Davis v. United States
The Supreme Court threw out a unique Fifth Circuit rule that barred defendants from getting even a basic error-check on sentencing arguments they failed to raise at trial, if those arguments involved factual questions.
Every other federal appeals court applies a standard 'plain error' safety valve to all unpreserved arguments, and the Court said the Fifth Circuit's refusal to do the same had no basis in law.
“The text of Rule 52(b) does not immunize factual errors from plain-error review. Our cases likewise do not purport to shield any category of errors from plain-error review.”
The Court's core rationale for rejecting the Fifth Circuit's rule that factual arguments can never receive plain-error review.
How it got here: Davis pleaded guilty in federal district court; the Fifth Circuit refused to review his unpreserved sentencing argument; the Supreme Court granted certiorari and vacated.
The Case in Depth
What happened
Charles Davis was stopped by Dallas police in 2016, who found a handgun and methamphetamine in his car. Because he had prior state felony convictions, he pleaded guilty in federal court to being a felon in possession of a firearm and to drug charges. At sentencing, the judge ordered his federal prison time to run back-to-back with any future sentences from pending state charges — and Davis did not object. Only later, on appeal, did he argue that the federal and state offenses were part of the same conduct and that the sentences should have run at the same time.
The question before the Court
Can a federal appeals court refuse to review any argument a defendant failed to raise at sentencing, simply because the argument involves facts rather than law?
The Court's answer
No — a federal appeals court cannot categorically refuse to look at an unpreserved argument just because it involves factual questions rather than purely legal ones. Federal Rule of Criminal Procedure 52(b), which allows appeals courts to review "plain errors" even when a defendant failed to raise them below, draws no distinction between factual and legal errors. The text of the rule covers both.
The Court added that its own prior cases on plain-error review likewise carve out no category of errors from this safety-valve check. Because the Fifth Circuit's practice of shutting the door on all unpreserved factual arguments had no support in the rule's text or in Supreme Court precedent, that practice cannot stand.

Why it matters
Criminal defendants sentenced in federal court in Texas, Louisiana, and Mississippi — the Fifth Circuit's territory — will now have the same fallback review available to defendants everywhere else in the country. If they miss an argument at sentencing, an appeals court must at least check whether the error was so obvious and harmful it warrants correction, rather than refusing to look at it at all.
What changes now
The case goes back to the Fifth Circuit, which must now apply the standard plain-error test to Davis's argument that his federal sentence should have run at the same time as any state sentences, rather than back-to-back. The Court expressly left open whether Davis will actually win under that test — he still has to show the error was plain, affected his substantial rights, and seriously undermined the fairness of the proceedings.
What this does not decide
The Court did not decide whether Davis's original argument — that his sentences should have run concurrently — is correct or whether he can satisfy the plain-error standard on remand. The ruling only requires the Fifth Circuit to apply plain-error review; it does not guarantee Davis any relief.
How the Court got there
The legal reasoning, step by step
- Federal Rule of Criminal Procedure 52(b) — the plain-error rule — lets an appeals court correct an error even when the defendant never raised it at trial, as long as the error is obvious, affects substantial rights, and would seriously undermine the fairness or integrity of the proceedings. This is the standard safety valve for arguments missed at the trial or sentencing level.
- The Fifth Circuit had carved out an exception: if a defendant's unpreserved argument turned on factual questions (rather than pure legal questions), the appeals court would not apply plain-error review at all — it would simply refuse to consider the argument. Nearly every other federal appeals court applied plain-error review to both factual and legal arguments without distinction.
- The Court read Rule 52(b) as written. The rule says '[a] plain error that affects substantial rights may be considered even though it was not brought to the court's attention' — with no language exempting factual errors from this protection.
- The Court also surveyed its own precedents on plain-error review, including United States v. Olano (1993), the foundational case laying out the plain-error test, and found that none of them purport to shield any category of errors — factual or otherwise — from review under Rule 52(b).
- With neither the rule's text nor Supreme Court case law supporting the Fifth Circuit's categorical exemption, the Court concluded the Fifth Circuit's practice had no legal basis and vacated its judgment, sending the case back for proper plain-error review.
