Miles v. Bowers: First Step Act Time Credits Accrue From Statutory Sentence Commencement, Not BOP Arrival/Assessment Rules

Introduction

In Miles v. Bowers (1st Cir. Apr. 27, 2026), Arthur Miles—serving a combined 300-month federal sentence—filed a 28 U.S.C. § 2241 habeas petition challenging the Bureau of Prisons’ (“BOP”) refusal to award him First Step Act (“FSA”) earned time credits for work he performed as a jail orderly while housed for about fifteen months in a county jail after his first federal sentencing but before transfer to his designated federal facility (FMC Devens).

The central dispute concerned whether the BOP may categorically deny FSA credit accrual for programming (including qualifying work) performed after sentencing but before (i) arrival at the BOP-designated facility and/or (ii) completion of the inmate’s individualized risk-and-needs assessment. The district court dismissed the petition; the First Circuit vacated and remanded.

Summary of the Opinion

The First Circuit held that:

The BOP regulation tying “sentence commencement” to arrival at the designated BOP facility (28 C.F.R. § 523.42(a)) conflicts with the statutory definition in 18 U.S.C. § 3585(a) and is invalid as applied to FSA accrual.
Completion of the FSA risk-and-needs assessment is not a prerequisite to a prisoner’s entitlement to earn FSA time credits.
The BOP may not treat non-federal housing, standing alone, as a categorical bar to earning credits for otherwise qualifying programming that can be verified.
Miles’ entire fifteen-month post-first-sentencing county-jail period must be considered for potential credit accrual, and the BOP must make an individualized determination.

The court emphasized it was not deciding whether Miles’ particular job duties qualify as an “evidence-based recidivism reduction program” (“EBRR”) or whether credits should be applied toward earlier release later under 18 U.S.C. § 3624(g). It required, instead, that BOP consider eligibility and potential accrual consistent with the statute.

Warden, FCI Berlin, No. 23-cv-007, 2024 WL 4349850 (D.N.H. Sept. 30, 2024): Both were used to reinforce that the statute’s trigger is sentence commencement under § 3585(a), not administrative milestones.
Brenneman v. Salmonson, No. 5:22cv7, 2025 WL 957216 (E.D. Tex. Feb. 25, 2025), R&R approved and adopted, 2025 WL 914352 (E.D. Tex. Mar. 26, 2025): Quoted for a pragmatic remedial frame: courts need not dictate a single administrative method, but BOP cannot categorically render pre-arrival time ineligible by redefining statutory commencement.

Legal Reasoning

1) Statutory “sentence commences” controls; 28 C.F.R. § 523.42(a) cannot rewrite § 3585(a)

The opinion’s first and clearest move is textual: the FSA cross-references commencement of sentence under 18 U.S.C. § 3585(a), which begins when a defendant is “received in custody awaiting transportation to” the official detention facility. The BOP’s regulation, by contrast, starts the clock only when the inmate “arrives” at the designated BOP facility. The court found “no way to reconcile” those phrases and treated the conflict as dispositive—rendering the regulation invalid to the extent it shifts accrual eligibility later than Congress specified.

2) Risk-and-needs assessment is not a prerequisite to earning credits

The court separated two distinct statutory concepts: (a) earning credits under 18 U.S.C. § 3632(d)(4) (“shall earn” for successful participation), and (b) applying credits toward prerelease custody/supervised release mechanisms under 18 U.S.C. § 3624(g), which explicitly relies on periodic reassessments and risk levels.

Because Congress expressly conditioned application of credits on later risk determinations, but did not impose the same condition on accrual, the court rejected the BOP’s attempt to make assessment timing a categorical gatekeeper for earning credits—especially where BOP practice itself sometimes awards credits pre-assessment (e.g., by equivalency determinations or “opt-in” waitlist situations).

3) Non-federal location does not categorically bar accrual where participation can be verified

The court acknowledged the BOP’s practical argument: it may lack contracts or systems to track programming in non-federal facilities. But it treated that as an administrative difficulty, not a statutory carve-out. The FSA’s command that BOP “shall provide” opportunities to participate “throughout [the] entire term of incarceration” (18 U.S.C. § 3621(h)(6)) would be undermined if BOP could house inmates elsewhere after commencement and then disregard qualifying participation solely because of the location. The court therefore required consideration (and, where feasible, verification) rather than categorical denial.

