Yes, war can and already has triggered consumer lawsuits, though the legal path from armed conflict to courtroom is rarely direct. The more common trigger is the economic fallout that wars produce: tariffs imposed under emergency powers, supply chain disruptions that send prices soaring, and companies that exploit crisis conditions to pad their margins. In the most striking recent example, the U.S.
Supreme Court’s February 2026 ruling striking down IEEPA tariffs has unleashed a wave of consumer class action lawsuits against major retailers and brands, with shoppers demanding refunds for price increases they say were illegally passed along to them. The connection between war and consumer litigation runs deeper than most people realize. From trade wars that weaponize tariffs to actual armed conflicts that create monopoly conditions for certain companies, the legal theories are diverse and evolving.

How Do Trade Wars and Armed Conflicts Lead to Consumer Lawsuits?
Wars affect consumer prices through several mechanisms, each of which can create legal exposure for companies. Trade wars introduce tariffs that raise the cost of imported goods. Armed conflicts disrupt supply chains, creating scarcity that drives up prices. And in some cases, companies use the fog of crisis as cover to raise prices beyond what the actual cost increases justify. Each of these scenarios can give rise to different legal claims, from unjust enrichment to price gouging to violations of consumer protection statutes. The current wave of tariff-related class actions illustrates the trade war pathway clearly. When the Trump administration imposed sweeping tariffs under the International Emergency Economic Powers Act, companies across industries raised their prices.
After the Supreme Court ruled 6-3 on February 20, 2026 that IEEPA does not authorize the president to impose tariffs without clear congressional authorization, consumers began filing suits arguing they deserve refunds for those price increases. At least five putative consumer class actions were filed in federal courts across Florida, Georgia, South Carolina, and Tennessee within weeks of the ruling. Armed conflicts create a different but equally potent litigation trigger. When Israel’s war with Hamas began in October 2023, most foreign airlines stopped flying to Israel. El Al, as the dominant remaining carrier, raised its fares significantly. The Israel Competition Authority hit El Al with a proposed fine of NIS 121 million (approximately $39 million), alleging the airline charged “excessive and unfair” fares during the war. A separate class action lawsuit accused the airline of wartime price gouging by exploiting its sudden monopoly status.
The Tariff Refund Lawsuits Reshaping Consumer Rights
The Supreme Court’s IEEPA decision has created what may be the largest consumer refund dispute in recent history. With more than $170 billion in IEEPA-related tariffs collected, the potential refund pool is enormous. On March 4, 2026, Judge Richard K. Eaton of the U.S. Court of International Trade directed U.S. Customs and Border Protection to refund the IEEPA tariffs, stating that all importers of record are entitled to refunds. However, CBP told the court just two days later that its systems are not currently equipped to process refunds and would need approximately 45 days to implement a workable mechanism.
Here is where consumers face a critical limitation: the refunds are legally owed to importers of record, not to the end consumers who paid the higher prices. Companies like Costco, FedEx, and EssilorLuxottica collected tariff-inflated prices from shoppers, but the formal refund process channels money back to the businesses that paid the tariffs at the border. This gap between who paid the economic cost and who receives the legal refund is exactly what the new consumer class actions are trying to bridge. However, legal experts warn that these consumer cases face steep odds. To succeed, plaintiffs must prove that a specific company raised its prices because of tariffs, and by a quantifiable amount. Unless a company publicly stated it increased a product’s price by a specific dollar figure due to tariffs, establishing that causal link in court will be difficult. Companies routinely adjust prices for dozens of reasons, and isolating the tariff component requires evidence that most consumers simply do not have.
Real Lawsuits Consumers Have Already Filed
Several specific cases illustrate how consumers are attempting to hold companies accountable for war- and tariff-driven price increases. Nathan Ward filed a class action complaint against EssilorLuxottica in the Eastern District of New York on February 26, 2026. Ward alleged that the company passed IEEPA tariff costs directly to consumers. His evidence was specific: the price of Ray-Ban RB8313 carbon fibre sunglasses held steady between September 2024 and March 2025 but increased from $287 to $304 between March and May 2025, a period that coincided precisely with the tariff implementation.
Matthew Stockov, an Illinois resident, filed a proposed class action against Costco, alleging the big-box retailer raised prices as a direct result of the tariffs and should now return those overcharges to its members. The Costco case is particularly interesting because membership warehouse clubs market themselves on low prices, making it arguably easier to show that tariff-driven increases contradicted the company’s core value proposition to consumers. In Miami, FedEx customer Matthew Resier filed a proposed class action against the shipping company, alleging FedEx acted as a “customs broker” and collected $36 in import taxes and fees on a pair of shoes he ordered from Germany. Resier’s theory is distinct from the retail cases: he argues FedEx should not have collected tariff-related charges that were later ruled unconstitutional. Together, these cases represent at least three different legal theories for how consumers can seek recovery from war- and tariff-related overcharges.
What Consumers Need to Prove and Why It Is Difficult
Consumer plaintiffs in tariff and war-related class actions must clear several legal hurdles that corporate plaintiffs do not face. The first and most significant is causation. A company seeking a tariff refund from CBP simply shows it paid the tariff. A consumer suing a retailer must show that the retailer raised a specific product’s price by a specific amount because of the tariff, and that the consumer personally paid that inflated price. This is a fundamentally harder evidentiary burden. The second challenge is the legal theory itself. Most state consumer protection statutes were not written with tariff pass-throughs in mind.
