There is no single historic gas price lawsuit against Donald Trump, but the legal reality may be even more significant. An unprecedented wave of litigation is crashing over the administration from multiple directions simultaneously — the Supreme Court has already struck down his tariff authority in a landmark 6-3 ruling, more than 2,000 companies are suing for refunds on $133 billion in invalidated tariffs, coalitions of state attorneys general are challenging his replacement tariffs, and consumer class actions are now targeting retailers who profited from the tariff regime. All of this is unfolding against a backdrop of gas prices that have surged roughly 20 percent in two weeks, climbing from $2.98 to $3.58 per gallon nationally after the U.S. launched military operations against Iran. The question of whether Trump could face a gas price lawsuit specifically misses the broader picture.
The legal exposure is not limited to fuel costs — it extends across the entire consumer economy. A Yale Lab study estimated that tariffs cost the average American household about $1,000 per year, while a separate Yale analysis found the average family lost $1,751 last year from tariff-related price increases. With Brent crude spiking to nearly $120 per barrel and roughly 20 percent of global oil supply disrupted in the first nine days of the Iran conflict, the economic pain is compounding from multiple policy decisions at once. We will examine what these lawsuits mean for ordinary consumers, whether gas prices could trigger additional legal action, and what options people have for recovering money lost to policies that courts have already deemed illegal.

What Legal Challenges Could Trump Face Over Gas Prices and Tariffs?
The most consequential legal blow landed on February 20, 2026, when the Supreme Court ruled 6-3 that Trump had overstepped his authority by using the 1977 International Emergency Economic Powers Act to impose sweeping tariffs. The IEEPA was designed to give presidents tools to address genuine national security emergencies — sanctions, asset freezes, trade restrictions during wartime — not to restructure trade policy unilaterally. The Court’s majority found that Trump had stretched the statute well beyond its intended scope, effectively legislating from the Oval Office on matters that belong to Congress. Before the ruling came down, $133 billion in tariffs had already been collected under IEEPA authority, and more than 2,000 companies have since filed suit seeking refunds on those payments. What makes this situation historically unusual is the speed and breadth of the legal response. Within weeks of the Supreme Court decision, Trump pivoted to a new legal justification — Section 122 of the Trade Act of 1974 — to impose fresh 10 percent tariffs.
No president has ever used Section 122 for tariff purposes before, and legal scholars immediately flagged the move as vulnerable to the same kind of constitutional challenge. New York Attorney General Letitia James assembled a coalition of 21 attorneys general along with the governors of Kentucky and Pennsylvania to sue over the replacement tariffs. California and 23 additional states filed their own separate challenge on March 5. Compare this to previous trade disputes, where legal challenges typically involved a handful of industry groups — the current litigation involves nearly every state in the country and thousands of individual companies. The gas price dimension adds another layer entirely. While no lawsuit has been filed specifically alleging that Trump caused gas prices to rise, the Iran conflict — which disrupted 20 percent of global oil supply, more than double the previous record set during the 1956-57 Suez Crisis — has created economic conditions that may intensify existing claims. When consumers argue in court that tariffs cost them thousands of dollars per year, the concurrent gas price spike strengthens the narrative that administration policies have imposed tangible financial harm on ordinary Americans.
How the Supreme Court Tariff Ruling Changed the Legal Landscape
The February 2026 Supreme Court decision did something rare in American law — it invalidated a sitting president’s trade policy on constitutional grounds while the policy was actively generating revenue. The 6-3 ruling was not a narrow technical finding; it was a clear statement that IEEPA does not grant the president authority to impose tariffs. The practical consequence is that $133 billion in collected tariffs now sits in a legal gray zone, with the government potentially on the hook to return that money to the companies that paid it. However, winning a refund is not as straightforward as it might sound. Companies that passed tariff costs along to consumers — which is most of them — face complicated questions about who is actually owed the money. If a manufacturer paid a 25 percent tariff on imported steel, raised prices to cover the cost, and consumers absorbed the increase, it is not obvious that the manufacturer suffered the economic harm.
