Anders Review After Resentencing: The Mandate Rule Limits Which Issues May Be Reopened

1. Introduction

This case concerns the scope of appellate review after a defendant successfully obtains resentencing without an Armed Career Criminal Act enhancement. Marquis Quinzel Mack originally received a fifteen-year prison sentence for possessing a firearm after a felony conviction. Following an intervening Supreme Court decision concerning the jury’s role in ACCA sentencing, the Fourth Circuit remanded his case for resentencing without that enhancement. The district court then imposed an eighty-six-month prison term.

On the second appeal, Mack’s counsel filed a brief under Anders v. California, reporting no meritorious appellate grounds but requesting review of the sentence’s procedural and substantive reasonableness. The appeal therefore presented an important procedural question: does counsel’s request for independent review reopen the entire original prosecution, or does the earlier appellate mandate still restrict which issues may be considered?

The Fourth Circuit applied the mandate rule to limit its review to issues raised in Mack’s original appeal and the resentencing proceedings. It rejected his preserved constitutional challenge to the conviction under binding circuit authority and upheld the new sentence.

2. Background and Procedural History

1. Indictment and guilty plea. A September 26, 2022 superseding indictment charged Mack with possessing a firearm after a felony conviction under 18 U.S.C. §§ 922(g)(1) and 924(e). He pleaded guilty without a plea agreement in November 2022.
2. Original sentence. The district court treated Mack as an armed career criminal and imposed 180 months’ imprisonment, followed by three years of supervised release with special conditions.
3. First appeal. Mack challenged the judicial determination supporting the ACCA enhancement, the classification of his North Carolina conviction for burning personal property as an ACCA violent felony, and the constitutionality of § 922(g)(1) as applied to him.
4. Intervening Supreme Court decision. In Erlinger v. United States, the Supreme Court held that ACCA’s “different occasions” determination must be made by a jury beyond a reasonable doubt or freely admitted by the defendant in a guilty plea.
5. Remand and resentencing. On the Government’s unopposed motion, the Fourth Circuit remanded for resentencing without ACCA. The revised calculation produced offense level 23, criminal history category IV, and an advisory imprisonment range of 70 to 87 months. The opinion identifies the applicable statutory maximum as ten years. The district court imposed eighty-six months and retained the three-year supervised-release term and its conditions.
6. Second appeal. Counsel filed an Anders brief. The Government declined to respond, and Mack did not submit a supplemental brief despite notice of his right to do so. The court independently reviewed the relevant record and affirmed.

3. Summary of the Opinion

The court reached four principal conclusions:

• The mandate rule constrained independent review. An Anders appeal following remand did not permit Mack to introduce challenges that could have been raised in his initial appeal but were not.
• The original ACCA disputes were moot. Resentencing without ACCA had removed the enhancement that those arguments challenged.
• The conviction remained valid. Binding Fourth Circuit precedent foreclosed Mack’s as-applied Second Amendment challenge to § 922(g)(1).
• The new sentence was reasonable. The district court correctly calculated the Guidelines range, followed the required sentencing procedures, adequately explained its decision, and imposed a substantively reasonable sentence.

The court also found no error concerning the discretionary supervised-release conditions and no other potentially meritorious appellate issue within the permissible scope of review.

4. Analysis of the Precedents Cited

A. Independent Review and the Limits Imposed by an Earlier Appeal

Anders v. California, 386 U.S. 738 (1967)

This decision supplies the framework for an appeal in which appointed counsel concludes that no meritorious grounds exist. Counsel’s assessment does not itself end the appeal: the appellate court must independently examine the appropriate record. Mack’s counsel invoked this procedure while identifying sentencing reasonableness as a possible issue.

Penson v. Ohio, 488 U.S. 75, 80 (1988)

The court cited Penson v. Ohio for the general obligation to examine the proceedings fully before determining that an appeal is wholly frivolous. Its importance here is the apparent breadth of that duty. The Fourth Circuit explained that independent review still operates within the procedural boundaries established by the earlier appeal and remand.

