Writ of Coram Nobis: Relief After the Sentence Is Complete

By Elizabeth Franklin-Best, Esq., and Christopher Zoukis, JD, MBA

Can you challenge a conviction after the sentence is fully served?

Yes — if your federal sentence is completely over, a writ of error coram nobis under 28 U.S.C. § 1651(a) is the remaining federal judicial vehicle. You must show a fundamental error, continuing collateral consequences, sound reasons for the delay, and that no other remedy is available. It is filed in the court that convicted you.

Key takeaways on the writ of coram nobis

• Coram nobis exists only because § 2255 does not reach you. Section 2255(a) applies to “[a] prisoner in custody under sentence of a court established by Act of Congress.” United States v. Morgan, 346 U.S. 502 (1954), held that § 2255 is not a bar to coram nobis for a person no longer in custody.
• The power comes from the All Writs Act, not from a habeas statute. United States v. Denedo, 556 U.S. 904 (2009), confirms that “[i]n federal courts the authority to grant a writ of coram nobis is conferred by the All Writs Act.”
• Supervised release is custody. If you are still on supervision, coram nobis is unavailable and § 2255 is your vehicle — a rule the Ninth Circuit applied directly in Matus-Leva v. United States, 287 F.3d 758 (9th Cir. 2002).
• There is no statute of limitations, but delay is the most common reason petitions fail. Morgan requires “sound reasons” for not seeking relief earlier, and courts apply that seriously — the First Circuit reversed a grant on this ground in 2025.
• Continuing collateral consequences are an element, not background. Immigration status, professional licensure, firearm rights, and employment restrictions are the usual candidates, and circuits differ on how specific the showing must be.
• It is not expungement and it is not a pardon. Coram nobis vacates the conviction judicially; a pardon forgives punishment without erasing the record; equitable expungement of a valid federal conviction is unavailable in nearly every circuit.

What is a writ of coram nobis, and where does the power come from?

Coram nobis is Latin — literally “before us,” short for quae coram nobis resident, “which remain before us.” At common law it was a motion asking the same court that entered a judgment to correct an error of fact that never made it into the record. The related writ coram vobis (“before you”) was directed to a different court; in modern federal practice the distinction has collapsed and the two terms are used interchangeably, which is why you will see “writ of error coram nobis,” “coram nobis writ,” and “error coram nobis” describing the same filing.

The modern federal writ traces to United States v. Morgan, 346 U.S. 502 (1954). Morgan had finished a federal sentence and was serving a longer state sentence made harsher by the federal conviction; he claimed he had been tried without counsel. The government argued that the 1948 enactment of § 2255 had displaced any residual power. The Court disagreed: “We do not think that the enactment of § 2255 is a bar to this motion, and we hold that the District Court has power to grant such a motion.” The Court located the power in what it called “the all-writs section of the Judicial Code” — now 28 U.S.C. § 1651(a), which provides that federal courts “may issue all writs necessary or appropriate in aid of their respective jurisdictions and agreeable to the usages and principles of law.”

It is worth saying plainly what coram nobis is not, because searchers ask: it is not habeas corpus. Habeas is a civil proceeding against a custodian, testing the lawfulness of custody; coram nobis is a motion filed back in the criminal case by someone who has no custodian left. For the writ’s history and what it actually orders, see habeas corpus definition.

Two structural points follow, and both matter procedurally. First, § 1651(a) is not itself a grant of jurisdiction. As the Supreme Court put it in United States v. Denedo, 556 U.S. 904 (2009), “a court’s power to issue any form of relief — extraordinary or otherwise — is contingent on that court’s subject-matter jurisdiction over the case or controversy.” Second, and for the same reason, coram nobis is “properly viewed as a belated extension of the original proceeding during which the error allegedly transpired” — quoting Morgan, “a step in the criminal case and not, like habeas corpus where relief is sought in a separate case and record, the beginning of a separate civil proceeding.” That is why the petition goes back to the court of conviction.

One point regularly confuses people who search the rules. Fed. R. Civ. P. 60(e) states flatly: “Bills and Writs Abolished. The following are abolished: bills of review, bills in the nature of bills of review, and writs of coram nobis, coram vobis, and audita querela.” That abolition is confined to civil cases. Morgan held the writ survives on the criminal side, and it has ever since.

