SUMMARY *
Habeas Corpus
The panel reversed the district court’s order denying
Leon Gonzalez’s petition for a writ of habeas corpus under
28 U.S.C. § 2241 and remanded with instructions to grant
the petition in part, direct the government to recalculate
Gonzalez’s earned time credits under the First Step Act of
2018, and provide the recalculation to his probation officer.
Gonzalez was on supervised release after serving his
custodial sentence, and he had earned First Step Act time
credits for participating in recidivism reduction programs
while in prison and on home confinement. The government
argued that his credits could not be used to reduce the length
of his term of supervised release.
The panel held that the plain language of the First Step
Act and the relevant canons of construction clearly
demonstrated that Congress created the Act’s time credit
scheme to allow for the reduction in length of a supervised
release term.

OPINION
MENDOZA, Circuit Judge:
The First Step Act of 2018 (“FSA”) was transformative
law with far-reaching implications that have yet to all be
realized. Pub. L. No. 115-391, 132 Stat. 5194 (2018). This
case concerns one such implication: a system to incentivize
incarcerated individuals to complete programs intended to
reduce their risk of recidivism. As part of this system,
Congress created “[t]ime credits” that “shall be applied
toward time in prerelease custody or supervised release.” 18
U.S.C. § 3632(d)(4)(C).
Petitioner Leon Gonzalez served his custodial sentence.
He is now on supervised release and sitting on a heap of FSA
time credits that he asks to be applied to reduce the term of
his supervised release. The Government argues that those
credits are worth nothing—that the time and energy
4 GONZALEZ V. HERRERA
Gonzalez spent earning credits in excess of his custodial
sentence is wasted. We disagree. The plain language of the
law and the relevant canons of construction clearly
demonstrate that Congress created the FSA’s time credit
scheme to allow for the reduction in length of a supervised
release term in Gonzalez’s circumstances. Therefore, we
reverse the order dismissing Gonzalez’s petition for writ of
habeas corpus and remand with further instructions.
I.
On September 26, 2016, Gonzalez appeared for
sentencing on a conviction for conspiracy to distribute
controlled substances. Dkts. 940, 941, United States v.
Gonzalez, 14-cr-684-CAS-33 (C.D. Cal. Sept. 26, 2016).
The district court sentenced Gonzalez to 120 months of
imprisonment and five years of supervised release. Id. Upon
the commencement of his sentence, Gonzalez was placed in
a medium-security Bureau of Prisons (“BOP”) facility.
Two years into Gonzalez’s sentence, Congress enacted
the FSA. 132 Stat. 5194. Along with a host of other reforms,
the FSA directed the Attorney General to create a “risk and
needs assessment system” aimed at reducing prisoner
recidivism. Id. at 5196. Congress instructed the Attorney
General to evaluate each prisoner for evidence-based
recidivism reduction programming, assign them to
appropriate programs, and offer incentives for participation.
Id. at 5196–97. Congress listed specific incentives including
phone and visitation privileges, transfers to another
institution, increased commissary, and the big one—time
credits. Id. at 5197–98. Under Congress’s design, prisoners
can earn up to 15 days of time credits for every 30 days of
participation in recidivism reduction programs or productive
activities, depending on their risk level assessments. Id. at
GONZALEZ V. HERRERA 5
5198. Prisoners could start earning time credits on the date
of the FSA’s enactment. Id.; see also 28 C.F.R. § 523.42(b)
(BOP’s implementing regulations of the FSA).
Gonzalez took advantage of the program’s educational
benefits, and as a result, began accruing earned time credits.
He participated in classes for business marketing, ceramics,
nutrition, leather garment making, and math. On July 24,
2019, the BOP moved him to FCI Lompoc, a low-security
facility. Then the COVID-19 pandemic swept through the
prison population, along with the rest of the country.
On March 27, 2020, Congress responded to the COVID-
19 pandemic with the Coronavirus Aid, Relief, and
Economic Security Act (“CARES Act”). Pub. L. No. 116-
136, 134 Stat. 281 (2020). The CARES Act allowed the
BOP to place a prisoner on home confinement prior to
release earlier than usual. 134 Stat. 516. The BOP did so
for Gonzalez on November 19, 2020. See Office of the
Attorney General, Memorandum for Director of Bureau
Prisons, Prioritization of Home Confinement as Appropriate
in Response to COVID-19 Pandemic (Mar. 26, 2020),
available at
https://www.bop.gov/news/pdfs/20200405_covid-
19_home_confinement.pdf (last visited July 24, 2025)
(explaining that the BOP director shall evaluate prisoners for
home confinement based upon criteria including
vulnerability to COVID-19, the inmate’s conduct, the
inmate’s recidivism risk score, and more).
While on home confinement, Gonzalez lived with his
sister and mother in Montebello, California, and reported to
a halfway house in El Monte, California. Not wanting to
stay idle, Gonzalez continued his FSA-eligible
programming. He got a barbering license and a trucking
6 GONZALEZ V. HERRERA
permit, and he took electrician and machine-shop courses.
Gonzalez’s odyssey toward rehabilitation is remarkable and,
having earned time credits along the way, he sought to use
those credits for early reentry into society.