Fusaro v. Howard, 19 F.4th 357, 367 (4th Cir. 2021)

This case states the law-of-the-case principle: a legal issue decided at one stage ordinarily continues to govern later stages of the same litigation. It supplied the general finality principle underlying the court’s more specific mandate analysis.

Volvo Trademark Holding Aktiebolaget v. Clark Mach. Co., 510 F.3d 474, 481 (4th Cir. 2007)

This precedent identifies the mandate rule as a specific application of law of the case to proceedings following an appellate remand. It connected the general doctrine to Mack’s procedural posture.

United States v. Bell, 5 F.3d 64, 66 (4th Cir. 1993)

The court relied on this decision for two related propositions: proceedings after remand are confined by the appellate mandate, and issues expressly or implicitly resolved on appeal may not be relitigated. Resentencing therefore does not automatically reopen every aspect of a criminal case.

United States v. Susi, 674 F.3d 278, 283 (4th Cir. 2012)

This authority extends the mandate rule to issues decided in the district court but abandoned on appeal or otherwise waived. Its role was to prevent review from expanding merely because a defendant obtained relief on a separate sentencing question.

Doe v. Chao, 511 F.3d 461, 465 (4th Cir. 2007)

This decision supports treating an issue that could have been raised in an earlier appeal, but was not, as waived and outside the remand. It reinforces the distinction between preserved issues and previously available but omitted claims.

Omni Outdoor Adver., Inc., v. Columbia Outdoor Adver., Inc., 974 F.2d 502, 505 (4th Cir. 1992)

The court cited this case for the impropriety of considering, in a second appeal after remand, an argument available during the first appeal. It demonstrates that the governing finality principle extends beyond criminal sentencing cases.

Edd Potter Coal Co., Inc. v. Dir., Off. of Workers' Comp. Programs, United States Dep't of Lab., 39 F.4th 202, 210 (4th Cir. 2022)

This decision supplied the court’s clearest explanation of the rule’s purpose: a party cannot use the “accident of a remand” to raise an issue that could equally have been presented earlier. The Fourth Circuit applied that reasoning to define the permissible scope of its Anders review.

Together, these authorities establish the opinion’s central procedural lesson: independent appellate scrutiny does not erase the consequences of an earlier appeal. The court did not discuss possible exceptions to the mandate rule, so its decision should not be read as resolving when an exceptional departure might be justified.

B. ACCA, the Remand, and Mootness

Erlinger v. United States, 602 U.S. 821, 833–35 (2024)

This decision caused the change in Mack’s sentencing posture. It requires jury determination beyond a reasonable doubt—or the defendant’s free admission in a guilty plea—that the relevant ACCA offenses occurred on different occasions.

Its scope matters. The decision concerns the “different occasions” finding; the Mack opinion does not hold that every question about a prior conviction or its legal classification must be submitted to a jury. Following Erlinger v. United States, the Government requested resentencing without ACCA, and the Fourth Circuit granted that relief.

United States v. Fluker, 891 F.3d 541, 551 (4th Cir. 2018)

The court cited this case by comparison when explaining mootness. A sentencing claim remains live when an identifiable consequence can still be corrected through appellate relief. Mack’s two original ACCA arguments no longer presented such an issue because the enhancement had already been removed.

Accordingly, the court did not decide whether North Carolina burning personal property qualifies as an ACCA violent felony. Treating this opinion as resolving that classification would mistake a mootness disposition for a merits holding.

The procedural history also references United States v. Erlinger, No. 23-370, the Supreme Court matter as identified while pending, and the Fourth Circuit matters United States v. Trevor Allen Boggs, No. 22-4707, and United States v. Rico Brown, No. 21-4253. These references explain why the original appeal was held in abeyance. The opinion attributes no substantive holding to the latter two matters.

C. The Second Amendment Challenge

New York State Rifle & Pistol Ass'n v. Bruen, 597 U.S. 1 (2022)

Mack invoked this decision to argue that § 922(g)(1) could not constitutionally be applied to him without a factual showing that he was dangerous. He framed the alleged defect as a reason the district court should not have accepted his guilty plea. The panel did not undertake a fresh historical analysis because controlling circuit authority already resolved the relevant issue.