Plaintiffs are relying on theories like unjust enrichment, which requires showing that the company was unjustly enriched at the consumer’s expense. But companies will argue that passing along increased costs is normal business practice, not unjust conduct. The tradeoff for consumers is this: joining a class action costs nothing upfront and preserves the possibility of recovery, but the realistic odds of a meaningful individual payout are low, especially if the class is defined broadly. By contrast, companies that filed their own tariff refund lawsuits face a much cleaner path. More than 1,000 companies have filed suits seeking refunds of tariffs they paid directly to CBP. Their claims are straightforward: the tariffs were unconstitutional, we paid them, give the money back. Consumers watching these corporate refunds flow may feel entitled to their share, but the legal system does not currently provide a clean mechanism for that downstream recovery.
Price Gouging Laws and Their Wartime Limitations
Price gouging statutes are the most obvious legal tool for consumers harmed by war-driven price increases, but these laws have significant gaps. Most state price gouging laws only activate during a declared state of emergency, and they typically apply to essential goods like food, fuel, and medical supplies. A trade war or overseas armed conflict may not trigger the emergency declarations that activate these statutes, leaving consumers without the legal framework they assume exists. Even where price gouging laws do apply, consumers often lack a private right of action, meaning they cannot sue on their own behalf. Instead, enforcement falls to state attorneys general, who must choose which cases to pursue with limited resources.
In July 2025, Representative Josh Riley introduced the Cracking Down on Price Gouging Act, which would strengthen the Defense Production Act of 1950 and create the first national ban on price gouging during emergencies. If enacted, it would give consumers broader protections, but as of early 2026, no federal price gouging statute with a private right of action exists. The absence of a uniform federal standard means outcomes depend heavily on geography. A consumer in a state with strong consumer protection laws and an aggressive attorney general may see enforcement action. A consumer in a state with weak or narrow price gouging statutes may have no recourse at all, even if they paid identical price increases for the same products.
How the Defense Production Act Connects War to Consumer Markets
The Defense Production Act of 1950 gives the federal government sweeping power to redirect supply chains during national emergencies, and its use can directly affect consumer prices. When Russia’s war in Ukraine disrupted global supplies of metals, energy, and munitions, the U.S. government invoked DPA authorities to increase domestic arms production.
Any business that touches a critical supply chain, even tangentially, can become subject to DPA prioritization, meaning government orders jump to the front of the line and civilian orders get delayed or cancelled. For consumers, DPA activation can mean sudden shortages and price spikes in products that depend on the same raw materials or manufacturing capacity that the government has commandeered. Companies caught in this squeeze face breach-of-contract risks with their commercial customers and potential consumer complaints about unfulfilled orders or inflated prices. While the DPA itself does not create a direct cause of action for consumers, the downstream effects of its use can fuel the unjust enrichment and consumer protection claims that class action attorneys are already pursuing.
What Comes Next for War-Related Consumer Litigation
The current wave of tariff class actions is likely just the beginning. As geopolitical instability continues to reshape global trade, the intersection of war, executive power, and consumer prices will generate new legal theories and new litigation. The Supreme Court’s IEEPA ruling established a critical precedent: emergency powers have limits, and economic actions taken under those powers can be reversed.
Future administrations that impose tariffs or trade restrictions under emergency authority will face immediate legal challenges, and the consumer class action bar is now primed to follow those challenges with downstream suits. The bigger question is whether Congress will close the gap between corporate tariff refunds and consumer recovery. Legislation creating a private right of action for consumers harmed by unconstitutional tariffs, or a federal price gouging statute that applies during trade wars and armed conflicts, would fundamentally change the landscape. Until then, consumers will continue to rely on creative class action theories and the uncertain prospect of unjust enrichment claims to seek their share of war-driven overcharges.
Frequently Asked Questions
Can I get a refund for higher prices I paid during the tariff period?
Possibly, but it will be difficult. The Supreme Court’s February 2026 ruling struck down IEEPA tariffs, and refunds of approximately $175 billion are owed, but those refunds go to importers of record, not directly to consumers. Consumer class actions are attempting to bridge this gap, but legal experts say proving a specific price increase was caused by tariffs is a high evidentiary bar.
Do price gouging laws protect me during a trade war?
In most states, no. Price gouging statutes typically require a declared state of emergency and apply to essential goods. A trade war or overseas conflict may not trigger these protections. There is currently no federal price gouging law with a private right of action, though legislation has been proposed.
Should I join a class action lawsuit over tariff-related price increases?
If you are eligible, there is generally no cost to joining a class action. The downside risk is minimal. However, individual payouts in consumer class actions tend to be small, and these tariff cases face significant legal obstacles. Keep receipts and documentation of price changes in case a relevant class action is certified.
What is the difference between a company’s tariff refund and a consumer’s tariff refund?
Companies that paid tariffs directly to U.S. Customs and Border Protection can file for refunds through the Court of International Trade. Consumers who paid higher retail prices have no direct refund mechanism and must instead sue the company that charged them, arguing theories like unjust enrichment. The legal paths are fundamentally different.
Has anyone successfully sued over wartime price gouging?
Yes. In Israel, El Al faced a proposed fine of approximately $39 million from the Competition Authority for charging excessive fares after most foreign airlines stopped flying to Israel during the Hamas conflict. A class action was also filed against the airline. In the U.S., state attorneys general have won price gouging cases during declared emergencies, though wartime-specific consumer victories are rare.
