The Last Train: Understanding Section 2255 and Federal Collateral Review
For a federal prisoner, the § 2255 motion is the last meaningful opportunity to correct a constitutional error. Here is how the procedural architecture actually works.

A motion to vacate, set aside, or correct a sentence under 28 U.S.C. § 2255 is the primary mechanism by which a federal prisoner challenges the validity of a conviction or sentence after the direct appeal has concluded. It is not a second appeal. It is a collateral remedy — narrow, procedurally complex, and unforgiving of mistakes. For the federal practitioner, understanding § 2255 is not optional. It is the difference between preserving a client's last meaningful remedy and losing it forever.
The statute authorizes relief on four grounds: the sentence was imposed in violation of the Constitution or laws of the United States; the court lacked jurisdiction; the sentence exceeded the maximum authorized by law; or the sentence is otherwise subject to collateral attack. 28 U.S.C. § 2255(a). The remedy, if granted, is not automatic release — the court may vacate the sentence and order a new trial, resentencing, or release, as appropriate.
The procedural hurdles are substantial. First, the one-year statute of limitations under the Antiterrorism and Effective Death Penalty Act of 1996 (AEDPA) runs from the latest of: the date the judgment becomes final; the date any government-created impediment is removed; the date the Supreme Court recognizes a new right made retroactive; or the date the facts supporting the claim could have been discovered through due diligence. 28 U.S.C. § 2255(f). Missing this deadline is fatal unless the movant can establish equitable tolling — a showing that requires both diligent pursuit of rights and extraordinary circumstances preventing timely filing. Holland v. Florida, 560 U.S. 631 (2010).
Second, procedural default. A claim that could have been raised on direct appeal but was not is barred from § 2255 review unless the movant shows cause for the default and actual prejudice from the error, or that a fundamental miscarriage of justice — typically, actual innocence — would result. United States v. Frady, 456 U.S. 152 (1982); Bousley v. United States, 523 U.S. 614 (1998). The cause-and-prejudice standard is rigorous. Ignorance of the law is not cause. Ineffective assistance of counsel, if established under Strickland v. Washington, 466 U.S. 668 (1984), is.
Third, the certificate of appealability. A § 2255 movant who loses in the district court cannot appeal as of right. The movant must obtain a certificate of appealability (COA) making "a substantial showing of the denial of a constitutional right." 28 U.S.C. § 2253(c)(2). The COA requirement is jurisdictional — without it, the court of appeals lacks authority to hear the appeal. Miller-El v. Cockrell, 537 U.S. 322 (2003).
Fourth, and most important: the bar on successive petitions. A prisoner gets one § 2255 motion as of right. A second or successive motion must be certified by the court of appeals to contain newly discovered evidence sufficient to establish by clear and convincing evidence that no reasonable factfinder would have convicted the movant, or a new rule of constitutional law made retroactive by the Supreme Court. 28 U.S.C. § 2255(h). In practice, this bar is nearly absolute. The first § 2255 motion is the last train out of the station.
