There is a legal principle that modern courts work very hard to avoid. It is not obscure. It is not controversial in the abstract. Every judge in America will tell you they believe it. The moment it gets applied to a law they want to preserve, it disappears from their opinions as if it never existed. The principle is void ab initio. It means void from the beginning. And the Supreme Court stated it plainly in 1886 in Norton v. Shelby County: an unconstitutional act “is not a law; it confers no rights; it imposes no duties; it affords no protection; it creates no office; it is, in legal contemplation, as inoperative as though it had never been passed.”
The Difference Between Void and Voidable
Modern constitutional law operates almost entirely on a voidable model. Under that model, a law remains valid and enforceable until a court decides to strike it down. Norton says that is wrong. The void ab initio doctrine rests on a simple logical premise: if the Constitution is genuinely higher law, and if a statute contradicts it, then the statute never had valid legal existence. A court that later declares the statute unconstitutional is not destroying something that previously had legal force. It is recognizing a fact that was true from the beginning.
The Relationship to Article VI
The void ab initio doctrine is not a separate theory. It is the operational consequence of Article VI’s Supremacy Clause. Article VI says only laws made “in Pursuance” of the Constitution are supreme law. That clause is a gate. A statute that contradicts the Constitution never passes through the gate. It never achieved the status of supreme law. Marbury v. Madison stated the principle in 1803: “a law repugnant to the Constitution is void.” Norton sharpened it in 1886 by making explicit what void actually means. Together, they establish a complete framework. Everything built on a void law, including prosecutions, disabilities, and administrative denials, is built on nothing.
What the Doctrine Requires
Void ab initio is not a gentle doctrine. It asks a single question: does this law pass through the Article VI gate? If the Second Amendment is a negative command and the law contradicts that command, the answer is no. The law is void. It was void the day Congress passed it. It remains void today. Every prosecution under it has rested on a legal nullity. Courts can continue to avoid saying this. But the doctrine has not changed. An unconstitutional act is not a law. It confers no rights, imposes no duties, and affords no protection. It is as inoperative as though it had never been passed. That is Norton v. Shelby County. It is binding precedent. It is still on the books.
