28 U.S.C. § 2255 – Federal Post-Conviction Relief

The primary mechanism for challenging a federal conviction or sentence after direct appeal.

What § 2255 allows.
Section 2255 gives a person in federal custody the ability to ask the sentencing court to vacate, set aside, or correct a conviction or sentence through a post-conviction motion.

This statute replaces traditional habeas corpus for most federal prisoners and must be filed in the court that imposed the sentence.

Grounds for relief.
A § 2255 motion may be based on claims that:

  • The sentence was imposed in violation of the Constitution or federal law
  • The sentencing court lacked jurisdiction
  • The sentence exceeded the maximum authorized by law
  • The conviction or sentence is otherwise subject to collateral attack

Hearings and relief.
If the motion and record do not conclusively show that relief is unwarranted, the court must:

  • Notify the United States Attorney
  • Hold a hearing if necessary
  • Make findings of fact and conclusions of law

If relief is granted, the court may vacate the judgment, resentence the defendant, order a new trial, or otherwise correct the sentence.

One-year statute of limitations.
A § 2255 motion must generally be filed within one year of the latest of:

  • The date the conviction becomes final
  • The removal of an unconstitutional government impediment
  • A newly recognized, retroactive Supreme Court right
  • The discovery of new facts through due diligence

Successive motions.
Second or successive § 2255 motions are tightly restricted and require certification from the court of appeals based on:

  • New, compelling evidence of innocence, or
  • A new rule of constitutional law made retroactive by the Supreme Court

Relationship to habeas corpus.
Federal prisoners generally may not pursue habeas relief under § 2241 if § 2255 relief is available, unless the § 2255 remedy is shown to be inadequate or ineffective.
