Daniels v. United States
The Supreme Court ruled that a federal prisoner generally cannot use a post-conviction motion under 28 U.S.C. § 2255 to challenge old state convictions that were used to lengthen his federal sentence, extending a rule the Court had already applied at sentencing itself.
The decision leaves only a narrow, undefined exception for rare cases where a defendant truly had no earlier chance to challenge the prior conviction, meaning most people sentenced under repeat-offender laws like the Armed Career Criminal Act cannot revisit decades-old convictions once the door to direct or state collateral review has closed.
“The presumption of validity that attached to the prior conviction at the time of sentencing is conclusive, and the defendant may not collaterally attack his prior conviction through a motion under § 2255.”
The Court's core holding barring most challenges to prior convictions in §2255 motions.
How it got here: A federal district court denied Daniels's motion to correct his sentence; the Ninth Circuit affirmed; the Supreme Court took the case because appeals courts disagreed on the rule.
The Case in Depth
What happened
Earthy Daniels was convicted of illegally possessing a firearm, and the government sought a mandatory 15-year sentence under the Armed Career Criminal Act because of four prior convictions, including 1978 and 1981 robbery convictions. After his sentence became final, Daniels filed a motion claiming those two robbery convictions were unconstitutional because his guilty pleas were not knowing and voluntary and because his lawyer had been ineffective.
The question before the Court
If a federal prisoner's sentence was lengthened because of old state convictions, can he later attack those old convictions as unconstitutional in a federal motion challenging his current sentence?
The Court's answer
No — with only a narrow, mostly theoretical exception. The Court held that once a prior conviction is no longer open to challenge through direct appeal or state collateral review, it becomes conclusively valid for use in enhancing a later federal sentence, and a federal prisoner generally cannot attack it through a §2255 motion. The only firm exception, carried over from an earlier case, is for convictions obtained without a lawyer at all.
The Court reasoned that district courts reviewing §2255 motions face the same practical problems sentencing courts do — old records are hard to find — and that states retain a real interest in the finality of their judgments even years later. The Court left open, but did not decide, whether relief might be available in the rare case where a defendant truly never had any chance to challenge the conviction earlier through no fault of his own.

Why it matters
People convicted under federal repeat-offender laws like the Armed Career Criminal Act often face many extra years in prison because of decades-old state convictions. This ruling means most of them cannot reopen those old cases through federal habeas motions once ordinary channels to challenge them have lapsed, even if they believe those convictions were unconstitutional.
What changes now
The ruling is final on the merits and resolves the specific split among appeals courts over whether Custis's sentencing-hearing rule also applies to later §2255 motions. Daniels's sentence stands as enhanced. The Court left open, without resolving, whether §2255 relief might ever be available in a truly rare case where no review channel was ever open to a defendant, so that narrow question remains for future litigation.
What this does not decide
The Court did not decide whether §2255 relief is ever available in the rare situation where a defendant genuinely had no opportunity, through no fault of his own, to challenge a prior conviction before it was used to enhance his sentence. It also did not resolve what happens if a defendant later succeeds in overturning the prior conviction elsewhere.
Concurrences and dissents
Concurrence in part — Justice Scalia
Justice Scalia agreed with the Court's bottom line and most of its reasoning but refused to join the part suggesting rare exceptions might allow § 2255 relief. He argued the text of § 2255 simply does not cover claims that a sentence is unconstitutional because of a prior conviction, since Custis already established that using such convictions does not itself violate due process, so no textual hook for relief exists at all.
Dissent — Justice Souter
“Why should it be easy to subject a person to a higher sentencing range and commit him for nearly nine extra years (as here) when the prisoner has a colorable claim that the extended commitment rests on a conviction the Constitution would condemn?”Souter's objection that finality concerns should not outweigh a genuine constitutional claim.
Justice Souter argued Custis only decided where a defendant could challenge a prior conviction, not whether he could at all, and that here the door to other review had already closed, making the stakes different. He contended the broad text of § 2255 covers such claims, and that barring relief when no other forum exists creates an unfair, one-way finality rule with no textual or precedential support.
Dissent — Justice Breyer
Justice Breyer argued Congress intended courts to allow challenges to prior convictions at the original sentencing hearing itself, a simpler approach that Custis wrongly foreclosed. Facing the resulting mess of case-by-case exceptions in later habeas proceedings, he concluded the Court should instead reconsider and overturn Custis rather than build an increasingly complicated set of rules on top of it.
How the Court got there
The legal reasoning, step by step
- The Court began from its earlier ruling in Custis v. United States, which held that a defendant generally cannot challenge the constitutionality of prior convictions during the sentencing hearing itself, with only one exception for convictions obtained without a lawyer at all.
- The Court asked whether those same concerns — the difficulty of digging up old state court records and the interest in letting final judgments stay final — applied with equal force once the sentencing was over and the defendant instead brought a post-conviction motion under § 2255.
- The Court concluded the concerns applied just as strongly: a court reviewing a § 2255 motion is no better equipped than a sentencing court to locate decades-old transcripts, and a state retains a real interest in the finality of convictions even after a sentence is fully served, since states attach lasting consequences to convictions.
- Applying a presumption-of-regularity principle, the Court held that once a prior conviction is no longer open to direct or state collateral attack — whether because the defendant let his opportunities lapse or lost on the merits — that conviction becomes conclusively valid for use in a later federal sentence.
- The Court limited this rule's one exception to convictions obtained in violation of the right to counsel, and left open, without deciding, whether § 2255 might be available in the rare case where no channel of review was ever actually open to a defendant through no fault of his own.
- Applying this framework, the Court found Daniels had every opportunity to challenge his 1978 and 1981 convictions while serving those sentences and never did, so his claims could not be reopened through his current federal sentence.