Respondent Juan Herrera, Residential Reentry Manager
for the Long Beach Residential Reentry Management field
office (“RRM”), oversaw Gonzalez while he was on home
confinement. Nearing the end of his term of imprisonment,
in April 2022, Gonzalez emailed and mailed a letter to
Herrera, requesting information about his earned time
credits. Herrera did not respond to Gonzalez’s request.
Luckily, the Federal Public Defender’s office contacted the
BOP on Gonzalez’s behalf and asked for Gonzalez’s release
date to account for his earned time credits. In July 2023, a
BOP supervising attorney responded, claiming that the BOP
had no record of an administrative remedy request. The next
day, Gonzalez completed an administrative remedy form,
requesting reevaluation of his PATTERN score 1 and
recalculation of his earned time credits. He mailed the form
to his RRM and a BOP administrative office. Once more,
no response. As a result, Gonzalez then submitted a
“regional administrative remedy appeal” form, asking for the
same relief. Gonzalez yet again received no response from
1
The BOP calculates recidivism risk through a “Prisoner Assessment
Tool Targeting Estimated Risk and Needs” score. BOP, PATTERN Risk
Assessment, available at https://www.bop.gov/inmates/fsa/pattern.jsp
(last visited July 24, 2025). Gonzalez’s score was 32, which the BOP
marked as “medium” risk, though Gonzalez argues that under a newer
version of the PATTERN system, he should have been “low” risk.
Gonzalez’s score determines how many credits he accrues for each day
of participation in risk reduction activities. 18 U.S.C. § 3632(d)(4)(A).
Because the parties agree on the number of earned time credits that
Gonzalez ultimately accrued, we consider the discrepancy no further.
GONZALEZ V. HERRERA 7
the BOP, and so he completed a “central office
administrative remedy appeal” form, which he mailed to the
BOP’s national office in Washington, D.C. Unsurprisingly,
the BOP never responded to Gonzalez’s administrative
appeals. Instead, the record indicates that on November 27,
2023, the BOP closed his remedy request, with an internal
note remarking, “since you are on home confinement, you
need to begin your appeal with the RRM.”
After a fruitless attempt to go through the BOP’s
administrative process, and having exhausted his
administrative remedies, Gonzalez reached for his last resort
and filed his petition for habeas corpus pursuant to 28 U.S.C.
§ 2241 against Herrera and the BOP director (collectively
“the Government”). When he filed his petition, his release
date was calculated as September 26, 2024. He petitioned to
have his earned time credits applied to end his home
confinement and for his remaining earned time credits to be
applied to reduce the length of his supervised release term.
On February 2, 2024, while Gonzalez’s habeas petition
was pending, the BOP released him from custody, applying
237 of his 610 days of earned time credits to end his
custodial sentence. This leaves Gonzalez with 373 days of
unused earned time credits. The Government filed an
opposition to his habeas petition a week later, arguing that
insofar as Gonzalez’s petition sought an end to his custodial
sentence, his request was moot and that his earned time
credits cannot reduce the length of his term of supervised
8 GONZALEZ V. HERRERA
release. On April 2, 2024, the district court dismissed his
petition. 2 Gonzalez appeals.
II.
We have jurisdiction over a district court’s denial of a
habeas corpus petition pursuant to 28 U.S.C. §§ 1291 and
2253. We review the denial of a habeas corpus petition and
questions of statutory interpretation de novo. Bottinelli v.
Salazar, 929 F.3d 1196, 1198–99 (9th Cir. 2019) (citing
Stephens v. Herrera, 464 F.3d 895, 897 (9th Cir. 2006) and
Chemehuevi Indian Tribe v. Newsom, 919 F.3d 1148, 1151
(9th Cir. 2019)). 3
III.
A thin slice of the United States Code controls this case.
18 U.S.C. § 3632 codifies the FSA’s mandate for a risk and
needs assessment system, subsection (d) provides incentives
for prisoners to participate, and subsubsection (4) creates
earned time credits. Subsubsubsection (C) is entitled
2
On February 18, 2025, Gonzalez moved for early termination of
supervised released in his criminal case, arguing in part that his
sentencing judge should consider his earned time credits. Dkt. 2419,
Gonzalez, 14-cr-684-CAS-33 (C.D. Cal. Feb. 18, 2025). His sentencing
judge denied his motion on March 24, 2025. Dkt. 2461, Gonzalez, 14-
cr-684-CAS-33 (C.D. Cal. Mar. 24, 2025). He appealed, which is Ninth
Circuit Case No. 25-2245.
3
Gonzalez’s release from the custody of the BOP does not moot his
petition, as he still seeks relief from supervised release. See Mujahid v.
Daniels, 413 F.3d 991, 994 (9th Cir. 2005) (“[A] habeas petitioner
remains in the custody of the United States while on supervised
release.”).
GONZALEZ V. HERRERA 9
“[a]pplication of time credits toward prerelease custody or
supervised release,” and reads:
Time credits earned under this paragraph by
prisoners who successfully participate in
recidivism reduction programs or productive
activities shall be applied toward time in
prerelease custody or supervised release. The
Director of the Bureau of Prisons shall
transfer eligible prisoners, as determined
under section 3624(g), into prerelease
custody or supervised release.