Finally, temper expectations with the Supreme Court’s own language. In Carlisle v. United States, 517 U.S. 416, 429 (1996), the Court repeated that “it is difficult to conceive of a situation in a federal criminal case today where [a writ of coram nobis] would be necessary or appropriate.” Federal courts quote that line constantly, and they mean it.

Who coram nobis is for: the custody gap in § 2255

Everything else in this section — grounds, deadlines, hearings, appeals — assumes you satisfy § 2255’s custody requirement. “Custody” is broader than a prison cell: it includes parole, probation, and supervised release. But it is not permanent. When the last day of supervision passes, § 2255 closes as a matter of law, and it closes whether or not you had a meritorious claim and whether or not anyone told you the clock was running.

That is not a technicality; it is the design. The table below is the eligibility map.

Table 1. Custody status, available federal vehicle, and governing authority.

Your status	Available federal vehicle	Governing authority	What it can do
Serving a federal prison term	Motion to vacate under § 2255	28 U.S.C. § 2255(a)	Vacate, set aside, or correct the sentence; order a new trial; resentence
On federal supervised release, probation, or parole	Motion to vacate under § 2255 — coram nobis is unavailable	§ 2255(a); Matus-Leva v. United States, 287 F.3d 758 (9th Cir. 2002)	Same as above
Released on bail or personal recognizance pending appeal	§ 2255 not yet ripe; direct appeal	§ 2255(a)	—
In custody, but the claim attacks how the sentence is being executed rather than its validity	Petition under § 2241, filed in the district of confinement — see 28 U.S.C. § 2241	28 U.S.C. § 2241	Correct computation, credit, or conditions of execution
Sentence and all supervision fully completed	Writ of error coram nobis	28 U.S.C. § 1651(a); United States v. Morgan, 346 U.S. 502 (1954)	Vacate the conviction
Sentence complete, but you already litigated a § 2255	Coram nobis — filed without appellate pre-authorization in the Eighth Circuit, but measured against § 2255(h)’s substantive standard	Baranski v. United States, 880 F.3d 951 (8th Cir. 2018)	Vacate the conviction, on a materially harder showing
Sentence complete, and you want the record erased rather than the conviction vacated	Generally nothing — equitable expungement of a valid federal conviction is unavailable in nearly every circuit	United States v. Batmasian, 66 F.4th 1278 (11th Cir. 2023)	—

The four-element federal coram nobis test (Ninth Circuit formulation, the most frequently quoted):

1. A more usual remedy is not available.
2. Valid reasons exist for not attacking the conviction earlier.
3. Adverse consequences exist from the conviction sufficient to satisfy the case-or-controversy requirement of Article III.
4. The error is of the most fundamental character.

Hirabayashi v. United States, 828 F.2d 591 (9th Cir. 1987); restated in United States v. Riedl, 496 F.3d 1003 (9th Cir. 2007), and again in Cervantes-Torres v. United States, 141 F.4th 1101 (9th Cir. 2025). The requirements are conjunctive — Matus-Leva says so directly: “failure to meet any one of them is fatal.”

Not every circuit counts to four. The Second Circuit states three elements: circumstances compelling such action to achieve justice; sound reasons for failure to seek earlier relief; and continuing legal consequences remediable by the writ. Foont v. United States, 93 F.3d 76 (2d Cir. 1996). The First Circuit likewise uses three — explain the failure to seek earlier relief, show significant continuing collateral consequences, and show an error of the most fundamental character — and adds an overarching discretionary check: even when all three are met, a court may deny the writ if the petitioner “fails to show that justice demands the extraordinary balm of coram nobis relief.” Aceituno v. United States, 132 F.4th 563 (1st Cir. 2025). The content is the same; the count differs. If you are comparing forms you find online, check which circuit’s formulation they use.

If you are still in custody and trying to work out what § 2255 covers, start with what is a 2255 motion; if you are deciding whether to hire counsel for a collateral attack at all, the hub on hiring a federal 2255 motion lawyer covers the engagement itself.

