PER CURIAM:



∗
  Honorable Ronald Lee Gilman, United States Circuit Judge for the Sixth Circuit, sitting by
designation.
              Case: 16-11464      Date Filed: 04/04/2017     Page: 2 of 28


      Two sentencing guidelines diverge in how they treat time spent in state

custody on relevant conduct that is accounted for in a defendant’s federal sentence,

and that makes all the difference in this case. 1 U.S. Sentencing Guidelines Manual

(“U.S.S.G.”) § 5G1.3(b) requires the district court to “adjust” a defendant’s

sentence to credit him for time served in state custody on relevant conduct covered

by his federal sentence—but only when the defendant has undischarged time

remaining on his state sentence. Meanwhile, U.S.S.G. § 5K2.23 allows a district

court to exercise discretion to “depart[]” from a guidelines sentence to reflect

credit for time served in state custody on relevant conduct covered by his federal

sentence when the related state sentence is completely discharged at the time of

federal sentencing.

      Because the guidelines contemplate an “adjustment” under Part G of

Chapter 5, when a district court exercises its discretion to reduce a defendant’s

sentence under 18 U.S.C. § 3582(c)(2) after a guideline amendment, the court must

also credit the defendant for time served on an undischarged state sentence. But

since the guidelines envision a “departure” under Part K of Chapter 5, a district

court is prohibited in § 3582(c)(2) proceedings from crediting the defendant for

time served on a discharged state sentence.

      Here, at Defendant-Appellant Jose Antonio Gonzalez-Murillo’s original

sentencing, he moved for credit under U.S.S.G. § 5G1.3(b) for thirteen months’

imprisonment he served in Mississippi custody on relevant conduct covered by his

federal sentence. Though the district court purported to credit Gonzalez-Murillo

under § 5G1.3(b) for that time against his federal sentence, it referred to what it did

as a “departure.” So when Gonzalez-Murillo sought a reduced sentence under 18

U.S.C. § 3582(c)(2) following a guideline amendment, the district court granted his

motion and sentenced him to the low end of the amended guidelines range, but it

determined that it lacked the authority to adjust his sentence to reflect credit for

time served in Mississippi custody on relevant conduct.

      We have independently reviewed the record, and it is not clear to us

whether, at the time of Gonzalez-Murillo’s original sentencing, Gonzalez-

Murillo’s state sentence of imprisonment was entirely discharged or whether,

instead, Gonzalez-Murillo had additional state time remaining to be completed.

Since the answer to that question drives the answer to whether, in Gonzalez-

Murillo’s § 3582(c)(2) proceeding, the district court was required to credit or

prohibited from crediting Gonzalez-Murillo’s Mississippi time, we remand this

case to the district court to resolve that question and, if appropriate, modify

Gonzalez-Murillo’s reduced sentence accordingly.

                                        I.

A. The Offense Conduct

      The United States began investigating Jose Antonio Gonzalez-Murillo for

drug-trafficking activities in 2008. On April 13, 2010, while Gonzalez-Murillo

was under federal investigation in Florida, local law-enforcement officers stopped

him as he rode through Richland, Mississippi, on his way from California to

Florida. In the car, officers found more than 4.6 kilograms of methamphetamine.

      Based on this discovery, Mississippi charged Gonzalez-Murillo with

possession of a controlled substance, and he remained in the custody of Mississippi

authorities pending resolution of those charges. He pled guilty on April 4, 2011,

and, based on the presentence report (“PSR”) in the federal case before us now,

was purportedly sentenced to ten years’ imprisonment, with six years suspended.

      In the meantime, on December 2, 2010, in the Middle District of Florida, the

United States obtained an indictment against Gonzalez-Murillo, stemming in part

from his arrest in Mississippi. As relevant here, the indictment charged conspiracy

to possess with intent to distribute methamphetamine.

      On April 13, 2011, for the purposes of obtaining Gonzalez-Murillo’s

presence at his initial appearance on the federal charge, the United States filed a

petition in the Middle District of Florida for a writ of habeas corpus ad

prosequendum directing the United States Marshal to take custody of Gonzalez-


                                        4
               Case: 16-11464        Date Filed: 04/04/2017      Page: 5 of 28


Murillo, who was then confined in the Rankin County Jail in Brandon, Mississippi,

into federal custody from the state of Mississippi. The writ was issued on April 14,

2011. In its summary of disposition of the Mississippi conviction, the PSR

indicates that Gonzalez-Murillo was “released to United States Marshals Service”

on April 19, 2011.