18 U.S.C. § 3632(d)(4)(C).
Divergent interpretations of this language have led
litigants and courts to opposing conclusions concerning its
effect. Some courts have reasoned that “[a]pplying credits
toward something ordinarily means reducing that thing,” and
therefore the FSA “allows credits to be applied to reduce a
term of (i.e., ‘time in’) . . . supervised release[.]” Rivera-
Perez v. Stover, 757 F. Supp. 3d 204, 211–12 (D. Conn.
2024); see also Dyer v. Fulgam, 21-CV-299, 2022 WL
1598249, at *3 (E.D. Tenn. May 20, 2022). Others have held
that to apply earned time credits “toward time in . . .
supervised release” means to “bring an inmate closer to . . .
supervised release by reducing their time in prison.” United
States v. Doost, 22-CR-4466, 2024 WL 2064062, at *3–4
(N.D. Cal. May 7, 2024). Under their reasoning, earned time
credits can shorten a custodial sentence and no more. Id.;
see also Guerriero v. Miami RRM, 24-10337, 2024 WL
2017730, at *2 (11th Cir. May 7, 2024) (per curiam); United
States v. Calabrese, 11-CR-437, 2023 WL 1969753, at *2–
4 (N.D. Ohio Feb. 13, 2023).
10 GONZALEZ V. HERRERA
Splits in authority are seldom so stark and consequential,
but we have little difficulty reaching a conclusion. From the
plain text and canons of construction, it is clear that
Congress intended for the FSA’s earned time credits to
reduce a prisoner’s supervised release term. To conclude
otherwise, as the Government urges us to do, would require
bending and twisting the statutory language and reading
incongruence into criminal statutes. We decline to do so and
instead rest upon a reading coherent with the plain text
inquiry and context.
A.
“When interpreting a statute, we look first to its text.”
Ileto v. Glock, Inc., 565 F.3d 1126, 1133 (9th Cir. 2009)
(citing Robinson v. Shell Oil Co., 519 U.S. 337, 340 (1997)).
We must “‘generally give words their ordinary,
contemporary, common meaning.’” United States v.
Korotkiy, 118 F.4th 1202, 1210 (9th Cir. 2024) (quoting
Pakootas v. Teck Cominco Metals, Ltd., 830 F.3d 975, 980
(9th Cir. 2016)). “If the ‘statutory text is plain and
unambiguous[,]’ we ‘must apply the statute according to its
terms.’” Guido v. Mount Lemmon Fire Dist., 859 F.3d 1168,
1170 n.1 (9th Cir. 2017), aff’d, 586 U.S. 1 (2018) (quoting
Carcieri v. Salazar, 555 U.S. 379, 387 (2009)). But “‘[i]f
the statute’s terms are ambiguous, we may use canons of
construction, legislative history, and the statute’s overall
purpose to illuminate Congress’s intent.’” Ileto, 565 F.3d at
1133 (quoting Jonah R. v. Carmona, 446 F.3d 1000, 1005
(9th Cir. 2006)); see also Korotkiy, 118 F.4th at 1210 (“[W]e
must rifle through our ‘legal toolkit’ and ‘carefully consider
the text, structure, history, and purpose’ of the regulation to
derive its meaning.” (cleaned up) (quoting Kisor v. Wilkie,
588 U.S. 558, 575 (2019))).
GONZALEZ V. HERRERA 11
We begin with the dictionary. See United States v.
Flores, 729 F.3d 910, 914 (9th Cir. 2013). Most of the
linguistic wrestling in this dispute concerns the meaning of
toward, which the statute (understandably) leaves
undefined. Those arguing that Congress meant for earned
time credits to bring supervised release closer, rather than
reduce its term, look to definitions of toward such as “in the
direction of,” Toward, Black’s Law Dictionary (10th ed.
2014), or “along a course leading to,” Toward, Webster’s
Third New International Dictionary of the English Language
2417 (2002); see also Toward, Oxford English Dictionary,
https://doi.org/10.1093/OED/4426685120 (last visited July
24, 2025) (“In the direction of, on the way to . . . .”). The
argument then goes that the statute should read, “time credits
shall be applied in the direction of time in supervised
release.” Under this interpretation, time credits are applied
to reduce the time preceding supervised release, rather than
time in supervised release, so as to merely bring it closer
rather than reduce its duration. This framing collapses under
the weight of scrutiny.
To start, toward has other definitions that are far more
compatible with the rest of the statutory language. As
Gonzalez identifies, toward also means “for the partial
payment of,” Toward, Webster’s Third New International
Dictionary of the English Language 2417 (2002), or “[i]n
contribution to,” Toward, Oxford English Dictionary,
https://doi.org/10.1093/OED/4426685120 (last visited July
24, 2025). This definition fits snugly and requires no
cajoling to offer meaning to the rest of the language.
