Most people who argue about constitutional rights have never read Article VI carefully. They talk about the First Amendment, the Second Amendment, the Bill of Rights. They quote Marbury v. Madison. But the provision that actually controls all of it sits in Article VI, and most of the time it gets treated like fine print nobody is supposed to notice. That is not an accident.
What Article VI Actually Says
The text is short. “This Constitution, and the Laws of the United States which shall be made in Pursuance thereof, and all Treaties made, or which shall be made, under the Authority of the United States, shall be the supreme Law of the Land; and the Judges in every State shall be bound thereby.”
Read it again slowly. It does not say every federal statute is supreme law. It does not say whatever Congress passes gets wrapped in constitutional dignity simply because Congress passed it. It says the Constitution is supreme, and only laws made “in Pursuance” of it share that supremacy. That phrase is doing all the work. It is a gate. Before a federal statute gets to call itself supreme law, it has to pass through the constitutional text first. If it does not, Article VI does not lift it up. It leaves it on the floor.
The Kill Switch
Hamilton explained the logic in Federalist No. 78. “No legislative act, therefore, contrary to the Constitution, can be valid.” He called the alternative absurd: to say otherwise would be to say “the deputy is greater than his principal,” that the representatives are above the people themselves.
That is the whole structure in two sentences. The Constitution is higher law because it comes from the people in their sovereign capacity. Statutes are lower law because they come from agents with limited, delegated power. When those two things collide, the lower gives way to the higher. That is not judicial supremacy. That is constitutional supremacy. Courts are not above the legislature. The Constitution is above both.
Marbury v. Madison gave this principle its famous formulation: “a law repugnant to the Constitution is void.” People quote that line as if Marshall invented the idea. He did not. He applied a rule that was already built into Article VI, already explained in the Federalist Papers, and already put into practice by courts before Marbury ever reached the Supreme Court.
How Courts Keep the Words and Kill the Meaning
The problem is that pulling the switch has consequences. Courts that actually enforce Article VI have to strike down laws that powerful people want kept. So modern constitutional law has developed a set of techniques for making sure the switch almost never gets pulled, while still quoting Article VI in the opening paragraphs of every opinion.
The first technique is the category trick. Instead of admitting a conflict between a statute and the Constitution, courts say there is no conflict because the right never applied to this person in the first place. Once that move is accepted, Article VI never gets triggered.
The second technique is redefining the right. When courts cannot easily deny that a right covers someone, they shrink what the right means. After Heller and Bruen, some courts rebranded the Second Amendment from “the right of the people to keep and bear arms” into something narrower. Once the right is that small, broad disarmament of disfavored groups stops looking like a direct collision with the text.
The Practical Consequence
Article VI is not background music. It is the enforcement mechanism of the entire constitutional order. When a statute collides with the Constitution, the Supremacy Clause asks one question: was this law made in pursuance of the Constitution? If the answer is no, the law is void. Not voidable. Not presumptively valid. Not subject to being saved by a sufficiently compelling government interest. Void. As in, it never had the right to rule in the first place.
The words have not changed. “In Pursuance thereof” still means what it said in 1787. Laws that do not pass through that gate are not supreme. They are nullities. And a government that enforces nullities while quoting the Constitution in the same breath is not living under the rule of law. It is performing it.
