Nintendo Sues Trump Administration, Seeking Tariff Refunds With Interest, A Full Legal Breakdown

Nintendo of America has filed a federal lawsuit against the Trump administration, demanding a prompt refund — with interest — of all tariff payments the company made under executive orders that the U.S. Supreme Court later ruled unconstitutional. Filed on March 6, 2026, in the U.S. Court of International Trade, the lawsuit marks the latest escalation in one of the most consequential corporate legal battles in recent American trade history.

This article breaks down exactly what Nintendo is suing for, the legal basis of its claim, how the Supreme Court ruling paved the way for the case, and what the outcome could mean for the broader landscape of Trump tariff refund litigation.

What Is Nintendo’s Lawsuit About?

At its core, Nintendo’s lawsuit is a demand for the return of money it paid in tariffs that a court has since declared illegal. The company argues it has been ‘substantially harmed by the unlawful execution and imposition of unauthorized Executive Orders’ and the fees it paid to import products — primarily gaming hardware like the Nintendo Switch 2 and its accessories — into the United States.

“All tariffs collected under the IEEPA Duties must be refunded with interest,” Nintendo’s lawyers wrote in the complaint filed with the U.S. Court of International Trade.

The lawsuit targets multiple federal agencies and senior officials, including:

• U.S. Treasury Department and Treasury Secretary Scott Bessent
• U.S. Department of Homeland Security and former Secretary Kristi Noem
• U.S. Department of Commerce and Secretary Howard Lutnick
• U.S. Customs and Border Protection (CBP) and Commissioner Rodney Scott
• Office of the U.S. Trade Representative and Jamieson Greer

Nintendo is asking the court to order that all IEEPA tariff payments it made since February 2025 be refunded promptly and with interest, and that it be reimbursed for legal costs. The company explicitly states in its filing that without a court order in its specific case, there is no guarantee it will ever recover the money owed, even in the wake of the Supreme Court’s decision.

The Supreme Court Ruling That Made This Lawsuit Possible

To understand why Nintendo’s lawsuit has a strong legal foundation, it is essential to understand what the Supreme Court decided just weeks earlier in Learning Resources, Inc. v. Trump.

Learning Resources, Inc. v. Trump (February 20, 2026)

In a landmark 6-3 ruling, the U.S. Supreme Court held that the International Emergency Economic Powers Act of 1977 (IEEPA) does not authorize the president to unilaterally impose tariffs on imports. Chief Justice John Roberts authored the majority opinion, joined by Justices Sotomayor, Kagan, Gorsuch, Barrett, and Jackson.

The majority concluded plainly: IEEPA does not give the president the power to set tariffs — a power that belongs constitutionally to Congress. The court struck down the sweeping global tariffs Trump had imposed beginning in February 2025, including the so-called ‘Liberation Day’ tariffs announced on April 2, 2025, which targeted nearly every U.S. trading partner with rates ranging from 10% for many nations to 24% for Japan and 46% for Vietnam.

Notably, two of the three justices appointed by Trump himself — Neil Gorsuch and Amy Coney Barrett — joined the majority. Both raised concerns during oral arguments about whether allowing such broad presidential tariff authority would create a ‘one-way ratchet’ of Congressional power flowing permanently to the executive branch.

The ruling invalidated Trump’s tariff regime but did not specifically address refunds — it left that question to lower courts. That gap is precisely why Nintendo and more than 2,000 other companies have since rushed to file their own lawsuits before the U.S. Court of International Trade.

Timeline: How Trump’s Tariff Campaign Led to This Lawsuit

Understanding the legal context requires a look at how rapidly the tariff situation evolved over the fourteen months leading up to Nintendo’s filing.

February 1, 2025

President Trump issues the first executive orders under IEEPA, imposing tariffs on Canada, Mexico, and China, citing fentanyl trafficking and illegal immigration as national emergencies.

April 2, 2025 — ‘Liberation Day’

Trump announces sweeping global tariffs on nearly all U.S. trading partners. Japan faces a 24% reciprocal tariff; Vietnam, where many Nintendo products are manufactured, faces a 46% tariff. Nintendo pauses U.S. preorders for the Nintendo Switch 2.

April–May 2025

Tariffs escalate to over 125% on Chinese goods before being reduced to 34% in May. Companies and states begin filing legal challenges from day one.

May 2025

The U.S. Court of International Trade (CIT) rules that Trump lacked authority under IEEPA to impose these tariffs, permanently enjoining their enforcement. The ruling is stayed pending appeal.