“A word is known by the company it keeps (the doctrine
of noscitur a sociis),” Gustafson v. Alloyd Co., 513 U.S. 561,
575 (1995), therefore we must round out the rest of the
relevant definitions. A credit is a clear reference to “the
12 GONZALEZ V. HERRERA
balance in a person’s favor in an account,” or “an amount or
sum placed at a person’s disposal by a bank.” Credit,
Webster’s Third New International Dictionary of the English
Language 532–33 (2002). To earn is “to receive as equitable
return for work done or services rendered.” Earn, Webster’s
Third New International Dictionary of the English Language
714 (2002). As a noun, time is “a period during which
something (as an action, process, or condition) exists or
continues” or “a measured or measurable duration.” Time,
Webster’s Third New International Dictionary of the English
Language 2394–95 (2002). And as an adjective, it is simply
“of or relating to time.” Id. Finally, when something is
applied, it is “put to use especially for some practical
purpose,” “br[ought] into action,” or “l[aid] or spread on.”
Apply, Webster’s Third New International Dictionary of the
English Language 105 (2002). 4
Equipped with these definitions, the phrase “[t]ime
credits . . . shall be applied toward time in prerelease custody
or supervised release” produces three very clear ideas. 18
U.S.C. § 3632(d)(4)(C). First, earned time credits are an
amount placed at a prisoner’s disposal—a store of value
(measured in days) that incarcerated individuals receive as a
return for their participation in qualified programs. This
notion fits smoothly with the definition of toward as “for the
4
“[T]he title of a statute and the heading of a section are tools available
for the resolution of a doubt about the meaning of a statute.” Dubin v.
United States, 599 U.S. 110, 120–21 (2023). Section 3632(d)(4)(C) is
entitled “application of time credits toward prerelease custody or
supervised release.” “Application” is defined as “the act of applying” or
“the act of laying on or bringing into contact.” Application, Webster’s
Third New International Dictionary of the English Language 105 (2002).
Therefore, the statute must concern “an act of laying” time credits on
prerelease custody or supervised release.
GONZALEZ V. HERRERA 13
partial payment of”—invoking the familiar idea of working
to increase a bank account balance, which can then be
applied toward a car loan, mortgage, or other debt
obligation. Second, the statute specifically says that earned
time credits shall be applied toward “time in prerelease
custody or supervised release.” 18 U.S.C. § 3632(d)(4)(C)
(emphasis added). Time in supervised release is the “period
during which [supervised release] exists or continues.” It is
elegantly consistent, then, to apply earned time credits “for
the partial payment of” that “measurable duration.” Finally,
and most obviously, the credits are time credits that shall be
applied toward time. Not only does the statute indicate that
earned time credits store value, but it also identifies a
commodity for which they can be redeemed: time. 5 With
this context in mind, we are confident that Congress meant
to say “for the partial payment of” when it used the word
toward.
Returning to the Government’s chosen definition, if we
were to assume that toward meant “in the direction of,” the
statute’s language would become gobbledygook: “Time
credits shall be applied [in the direction of] time in prerelease
custody or supervised release.” 18 U.S.C. § 3632(d)(4)(C).
How does one apply credits “in the direction of” time—are
we meant to wave them towards the future? The
Government advocates for applying time credits to reduce
the time preceding supervised release. But § 3632(d)(4)(C)
does not mention the period of time preceding supervised
release, it identifies only “time in prerelease custody or
5
The parties do not dispute, and we agree, that when the statute refers to
“time in prerelease custody and supervised release,” it means “time in
prerelease custody” as well as “time in supervised release.” 18 U.S.C.
§ 3632(d)(4)(C).
14 GONZALEZ V. HERRERA
supervised release.” Id. (emphasis added). All the excess
conceptual baggage the Government injects into the
language—“accelerat[ing] the beginning of” supervised
release, or “bringing the defendant closer to his time in
supervised release”—is simply not there.
Moreover, the dispute over the meaning of the
preposition toward fails to take into consideration the
meaning of the transitive verb—applied. Whatever
definition we give to the preposition must fit with the verb;
prepositions give verbs direction. Therefore, drawing on the
dictionary definitions discussed above, earned time credits
must be “put to use” for, “brought into action” for, or “laid
or spread on” time in supervised release. Apply, Webster’s
Third New International Dictionary of the English Language
105 (2002). The language Congress used in § 3632(d)(4)(C)
demands that time credits must be applied to time in
supervised release somehow. All that toward can do is tell
us how they get there or what they do when they arrive. The
language is quite simple: They are applied “for the partial
payment of” time in supervised release.
Therefore, heeding § 3632(d)(4)(C)’s plain language, we
conclude that earned time credits shall be applied to reduce
the length of a supervised release term. This is not the first
time we have explained this simple notion. In 2019, we
observed that “under the [FSA’s] new ‘risk and needs
assessment system,’ receiving earned time credit can
potentially shorten prerelease custody or supervised
release.” Bottinelli, 929 F.3d at 1200 (quoting 132 Stat.
5198). Although we conclude now, as we implied in dicta
then, that the statutory language is unambiguous, some
GONZALEZ V. HERRERA 15
courts have disagreed. 6 Out of respect for the split in
authority, we shall apply the relevant interpretive tools
toward the statute’s language to better understand its
meaning.
B.
The parties each argue that the canons on interpretation
support their position. We find no need to exhaust the
interpretive playbook. The most relevant canons for this
dispute concern understanding the statute’s language (1) in
light of what Congress chose not to include, (2) in statutory
context, and (3) considering the law’s purpose. 7
1.