Applied Insight — Elizabeth Franklin-Best, Esq., Principal Attorney: The first document we ask for in a coram nobis case is the judgment, and the second is proof of the exact date supervision terminated. Those two dates decide whether we are drafting a § 2255 or a coram nobis petition, and the answer changes the entire filing — the elements, the standard, and the court’s discretion. People routinely tell us their sentence is “over” when they mean they are out of prison. Those are not the same thing, and filing the wrong one wastes the only shot at the claim.

“Errors of the most fundamental character” — what actually qualifies

Morgan imported the phrase from earlier Supreme Court practice: coram nobis reaches errors “of the most fundamental character,” meaning defects “such as to render the proceeding itself irregular and invalid.” In Morgan the qualifying error was a federal trial conducted without a competent and intelligent waiver of counsel — a structural Sixth Amendment failure.

Denedo confirmed that the modern writ is broader than the common-law original: “[a]ny rationale confining the writ to technical errors . . . has been superseded; for in its modern iteration coram nobis is broader than its common-law predecessor,” and it can redress “a fundamental error, there a deprivation of counsel in violation of the Sixth Amendment, as opposed to mere technical errors.” But Denedo immediately reimposed the limit: “an extraordinary remedy may not issue when alternative remedies, such as habeas corpus, are available.”

Two constraints do most of the practical work.

First, the standard is higher than direct appeal. Because coram nobis is collateral review, a petitioner “must clear a significantly higher hurdle than would exist on direct appeal.” The Ninth Circuit’s 2025 decision in Cervantes-Torres turned that into a usable screen for unpreserved errors: if the error would not survive plain-error review on direct appeal, “it cannot be of the most fundamental sort, either.” A judge reviewing a Rehaif-type instructional omission against overwhelming evidence of knowledge will deny relief on exactly that reasoning.

Second, new evidence alone is not enough. The Second Circuit stated it plainly in Foont: “[c]laims of new evidence, however, without constitutional or jurisdictional error in the underlying proceeding, cannot support a coram nobis claim.” That is the same architecture that governs innocence claims generally — innocence is usually a gateway rather than a standalone claim — and it is why a coram nobis petition needs to be framed around the constitutional defect the new information exposes. The vehicles and standards for innocence proof specifically are mapped on the wrongful conviction attorney page.

Because the underlying error has to be one a court could have corrected collaterally in the first place, the claim inventory is the same one that governs a § 2255 motion. What kinds of claims succeed is covered at grounds for a 2255 motion; what courts refuse to hear no matter how strong the underlying complaint is covered at claims not cognizable 2255. If a claim would have failed under § 2255 on cognizability grounds, it does not become viable simply because the sentence is over.

Continuing collateral consequences: what actually counts

This element is where the writ’s Article III footing lives. A conviction whose consequences are entirely spent presents no live case or controversy, so the petitioner must show that something is still happening to him because of it.

The circuits do not describe the burden identically, and the difference is not academic.

The Ninth Circuit presumes consequences. Hirabayashi adopted the mootness framing from Sibron v. New York: “a criminal case is moot only if it is shown that there is no possibility that any collateral legal consequences will be imposed on the basis of the challenged conviction.” The court rejected the government’s argument that a petitioner must identify a specific legislative disability, reasoning that “most criminal convictions do in fact entail adverse collateral legal consequences” and that the “mere ‘possibility'” of them is enough.

The Fifth Circuit requires a demonstrated civil disability. United States v. Esogbue, 357 F.3d 532 (5th Cir. 2004), describes the writ as available “where the petitioner can demonstrate civil disabilities as a consequence of the conviction.” Esogbue held that a pending deportation qualifies — deportation is a collateral consequence that does not make a person “in custody,” but it is exactly the kind of continuing disability coram nobis addresses.

In practice, the consequences that actually persuade courts fall into four families:

• Immigration — removal proceedings, inadmissibility, a bar on naturalization, or ineligibility for relief from removal. This is the most common and the most successful category.
• Professional licensure — a conviction that triggers exclusion from a licensed profession or from a federal program. A lifetime bar on practicing a licensed profession is a materially stronger showing than a general employment complaint.
• Firearm rights — the federal felon-in-possession disability, and its effect on any subsequent prosecution.
• Employment and housing — the weakest category standing alone. District courts regularly reject generic assertions that a record makes work or housing harder, because those consequences attach to every conviction and prove nothing specific about this one.

