What Makes Something Law? John Austin's Surprising Answer

Imagine you’re playing a board game with friends. Someone accuses you of breaking a rule. You check the rulebook. The rule is there, clear as day. But then someone says: “That rule is stupid and unfair. It shouldn’t count.”

Now here’s a strange question: Is it still a rule?

Most of us would say yes. A rule is a rule, even if it’s a bad one. But what about laws? If a law is cruel or unjust—like a law that says one group of people can own another—is it still actually law? Or does something stop being a real law if it’s too evil?

This is the question that obsessed a frustrated English lawyer named John Austin in the 1800s. And his answer was so simple and sharp that people are still arguing about it today.


A Man Who Failed at Almost Everything (But Changed How We Think About Law)

John Austin had a tough life. He was born in 1790, trained as a lawyer, but barely practiced—he was too nervous, too sickly, too perfectionistic. He got a job teaching law at a new university in London, prepared for years, and then almost nobody came to his classes. He quit. He tried government work. That didn’t work out either. He spent his later years depressed, unable to finish the books he wanted to write.

But here’s the thing: the one book he did publish—a short, dry, difficult work called The Province of Jurisprudence Determined (1832)—ended up being one of the most important books ever written about law. After Austin died, his wife Sarah worked tirelessly to spread his ideas. And within a few decades, Austin’s way of thinking had become the standard way law was taught in England.

What made his ideas so powerful? And why do so many people today think he was wrong?


The Separation of Law and Morality

Before Austin, most thinkers about law treated it as a branch of morality. They asked: What makes a good law? When is it okay to disobey? The assumption was that law and justice were deeply connected—maybe even that an unjust law wasn’t really a law at all.

Austin thought this was a mistake. He wanted to study law scientifically, the way you might study rocks or planets. Not “What should the law be?” but “What is law?” Not “Is this law good?” but “Is this law actually law?”

Here’s his most famous statement, which became the slogan of an entire movement called legal positivism:

“The existence of law is one thing; its merit or demerit is another. Whether it be or be not is one enquiry; whether it be or be not conformable to an assumed standard, is a different enquiry. A law, which actually exists, is a law, though we happen to dislike it.”

Translation: You can’t decide whether something is a law by asking whether it’s fair. A horrible law is still a law. A beautiful, perfectly just suggestion is not a law unless someone with authority made it one.

This is the core idea of legal positivism: we can describe what law is without saying anything about whether it’s good or bad.


The Command Theory of Law

So if law isn’t about morality, what is it? Austin’s answer was simple and brutal. Law, he said, is just a command from a sovereign backed by a threat.

Let’s break that down.

Command. Someone with authority tells you to do something (or not do something). That’s a command, not just a suggestion.

Sovereign. This is a person or group that most people habitually obey, but that doesn’t habitually obey anyone else. In Austin’s day, he awkwardly described the British sovereign as “the King, the House of Lords, and all the electors of the House of Commons”—a messy combination because he couldn’t find one clear ruler.

Backed by a threat (a “sanction”). If you don’t obey, something bad will happen to you. That “evil,” as Austin called it, is what makes the command a law rather than just friendly advice.

So for Austin, law = “Do this or else.” The “or else” is what makes it law. No threat, no law.

This fits some laws perfectly. “Don’t steal, or you’ll go to jail.” Yes, that’s clearly a command from a sovereign with a sanction. But does it fit all laws?


The Problems With Austin’s Theory

Almost as soon as Austin’s theory became famous, people started poking holes in it. Here are the biggest ones.

Problem 1: Where’s the sovereign?

In many countries, it’s hard to point to one person or group that “habitually obeys nobody.” In the United States, for example, the Constitution limits everyone—including Congress and the President. There’s no single sovereign. Austin himself struggled with this. For Britain, he ended up saying the sovereign was a weird mix of King, Lords, AND voters. That doesn’t feel like one clear ruler.

And what happens when a new leader takes over? A new president doesn’t have a “habit of obedience” from anyone yet. No habit, no sovereign, no law. That can’t be right—we know laws exist even during transitions.

Problem 2: Not all laws are commands

Think about laws that let you do things, not forbid you. The law that lets you make a will. The law that lets you sign a contract. The law that lets you start a corporation. These aren’t “do this or else” commands. They’re more like: “If you want to do X, here’s how to do it properly.”

Austin tried to handle this by saying the “sanction” for messing up is nullity—your will or contract just doesn’t count. But this seems to miss the point. These laws aren’t about punishing bad behavior; they’re about giving people power to arrange their own affairs.

Problem 3: International law

Countries make treaties. There are rules about how nations should treat each other. Almost everyone calls this “international law.” But there’s no world sovereign with a police force to enforce it. According to Austin’s definition, international law isn’t really law at all. He said it was just “positive morality”—customs that countries follow, but not actual laws.

