defendants’ awareness

of any particular unlawful sale.”). Rather, Respondent pleaded foreseeability in aggregated generalities,

arguing that engaging in commerce of a product that

has known risks of harm satisfies proximate cause

whenever those harms occur—regardless of how remote the harms were from acts of the manufacturers

and sellers and whether these acts were unlawful.

And third, the complaint seeks to impose joint-andseveral liability on an industry for a broad range of

expenses rather than allege any particular manufacturer’s conduct caused any specific harm alleged.

4

American liability law, when grounded in proximate causation, does not impose blame or obligations

for product-based societal harms on industries that

put those lawful products into the stream of commerce. It may be foreseeable, for example, that underage individuals will purchase alcoholic beverages,

causing harm to themselves, their parents, or others,

but manufacturers and sellers of wine, beer and

spirts are not liable for these harms. See, e.g., Alston

v. Advanced Brands & Importing Co., 494 F.3d 562,

565 (6th Cir. 2007). It is also foreseeable that some

people will become obese or develop diabetes from

over-consuming certain foods, but companies that

sell those foods are not liable for these conditions.

Pelman v. McDonald’s Corp., 237 F. Supp. 2d 512,

538 (S.D.N.Y. 2003). Otherwise, there would be no

principled stopping point for this type of liability.

Many social issues related to products may be foreseeable in a general, aggregated sense. But, when

there are no specific incidents of harm directly

caused by the manufacturers or sellers, then those

manufacturers and sellers are not liable for the resulting harms. As here, the harms are often caused

by intervening acts—including criminal acts—of

third parties.

The First Circuit’s formulation of proximate causation, therefore, cannot stand; it violates basic tenets of American jurisprudence. Rather than subject

defendants to liability for harm they directly caused,

which is the essence of American tort law, these lawsuits will be used to generate revenue for local, state

and foreign governments from manufacturers and

sellers, regardless of fault, and frustrate federal and

state regulatory regimes that take considerable care

5

to manage public risks associated with sales of lawful products. Here, a foreign country is doing both.

Affirming the ruling below, therefore, could invite

foreign governments to sue American companies for

a wide-variety of social conditions. Such lawsuits

could destabilize the American economy and generate lawfare designed to hinder the competitiveness of

American manufacturers. This case could also inspire new speculative domestic lawsuits against

manufacturers and sellers of lawful products, including litigations that have already been largely dismissed for want of proximate cause.

For these reasons, as discussed in detail below,

amici urge the Court to reverse the ruling below and

hold that proximate cause cannot be satisfied here by

the acts of manufacturing, selling and marketing

lawful products, even when those products have

known, foreseeable risks. There is no doubt that gun

violence, just like lead poisoning, litter and drunk

driving, are critical public health and safety matters.

But, these facts alone do not give rise to deep-pocket

jurisprudence against market participants that did

not directly cause the harms alleged.

ARGUMENT

I. FORESEEABILITY IS NOT A SUBSTITUTE

FOR PROXIMATE CAUSATION

Proximate causation is “fundamental” to American tort law and “appl[ies] in any kind of case,” Dan

B. Dobbs, The Law of Torts § 180, at 443 n.2 (2001),

including this one where liability centers on whether

a legal violation is the “proximate cause of the harm

for which relief is sought,” 15 U.S.C. § 7903(5)(A)(iii).

The purpose of requiring a showing of proximate

6

cause is to “limit liability even where the fact of causation is clearly established,” including where manufacturers put into the stream of commerce products

that can cause harm, but the harms are not proximately caused by the manufacturers. Prosser &

Keeton on Torts 273 (5th ed. 1984). There must be a

“direct relation between the injury asserted and the

injurious conduct alleged.” Holmes, 503 U.S. at 26869. The specific injury the plaintiff sustained must

be the type of injury that a reasonable person would

see as a likely result of specific acts of misconduct.

This Court has held, contrary to the ruling below,

that “foreseeability alone does not ensure the close

connection that proximate cause requires.” Bank of

Am. Corp., 581 U.S. at 202. Foreseeability is a necessary, but not sufficient element of proximate cause.

Conduct “cannot meaningfully be viewed as ‘wrong’ if

the actor could not possibly have contemplated that

the action might produce the harm.” David G. Owen,

Figuring Foreseeability, 44 Wake Forest L. Rev.

