In a landmark decision in Learning Resources v. Trump / V.O.S. v. Trump, No. 24-1287, the United States Supreme Court reaffirmed one of the most fundamental principles of American constitutional law:
The power to tax belongs to Congress—not the President.
The ruling is a powerful victory for the U.S. Constitution’s Separation of Powers and for the rule of law.
It is also deeply aligned with the constitutional arguments presented in the Biazzo Law Amicus Curiae Brief filed in the case on October 8, 2025.
The Constitutional Question Before the Court
At issue was whether the President could rely on the International Emergency Economic Powers Act (IEEPA) to impose sweeping tariffs—without express congressional authorization.
As one amicus briefer aptly summarized:
“The President claimed the power to impose, reduce, hike, suspend, double, treble, or eliminate tariffs all on his own. No law allows that—least of all the Constitution.”
The Supreme Court agreed.
The Supreme Court’s Core Holding: Article I Means What It Says
The Constitution provides in Article I, Section 8:
Congress shall have Power to lay and collect Taxes, Duties, Imposts and Excises.
Tariffs are duties. Duties are taxes.
The Court rejected the argument that IEEPA’s authorization to “regulate importation” silently included the power to impose revenue-raising tariffs.
This holding directly reflects the central thesis of the Biazzo Law amicus brief:
The President has no inherent constitutional authority to impose tariffs.
IEEPA is a sanctions statute—not a revenue statute.
Congress must speak clearly when delegating power of vast economic and political significance.
The majority opinion confirmed each of those structural principles.
Strong Alignment Between the Biazzo Law Brief and the Majority Opinion
The alignment between our brief and the Court’s ruling is substantial and doctrinally significant.
1️ Article I Taxing Power Is Exclusive to Congress
Our brief argued:
Tariffs are taxes.
The power to impose taxes is exclusively legislative.
Executive orders cannot manufacture taxing authority.
The Supreme Court reinforced that the Constitution does not permit the Executive Branch to assume Congress’s taxing power absent clear statutory authorization.
This is textbook Separation of Powers doctrine.
2️ IEEPA Is Not a Tariff Statute
The Biazzo Law brief emphasized that:
IEEPA authorizes blocking and regulating transactions.
Its verbs are sanctions-oriented—not taxation-oriented.
It does not mention tariffs.
The Court agreed, holding that IEEPA does not grant the “distinct and extraordinary” authority to raise revenue.
Congress knows how to delegate tariff authority—and has done so in other statutes with guardrails and limits. It did not do so here.
3️ The Major Questions Doctrine Applies
Our amicus brief expressly argued that a nationwide tariff regime is a paradigmatic “major question.”
The Supreme Court applied that doctrine, requiring clear congressional authorization before allowing such sweeping economic power to shift to the Executive Branch.
This aligns with recent landmark decisions involving:
Student loan cancellation
EPA regulatory overreach
Administrative agency power limits
The Court once again made clear:
Major economic policy decisions must come from Congress.
Why This Ruling Is a Victory for Separation of Powers
The Separation of Powers is not a technicality. It is the structural foundation of liberty.
As explained in the Biazzo Law brief:
Each branch of government has defined constitutional lanes.
The Executive enforces the law.
Congress makes the law.
The Judiciary interprets the law.
Allowing the President to unilaterally impose nationwide tariffs would collapse that structure—concentrating legislative and executive authority in a single branch.
The Supreme Court refused to permit that shift.
The decision preserves:
Bicameralism
Presentment
Democratic accountability
Constitutional guardrails on taxation
In short, it protects the Constitution’s structural integrity.
Why This Matters for Businesses and the Rule of Law
For businesses, regulatory certainty matters.
For citizens, constitutional certainty matters even more.
If IEEPA could be read to authorize unilateral tariff regimes:
Any President could impose or eliminate tariffs at will.
Economic policy could change overnight by executive decree.
The power to tax could shift away from elected legislators.
The Court rejected that instability.
The Constitution requires Congress to speak clearly before transferring such enormous power.
Supreme Court Litigation Requires Structural Constitutional Advocacy
Cases like this demonstrate why sophisticated constitutional briefing at the U.S. Supreme Court level matters.
As a U.S. Supreme Court Appeals Lawyer, Corey J. Biazzo focuses on:
Constitutional law
Separation of powers
Federal appellate litigation
Supreme Court advocacy
The Biazzo Law amicus brief emphasized foundational principles that were ultimately reflected in the Court’s majority reasoning.
When cases implicate:
Article I powers
Executive authority
Major questions doctrine
Structural constitutional limits
Strategic, historically grounded advocacy is critical.
The Broader Constitutional Impact
This ruling reinforces several enduring principles:
The President is not above the Constitution.
Congress cannot silently transfer core legislative powers.
Major economic decisions require clear legislative authorization.
The Separation of Powers remains enforceable—not symbolic.
In reaffirming those principles, the Supreme Court protected not only statutory interpretation norms—but the architecture of the Constitution itself.

Final Thought
The Supreme Court’s decision in Learning Resources v. Trump is more than a tariff case.
It is a reaffirmation that:
The United States is a government of laws—not of men.
And the Constitution’s Separation of Powers still means what it says.
