Home Detention Must Substitute One-for-One for Imprisonment and Cannot Push Revocation Punishment Beyond § 3583(e)(3)’s Maximum

1. Introduction

United States v. Mariel Watson addresses a recurring remedial question in supervised-release revocations: when a court revokes supervised release and imposes both imprisonment and a condition of supervised release requiring home detention, how do statutory caps limit the combined sanction?

Mariel Watson (defendant-appellant) violated the terms of supervised release soon after leaving prison. The district court revoked his supervised release and imposed 41 months’ imprisonment followed by lifetime supervised release, including 629 days (nearly 21 months) of home detention. Watson argued this combination exceeded the maximum imprisonment term authorized for revocation under 18 U.S.C. § 3583(e)(3) because home detention may be imposed “only as an alternative to incarceration” under 18 U.S.C. § 3563(b)(19).

The central issue on appeal was whether the district court could impose home detention that, when added to the imprisonment term, effectively created a combined confinement-like sanction beyond the statutory maximum term of imprisonment available at revocation.

2. Summary of the Opinion

The Fourth Circuit held that § 3563(b)(19)’s “only as an alternative to incarceration” language requires a one-for-one substitution: a court may impose home detention only to the extent it forgoes an equivalent amount of imprisonment it otherwise had authority to impose. Consequently, the combined total of imprisonment plus home detention may not exceed the maximum imprisonment term authorized by § 3583(e)(3).

Because Watson received 41 months in prison and the revocation maximum under § 3583(e)(3) was 48 months, the district court could impose at most 7 months of home detention as an “alternative” to the remaining available imprisonment. The imposed nearly 21 months of home detention exceeded statutory authority. The court deemed the error clear and vacated and remanded for resentencing.

3. Analysis

3.1 Precedents Cited

• United States v. Hamilton, 986 F.3d 413, 419 (4th Cir. 2021)
  The panel relied on Hamilton for the general proposition that district courts have “substantial discretion” in setting supervised-release conditions—but emphasized that discretion must “yield to clear congressional commands.” This framed the decision as statutory fidelity, not a policy dispute over how punitive home detention should be.
• United States v. Ward, 171 F.3d 188, 191 (4th Cir. 1999)
  Ward was invoked alongside the Rule 35 advisory note to define “clear error” as the kind of obvious mistake likely to result in remand. This supported treating Watson’s reconsideration request as a Rule 35(a) motion and justified correction where the sentence rested on a mistaken view of statutory authority.
• United States v. Ferguson, 369 F.3d 847, 850 (5th Cir. 2004) (per curiam)
  The Fourth Circuit aligned with Ferguson, which held that “incarceration and home detention are alternative punishments that may not combine in excess of the maximum statutory term of incarceration.” The opinion treated this as persuasive confirmation that the “alternative” language imposes a real ceiling.
• United States v. Hall, 64 F.4th 1200, 1205-06 (11th Cir. 2023)
  Hall provided a closely analogous interpretation: home confinement is “as an alternative to incarceration” only when the court has authority to impose imprisonment but chooses home confinement instead. The Fourth Circuit also cited Hall to distinguish Fourth Circuit precedent (Hager) that addressed a different question.
• United States v. Leaphart, 98 F.3d 41, 43 (2d Cir. 1996)
  Cited as reaching a similar conclusion under the sentencing guidelines, Leaphart bolstered the cross-jurisdictional consensus that home detention functions as a substitute for confinement rather than a limitless add-on to imprisonment.
• United States v. Marcano, 525 F.3d 72, 73-74 (1st Cir. 2008) (per curiam)
  The panel noted Marcano approvingly referenced Ferguson, reinforcing that multiple circuits converge on the same conceptual framework for “alternative” sanctions.
• United States v. Hager, 288 F.3d 136 (4th Cir. 2002)
  The district court relied on Hager to treat home detention as wholly distinct from imprisonment for purposes of the revocation maximum. The Fourth Circuit rejected that reliance as a category mistake: Hager decided whether already-served home detention counts as imprisonment under § 3583(e)(3) at a later revocation; it did not decide whether home detention can be imposed beyond the remaining imprisonment authority given § 3563(b)(19)’s “alternative” limitation. The panel thus preserved Hager while limiting its reach.