United States v. Hunt, 123 F.4th 697, 702 (4th Cir. 2024)

This was the decisive authority. It held that neither New York State Rifle & Pistol Ass'n v. Bruen nor United States v. Rahimi, 602 U.S. 680 (2024), displaced Fourth Circuit precedent foreclosing as-applied challenges to § 922(g)(1). The opinion notes that certiorari in United States v. Hunt was denied.

The panel therefore rejected Mack’s proposed individualized-dangerousness requirement under binding circuit law rather than creating a new constitutional test.

United States v. Canada, 123 F.4th 159, 161 (4th Cir. 2024)

This decision supplied supporting authority that § 922(g)(1) is facially constitutional because it has a plainly legitimate sweep and constitutionally applies in at least some circumstances. Its role should be distinguished from that of United States v. Hunt: facial validity does not by itself answer every as-applied argument, but the latter precedent directly foreclosed Mack’s challenge.

The citation to United States v. Mack, Appeal No. 23-4763, identifies Mack’s earlier briefing and the argument preserved there; it is not a separate substantive precedent.

D. Sentencing Review

United States v. McCoy, 804 F.3d 349, 351 (4th Cir. 2015), and Gall v. United States, 552 U.S. 38 (2007)

These authorities establish deferential abuse-of-discretion review. Gall v. United States also supplies the two-part inquiry: first examine sentencing procedure, then assess substantive reasonableness.

United States v. Lynn, 592 F.3d 572, 575–76 (4th Cir. 2010)

This decision supports plain-error review for unpreserved, nonstructural sentencing errors and identifies procedural requirements, including consideration of sentencing arguments and an adequate explanation. The panel stated this framework without identifying a particular unpreserved error warranting relief.

United States v. Provance, 944 F.3d 213, 218 (4th Cir. 2019)

This case requires procedural review to precede substantive review. The sequence prevents a seemingly acceptable sentence length from curing an improper sentencing process.

United States v. Nance, 957 F.3d 204, 212 (4th Cir. 2020)

This authority directs substantive review toward the totality of the circumstances and asks whether the district court abused its discretion in concluding that the sentence satisfied § 3553(a).

United States v. Gillespie, 27 F.4th 934, 945 (4th Cir. 2022)

This case provides the appellate presumption of substantive reasonableness for a sentence within or below a properly calculated Guidelines range. Mack’s eighty-six-month sentence fell within the seventy-to-eighty-seven-month range and therefore received that presumption.

United States v. Bennett, 986 F.3d 389, 401 (4th Cir. 2021)

This precedent explains how a defendant can rebut the presumption: by showing that the sentence is unreasonable when measured against the § 3553(a) factors. Mack made no such showing, and independent review disclosed none.

United States v. Friend, 2 F.4th 369, 379 (4th Cir. 2021)

This decision requires an explanation sufficient to demonstrate consideration of the parties’ arguments and a reasoned basis for the sentencing choice. The panel found that Mack’s resentencing met that standard.

United States v. Singletary, 984 F.3d 341, 345 (4th Cir. 2021)

This authority addresses discretionary supervised-release conditions appearing for the first time in a written judgment: such conditions have not actually been imposed on the defendant. The panel found no corresponding error here. Because the opinion does not reproduce the conditions or analyze their individual restrictions, it offers limited guidance about their substantive validity in other cases.

5. The Court’s Legal Reasoning

A. Defining the Reviewable Record

The court first reconciled two obligations: independently protecting Mack’s appellate rights under Anders and respecting the finality imposed by the earlier appeal. It reviewed the original issues and the resentencing, but did not reopen unrelated claims that could have been presented previously.

This was not a rule that only sentencing matters could be considered. Mack’s previously raised constitutional challenge remained within the court’s review. By contrast, his original ACCA arguments no longer required decision because the remand had already eliminated that enhancement.

B. Applying Binding Constitutional Authority

The panel then resolved the preserved challenge to § 922(g)(1) through circuit precedent. Under United States v. Hunt, Mack’s reliance on intervening Supreme Court Second Amendment decisions did not displace the governing prohibition on his as-applied challenge. His argument that the plea required a separate governmental showing of dangerousness consequently failed.

