What is AEDPA, and how does it affect a federal prisoner?
AEDPA is the Antiterrorism and Effective Death Penalty Act of 1996, Pub. L. 104-132, 110 Stat. 1214, enacted April 24, 1996. For a federal prisoner it imposed three restrictions on 28 U.S.C. §2255: a one-year limitation period in §2255(f), a two-ground gate on second or successive motions in §2255(h), and a certificate-of-appealability requirement in §2253(c).

Key takeaways on AEDPA
- Before 1996 there was no deadline. The Advisory Committee Note to Rule 9 of the Rules Governing §2255 Proceedings records the prior text: §2255 “specifically provides that ‘a motion for such relief may be made at any time.'” AEDPA replaced that with one year.
- AEDPA’s three §2255 restrictions are §2255(f), §2255(h), and §2253(c). Everything else commonly attributed to AEDPA — the §2254(d) deference standard, the §2254(e)(2) hearing bar, the §2244(b) gatekeeping criteria, the exhaustion rules — governs state prisoners under §2254.
- §2254(d) does not apply to your §2255 motion. By its own terms it governs “a person in custody pursuant to the judgment of a State court.” There is no federal-prisoner counterpart, and the “unreasonable application of clearly established Federal law” language does not describe the standard a district court applies to a §2255 claim.
- The first §2255 motion is effectively the only one. Section 2255(h) permits a second one on two grounds only, and Jones v. Hendrix, 599 U.S. 465 (2023), holds that a prisoner who cannot satisfy them cannot route the claim into §2241 instead.
- Bowe v. United States, 607 U.S. 13 (2026), did not loosen §2255(h). It held that two provisions of §2244(b) — the certiorari bar in (b)(3)(E) and the old-claim bar in (b)(1) — reach only state prisoners. The two-condition gate in §2255(h) is untouched.
- AEDPA has survived Suspension Clause challenge. Felker v. Turpin, 518 U.S. 651 (1996), decided months after enactment, held the successive-petition restrictions “do not amount to a ‘suspension’ of the writ contrary to Article I, §9.”
What is AEDPA?
AEDPA is a 1996 federal statute — the Antiterrorism and Effective Death Penalty Act of 1996, Pub. L. 104-132, 110 Stat. 1214, approved April 24, 1996 — whose Title I rewrote federal habeas corpus and federal post-conviction procedure. The name covers more subjects than habeas; the habeas provisions are the part that matters to anyone challenging a conviction, and they are the only part this page addresses.
The Act worked by amendment rather than by creating a new chapter. Section 105 of Title I amended 28 U.S.C. §2255 itself, at 110 Stat. 1220 — that is where the one-year limitation and the successive-motion certification requirement came from. Other sections amended 28 U.S.C. §2244 and §2254 for state prisoners and §2253 for appeals, and section 107 added an entirely new chapter 154 governing capital cases in qualifying states.
Because AEDPA amended existing statutes, you will rarely see “AEDPA” cited in a court order. What you will see is a citation to §2255(f), §2255(h), or §2253(c) — the codified provisions the Act created. When a district court writes that a motion is “time-barred under AEDPA,” it means §2255(f). When a court of appeals writes that it lacks authorization “under AEDPA,” it means §2255(h). Recognizing that translation is most of what a reader needs.
Habeas corpus itself long predates the Act; what habeas corpus means and where the writ comes from is covered on its own page, and what §2255 says, subsection by subsection, on another. AEDPA did not create the remedy. It put deadlines and gates on it.
Before and after AEDPA: what the Act actually changed
The table below is the whole Act as it bears on collateral review, restriction by restriction. The right-hand column is the part most sources omit — whether the restriction reaches a federal prisoner filing under §2255, or only a state prisoner filing under §2254.
