Yes, the abuse of war powers is already fueling consumer lawsuits over inflated prices, and gas is squarely in the crosshairs. The Supreme Court’s February 2026 ruling in *Learning Resources, Inc. v. Trump* struck down tariffs imposed under the International Emergency Economic Powers Act, finding that the president had overstepped Congress’s exclusive taxing authority. That decision cracked open the floodgates.
At least five consumer class actions have been filed in federal courts across Florida, Georgia, South Carolina, and Tennessee seeking refunds from retailers and shippers who passed unlawful tariff costs onto buyers. Meanwhile, a separate but related crisis is compounding the damage: U.S.-Israeli military strikes on Iran that began February 28, 2026 have driven crude oil past $110 per barrel, pushing average gas prices above $3.50 nationally and past $5.20 in parts of California. The connection between executive overreach and your wallet is no longer theoretical. Goldman Sachs estimates that American consumers bore the majority of a $175 billion tariff bill, costing the average household roughly $1,500 in 2026 alone. Now layer on a wartime oil shock that has boosted energy stocks by 26 percent while the broader market declined, and the question shifts from whether lawsuits will come to how many.

How Did War Powers Abuse Create the Legal Basis for Consumer Lawsuits Over Gas Prices?
The story begins with IEEPA, a 1977 law that gives the president broad authority to regulate economic transactions during declared national emergencies. The trump administration used IEEPA to impose sweeping tariffs on imports, bypassing the usual congressional process. The Supreme Court shut that down definitively, holding that tariff power is “a branch of the taxing power” reserved for Congress under Article I of the Constitution. The Court of International Trade followed up on March 4, 2026, ordering U.S. Customs and Border Protection to begin issuing refunds on more than $130 billion collected under the unlawful tariffs. But here is the critical distinction that drives the lawsuits: the government collected tariffs from importers, and importers passed those costs to consumers through higher retail prices.
The refunds flow back to the importers, not to the people who actually paid the inflated prices at checkout. That gap is exactly what plaintiffs’ attorneys are targeting. A Costco member named Matthew Stockov filed suit in Illinois demanding that the retailer share its tariff refunds with customers who paid inflated prices during the period the illegal tariffs were in effect. The legal theory is straightforward: if the tariffs were unlawful, and companies raised prices to cover them, consumers are entitled to a share of whatever money comes back. The Federal Reserve Bank of New York found that nearly 90 percent of tariff costs were borne by American firms and consumers, not by foreign exporters. That statistic is central to the plaintiffs’ case. If companies absorbed almost none of the cost on the way up, the argument goes, they should not pocket all of the refund on the way down.
What the Iran Conflict Means for Gas Prices and Consumer Pocketbooks
The Iran war added a second shock on top of the tariff damage. Following the U.S.-Israeli strikes that began on February 28, 2026, crude oil surged roughly 42 percent from pre-war levels near $67 per barrel to above $110. The national average for gasoline climbed to between $3.48 and $3.58 per gallon, a 17 to 20 percent increase in barely two weeks. Diesel hit $4.65 per gallon, up 23 percent, which Patrick De Haan of GasBuddy called “a massive jolt” to logistics and agriculture. In California, some stations were charging between $5.20 and $6.50 per gallon by mid-March. The Strait of Hormuz, the narrow waterway at the center of the conflict zone, handles roughly 20 percent of the world’s crude oil and liquefied natural gas.
Any sustained disruption there sends shockwaves through global energy markets almost instantly. Gregory Daco, chief economist at EY-Parthenon, warned that “the longer this lasts, the more significant the shock would be.” However, higher gas prices alone do not automatically create legal liability. Wartime price increases driven by genuine supply disruption are painful but generally lawful. The lawsuits gain traction only when companies exploit the crisis to pad margins beyond what supply conditions justify, or when the government action that triggered the price spike was itself illegal. That is an important limitation. Consumers frustrated by $5 gas cannot simply sue their local station. They need evidence of either unlawful government policy, corporate price-fixing, or deceptive billing practices.
The Class Actions Already Filed Against Major Companies
The post-ruling litigation is moving fast. Beyond the Costco case, EssilorLuxottica, the parent company of Ray-Ban, was sued for raising retail prices as de facto “tariff surcharges” that consumers had no way to identify or contest. FedEx and UPS face claims for billing customers itemized IEEPA tariff fees, charges that were based on a tariff the Supreme Court has now declared illegal. According to analysis from Arnold & Porter, these cases are concentrated in the Southeast, with filings in Florida, Georgia, South Carolina, and Tennessee federal courts. The legal theories vary.
Some plaintiffs argue unjust enrichment, claiming that retailers collected money under false pretenses and should disgorge the excess. Others pursue breach of contract claims, particularly against membership-based retailers like Costco, where the implicit bargain is that members get fair pricing. The FedEx and UPS cases focus on billing transparency, arguing that itemizing an unlawful government fee on an invoice and collecting it from customers creates direct liability when that fee is later invalidated. Meanwhile, 24 state attorneys general, led by California and New York, sued the Trump administration over its attempt to impose replacement tariffs under Section 122 of the Trade Act, a provision that allows temporary tariffs for balance-of-payments emergencies but has never been used for broad protectionist purposes. The states argue this is just another attempt to do through the back door what the Supreme Court closed through the front.
