MONT v. UNITED STATES
CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR
THE SIXTH CIRCUIT
No. 17–8995. Argued February 26, 2019—Decided June 3, 2019
Petitioner Mont was released from federal prison in 2012 and began a
5-year term of supervised release that was scheduled to end on
March 6, 2017. On June 1, 2016, he was arrested on state drug traf-
ficking charges and has been in state custody since that time. In Oc-
tober 2016, Mont pleaded guilty to state charges. He then admitted
in a filing in Federal District Court that he violated his supervised-
release conditions by virtue of the new state convictions, and he re-
quested a hearing. The District Court scheduled a hearing for No-
vember, but later rescheduled it several times to allow the state court
to first sentence Mont. On March 21, 2017, Mont was sentenced to
six years’ imprisonment, and his roughly 10 months of pretrial custo-
dy were credited as time served. On March 30, the District Court is-
sued a warrant for Mont and set a supervised-release hearing. Mont
then challenged the District Court’s jurisdiction on the ground that
his supervised release had been set to expire on March 6. The Dis-
trict Court ruled that it had jurisdiction under 18 U.S. C. §3583(i)
based on a summons it had issued in November 2016. It then re-
voked Mont’s supervised release and ordered him to serve an addi-
tional 42 months’ imprisonment to run consecutive to his state sen-
tence. The Sixth Circuit affirmed on alternative grounds, holding
that Mont’s supervised-release period was tolled under §3624(e),
which provides that a “term of supervised release does not run during
any period in which the person is imprisoned in connection with a
conviction for a . . . crime unless the imprisonment is for a period of
less than 30 consecutive days.” Because the roughly 10 months of
pretrial custody was “in connection with [Mont’s] conviction” and
therefore tolled the period of supervised release, the court concluded
that there was ample time left on Mont’s term of supervised release
2 MONT v. UNITED STATES
Syllabus
when the March warrant issued.
Held: Pretrial detention later credited as time served for a new convic-
tion is “imprison[ment] in connection with a conviction” and thus tolls
the supervised-release term under §3624(e), even if the court must
make the tolling calculation after learning whether the time will be
credited. Pp. 6–13.
(a) The text of §3624(e) compels this reading. First, dictionary def-
initions of the term “imprison,” both now and at the time Congress
created supervised release, may very well encompass pretrial deten-
tion, and Mont has not pressed any serious argument to the contrary.
Second, the phrase “in connection with a conviction” encompasses a
period of pretrial detention for which a defendant receives credit
against the sentence ultimately imposed. “In connection with” can
bear a “broad interpretation,” Merrill Lynch, Pierce, Fenner & Smith
Inc. v. Dabit, 547 U.S. 71, 85, but the outer bounds need not be de-
termined here, as pretrial incarceration is directly tied to the convic-
tion when it is credited toward the new sentence. This reading is
buttressed by the fact that Congress, like most States, instructs
courts calculating a term of imprisonment to credit pretrial detention
as time served on a subsequent conviction. See §3585(b)(1). Third,
the text undeniably requires courts to retrospectively calculate
whether a period of pretrial detention should toll a period of super-
vised release by including the 30-day minimum. The statute does not
require courts to make a tolling determination as soon as a defendant
is arrested on new charges or to continually reassess the tolling cal-
culation throughout the pretrial-detention period. Its 30-day mini-
mum-incarceration threshold contemplates the opposite. Pp. 6–8.
(b) The statutory context also supports this reading. First,
§3624(e) provides that supervised release “runs concurrently” with
“probation or supervised release or parole for another offense,” but
excludes periods of “imprison[ment]” served “in connection with a
conviction.” This juxtaposition reinforces the fact that prison time is
“not interchangeable” with supervised release, United States v. John-
son, 529 U.S. 53, 59, and furthers the statutory design of “success-
ful[ly] transition[ing]” a defendant from “prison to liberty,” Johnson
v. United States, 529 U.S. 694, 708–709. Second, it would be an ex-
ceedingly odd construction of the statute to give a defendant the
windfall of satisfying a new sentence of imprisonment and an old sen-
tence of supervised release with the same period of pretrial detention.
Supervised release is a form of punishment prescribed along with a
term of imprisonment as part of the same sentence. And Congress
denies defendants credit for time served if the detention time has al-
ready “been credited against another sentence.” §3585(b). Pp. 8–10.
(c) Mont’s argument that the statute’s present tense forbids any

backward looking tolling analysis confuses the rule with a court’s
analysis of whether that rule was satisfied. The present-tense phras-
ing does not address whether a judge must be able to make a super-
vised-release determination at any given time. Moreover, any uncer-
tainty about whether supervised release is tolled matters little from
either the court’s or the defendant’s perspective. As for the court, the
defendant need not be supervised when he is held in custody; as for
the defendant, there is nothing unfair about not knowing during pre-
trial detention whether he is also under supervised release. Pp. 10–

JASON J. MONT, PETITIONER v. UNITED STATES
ON WRIT OF CERTIORARI TO THE UNITED STATES COURT OF
APPEALS FOR THE SIXTH CIRCUIT
[June 3, 2019]
JUSTICE THOMAS delivered the opinion of the Court.
This case requires the Court to decide whether a con-
victed criminal’s period of supervised release is tolled—in
effect, paused—during his pretrial detention for a new
criminal offense. Specifically, the question is whether that
pretrial detention qualifies as “imprison[ment] in connec-
tion with a conviction for a Federal, State, or local crime.”
18 U.S. C. §3624(e). Given the text and statutory context
of §3624(e), we conclude that if the court’s later imposed
sentence credits the period of pretrial detention as time
served for the new offense, then the pretrial detention also
tolls the supervised-release period.

