Yes, the Trump administration is already facing multiple court battles that directly affect what Americans pay for fuel. As of March 2026, lawsuits are flying in both directions. The Department of Justice sued California on March 12, 2026, over the state’s vehicle emission rules, arguing they drive up car and fuel costs for consumers nationwide. Meanwhile, California and 23 other states have sued the Trump administration over tariff policies that have contributed to rising consumer costs, including fuel.
The legal fights are playing out against a backdrop of gas prices that have surged roughly 60 cents per gallon in just two weeks, with the national average hitting $3.63 as of March 13, 2026, according to AAA. These court battles are not abstract policy disputes. They hit drivers at the pump. The Trump administration claims its rollback of California’s emission standards will save consumers $109 billion over five years and roughly $1,000 per new vehicle. Critics, including California Governor Gavin Newsom, fired back on March 10, 2026, accusing Trump of “raising gasoline prices on Americans with no plan and no accountability.”

What Court Battles Could Trump Face Over Rising Fuel Costs?
The most significant legal action came on March 12, 2026, when the DOJ and the U.S. Transportation Department filed a federal lawsuit against the California Air Resources Board in the U.S. District Court for the Eastern District of California. The suit targets two California policies: the state’s zero-emission vehicle mandate and its tailpipe greenhouse gas rules. The administration argues these regulations are preempted by federal Corporate Average fuel Economy standards established under the Energy Policy and Conservation Act of 1975. In plain terms, the federal government is saying California does not have the legal authority to set its own fuel economy rules, and that doing so illegally forces automakers to sell electric vehicles, which raises costs for everyone. This lawsuit is part of what the administration branded the “Freedom Means Affordable Cars” initiative.
California’s rules required roughly 22 percent of cars sold by any automaker in the state to be zero-emission by 2025. Because California is the largest auto market in the country, its rules effectively set the standard for manufacturers nationwide. The trump administration had already blocked California’s plan to ban new gas-powered car sales by 2035 during the summer of 2025, so this lawsuit represents an escalation of a fight that has been building for years. On the other side, the lawsuits against Trump are just as aggressive. California and 23 other states filed suit challenging the administration’s tariff policies. The New York Attorney General led a separate lawsuit targeting what she called the administration’s “latest illegal tariffs.” These tariffs have had downstream effects on fuel costs, since they increase the price of imported goods, equipment, and materials used across the energy supply chain. For consumers, the result is a legal tug-of-war where both sides claim to be fighting for lower prices.

How Tariff Rulings Have Already Changed the Fuel Cost Equation
The Supreme Court delivered a major blow to the Trump administration’s tariff strategy on February 21, 2026, ruling that tariff power belongs to Congress, not the president. That decision effectively eliminated roughly half of the approximately $30 billion per month the federal government had been collecting in tariffs. The ruling was significant not just for trade policy but for consumer prices broadly, including fuel and energy costs that had been inflated by tariff-driven supply chain pressures. However, the legal battle over tariffs is far from settled. As of March 12, 2026, states were seeking a fast-track ruling on Trump’s 10 percent global tariff in a case reported by Bloomberg.
If the courts strike down additional tariffs, consumers could see some relief. But there is an important limitation here: even if tariffs are rolled back, fuel prices are driven by global crude oil markets, refining capacity, and geopolitical events that no single court ruling can control. The U.S.-Israel-Iran conflict, for example, is currently the primary driver of the gas price spike, and no tariff ruling will change that dynamic. The practical takeaway for consumers is that tariff rulings create a floor, not a ceiling, for fuel prices. Removing tariffs can prevent additional cost increases, but they cannot offset price surges caused by international conflicts or supply disruptions. Anyone expecting a court ruling to bring gas prices down to pre-2026 levels is likely to be disappointed.
What Gas Prices Look Like Right Now and Where They Could Go
The numbers tell a stark story. The national average gas price stood at $3.63 per gallon as of March 13, 2026, according to AAA. That figure represents a surge of approximately 60 cents, or more than 20 percent, in just two weeks. The primary cause is the U.S.-Israel-Iran conflict, which has driven up crude oil prices globally. California leads the nation at $5.34 per gallon, while Kansas sits at the low end at $3.01. Analysts have warned that gas prices could set a new all-time high by the end of March 2026.
That would surpass the previous record of $5.02 per gallon set in June 2022. For context, this potential record would arrive at a time when the administration is simultaneously fighting in court to lower vehicle costs and facing accusations that its own policies have contributed to higher energy prices. The disconnect between the administration’s rhetoric about affordable energy and the reality at the pump has become a focal point for critics. For drivers in states like California, where prices already exceed $5 per gallon, the combination of state-level fuel taxes, stricter emissions requirements, and global crude price increases creates a compounding effect. A court victory for the Trump administration against California’s emission rules would not lower gas prices in the short term. Those rules primarily affect vehicle manufacturing standards, not the price of gasoline itself.