August 2025

The Federal Circuit Court of Appeals upholds the CIT ruling en banc. The stay is extended while Trump appeals to the Supreme Court.

November 5, 2025

The Supreme Court hears oral arguments in the consolidated case. Court observers note justices across the ideological spectrum express deep skepticism of the government’s position.

February 20, 2026

The Supreme Court issues its 6-3 ruling in Learning Resources, Inc. v. Trump, striking down the IEEPA tariffs as unconstitutional.

February 23, 2026

FedEx files the first major corporate lawsuit post-ruling, seeking a full refund of all IEEPA tariffs paid.

March 2, 2026

The Federal Circuit Court of Appeals rejects the Trump administration’s request to delay litigation and repayment, clearing the path for the CIT to proceed.

March 4, 2026

Judge Richard K. Eaton of the CIT rules that all importers who paid IEEPA tariffs are legally entitled to refunds, with interest. He announces he will personally oversee all IEEPA refund cases.

March 5, 2026

U.S. Customs and Border Protection tells the court it collected approximately $166 billion in IEEPA tariffs — but cannot comply with the refund order due to technical limitations. CBP says a new refund system could be ready in 45 days.

March 6, 2026

Nintendo of America files its lawsuit in the U.S. Court of International Trade, demanding a prompt refund with interest of all IEEPA tariffs paid.

How the Tariffs Hit Nintendo: The Switch 2 Story

Nintendo’s legal battle is inseparable from the story of the Nintendo Switch 2 launch — one of the most eagerly anticipated console releases in recent gaming history that was directly and publicly disrupted by Trump’s tariff policy.

When Liberation Day tariffs were announced in April 2025, Nintendo of America was forced to pause U.S. preorders for the Switch 2, explicitly attributing the decision to tariffs and ‘evolving market conditions.’ While the company ultimately kept the console’s base price at its originally advertised level, it raised prices on accessories, citing the tariff burden.

Many of Nintendo’s products are manufactured not in Japan but in Vietnam and China — two of the countries most aggressively targeted by Trump’s tariff policy. Vietnam faced a 46% reciprocal tariff under IEEPA, and Chinese goods faced tariffs that at their peak exceeded 125%. This meant Nintendo was absorbing massive duty costs on the vast majority of its physical product imports into the United States throughout 2025.

Nintendo’s lawsuit argues that the company will ‘suffer imminent and irreparable harm’ for the tariff payments it made if the court does not order the government to return those funds with interest. The total amount Nintendo is owed has not been publicly disclosed in the court filing, though analysts have noted that given the scale of Switch 2 hardware imports, the figure is likely substantial.

Nintendo Tariff Lawsuit: Key Facts at a Glance

The Legal Argument: Why Nintendo Says It Is Owed a Refund With Interest

Nintendo’s legal argument rests on several reinforcing pillars, each rooted in established U.S. trade and constitutional law.

1. The IEEPA Tariffs Were Unconstitutional From the Start

Nintendo’s complaint states that the tariffs were never lawful — not when they were first imposed and not at any point during their collection. The Supreme Court’s ruling confirmed what multiple lower courts had already found: that IEEPA does not give the president authority to set tariffs, which is a power the Constitution assigns to Congress. Since the duties were illegal ab initio, the argument goes, the government has no rightful claim to the money it collected.

2. Judge Eaton’s March 4 Ruling Establishes Entitlement to Refunds

Days before Nintendo filed its complaint, U.S. Court of International Trade Judge Richard Eaton issued a ruling in the Atmus Filtration case stating that all importers who paid IEEPA tariffs are ‘entitled to benefit’ from the Supreme Court decision and are therefore legally owed refunds with interest. This ruling gave Nintendo and similarly situated companies a clear legal green light — and a compelling reason to file their own cases rather than wait for a government-initiated refund process that may never come.

3. Filing Is Necessary to Preserve Refund Rights

Nintendo’s lawyers are explicit on this point in the complaint: without a court order in its specific case, Nintendo is ‘not guaranteed the refund to which it is entitled.’ Legal scholars and trade attorneys have noted that the CIT previously ruled that IEEPA duty collection is not a CBP decision subject to standard administrative protest — it can only be challenged through a timely lawsuit in the CIT. In other words, companies that don’t sue may lose their right to a refund entirely.

