Habeas corpus is a very old court order that makes the government prove it is holding someone legally. For people serving a federal sentence, the § 2255 motion — a request asking the judge who sentenced you to throw out or fix the sentence — is the modern form of that order.
The “Great Writ” is a cornerstone of American law. The Framers thought it was so important that they protected it in the body of the Constitution, before there was a Bill of Rights.
The Suspension Clause, in Article I, Section 9, says: “[t]he privilege of the Writ of Habeas Corpus shall not be suspended, unless when in cases of Rebellion or Invasion the public Safety may require it.”
Later on this page we explain how the Antiterrorism and Effective Death Penalty Act of 1996 (AEDPA) made habeas cases much harder, including by adding a one-year deadline.
Why did the founders care so much about habeas corpus?
Alexander Hamilton explained why the writ matters in The Federalist No. 84:
“[T]he practice of arbitrary imprisonments, have been, in all ages, the favorite and most formidable instruments of tyranny. The observations of the judicious [William] Blackstone . . . are well worthy of recital: ‘To bereave a man of life . . . or by violence to confiscate his estate, without accusation or trial, would be so gross and notorious an act of despotism as must at once convey the alarm of tyranny throughout the whole nation; but confinement of the person, by secretly hurrying him to jail, where his sufferings are unknown or forgotten, is a less public, a less striking, and therefore a more dangerous engine of arbitrary government.’ And as a remedy for this fatal evil he is everywhere peculiarly emphatical in his encomiums on the habeas corpus act [of 1679], which in one place he calls ‘the bulwark of the British Constitution.'”
The writ is a bulwark of the U.S. Constitution too. Justice Kennedy wrote that the Suspension Clause “ensures that, except during periods of formal suspension, the Judiciary will have a time tested device, the writ, to maintain the ‘delicate balance of governance’ that is itself the surest safeguard of liberty.”
He added that the Clause “protects the rights of the detained by affirming the duty and authority of the Judiciary to call the jailer to account.” Boumediene v. Bush, 553 U.S. 723, 745 (2008).
How did federal habeas corpus become the § 2255 motion?
Habeas law grew over several centuries, so it is complicated. Here are the main steps in the United States:
- 1789: The Judiciary Act first gave federal courts the power to issue the writ.
- 1867: Congress extended federal habeas corpus to state prisoners.
- 1948: Congress passed 28 U.S.C. § 2255 for federal prisoners. It gives them a remedy as broad as habeas corpus, but they file it in the court that sentenced them instead of the court where they are held. United States v. Hayman, 342 U.S. 205 (1952).
Under § 2255, a federal prisoner can ask the court to vacate, set aside, or correct a sentence on the grounds that “the sentence was imposed in violation of the Constitution or laws of the United States, or that the court was without jurisdiction to impose such sentence, or that the sentence was in excess of the maximum authorized by law, or is otherwise subject to collateral attack.” 28 U.S.C. § 2255(a).
How did the AEDPA change § 2255?
The Antiterrorism and Effective Death Penalty Act of 1996 (AEDPA) made § 2255 cases much harder for people without a lawyer — and for many lawyers too. It made three big changes:
- A one-year deadline to file the motion. 28 U.S.C. § 2255(f).
- A “certificate of appealability” — permission you must get before you can appeal a denial. 28 U.S.C. § 2253(c).
- Strict limits on a second or later § 2255 motion. 28 U.S.C. § 2255(h).
Why § 2255 instead of a traditional habeas petition?
Before 1948, federal prisoners often sought the writ where they were confined. That burdened districts that house large prisons and complicated review of the trial record. Section 2255 channels the challenge to the sentencing court, which already has the criminal file. The Supreme Court upheld that design and treated § 2255 as a remedy as broad as habeas corpus for federal prisoners. United States v. Hayman, 342 U.S. 205 (1952).
Traditional habeas under 28 U.S.C. § 2241 still matters in limited settings — for example, some challenges to the execution of a sentence, or claims that fit the savings clause when § 2255 is inadequate or ineffective. Most attacks on the validity of a federal conviction or sentence belong in § 2255 first.
What AEDPA means in day-to-day practice
The 1996 amendments did not repeal the writ, but they changed how federal post-conviction cases run. The one-year limit in § 2255(f), the certificate-of-appealability requirement in § 2253(c), and the gatekeeping rules for second or successive motions in § 2255(h) are the three features people encounter most often. Missing any one of them can end a case even when the underlying claim has force.
Those rules are why preparation, calendaring, and careful pleading matter as much as the legal theory. The history of the writ explains why the remedy exists; the AEDPA provisions explain why the path is narrow.
Common questions
What is habeas corpus?
Habeas corpus is Latin for “you have the body.” It is a court order, rooted in English common law, that brings a challenge to someone’s confinement before a judge. Federal courts can issue it under 28 U.S.C. § 2241 and the sections that follow.
People in federal custody who want to challenge the conviction or sentence itself generally use 28 U.S.C. § 2255 instead.
Where is the motion explained?
The 2255 motion page explains the request Congress created in 1948 and the grounds in 28 U.S.C. § 2255(a). This page is the history of how habeas corpus became that motion. You file it with the court that sentenced you.
Aside from a direct appeal, how can I challenge my sentence?
After the appeal is over (or the time to appeal has passed), a federal prisoner can challenge the conviction or sentence with a § 2255 motion.
There are limits. A claim that could have been raised on direct appeal but was not is usually “procedurally defaulted” — blocked — unless you can show cause and prejudice or actual innocence. Bousley v. United States, 523 U.S. 614, 622 (1998). Claims that your lawyer was ineffective are the big exception: they can be raised for the first time in a § 2255 motion. Massaro v. United States, 538 U.S. 500, 504 (2003).
There are still many grounds a § 2255 motion can raise. Because the rules are strict, it is wise to talk with a lawyer who handles federal habeas cases before you file.
What does the AEDPA have to do with my section 2255 motion?
The AEDPA was signed into law on April 24, 1996. Most importantly, it added a one-year deadline to file a § 2255 motion. It also limits appeals in § 2255 cases and makes a second or later § 2255 motion very hard to file.