The practical drafting lesson: do not plead consequences generically. Plead the specific statute, regulation, licensing rule, or immigration provision that operates on this conviction, and attach the document that shows it operating — the notice to appear, the licensing board’s denial letter, the program exclusion.

Sound reasons for the delay — where most petitions fail

There is no statute of limitations on coram nobis. Morgan traced the common-law writ as one “allowed without limitation of time for facts that affect the ‘validity and regularity’ of the judgment.” But Morgan also conditioned relief on “sound reasons existing for failure to seek appropriate earlier relief,” and that condition is where most modern petitions die.

Courts assess it individually. Foont held that “an error of constitutional dimension at the time of plea or sentence renders a conviction voidable, not void, and coram nobis relief may be barred by the passage of time,” and that “[a] district court considering the timeliness of a petition for a writ of error coram nobis must decide the issue in light of the circumstances of the individual case.”

The circuits disagree about what the inquiry measures. The Second Circuit reads Morgan’s “sound reasons” requirement as directed at the petitioner: it declines to “read Morgan as incorporating a laches concept,” interpreting the requirement as “calling to the attention of the district court the circumstances surrounding the petitioner’s failure to raise the issue earlier rather than the government’s injury that resulted from the delay.” Foont. The Ninth Circuit reaches a different arrangement: laches “does not supplant or restate” the petitioner’s obligation to show valid reasons, “but rather constitutes a supplemental defense that the government may invoke.” Riedl. The upshot in the Ninth Circuit is that the government’s inability to show prejudice does not excuse an unexplained delay — a point Riedl made while affirming denial of a six-year-old petition.

Three recurring delay arguments fail:

1. “I could have raised it earlier but did not.” Riedl treated exactly that concession as “fatal,” quoting the Seventh Circuit’s rule that “[c]laims that could have been raised by direct appeal are outside the scope of the writ.”
2. “I was pursuing immigration relief first.” The First Circuit rejected this in Aceituno, holding that the petitioner “could have pursued both avenues for relief . . . at the same time,” and pointing to the Third Circuit’s decision in Ragbir v. United States, 950 F.3d 54 (3d Cir. 2020), which Aceituno describes as declining to excuse a six-year delay where the petitioner “offer[ed] no acceptable explanation for why he did not seek both forms of relief concurrently.” Aceituno also confirms that “[t]he consideration of delay by a coram nobis petitioner inherently includes consideration of whether the petitioner has exercised diligence.”
3. “§ 2255 was time-barred, so coram nobis is my only option.” Matus-Leva: “[a] petitioner may not resort to coram nobis merely because he has failed to meet the AEDPA’s gatekeeping requirements.” If you are still in custody, missing the § 2255 deadline does not convert your case into a coram nobis case. Whether anything saves a late § 2255 is a separate question, covered at equitable tolling.

What does work is a documented account of when the consequence first became concrete — the day removal proceedings started, the day the licensing board acted, the day an intervening decision changed the law — paired with what you did next and how quickly. If you are trying to work out which clocks were running against you at each stage, and which one is running now, the full inventory is at federal appeal deadline.

Applied Insight — Christopher Zoukis, JD, MBA, Managing Director: In consulting work the delay question almost always comes down to records nobody thought to keep. A client learns his green-card renewal was denied because of a fifteen-year-old federal conviction, and by the time a lawyer sees the file the notice is gone. Keep every letter, every denial, every licensing communication, and note the date you received it. When the petition eventually explains the delay, that paper is the difference between a timeline a judge can verify and a narrative he cannot.

Immigration consequences and the Padilla wall

Coram nobis and immigration law intersect constantly, because deportation is the paradigm continuing consequence and because the people it affects are usually long out of custody.

