Madison Called It the Very Definition of Tyranny, and Agencies Hold All Three

Suppose a stranger handed you a short description of a government. It writes the rules. It investigates whether you broke them. It prosecutes you before a judge it employs. And it decides whether you lost. You would not call that a republic. You might not call it a government at all. James Madison had a word for it, and he put the word in a sentence that every American student should be able to recite.

That sentence is in Federalist 47, published in early 1788 to answer a charge against the proposed Constitution. Let us read the essay the way it deserves to be read: slowly, passage by passage, and then hold it up to the machinery of the modern agency.

The charge Madison was answering

The Constitution had opponents, and some of their best arguments were sharp. One of them went like this: the great political authority Montesquieu taught that liberty requires the separation of the legislative, executive and judicial powers. The proposed Constitution, the critics said, does not separate them. The President takes part in lawmaking through the veto. The Senate takes part in appointments and treaties and sits as the court of impeachment. The Chief Justice presides over that trial. Therefore, they said, the new government violated the very maxim it claimed to honor.

Madison's answer is the substance of Federalist 47, and it has two halves. The first is a statement of principle, the one we remember. The second is a defense of the Constitution's design: that "separation" never meant what the critics said it meant.

Passage one: the definition

Here is the sentence:

The accumulation of all powers, legislative, executive, and judiciary, in the same hands, whether of one, a few, or many, and whether hereditary, self-appointed, or elective, may justly be pronounced the very definition of tyranny.

Take it in pieces, because Madison chose each phrase. "The accumulation of all powers": not the mere existence of any combined authority, but the gathering of all three. "In the same hands": the test is about who holds the power, not about what label is on the door. "Whether of one, a few, or many": the danger does not depend on the number. A committee tyrannizes as well as a king. "And whether hereditary, self-appointed, or elective": the danger does not depend on how the holders got there. An elected body that holds all three powers is still tyrannical.

That last phrase is the one for our age. Many people think that if officials are chosen by the voters, or answer ultimately to officials the voters chose, the problem is solved. Madison says no. Election of the holders does not cure the accumulation of the powers. The structure itself is the problem.

Passage two: Montesquieu, the oracle

Madison next turns to the source. He writes that "the oracle who is always consulted and cited on this subject is the celebrated Montesquieu." Montesquieu was the French political philosopher whose Spirit of the Laws (1748) had described the British constitution as a model of liberty, thanks to its division of authority.

Madison reports Montesquieu's key maxims. When the legislative and executive powers are united in the same person or body, there can be no liberty, because the same monarch or senate may enact tyrannical laws and then execute them tyrannically. And there is no liberty if the judicial power is not separated from the legislative and executive. If the judicial power were joined to the legislative, the life and liberty of the subject would be exposed to arbitrary control, because the judge would then be the legislator. If it were joined to the executive, Madison writes, "the judge might behave with all the violence of an oppressor."

Notice the three pairings. Legislative with executive: the lawmaker also enforces. Judicial with legislative: the judge also makes the law. Judicial with executive: the judge is also the prosecutor. Each pairing is a failure by itself. All three together are what Madison calls tyranny.

Passage three: what Montesquieu did not mean

This is the part critics skip, and it is where Madison is most useful. He observes that Montesquieu was describing the British Constitution, in which the King, the executive magistrate, took a part in lawmaking and in appointing judges. If Montesquieu thought the British system preserved liberty, he could not have meant that the three departments must have no connection or control over each other.

Madison's conclusion: Montesquieu's maxim means only that where the whole power of one department is exercised by the same hands that hold the whole power of another, the fundamental principles of a free constitution are subverted. A partial agency of one department in the acts of another is a different matter. The President's veto, the Senate's role in appointments, the House's power to impeach: each is a limited overlap that works as a check. None is a transfer of the whole function.

That distinction, whole power versus partial agency, is the key to everything that follows. The Constitution is full of intentional overlap, which is precisely how the departments restrain each other. What it forbids is consolidation.