A
In 2004, petitioner Jason Mont began distributing co-
caine and crack cocaine in northern Ohio. After substan-
tial drug sales to a confidential informant and a search of
his home that uncovered handguns and $2,700 in cash, a
federal grand jury indicted Mont for multiple drug and
firearm offenses. He later pleaded guilty to conspiring to
possess with intent to distribute cocaine, and to possessing
a firearm and ammunition after having been convicted of a

Opinion of the Court
felony. See 18 U.S. C. §922(g)(1) (2000 ed.); 21 U.S. C.
§§841(a)(1), 846 (2000 ed.).
The District Court sentenced Mont to 120 months’ im-
prisonment, later reduced to 84 months, to be followed by
5 years of supervised release. Mont was released from
federal prison on March 6, 2012, and his supervised re-
lease was “slated to end on March 6, 2017.” 723 Fed.
Appx. 325, 326 (CA6 2018); see 18 U.S. C. §3624(e) (a
“term of supervised release commences on the day the
person is released from imprisonment”). Among other
standard conditions, Mont’s supervised release required
that he “not commit another federal, state, or local crime,”
“not illegally possess a controlled substance,” and “refrain
from any unlawful use of a controlled substance.” Judg-
ment in No. 4:05–cr–00229 (ND Ohio), Doc. 37, p. 111.
Mont did not succeed on supervised release. In March
2015, an Ohio grand jury charged him with two counts of
marijuana trafficking in a sealed indictment. Mont was
arrested and released on bond while awaiting trial for
those charges. Things only got worse from there. In
October 2015, Mont tested positive for cocaine and oxyco-
done during a routine drug test conducted as part of his
supervised release. But Mont’s probation officer did not
immediately report these violations to the District Court;
instead, the officer referred him for additional substance-
abuse counseling. Mont proceeded to test positive in five
more random drug tests over the next few months. He
also used an “ ‘unknown’ liquid to try to pass two subse-
quent drug tests.” 723 Fed. Appx., at 326. In Jan-
uary 2016, Mont’s probation officer finally reported the
supervised-release violations, including Mont’s use of drugs
and attempts to adulterate his urine samples. The violation
report also informed the District Court about the pending
state charges and the anticipated trial date of March 2016
in state court. The District Court declined to issue an
arrest warrant at that time, but it asked to “ ‘be notified of
Cite as: 587 U. S. ____ (2019) 3
Opinion of the Court
the resolution of the state charges.’ ” Ibid.; see 18 U.S. C.
§3606 (explaining that the District Court “may issue a
warrant for the arrest” of the releasee for “violation of a
condition of release”).
On June 1, 2016, approximately four years and three
months into his 5-year term of supervised release, Mont
was arrested again on new state charges of trafficking in
cocaine, and his bond was revoked on the earlier marijuana-
trafficking charges. He was incarcerated in the Ma-
honing County Jail and has remained in state custody
since that date. Mont’s probation officer filed a report
with the District Court stating that he had violated the
terms of his release based on these new state offenses.
The officer later advised the court that because Mont’s
incarceration rendered him unavailable for supervision,
the Probation Office was “toll[ing]” his federal supervision.
App. 21. The officer promised to keep the court apprised
of the pending state charges and stated that, if Mont were
convicted, the officer would ask the court to take action at
that time.
In October 2016, Mont entered into plea agreements
with state prosecutors in exchange for a predetermined
6-year sentence. The state trial court accepted Mont’s guilty
pleas on October 6, 2016, and set the cases for sentencing
in December 2016.
Three weeks later, Mont filed a written admission in the
District Court “acknowledg[ing]” that he had violated his
conditions of supervised release “by virtue of his conviction
following guilty pleas to certain felony offenses” in state
court. Record in No. 4:05–cr–00229 (ND Ohio), Doc. 92,
p. 419. Even though he had yet to be sentenced for the state
offenses, Mont sought a hearing on the supervised-release
violations at the court’s “earliest convenience.” Ibid. The
court initially scheduled a hearing for November 9, 2016,
but then, over Mont’s objection, rescheduled the hearing
several times to allow for “the conclusion of the State
4 MONT v. UNITED STATES
Opinion of the Court
sentencing.” App. 8; 723 Fed. Appx., at 327.
On March 21, 2017, Mont was sentenced in state
court to six years’ imprisonment. The judge “credited the
roughly ten months that Mont had already been incarcerated
pending a disposition as time served.” Id., at 327. The
District Court issued a warrant on March 30, 2017, and
ultimately set a supervised-release hearing for June 28,
2017.
B
Two days before that hearing, Mont challenged the
jurisdiction of the District Court based on the fact that his
supervised release had initially been set to expire on
March 6, 2017. The court concluded that it had authority
to supervise Mont, revoked his supervised release, and
ordered him to serve an additional 42 months’ imprison-
ment to run consecutive to his state sentence. The court
held that it retained jurisdiction to revoke the release
under 18 U.S. C. §3583(i), which preserves, for a “reason-
ably necessary” period of time, the court’s power to adjudi-
cate violations and revoke a term of supervised release
after the term has expired “if, before its expiration, a
warrant or summons has been issued on the basis of an
allegation of such a violation.” The court further held that
it retained authority to revoke Mont’s term of supervised
release because it gave “notice by way of a summons” on
November 1, 2016, when it originally scheduled the hear-
ing. App. 22. The court also concluded that the delay
between the guilty pleas in October 2016 and the hearing
date in June 2017 was “reasonably necessary.” Id., at 24.
The Sixth Circuit affirmed on alternative grounds. The
court could find no evidence in the record that a summons
had issued within the meaning of §3583(i). 723 Fed.
Appx., at 329, n. 5. But because Circuit precedent pro-
vided an alternative basis for affirmance, the court did not
further consider the Government’s argument that the
Cite as: 587 U. S. ____ (2019) 5
Opinion of the Court
District Court retained jurisdiction under §3583(i). In-
stead, the court held that Mont’s supervised-release period
was tolled while he was held in pretrial detention in state
custody under §3624(e), which provides:
“(e) Supervision After Release.— . . . The term of su-
pervised release commences on the day the person is
released from imprisonment and runs concurrently
with any Federal, State, or local term of probation or
supervised release or parole for another offense to
which the person is subject or becomes subject during
the term of supervised release. A term of supervised
release does not run during any period in which the
person is imprisoned in connection with a conviction
for a Federal, State, or local crime unless the impris-
onment is for a period of less than 30 consecutive
days.” (Emphasis added.)
Relying on Circuit precedent, the Sixth Circuit ex-
plained that when a defendant is convicted of the offense
for which he was held in pretrial detention for longer than
30 days and “ ‘his pretrial detention is credited as time
served toward his sentence, then the pretrial detention is
“in connection with” a conviction and tolls the period of
supervised release under §3624.’ ” Id., at 328 (quoting
United States v. Goins, 516 F.3d 416, 417 (2008)). Be-
cause Mont’s term of supervised release had been tolled
between June 2016 and March 2017, there was ample
time left on his supervised-release term when the warrant
issued on March 30, 2017.
The Courts of Appeals disagree on whether §3624(e)
tolls supervised release for periods of pretrial detention
lasting longer than 30 days when that incarceration is
later credited as time served on a conviction. Compare
United States v. Ide, 624 F.3d 666, 667 (CA4 2010)
(supervised-release period tolls); United States v. Molina-
Gazca, 571 F.3d 470, 474 (CA5 2009) (same); United