The doctrinal hook is Padilla v. Kentucky, 559 U.S. 356 (2010), which held that the Sixth Amendment requires defense counsel to advise a noncitizen client about the deportation risk of a guilty plea. The Court calibrated the duty: “[w]hen the law is not succinct and straightforward . . . a criminal defense attorney need do no more than advise a noncitizen client that pending criminal charges may carry a risk of adverse immigration consequences. But when the deportation consequence is truly clear, as it was in this case, the duty to give correct advice is equally clear.” The Court also held that the direct-versus-collateral-consequence distinction is “ill suited to evaluating a Strickland claim concerning the specific risk of deportation,” and that prejudice requires convincing the court “that a decision to reject the plea bargain would have been rational under the circumstances.” The two-prong framework itself is covered on our Strickland v. Washington page, and the plea-stage application at guilty plea ineffective assistance.

Then comes the wall. Chaidez v. United States, 568 U.S. 342 (2013), held that Padilla announced a new rule and therefore “does not have retroactive effect” for anyone whose conviction became final before Padilla was decided. Chaidez itself was a coram nobis case — its footnote explains that “[a] petition for a writ of coram nobis provides a way to collaterally attack a criminal conviction for a person, like Chaidez, who is no longer ‘in custody’ and therefore cannot seek collateral relief under 28 U.S.C. § 2255 or habeas relief under § 2241,” citing Morgan. District courts apply Chaidez routinely and mechanically. If your conviction became final before March 31, 2010, a pure Padilla claim will not get you relief, and recasting it as “not a strict Padilla claim” is a move courts have seen and rejected. Whether an intervening decision applies to an already-final conviction is the general question covered on our page on retroactive Supreme Court decisions.

Two further limits are worth knowing before you spend money. First, Aceituno holds that Padilla’s duty runs to the risk of deportation, not to every adverse immigration consequence — counsel was not constitutionally required to warn about a permanent reentry bar. Second, courts deny relief where vacating the conviction would not actually remove the consequence: if a person’s presence is independently unlawful, or removability rests on other grounds, the writ would not “remedy any legal consequences from his conviction,” and the third element fails.

Affirmative misadvice claims that predate Padilla are a different matter in some circuits, and immigration-consequence advice given after March 2010 is squarely governed by Padilla itself. That is a fact-specific inquiry, and it is the first thing to have evaluated. The broader question of which attorney failures courts have actually accepted as constitutionally deficient — and what proof each requires — is covered at ineffective assistance of counsel.

Does supervised release count as custody?

Yes, and this single point disposes of a large share of the coram nobis petitions filed each year.

The Supreme Court held in Jones v. Cunningham, 371 U.S. 236 (1963), that a parolee is “in custody” for habeas purposes because the conditions of release “significantly restrain petitioner’s liberty.” Federal supervised release imposes the same kind of restraints — reporting, travel restrictions, association conditions, search conditions, and exposure to revocation and reimprisonment — and the courts of appeals apply the same rule to it. Whether you are still in custody in the first place — on supervised release, under a detainer, or serving consecutive sentences — is the threshold question worked through on our page on the § 2255 custody requirement.

The Ninth Circuit’s decision in Matus-Leva v. United States, 287 F.3d 758 (9th Cir. 2002), is the cleanest statement of the consequence: “Matus-Leva cannot overcome the first hurdle because he is still subject to supervised release, and thus he is in ‘custody.’ . . . Because the more usual remedy of a habeas petition is available, the writ of error coram nobis is not.”

Two practical consequences follow. First, if you are on supervision, file under § 2255 — and file within the one-year window, which is computed on the 2255 statute of limitations page. Second, a coram nobis petition filed while you are still on supervision is not merely premature; it will be denied on element one, and by the time supervision ends the delay clock has been running against you the whole time. If your supervision is ending soon and you have a claim, that is the moment to get it evaluated — not after.

Where and how you file

Court. The petition goes to the court that entered the judgment of conviction. That follows from Morgan and from Denedo’s framing of coram nobis as “a belated extension of the original proceeding” and “a step in the criminal case.” It is filed under the original criminal docket number, though clerks in some districts also open a miscellaneous civil number.

Caption and content. The filing is styled a petition (or motion) for a writ of error coram nobis under 28 U.S.C. § 1651(a). There is no official AO form for it — unlike the AO 243 form used for § 2255 motions, whose mechanics are covered at how to file a 2255 motion — so the pleading is drafted from scratch. It has to affirmatively plead all four elements, because a court will not infer them. In practice that means: (a) the exact date supervision terminated, with documentation; (b) the specific continuing consequence, with the document showing it; (c) a dated chronology explaining the delay; and (d) the fundamental error, with record citations.