AEDPA’s habeas restrictions: the provision created, the prior law, and who it reaches
| Restriction AEDPA added | Provision it created | What the law was before April 24, 1996 | Does it apply to a federal prisoner’s §2255 motion? |
|---|---|---|---|
| One-year limitation period, running from the latest of four trigger dates | 28 U.S.C. §2255(f) | No limitation period. Section 2255 provided that “a motion for such relief may be made at any time.” | Yes. This is the deadline that decides most §2255 cases. |
| One-year limitation period for state prisoners | 28 U.S.C. §2244(d) | No limitation period | No — §2244(d) governs §2254 applications. |
| Second or successive motion must be certified in advance by a three-judge panel of the court of appeals, on two grounds only | 28 U.S.C. §2255(h) | Judge-made abuse-of-the-writ doctrine, applied case by case; no advance appellate authorization requirement | Yes. Newly discovered evidence meeting a clear-and-convincing innocence standard, or a new retroactive rule of constitutional law. |
| Gatekeeping criteria and authorization procedure for successive state petitions, including the 30-day decision deadline | 28 U.S.C. §2244(b)(1)–(3) | Abuse-of-the-writ doctrine | Partly. Section 2255(h) incorporates §2244’s certification procedure only. Under Bowe (2026), §2244(b)(1)’s old-claim bar and §2244(b)(3)(E)’s certiorari bar do not reach federal prisoners. |
| Certificate of appealability required before appealing a denial, issued only on “a substantial showing of the denial of a constitutional right” | 28 U.S.C. §2253(c) | A certificate of probable cause, and no certificate requirement at all for a §2255 appeal | Yes. Section 2253(c)(1)(B) names “the final order in a proceeding under section 2255” expressly. |
| Deference to state-court merits adjudications — relief barred unless the decision was “contrary to, or involved an unreasonable application of, clearly established Federal law” | 28 U.S.C. §2254(d) | Federal courts reviewed federal constitutional questions independently | No. By its terms it governs only “a person in custody pursuant to the judgment of a State court.” |
| Bar on federal evidentiary hearings where the applicant failed to develop the facts in state court | 28 U.S.C. §2254(e)(2) | Hearings governed by Townsend-era standards and the pre-1996 version of §2254(d) | No. Hearings in §2255 cases are governed by §2255(b) and Rule 8 of the Rules Governing §2255 Proceedings. |
| Capital-case fast track for qualifying states: a 180-day filing period and expedited review | 28 U.S.C. ch. 154 (§§2261–2266) | No separate capital track | No — chapter 154 applies to §2254 applications in opt-in states. |

What is the AEDPA deadline?
For a federal prisoner, the AEDPA deadline is the one-year period in 28 U.S.C. §2255(f). The statute reads: “A 1-year period of limitation shall apply to a motion under this section. The limitation period shall run from the latest of—” and then lists four dates:
- the date on which the judgment of conviction becomes final;
- the date on which an unconstitutional governmental impediment to making a motion is removed, if the movant was prevented from filing by it;
- the date on which the right asserted was initially recognized by the Supreme Court, if that right has been newly recognized and made retroactively applicable to cases on collateral review; or
- the date on which the facts supporting the claim could have been discovered through the exercise of due diligence.
Three features of that structure cause most of the confusion. First, the operative word is latest — not “earliest,” and not “whichever the court prefers.” Second, the four triggers are claim-specific, so a motion raising several claims can have several different start dates, and a filing that is timely as to one claim can be untimely as to another. Third, §2255(f)(3) runs from the date the Supreme Court recognized the right, not from a later decision holding it retroactive — a distinction that has cost many movants their motion.
Nothing in §2255(f) is tolled by filing something else. A pending compassionate release motion, a pending administrative remedy, or a pending Rule 33 motion does not stop the year. The computation itself, date by date, belongs to the §2255 statute of limitations page, and the doctrine that can occasionally excuse a late filing belongs to equitable tolling.
Applied Insight — Elizabeth Franklin-Best, Esq., Principal Attorney: When a §2255 file comes in, we compute all four §2255(f) dates separately before we form any view of the merits, and we do it claim by claim rather than for the motion as a whole. The reason is that §2255(f)(3) and §2255(f)(4) frequently produce a later date than finality for one specific claim — a new Supreme Court right, or a fact that emerged from a co-defendant’s later proceeding — while every other claim in the same motion still runs from finality. Pleading that structure explicitly, with the date and the supporting basis stated for each claim, is how a timeliness objection is answered before it is raised.
Why can I only file one §2255?