This bothers a lot of people. It seems like international law matters, even if enforcement is messy.

Problem 4: The gunman analogy

If law is just a command from someone powerful enough to hurt you, how is a legal system different from a gangster pointing a gun at you and saying “your money or your life”? Both are commands backed by threats. Both come from someone with power. But we feel they’re different. Most people think a real legal system has some legitimacy—citizens accept the law as something they ought to follow, not just something they’re forced to follow.

Austin’s theory has trouble explaining this difference.

Problem 5: The rules about making rules

Here’s a tricky one. In every legal system, there are rules about who can make laws and how. For example: “A bill becomes law when the President signs it.” This rule isn’t a command. It’s not telling anyone “do this or else.” It’s more like a recipe. But without these rules, you couldn’t identify any laws at all. Austin’s theory seems to leave no room for them.


Why Bother With a Flawed Theory?

You might wonder: why are we talking about a theory that has so many problems? Two reasons.

First, Austin was the first person to ask the question that way. Before him, people mostly studied law by studying history, or customs, or morality. Austin said: let’s just look at what law is, as a thing in the world, the way a biologist looks at a cell. This might seem obvious now, but it was radical then. It created a whole new way of thinking about law.

Second, even though his specific answers were flawed, his basic insight—that we need to separate the question “Is this law?” from “Is this good law?”—is still central to how philosophers think about law today. The most famous legal philosopher of the 1900s, H.L.A. Hart, built his entire theory by criticizing Austin and then fixing the problems. Hart’s theory is much more complicated. But he started from Austin.

Some modern thinkers even appreciate Austin’s theory because of its flaws. They argue that Austin was more honest than later theorists about the connection between law and power. His theory doesn’t pretend that law is always noble or just. It says: law is what people with power say it is. That’s uncomfortably realistic. When governments do terrible things using law (like Nazi Germany’s laws against Jews), Austin’s theory says: yes, those were laws. They were horrible. But they were still laws.

This doesn’t mean we have to obey bad laws. But Austin thought we should be clear about what we’re saying. If you disobey a law because it’s unjust, you should say “I’m breaking a real law because it’s wrong,” not “this isn’t a real law because it’s wrong.” The difference matters.


The Debate That Won’t Die

Philosophers still argue about all of this. People who believe in “natural law theory” think Austin had it backwards—they argue that there is a connection between law and morality, and that a truly unjust law isn’t really a law at all. Legal positivists think Austin was basically right about separating law from morality, even if his particular theory needs fixing.

John Austin died in 1859, convinced he had failed at everything. He would probably be amazed to learn that 150 years later, students are still reading his work, and philosophers are still arguing about his simple, brutal idea: that law is just a command, backed by a threat, from whoever holds the power.

Maybe he wouldn’t be surprised at all. Maybe he’d just say: “That’s how it is. I told you so.”

Key People

  • John Austin (1790–1859) — An English lawyer and philosopher who failed at most things in life but wrote a book that changed how people think about law. He argued that law is just a command from a sovereign backed by a threat.
  • H.L.A. Hart (1907–1992) — A later legal philosopher who revived legal positivism by criticizing Austin’s theory and building a more sophisticated version. He argued that Austin missed the way people accept laws as reasons for action, not just things they fear.
  • Jeremy Bentham (1748–1832) — Austin’s mentor, a radical philosopher who had similar ideas about law but whose work wasn’t published until much later. Austin gets the credit because Bentham’s thoughts weren’t widely available.

Things to Think About

  1. If Austin is right that a terrible law is still a law, what does that mean for people who disobey unjust laws? Should a judge enforce a law they think is evil? If they refuse, are they breaking the law?

  2. Austin’s theory says law depends on who has the power. Does that mean a rebel group that controls part of a country is making “real law” for the people in that area? Where do you draw the line between a government and a gang?

  3. If you could pass one law right now, what would it be? According to Austin, what would need to be true for it to count as a real law—just that it’s a good idea, or something else?

  4. Hart criticized Austin for ignoring how people accept laws internally, not just obey from fear. Think of a rule you follow even when no one is watching. Why do you follow it? Would that count as a “law” under Austin’s theory?

Where This Shows Up

  • In school: When a teacher says “that’s the rule” and you argue “but that’s not fair,” you’re having the Austin debate. Is it still a rule even if it’s unfair?
  • In history class: When you study Nazi Germany, apartheid South Africa, or slavery in the United States, you’re looking at legal systems that made horrible things legal. Austin’s theory says: yes, those were laws. Do you agree?
  • In the news: When people argue about whether something a government does is “legal but wrong” or “not really law because it violates human rights,” they’re replaying the fight between legal positivism and natural law theory.
  • In video games: When a game has rules that let you do things (craft items, build structures) rather than just forbid you (don’t go out of bounds), that’s like the “power-conferring” rules that Austin’s theory struggles to explain.
