Docket 24-1063October Term 2025 (2025–2026)

What it's about

The Court considered whether a defendant who agreed not to appeal his sentence as part of a plea deal could still challenge a supervised-release condition requiring him to take prescribed mental-health medication. The Court held that appeal waivers are not absolute and may be refused when enforcing them would create a miscarriage of justice, then sent Hunter’s case back for that standard to be applied.

Question presented

1. Does an appeal waiver bar all claims except for ineffective assistance of counsel or a sentence exceeding the statutory maximum? 2. Does such a waiver become ineffective if the sentencing judge later tells the defendant they can appeal, and the government fails to object?

Briefing

What it's about

The case asked whether a defendant who waived most appeal rights in a plea deal could still challenge a supervised-release condition requiring prescribed mental-health medication. The Supreme Court said appeal waivers are not absolute and can be refused when enforcing them would create a miscarriage of justice, then sent Hunter's case back for that test to be applied.

Vote

The Court ruled for Hunter on the legal standard and returned the case to the lower courts, but the prompt does not provide the vote count or opinion lineup.

Impact

This gives lower courts room to hear some appeals even after a plea agreement waiver, especially when a sentence condition seems unusually unfair. For example, a defendant challenging a serious supervised-release rule may still get review if enforcing the waiver would be unjust.

What's next

The Fifth Circuit must reconsider Hunter's appeal using the miscarriage-of-justice standard the Supreme Court announced. Lower courts will also have to decide, case by case, when enforcing an appeal waiver would be too unfair.

What was the main fight in Hunter v. United States?

The dispute was whether Hunter's plea-deal waiver blocked his challenge to a supervised-release condition requiring prescribed mental-health medication. The Court said such waivers are not absolute.

Who is most affected by this ruling in real life?

Defendants who signed plea deals with appeal waivers may benefit when a sentence condition appears especially unfair. Judges and prosecutors must also account for this new limit.

What happens next in Hunter's own case?

The Supreme Court sent the case back to the Fifth Circuit. That court must decide whether enforcing Hunter's waiver here would create a miscarriage of justice.

Decision

Decision record

What the Court decided

Appeal waivers usually matter, but they do not automatically block every appeal when enforcing them would cause a miscarriage of justice.

Impact

Federal defendants who signed an appeal waiver (a promise not to challenge a future sentence) are affected. Their waiver is not absolute. For example, Hunter may still challenge a supervised-release medication requirement if enforcing the waiver would cause a miscarriage of justice. Next, lower courts must decide whether a claimed sentencing error is obvious and extreme enough. Hunter's case returns to the Fifth Circuit to apply that standard.