Applying these conventional principles, we must assume
“that Congress acts intentionally when it omits language
included elsewhere.” Dep’t of Homeland Sec. v. MacLean,
574 U.S. 383, 392 (2015). In 18 U.S.C. § 3624(b)(1),
6
The Fourth Circuit has found that “[u]nder the FSA, the time credits
can be applied toward earlier placement in pre-release custody or
supervised release.” Valladares v. Ray, 130 F.4th 74, 79 (4th Cir. 2025).
The Third Circuit has seemed to suggest that credits leftover after
advancing a release date by 12 months would remain unused. Malik v.
Warden, 23-2281, 2024 WL 3649570, at *2 (3d Cir. Aug. 5, 2024) (per
curiam). The Eleventh Circuit held that “Congress meant that the time
credits are to be used to reduce incarceration time so as to accelerate the
beginning of prerelease custody or supervised release.” Guerriero, 2024
WL 2017730, at *2; see also Stinson v. Martinez, 24-30793, 2025 WL
2017872, at *1 (5th Cir. July 18, 2025) (per curiam) (“The FSA further
provides that [earned time credits] may only be applied towards an early
start of supervised release or early transfer to pre-release custody.”).
7
Beyond these, Gonzalez invokes the rule of lenity, the Government
urges deference to BOP regulations, and both claim that legislative
history is on their side. We have considered each of these arguments and
summarily conclude they are not persuasive or necessary for disposition.
16 GONZALEZ V. HERRERA
another law creating time credits, Congress specifically
identified that “a prisoner who is serving a term of
imprisonment of more than 1 year other than a term of
imprisonment for the duration of the prisoner’s life[] may
receive credit toward the service of the prisoner’s sentence.”
(emphasis added). There, Congress intended for time credits
to reduce only custodial time, and it effectuated that goal
with clear language. By contrast, in § 3632(d)(4)(C),
Congress chose to say that the time credits “shall be applied
toward time in prerelease custody or supervised release,”
rather than “shall be applied toward the service of the
prisoner’s sentence.”
Congress knows how to write a law creating time credits
that only apply to custodial time; it did so with § 3624(b)(1).
With § 3632(d)(4)(C), Congress’s choice of words
necessarily indicates that earned time credits do more.
MacLean, 574 U.S. at 391–92; see also Jama v. ICE, 543
U.S. 335, 341 (2005) (“We do not lightly assume that
Congress has omitted from its adopted text requirements that
it nonetheless intends to apply, and our reluctance is even
greater when Congress has shown elsewhere in the same
statute that it knows how to make such a requirement
manifest.”). The Government’s position effectively asks us
to invent language not written in the statute and twist
Congress’s words to limit earned time credits’ use to
custodial time. We decline to do so and instead heed
Congress’s inclusion of other uses for earned time credits
and its omission of further limiting language.
2.
We turn to discuss the three different statutory contexts
surrounding § 3632(d)(4)(C): the whole of the
subsubsubsection; language found elsewhere in the code;
GONZALEZ V. HERRERA 17
and the statutory framework surrounding sentencing and
imprisonment. Each context further supports our conclusion
as to the statute’s meaning.
i.
Many who conclude that § 3632’s earned time credits
may not be applied to reduce a term of supervised release
have argued that § 3632(d)(4)(C)’s second sentence cabins
the meaning of the first:
Time credits earned under this paragraph by
prisoners who successfully participate in
recidivism reduction programs or productive
activities shall be applied toward time in
prerelease custody or supervised release. The
[BOP Director] shall transfer eligible
prisoners, as determined under section
3624(g),[ 8] into prerelease custody or
supervised release.
18 U.S.C. § 3632(d)(4)(C) (emphasis added). The
Government argues that because the second sentence directs
the BOP to transfer prisoners into prerelease custody or
supervised release, the first sentence is meant to authorize
use of earned time credits only for those purposes. See also
Guerriero, 2024 WL 2017730, at *2.
The starkest issue with the Government’s position is that
it renders the second sentence redundant of the first, and we
must “avoid a reading which renders some words altogether
8
Section 3624(g) explains a number of things, including who is an
“eligible prisoner,” the qualifying types of prerelease custody, and when
the BOP may release a prisoner to supervised release based on earned
time credits (no more than 12 months early). 18 U.S.C. § 3624(g)(3).
18 GONZALEZ V. HERRERA
redundant.” Gustafson, 513 U.S. at 574. Under the
Government’s reading, § 3632(d)(4)(C) says that (1) earned
time credits shall be applied to accelerate prerelease custody
or supervised release and (2) BOP shall apply earned-time
credits to accelerate prerelease custody or supervised
release. This forced redundancy is unnecessary and difficult
to comprehend.
On the contrary, § 3632(d)(4)(C) clearly does two
distinct things, each concerning the “[a]pplication of time
credits toward prerelease custody or supervised release.” Id.
§ 3632(d)(4)(C) (title). First, it declares that earned time
credits shall reduce time in prerelease custody or supervised
release, separate and apart from imprisonment. Second,
§ 3632(d)(4)(C) directs the BOP to put the prisoner on
prerelease custody or place him on supervised release
(cashing in earned time credits to do so) when a prisoner
becomes “eligible.” See 18 U.S.C. §§ 3624(g),
3632(d)(4)(C).