4. The Government Has Already Conceded the Refund Obligation

Nintendo’s lawyers note that the U.S. government itself has ‘conceded this point’ in other court filings — acknowledging that if the IEEPA tariffs were struck down, refunds would be required. Despite this concession, the administration has done nothing to proactively issue refunds, and CBP has told the court it currently lacks the technical capability to process them. This inaction, Nintendo argues, makes judicial relief not just appropriate but necessary.

The $166 Billion Problem: Why the Government Can’t Just Write Checks

One of the most remarkable aspects of this unfolding legal crisis is the practical impossibility of the refund process at its current scale. When Judge Eaton ordered CBP to begin issuing refunds, the agency responded bluntly: it cannot comply.

In a court filing submitted on March 6, 2026, Brandon Lord, executive director of CBP’s trade policy and programs directorate, disclosed that the agency has collected approximately $166 billion in IEEPA tariffs — paid by more than 330,000 importers — and that its existing systems were ‘not designed for a mass refund’ of this magnitude. CBP proposed that a new refund processing system could be ready in approximately 45 days.

Trade lawyer Alexis Early, a partner at Bryan Cave Leighton Paisner, stated that CBP’s refund system ‘routinely refunds tariffs in cases of error, but it was not designed for a mass refund’ of this scale. The sheer volume of claims — with some estimates of $175 billion in total exposure — is effectively unprecedented in the history of U.S. trade administration.

Meanwhile, the Court of International Trade suspended the immediate compliance portion of Judge Eaton’s March 5 order while the logistics of the refund process are worked out. The Trump administration had separately asked the Federal Circuit for a 90-day delay to allow ‘the political branches an opportunity to consider options’ — a request the court denied.

Justice Department lawyers have warned that even with cooperation from all parties, the refund process could take years to fully resolve. This is why Nintendo and other companies argue that individual court orders in their specific cases are not just helpful but essential — the only way to guarantee they actually receive their money.

Nintendo Is Not Alone: The Broader Wave of Trump Tariff Refund Litigation

Nintendo’s lawsuit is one of thousands. According to Bloomberg, by the end of February 2026 — just ten days after the Supreme Court ruling — over 2,000 lawsuits had already been filed in the U.S. Court of International Trade by companies seeking IEEPA tariff refunds. That number has continued to grow daily.

Major companies that have filed or are reportedly seeking tariff refunds include:

• FedEx — one of the first major companies to file after the Supreme Court ruling, expecting $1 billion in annual tariff-related losses
• Costco — the retail giant joining a growing coalition of major retailers seeking refunds
• Dyson, Revlon, Bausch & Lomb, L’Oreal, EssilorLuxottica — consumer goods companies
• Goodyear, GoPro, Toyota — spanning automotive and consumer tech sectors
• A coalition of 24 state attorneys general — who filed collectively to seek refunds and challenge Trump’s new tariff measures

Judge Eaton has stated he will personally oversee all IEEPA refund cases filed in the Court of International Trade — a notable consolidation of judicial authority signaling the court’s intent to handle this wave of litigation in a coordinated, systematic way.

Trump’s Response: New Tariffs Under a Different Legal Theory

Stripped of the IEEPA tool, the Trump administration has not abandoned its tariff agenda. Following the Supreme Court ruling, the president announced plans to impose new tariffs using Section 122 of the Trade Act of 1974 — a statutory provision that grants emergency tariff authority for a limited period of approximately 150 days. Trump announced a new 15% global tariff under this authority.

The critical legal distinction is that Section 122 authority cannot retroactively justify the IEEPA tariffs already collected — meaning it does nothing to resolve Nintendo’s claims or those of the thousands of other companies already seeking refunds. It also raises fresh legal questions, since Section 122 tariffs come with their own statutory limitations that the administration will need to navigate.

Trump’s public reaction to the Supreme Court ruling was defiant. ‘Their decision is incorrect. But it doesn’t matter, because we have very powerful alternatives,’ the president told reporters. Two dozen state attorneys general have already sued over the newly announced Section 122 tariffs.

Frequently Asked Questions: Nintendo vs. Trump Administration Tariff Lawsuit

Why is Nintendo suing the Trump administration over tariffs?

Nintendo is suing to recover tariff payments it made on U.S. imports since February 2025 under executive orders that the Supreme Court later ruled unconstitutional. Because the government has not proactively issued refunds and CBP has said it cannot process them immediately, Nintendo argues a court order in its specific case is necessary to guarantee repayment with interest.

What is the IEEPA and why were the tariffs ruled illegal?