       Notwithstanding the earlier issuance of a writ, however, the Middle District

of Florida court docket indicates that Gonzalez-Murillo was arrested in the

Southern District of Mississippi on April 21, 2011. Gonzalez-Murillo made his

initial appearance on the federal charges before a Southern District of Mississippi

magistrate judge, pursuant to Fed. R. Crim. P. 5(c)(2). At this proceeding, counsel

for the government moved that Gonzalez-Murillo be detained. After Gonzalez-

Murillo waived his right to a detention hearing, the magistrate judge remanded the

defendant to the Marshal to await transfer to the Middle District of Florida. 2

       On May 11, 2011, Gonzalez-Murillo was arraigned in the Middle District of

Florida on the federal indictment. At this arraignment, the magistrate judge stated

that it appeared that Gonzalez-Murillo was potentially eligible for bail, based on an

April 19, 2011, federal Pretrial Services report indicating that Gonzalez-Murillo

had been released from his Mississippi sentence. The Assistant United States

Attorney confirmed his understanding that the Mississippi sentences had

       2
          Of course, were Gonzalez-Murillo being writted into federal custody while still serving
a state sentence, he would not have been eligible for bail.
                                               5
               Case: 16-11464     Date Filed: 04/04/2017     Page: 6 of 28


“ultimately resulted in time served” and argued that Gonzalez-Murillo should be

detained. Counsel for Gonzalez-Murillo indicated his belief that the court could

set reasonable conditions of release but stated that he would make any argument

for release by a later motion.

       Ultimately, Gonzalez-Murillo entered a guilty plea to the conspiracy count.

In his plea agreement, Gonzalez-Murillo admitted, as part of the factual basis for

his guilty plea, that he was “in the process of transporting approximately 12

pounds of methamphetamine” on April 13, 2010, when he was arrested in

Mississippi.

B. Gonzalez-Murillo’s 2011 Sentencing

      At Gonzalez-Murillo’s federal sentencing, the district court used the

Sentencing Guidelines Manual in effect as of November 1, 2011, to determine an

offense level of 31 and an advisory guidelines range of 108 to 135 months’

imprisonment.      In calculating that range, the court held Gonzalez-Murillo

responsible for offense conduct involving at least five, but less than fifteen,

kilograms of methamphetamine, corresponding to a base offense level of 36 at that

time. 3 As part of this determination, the district court included the Mississippi

events as relevant conduct under U.S.S.G. § 1B1.3.



      3
          To arrive at an offense level of 31, the district court subtracted two points for
application of the safety valve (U.S.S.G. § 5C1.2) and three points for acceptance of
                                            6
               Case: 16-11464      Date Filed: 04/04/2017     Page: 7 of 28


       During the sentencing, it became clear that the district court thought that a

total sentence at the low end of the guidelines range would be appropriate to

punish Gonzalez-Murillo for all of his relevant conduct, including the Mississippi

events. The government agreed.

       Gonzalez-Murillo noted that he had served roughly thirteen months in state

custody for the Mississippi events and sought credit under U.S.S.G. § 5G1.3(b)(1)

for that state custody on his federal sentence. Though the government did not

object, it recommended (without referencing U.S.S.G. § 5K2.23) that the district

court impose the credit in the form of a departure or a variance to be sure that

Gonzalez-Murillo received his credit. The district court agreed that Gonzalez-

Murillo was entitled to credit for his time in Mississippi custody because that time

was for relevant offense conduct. Describing the government’s suggestion as the

“safest thing,” the district court decided to grant the thirteen-month credit by

calling it a “departure.”

       So the district court subtracted thirteen months from the low end of the

guideline range (108-135) to arrive at a sentence of 95 months’ imprisonment. In

pronouncing the sentence, the district court explained that it had “sentenced

[Gonzalez-Murillo] at the low end of the advisory guideline range after [it had]




responsibility (U.S.S.G. § 3E1.1(a) and (b)). The district court also determined a criminal-
history category of I.
                                             7
               Case: 16-11464        Date Filed: 04/04/2017      Page: 8 of 28


departed.”    It further noted that it had “sentence[d] [Gonzalez-Murillo] to 95

months . . . based on [U.S.S.G. §] 5G1.3(b).”

       In the Statement of Reasons for Gonzalez-Murillo’s sentence, the district

court described itself as having imposed a “departure pursuant to U.S.S.G. [§]

5G1.3(b)(1), and adjusted the sentence for the time already served in [Mississippi],

that is relevant conduct and will not be credited to the federal sentence by the

Bureau of Prisons.”