1277, 1277-78 (2009). There are some harms that

may flow downstream from a defendant’s acts or the

manufacture of a line of products, but those harms

are too remote from these acts or manufacture to satisfy proximate causation. See Steamfitters Local Union No. 420 Welfare Fund v. Phillip Morris, Inc., 171

F.3d 912, 921 (3d Cir. 1999) (recognizing “an injury

that is too remote from its causal agent fails to satisfy tort law’s proximate cause requirement”); see also

Holmes, 503 U.S. at 268-69 (discussing the remoteness doctrine).

The concerns about over-reliance on foreseeability

to create liability, as here, has arisen under both

proximate causation and duty analyses. Consider

7

what is probably the most famous tort case, Palsgraf

v. Long Island R.R., in which Judge Cardozo found

that a railroad was not liable for an injury that occurred as a result of a sequence of events that began

with a railroad employee pushing a passenger carrying a small package into a departing train. 162 N.E.

99, 99 (N.Y. 1928). It may have been foreseeable that

the employee’s action could result in the pushed passenger falling and experiencing an injury or the

package dropping, resulting in property damage. But

the plaintiff’s injury—triggered by a fireworks explosion from the dropped package that ended in a

weighing scale tipping over and hitting a passenger

far down the platform—was simply too many steps

removed from the employee’s conduct for the railroad

to be legally responsible for that person’s harm.

Whether viewed as a decision rooted in duty or proximate causation, foreseeability that some harm will

be caused is not sufficient to establish liability for all

downstream injuries. A direct relationship between

the alleged misconduct and specific harms asserted

is required and missing in these remote cases.

Indeed, the California Supreme Court has recognized the legal predicament of over-relying on foreseeability to justify liability. See Dillon v. Legg, 441

P.2d 912 (Cal. 1968) (allowing liability for reasonably

foreseeable emotional harm). After foreseeability

ceased to provide any meaningful bounds to liability,

the court restrained its expansive doctrine, famously

observing that “there are clear judicial days on which

a court can foresee forever and thus determine liability but none on which that foresight alone provides a

socially and judicially acceptable limit on recovery of

damages for that injury.” Thing v. La Chusa, 771

P.2d 814, 830 (Cal. 1989). Applying a “pure foreseea-

8

bility” test in such cases, the court continued, had

failed to appreciate “the importance of avoiding the

limitless exposure to liability.” Id. at 821. In such instances, “foreseeability” was “not a realistic indicator

of potential liability” and did “not afford a rational

limitation on recovery.” Id. at 826. In short, foreseeability alone fails to put people on notice that they

may be liable for certain harms. See E. Enters. v. Apfel, 524 U.S. 498, 528-29 (1998) (liability “that could

not have been anticipated” stretches constitutional

limits); Pacific Mut. Life Ins. Co. v. Haslip, 499 U.S.

1, 43 (1991) (O’Connor, J., dissenting) (vagueness

doctrine applies to the common law).

In cases such as the one here, proximate cause

provides this “necessary limitation on liability.” Exxon Co. v. SOFEC, Inc., 517 U.S. 830, 838 (1996).

Without the constraint of proximate cause, tort law

would “produce extreme results,” because “[i]n a

philosophical sense, the consequences of an act go

forward to eternity, and the causes of an event go

back to the dawn of human events, and beyond.” Id.

(quoting Prosser and Keeton on the Law of Torts, supra, at 264). “Somewhere a point will be reached

when courts will agree that the link has become too

tenuous.” Id. (quoting Petition of Kinsman Transit

Co., 338 F.2d 708, 725 (2d Cir. 1964)); accord

Holmes, 503 U.S. at 287 (Scalia, J. concurring) (“Life

is too short to pursue every human act to its most

remote consequences; ‘for want of a nail, a kingdom

was lost’ is a commentary on fate, not the statement

of a major cause of action against a blacksmith.”).

That point has clearly been reached here, where the

harm was caused by unlawful acts of others.

9

Tortious acts of third parties are often considered

intervening causes that “occur after the defendant’s

conduct” and cut-off proximate causation. John L.

Diamond, Cases and Materials on Torts 256 (2001).

As a general rule, a party “may reasonably proceed

upon the assumption that others will obey the criminal law,” Keeton, supra, at 305, even though “there

are bad people in society who do bad things.”