3.2 Legal Reasoning

The court’s reasoning is a straightforward textual synthesis of two statutes:

• 18 U.S.C. § 3583(e)(3) caps the maximum term of imprisonment a court may impose upon revocation (here, 48 months).
• 18 U.S.C. § 3563(b)(19) authorizes home detention as a supervised-release condition, but only “as an alternative to incarceration.”

The panel treated “alternative” in its ordinary sense—“a choice between two things wherein if one thing is chosen the other is rejected”—and reasoned that an “alternative to incarceration” must displace incarceration the court otherwise could have ordered. If the court lacks authority to impose additional imprisonment (because it has reached the § 3583(e)(3) maximum), then any extra home detention is no longer an “alternative”; it becomes an additional deprivation layered on top of the maximum imprisonment.

The court also rejected the government’s proposed approach that would allow a court to impose any amount of home detention so long as it did not impose the imprisonment maximum (suggesting, for example, that nearly 21 months of home detention could substitute for 7 months of unused imprisonment). The panel found this inconsistent with the statutory text because it lacked any limiting principle—potentially permitting extraordinarily long (even lifetime) home detention as an “alternative” to a trivial amount of unused imprisonment.

Procedurally, the panel characterized Watson’s “motion for reconsideration” as a Rule 35(a) motion to correct “arithmetical, technical, or other clear error,” and held the legal mistake was sufficiently clear to require correction.

3.3 Impact

This published Fourth Circuit opinion establishes a clear constraint on revocation sentencing practice within the circuit:

• Ceiling on combined sanctions: When home detention is imposed under § 3563(b)(19) after revocation, its duration is limited by the remaining imprisonment authority under § 3583(e)(3). Courts must effectively “budget” home detention out of the statutory imprisonment cap.
• One-for-one substitution requirement: Courts may not use home detention as a flexible “multiplier” that converts a small amount of unused imprisonment authority into a much larger period of home confinement.
• Clarification of Hager’s scope: The decision prevents litigants from reading United States v. Hager to mean home detention can always be stacked on top of imprisonment without regard to § 3563(b)(19). Hager remains good law on a different question (whether home detention counts as imprisonment under § 3583(e)(3)), but it does not authorize additive home detention beyond the imprisonment maximum.
• Sentencing uniformity: The Fourth Circuit joins the approach taken by other circuits (Ferguson, Hall) and strengthens national uniformity on the “alternative to incarceration” limitation.

Practically, the decision will affect revocation negotiations and sentencing recommendations: parties and probation offices must calculate home detention as consuming the same amount of the statutory revocation “incarceration capacity” that the court elects not to impose.

4. Complex Concepts Simplified

• Supervised release: A period of court-ordered monitoring after prison. Violations can lead to “revocation” and additional penalties.
• Revocation (of supervised release): If the defendant violates release conditions, the court can revoke release and impose imprisonment and a new term of supervised release.
• Statutory maximum under § 3583(e)(3): Congress caps how much imprisonment a court may impose for a revocation (here, 48 months). A court cannot exceed that cap.
• Home detention under § 3563(b)(19): Confinement to the home (typically monitored) that can be imposed as a supervised-release condition, but only as a substitute for imprisonment.
• “Alternative to incarceration” (as used here): Not “in addition to,” but “instead of”—and, per this opinion, on a one-for-one time basis.
• Rule 35(a) clear error: A narrow mechanism allowing prompt correction of obvious sentencing mistakes—here, a mistaken view of what the statute authorizes.

5. Conclusion

United States v. Mariel Watson announces a concrete rule for revocation sentencing in the Fourth Circuit: because home detention may be imposed “only as an alternative to incarceration,” a court may impose home detention only to the extent it forgoes the same amount of imprisonment it could have imposed under § 3583(e)(3). The decision preserves United States v. Hager while preventing it from being misread to permit additive home detention. By vacating and remanding, the Fourth Circuit reinforces that supervised-release discretion is substantial but not unbounded—and that statutory text supplies enforceable limits.