The fact that Congress chose not to name who will do the
“applying” in the first sentence, but did so for the second, is
another clue. The second sentence identifies the BOP
Director because the BOP Director is the officer in charge of
placing prisoners on prerelease custody and releasing them.
See 18 U.S.C. § 3624(a), (c)(1). The first sentence does not
mention the BOP because the BOP has no power to reduce a
supervised release term. In other words, the BOP could not
“apply” earned time credits toward time in supervised
release even if Congress commanded it to do so (at least not
without substantial editing to how sentences work). Id.
§ 3624(a). But the BOP can, and indeed must, transfer
eligible prisoners into prerelease custody or supervised
release based on the application of their earned time credits.
Id. § 3632(d)(4)(C).
GONZALEZ V. HERRERA 19
Accordingly, if Congress was speaking only to the BOP
when it declared that time credits “shall be applied toward
time in prelease custody or supervised release,” it could
have—and we think would have—said so. Id. Instead,
§ 3632(d)(4)(C) clearly tells us (1) what the time credits can
do, and (2) that the BOP needs to apply time credits to move
people into prerelease custody and supervised release. Such
a reading avoids redundancy and is consistent with a plain
reading of the statute’s language.
ii.
Beyond the subsubsubsection at issue, we must also
interpret the FSA to be consistent with itself, as well as with
preexisting sections of the statute. Miranda v. Anchondo,
684 F.3d 844, 849 (9th Cir. 2012) (“[U]nder the doctrine
of in pari materia, words in different sections of the same
statute should be construed similarly.” (citing Erlenbaugh v.
United States, 409 U.S. 239, 243–44 (1972))). The FSA and
its neighboring statutes are replete with comparable
language that cements our understanding.
When the FSA added Subchapter D to Title 18, chapter
229, it also amended § 3624(b). 132 Stat. 5210. Section
3624(b)(1) now reads:
[A] prisoner who is serving a term of
imprisonment of more than 1 year other than
a term of imprisonment for the duration of the
prisoner’s life, may receive credit toward the
service of the prisoner’s sentence of up to 54
days for each year of the prisoner’s sentence
imposed by the court, subject to
determination by the Bureau of Prisons that,
during that year, the prisoner has displayed
20 GONZALEZ V. HERRERA
exemplary compliance with institutional
disciplinary regulations. (emphasis added).
As briefly mentioned above, § 3624(b)(1) creates a system
of “good time credits” where the BOP may shorten a
prisoner’s term of imprisonment for good behavior while in
prison. See Bottinelli, 929 F.3d at 1197–98.
In both § 3632(d)(4)(C) and § 3624(b)(1), Congress used
the word “toward” to describe how to use time credits. Any
attempt to shoehorn the Government’s proffered definition
of “toward” into § 3624(b)(1) renders the statute
incomprehensible: “a prisoner . . . may receive credit [on a
course leading to] the service of the prisoner’s sentence of
up to 54 days . . . .” Applying the Government’s logic, the
prisoner is thereby bringing “the service of [his] sentence”
closer. To receive good time credits, the prisoner must have
already started the service of his or her sentence—how could
it be brought closer? The Government finds significant that
§ 3632(d)(4)(C) uses the phrase “applied toward,” as
opposed to § 3624(b)(1)’s “credit toward,” but fails to
elaborate on the distinction. We find no significance in it—
§ 3624(b)(1) explains what the prisoner is receiving, and
§ 3632(d)(4)(C) explains what credits are used for. The
difference in language is simply reflective of how Congress
chose to frame the statutes.
We must define “toward” consistently between the
sections as both appear in the same statute, were amended or
added under the FSA, and both concern a credit system
created for the benefit of prisoners. Further, § 3624(b)(1)’s
good time credit system and § 3632’s risk and needs
assessment system are “generally related”; it would be
improper to interpret their language differently. Bottinelli,
GONZALEZ V. HERRERA 21
929 F.3d at 1200. The obvious and consistent meaning of
both sections is that:
“a prisoner . . . may receive credit [for the
partial payment of] the service of the
prisoner’s sentence,”
and
“time credits earned . . . shall be applied [for
the partial payment of] time in prerelease
custody or supervised release.”
18 U.S.C §§ 3624(b)(1), 3632(d)(4)(C). To hold otherwise
would be to sew discord into the federal sentencing laws and
the many means by which prisoners get credit towards their
sentence. See, e.g., 18 U.S.C. §§ 3585(b) (“A defendant
shall be given credit toward the service of a term of
imprisonment for any time he has spent in official detention
prior to the date the sentence commences.”), 4105(b) (“The
transferred offender shall be given credit toward service of
the sentence for any days . . . spent in custody in connection
with the offense or acts for which the sentence was
imposed.”), 4114(e) (“The return of an offender shall be
conditioned upon the offender being given credit toward
service of the sentence for the time spent in the custody of or
under the supervision of the United States.”).
At bottom, Congress is well versed in federal sentence
crediting schemes and the language used for such laws. Our
deference to the legislature requires us to conclude that when
Congress used the word toward, it did so with the same
definition as used in preexisting laws.
22 GONZALEZ V. HERRERA
iii.