This is precisely the argument at the center of the Costco class action filed on March 11 in Illinois federal court, where customers are demanding that the retailer pass along any tariff refunds it receives rather than pocketing the windfall. A similar case has been filed against FedEx in Florida. These consumer suits represent a second front of litigation that the companies suing for refunds probably did not anticipate — they may recover billions from the government only to face claims from their own customers. The legal uncertainty is compounded by Trump’s decision to immediately impose new tariffs under Section 122 after the Supreme Court struck down the IEEPA tariffs. This move essentially dares the courts to strike him down a second time, and the multi-state attorney general coalitions are doing exactly that. If Section 122 tariffs are also invalidated, the administration will have lost two consecutive constitutional challenges on trade authority in a matter of months — a scenario without precedent in modern American governance.
Why Gas Prices Are Surging and Who Bears Legal Responsibility
The national average gas price hit $3.58 per gallon by mid-March 2026, a jump of roughly 60 cents from the pre-war price of $2.98. The immediate cause is the Iran conflict, which disrupted an extraordinary 20 percent of global oil supply in its first nine days. Brent crude spiked to nearly $120 per barrel — a price level that, if sustained, could push the national average past $4 per gallon. The Energy Information Administration forecasts that Brent crude will remain above $95 per barrel for at least the next two months before potentially easing to $80 in summer and $70 by fall. Trump dismissed the price surge as “a little glitch” of the Iran war, a characterization that drew sharp criticism. California Governor Gavin Newsom blasted the administration on March 10 for “raising gasoline prices on Americans with no plan and no accountability.” The administration has responded with executive actions — ordering the release of oil from the Strategic Petroleum Reserve and considering Jones Act waivers that would allow foreign-flagged ships to transport fuel between U.S. ports, a move that would lower domestic shipping costs but faces opposition from the American maritime industry.
The legal question of responsibility for gas prices is genuinely complicated. Presidents do not set gasoline prices, and courts have historically been reluctant to hold the executive branch liable for market outcomes that result from foreign policy decisions. A war-driven oil shock is materially different from a tariff, which is a deliberate policy choice to raise the cost of specific goods. That distinction matters legally. The tariff lawsuits have a clear theory of harm — the president exceeded his statutory authority, collected money he was not entitled to collect, and consumers paid higher prices as a direct result. A gas price lawsuit would need to argue that the decision to go to war with Iran was itself unlawful or that the administration failed to take reasonable steps to mitigate foreseeable economic harm. That is a much harder case to make in court.
Consumer Class Actions — What Options Do Affected Consumers Have?
For consumers looking to recover money lost to tariff-inflated prices, the class action lawsuits against major retailers may offer the most direct path. The Costco case filed in Illinois federal court and the FedEx case in Florida both argue that these companies collected higher prices from consumers to cover tariff costs and should be required to pass along refunds now that those tariffs have been invalidated. If these cases succeed, they could establish a template for similar suits against virtually any retailer or service provider that raised prices citing tariffs. The tradeoff for consumers is between individual action and class participation. In a class action, the attorneys handle the litigation and affected consumers typically receive a share of any settlement or judgment without needing to prove their individual losses. The downside is that individual payouts in consumer class actions are often modest — sometimes a few dollars per person — even when the total settlement is large.
Companies like Costco have millions of customers, and spreading a refund across that base can dilute the per-person recovery significantly. By contrast, businesses that paid tariffs directly and can document the exact amounts stand to recover much more, which is why more than 2,000 companies have already filed individual refund claims. For gas prices specifically, there is currently no class action mechanism available. Gas prices are set by market forces — supply, demand, refining capacity, transportation costs — and individual purchasing decisions are nearly impossible to aggregate into a class claim. Consumers who want to mitigate the impact of rising gas prices are limited to practical steps: reducing driving, shopping for the lowest local prices, and monitoring the EIA’s forecasts for indications of when prices might decline. The EIA’s current projection suggests meaningful relief may not arrive until summer or fall 2026.
The Risks of Untested Legal Theories and Unprecedented Tariff Strategies
The Trump administration’s pivot to Section 122 of the Trade Act of 1974 deserves close attention because it represents genuinely uncharted legal territory. No president has ever used Section 122 to impose tariffs, and the provision was designed to address balance-of-payments emergencies — a narrow economic condition that requires specific findings about the health of international dollar reserves. Legal experts across the political spectrum have questioned whether current economic conditions meet that threshold, and the multi-state lawsuits are challenging the administration to prove it. The danger for consumers is that legal uncertainty can drag on for years. The IEEPA tariff case moved relatively quickly because the legal question was straightforward — does IEEPA authorize tariffs? The Supreme Court said no. Section 122 presents murkier questions about executive discretion, economic findings, and the scope of delegated trade authority. If the new tariffs survive initial legal challenges, consumers could face years of elevated prices while appeals work through the courts.