       At one point, the district court noted that Gonzalez-Murillo had been

sentenced to ten years’ imprisonment in the Mississippi case. 4 At no time during

the sentencing hearing, however, did the parties indicate that Gonzalez-Murillo had

any time remaining to be served on that earlier sentence. For example, defense

counsel never requested that the federal sentence be made to run concurrently with

the state sentence, and the court indicated that Gonzalez-Murillo would remain in

the Marshal’s custody pending designation of a federal facility.

C. The Motion for Sentence Reduction

       In February 2016, Gonzalez-Murillo filed a motion for sentence reduction

under 18 U.S.C. § 3582(c)(2). In support of his application, Gonzalez-Murillo

argued that Amendment 782 to the Guidelines, made retroactively applicable

       4
            As noted, the PSR similarly reflects that Mississippi sentenced Gonzalez-Murillo to
ten years’ imprisonment, including a six-year suspended term of imprisonment. And it does not
state that the sentence was modified to time served, but does state that Gonzalez-Murillo was
released to the Marshal’s service on April 19, 2011.
                                               8
               Case: 16-11464   Date Filed: 04/04/2017    Page: 9 of 28


through Amendment 788, reduced to 34 the offense level associated with the drug

quantity for which he was held responsible.         As a result, Gonzalez-Murillo

contended, the amendments had the effect of decreasing his guidelines range to 87

to 108 months’ imprisonment, making him eligible for a reduction of his sentence.

As Gonzalez-Murillo viewed things, the district court could choose to reduce his

sentence as low as 74 months’ imprisonment, since the low end of the guidelines

range was 87 months, and the district court had previously found that, under

U.S.S.G. § 5G1.3(b)(1), he was entitled to 13 months’ credit for time served in

Mississippi.

      Though the government did not oppose Gonzalez-Murillo’s request to be

resentenced at the low end of the amended guidelines range—87 months’

imprisonment—it argued that the district court lacked the power to grant any

further reduction.   In particular, the government described the thirteen-month

credit that the district court had applied at the original sentencing as a “departure”

under § 5G1.3 and argued that since, in its view, § 5G1.3 authorizes departures

only, a district court may not reapply a sentencing credit on resentencing under §

3582(c)(2).




                                          9
              Case: 16-11464      Date Filed: 04/04/2017     Page: 10 of 28


       The district court agreed with the government. 5            It reduced Gonzalez-

Murillo’s sentence to 87 months. But it concluded that it was not authorized to

impose a sentence below 87 months.                 Like the United States, the court

characterized itself as, at the original sentencing, having credited Gonzalez-Murillo

under § 5G1.3(b)(1) for the thirteen months in Mississippi. Yet the district court

described what it had done as a “departure.” And since a district court may not

apply a departure, other than one based on substantial assistance, in § 3582(c)(2)

reduced-sentencing proceedings, the district court did not credit Gonzalez-Murillo

for the thirteen months in Mississippi. Gonzalez-Murillo now appeals.

                                            II.

       In considering on appeal a proceeding to modify a sentence under 18 U.S.C.

§ 3582(c)(2), we review de novo the district court’s legal conclusions regarding the

scope of its authority under the Sentencing Guidelines. See United States v. White,

305 F.3d 1264, 1267 (11th Cir. 2002).

                                            III.

       To determine whether Gonzalez-Murillo was entitled to an adjustment for

his Mississippi custody to his reduced sentence imposed under § 3582(c)(2), we

must begin with the statutory language. Section 3582(c)(2) provides, in relevant

part, that when the Sentencing Commission retroactively lowers a sentencing range

       5
         Because the district court ruled on Gonzalez-Murillo’s § 3582(c)(2) motion in March
2016, the 2015 version of the U.S. Sentencing Guidelines Manual governed.
                                            10
             Case: 16-11464    Date Filed: 04/04/2017   Page: 11 of 28


applicable to a prisoner, “the court may reduce the term of imprisonment, after

considering the factors set forth in section 3553(a) to the extent that they are

applicable, if such a reduction is consistent with applicable policy statements

issued by the Sentencing Commission.” 18 U.S.C. § 3582(c)(2).

      The Supreme Court has explained that § 3582(c)(2) sets forth a two-step

process for determining whether a sentence modification should be granted. See

Dillon v. United States, 560 U.S. 817, 826-27 (2010). First, a district court must

evaluate whether reducing the sentence “‘is consistent with applicable policy

statements issued by the Sentencing Commission’—namely, § 1B1.10.” Id. at 826.

This step determines the prisoner’s eligibility for a reduced sentence under §

3582(c)(2). If a prisoner is eligible, the district court engages in the second step:

exercising its discretion to decide whether, in consideration of the § 3553(a)

factors, to reduce the sentence and, if so, by how much within the authorized

range. See id. at 827.