We conclude our contextual analysis by zooming out to
view how the statute fits into the statutory backdrop for
sentencing, imprisonment, and release.
When a defendant is sentenced to a term of
imprisonment by a federal district court, he or she is
committed to BOP custody until that term expires. 18 U.S.C.
§ 3621(a). The BOP maintains discretion in the
administration of imprisonment, though Congress imposes
certain duties like the provision of rehabilitative programs.
See, e.g., id. § 3621(e)–(f) (substance abuse treatment and
sex offender management). The BOP must “ensure that a
prisoner . . . spends a portion of the final months of that term
(not to exceed 12 months), under conditions that will afford
that prisoner a reasonable opportunity to adjust and prepare
for the reentry of that prisoner into the community.” Id.
§ 3624(c)(1). This phase is called “prerelease custody,” and
may involve residence at a community correctional facility
or home confinement. Id. The BOP must release prisoners
“on the date of the expiration of the prisoner’s term of
imprisonment, less any time credited toward the service of
the prisoner’s sentence” for good time as set out in
§ 3624(b). Id. § 3624(a).
A federal district court might also impose a sentence of
supervised release following imprisonment (and indeed,
most do). See 18 U.S.C. § 3583(a); United States Sentencing
Commission, Federal Offenders Sentenced to Supervised
Release 8 (July 2010) (“Over 95 percent of offenders [with
a Criminal History Category I through VI] who were
sentenced to prison received terms of supervised release.”).
For certain crimes like Gonzalez’s, Congress mandates a
sentence including a term of supervised release. 21 U.S.C.
GONZALEZ V. HERRERA 23
§ 841(b)(1)(A). When the prisoner finishes a term of
imprisonment, he or she is “released by the [BOP] to the
supervision of a probation officer who shall . . . supervise the
person released to the degree warranted by the conditions
specified by the sentencing court.” 18 U.S.C. § 3624(e).
The sentencing court imposes conditions of release and may
modify those conditions throughout the supervised release
term, extend the term up to the statutory maximum, revoke
supervised release, or end it early. See id. § 3583(d)–(e).
The FSA changed some things. To start, the FSA gave
the BOP another duty: administering the “risk and needs
assessment system” described above. Id. § 3621(h). It
waives the 12-month-before-release-date limit for persons
who have earned FSA time credits amounting to the
remainder of their term of imprisonment. Id. § 3624(g)(10).
The BOP may now apply time credits to put a prisoner on
prerelease custody for the remainder of their sentence, as
soon as he or she has earned enough time credits.
Our interpretation of § 3632(d)(4)(C) fits well into this
broader framework. The Government argues that, because
the FSA permits an earlier start to prerelease custody,
reading § 3632(d)(4)(C)’s first sentence to allow a reduction
of that time would render that provision irrelevant. Not so.
The second sentence specifically directs the BOP to transfer
prisoners into prerelease custody (or supervised release)
when they become eligible. Doing so spends earned time
credits. Then, when the prisoner has only a year of custody
remaining, the BOP shall transfer the prisoner into
supervised release, again spending earned time credits to end
prerelease custody early. Leftover earned time credits may
then be applied to reduce their supervised release term. As
a result, a prisoner may readily get the benefit of
§ 3624(g)(10)’s expansion of prerelease custody time
24 GONZALEZ V. HERRERA
alongside § 3632(d)(4)(C)’s application of earned time
credits toward supervised release.
The Government also argues that earned time credits
cannot be applied to reduce supervised release because the
FSA “contains no procedure to implement such a result.”
The FSA was enacted into a well-trod and flexible statutory
scheme for supervised release, and when “‘[f]aced with
statutory silence . . . , we presume that Congress is aware of
the legal context in which it is legislating.’” Abbey v. United
States, 112 F.4th 1141, 1153 (9th Cir. 2024) (quoting
Progressive W. Ins. Co. v. Preciado, 479 F.3d 1014, 1018
(9th Cir. 2007)). There is no basis to obviate the law’s plain
language simply because the Government would like more
detail on its operation. In sum, § 3632(d)(4)(C) fits neatly
into the federal sentencing framework, and the interpretation
we reach causes no friction with the preexisting system.
3.
We also consider a statute’s “purpose . . . to derive its
meaning.” Korotkiy, 118 F.4th at 1210; see also United
States v. Abhijit Prasad, 18 F.4th 313, 322 (9th Cir. 2021)
(“We favor an interpretation of a statute that furthers and
does not obstruct the statute’s purpose.” (citing Burns v.
Stone Forest Indus., 147 F.3d 1182, 1184 (9th Cir. 1998))).
The FSA imposed a duty on the Attorney General to
create a system of evidence-based recidivism reduction
programs, aimed at reducing recidivism. 18 U.S.C. § 3632.
Congress provided “incentives” and “rewards” for prisoners
for participating in such programs. Id. § 3632(d). Congress
directed the Attorney General to produce a report on how
effective these programs are at reducing recidivism and cost.
Id. § 3634. Section 3632(d)(4)(C)’s language should
GONZALEZ V. HERRERA 25
therefore be interpreted in a manner that serves these
purposes. Abhijit Prasad, 18 F.4th at 322.