Stahlecker v. Ford Motor Co., 667 N.W.2d 244, 251

(Neb. 2003). In Stahlecker, for example, a person alleged that the manufacturer of her vehicle and tire

could be subject to liability after a defective tire

stranded her at night in a remote location, exposing

her to risk of harm. See id. But these companies are

not the proximate cause of injuries caused by criminals who harm stranded drivers merely because the

companies sold car parts that failed. See id. at 259

(finding criminal acts of third parties were an “intervening cause which necessarily defeats proof of the

essential element of proximate cause”).

For these reasons, when individual plaintiffs have

sought to subject manufacturers to liability for criminal acts of others, the lack of proximate causation

has been determinative in dismissing claims. See,

e.g., Santiago v. Sherwin Williams Co., 3 F.3d 546,

550 (1st Cir. 1993). In Santiago, which involved allegations of lead poisoning against companies that sold

lead-based paint decades earlier, the court explained

that proximate cause subjects defendants to liability

“only for the harm they have caused” and separates

“tortfeasors from innocent actors.” Id. Proximate

cause requires much greater specificity in directly

connecting the manufacturers to the harms alleged.

In the lead paint cases, the third-party tortfeasors

10

were often landlords who allowed the paint to deteriorate to the point that the paint became hazardous.

In order to subject manufacturers to liability for

illegal acts of third parties—here, criminal acts of

Mexican drug cartels—the manufacturers must be

complicit in the illegal activities themselves. See Suchomajcz v. Hummel Chem. Co., 524 F.2d 19 (3d Cir.

1975) (manufacturer sold chemicals to retailer with

knowledge retailer would use them in selling illegal

firecracker kits). The requirement for such a direct

connection applies equally in public nuisance cases,

where complicity requires a manufacturer to have

specific knowledge about or instruct the consumer to

use, dispose of or misuse the product to create the

nuisance. See, e.g., In re Methyl Tertiary Ether Prods.

Liab. Litig., 725 F.3d 65, 121, 123 (2d Cir. 2013) (defendant “knew specifically that tanks in the New

York City area leaked,” “conducted ‘operations near

the relative geographic areas” of the wells at issue,”

and had “extensive involvement in the [local] gasoline market”). These courts found it is insufficient to

allege the manufacturer “knew of the dangers” and

“failed to tackle the problem” of others’ illegal acts.

In re Paraquat Prods. Liab. Litig., MDL No. 3004,

2022 WL 451898, at *11 (S.D. Ill. Feb. 14, 2022).

Cases, such as the one at bar, attempt to circumvent the burdens of proof that individuals face by

substituting governments as plaintiffs and seeking

derivative costs. They suggest it is foreseeable that

selling certain products and engaging in certain lawful sales, when aggregated, will lead to criminal activity and cause governments to spend resources

dealing with that criminal activity. The Court should

reject any such attempt to water down proximate

11

cause in government recoupment suits, which allege

acts and harms even further away from the misconduct that harmed the individuals. Proximate causation does not become clearer by pulling back the causation lens to the level of blurred generalities.

Here, Congress sought to ensure that such tenuous liability could not be used in this context, expressly stating that liability in cases such as this one

requires the defendants to violate the law and for

this violation to be the “proximate cause of the harm

for which relief is sought.” 15 U.S.C. § 7903(5)(A)(iii).

The legislative intent could not be clearer. Congress

enacted the PLCAA to stop a rash of cases similar to

the one here. State and local governments in the

United States were seeking to subject this industry

to the same types of damages as in this case. Most of

those cases rightly failed, including on proximate

causation grounds. See, e.g., City of Chicago v.

Beretta U.S.A. Corp., 821 N.E.2d 1099, 1114-16 (Ill.

2004) (“[W]e do not intend to minimize the very real

problem of violent crime and the difficult tasks facing law enforcement and other public officials,” but

liability law does not allow a cause of action “so

broad and undefined that the presence of any potentially dangerous instrumentality in the community

could be deemed to” invoke it.). But some succeeded.

See City of Cincinnati v. Beretta U.S.A. Corp., 768

N.E.2d 1136, 1141 (Ohio 2002). Congress stated in

the PLCAA that it enacted this law to ensure these

companies would not be held liable for “harm caused

by those who criminally or unlawfully misuse” their

products. 15 U.S.C. § 7901(a)(5).

