Hunter “Miscarriage of Justice” Standard: Routine Guidelines Errors (and Downstream Reduction Effects) Do Not Defeat an Appeal Waiver

1. Introduction

United States v. Tovis Richardson (4th Cir. Aug. 20, 2026) is an unpublished per curiam decision on remand from the Supreme Court after a grant-vacate-remand order directing the Fourth Circuit to apply the Supreme Court’s newly announced appeal-waiver framework in Hunter v. United States, 146 S. Ct. 1702 (2026).

Richardson pleaded guilty (pursuant to a written plea agreement) to methamphetamine trafficking offenses under 21 U.S.C. §§ 841(a)(1), 846, and received a 240-month sentence. On direct appeal he challenged (1) a Guidelines firearm enhancement under U.S.S.G. § 2D1.1(b)(1), and (2) alleged ineffective assistance of counsel for failing to object to that enhancement. The Government invoked the plea agreement’s broad appellate waiver.

The key remand issue was narrow but consequential: whether, under Hunter, enforcing Richardson’s otherwise valid appeal waiver would cause a “miscarriage of justice” because an alleged Guidelines error might also affect later eligibility for a newer two-level reduction under U.S.S.G. § 4C1.1 (effective after his plea and asserted to be retroactive).

2. Summary of the Opinion

The Fourth Circuit again affirmed. It held:

  • The appellate waiver remained valid (knowing and intelligent) under existing Fourth Circuit law.
  • The firearm-enhancement challenge fell squarely within the waiver’s scope (waiver of appeal “on any ground,” including guideline-application claims under 18 U.S.C. § 3742).
  • Applying Hunter, Richardson’s alleged sentencing error did not satisfy the “miscarriage of justice” exception because routine misapplications of sentencing law—along with their downstream effects on other Guidelines adjustments—do not overcome an appeal waiver.
  • As to ineffective assistance, the panel adopted its prior reasoning that ineffective assistance did not “conclusively appear” on the record for direct-appeal resolution, leaving the claim for collateral review if appropriate.

3. Analysis

A. Precedents Cited (and How They Shaped the Decision)

1) The remand driver: Hunter v. United States, 146 S. Ct. 1702 (2026)

Hunter supplied the controlling “miscarriage of justice” framework governing when an otherwise enforceable appeal waiver must yield. Critically, the Supreme Court added a limiting principle: “Standard-fare errors in misapplying sentencing law cannot cancel an appeal waiver.” The Court also offered non-exclusive examples of waiver-defeating errors that would “bring the judiciary into disrepute,” including:

  • Statutory illegality (e.g., a prison term exceeding the statutory maximum).
  • Blatant constitutional error (e.g., reliance on race; or an unconstitutional supervised-release condition).
  • Fundamental procedural breakdown (sentencing without a minimum of “civilized procedure”).

The Richardson panel treated these guideposts as a high-bar filter. Because Richardson’s claim was, at bottom, a Guidelines dispute (and an argument about the downstream effect on § 4C1.1), it fell within Hunter’s caveat.

2) Fourth Circuit waiver framework: United States v. Carter, 87 F.4th 217 (4th Cir. 2023); United States v. Boutcher, 998 F.3d 603 (4th Cir. 2021); United States v. Beck, 957 F.3d 440 (4th Cir. 2020)

These cases provided the Fourth Circuit’s standard sequencing: where the Government invokes a waiver and has not breached the plea agreement, the court enforces the waiver if it is valid and the issue falls within its scope. Carter also framed the analysis as de novo review, reinforcing that the waiver’s enforceability is a legal question, not a discretionary one.

3) Knowing-and-intelligent validity: United States v. Soloff, 993 F.3d 240 (4th Cir. 2021); United States v. Blick, 408 F.3d 162 (4th Cir. 2005); United States v. McCoy, 895 F.3d 358 (4th Cir. 2018); United States v. Thornsbury, 670 F.3d 532 (4th Cir. 2012)

These authorities supply the “totality of the circumstances” test and the practical Rule 11 benchmark: when a district court questions a defendant about the waiver and the record shows understanding, the waiver is generally valid. The panel noted that its prior validity finding remained undisturbed by Hunter (which addressed miscarriage-of-justice, not baseline validity).

4) Scope via contract principles: United States v. Yooho Weon, 722 F.3d 583 (4th Cir. 2013)

Yooho Weon supports interpreting the waiver using contract principles and enforcing it when “clearly and unambiguously applicable.” In Richardson, the waiver’s breadth (“on any ground,” explicitly referencing appeals “pursuant to 18 U.S.C § 3742”) made the firearm-enhancement claim a paradigmatic waived issue.

5) The pre-Hunter miscarriage doctrine in the Fourth Circuit: United States v. Adams, 814 F.3d 178 (4th Cir. 2016); United States v. Johnson, 410 F.3d 137 (4th Cir. 2005)

These cases established that the Fourth Circuit may decline to enforce a waiver to avoid a miscarriage of justice. Richardson had previously invoked this doctrine to argue that the firearm enhancement should be reviewed notwithstanding the waiver. On remand, the panel re-anchored that inquiry in Hunter’s more specific guidance.