___ (2018).
II
We hold that pretrial detention later credited as time
served for a new conviction is “imprison[ment] in connec-
tion with a conviction” and thus tolls the supervised-
release term under §3624(e). This is so even if the court
must make the tolling calculation after learning whether
the time will be credited. In our view, this reading is
compelled by the text and statutory context of §3624(e).
A
Section 3624(e) provides for tolling when a person “is
imprisoned in connection with a conviction.” This phrase,
sensibly read, includes pretrial detention credited toward
another sentence for a new conviction.
First, the definition of “is imprisoned” may well include
pretrial detention. Both now and at the time Congress
created supervised release, see §212(a)(2), 98 Stat. 1999–
2000, the term “imprison” has meant “[t]o put in a prison,”
“to incarcerate,” “[t]o confine a person, or restrain his
liberty, in any way.” Black’s Law Dictionary 681 (5th ed.
1979); 5 Oxford English Dictionary 113 (1933); accord,
Black’s Law Dictionary 875 (10th ed. 2014). These defini-
tions encompass pretrial detention, and, despite the dis-
sent’s reliance on a narrower definition, post, at 5–7 (opin-
ion of SOTOMAYOR, J.), even Mont has not pressed any
serious argument to the contrary. As the Sixth Circuit
previously recognized, if imprisonment referred only to
“confinement that is the result of a penalty or sentence,
Cite as: 587 U. S. ____ (2019) 7
Opinion of the Court
then the phrase ‘in connection with a conviction’ [would]
becom[e] entirely superfluous.” Goins, supra, at 421.
Second, the phrase “in connection with a conviction”
encompasses a period of pretrial detention for which a
defendant receives credit against the sentence ultimately
imposed. The Court has often recognized that “in connec-
tion with” can bear a “broad interpretation.” Merrill
Lynch, Pierce, Fenner & Smith Inc. v. Dabit, 547 U.S. 71,
85 (2006) (interpreting “in connection with the purchase or
sale” broadly in the context of §10(b) of the Securities
Exchange Act of 1934, 15 U.S. C. §78j(b)); see, e.g., United
States v. American Union Transport, Inc., 327 U.S. 437,
443 (1946) (describing the phrase “in connection with” in
the Shipping Act, 1916, 39 Stat. 728, as “broad and gen-
eral”). The Court has also recognized that “ ‘ in connection
with’ is essentially indeterminate because connections,
like relations, stop nowhere.” Maracich v. Spears, 570
U.S. 48, 59 (2013) (quotation altered). Here, however, we
need not consider the outer bounds of the term “in connec-
tion with,” as pretrial incarceration is directly tied to the
conviction when it is credited toward the new sentence.
The judgment of the state court stated as much, crediting
the pretrial detention that Mont served while awaiting
trial and sentencing for his crimes against his ultimate
sentence for those same crimes.
This reading of “imprison[ment] in connection with a
conviction” is buttressed by the fact that Congress, like
most States, instructs courts calculating a term of impris-
onment to credit pretrial detention as time served on a
subsequent conviction. See 18 U.S. C. §3585(b)(1); Tr. of
Oral Arg. 54 (statement of the Assistant Solicitor General
representing that the same rule applies in 45 States and
the District of Columbia). Thus, it makes sense that the
phrase “imprison[ment] in connection with a conviction”
would include pretrial detention later credited as time
served, especially since both provisions were passed as
8 MONT v. UNITED STATES
Opinion of the Court
part of the Sentencing Reform Act of 1984. See §212(a)(2),
98 Stat. 2008–2009. If Congress intended a narrower
interpretation, it could have easily used narrower lan-
guage, such as “after a conviction” or “following a convic-
tion.” See e.g., Bail Reform Act of 1984, §209(d)(4), 98
Stat. 1987 (adding Federal Rule of Criminal Procedure
46(h), allowing courts to direct forfeiture of property “after
conviction of the offense charged” (emphasis added)). We
cannot override Congress’ choice to employ the more capa-
cious phrase “in connection with.”
Third, the text undeniably requires courts to retrospec-
tively calculate whether a period of pretrial detention
should toll a period of supervised release. Whereas
§3624(e) instructs courts precisely when the supervised-
release clock begins—“on the day the person is released”—
the statute does not require courts to make a tolling de-
termination as soon as a defendant is arrested on new
charges or to continually reassess the tolling calculation
throughout the period of his pretrial detention. Congress
contemplated the opposite by including a minimum-
incarceration threshold: tolling occurs “unless the impris-
onment is for a period of less than 30 consecutive days.”
§3624(e). This calculation must be made after either
release from custody or entry of judgment; there is no way
for a court to know on day 5 of a defendant’s pretrial
detention whether the period of custody will extend be-
yond 30 days. Thus, at least some uncertainty as to
whether supervised release is tolled is built into §3624(e)
by legislative design. This fact confirms that courts
should make the tolling calculation upon the defendant’s
release from custody or upon entry of judgment.
B
The statutory context also supports our reading. Super-
vised release is “a form of postconfinement monitoring”
that permits a defendant a kind of conditional liberty by
Cite as: 587 U. S. ____ (2019) 9
Opinion of the Court
allowing him to serve part of his sentence outside of
prison. Johnson v. United States, 529 U.S. 694, 697 (2000).
Recognizing that Congress provided for supervised release
to facilitate a “transition to community life,” we have
declined to offset a term of supervised release by the
amount of excess time a defendant spent in prison after
two of his convictions were declared invalid. United States
v. Johnson, 529 U.S. 53, 59–60 (2000). As we explained:
“The objectives of supervised release would be unfulfilled
if excess prison time were to offset and reduce terms of
supervised release” because “[s]upervised release has no
statutory function until confinement ends.” Id., at 59.
This understanding of supervised release informs our
reading of the tolling provision.
Consider §3624(e) itself. The sentence preceding the
one at issue here specifies that supervised release “runs