In deciding this case, therefore, the Court should

clarify that the principles of proximate causation are

12

not malleable and do not become more permissive

when governments bring the suits. Proximate causation, including in government recoupment litigation,

must continue to distinguish (a) tortious acts that

directly cause harm from (b) manufacturing, selling

and promoting lawful products that someone else uses or misuses to cause harm. The Court should hold

that foreseeability that risks associated with lawful

products may materialize does not establish proximate cause against manufacturers or sellers of those

products when such harms occur, including in lawsuits brought by governments over money spent to

address societal issues associated with these hams.

II. THIS CASE IS EMBLEMATIC OF NUMEROUS LAWSUITS SEEKING TO IMPOSE

INDUSTRY-WIDE LIABILITY FOR COSTS

ASSOCIATED WITH MANUFACTURING

AND SELLING LAWFUL PRODUCTS

The proximate causation concerns this litigation

raises are not unique to this case. Over the past

three decades, manufacturers and sellers across several industries have been sued to pay costs associated with unlawful uses of lawful products. These lawsuits generally attempt to subject individual companies, or entire industries, to liability for societal

harms associated with lawful products they sold.

Many of these lawsuits have sought to require businesses, rather than individual wrongdoers or taxpayers, to remediate environmental damage or pay

costs of social harms associated with categories of

products, regardless of proximate causation. They

typically assert that a non-defective product had

negative societal impacts, notwithstanding its benefits, and that manufacturers should pay “their fair

13

share” of the attendant costs. See generally Victor E.

Schwartz et al., Can Governments Impose a New Tort

Duty to Prevent External Risks? The “No Fault” Theories Behind Today’s High-Stakes Government Recoupment Suits, 44 Wake Forest L. Rev. 923 (2009).

Most courts have properly rejected these lawsuits,

including on proximate causation grounds. As discussed, around the time the PLCAA was enacted,

several governments were seeking to impose costs

related to lead poisoning and lead paint remediation

on companies that lawfully manufactured lead paint

and pigment decades earlier—rather than on landlords responsible for maintaining properties with

lead paint. See, e.g., Rhode Island v. Lead Indus.

Ass’n, Inc., 951 A.2d 428 (R.I. 2008); In re Lead Paint

Litig., 924 A.2d 484, 505 (N.J. 2007). The Rhode Island Supreme Court, which was the first state high

court to rule in that litigation, affirmed that proximate causation is “a basic requirement” and that

governments cannot take causation shortcuts unavailable to individual plaintiffs. Lead Indus. Ass’n,

951 A.2d at 450. “In addition to proving that defendant is the cause-in-fact of an injury, a plaintiff must

demonstrate proximate cause.” Id. Echoed the New

Jersey Supreme Court: “basic fairness dictates that a

defendant must have caused the [harm] to be held

liable” for it. In re Lead Paint Litig., 924 A.2d at 451.

Another series of claims involved governments suing pharmaceutical manufacturers, distributors and

pharmacies over costs associated with prescription

opioid abuse. See, e.g. Rachel Graf, Ky. AG Hires

Motley Rice, Others in Opioid Fight, Law360, Sept.

14

22, 2017.2 Several years earlier, individuals brought

personal injury claims against opioid manufacturers,

but courts concluded that prescription drug abuse

was largely caused by physicians who overprescribed

the painkillers and individuals who took the drugs

illegally. See Max Mitchell, Can Opiate Litigation

Ever Be the New Mass Tort?, Legal Intelligencer,

Mar. 31, 2017.3 In reframing the litigation, government plaintiffs blamed manufacturers, distributors

and pharmacies for generating a marketplace in

which opioid addiction could arise. See id. The lawsuits sought money for fighting opioid addiction and,

in some cases, heroin addiction as well. See, e.g.,

West Virginia v. McKesson Corp., No. 16-cv-01772,

2016 WL 843443 (S.D. W. Va. Feb. 23, 2016). The

Oklahoma Supreme Court, which is the only state

high court to rule on this litigation so far, dismissed

the claims, in part on causation grounds. See State ex

rel. Hunter v. Johnson & Johnson, 499 P.3d 719

(Okla. 2021). The court observed that this lawsuit

“challenges us to rethink traditional notions of liability and causation” because manufacturers do not

control how wholesalers distributed their products,

how others dispersed their products, or how individuals used their products. See id. at 728-29.