6) Hunter’s illustrative “civilized procedure” references: United States v. Adkins, 743 F.3d 176 (7th Cir. 2014); United States v. Behrens, 375 U.S. 162 (1963)

The Fourth Circuit cited Adkins and Behrens only through Hunter, to illustrate the extreme category of procedural breakdowns that could justify disregarding a waiver. Richardson’s appeal presented nothing of that order.

7) Prior panel opinion: United States v. Richardson, 146 F.4th 394 (4th Cir. 2025)

The remand posture mattered. The panel relied on its prior determinations for all issues not altered by Hunter, especially the ineffective-assistance claim (not resolvable on the direct-appeal record) and the baseline waiver analysis.

B. Legal Reasoning

1) The waiver’s coverage was straightforward

The panel treated the firearm-enhancement challenge as a classic 18 U.S.C. § 3742 “incorrect application of the sentencing guidelines” claim—precisely what a broad waiver “on any ground” is designed to foreclose. This reflects the court’s consistent view that guideline disputes are among the most commonly waived issues in federal plea agreements.

2) Hunter narrows (and clarifies) “miscarriage of justice” for appeal waivers

The decisive move was to classify Richardson’s argument as a routine Guidelines disagreement, even though it was repackaged as an equity/fairness concern about later § 4C1.1 eligibility. The court reasoned that if “standard-fare” sentencing-law errors do not undo a waiver under Hunter, then downstream collateral effects of such errors (like influencing eligibility for a later Guidelines reduction) likewise cannot undo a waiver.

3) The opinion implicitly distinguishes direct appeal from other post-sentencing mechanisms

While Richardson argued that the enhancement might impair access to § 4C1.1, the court did not treat that as transforming the issue into statutory illegality or constitutional defect. The decision signals that waiver doctrine is about appellate review as bargained-for in the plea—not about guaranteeing that later changes in sentencing policy can be leveraged to relitigate waived guideline determinations on direct appeal.

4) Ineffective assistance remains channeled to collateral review

The court reaffirmed a standard direct-appeal principle: ineffective assistance is generally not decided on direct appeal unless it “conclusively” appears in the record. By noting Hunter did not alter that body of law, the panel maintained doctrinal continuity on remand.

C. Impact

  • Higher practical barrier to escaping waivers. After Hunter, defendants in the Fourth Circuit face a clearer message: ordinary Guidelines errors—however consequential—typically remain within the waiver’s bargain.
  • “Downstream effects” arguments are disfavored. Richardson is notable for rejecting the idea that a waived Guidelines issue becomes unwaived because it may affect later eligibility for another Guidelines benefit (here, U.S.S.G. § 4C1.1).
  • Litigation shifts to other avenues. Defendants seeking relief tied to new guideline provisions or retroactivity may need to rely on the specific procedural vehicles that Congress and the Sentencing Commission provide (where available), rather than attempting to reopen waived guideline findings through direct appeal.
  • Plea bargaining leverage and drafting. Prosecutors may cite Richardson/Hunter to argue for predictable enforcement of broad waivers; defense counsel, in turn, may negotiate for express carve-outs where foreseeable guideline changes (or particular enhancements) could be case-dispositive.

4. Complex Concepts Simplified

Appeal waiver
A clause in a plea agreement where the defendant gives up (waives) the right to appeal the conviction and/or sentence, usually with narrow exceptions (commonly ineffective assistance of counsel or prosecutorial misconduct).
Miscarriage of justice (waiver context)
A safety valve allowing a court to ignore a waiver in rare, extreme circumstances. Under Hunter, routine sentencing-law mistakes are not enough; the error must be obvious and egregious in a way that undermines the legitimacy of the proceedings (e.g., illegal sentence above the statutory maximum, blatant constitutional violation, or fundamental procedural collapse).
U.S.S.G. § 2D1.1(b)(1) firearm enhancement
A two-level increase in a drug offense’s Guidelines level when a dangerous weapon was possessed, reflecting increased risk of violence in drug trafficking.
18 U.S.C. § 3742
The federal statute authorizing certain sentencing appeals, including claims that the Guidelines were incorrectly applied. Waivers commonly reference § 3742 to make clear that guideline-application appeals are being surrendered.
U.S.S.G. § 4C1.1 (zero-point offender reduction)
A later-enacted Guidelines provision Richardson argued could reduce his offense level by two points if eligible. The court treated any dispute about eligibility (stemming from a contested enhancement) as still a Guidelines matter—insufficient under Hunter to override a waiver.
Direct appeal vs. collateral review
Direct appeal challenges the judgment immediately after sentencing. Collateral review (e.g., post-conviction proceedings) is a separate process that can address issues like ineffective assistance when the trial record alone is insufficient.

5. Conclusion

On remand, the Fourth Circuit used Hunter v. United States to reaffirm robust enforcement of appellate waivers: ordinary Guidelines disputes—plus their later sentencing consequences—do not meet the “miscarriage of justice” threshold. The decision reinforces that waiver exceptions are reserved for truly extraordinary defects (statutory illegality, blatant constitutional error, or fundamental procedural breakdown), and it signals that arguments premised on later Guidelines developments (such as § 4C1.1) generally will not reopen waived guideline-enhancement challenges on direct appeal.
