A citizen's guide to the whole case

What this case is about

The case is Hunter v. United States, No. 24-1063. Justice Gorsuch clarified that only waivers of sentencing errors are before the Court. Hunter's lawyer confirmed that point. The disputed sentence component is a supervised-release medication condition.

How the case got here

The case reached the Supreme Court after earlier proceedings below. The transcript does not describe those lower-court decisions in detail. Lisa S. Blatt argued for Hunter. Zoe A. Jacoby, an Assistant to the Solicitor General, argued for the United States.

What each side wants

Hunter asks the Court at least to remand on a second legal question about warnings. His broader position is that appeal waivers should face ordinary contract defenses. He says plea agreements are contracts, so contract doctrines can excuse appeal waivers.

Hunter proposes a two-gate test. First, the error must be clear and indisputable. Second, it must be egregious—plainly unauthorized by statute or violating constitutional rights. Examples include sentences based on race, religion, or bodily integrity. He cites Rumery for the idea that enforcing contracts is a primary public policy consideration.

What each side says

The United States asks the Court to hold there is no exception allowing Hunter's appeal, rather than remanding. It says knowing and voluntary appeal waivers are enforceable and contract law provides no sentence-based exception.

The government says contract defenses apply in principle but fail here. It argues an open-ended egregious-sentences exception would spur litigation and undermine the benefit of the bargain. It opposes remand, warning of signaling effects and floodgates of litigation. It urges narrow exceptions: race-based sentences, categorically unlawful sentences, and procedures no civilized system would use.

What the justices asked

Chief Justice Roberts asked whether specific warnings must be given about appeal waivers and what their elements would be. Hunter's lawyer answered that the judge need only advise the defendant he may have a right to appeal and should consult the plea agreement.

Justice Thomas asked why statutory rights cannot be waived contractually. He also asked whether the government could void the plea agreement and proceed with dismissed counts. Justice Alito questioned applying the entire law of contracts to plea agreements. Hunter's lawyer answered that appeal rights can be waived, but plea agreements remain contracts governed by contract principles.

Why it matters

Millions of criminal cases end in plea deals rather than trials. If waivers always stick, defendants cannot challenge even badly wrong sentences. If contract defenses apply, some waivers can be excused. The government's narrow proposed exceptions show it sees some limits. Hunter's two-gate test would open a broader path.

What the Court decided

An agreement giving up the right to appeal a sentence cannot be enforced if enforcing it would cause a miscarriage of justice. That means the sentence must contain an egregious, obvious error that would bring the judicial system into disrepute.

The Supreme Court vacated the Fifth Circuit's judgment and remanded the case for it to decide whether Hunter's appeal waiver can be enforced under this standard.