The burgeoning litigation over climate change has

followed this same playbook. See, e.g., City & Cnty. of

Honolulu v. Sunoco LP, 537 P.3d 1173, 1184 (Haw.

2023), petition for cert. pending (Nos. 23-947, 232 https://www.law360.com/articles/966930/ky-ag-hires-motley-

rice-others-in-opioid-fight.

3 http://www.law.com/thelegalintelligencer/almID/

1202782732124.

15

952). More than thirty state and local governments

have sued energy producers for costs related to climate change, including paying for seawalls and other

infrastructure projects allegedly needed to abate the

impacts of the changing climate. See Manufacturers’

Accountability Project, Manufacturers’ Center for

Legal Action (providing detailed background on this

litigation).4 The Second Circuit, which is the only

court to reach the merits of the cases, underscored

the litigation’s causation problems. See City of New

York v. Chevron Corp., 993 F.3d 81, 86 (2d Cir. 2021).

It noted the City’s “ambitious” goal was “to effectively impose strict liability for the damages caused by

fossil fuel emissions no matter where in the world

those emissions were released (or who released

them).” Id. at 93. Yet some state courts, as indicated

by the climate litigation petitions pending in front of

this Court, have looked past these fundamental causation issues. See Nos. 23-947, 23-952.

Overall, many states apply “what appears to be

an absolute rule”: if a product after being sold, creates or contributes to a harm, including a public nuisance, the manufacturer or seller is not liable unless

it “controls or directs” the criminal or tortious activity causing that harm. SUEZ Water N.Y. Inc. v. E.I.

du Pont de Nemours & Co., 578 F. Supp. 3d 511, 546

(S.D.N.Y. 2022). The Third Restatement of Torts recently affirmed that public nuisance liability, in particular, has been rejected in such product cases “because the common law of public nuisance is an inapt

vehicle for addressing the conduct at issue. Mass

harms caused by dangerous products are better addressed through products liability, which has been

16

developed and refined with sensitivity to the various

policies at stake.” Restatement (Third) of Torts: Liability for Economic Harm § 8 cmt. g (2020).

In order to avoid this jurisprudence, government

plaintiffs in these litigations, as here, are effectively

asking courts to lower proximate causation standards for them. They are attempting to avoid traditional notions of proximate causation by creating a

Cuisinart of industry-wide liability, where all manufacturers are blended together so they do not have to

show that any specific defendant proximately caused

any specific harm. They generally seek to replace

proximate causation with risk contribution theories,

suggesting the chain of commerce is a viable substitute for the chain of causation, or imposing market

share or other types of enterprise liability.

As the Missouri Supreme Court stated in rejecting such a proposition: “To the extent the city’s argument is that the Restatement requires something

less than proof of actual causation or should replace

actual causation in a [government] case, it is incorrect.” City of St. Louis v. Benjamin Moore & Co., 226

S.W.3d 110, 114 (Mo. 2007). Otherwise, as other

courts have noted, people would frame a case as a

government action “rather than a product liability

suit” in order to lower causation standards. See City

of Chicago v. Am. Cyanamid Co., No. 02 CH 16212,

2003 WL 23315567, at *4 (Ill. Cir. Ct. Oct. 7, 2003).

The Court should clarify here that imposing jointand-several liability against entire industries or basing liability on market-share or risk contribution is

not a substitute for proximate causation. Again, in

litigation brought by private plaintiffs, courts have

widely rejected theories of collective liability when

17

plaintiffs cannot establish that a particular product

caused their injuries. These rulings have occurred in

the context of litigation over asbestos,5 silicone

breast implants6 and high-fructose corn syrup,7

among other products.8 Courts have rejected attempts to impose liability on manufacturers of

brand-name medicines when a plaintiff used a generic drug made by another company.9 And, a court has

determined that quick-serve restaurants do not proximately cause obesity and other health problems.

Pelman, 237 F. Supp. 2d at 538 (“No reasonable per5 See, e.g., Case v. Fibreboard Corp., 743 P.2d 1062, 1067 (Okla.

1987) (“[P]ublic policy favoring recovery on the part of an innocent plaintiff does not justify the abrogation of the rights of a

potential defendant to have a causative link proven . . . where

there is a significant probability that those acts were related to

the injury.”); Bostic v. Ga. Pac. Corp., 439 S.W.3d 332, 340 (Tex.