And even if the tariffs are eventually struck down, recovering money already spent on inflated goods is far more difficult than preventing future overcharges. There is also a compounding risk that is easy to overlook. The Iran war and the tariff disputes are not separate economic events — they interact. Tariffs raise the cost of imported goods, including components used in energy infrastructure. Higher energy prices raise transportation and manufacturing costs across the supply chain. When PBS reported that Trump’s “roaring economy” narrative had met a rough start to 2026 with job losses, rising gas prices, and uncertainty, the analysis reflected an economy being squeezed from multiple directions simultaneously. Consumers who are paying more at the pump and more at the store are absorbing the cumulative impact of several policy decisions at once.
How State Attorneys General Are Leading the Legal Fight
The coalition-building among state attorneys general has been one of the more striking features of the current legal landscape. New York AG Letitia James organized a group of 21 attorneys general plus the governors of Kentucky and Pennsylvania — notably, a bipartisan coalition — to challenge the Section 122 tariffs. California’s separate lawsuit, joined by 23 other states, covers similar legal ground but reflects a strategic decision to file in a different jurisdiction, increasing the odds that at least one federal circuit will issue a favorable ruling.
This approach mirrors the strategy that state AGs used during the first Trump administration to challenge travel bans and environmental deregulation, but the scale is larger. When nearly every state in the country is suing the federal government over the same policy, it signals a level of legal consensus that courts tend to take seriously. For consumers, state AG lawsuits are often more impactful than private class actions because they can seek injunctive relief — court orders that actually stop the challenged policy — rather than just monetary damages after the fact.
What Comes Next for Gas Prices, Tariffs, and Consumer Litigation
The next several months will be defined by two variables: whether the Iran conflict escalates or de-escalates, and how quickly courts rule on the Section 122 tariff challenges. The EIA’s forecast of Brent crude falling to $80 per barrel by summer assumes some stabilization in the Middle East — an assumption that could prove optimistic. If oil prices remain elevated and tariffs survive legal challenge, the Yale estimate of $1,000 to $1,751 in annual household losses could climb higher.
On the legal front, the consumer class actions against Costco and FedEx will be closely watched as potential models. If courts certify these classes and allow consumer claims to proceed alongside corporate refund lawsuits, it could open the door to a much broader wave of consumer litigation. The combination of the Supreme Court’s clear ruling that IEEPA tariffs were illegal, the questionable legal foundation of the replacement tariffs, and the mounting economic pressure from gas prices creates conditions where consumer protection law may evolve rapidly. Whether that evolution delivers meaningful relief to ordinary Americans or gets bogged down in procedural battles will depend largely on decisions made in the next few months.
Frequently Asked Questions
Is there a specific lawsuit I can join over high gas prices?
No. As of March 2026, there is no class action lawsuit specifically targeting gas prices. Gas prices are driven by global oil markets, and courts generally do not hold presidents liable for market-driven price changes, even when policy decisions like the Iran war contribute to supply disruptions.
How do I get a refund on tariffs I paid through higher retail prices?
Consumer class actions have been filed against companies like Costco and FedEx seeking to force those retailers to pass along tariff refunds to customers. If these cases proceed and result in settlements, affected consumers would typically be notified and given an opportunity to file claims. No action is needed right now other than keeping receipts and monitoring case developments.
Did the Supreme Court actually rule Trump’s tariffs illegal?
Yes. On February 20, 2026, the Supreme Court ruled 6-3 that Trump exceeded his authority by using the International Emergency Economic Powers Act to impose tariffs. The IEEPA was not designed to grant tariff authority, and $133 billion in tariffs collected under that statute have been invalidated.
Are the new Section 122 tariffs also likely to be struck down?
That remains uncertain. No president has ever used Section 122 of the Trade Act of 1974 to impose tariffs, and multiple lawsuits from state attorney general coalitions are challenging the legal basis for these tariffs. However, the legal questions surrounding Section 122 are more complex than the IEEPA case, and resolution could take months or longer.
When will gas prices come back down?
The Energy Information Administration forecasts that Brent crude oil will remain above $95 per barrel for the next two months, potentially falling to $80 by summer and $70 by fall 2026. However, these projections depend on the trajectory of the Iran conflict and could shift significantly if the situation escalates.