4) Miles’ two-sentencing timeline did not justify splitting the 15-month period

The government argued (late) that the “earliest possible” date was the second sentencing because the county jail time before that was to await trial in the second case. The First Circuit declined to treat the pre- and post-second-sentencing periods differently, reasoning that Miles was still also “awaiting” designation/transport to his federal facility, and that nothing in the record justified excluding the earlier period as outside the FSA’s accrual window once custody on a federal sentence had begun.

Remedial posture: individualized determination, not automatic credit

Importantly, the court did not award credits outright. It required that the BOP (and district court on remand) take “appropriate next steps” to ensure Miles’ work is considered for credits—leaving open factual questions such as whether his orderly work qualifies as an EBRR program or PA and whether it aligns with his criminogenic needs.

Impact

Administrative-law and statutory-construction significance. The decision squarely rejects the BOP’s attempt (via regulation) to shift the statutory start of FSA accrual to “arrival at designated facility.” In the First Circuit, litigants can cite Miles v. Bowers for the rule that statutory “sentence commencement” under § 3585(a) controls FSA accrual eligibility.

Operational consequences for BOP and contract facilities. Because many federal defendants spend post-sentencing time in local jails or other non-designated facilities awaiting designation/transport, the requirement of individualized consideration may push BOP toward: (i) better record-sharing, (ii) clearer equivalency standards for programs/jobs, and (iii) more timely assessments and designations to reduce disputes.

Incentives and fairness. The court’s emphasis on Congress’s incentive structure (credits as motivation to engage early in recidivism-reduction activity) suggests future challenges will scrutinize categorical rules that create “dead zones” during which inmates cannot realistically accrue credits despite being in federal custody post-sentencing.

Litigation roadmap. The opinion identifies four analytic questions (start date, assessment prerequisite, location, commencement in multi-case contexts). Future petitions will likely focus on the remaining fact-intensive issues Miles left open: whether the activity is a qualifying EBRR/PA, whether it is “equivalent,” and what documentation suffices.

Complex Concepts Simplified

FSA “time credits”: Days an eligible federal prisoner can earn by successfully participating in certain programs or activities aimed at reducing recidivism (18 U.S.C. § 3632(d)(4)). These credits may later be applied to shorten time in prison via prerelease mechanisms, but only if additional statutory conditions are met (18 U.S.C. § 3624(g)).
EBRR programs: “Evidence-based recidivism reduction programming,” meaning programs shown (or likely) to reduce reoffending and help successful reentry (18 U.S.C. § 3635(3)). The statute says an EBRR program “may include . . . a prison job” (18 U.S.C. § 3635(3)(C)(xi)), but that does not mean every job automatically qualifies.
Risk-and-needs assessment (“the System”): The process used to assign inmates a recidivism risk level and identify criminogenic needs to guide programming (18 U.S.C. § 3632(a)). Miles holds that this assessment is not a prerequisite to earning credits, though it matters for later decisions about applying them.
“Sentence commences” under 18 U.S.C. § 3585(a): A sentence starts when the defendant is “received in custody” while “awaiting transportation to” the official facility where the sentence will be served. The key point in Miles: this can occur before arrival at the designated BOP facility (e.g., while held in a county jail post-sentencing).
§ 2241 habeas: A procedural mechanism used to challenge the execution of a sentence (such as sentence-credit calculations), rather than the validity of the conviction itself.

Conclusion

Miles v. Bowers establishes, for the First Circuit, a critical FSA accrual principle: earned-time-credit eligibility begins at statutory sentence commencement under 18 U.S.C. § 3585(a), and the BOP may not categorically deny credit accrual because an inmate has not yet arrived at a designated BOP facility, has not yet completed a risk-and-needs assessment, or is housed in a non-federal facility—at least where the inmate’s qualifying participation can be verified and evaluated.

The decision preserves BOP discretion over administration and verification, but insists on fidelity to the statute’s text and incentive structure. On remand, Miles is entitled to an individualized determination of whether his county-jail work qualifies for FSA time credits, rather than a categorical denial based on timing or location.