What Consumers Should Track as These Lawsuits Play Out
There are two separate cost concerns consumers should distinguish between. First, vehicle purchase costs: the Trump administration’s lawsuit against California’s emission rules is fundamentally about whether automakers will be forced to sell more electric vehicles, which the administration argues raises the average price of new cars. If the administration wins, the $1,000 per vehicle savings it projects would apply to future car purchases, not to fuel prices at the pump. Second, fuel costs at the pump: these are driven primarily by crude oil prices, refining costs, state taxes, and federal tariff policies. The tariff lawsuits have more direct relevance here.
The Supreme Court’s February ruling already removed a significant chunk of tariff-related costs, but additional litigation is ongoing. Consumers should watch for rulings on the remaining tariffs, particularly the 10 percent global tariff that states are challenging. The tradeoff is worth understanding clearly. Stricter emission standards tend to increase upfront vehicle costs but reduce long-term fuel spending, since more efficient cars use less gas. Rolling back those standards may lower the sticker price of a new car but does nothing to protect buyers from volatile fuel prices. Consumers who plan to keep a vehicle for many years may actually pay more overall if fuel economy standards are weakened and gas prices remain elevated.
Trump’s Unfulfilled Energy Promise and the Accountability Gap
President Trump promised to cut energy bills in half. One year into his term, NPR reported in January 2026 that he has not delivered on that promise. This matters for the legal landscape because broken promises create political pressure, which generates more lawsuits and regulatory challenges. Governor Newsom’s March 10, 2026, statement accusing Trump of raising gasoline prices with “no plan and no accountability” was not just political theater. It was a preview of the arguments states will make in court. The limitation consumers should be aware of is that presidents have far less control over gas prices than campaign rhetoric suggests.
Global crude oil markets, OPEC production decisions, and geopolitical conflicts are the primary drivers. A president can influence prices at the margins through tariff policy, strategic petroleum reserve releases, and regulatory changes, but no administration can unilaterally cut energy costs in half when crude oil prices are spiking due to a Middle Eastern conflict. Lawsuits can address specific policy failures, but they cannot override market fundamentals. The accountability gap is real, though. When an administration makes specific, measurable promises about energy costs and then pursues tariff policies that courts have found illegal, consumers have legitimate grounds to question whether the government’s actions align with its stated goals. That tension is what fuels the ongoing litigation from both state attorneys general and advocacy groups.

The Jones Act Waiver and Its Potential Impact on Fuel Costs
One lesser-known policy lever under consideration is a suspension of the Jones Act. On March 12, 2026, reports indicated that Trump was considering waiving this 1920 law, which requires goods shipped between U.S. ports to travel on American-built, American-owned, and American-crewed vessels. The Jones Act significantly increases the cost of shipping fuel between U.S.
Ports, particularly to markets like Hawaii, Puerto Rico, and the Northeast. Suspending the Jones Act could reduce fuel transportation costs by allowing cheaper foreign-flagged vessels to carry oil and gasoline between domestic ports. For example, shipping fuel from Gulf Coast refineries to the Northeast is substantially more expensive under the Jones Act than it would be using foreign carriers. However, the waiver faces opposition from the domestic shipping industry and maritime unions, and any suspension would likely be temporary and limited in scope. It is not a long-term fix for high fuel prices, but it could provide modest relief during a price crisis.
What Comes Next in the Legal Fight Over Fuel Costs
The coming months will be decisive. The federal lawsuit against California’s emission rules will take time to work through the courts, and California is expected to mount an aggressive defense. Meanwhile, the fast-track tariff case could produce a ruling relatively quickly, with immediate implications for consumer costs. If gas prices do set a new all-time high by the end of March 2026, political and legal pressure on the administration will intensify. For consumers, the most important thing to understand is that these court battles are interconnected.
A ruling on emission standards affects vehicle costs. A ruling on tariffs affects the price of goods across the economy, including fuel. And global events like the U.S.-Israel-Iran conflict can overwhelm any domestic policy change. The legal system can address specific government overreach, but it cannot insulate Americans from the reality of a volatile global energy market. What courts can do is hold the government accountable for policies that make an already difficult situation worse.
Frequently Asked Questions
Can a president directly control gas prices?
Not directly. Presidents can influence fuel costs through tariff policy, regulation, and strategic petroleum reserve management, but global crude oil markets and geopolitical events are the primary drivers of gas prices. No single policy change can override these market forces.
What did the Supreme Court rule about tariffs in February 2026?
On February 21, 2026, the Supreme Court ruled that tariff power belongs to Congress, not the president. This decision eliminated roughly half of the approximately $30 billion per month the federal government had been collecting in tariffs, providing some consumer cost relief.
How would the lawsuit against California’s emission rules affect fuel prices?
The lawsuit primarily targets vehicle manufacturing standards, not gas prices directly. If the administration wins, it could lower the sticker price of new cars by reducing the percentage of electric vehicles automakers must sell. However, it would not reduce the price of gasoline at the pump.
Why are gas prices rising so fast in March 2026?
Gas prices surged approximately 60 cents per gallon in two weeks, driven primarily by the U.S.-Israel-Iran conflict, which pushed up global crude oil prices. The national average reached $3.63 per gallon as of March 13, 2026, with California topping $5.34.
What is the Jones Act and how does it affect fuel costs?
The Jones Act is a 1920 law requiring goods shipped between U.S. ports to use American-built, American-owned, and American-crewed vessels. This increases domestic fuel shipping costs. Trump considered suspending it on March 12, 2026, which could modestly reduce fuel transportation expenses.