Because 28 U.S.C. §2255(h) permits a second one on two grounds only, and requires advance permission from the court of appeals before the district court may even consider it. The provision reads that “[a] second or successive motion must be certified as provided in section 2244 by a panel of the appropriate court of appeals to contain—” 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 of the offense; or (2) a new rule of constitutional law, made retroactive to cases on collateral review by the Supreme Court, that was previously unavailable.”
The Supreme Court described those in Jones v. Hendrix as “the two limited conditions in which federal prisoners may bring second or successive collateral attacks on their sentences,” and in Bowe v. United States as the “two—and only two—conditions in which a second or successive §2255 motion may proceed.”
Notice what is not on the list. A change in how a court of appeals reads a criminal statute is not a new rule of constitutional law — and whether a given Supreme Court decision is both new, constitutional, and made retroactive on collateral review is itself a contested question. Newly discovered evidence that undermines a sentencing enhancement, rather than guilt of the offense, does not meet §2255(h)(1); the innocence showing that provision demands is discussed on actual innocence. Ineffective assistance discovered after the first motion does not qualify unless it fits one of the two. The gate is narrow by design.
The procedure comes from §2244(b)(3): the movant moves in the court of appeals for an order authorizing the district court to consider the motion; a three-judge panel decides; the panel may authorize only on a prima facie showing; and it is to rule “not later than 30 days after the filing of the motion.” Rule 9 of the Rules Governing §2255 Proceedings states the same requirement from the movant’s side. How the gate operates in practice is covered on second or successive 2255.
The operational consequence is the most important thing on this page after the deadline: the first §2255 motion is, for practical purposes, the only one. A motion that omits a viable claim, or pleads one in conclusory terms that draw a summary dismissal, usually forecloses that claim permanently rather than deferring it. That is why competent practice front-loads everything — full record acquisition, investigation, and every developed claim in a single filing. It is also why an appeal waiver in a plea agreement deserves careful reading before the first motion is drafted rather than after the government invokes it: the waiver operates on top of AEDPA’s gates, not instead of them.
What Bowe v. United States changed — and what it did not
Bowe v. United States, 607 U.S. 13 (2026), decided January 9, 2026, is the newest AEDPA decision and the one most likely to be misdescribed. It is worth stating its holding and its limit in the same paragraph.
What it held. Two provisions of §2244(b) do not reach federal prisoners. The certiorari bar in §2244(b)(3)(E) does not bar Supreme Court review of a court of appeals’ denial of authorization to a federal prisoner, so the Court has jurisdiction to review such a denial. And §2244(b)(1)’s “old-claim bar” — requiring dismissal of a claim “presented in a prior application” — likewise reaches only state prisoners, because its text refers expressly to “a second or successive habeas corpus application under section 2254.” The reasoning is textual: §2255(h)’s cross-reference “incorporates only the provisions in §2244 that ‘provid[e]’ for how a ‘panel of the appropriate court of appeals’ ‘certifie[s]’ a second or successive filing,” and the certiorari bar “is not one of those provisions.”
What it did not hold. Bowe did not remove the second-or-successive restrictions, did not lower the §2255(h) threshold, and did not create a new route to filing again. The two conditions in §2255(h) are exactly what they were on January 8, 2026. Any description of Bowe as having “opened up” successive motions is wrong.
A Seventh Circuit judge has said so in chambers. In Upchurch v. United States, No. 26-1114 (7th Cir. Aug. 4, 2026) (Brennan, C.J., in chambers), the judge concluded that the bar on petitions for rehearing in the same subparagraph still applies to federal prisoners, explaining that “[a]t several points, the majority opinion noted that its holding was limited to the certiorari bar alone,” and that “Bowe does not upset the longstanding consensus in the federal courts of appeals on this issue.” A movant in the Middle District of Florida advanced the broader reading in United States v. Handlon, No. 2:13-cr-00145 (M.D. Fla. Aug. 20, 2026), and it did not succeed.
The accurate way to use Bowe is narrow and real: if a court of appeals denies authorization by applying the wrong statutory criteria — for example, by importing §2244(b)(1) or §2244(b)(2) standards into a federal prisoner’s application — that denial is now reviewable on certiorari. That is a meaningful change at the margin of a gate that otherwise stands where it stood.
