Old Chief v. United States
The Supreme Court ruled that when a defendant charged with illegal gun possession offers to stipulate that he has a prior felony conviction, a trial judge abuses its discretion by instead letting prosecutors introduce the full record naming and describing that earlier crime.
The decision limits prosecutors' usual freedom to present evidence however they choose, holding that when the only point of evidence is proving a defendant's legal status as a felon, an admission carries the same proof value as the record but without the risk that jurors will convict based on the defendant's past bad acts rather than the charge at hand.
“There is, accordingly, no question that propensity would be an "improper basis" for conviction and that evidence of a prior conviction is subject to analysis under Rule 403 for relative probative value and for prejudicial risk of misuse as propensity evidence.”
Explaining why evidence of a prior crime risks improper propensity reasoning by jurors.
How it got here: The trial court let prosecutors introduce the full prior-conviction record over Old Chief's objection; the Ninth Circuit affirmed; the Supreme Court took the case to resolve a circuit split.
The Case in Depth
What happened
Johnny Lynn Old Chief was charged with being a felon in possession of a firearm after an incident involving a gunshot. His prior conviction was for assault causing serious bodily injury. Worried that jurors would use the name of that violent prior crime to assume he was guilty of the current gun and assault charges, he offered to stipulate that he had a qualifying felony conviction rather than let the jury hear the details.
The question before the Court
If a felon on trial for illegally owning a gun offers to admit he has a qualifying prior conviction, can prosecutors still show the jury the record naming his earlier crime?
The Court's answer
No — once Old Chief offered to stipulate that he had a qualifying prior felony conviction, the trial court abused its discretion by instead letting the government introduce the full record naming his earlier crime (assault causing serious bodily injury). Under the rule governing unfair prejudice, evidence should be excluded when its risk of an improper verdict substantially outweighs its added value, and here the stipulation would have proven the same legal fact just as conclusively.
The Court explained that proving a defendant's status as a past felon is different from proving what he did in the current case: it doesn't require a "continuous story" the way ordinary evidence of a crime does, so the usual rule letting prosecutors pick their own proof doesn't carry the same force here. Because the name and nature of the earlier crime added no legitimate proof beyond what a stipulation would show, while risking that jurors would convict based on his past instead of the present charge, the trial court should have accepted the stipulation.

Why it matters
Defendants charged with illegal firearm possession by felons can now generally keep the name and details of their prior crime away from the jury by offering to stipulate to felon status, reducing the risk that jurors convict based on assumptions about bad character rather than the gun charge itself. Prosecutors retain full freedom to prove other elements however they choose.
What changes now
The case is sent back to the Ninth Circuit for further proceedings applying the new rule, including consideration of whether the error was harmless. This is a final merits decision that establishes a general rule for felon-in-possession prosecutions: when a defendant offers to stipulate to prior-conviction status alone, courts should generally accept the stipulation rather than admit the full record naming the earlier crime.
What this does not decide
The Court expressly limited its holding to cases where the prior conviction is used solely to prove the defendant's legal status as a felon, not to cases where evidence of a prior crime is offered for some other purpose like motive or intent, or where a defendant seeks to stipulate away elements requiring a fuller narrative of the current offense.
Concurrences and dissents
Dissent — Justice O'Connor
“Moreover, crimes have names; a defendant is not convicted of some indeterminate, unspecified "crime."”O'Connor's core objection that naming the prior offense is ordinary, direct proof rather than unfair prejudice.
Justice O'Connor argued that revealing the name and nature of a prior conviction is not 'unfair' prejudice, because Congress itself defined the felon-in-possession offense by reference to specific types of prior crimes, so proving which crime occurred is direct proof of an element, not improper character evidence. She also argued the majority's rule improperly lets a defendant force the government to accept a partial guilty plea and stipulate away its constitutional burden of proving every element to the jury, and that any residual risk could be handled with limiting instructions instead.
How the Court got there
The legal reasoning, step by step
- The Court first confirmed that evidence naming the prior offense was technically relevant under the ordinary relevance rule, since it made Old Chief's status as a qualifying felon more probable — but relevance alone doesn't guarantee admissibility.
- The central question was how to apply Rule 403, the rule letting judges exclude relevant evidence when its risk of an unfair, improper verdict substantially outweighs its added value. The Court held that in weighing 'probative value,' a judge may compare the evidence offered against other available proof of the same fact, discounting the value of one piece when a less risky alternative would prove the same point just as well.
- Naming a defendant's earlier crime carries a real risk of 'propensity reasoning' — jurors treating a past bad act as proof the defendant is the type of person who commits crimes, and convicting on that basis rather than proof specific to the current charge. That risk is especially high when the earlier crime resembles the current charges, as it did here.
- The Court distinguished proof of a defendant's legal status (such as being a past felon) from ordinary proof of what a defendant did in the crime charged. Because status proof doesn't need to tell a continuous story of the current offense, the traditional rule letting prosecutors present their case 'their own way' carries far less force for this narrow element.
- Since Old Chief's offer to stipulate would have established the prior-conviction element just as conclusively as the government's record, while avoiding the risk of an improper verdict based on the name and nature of his earlier crime, the discounted probative value of the government's evidence was substantially outweighed by its unfair prejudicial risk.
- The Court therefore concluded that admitting the full record instead of accepting the stipulation was an abuse of discretion, limiting this rule specifically to cases where the sole purpose of the evidence is proving felon status.