concurrently” with “probation or supervised release or
parole for another offense.” §3624(e) (emphasis added).
But the next sentence (the one at issue here) excludes
periods of “imprison[ment]” served “in connection with a
conviction.” The juxtaposition of these two sentences
reinforces the fact that prison time is “not interchange-
able” with supervised release. Id., at 59. Permitting a
period of probation or parole to count toward supervised
release but excluding a period of incarceration furthers the
statutory design of “successful[ly] transition[ing]” a de-
fendant from “prison to liberty.” Johnson, supra, at 708–
709. Allowing pretrial detention credited toward another
sentence to toll the period of supervised release is con-
sistent with that design. Cf. A. Scalia & B. Garner,
Reading Law 167 (2012) (explaining that “the whole-text
canon” requires consideration of “the entire text, in view of
its structure” and “logical relation of its many parts”).
Second, it would be an exceedingly odd construction of
the statute to give a defendant the windfall of satisfying a
new sentence of imprisonment and an old sentence of
10 MONT v. UNITED STATES
Opinion of the Court
supervised release with the same period of pretrial deten-
tion. Supervised release is a form of punishment that
Congress prescribes along with a term of imprisonment as
part of the same sentence. See generally §3583. And
Congress denies defendants credit for time served if the
detention time has already “been credited against another
sentence.” §3585(b). Yet Mont’s reading of §3624(e) would
deprive the Government of its lawfully imposed sentence
of supervised release while the defendant is serving a
separate sentence of incarceration—one often imposed by
a different sovereign. Under our view, in contrast, time in
pretrial detention constitutes supervised release only if
the charges against the defendant are dismissed or the
defendant is acquitted. This ensures that the defendant is
not faulted for conduct he might not have committed,
while otherwise giving full effect to the lawful judgment
previously imposed on the defendant.1
C
In response to these points, Mont follows the D. C.
Circuit in arguing that the present tense of the statute
(“ ‘is imprisoned’ ”) forbids any backward looking tolling
analysis. See Marsh, 829 F.3d, at 709. Mont contends
that, when a defendant is held in pretrial detention, a
court cannot say at that moment that he “is imprisoned in
connection with a conviction.” He relies on the Dictionary
Act, which provides that “[i]n determining the meaning of
any Act of Congress, unless the context indicates other-
wise[,] words used in the present tense include the future
——————
1 Our reading leaves intact a district court’s ability to preserve its
authority by issuing an arrest warrant or summons under §3583(i)
based on the conduct at issue in the new charges, irrespective of whether
the defendant is later convicted or acquitted of those offenses. But
preserving jurisdiction through §3583(i) is not a prerequisite to a court
maintaining authority under §3624(e), nor does it impact the tolling
calculation under §3624(e).
Cite as: 587 U. S. ____ (2019) 11
Opinion of the Court
as well as the present.” 1 U.S. C. §1.
Mont’s argument confuses the rule (“any period in which
the person is imprisoned in connection with a conviction”)
with a court’s analysis of whether that rule was satisfied.
Of course, the determination whether supervised release
has been tolled cannot be made at the exact moment when
the defendant is held in pretrial detention. Rather, the
court must await the outcome of those separate proceed-
ings before it will know whether “imprison[ment]” is tied
to a conviction. But the statute does not require the court
to make a contemporaneous assessment. Quite the oppo-
site: As discussed, the statute undeniably contemplates
that there will be uncertainty about the status of super-
vised release when a defendant has been held for a short
period of time and it is unclear whether the imprisonment
will exceed 30 days. There is no reason the statute would
preclude postponing calculation just because the custody
period extends beyond 30 days. Once the court makes the
calculation, it will determine whether the relevant period
ultimately qualified as a period “in which the person is
imprisoned in connection with a conviction” for 30 or more
days. In short, the present-tense phrasing of the statute
does not address whether a judge must be able to make a
supervised-release determination at any given time.
Moreover, any uncertainty about whether supervised
release is tolled matters little from either the court’s or the
defendant’s perspective. As for the court, the defendant
need not be supervised when he is held in custody, so it
does not strike us as “odd” to make a delayed determina-
tion concerning tolling. Marsh, supra, at 710. The court
need not monitor the defendant’s progress in transitioning
back into the community because the defendant is not in
the community. And if the court is concerned about losing
authority over the defendant because of an impending
conclusion to supervised release, it can simply issue a
summons or warrant under §3583(i) for alleged violations.
12 MONT v. UNITED STATES
Opinion of the Court
As for the defendant, there is nothing unfair about not
knowing during pretrial detention whether he is also
subject to court supervision. The answer to that question
cannot meaningfully influence his behavior. A defendant
in custody will be unable to comply with many ordinary
conditions of supervised release intended to reacclimate
him to society—for example, making restitution payments,
attending substance-abuse counseling, meeting curfews, or
participating in job training. The rules he can “comply”
with are generally mandated by virtue of being in prison—
for example, no new offenses or use of drugs. See
§§3563(a)–(b) (listing mandatory and discretionary condi-
tions). In this case, Mont’s supervised-release conditions
required that he “work regularly at a lawful occupation”
and “support his . . . dependants and meet other family
responsibilities.” Judgment in No. 4:05–cr–00229 (ND
Ohio), Doc. 37, at 111. Mont could not fulfill these condi-
tions while sitting in an Ohio jail, and his probation officer
correctly deemed him “unavailable for supervision.”2
App. 21.