Is the §2254(d) deference standard relevant to my §2255?
No. This is the most consequential thing on the page, and it is the reason most AEDPA material misleads federal prisoners.
Section 2254(d) provides that “[a]n application for a writ of habeas corpus on behalf of a person in custody pursuant to the judgment of a State court shall not be granted with respect to any claim that was adjudicated on the merits in State court proceedings unless the adjudication of the claim— (1) resulted in a decision that was contrary to, or involved an unreasonable application of, clearly established Federal law, as determined by the Supreme Court of the United States; or (2) resulted in a decision that was based on an unreasonable determination of the facts in light of the evidence presented in the State court proceeding.” The emphasized clause is the whole answer: the provision is addressed to persons in state custody, and it exists because federal review of a state judgment raises comity concerns that federal review of a federal judgment does not.
There is no §2255 counterpart. Section 2255 contains no deference provision, and there is no prior state-court adjudication to defer to — the court hearing the §2255 motion is the same court that entered the judgment.
The Supreme Court confirmed the structural premise in Bowe, reading Congress’s word choices as deliberate: “Elsewhere in this very section, Congress expressly distinguishes §2254 ‘applications’ from §2255 ‘motions.’ §2266(a); see also §§2253(c)(1)(A)–(B) (distinguishing state habeas proceedings from proceedings under §2255).”
Two practical consequences. First, if you are reading a habeas treatise, a §2254 opinion, or an online guide that turns on “unreasonable application of clearly established Federal law,” you are reading about a standard that will not be applied to your motion. Second, the phrase “doubly deferential” — which appears constantly in ineffective-assistance discussions — describes the combination of Strickland’s deference to counsel with §2254(d)’s deference to the state court. In a §2255 case only the first half of that pair is in play. Which system governs your case is decided on §2254 or §2255.
Applied Insight — Elizabeth Franklin-Best, Esq., Principal Attorney: A reliable tell in any habeas material is whether the author says “petitioner” or “movant,” and whether the deadline is described as running from the end of state review. Both signal §2254 practice. When a prospective client sends us a draft motion built around “unreasonable application of clearly established Federal law,” the substantive claim is often sound and the framing has to be rebuilt from the ground up — the argument a federal district court needs on a §2255 motion is that the judgment is unlawful, not that some earlier court was unreasonable in saying otherwise. Sorting that out before a motion is filed matters more than usual here, because §2255(h) means the filing will not get a second draft.
What AEDPA did not do is equally worth naming. It did not create the requirement that a claim be raised on direct appeal or be defaulted — procedural default is judge-made doctrine that predates 1996 and survives it. It did not narrow the four grounds in §2255(a). And it did not change who may bring a §2255 motion. Those limits come from the statute’s own structure and from case law, not from the 1996 amendments, which is why an argument that “AEDPA bars my claim” is often really an argument about default or cognizability wearing the wrong label.
§2254(e)(2) and the evidentiary-hearing contrast
AEDPA also restricted federal evidentiary hearings for state prisoners, in §2254(e)(2): if the applicant “has failed to develop the factual basis of a claim in State court proceedings, the court shall not hold an evidentiary hearing on the claim unless” the claim relies on a new retroactive constitutional rule or a previously undiscoverable factual predicate, and the underlying facts would establish by clear and convincing evidence that but for constitutional error no reasonable factfinder would have found the applicant guilty.
That is an extraordinarily high bar, and the Supreme Court tightened it further in Shinn v. Martinez Ramirez, 596 U.S. 366 (2022), holding that “under §2254(e)(2), a federal habeas court may not conduct an evidentiary hearing or otherwise consider evidence beyond the state-court record based on the ineffective assistance of state postconviction counsel.”
None of that governs a §2255 motion. The §2255 hearing standard comes from the statute itself and from the Rules. Section 2255(b) directs that “[u]nless the motion and the files and records of the case conclusively show that the prisoner is entitled to no relief, the court shall … grant a prompt hearing thereon, determine the issues and make findings of fact and conclusions of law.” Rule 6 permits discovery for good cause, Rule 7 permits the record to be expanded with affidavits and documents, and Rule 8(c) provides that if a hearing is warranted “the judge must appoint an attorney to represent a moving party who qualifies to have counsel appointed under 18 U.S.C. §3006A.”
