Opinion Summary: Hunter v. United States | Judicial Review for Pleas that Cause Egregious Errors

Hunter v. United States | Case No. 24-1063 | Docket Link: Here | Argued: 03/03/2026 | Decided: 06/18/2026Overview: A plea deal's appeal waiver collides with a forced-medication sentence, pushing the Supreme Court to decide when courts can void a waiver — reshaping appellate rights for the ninety-five percent of federal defendants who plead guilty.Question Presented: Whether an appeal waiver remains enforceable when enforcing it would create a miscarriage of justice in sentencing.Posture: Fifth Circuit dismissed Hunter's appeal under the waiver; Court granted certiorari to resolve a split.Main Arguments:Petitioner (Hunter): (1) Contract defenses like frustration of purpose render the waiver unenforceable for egregious sentencing errors; (2) the judge's on-record statement granting appeal rights, paired with the prosecutor's silence, voids the waiver; (3) courts must recognize a miscarriage-of-justice exception to prevent egregious, unconstitutional sentencing conditions from escaping all appellate review.Respondent (United States): (1) A knowing and voluntary appeal waiver binds the defendant according to its plain terms; (2) only two narrow exceptions ever excuse a waiver — ineffective assistance and an above-maximum sentence; (3) a broad miscarriage-of-justice exception floods appellate courts and undercuts the value of plea bargaining nationwide.Holding: An agreement not to appeal a sentence is unenforceable when it would result in a miscarriage of justice — meaning, when it would leave in place the kind of egregious error that would bring the judicial system into disrepute.Voting Breakdown: 8-1. Justice Kagan wrote the majority opinion joined by Chief Justice Roberts and Justices Alito, Sotomayor, Gorsuch, Kavanaugh, Barrett, and Jackson. Justice Gorsuch filed a concurring opinion joined by Justices Sotomayor and Jackson. Justice Kavanaugh filed a concurring opinion joined by Justices Alito and Barrett. Justice Barrett filed a concurring opinion. Justice Thomas filed a dissenting opinion. Vacated and remanded.Opinion: HereMajority Reasoning: (1) Hunter's claim that the judge's statement and prosecutor's silence voided the waiver fails, since the agreement requires written, signed modifications and the government's chance to enforce the waiver arises only after a notice of appeal; (2) courts retain independent authority over plea waivers, since judges must approve every agreement and appellate courts control enforcement; (3) a miscarriage-of-justice standard, requiring an obvious and egregious error, replaces both the government's absolute-enforcement rule and the Fifth Circuit's narrow two-exception rule.Separate Opinions:Justice Gorsuch (concurring): Traces plea bargaining's coercive growth and catalogues a broader set of miscarriage-of-justice examples, including guideline-calculation errors, while questioning whether prospective appeal waivers can ever satisfy the Constitution's knowing-and-voluntary requirement.Justice Kavanaugh (concurring): Joins the majority in full but writes separately to argue Gorsuch's reading sets a lower bar than the majority opinion actually adopts.Justice Barrett (concurring): Grounds the new rule in "procedural common law" rather than the Court's disputed supervisory power, offering a doctrinal source distinct from the majority's framing.Justice Thomas (dissenting): Dissents alone, arguing the majority cites no genuine source of law for its rule and warns the new standard floods appellate courts with new claims.Implications:(1) Defendants nationwide gain a new, though narrow, path to challenge sentencing errors despite signed appeal waivers;(2) defense attorneys and judges must now weigh whether unusual sentencing conditions risk surviving appellate review;(3) the Fifth Circuit must decide on remand whether Hunter's forced-medication condition clears the new bar.The Fine Print:18 U.S.C. § 3563(b)(9): "undergo available medical, psychiatric, or psychological treatment"Federal Rule of Criminal Procedure 11(c)(3)(A): "[T]he court may accept the agreement, reject it, or defer a decision"Primary Cases:United States v. Mezzanatto (1995): Some baseline of fair procedure survives no matter what a defendant agrees to waive in a plea deal.Santobello v. New York (1971): Plea agreements remain subject to judicial oversight and "sound judicial discretion," not just prosecutorial control.Oral Advocates:For Petitioner: Lisa S. Blatt of Williams & Connolly LLP argued for Petitioner Hunter.For Respondent: Zoe A. Jacoby, Assistant to the Solicitor General, Department of Justice, argued for Respondent United States.