Applying §3624(e) to Mont, the pretrial-detention period
tolled his supervised release beginning in June 2016.
Mont therefore had about nine months remaining on his
term of supervised release when the District Court re-
voked his supervised release and sentenced him to an

that circumstance, the district court may always modify the terms of
his supervision. See 18 U.S. C. §3583(e)(2). And, as the Government

be necessary to the extent that “the defendant can’t be deemed to have

§3624(e) independently tolled the supervised-release
period, it is immaterial whether the District Court could
have issued a summons or warrant under §3583(i) to
preserve its authority.

In light of the statutory text and context of §3624(e),
pretrial detention qualifies as “imprison[ment] in connec-
tion with a conviction” if a later imposed sentence credits
that detention as time served for the new offense. Such
pretrial detention tolls the supervised-release period, even
though the District Court may need to make the tolling
determination after the conviction. Accordingly, we affirm
the judgment of the Sixth Circuit.
It is so ordered.

JASON J. MONT, PETITIONER v. UNITED STATES
ON WRIT OF CERTIORARI TO THE UNITED STATES COURT OF
APPEALS FOR THE SIXTH CIRCUIT
[June 3, 2019]
JUSTICE SOTOMAYOR, with whom JUSTICE BREYER,
JUSTICE KAGAN, and JUSTICE GORSUCH join, dissenting.
A term of supervised release is tolled when an offender
“is imprisoned in connection with a conviction.” 18
U.S. C. §3624(e). The question before the Court is whether
pretrial detention later credited as time served for a new
offense has this tolling effect. The Court concludes that it
does, but it reaches that result by adopting a backward-
looking approach at odds with the statute’s language and
by reading the terms “imprisoned” and “in connection
with” in unnatural isolation. Because I cannot agree that
a person “is imprisoned in connection with a conviction”
before any conviction has occurred, I respectfully dissent.
I
A
The Sentencing Reform Act of 1984 empowers a court to
impose a term of supervised release following imprison-
ment. See 18 U.S. C. §§3583(a), (b).
The clock starts running on a supervised release term
when the offender exits the jailhouse doors. §3624(e).
During the term, offenders are bound to follow court-
imposed conditions. Some apply to all supervised release
terms, such as a requirement to refrain from committing
other crimes. §3583(d). Others apply only at a sentencing
court’s discretion, such as a condition that the offender
2 MONT v. UNITED STATES
SOTOMAYOR, J., dissenting
allow visits from a probation officer. See §3563(b)(16);
§3583(d). The probation officer, in turn, is tasked with
monitoring and seeking to improve the offender’s “conduct
and condition” and reporting to the sentencing court,
among other duties. §3603. During the supervised release
term, the court has the power to change its conditions and
to extend the term if less than the maximum term was
previously imposed. §3583(e)(2). If an offender violates
any of the conditions of release, the court can revoke su-
pervised release and require the person to serve all or part
of the supervised release term in prison, without giving
credit for time previously served on postrelease supervi-
sion. §3583(e)(3).
In the normal course, a supervised release term ends
after the term specified by the district court. But, crucially,
the term “does not run during any period in which the
person is imprisoned in connection with a conviction for a
Federal, State, or local crime unless the imprisonment is
for a period of less than 30 consecutive days.” §3624(e). In
other words, certain periods of “imprisonment” postpone
the expiration of the supervised release term.
A district court’s revocation power generally lasts only
as long as the supervised release term. If the court issues
a warrant or summons for an alleged violation before the
term expires, however, the court’s revocation power can
extend for a “reasonably necessary” period beyond the
term’s expiration. §3583(i).
B
Though the mechanics of supervised release tolling may
seem arcane, these calculations can have weighty conse-
quences. For petitioner Jason Mont, tolling enabled a
court to order an additional 31⁄2 years of federal imprison-
ment after he serves his current state sentence.
Mont was convicted in 2005 for federal drug and gun
crimes. The District Court sentenced him to prison time
Cite as: 587 U. S. ____ (2019) 3
SOTOMAYOR, J., dissenting
and to five years of supervised release. In 2012, Mont was
released from prison and his supervised release term
began. Left to run its course, the term would have ended
on March 6, 2017.1
Mont’s time on supervised release did not go well. In
January 2016, his probation officer informed the District
Court that Mont had failed two drug tests and tried to
pass two further drug tests by using an “ ‘unknown’ ” liq-
uid. 723 Fed. Appx. 325, 326 (CA6 2018). The officer
noted that Mont also had been charged with state marijuana-
trafficking offenses. Upon learning of these alleged
violations of the supervised release conditions, the District
Court could have issued a warrant for Mont’s arrest, but it
did not do so at that time.
On June 1, 2016, Mont was arrested on a new state
indictment for trafficking cocaine, and the State took him
into custody. The probation officer reported the arrest to
the District Court, but the record does not reflect any
action by the court in response. After several months in
custody, Mont pleaded guilty to certain of the state charges.
He also admitted to the District Court that he had violated
the terms of his supervised release, and he requested a
hearing. The District Court set a November hearing to
consider his alleged supervised release violation, but
continuances delayed that hearing. Months more passed
as Mont, still detained, awaited sentencing. In the mean-
time, the original end date of his federal supervised re-
lease term—March 6, 2017—came and went. On March
21, 2017, the state court sentenced Mont to six years in
prison and retroactively credited the approximately 10
months he had spent in pretrial detention toward his
sentence.