The difference is not cosmetic. A federal prisoner developing an off-record claim — an uninvestigated alibi, an unconveyed plea offer, a conflict — is operating under a framework that contemplates factual development, not one designed to foreclose it. That is also why a claim of ineffective appellate counsel or conflict of interest by trial counsel is properly a §2255 claim rather than an appellate one. Whether a hearing will actually be held is covered on 2255 evidentiary hearing.
The certificate of appealability: §2253(c)
AEDPA also changed what happens after a §2255 motion is denied. Section 2253(c)(1) provides that “[u]nless a circuit justice or judge issues a certificate of appealability, an appeal may not be taken to the court of appeals from … (B) the final order in a proceeding under section 2255.” Section 2253(c)(2) sets the standard: a certificate “may issue under paragraph (1) only if the applicant has made a substantial showing of the denial of a constitutional right.” Section 2253(c)(3) adds that the certificate “shall indicate which specific issue or issues satisfy the showing required by paragraph (2).”
Three consequences follow, and they surprise people. There is no appeal as of right from a §2255 denial. The showing is expressly constitutional, so a purely statutory or Guidelines claim may be unappealable even if it was the strongest claim in the motion. And the certificate is issue-specific, so a partial grant limits the appeal to the issues named.
Rule 11(a) of the Rules Governing §2255 Proceedings adds the timing: “[t]he district court must issue or deny a certificate of appealability when it enters a final order adverse to the applicant,” and if the district court denies one, “a party may not appeal the denial but may seek a certificate from the court of appeals under Federal Rule of Appellate Procedure 22.” A motion to reconsider a denial does not extend the time to appeal. The standard itself, and how it is briefed, belong to certificate of appealability; the sequence of events that leads there is on what happens after filing a 2255.
Chapter 154: the capital-case fast track
Section 107 of AEDPA added a new chapter 154 to Title 28 — sections 2261 through 2266 — creating an accelerated federal review track for capital cases from states that qualify by establishing a mechanism for appointing and compensating competent post-conviction counsel. Its centerpiece is a shortened limitation period: under 28 U.S.C. §2263(a), an application “must be filed in the appropriate district court not later than 180 days after final State court affirmance of the conviction and sentence on direct review or the expiration of the time for seeking such review,” subject to tolling for certiorari proceedings, for a first state post-conviction petition, and for up to 30 additional days on a good-cause showing.
Chapter 154 applies to §2254 applications by state capital prisoners in opt-in states. It does not apply to a federal prisoner’s §2255 motion, whether or not the federal case is capital. It is included here because it is a substantial part of what AEDPA did, and because it explains the Act’s name: the statute’s habeas title was drafted with capital litigation prominently in view, which is why so much of the surrounding commentary is about death-penalty procedure rather than about the ordinary §2255 motion most readers are actually facing.
How the Rules Governing §2255 Proceedings responded
The Rules Governing Section 2255 Proceedings were amended after 1996 to absorb the Act, and the Advisory Committee said why. The note to Rule 3(b) is explicit: “Before the adoption of a one-year statute of limitations in the Antiterrorism and Effective Death Penalty Act of 1996, 110 Stat. 1214, the moving party suffered no penalty, other than delay, if the petition was deemed insufficient.” Because a dismissal now “may pose a significant penalty for a moving party who may not be able to file a corrected motion within the one-year limitation period,” Rule 3(b) requires the clerk to file a motion even if it fails to comply with Rule 2’s form requirements, and the movant is then directed to submit a corrected version.
That is a genuinely protective rule and it is not widely known. A defective motion filed inside the year is filed; it does not bounce. Rule 3(d) supplies a second protection of the same kind, treating a motion by an inmate confined in an institution as filed when deposited in the institution’s internal mailing system — the prisoner mailbox rule. Both rules exist because AEDPA made the consequence of a day’s slippage permanent. The rest of the filing mechanics are on how to file a 2255 motion.