Passage four: the state constitutions

Madison then does something characteristic. He goes to the evidence. He surveys the constitutions of the states, the ones the critics admired, and shows that none of them maintained a complete separation. In state after state, he notes, the legislature appointed the governor or the judges and other officers, and some states gave their senates a role in impeachment trials. Several of them declared the departments "separate and distinct" and then mixed them anyway, in ways the proposed federal Constitution did not. If the critics wanted a pure separation, they would have to condemn the very state governments they cited as examples of liberty.

So Madison's argument has an empirical backbone: the separation of powers as the American tradition practiced it was never a wall but a balance. The sentence in Federalist 51 follows from it: "Ambition must be made to counteract ambition." The overlap is the machinery by which each branch resists the others. The thing that must not happen is the accumulation of all three in one place.

Now map the three powers onto an agency

Madison wrote in 1788 about a legislature, an executive and a court. He had not seen a modern federal agency. But a modern agency is the most efficient illustration of his warning, and the mapping is worth doing carefully, because it is not a rhetorical trick. It follows the statutes.

Legislative power: the rule. A statute gives an agency authority to issue regulations. Under the Administrative Procedure Act, section 553, the agency publishes a proposed rule, collects public comments, and issues a final rule. A final rule has the force of law. A person who violates it can face fines, penalties, even criminal charges when the statute so provides. The agency has not "interpreted" a law. It has made a binding general rule of conduct, which is what a legislature does. The Federal Register carried 3,248 final rules in 2024 and, by the count of the Competitive Enterprise Institute, 2,441 in 2025. Compare that with the number of laws Congress passes in a year, a few hundred at most, and the scale of the delegation is evident. See Agencies Write Thousands of Rules a Year While Congress Passes Hundreds of Laws.

Executive power: the investigation and enforcement. The same agency has inspectors, auditors and enforcement attorneys. It issues subpoenas and demands for documents. It decides which regulated parties to investigate, which violations to pursue and which to ignore. It chooses to settle or to charge. That is executive power in its classic form: deciding whom the law will be enforced against.

Judicial power: the hearing. Many agencies also decide the cases they bring. In a formal agency adjudication, an administrative law judge conducts a hearing, takes evidence, and issues an initial decision, which the agency's head or commission may review. The judge is employed by the agency. The agency is the prosecutor. The agency's commissioners are the court of last resort inside the building. If the respondent loses, the first appeal goes to a federal court, but only after the agency has finished with the case, and, under the deference the courts have long given, on a record the agency built.

Now do the arithmetic Madison would do. One entity writes the rule, decides who has broken it, runs the proceeding to find the facts, and rules on the penalty. It is not exactly the "same hands" of a single person, but it is the same institution, answerable in the first instance to the same head. Madison's test was about the accumulation of the powers "in the same hands." The agency is the paradigm.

The defense, stated at its strongest

A fair reader should hear the best answer, and there is a serious one.

The defense says: the separation is internal, and it is enough. Inside a well-run agency, the people who write the rules are not the ones who investigate, and neither group is the group that adjudicates. The APA itself provides that in a formal adjudication the investigator or prosecutor may not participate in the decision or advise the decision-maker (5 U.S.C. section 554(d)). Administrative law judges have protections from improper pressure. Agency decisions are subject to judicial review. Congress oversees the agencies through its appropriations and its hearings. The President directs the executive agencies. And the real alternative, handing every dispute to a federal court and every detail to a statute, would be unworkable in a modern economy. The three powers, in short, are mixed in the agency but divided among its offices, with courts and Congress watching.

I would grant the premise that an agency is not a single person and that its offices have internal walls. Those walls are better than none. But the defense fails for five reasons.