that opinion notes some immaterial discrepancies in the record. See
723 Fed. Appx. 325, 326, nn. 1–2 (2018).
4 MONT v. UNITED STATES
SOTOMAYOR, J., dissenting
At that point, Mont’s probation officer reported Mont’s
state convictions and sentences to the Federal District
Court, which—after its many earlier opportunities—
finally issued a warrant for Mont’s arrest on March 30,
2017. Mont objected, claiming that the court had no power
to issue the warrant because his supervised release term
had expired on March 6. The District Court rejected that
contention and sentenced Mont to 42 months in prison, to
run consecutively to his state sentence.2
The United States Court of Appeals for the Sixth Circuit
affirmed. In its view, the District Court had jurisdiction to
revoke Mont’s supervised release because his pretrial
detention triggered the tolling provision in §3624(e) and
thus shifted back the end date of his supervised release
term. The Sixth Circuit construed the tolling provision to
apply to Mont’s detention because his state-court indict-
ment ultimately led to a conviction and Mont subsequently
received credit for the period of detention as time served
for that conviction.
II
The majority errs by affirming the Sixth Circuit’s con-
struction of the tolling statute. Most naturally read, a
person “is imprisoned in connection with a conviction” only
while he or she serves a prison term after a conviction.
The statute does not allow for tolling when an offender is
in pretrial detention and a conviction is no more than a
possibility.
The first clue to the meaning of §3624(e) is its present-
tense construction. In normal usage, no one would say

2 The District Court held that it had jurisdiction because of a sum-
mons it issued on November 1, 2016, which would have given the court
power to sanction a supervised release violation even after the term
expired. See 18 U.S. C. §3583(i). The Sixth Circuit did not affirm on
this ground, however, because it “failed to detect any . . . evidence in
the record” of a November 2016 summons. 723 Fed. Appx., at 329, n. 5.

SOTOMAYOR, J., dissenting
that a person “is imprisoned in connection with a convic-
tion” before any conviction has occurred, because the
phrase would convey something that is not yet—and,
indeed, may never be—true: that the detention has the
requisite connection to a conviction. After all, many de-
tained individuals are never convicted because they ulti-
mately are acquitted or have their cases dismissed.3 Until
a conviction happens, it is impossible to tell whether any
given pretrial detention is “connect[ed] with” a conviction
or not.
Reading the phrase “is imprisoned” to require a real-
time assessment of the character of a conviction does not
just match the colloquial sense of the phrase; it also gives
meaning to the tense of the words Congress chose. The
Court generally “look[s] to Congress’ choice of verb tense
to ascertain a statute’s temporal reach.” Carr v. United
States, 560 U.S. 438, 448 (2010). Doing so abides by the
Dictionary Act, which provides that “words used in the
present tense include the future as well as the present”
absent contextual clues to the contrary, 1 U.S. C. §1, and
thus “the present tense generally does not include the
past,” Carr, 560 U.S., at 448. Applying this presumption
here leads to the straightforward result that the phrase “is
imprisoned” does not mean “was imprisoned.” Adhering to
the present-tense framework of the statute, then, pretrial
detention does not meet the statutory definition, no matter
what later happens.
The other language in §3624(e)—“imprisoned in connec-
tion with a conviction”—confirms this result. Had Con-

SOTOMAYOR, J., dissenting
gress wanted to toll supervised release during pretrial
confinement, it could have chosen an alternative to the
word “imprisoned” that more readily conveys that intent,
such as “confined” or “detained.” See Black’s Law Diction-
ary 362 (10th ed. 2014) (defining “confinement” as “the
quality, state, or condition of being imprisoned or re-
strained”); id., at 543 (defining “detention” as “[t]he act or
an instance of holding a person in custody; confinement or
compulsory delay”). Instead, Congress selected a word—
“imprisoned”—that is most naturally understood in con-
text to mean postconviction incarceration.
Congress regularly uses the word “imprisoned” (or
“imprisonment”) to refer to a prison term following a
conviction. The United States Code is littered with stat-
utes providing that an individual shall be “imprisoned”
following a conviction for a specific offense. See, e.g., 18
U.S. C. §§1832, 2199, 2344. Congress also classifies
crimes as felonies, misdemeanors, or infractions based on
“the maximum term of imprisonment authorized.”
§3559(a). And even in the Sentencing Reform Act itself,
which added the tolling provision at issue, Congress used
the word “imprisonment” to refer to incarceration after a
conviction. See §3582(a) (describing the factors courts
consider when imposing “a term of imprisonment”);
§3582(b) (referring to “a sentence to imprisonment”);
§3582(c)(1)(B) (discussing when courts may “modify an
imposed term of imprisonment”).
This Court also has previously equated the word “im-
prisonment” with a “prison term” or a “sentence”—phrases
that imply post-trial detention. See Tapia v. United
States, 564 U.S. 319, 327 (2011) (referring in passing to
“imprisonment” as a “prison term”); Barber v. Thomas,
560 U.S. 474, 484 (2010) (“[T]erm of imprisonment” can
refer “to the sentence that the judge imposes” or “the time
that the prisoner actually serves” of such a sentence); see
also Argersinger v. Hamlin, 407 U.S. 25, 37 (1972) (“[N]o
Cite as: 587 U. S. ____ (2019) 7
SOTOMAYOR, J., dissenting
person may be imprisoned for any offense . . . unless he
was represented by counsel at his trial”).
To be sure, dictionary definitions of the word “imprison”
sweep more broadly than just post-trial incarceration. See
ante, at 6. But the word “imprisoned” does not appear in
this statute in isolation; Congress referred to imprison-
ment “in connection with a conviction.” As part of that
phrase and given its usual meaning, the word “impris-
oned” is best read as referring to the state of an individual
serving time following a conviction.
The present tense of the statute and the phrase “impris-
oned in connection with a conviction” thus lead to the
same conclusion: Pretrial detention does not toll super-
vised release.4
III
The majority justifies a contrary interpretation of the
tolling provision only by jettisoning the present-tense view
of the statute and affording snippets of text broader mean-
ing than they merit in context.
The majority’s first error is its conclusion that courts
can take a wait-and-see approach to tolling. If a convic-
tion ultimately materializes and a court credits the of-
fender’s pretrial custody toward the resulting sentence,
the majority reasons, then the pretrial detention retroac-
tively will toll supervised release. If not, then there will
be no tolling. See ante, at 6–8. The offender’s supervised
——————
4 I note that rejecting the Sixth Circuit’s contrary interpretation of
the statute would not necessarily resolve this case in Mont’s favor. The
Government views Mont’s guilty plea as a “conviction” and thus argues
that his supervised release should, at the least, have been tolled during
the five months he was detained between his plea and sentencing. See
Brief for United States 39–44. Because the Sixth Circuit did not
directly address whether a guilty plea constitutes a “conviction,” the
appropriate course would be to remand to the Sixth Circuit to consider
this argument in the first instance. See, e.g., Cutter v. Wilkinson, 544
U.S. 709, 718, n. 7 (2005).
8 MONT v. UNITED STATES
SOTOMAYOR, J., dissenting
release status thus will be uncertain until the court calcu-
lates tolling either “upon the defendant’s release from
custody or upon entry of judgment.” Ante, at 8.
The majority’s retrospective approach cannot be squared
with the language of §3624(e). Because Congress phrased
the provision in the present tense, the statute calls for a
contemporaneous assessment of whether a person “is
imprisoned” with the requisite connection to a conviction.
The majority erroneously shifts the statute’s frame of
reference from that present-tense assessment (what is) to
a backward-looking review (what was or what has been).5
The majority’s textual argument hinges on what the
majority perceives to be an advantage of the retrospective
approach: It accounts for the fact that the statute provides
for tolling only if a period of imprisonment lasts longer
than 30 days. §3624(e). According to the majority, the 30-
day provision shows Congress’ expectation that courts look
backwards when evaluating whether tolling is appropri-
ate. If Congress anticipated such an analysis as to the
length of the detention, the majority implies, surely it
provided more generally for backward-looking review of
the relationship between the detention and any ensuing
conviction. See ante, at 8.
This argument, however, assumes a problem of the
majority’s own making. The 30-day minimum creates no
anomalies if the statute is read to toll supervised release
only during detention following a conviction. Under that
——————
5 Although Congress did not use a phrase like “was imprisoned” or
“has been imprisoned” in this provision, it did employ such formula-
tions in several other tolling provisions. See 38 U.S. C. §3103(b)(3)
(eligibility period “shall not run” during any period in which a veteran
“was . . . prevented” from accessing a rehabilitation program); §3031(b)
(time period “shall not run” during a period in which an individual “had
not met” a discharge requirement); 29 U.S. C. §1854(f ) (statute of
limitations for a federal claim “shall be tolled” for the period in which a
related state-law claim “was pending”).

