Inherent Contempt: Congress Already Has the Power to Enforce Its Own Subpoenas

Here is a fact that should unsettle anyone who cares about the separation of powers: Congress already possesses the constitutional authority to arrest and detain a witness who defies a lawful subpoena. That power, called inherent contempt, was used by the founding-era Congress, confirmed by the Supreme Court from Anderson v. Dunn in 1821 to Jurney v. MacCracken in 1935, and then abandoned. Not repealed. Not declared unconstitutional. Abandoned.

I am not suggesting Congress should start throwing people into a Capitol basement on a whim. I am saying that the loss of this power, and its replacement by a process that requires the executive branch to prosecute its own misconduct, is one of the quietest and most consequential constitutional developments of the past century. We have made Congress a paper tiger, and then we wonder why oversight has become theater.

Investigation is not a courtesy; it is a legislative function

The Constitution vests all legislative powers in Congress. The Supreme Court has long recognized that the power to legislate necessarily includes the power to investigate, and that the power to investigate is useless without the power to compel testimony and evidence. In McGrain v. Daugherty, the Court said exactly that: the power of inquiry, with process to enforce it, is an essential and appropriate auxiliary to the legislative function.

Early Congresses understood this. Before the modern bureaucracy existed, the House and Senate did not ask a United States attorney to help them enforce subpoenas. They directed their Sergeant-at-Arms to arrest contumacious witnesses and bring them before the chamber. The detained witness was held not as a criminal punishment but as a coercive remedy: comply with the subpoena, and you go free; refuse, and you remain detained until the end of the session. The process was limited by its purpose and by its duration.

The originalist case for inherent contempt is strong. Founding-era legislatures possessed contempt power as part of what it meant to be a legislative body, and the Constitution must be read as those who ratified it understood it. The Supreme Court repeatedly upheld the power, with an important qualification: it is not an arbitrary power to punish enemies, but a power confined to removing the obstruction of the legislative function. A detained witness could still seek habeas corpus review in federal court. That is a real check, not a blank check.

The last actual use of inherent contempt came in 1935, when the Senate arrested William MacCracken for destroying documents after a subpoena. Since then, Congress has almost entirely stopped using its own power.

How the power actually worked

It helps to picture the mechanism, because modern Americans have never seen it operate. In an early Congress, if a witness refused to answer a proper legislative question, the full House or Senate would vote on a resolution finding the witness in contempt. The Sergeant-at-Arms would then be authorized to take the person into custody and bring him before the bar of the chamber. The witness was not sentenced to a fixed prison term. He was detained until he complied with the subpoena or until the legislative session came to an end, whichever happened first.

That distinction matters enormously. Inherent contempt is not criminal punishment. It is a civil, coercive measure designed to make the legislature's investigation possible. The witness always held the key to his own release: answer the question, produce the documents, and walk out. Refuse, and the detention continued, but it could not outlast the session that needed the testimony.

The courts kept guard over the process. A person held for inherent contempt could go to federal court and challenge the detention through habeas corpus. If the detention stopped being coercive and became punitive, or if it strayed beyond the legislative purpose, the courts could order release. That is not the stuff of tyranny. It is a carefully bounded constitutional power.

The modern substitute is a constitutional absurdity

Today, when a witness defies a congressional subpoena, Congress almost never uses inherent contempt. Instead, it relies on a criminal contempt statute, first passed in 1857, under which the House or Senate certifies the refusal to a United States attorney. The prosecutor is supposed to bring the matter before a grand jury. But here is the problem: when the witness is an executive branch official, or when the material sought involves executive privilege, the referral goes to the very executive branch that is often the target of the investigation. The president's own appointees decide whether the legislature gets the information it is constitutionally entitled to.

That is not separation of powers. That is a permission slip.

The 2012 confrontation over Operation Fast and Furious is the clearest modern example. The House held Attorney General Eric Holder in contempt for refusing to turn over documents. The criminal referral went to the Department of Justice, the department he led. Unsurprisingly, the department declined to prosecute. Whether you believe the documents should have been produced or not, the structure of enforcement was absurd. The executive branch was given a veto over the legislative branch's investigation into the executive branch.

The same flaw appeared in 2008, when the House held White House Counsel Harriet Miers and Chief of Staff Joshua Bolten in contempt for refusing to cooperate with an investigation into the firing of United States attorneys. The Department of Justice declined to present the contempt citation to a grand jury. The House then had to file a civil lawsuit in federal court, which dragged on for months and was ultimately settled after the administration changed. The information sought was eventually produced, but the delay made a mockery of the oversight function.

Civil enforcement in federal court is not a clean solution either. It can take years, it depends on judges who are often reluctant to referee political disputes, and it still requires Congress to outsource its own constitutional authority to another branch. Inherent contempt, by contrast, was designed to let the legislature enforce its own will.

The objection and the answer

The main objection to inherent contempt is easy to understand: a legislature that can lock people up sounds dangerous. But that objection usually ignores the historical limits on the power. Inherent contempt is not criminal punishment. It is a civil, coercive measure that ends the moment the witness complies or the legislative session ends. It requires a vote of the full House or Senate, which means it cannot be done quietly by a committee chairman or a staff member. And the courts retain the power to review the detention through habeas corpus.

I would go further. If Congress revives inherent contempt, it should do so with explicit due process protections: a recorded floor vote, written notice to the witness, an opportunity to comply before any arrest, and strict limits on the duration and conditions of detention. That is not a retreat from the power. It is the original limit on the power.

What is far more dangerous is the current arrangement, in which Congress has the constitutional duty to investigate but no independent means to enforce its subpoenas. Every executive branch official now knows that defying Congress carries no meaningful consequence if the president's own Justice Department decides not to act. As Thomas Sowell has spent a career demonstrating, incentives matter. If the cost of stonewalling is close to zero, stonewalling is what you get.

Why this matters beyond Washington

This is not just a procedural fight among politicians. The ordinary citizen has an interest in a legislature that can actually check the executive branch and the administrative state. Congress has handed enormous lawmaking power to federal agencies, bureaucrats who are not on the ballot and who answer to no voter. The only way the people's representatives can know what those agencies are doing is through oversight. If the executive branch can refuse to cooperate and suffer no independent consequence, the constitutional chain of accountability is broken.

Reclaiming inherent contempt is not about jailing political opponents. It is about restoring the constitutional republic. The Framers did not design a system in which the legislature must ask the executive for permission to do its job. They designed a system of rival powers. As Madison wrote in Federalist 51, ambition must be made to counteract ambition. That requires each branch to defend its own powers, not surrender them for the sake of convenience or temporary comity.

Congress has the power. It always has. The problem is not the Constitution. It is a modern legislature that has forgotten that a power unused is a power lost, and that a government of separated powers cannot function when one branch voluntarily disarms itself.