Evidence. Because there is no analogue to the Rules Governing Section 2255 Proceedings, there is no built-in discovery mechanism and no rule requiring appointment of counsel if a hearing is warranted. The petition has to be self-proving on the papers — sworn declarations, the underlying record, and documentary proof of the consequence.

Appeal. This is the one place the rules are explicit. Fed. R. App. P. 4(a)(1)(C) provides that “[a]n appeal from an order granting or denying an application for a writ of error coram nobis is an appeal in a civil case for purposes of Rule 4(a).” Because the United States is a party, Rule 4(a)(1)(B) gives 60 days after entry of the order to file the notice of appeal — not the 14 days that governs a criminal appeal. Getting that wrong is fatal and avoidable.

Standard of review on appeal. The Ninth Circuit reviews the denial of a coram nobis petition de novo. Riedl. The Second Circuit reviews the ultimate “sound reasons” determination for abuse of discretion. Foont. That difference is worth knowing before you decide whether to appeal. It is also a different posture from a denied § 2255, where an appeal cannot proceed at all without a certificate of appealability under 28 U.S.C. § 2253(c).

Is there a right to appointed counsel?

No. There is no constitutional right to counsel in collateral proceedings at all. Pennsylvania v. Finley, 481 U.S. 551 (1987): “We have never held that prisoners have a constitutional right to counsel when mounting collateral attacks upon their convictions . . . . Our cases establish that the right to appointed counsel extends to the first appeal of right, and no further.”

Nor is there the statutory hook that exists elsewhere in this area. 18 U.S.C. § 3006A(a)(2)(B) authorizes appointed representation, “[w]henever the United States magistrate judge or the court determines that the interests of justice so require,” for a financially eligible person “seeking relief under section 2241, 2254, or 2255 of title 28.” Coram nobis is not on that list. Separately, Rule 8(c), Rules Governing Section 2255 Proceedings, makes appointment mandatory for a qualifying movant once a § 2255 evidentiary hearing is warranted — “the judge must appoint an attorney.” No parallel rule governs coram nobis.

The practical consequence is that coram nobis petitioners are overwhelmingly pro se or privately retained, and that the quality of the initial filing matters more than in almost any other post-conviction posture. There is no court-appointed lawyer coming to fix a defective petition, no rule guaranteeing the kind of hearing described at 2255 evidentiary hearing, and no second bite once a court has ruled on the merits. If you are weighing whether to retain counsel, the honest comparison point is what collateral relief actually achieves overall; see 2255 motion success rate for the data on the § 2255 side of the house.

Coram nobis compared with a pardon and with expungement

These three are constantly confused, and they do different things.

Coram nobis vacates the conviction. A granted writ sets aside the judgment. The legal disabilities that flowed from it — immigration consequences, licensure bars, the firearm disability — fall away with it, because the conviction no longer exists. The government may in principle re-prosecute, though after a completed sentence and years of delay that is rare.

A pardon forgives the punishment; it does not erase the conviction. The pardon power comes from Article II, § 2, cl. 1 of the Constitution and is exercised by the President; federal clemency petitions are processed through the Department of Justice’s Office of the Pardon Attorney. But the Department’s own Office of Legal Counsel has concluded that “[a] presidential pardon granted under Article II, Section 2 of the Constitution does not automatically expunge Judicial or Executive Branch records relating to the conviction or underlying offense,” and that a pardon “does not erase the conviction as a historical fact or justify the fiction that the pardoned individual did not engage in criminal conduct.” Whether a Presidential Pardon Expunges Judicial and Executive Branch Records of a Crime, Op. O.L.C. (Aug. 11, 2006). A pardon is also discretionary, slow, and not a judicial remedy at all.

