Federal habeas corpus comes in two principal forms: 28 U.S.C. § 2255 (motion to vacate, set aside, or correct sentence) filed in the sentencing court, and 28 U.S.C. § 2241 (habeas corpus) filed in the district of confinement. § 2255 reaches constitutional errors, jurisdictional defects, and ineffective assistance of counsel. § 2241 reaches BOP computation, FSA credits, halfway house, and execution-of-sentence challenges.
§ 2255 — motion to vacate, set aside, or correct sentence
The 28 U.S.C. § 2255 motion is the principal federal collateral-attack vehicle. Filed in the sentencing court within one year of finality, it raises constitutional errors, jurisdictional defects, and ineffective assistance of counsel claims.
28 U.S.C. § 2255 authorizes a federal prisoner to move the sentencing court to vacate, set aside, or correct the sentence when (a) the sentence was imposed in violation of the Constitution or laws of the United States; (b) the court was without jurisdiction; (c) the sentence exceeds the maximum authorized; or (d) the sentence is otherwise subject to collateral attack. § 2255 is the exclusive remedy for these challenges to the conviction or sentence itself — § 2241 cannot substitute.
The motion is filed in the sentencing court, before the original sentencing judge if still available. Common grounds include: ineffective assistance of counsel (the most common ground, evaluated under Strickland v. Washington, 466 U.S. 668 (1984)); newly discovered evidence; prosecutorial misconduct affecting the verdict; constitutional defects in the plea or trial; sentencing errors that violate the Constitution or render the sentence unlawful.
The Antiterrorism and Effective Death Penalty Act of 1996 (AEDPA) imposes substantial procedural restrictions on § 2255 motions: a one-year statute of limitations under § 2255(f); successive-motion restrictions under § 2255(h); restrictions on evidentiary hearings; deferential review of state-court factual determinations (relevant where related state proceedings exist).
AEDPA one-year limitations
§ 2255 motions must be filed within one year of finality of the conviction (or specified later trigger events). AEDPA's strict timeliness rules are enforced vigorously, with limited equitable-tolling availability.
§ 2255(f) requires that motions be filed within one year of the latest of: (1) the date the judgment of conviction becomes final; (2) the date the impediment to filing created by governmental action is removed; (3) the date the right asserted was initially recognized by the Supreme Court and made retroactive on collateral review; or (4) the date the facts supporting the claim could have been discovered through the exercise of due diligence.
"Final" for purposes of § 2255(f)(1) means after direct appeal is exhausted. If no direct appeal was filed, the conviction becomes final 14 days after entry of judgment (when the time for filing notice of appeal expired). If direct appeal was filed and denied, finality runs from the denial of the petition for writ of certiorari to the Supreme Court (or expiration of the time to file the petition).
Equitable tolling is available in narrow circumstances under Holland v. Florida, 560 U.S. 631 (2010) — typically requiring (a) the defendant pursued his rights diligently and (b) extraordinary circumstances beyond his control prevented timely filing. Counsel's misadvice about the deadline, mental incapacity, language barriers, or active fraud by counsel may support equitable tolling on a case-specific showing.
Successive motions and the gatekeeper procedure
A defendant generally gets one § 2255 motion. Second or successive motions require pre-filing authorization from the court of appeals based on (a) newly discovered evidence establishing innocence or (b) a new retroactive constitutional right.
§ 2255(h) restricts second-and-successive motions: a successive motion is authorized only if it contains either (1) newly discovered evidence that, if proven and viewed in light of the evidence as a whole, would be sufficient to establish by clear and convincing evidence that no reasonable factfinder would have found the movant guilty; or (2) a new rule of constitutional law, made retroactive to cases on collateral review by the Supreme Court, that was previously unavailable.
The defendant must obtain authorization from the court of appeals before filing a successive § 2255 in the district court. The application to the court of appeals is governed by § 2244(b)(3). Denial of authorization is not reviewable by certiorari. Authorization is rare — most second-or-successive applications are denied.
The interaction between § 2255 and prior § 2255 motions can be intricate when subsequent events expand the law (e.g., Supreme Court decisions creating new rights). Defense counsel evaluating successive-motion possibilities must analyze: (a) whether the new ground existed at the time of the prior motion; (b) whether the Supreme Court has made the rule retroactive on collateral review (typically requiring an explicit holding); (c) whether the proposed claim, if accepted, would result in a different outcome.
§ 2241 — BOP computation, halfway house, FSA credits
28 U.S.C. § 2241 habeas in the district of confinement is the proper vehicle to challenge BOP's execution of the sentence — good-time computations, FSA-credit application, halfway-house decisions, programming eligibility, security-classification disputes.
28 U.S.C. § 2241 authorizes a federal prisoner to bring habeas corpus when held "in custody in violation of the Constitution or laws or treaties of the United States." § 2241 is the proper vehicle for execution-of-sentence challenges — challenges to BOP's computation or implementation of a sentence that the sentencing court properly imposed. Common subjects: good-time credit computation, FSA earned-time credit application, halfway-house and home-confinement decisions, programming eligibility, security-level designations, disciplinary findings reducing time credit, parole determinations (where applicable to pre-1987 sentences).
§ 2241 is filed in the district of confinement — the district where the federal facility holding the defendant is located, not the sentencing district. For defendants in TXND/TXED, common districts include the district where FMC Carswell (Fort Worth — TXND), FCI Seagoville (TXND), FCI Fort Worth (TXND), or FCI Bastrop (TXED Western Division) is located. The defendant typically must exhaust BOP administrative remedies under 28 C.F.R. § 542 before filing.
Standard of review on § 2241 challenges depends on what BOP did. BOP regulations and policy statements are entitled to Chevron deference in some areas; sentence-computation rules under 18 U.S.C. § 3624(b) and § 3585(b) are largely mechanical and reviewed for compliance with the statutory text. FSA credit issues have generated substantial litigation since 2018; defense counsel often needs to engage BOP's Designation and Sentence Computation Center (DSCC) and document the precise computational dispute.

FAQ
What is the practical importance of this topic in a federal case?
Federal criminal practice is governed by precise procedural rules, and the topic of habeas corpus is a recurring high-stakes decision point. Failure to handle the procedural step correctly can result in waiver of significant rights or loss of strategic position. Defense counsel familiar with federal practice navigates these decisions routinely; defendants without counsel routinely make procedural missteps that affect the case outcome.
Does this topic apply in both the Northern and Eastern Districts of Texas?
Yes. The Federal Rules of Criminal Procedure and the U.S. Code apply uniformly across federal districts, including the U.S. District Court for the Northern District of Texas (TXND, headquartered in Dallas and Fort Worth) and the U.S. District Court for the Eastern District of Texas (TXED, with the Sherman division covering Collin, Denton, and Grayson counties). Local rules and individual judge practices vary, but the substantive framework is the same.
Should I retain counsel specifically for this phase?
Yes, in almost all cases. Federal criminal practice is a specialized field — substantively distinct from state practice, with different rules, deadlines, and strategic considerations. Counsel admitted to practice in TXND, TXED, and the Fifth Circuit (and ideally with experience in the type of offense charged) is the appropriate choice. Local state-court practitioners without federal-court admission cannot appear in federal cases.
