On February 20, 2026, the United States Supreme Court delivered a 6-3 verdict that effectively dismantled the economic cornerstone of the current administration. The court ruled that the President had no authority to bypass Congress to impose sweeping, universal tariffs under the International Emergency Economic Powers Act (IEEPA). Within hours, the man who architected this legal ambush, Neal Katyal, was already moving to the next phase of the siege.
This was not a simple case of a lawyer winning a high-stakes argument. It was a structural reclamation of the Constitution’s Taxing Clause. Katyal, a former Acting Solicitor General and current partner at Milbank, convinced a majority of the justices—including two appointed by Donald Trump—that a president cannot rebrand a tax as an "emergency regulation" to avoid the messy process of legislative approval.
The Constitutional Guardrail
The core of the dispute rested on a singular, aggressive interpretation of the IEEPA. The administration argued that the power to "regulate importation" during a national emergency granted the executive branch a blank check to levy duties. Katyal’s counter-argument was surgically precise. He argued that for 238 years, whenever Congress intended to delegate its power to tax, it did so with explicit language, clear floors, and defined ceilings.
The Supreme Court agreed. Chief Justice John Roberts, writing for the majority, noted that the IEEPA contains no mention of "tariffs," "duties," or "taxation." The ruling affirmed that while a president can respond to emergencies, they cannot unilaterally rewrite the nation’s tax code under the guise of national security. This decision immediately invalidated the 10% baseline tariff on all global imports and the escalating reciprocal tariffs that had reached as high as 41% for certain trading partners.
The $200 Billion Refund War
Winning the case was the beginning. The aftermath has triggered a logistical and legal nightmare for the Treasury. Estimates suggest that between $175 billion and $200 billion in unlawfully collected tariffs are currently sitting in government coffers. Katyal has already launched a dedicated legal task force to claw this money back for the thousands of small businesses and manufacturers he represented.
The administration’s defense has been one of tactical retreat. During oral arguments, government lawyers assured the court that if the tariffs were struck down, refunds would be "automatic." Now that the verdict is in, the White House has pivoted, suggesting that the "refund process" must be litigated individually in the Court of International Trade.
Katyal is calling the bluff. On February 24, he filed coordinated motions to force immediate issuance of the mandate. The goal is to bypass the typical 25-day waiting period and trigger the checks. For many mid-sized American manufacturers who have been operating on razor-thin margins since the 2025 trade wars began, these refunds are not a bonus; they are a solvency requirement.
The Section 122 Pivot
The administration did not take the defeat quietly. Less than 24 hours after the ruling, the White House invoked Section 122 of the Trade Act of 1974. This "arcane" provision allows for a temporary 150-day import surcharge of up to 15% to address "large and serious" balance-of-payments deficits.
This is where the next legal battle is already being mapped out. Katyal has pointed out a glaring contradiction in the government’s own record. During the IEEPA litigation, the Department of Justice explicitly told the Court that Section 122 did not apply to the current economic situation because "trade deficits" are conceptually distinct from "balance-of-payments deficits."
By pivoting to Section 122, the administration is now making the exact argument its own lawyers previously dismissed as legally unfounded. This inconsistency is more than a rhetorical slip. It provides Katyal and his team with a ready-made "estoppel" argument for the next round of injunctions. If the government argued in 2025 that Section 122 wasn't the right tool, they face an uphill battle explaining why it suddenly became the only tool in 2026.
A Career of Testing Limits
To understand why Katyal was the one to pull this off, you have to look at the trajectory of a career spent obsessed with the boundaries of executive power. This is the same lawyer who, as a young professor, took on the Bush administration in Hamdan v. Rumsfeld, successfully arguing that the Guantanamo military commissions were illegal.
He has now argued over 50 cases before the Supreme Court, surpassing the record for any minority attorney in U.S. history. His approach is rarely about the "vibe" of the law or the political popularity of a policy. It is about the plumbing of the Constitution. Whether defending the Voting Rights Act or challenging the 2017 travel ban, Katyal’s strategy remains consistent: force the court to look at the text and the history of delegated power.
During the tariff litigation, Katyal posted a photo on social media of his kada—a Sikh steel bracelet symbolizing moral accountability—resting on his legal briefs. It was a subtle nod to his background as the son of Indian immigrants, but also a signal of the "Punjabi spirit" he often cites: a refusal to be intimidated by the scale of the opponent.
The End of the Blank Check
The implications of this ruling extend far beyond the current trade war. It sets a precedent that will haunt future administrations of any party. If a president wants to enact a "Green New Deal" or a "National Security Border Tax" by declaring an emergency, they now face a Supreme Court that has clearly stated: go through Congress.
The era of "government by executive order" in the economic sphere has hit a constitutional wall. The 6-3 split, which saw conservative justices like Amy Coney Barrett and Brett Kavanaugh siding with the liberal wing on the core structural question, suggests that the "Major Questions Doctrine" is now the primary tool for checking executive overreach.
The White House may have 150 days of breathing room under Section 122, but the clock is ticking. When those five months expire, the administration will either have to persuade a fractured Congress to pass a new tariff law or face another humiliating day in court against a legal team that has already proven it knows exactly where the President’s power ends.
The next step is for businesses to audit their 2025 customs entries to prepare for the looming refund litigation. Would you like me to draft a breakdown of the specific harmonized tariff codes most likely to be eligible for immediate reimbursement under the Katyal task force’s framework?