1. Internal walls are made by the people they restrain. Madison's remedy for the accumulation of power was never to trust the holder of power to limit himself. It was to set a different institution against him, one with its own ambition and its own interest. An internal separation is a policy; the Constitution's separation is a structure. A policy can be rewritten by the head of the agency. The Constitution cannot.
2. The separation Madison cared about runs through independent institutions, not offices. Congress, the President and the courts are distinct because they are chosen differently, serve different terms, and answer to different constituencies. A division of labor within a single agency is a management chart, not a check.
3. Deference tilts the last stage. For decades the courts deferred to agencies' readings of their own statutes, and agencies came to treat the judiciary as a reviewer of last resort rather than an independent power. The Supreme Court's decision in Loper Bright Enterprises v. Raimondo (2024) overruled the old Chevron doctrine and told courts to exercise independent judgment. That decision is a step toward restoring the check, and it was needed precisely because the check had weakened.
4. The jury is part of the structure. In SEC v. Jarkesy (2024) the Court held that when the SEC seeks civil penalties for securities fraud, the Seventh Amendment entitles the defendant to a jury in a court. The case is a reminder that where the agency tries to take over the job of the courts, the Constitution has an answer. See SEC v. Jarkesy Put the Jury Back Between Citizens and Agency Courts.
5. Oversight is thin. Congress can hold a hearing. It cannot read every rule. A President directs the executive branch, but the permanent staff outlasts him. The practical reality is that a large share of the day-to-day power rests with officials the voters never see.

Where the fix begins

Madison's remedy is not to abolish agencies. The Constitution contemplates executive departments, and Congress has the power to create them. The remedy is to restore the departments to their own functions: legislative decisions are made by Congress, executive actions are checked by executive officers answerable to the President, and judicial decisions are made by judges.

Here are practical steps that follow from his text, each one consistent with the Constitution.

• Congress writes the major rules. If a regulation will impose billions in costs or alter the structure of an industry, a vote of both houses and the President's signature should be required. The REINS Act proposal does this, and Make Congress Vote on Every Major Rule, and Watch Accountability Return explains why. The principle behind it is stated in The Nondelegation Doctrine Says Congress Cannot Hand Its Job to Someone Else.
• Courts decide questions of law. After Loper Bright, a court reads the statute for itself. The agency's view gets respect for its persuasiveness, not deference to its authority.
• Penalties go to a judge and jury. Where the government wants to take property, impose heavy fines or label someone a fraudster, the forum should be an ordinary court.
• The President answers for the agencies. A chain of command that ends at the President is a feature, because he is elected. The unelected "independent" commission that no President can direct is the structure Madison would have asked hardest questions about; see Humphrey's Executor Created a Fourth Branch the Constitution Never Mentions.

The measure for a republic

Federalist 47 has lasted because it gives us a simple test that does not depend on partisanship. Ask: who writes the rule, who enforces it, and who judges the dispute? Are they the same hands? If the answer is yes, the structure invites the tyranny Madison defined, whatever the intentions of the people in it. Good people can run a bad structure for a time. The point of a constitution is that you do not have to hope for them.

And notice that the argument cuts both ways. A conservative administration that rules through agency guidance has the same problem as a progressive one. The principle that protects a family from an agency it dislikes also protects it from an agency it likes. That is what it means to have a Constitution rather than a mood.

The case in brief

1. Federalist 47 defines tyranny as the accumulation of legislative, executive and judicial power in the same hands, "whether hereditary, self-appointed, or elective."
2. Madison, relying on Montesquieu and the state constitutions, distinguishes a partial overlap that works as a check from the consolidation of a whole power, which destroys liberty.
3. A modern agency writes binding rules, investigates and prosecutes violations, and often hears the case through its own judges, which brings all three functions under one roof.
4. The defense that internal separation is enough fails because internal walls are written and rewritten by the very officials they restrain, while the Constitution's separation runs between independent institutions.
5. The cure is to return each power to its department: Congress writes major rules, courts read the law for themselves, juries decide when the government seeks heavy penalties, and the President answers for the executive branch.