The reasoning is deliberately narrow: the panel applied an existing circuit rule rather than independently deciding the full historical scope of firearm restrictions on persons with felony convictions.

C. Reviewing the Resentencing Process

The court verified offense level 23 and criminal history category IV under the cited provisions of the 2021 Guidelines Manual, including §§ 2K2.1(a)(2), 2K2.1(b)(4)(A), and 3E1.1(a)–(b). It also confirmed that the district court:

• Treated the Guidelines as advisory rather than mandatory;
• Allowed both sides to argue for an appropriate sentence;
• Allowed Mack to address the court personally;
• Considered the relevant § 3553(a) factors; and
• Adequately explained the selected sentence.

The opinion does not provide a detailed account of the district court’s individual sentencing considerations. Its holding is that the record supplied an adequate explanation, not that a particular aggravating circumstance independently required eighty-six months.

D. Reviewing the Sentence’s Length

After finding no procedural defect, the panel applied the presumption of substantive reasonableness. Although eighty-six months was near the top of the advisory range, that placement alone did not establish an abuse of discretion. Neither Mack’s submissions nor the court’s independent examination revealed a basis to conclude that the sentence was unreasonable under § 3553(a).

6. Potential Impact and Limits

• First appeals remain consequential. Defendants must identify available challenges at the initial appellate stage; later sentencing relief ordinarily does not create a new opportunity to litigate omitted issues.
• Anders review remains bounded. Counsel’s inability to identify a meritorious issue triggers judicial scrutiny, but not an unrestricted reopening of the prosecution.
• ACCA relief can substantially change sentencing exposure. Mack’s imprisonment fell from 180 to 86 months. Nevertheless, removing ACCA did not remove all Guidelines consequences associated with his criminal history.
• Mootness can leave substantive questions unresolved. The decision does not classify North Carolina burning personal property under ACCA and should not be cited as resolving that question.
• Second Amendment outcomes depend on controlling circuit authority. The panel’s disposition illustrates the importance of identifying whether an intervening Supreme Court decision has actually displaced existing circuit law.
• Sentencing explanation remains essential. A within-Guidelines sentence receives favorable substantive review only after the court verifies the calculation and the sentencing process.

Because the opinion is unpublished, these points are principally illustrative and persuasive. The binding legal rules arise from the published precedents the panel applied.

7. Complex Concepts Simplified

ACCA enhancement

A sentencing provision imposing a fifteen-year minimum for a qualifying firearm offender with the required prior convictions committed on different occasions.

Different occasions

The requirement that qualifying prior offenses occurred on separate occasions. Under the Supreme Court decision applied here, the necessary finding belongs to a jury unless freely admitted in a guilty plea.

Anders brief

A filing by counsel who finds no meritorious appellate grounds, allowing the court to examine the record independently rather than simply accepting counsel’s conclusion.

Mandate rule

The principle that proceedings following an appeal must respect what the appellate court decided and the scope of what it sent back.

Mootness

A claim is moot when a decision on it can no longer provide meaningful relief. Mack’s ACCA challenges became moot after that enhancement was removed.

Facial versus as-applied challenge

A facial challenge attacks a statute’s general validity; an as-applied challenge argues that applying it to a particular person or situation is unconstitutional.

Procedural versus substantive reasonableness

Procedural review asks whether the judge used the correct process. Substantive review asks whether the resulting sentence is reasonable in the circumstances.

Section 3553(a) factors

The statutory considerations guiding federal sentencing, including the offense, the defendant’s history, deterrence, public protection, and avoiding unwarranted disparities.

Allocution

The defendant’s opportunity to speak personally before sentence is imposed.

8. Conclusion

The Fourth Circuit affirmed Mack’s conviction and his reduced sentence of eighty-six months’ imprisonment followed by three years of supervised release. Its central lesson is procedural: resentencing and Anders review do not erase the limits created by an earlier appeal.

The opinion also carefully separates relief already obtained from issues still requiring decision. ACCA’s removal mooted the original enhancement disputes; binding circuit precedent defeated the preserved Second Amendment challenge; and ordinary sentencing-review principles sustained the amended judgment. Its significance is a disciplined application of established law, not the creation of a new binding rule.