SOTOMAYOR, J., dissenting
more natural reading, courts in most cases will not be left
in the dark about the length of a period of detention or its
relationship to a conviction; the conviction and sentence
of imprisonment at the time imposed will answer both
questions.6
Under the majority’s approach, however, this language
creates a dilemma. Unlike a term of imprisonment follow-
ing a conviction, the duration of pretrial confinement is
uncertain at its outset. Thus if (as the majority contends)
Congress meant to toll such periods of detention, the 30-
day limitation means that every single time a person on
supervised release enters detention, it will be unclear for
up to a month whether the supervised release term is
being tolled or not. See ante, at 8 (conceding that there
will be “no way for a court to know on day 5 of a defend-
ant’s pretrial detention whether the period of custody will
extend beyond 30 days”). If pretrial detention lasts longer
than 30 days, the uncertainty will continue until a judg-
ment of conviction is entered and credit for pretrial deten-
tion is computed.
But the difficulties inherent in predicting how long
pretrial detention will last (and whether that detention
eventually will turn out to have any connection to a con-
viction, see supra, at 4–5, and n. 3) most naturally compel
the conclusion that Congress never intended to force dis-
trict courts to grapple with them in the first place. These
uncertainties generally would not arise—and courts thus
would not need to rely on hindsight—if the Court were to
——————
6 The Government gestures to some uncertainties inherent in predict-
ing the length of imprisonment even following a conviction, such as the
presence of indeterminate sentencing schemes and the possibility that
a determinate sentence can be shortened or interrupted temporarily.
See Brief for United States 34–35 (citing 18 U.S. C. §§3621(e)(2)(B),
3622). However, these provisions in no way suggest that a court
regularly would find itself unsure whether a prisoner’s sentence will
extend past 30 days.
10 MONT v. UNITED STATES
SOTOMAYOR, J., dissenting
adopt Mont’s reading. Yet the majority instead takes as a
given that the statute tolls supervised release during
pretrial detention, and then uses the uncertainties inher-
ent in that process to justify a backward-looking analysis.
The majority’s error is compounded by the centerpiece of
its textual analysis, which relies on artificially isolating
the terms “imprisoned” and “in connection with.” The
majority says that imprisonment is a term so capacious as
to encompass pretrial detention, ante, at 6–7, and that the
phrase “in connection with” sweeps broadly enough to
include pretrial detention that is ultimately credited to a
new sentence, ante, at 7.
Whether or not these phrases independently have the
far-reaching meaning that the majority ascribes to them—
a conclusion that is by no means inevitable—the terms are
still limited by their relationship to each other and by the
present-tense framework of the statute. Individual
phrases must not be taken “ ‘in a vacuum,’ ” because doing
so overrides the “ ‘fundamental canon of statutory con-
struction that the words of a statute must be read in their
context and with a view to their place in the overall statu-
tory scheme.’ ” Home Depot U. S. A., Inc. v. Jackson, ante,
at ___ (slip op., at 5) (quoting Davis v. Michigan Dept. of
Treasury, 489 U.S. 803, 809 (1989)). As discussed, in the
context of a phrase referring to conviction, the term “im-
prisoned” most naturally means imprisonment following a
conviction. Supra, at 5–7. And seen from the point at
which a person is detained and awaiting a verdict, his
confinement is not “in connection with” a conviction that
has not happened and may never occur.
IV
The majority’s approach has the further flaw of treating
tolling as the only meaningful avenue to preserve a dis-
trict court’s revocation power when an offender is detained
pretrial. But the statute already provides a way for a
Cite as: 587 U. S. ____ (2019) 11
SOTOMAYOR, J., dissenting
court to extend its revocation power: If a court issues a
warrant or summons while the supervised release term is
running, that action triggers an extension of the court’s
revocation authority “beyond” the supervised release term
“for any period reasonably necessary for the adjudication”
of the matters that led to the warrant or summons. See
§3583(i).
In this very case, the District Court had at least three
opportunities to issue a warrant prior to the expiration of
Mont’s original supervised release term. Mont’s probation
officer notified the District Court of Mont’s potential su-
pervised release violations in January 2016, more than a
year before Mont’s supervised release was set to expire.
723 Fed. Appx. 325, 326 (CA6 2018). In June 2016, the
probation officer alerted the District Court to Mont’s
arrest. Ibid. And in October 2016, Mont filed a written
admission with the District Court that he had violated
supervised release. Id., at 326–327. The District Court
was empowered at each step of this process to issue a
warrant. Indeed, the court apparently intended to do just
that after Mont’s written admission, though the Sixth
Circuit later found that there was no evidence of such a
warrant in the record. See id., at 329, n. 5.
In sum, the delayed revocation process provides a
straightforward, and statutorily prescribed, path for dis-
trict courts to decide which charges are significant enough
to justify a warrant and thus to extend the court’s revoca-
tion power. The majority’s overly broad reading of the
tolling provision is thus unnecessary as well as a distor-
tion of the clear statutory text.
V
Lacking a strong textual basis for its backward-looking
analysis, the majority is left to rely on intuitions about
how best to fulfill the statute’s purpose.
To begin with, the majority emphasizes that supervised
12 MONT v. UNITED STATES
SOTOMAYOR, J., dissenting
release and incarceration have different aims. See ante, at
8–10. True enough. The Court has explained that super-
vised release is intended “to assist individuals in their
transition to community life,” and as a result is not “inter-
changeable” with periods of incarceration. United States
v. Johnson, 529 U.S. 53, 58–60 (2000). But the goals of
supervised release can be fulfilled to some degree even
when an offender is detained. Cf. Burns v. United States,
287 U.S. 216, 223 (1932) (noting that a probationer is still
“subject to the conditions of ” probation “even in jail”).
Offenders on supervised release may well be able to com-
ply with several mandatory conditions of supervised re-
lease while detained, such as submitting to a DNA sample
or taking drug tests. See §3583(d). And probation officers
have experience coordinating with correctional facilities in
the prerelease context. See §3624(c)(3) (providing that the
probation system “shall, to the extent practicable, offer
assistance to a prisoner during prerelease custody”).
Even if an offender’s detention does make it meaningfully
harder to fulfill the goals of supervised release, moreover,
the majority’s reading permits the same incongruities.
Under the majority’s interpretation, supervised release
continues to run for offenders who are confined pretrial for
less than 30 days and for those who are detained pretrial
but are later acquitted or released after charges are
dropped. See Tr. of Oral Arg. 34.7 At best, the majority
——————
7 Imagine two offenders on supervised release and detained pending
trial on similar charges who receive precisely the same supervision
during their detention. One ultimately is convicted and the other’s
charges are dismissed on statute of limitations grounds. Today’s
decision means that the detention time for the convicted person will not
count toward his or her supervised release term, even though the
detention of the other person—who was detained for similar conduct
and received the same monitoring and supervision—will count down
the supervised release clock. The better practice is to read the statute
on its plain terms and rely on a district court’s power to clarify any
ambiguity in its authority by issuing a warrant when an alleged super-