Rule 9 was rewritten to carry the new gate: “Before presenting a second or successive motion, the moving party must obtain an order from the appropriate court of appeals authorizing the district court to consider the motion, as required by 28 U.S.C. §2255, para. 8.” The same rule’s Advisory Committee Note preserves the pre-AEDPA text for anyone who wants to see the change in the Committee’s own words — “§ 2255 specifically provides that ‘a motion for such relief may be made at any time.'” And Rule 11 was added to require the district court to issue or deny a certificate of appealability at the moment it enters a final adverse order, rather than leaving the question to a later motion.
Jones v. Hendrix: the current endpoint of AEDPA’s restrictions
For twenty-seven years after AEDPA, most circuits treated the saving clause in 28 U.S.C. §2255(e) as a pressure valve. If a prisoner had a claim that an intervening decision interpreting a criminal statute made his conduct non-criminal, and §2255(h) foreclosed a second motion because the claim was statutory rather than constitutional, several circuits allowed the claim to proceed under §2241 instead.
Jones v. Hendrix, 599 U.S. 465 (2023), ended that. The Court held: “Section 2255(e) does not allow a prisoner asserting an intervening change in interpretation of a criminal statute to circumvent the Antiterrorism and Effective Death Penalty Act of 1996’s (AEDPA) restrictions on second or successive §2255 motions by filing a §2241 habeas petition.” And it stated the consequence without softening it: “The inability of a prisoner with a statutory claim to satisfy §2255(h) does not mean that the prisoner may bring the claim in a §2241 petition.”
What the saving clause still preserves is narrow: recourse to §2241 “in cases where unusual circumstances make it impossible or impracticable to seek relief in the sentencing court, as well as for challenges to detention other than collateral attacks on a sentence.”
The decision is the endpoint of AEDPA’s restrictive arc because it forecloses the last widely used workaround. It also abrogated a body of circuit precedent that a great deal of published guidance still repeats as live law. The vehicle question, and what genuinely remains available under §2241, is worked through on whether to file under §2255 or §2241.
Has AEDPA been challenged as unconstitutional?
Yes, repeatedly, and the core challenges have failed. The Suspension Clause, U.S. Const. art. I, §9, provides that the privilege of the writ of habeas corpus shall not be suspended except in cases of rebellion or invasion. The argument has been that AEDPA’s successive-petition gate suspends the writ for prisoners who cannot get through it.
The Supreme Court rejected that within months of enactment. In Felker v. Turpin, 518 U.S. 651 (1996), the Court held that “[t]he new restrictions on successive petitions constitute a modified res judicata rule, a restraint on what is called in habeas corpus practice ‘abuse of the writ,'” that they are “well within the compass of this evolutionary process,” and that “they do not amount to a ‘suspension’ of the writ contrary to Article I, §9.” Felker also rejected an Article III Exceptions Clause challenge, reasoning that because AEDPA “does not repeal our authority to entertain a petition for habeas corpus,” it did not strip the Court of appellate jurisdiction.
One part of Felker has since been limited as applied to federal prisoners. Felker held that §2244(b)(3)(E) “prevents this Court from reviewing a court of appeals order denying leave to file a second habeas petition by appeal or by writ of certiorari.” That was a state-prisoner case, and Felker expressly did not address AEDPA’s application to §2255. Bowe (2026) now holds that the certiorari bar does not reach federal prisoners. The Suspension Clause holding is untouched.
The Court reaffirmed the point in Jones v. Hendrix, rejecting a Suspension Clause argument because it “would extend the writ of habeas corpus far beyond its scope when the Constitution was drafted and ratified.” Lower courts have followed: the Fourth Circuit in Bell v. Streeval, 147 F.4th 452 (4th Cir. 2025), applied its en banc holding in In re Vial that “the limitations imposed on second and successive §2255 motions by [§2255(h)] do not constitute a suspension of the writ.”
Why work with Elizabeth Franklin-Best, P.C.
Elizabeth Franklin-Best founded the firm in 2019 and practices federal criminal appeals and post-conviction relief nationwide on an intentionally small caseload. Over more than 20 years she has handled more than 330 federal proceedings, over 100 of them appeals, with sixteen published decisions as counsel of record. She is admitted to the U.S. Supreme Court and twelve of the thirteen U.S. Courts of Appeals — every regional circuit (1st–11th) plus the D.C. Circuit — and has appeared pro hac vice in federal courts from Montana to Florida. She is recognized by Best Lawyers in America 2026 for Appellate Practice and ranked by Chambers USA 2026 for Litigation: White-Collar Crime & Government Investigations, was named South Carolina Public Defender of the Year in 2010, and is the author of Reversing Your Criminal Conviction: Develop Your Winning Strategy (2023).