Oil Company Profiteering and What Regulators Are Doing About It
The gas price lawsuits operate on a parallel track that predates the Iran conflict. A consolidated federal lawsuit targets 18 oil companies, accusing them of conspiring to limit shale oil production to artificially inflate fuel prices. The case draws on evidence uncovered by the FTC, which found that Scott Sheffield, former CEO of Pioneer Natural Resources, used WhatsApp to coordinate production limits with OPEC members. If proven, this would transform garden-variety price complaints into antitrust claims with treble damages. The profiteering numbers are stark.
Energy firms in the S&P 500 are collectively up 26 percent in 2026, while the broader index has declined 1.5 percent. That divergence alone does not prove wrongdoing, since oil companies naturally benefit from higher crude prices. But the combination of documented collusion evidence, wartime supply disruption, and record sector gains creates a powerful narrative for plaintiffs. On the regulatory side, California passed a 2023 law designed to cap refinery profit margins, but enforcement was delayed until 2029. With gas now topping $5 per gallon across much of the state, that delay is drawing intense scrutiny. The tradeoff is real: aggressive price caps could discourage refinery investment and tighten supply further, but delayed enforcement means consumers have no protection during the exact crisis the law was designed to address.
Why Getting Money Back Will Be Harder Than Filing the Lawsuit
The biggest obstacle for consumer plaintiffs is proving damages with enough specificity to satisfy a federal court. Tariff refunds flow to the importer of record, which is typically a wholesaler or manufacturer, not the retailer and certainly not the end consumer. Tracing the tariff cost through multiple layers of distribution, markup, and retail pricing to show exactly how much each consumer overpaid is an enormous forensic accounting challenge. Class certification presents its own hurdles. Courts require that common questions of law and fact predominate over individual ones.
A consumer who bought a $200 pair of Ray-Bans may have a very different damages calculation than one who paid $15 in itemized FedEx surcharges. If the court concludes that individual damage calculations overwhelm the common legal questions, certification could be denied, and without a class, most individual claims are too small to justify litigation. There is also a timing issue. Companies that received tariff refunds from CBP have strong incentives to characterize those refunds as general corporate revenue rather than customer-owed funds. The longer the gap between the refund and any court order to distribute it, the harder it becomes to segregate and trace the money. Plaintiffs’ lawyers are pushing for expedited discovery precisely because delay favors defendants.
How State Attorney General Actions Could Provide a Faster Path to Relief
For most consumers, the 24-state attorney general coalition may offer more practical relief than private class actions. State AG suits carry the weight of government enforcement, have access to civil investigative demands that move faster than private discovery, and can result in restitution funds that distribute money to affected residents without requiring individual proof of purchase.
When New York and California jointly lead an enforcement action, they bring resources and legal infrastructure that private plaintiffs’ firms simply cannot match. The AG suits also target the government itself rather than private companies, which sidesteps many of the tracing and certification problems that plague the consumer class actions. If the courts rule that Section 122 replacement tariffs are also unlawful, the resulting refund orders would flow through the same CBP mechanism already established for IEEPA refunds, creating a more direct pipeline for consumer recovery.
What Comes Next for Consumers Caught Between War, Tariffs, and High Gas Prices
The convergence of unlawful tariffs, a wartime oil shock, and documented industry collusion is historically unusual and legally untested at this scale. The IEEPA ruling established that executive overreach has financial consequences that courts are willing to unwind. The Iran conflict and oil company profiteering lawsuits may extend that principle into energy markets if plaintiffs can connect the dots between government action, corporate behavior, and consumer harm.
Looking ahead, the most likely outcome is a patchwork of settlements. Retailers facing tariff refund claims will calculate whether it is cheaper to share a portion of their CBP refunds than to litigate for years. Oil companies facing antitrust exposure may seek to settle the 18-company collusion case before trial, particularly given the FTC’s WhatsApp evidence against Sheffield. For consumers, the practical advice is to save receipts, monitor settlement databases, and pay attention to state AG announcements, because the money that eventually flows back will go to those who can document what they paid.
Frequently Asked Questions
Can I sue my local gas station for high gas prices during the Iran conflict?
Generally no. Local gas stations set prices based on wholesale costs, and wartime supply disruptions are a legitimate market factor. Lawsuits require evidence of illegal government action, price-fixing, or deceptive billing, not simply high prices driven by global events.
How do I get a refund from the IEEPA tariffs the Supreme Court struck down?
Tariff refunds are being issued by CBP to importers of record, not directly to consumers. However, pending class actions against retailers like Costco argue that companies receiving refunds should share them with customers who paid inflated prices. Monitor these cases for settlement opportunities.
What is the Costco tariff refund lawsuit about?
Member Matthew Stockov sued Costco in Illinois, arguing that since the Supreme Court declared IEEPA tariffs unconstitutional and Costco will receive refunds from CBP, the company should pass those savings back to members who paid higher prices during the tariff period.
How much did IEEPA tariffs cost the average household?
The Tax Foundation estimated that IEEPA tariffs cost the average American household approximately $1,500 in 2026. The Federal Reserve Bank of New York found that nearly 90 percent of tariff costs were passed through to American firms and consumers.
Are oil companies being sued for price gouging during the Iran war?
A consolidated federal lawsuit targets 18 oil companies for allegedly conspiring to limit shale production and inflate prices, based partly on FTC evidence that Pioneer Natural Resources’ former CEO coordinated with OPEC via WhatsApp. This predates the Iran conflict but has gained urgency as energy stocks surged 26 percent in 2026.
Will California’s refinery profit cap law help with current gas prices?
Not immediately. While California passed a law in 2023 to cap refinery profit margins, enforcement was delayed until 2029. With gas exceeding $5 per gallon in parts of the state, the delayed implementation is under growing political scrutiny but offers no near-term consumer relief.