2014) (reaffirming Texas’s rejection of “theories of collective liability—alternative liability, concert of action, enterprise liability, and market share liability”).

6 See Matter of N.Y. State Silicone Breast Implant Litig., 166

Misc.2d 85, 89-90 (N.Y. Sup. Ct. 1995).

7 See S.F. v Archer Daniels Midland Co., 594 Fed. App’x 11, 13

(2d Cir. 2014) (rejecting market share liability against five

manufacturers of high-fructose corn syrup, which plaintiffs alleged was a toxic substance that caused diabetes).

8 See City of St. Louis, 226 S.W.3d at 116 (“[E]ven if it could

prove that because of that defendant’s market share there was

a statistical probability that its paint was in a certain percentage of the properties at issue — that would not establish that

the particular defendant actually caused the problem”).

9 See, e.g., In re Darvocet, Darvon, & Propoxyphene Prods. Liab.

Litig., 756 F.3d 917, 938-39, 941-54 (6th Cir. 2014) (applying

laws of 22 states); McNair v. Johnson & Johnson, 818 S.E.2d

son could find probable cause based on the facts in

the Complaint without resorting to wild speculation.”) (cleaned up). The same tenets of proximate

cause must apply in government litigation as well.

The California courts provided a cautionary tale

in its lead paint litigation, where a Court of Appeal

allowed local governments to circumvent proximate

causation. See People v. ConAgra Grocery Prods. Co.,

17 Cal. App. 5th 51 (2017), cert. denied, 138 S. Ct.

377 (2018). The court eliminated the bedrock principle that a person can be liable only for harms that he

or she caused, holding that plaintiffs need not “identify the specific location” of any home with lead paint

or “a specific product sold by each such Defendant.”

People v. Atl. Richfield Co., No. 100CV788657, 2014

WL 1385823, at *44 (Cal. Super. Ct. Mar. 26, 2014).

Rather, three manufacturers were held jointly and

severally liable for remediating all lead paint regardless of who sold which lead paint, when, or where. It

was of no consequence that the overwhelming majority of the lead paint to be abated was sold by competitors, often years after a defendant stopped selling

lead paint. This ruling was a watershed moment

leading to the recent mass proliferation of government recoupment litigation. Although some lawsuits

have led to trial court victories and settlements, the

causation theories have not been widely validated by

state or federal courts. See Philip S. Goldberg, Is Today’s Attempt at a Public Nuisance “Super Tort” The

Emperor’s New Clothes of Modern Litigation?, 31

Mealey’s Emerging Toxic Torts 15 (Nov. 1, 2022).

Most courts have properly recognized that removing proximate causation from tort law would create

litigation chaos, “giv[ing] rise to a cause of action . . .

19

regardless of the defendant’s degree of culpability.”

Tioga Pub. Sch. Dist. v. U.S. Gypsum Co., 984 F.2d

915, 921 (8th Cir. 1993). “All a creative mind would

need to do is construct a scenario describing a known

or perceived harm of a sort that can somehow be said

to relate back to the way a company or an industry

makes, markets, and/or sells its non-defective, lawful

product or service, and a [case] would be conceived

and a lawsuit born.” Spitzer v. Sturm, Ruger & Co.,

309 A.D.2d 91, 96 (N.Y. App. Div. 2003).

If the Court allows this case to proceed under

such a watered-down view of proximate cause, the

targets for this type of litigation would be endless.

Companies that make watches terrorists use as components in bombs would be sued by victims of those

terrorist attacks, regardless of whether the companies had any connection to the unlawful acts.10 Same

for companies whose software and other products are

misused to defraud people,11 whose ski masks are

used to conceal faces of those who commit crimes,12

10 See, e.g., David Brunnstrom, Debris from North Korean Mis-

sile in Ukraine Could Expose Procurement Networks, Reuters,

Feb. 24, 2024 (reporting a North Korean missile fired by Russia

in Ukraine contained a large number of components linked to

U.S.-based companies); Denise Winterman, Casio F-91W: The

and whose knives are used in robberies and homicides.13 The list would go on and on.

In each of these situations, manufacturers are

making and selling lawful products. They, like others, may be aware that, in the aggregate, some of the

products they sell lawfully will be diverted, used or

misused, sometimes criminally, in ways that cause

harm. The Court should reaffirm traditional notions

of proximate causation to ward off these litigations.