The International Emergency Economic Powers Act of 1977 (IEEPA) is a federal law that gives the president expanded authority over international economic transactions during declared national emergencies. The Supreme Court ruled 6-3 in February 2026 that IEEPA does not give the president the power to impose tariffs, because the authority to set tariffs is a power the Constitution assigns to Congress, not the executive branch.

How much money is Nintendo seeking to recover from tariff refunds?

Nintendo has not publicly disclosed the exact amount it claims to be owed. However, given that a large portion of its hardware — including Nintendo Switch 2 units and accessories — is manufactured in Vietnam (which faced a 46% tariff) and China (which faced tariffs exceeding 125%), trade analysts expect the figure to run into hundreds of millions of dollars.

Who is the judge overseeing Trump tariff refund cases?

Judge Richard K. Eaton of the U.S. Court of International Trade has declared that he will personally oversee all IEEPA tariff refund cases. On March 4, 2026, he ruled that all importers who paid IEEPA tariffs are legally entitled to refunds with interest, following the Supreme Court’s decision in Learning Resources, Inc. v. Trump.

Can Nintendo really get its tariff money back with interest?

Based on current judicial rulings, yes. Both Judge Eaton’s March 4 ruling and the Supreme Court’s February 20 decision support Nintendo’s legal position. The practical challenge is timing — CBP has said it lacks the systems to process mass refunds immediately and estimates it will need 45 days to build a new refund processing system. The court has temporarily suspended the immediate compliance order while that infrastructure is built.

What other companies are suing for Trump tariff refunds?

As of early March 2026, over 2,000 companies have filed lawsuits in the U.S. Court of International Trade seeking IEEPA tariff refunds. Notable filers include FedEx, Costco, Dyson, Revlon, Bausch & Lomb, L’Oreal, Goodyear, GoPro, and Toyota. A coalition of 24 state attorneys general has also filed suit.

Why didn’t the Supreme Court just order refunds itself?

The Supreme Court’s ruling in Learning Resources, Inc. v. Trump addressed only the constitutional validity of the tariffs — it did not specifically order refunds or outline a refund process. The court noted that the U.S. Court of International Trade has exclusive jurisdiction over these claims, effectively directing companies that want refunds to file individual cases in that court, which is exactly what Nintendo and thousands of other importers have done.

How did Nintendo’s tariff lawsuit affect the Nintendo Switch 2 launch?

When the Liberation Day tariffs were announced in April 2025, Nintendo directly attributed its pause of U.S. Switch 2 preorders to the tariff situation. While the company ultimately maintained the base console price, it raised prices on Switch 2 accessories due to the tariff burden. Nintendo’s lawsuit argues these costs represent ‘imminent and irreparable harm’ that entitles the company to both a refund and interest on the money unlawfully collected.

What to Watch: Key Legal Developments Ahead

The Nintendo lawsuit is one data point in a rapidly evolving legal landscape. Here are the key developments to monitor in the coming weeks and months:

• CBP’s 45-day refund system development — whether the agency actually delivers a functional mass-refund mechanism on schedule, and whether the court accepts it as compliant with the refund order.
• The Trump administration’s appeal strategy — the DOJ is expected to seek additional stays or appeal Judge Eaton’s March 4 ruling. Any successful delay could push refunds back by months or years.
• Legal challenges to the new Section 122 tariffs — the 24 state attorneys general suits may result in a second wave of tariff invalidations, potentially creating yet another layer of refund litigation.
• Congressional action — with IEEPA no longer a viable tariff tool, lawmakers face pressure to either grant the president new statutory tariff authority or assert Congressional control over trade policy more aggressively.
• Industry pricing responses — if Nintendo and other tech companies successfully recover tariff refunds, the critical question is whether they will pass savings back to consumers through lower prices, or retain the margin.

Conclusion: A Landmark Moment in U.S. Corporate Trade Litigation

Nintendo’s decision to sue the Trump administration for tariff refunds with interest is not an isolated act of corporate defiance — it is part of a coordinated legal reckoning that is reshaping the boundaries of executive trade power in the United States.

The Supreme Court has ruled. A federal trade judge has ordered refunds. More than 2,000 companies have filed claims. And yet the government says it currently cannot pay. That tension — between clear legal obligation and administrative inability — is the central drama that courts, companies, and consumers will be watching unfold throughout 2026.

For Nintendo, the stakes go beyond legal principle. The company absorbed real costs on real products — hardware that millions of consumers in the United States purchased and use. Getting that money back, with interest, would be both a legal vindication and a material financial recovery from what the nation’s highest court has now confirmed was an unconstitutional exercise of executive power.