AEDPA is not a topic the firm writes about academically. Its provisions are the operating constraints on every §2255 motion the firm files: which claims go in the first motion because there will not be a second, how each §2255(f) trigger date is pleaded, and whether the record supports a certificate of appealability if the motion is denied. Those decisions are made at the beginning of a case, not at the end. Working with a federal 2255 motion lawyer is largely a matter of getting them made early, and what a post-conviction attorney can still do after the appeal ends maps the remaining options against custody status and elapsed time.

Frequently Asked Questions About AEDPA
What is AEDPA?
AEDPA is the Antiterrorism and Effective Death Penalty Act of 1996, Pub. L. 104-132, 110 Stat. 1214, enacted April 24, 1996. Its Title I rewrote federal habeas corpus and federal post-conviction procedure by amending existing statutes rather than creating a new chapter. For federal prisoners, the provisions it created are 28 U.S.C. §2255(f), §2255(h), and §2253(c).
What did AEDPA change about habeas corpus?
AEDPA added deadlines and gates to a remedy that previously had neither. It created a one-year limitation period for both state prisoners (§2244(d)) and federal prisoners (§2255(f)), required advance court-of-appeals authorization for second or successive filings (§2244(b)(3), §2255(h)), required a certificate of appealability to appeal a denial (§2253(c)), imposed deference to state-court merits rulings (§2254(d)), restricted federal evidentiary hearings for state prisoners (§2254(e)(2)), and created a capital fast track in chapter 154.
Does AEDPA apply to a 2255 motion?
Yes — three of its restrictions apply directly. Section 2255(f) gives you one year from the latest of four trigger dates. Section 2255(h) permits a second or successive motion only on newly discovered evidence of innocence or a new retroactive rule of constitutional law, and only with advance authorization from a three-judge panel. Section 2253(c) requires a certificate of appealability before you can appeal a denial.
What is the AEDPA deadline?
For a federal prisoner it is the one year in 28 U.S.C. §2255(f), which runs from the latest of four dates: finality of the judgment; removal of an unconstitutional governmental impediment; the date the Supreme Court initially recognized a new right made retroactive on collateral review; or the date the supporting facts could have been discovered with due diligence. Different claims in one motion can run from different dates.
Is the 2254(d) deference standard relevant to my 2255?
No. Section 2254(d) applies by its own terms only to “a person in custody pursuant to the judgment of a State court,” and there is no §2255 counterpart. The “contrary to, or involved an unreasonable application of, clearly established Federal law” formula will not be applied to your motion. Guides built around that language are describing state-prisoner practice, not yours.
Why can I only file one 2255?
Because §2255(h) allows a second one on two grounds only — newly discovered evidence meeting a clear-and-convincing innocence standard, or a new rule of constitutional law made retroactive by the Supreme Court — and requires a three-judge panel of the court of appeals to authorize it first. Jones v. Hendrix (2023) confirmed that a prisoner who cannot meet those conditions cannot bring the claim under §2241 instead.
When was AEDPA passed?
AEDPA was enacted on April 24, 1996, as Pub. L. 104-132, 110 Stat. 1214. Section 105 of the Act amended 28 U.S.C. §2255 at 110 Stat. 1220, creating the one-year limitation period and the successive-motion certification requirement. Chapter 154’s capital provisions, added by section 107, apply to cases pending on or after that same date.
Has AEDPA been challenged as unconstitutional?
Yes, and the central challenges have failed. In Felker v. Turpin, 518 U.S. 651 (1996), the Supreme Court held that AEDPA’s successive-petition restrictions are a modified res judicata rule within the evolution of abuse-of-the-writ doctrine and “do not amount to a ‘suspension’ of the writ contrary to Article I, §9.” Jones v. Hendrix (2023) rejected a further Suspension Clause argument on historical grounds.