III. MANAGING PUBLIC RISKS ASSOCIATED

WITH INHERENTLY HARMFUL PRODUCTS SHOULD REMAIN A REGULATORY,

NOT LITIGATION MATTER

Finally, in ruling in this case, the Court should

ensure that no government—foreign or domestic—

can use the civil justice system to regulate lawful

products by imposing untenable liability costs on the

production and sale of those products. These government plaintiffs often appreciate that the effect of

“holding producers liable for all the harm their products proximately cause”—not that the producers

proximately cause—is effectively prohibiting “altogether the continued commercial distribution of such

products.” See James A. Henderson, Jr. & Aaron D.

Twerski, Closing the American Products Liability

Frontier: The Rejection of Liability Without Defect, 66

N.Y.U. L. Rev. 1266, 1329 (1991) (emphasis added);

21

see also City of New York, 993 F.3d at 93 (“If the Producers want to avoid all liability, then their only solution would be to cease global production altogether.”).

Often, regulation through litigation, in addition to

seeking financial relief, is a goal of these actions. See,

e.g., Establishing Accountability for Climate Damages: Lessons from Tobacco Control, Summary of the

Workshop on Climate Accountability, Public Opinion,

and Legal Strategies, Union of Concerned Scientists

& Climate Accountability Inst. (Oct. 2012) (“Even if

your ultimate goal might be to shut down a company,

you still might be wise to start out by asking for

compensation for injured parties.”).14 Here, Respondent is seeking an injunction to directly regulate Petitioners’ business. See Pet. at 12. Some may consider

Respondents’ proposed reforms sensible, but it is not

the role of the courts to impose these changes.

Some scholars have argued that proximate causation in cases like this one should be relaxed to provide a remedy whenever they perceive that the regulatory process has failed to address a public welfare

issue. See, e.g., David A. Dana, Public Nuisance Law

When Politics Fails, 83 Ohio St. L.J. 61 (2022). They

believe courts should be open to regulating through

litigation “notwithstanding the democratic legitimacy and technological competence objections.” Id. at

66. They also acknowledge that this view casts aside

notions of wrongdoing and proximate causation. See

Leslie Kendrick, The Perils and Promise of Public

Nuisance, 132 Yale L.J. 702, 759 (2023) (acknowledging this view is a “problem for those who think tort is

exclusively the province of wrongful conduct”). They

believe liability against manufacturers and sellers

allow the impact of a public welfare issue to be

spread among all users of a product, akin to a tax. Id.

at 770. The result, though, would be a “Rorschach

blot” for causation, where courts can impose liability

without established principles. Thomas W. Merrill,

The New Public Nuisance: Illegitimate and Dysfunctional, 132 Yale L.J. Forum 985, 988 (2023).

Allowing such lawsuits would give local, state and

foreign officials unbridled power to determine which

alleged social ills manufacturers and sellers of products would be “taxed” through litigation to solve. As

courts in other contexts have held, “it might be

tempting to wink at this whole thing and add pressure on parties who are presumed to have lots of

money. . . . But it’s bad law.” City of New Haven v.

Purdue Pharma, L.P., 2019 WL 423990, at *8 (Conn.

Super. Ct., Jan. 8, 2019). The Supreme Court of Iowa

explained that making a party who is not at-fault

pay for the alleged damages is “[d]eep pocket jurisprudence [which] is law without principle.” Huck v.

Wyeth, Inc., 850 N.W.2d 353, 380 (Iowa 2014) (internal quotation omitted).

Ensuring liability law properly aligns with and

does not undermine statutory or regulatory authority

is a significant concern for amici and their members

because manufacturers of all types of products with

inherent risks—from prescription medicines to

household chemicals to energy products to alcoholic

beverages—must be able to rely on government regulations seeking to balance consumer and public risks.

23

Weighing costs, benefits and social value of producing and using these products and factoring in any

adverse effects is part of the delicate balancing for

which only legislatures and administrative agencies,

pursuant to legislative authority, are suited. If a

company violates any such regulation, there are enforcement remedies tailored to that violation.

Here, the Court should prevent the circumvention

of the PLCAA, and reinforce the traditional notions

of proximate causation in cases such as this one. Addressing societal costs associated with product use or

misuse does not justify altering longstanding regulatory and liability law, including proximate causation.

CONCLUSION

For these reasons, amici curiae respectfully request that this Court reverse the ruling below.