It then follows that earned time credits should maintain
utility as an incentive for prisoners to continue
programming, thereby reducing recidivism and the cost of
managing the nation’s incarcerated and supervised
population. The Government’s interpretation allows for
earned time credits to lose their worth as an incentive. For
instance, a prisoner can participate in programming when on
prerelease custody (as Gonzalez did). See FSA Time
Credits, 87 Fed. Reg. 2705, 2712 (Jan. 19, 2022). If he has
no hope of applying earned time credits to reduce his term
of supervised release, any credits earned in excess of 365
days are worthless because they may only be applied to end
custody one year early. See id. § 3624(g)(3). But if earned
time credits could reduce time in imprisonment, in
prerelease custody, or in supervised release, their incentive
value is maximized. That is the interpretation that best
serves the purposes of the statute.
The Government disagrees, arguing that the purposes of
supervised release would be unfulfilled if unused time
credits were used to reduce a term of supervised release,
citing United States v. Johnson, 529 U.S. 53, 59 (2000). The
Supreme Court explained in Johnson that “[s]upervised
release fulfills rehabilitative ends, distinct from those served
by incarceration.” Id. The issue was whether “excess prison
time . . . offset and reduce[d] terms of supervised release.”
Id. The Supreme Court found that supervised release helps
individuals transition to community life, so the purposes of
§ 3624(e) (providing for supervision after release) would be
hindered if an unduly extended prison sentence reduced a
prisoner’s term of supervised release. Id. at 59–60.
26 GONZALEZ V. HERRERA
There is no similar friction in purpose here. Supervised
release and the FSA’s earned time credits system serve the
same end. The prisoner who earns credits is rehabilitating,
sensibly reducing his need for supervised release. The
Government’s argument to the contrary is a simple second-
guessing of Congress’s chosen path of reaching the twin
goals of rehabilitation and reduced recidivism following
release from imprisonment. We defer to Congress’s policy
choices in pursuing prisoner rehabilitation and reducing
recidivism. See Schroeder ex rel. United States, 793 F.3d
1080, 1083 (9th Cir. 2015) (rejecting an argument that
“urges us to untenably assume the role of a superlegislature
second-guessing the policy choices of the other branches of
government” (cleaned up)).
Fundamental canons of construction require that we pay
mind to what Congress did and did not say, look to the
context of the law, and to legislative purpose. Beyond the
language of the statute, which we consider fairly plain and
unambiguous, these canons each strongly indicate the same
conclusion—that the FSA’s time credits may be used to
reduce the length of time that a prisoner must spend while
on supervised release.
C.
The Government offers a parade of horribles over the
instant ruling. It insists that earned time credits may “be
used to reduce the total time on supervision for an inmate
who was deemed too risky to obtain early transfer out of
prison.” The Government fears that “defendants who served
the lengthiest terms of imprisonment . . . would be most
likely to have their terms of supervised release eliminated
altogether, leaving them without the reintegrative benefits of
supervised release.” These policy arguments are unavailing
GONZALEZ V. HERRERA 27
and in the normal case we would dismiss them without
comment, yet in light of the rhetoric and fractured authority
on the subject, we find it appropriate to explain why these
concerns are largely overblown.
There is no boogie man here. To start, prisoners
convicted of many of the most serious crimes are statutorily
excluded from earning FSA time credits. 18 U.S.C.
§ 3632(d)(4)(D) (e.g., drive-by shootings, assaulting officers
with deadly weapons, certain homicides, sexual abuse, and
dozens of others). Thus, even if these prisoners pursued
recidivism reduction programs, there is no risk of a
premature end to their terms of supervised release. Further,
to be released early, the prisoner must be found to be at a
minimum or low risk level. Id. §§ 3624(g)(1)(B),
3632(d)(4)(C). It is therefore highly inappropriate (and
illogical) to presume that the prisoners that might be let off
supervised release early present a heightened or unwarranted
level of risk, as the Government suggests.
Moreover, the Government disregards the degree of
discretion that the BOP has in executing the FSA’s risk and
needs assessment system. As soon as someone in prison
earns enough time credits to carry them through the end of
his term of imprisonment, the BOP has a choice between
prerelease custody or supervised release. Id.
§ 3632(d)(4)(C). It must choose one, but there are attendant
conditions for each, which aim to ensure only appropriate
prisoners are sent into the community. See id. § 3624(g).
Congress left that responsibility to the discretion of the BOP,
which we expect it will exercise wisely. As it pertains to a
reduction of supervised release, however, the BOP has no
role, and the Government’s sky-is-falling argument is not
persuasive. The Government simply disagrees with the
policy chosen by Congress, and “it is not [the court’s] role
28 GONZALEZ V. HERRERA
to choose what [it] think[s] is the best policy outcome and to
override the plain meaning of a statute, apparent anomalies
or not.” Guido, 859 F.3d at 1175. We decline the invitation
to legislate, and worse, to legislate against Congress’s will.
IV.
The district court misapplied § 3632(d)(4)(C).
Therefore, the district court’s order dismissing Gonzalez’s
petition for writ of habeas corpus under 28 U.S.C. § 2241 is
REVERSED and REMANDED with instructions to grant
the petition in part, direct the Government to recalculate
Gonzalez’s earned time credits, and provide the
recalculation to Gonzalez’s probation officer.