SOTOMAYOR, J., dissenting
offers a half-a-loaf policy rationale that cannot justify
departing from the best reading of the statute’s text.
The majority also invokes the general principle against
double-counting sentences, see, e.g., §3585(b), and objects
that Mont’s reading of the statute would give defendants a
“windfall.” Ante, at 9–10. This argument, however, fails
to recognize the distinct character of pretrial detention.
Its purpose is to ensure that an alleged offender attends
trial and is incapacitated if he or she is a danger to the
community, not to punish the offender for a conviction.
See United States v. Morales-Alejo, 193 F.3d 1102, 1105
(CA9 1999) (citing §3142(c); United States v. Salerno, 481
U.S. 739, 748 (1987)). A State or the Federal Government
may later choose to credit an equivalent period of time
toward a new sentence, but that credit does not retroac-
tively transform the character of the detention itself into
“imprison[ment] in connection with a conviction,”
§3624(e)—particularly in the context of this present-tense
statute.
In any event, the majority’s approach creates a serious
risk of unfairness. Offenders in pretrial detention will
have no notice of whether they are bound by the terms of
supervised release. This effectively compels all offenders
to comply with the terms of their release, even though only
some will ultimately get credit for that compliance, be-
cause otherwise they risk being charged with a violation if
their supervised release term is not tolled.8 Although the
majority indicates that offenders generally will comply
with the terms of their release simply by following prison
rules, the range of supervised release conditions is too

vised release violation is sufficiently serious. See §3583(i).

ishment for a failure to comply with supervision conditions while in
detention. Ante, at 12, n. 2. Given the consequences of revocation,
however, offenders may well be unwilling to take that chance. See
supra, at 2; §3583(e)(3).

broad to guarantee complete overlap with prison direc-
tives. See, e.g., Doherty, Indeterminate Sentencing Re-
turns: The Invention of Supervised Release, 88
N. Y. U. L. Rev. 958, 1012–1013 (2013) (describing manda-
tory condition of cooperating in DNA collection and special
conditions of taking prescribed medications and undergo-
ing periodic polygraph testing). Altogether, I am not
nearly as sanguine as the majority that the uncertainty
created by the majority’s expansive tolling rule “matters
little from either the court’s or the defendant’s perspec-
tive.” Ante, at 11.
* * *
The Court errs by treating Mont’s pretrial detention as
tolling his supervised release term. Because its approach
misconstrues the operative text and fosters needless un-
certainty and unfairness, I respectfully dissent.