Expungement of a valid federal conviction is, in nearly every circuit, unavailable. There is no general federal expungement statute for adult convictions. And after Kokkonen v. Guardian Life Insurance Co. of America, 511 U.S. 375 (1994) — which confined ancillary jurisdiction to two purposes, permitting a single court to dispose of factually interdependent claims and enabling a court “to manage its proceedings, vindicate its authority, and effectuate its decrees” — the courts of appeals have overwhelmingly held that a district court lacks ancillary jurisdiction to expunge a valid record on equitable grounds. The Eleventh Circuit collected the consensus in United States v. Batmasian, 66 F.4th 1278 (11th Cir. 2023), noting that “the First, Second, Third, Sixth, Seventh, Eighth, and Ninth Circuits have declined to recognize that they have ancillary jurisdiction to hear equitable expungement motions in light of Kokkonen,” and holding that “no court has ever recognized ancillary jurisdiction over a constitutional expungement where the alleged constitutional violation was the natural result of an otherwise valid arrest or conviction.” The narrow exception the Sixth Circuit has described — and the Eleventh Circuit agreed with — is that ancillary jurisdiction may exist where the motion challenges the arrest or conviction as unconstitutional. That is not equitable expungement; that is coram nobis by another name.

So the sequence for someone whose completed federal conviction is costing them something is: coram nobis if there is a fundamental error to attack; clemency if there is not; and expungement essentially never. Where coram nobis sits within the wider menu of remedies — and what each one can actually change about a conviction or sentence — is mapped at post conviction relief, and the question of who handles these matters after the direct appeal is finished is answered at post conviction attorney.

Coram nobis after an earlier § 2255

If you filed a § 2255 while you were in custody and lost, the coram nobis petition you file after release is not a clean slate.

The Eighth Circuit addressed this squarely in Baranski v. United States, 880 F.3d 951 (8th Cir. 2018). On the procedural question, it held that a coram nobis petitioner does not need three-judge-panel authorization, because § 2244(b) is “plainly limited to ‘a second or successive habeas corpus application'” and § 2255(h)’s cross-reference is limited to a “second or successive [§ 2255] motion” — and “[a]s Congress did not impose this restriction on coram nobis petitioners seeking successive post-conviction relief, we may not read it into the statutes.”

On the substance, the court went the other way. It applied § 2255(h)(1)’s standard directly, reasoning that a petitioner no longer in custody should not obtain relief “with a less rigorous substantive showing” than a prisoner would face, and reiterating the circuit’s rule that “[t]he writ of coram nobis may not be used to circumvent the clear congressional directive embodied in the ‘second or successive’ provisions of § 2255.” That directive is a 1996 addition — what AEDPA changed and which restrictions it imposes is covered on our AEDPA page. That means newly discovered evidence “sufficient to establish by clear and convincing evidence that no reasonable factfinder would have found the movant guilty of the offense” — a demanding bar that impeachment material will not clear.

Treat this as Eighth Circuit law rather than a national rule; the circuits have not adopted a uniform approach, and four judges of that court would have reheard the case en banc.

One recent decision is being misread on the § 2255(h) side of this, so be precise about it. Bowe v. United States, 607 U.S. 13 (2026), decided January 9, 2026, held that § 2244(b)(3)(E)’s certiorari bar does not apply to federal prisoners and that § 2244(b)(1)’s old-claim bar reaches only state prisoners under § 2254. It did not loosen § 2255(h) or remove the second-or-successive restrictions — it reaffirmed Jones v. Hendrix’s description of § 2255(h) as the “two—and only two—conditions in which a second or successive §2255 motion may proceed,” and read § 2255(h)’s cross-reference as incorporating § 2244’s procedures “only as they relate to how a panel certifies a second or successive filing.” A Seventh Circuit judge confirmed the narrow reading, in chambers, in Upchurch v. United States, No. 26-1114 (7th Cir. Aug. 4, 2026). Because Baranski imports § 2255(h)’s substantive standard into coram nobis, nothing in Bowe eases the showing a successive coram nobis petitioner must make. For the mechanics of the § 2255(h) gate itself, see second or successive 2255.

Applied Insight — Elizabeth Franklin-Best, Esq., Principal Attorney: We build coram nobis petitions backward from the consequence. Before we look at the trial record, we want to see the document that is hurting the client today — the notice to appear, the board’s denial, the exclusion letter. That document does three things at once: it establishes the third element, it dates the delay clock, and it tells us what the client actually needs, which is sometimes not vacatur at all. A petition that leads with a compelling legal error and treats the consequence as an afterthought is a petition that gets denied on standing.