      Beginning with the first step, we turn to U.S.S.G. § 1B1.10 to ascertain

whether Gonzalez-Murillo was eligible for a reduced sentence. Section 1B1.10,

titled “Reduction in Term of Imprisonment as a Result of Amended Guideline

Range (Policy Statement),” generally permits a district court to reduce a prisoner’s

sentence when he was sentenced under a sentencing range that the Sentencing

Commission later retroactively lowers. See U.S.S.G. § 1B1.10; United States v.


                                         11
             Case: 16-11464    Date Filed: 04/04/2017     Page: 12 of 28


Frazier, 823 F.3d 1329, 1332 (11th Cir. 2016).           To determine a prisoner’s

eligibility for a reduced sentence, § 1B1.10(b) sets forth the following relevant

procedure:

             (1)   In General.—. . . [T]he court shall determine the
                   amended guideline range that would have been
                   applicable to the defendant if the amendment(s) to
                   the guidelines . . . had been in effect at the time the
                   defendant was sentenced.           In making such
                   determination, the court shall substitute only the
                   amendments . . . for the corresponding guideline
                   provisions that were applied when the defendant
                   was sentenced and shall leave all other guideline
                   application decisions unaffected.

             (2)   Limitation and       Prohibition     on   Extent    of
                   Reduction.—

                   (A)    Limitation.—Except [where a prisoner
                          originally received a term of imprisonment
                          beneath the low end of the guidelines,
                          based on his substantial assistance], the
                          court shall not reduce the defendant’s term
                          of imprisonment under 18 U.S.C. §
                          3582(c)(2) and this policy statement to a
                          term that is less than the minimum of the
                          amended guideline range determined under
                          subdivision (1) of this subsection.

U.S.S.G. § 1B1.10(b).

      Section 1B1.10(b)(2) clarifies that, except for original sentences reduced

beneath the bottom of the guidelines range as a result of a departure for substantial

assistance, “the court shall not reduce the defendant’s term of imprisonment under

18 U.S.C. § 3582(c)(2) and [§ 1B1.10] to a term that is less than the minimum of
                                         12
               Case: 16-11464       Date Filed: 04/04/2017      Page: 13 of 28


the amended guideline range determined under subdivision (1) of this subsection.”

U.S.S.G. § 1B1.10(b)(2).

       The commentary to § 1B1.10, which we must follow, 6 provides further

guidance on how we must apply the guideline. It explains that, in referring to the

prisoner’s “applicable guideline range” under § 1B1.10(a)(1), § 1B1.10 means “the

guideline range that corresponds to the offense level and criminal history category

determined pursuant to § 1B1.1(a), which is determined before consideration of

any departure provision in the Guidelines Manual or any variance.” U.S.S.G. §

1B1.10 cmt. n.1(A).

       We have previously construed this commentary to require a court evaluating

a § 3582(c)(2) motion for reduction of sentence to apply all eight steps of U.S.S.G.

§ 1B1.1(a) in order to determine the amended guideline range under §

1B1.10(a)(1). United States v. Hippolyte, 712 F.3d 535, 540-41 (11th Cir. 2013).7

As relevant in Gonzalez-Murillo’s case, § 1B1.1(a), in turn, instructs as follows:


       6
          See Stinson v. United States, 508 U.S. 36, 38 (1993); U.S.S.G. § 1B1.7.
       7
          In Hippolyte, Hippolyte argued that a retroactive guideline amendment resulted in a
lower applicable guideline range for him, making him eligible for a sentencing reduction under §
3582(c)(2), even though the alleged resulting guideline range was lower than the mandatory
minimum term of imprisonment required by the statute under which he was convicted. We
rejected Hippolyte’s claim, noting that step eight of § 1B1.1(a) requires the court to “use . . .
Chapter Five Parts B through G to determine various sentencing requirements and options.”
Hippolyte, 712 F.3d at 541. And U.S.S.G. § 5G1.1(b) provides that “[w]here a statutorily
required minimum sentence is greater than the maximum of the applicable guideline range, the
statutorily required minimum sentence shall be the guideline sentence.” In turn, § 1B1.1(a)
“necessarily . . . require[s]” the court “to take into account [when determining the applicable
guideline sentence for purposes of § 1B1.10] the mandatory minimum sentences that may be
statutorily required.” Id.
                                               13
Case: 16-11464   Date Filed: 04/04/2017   Page: 14 of 28


(a)   The court shall determine the kinds of sentence
      and the guideline range as set forth in the
      guidelines (see 18 U.S.C. § 3553(a)(4)) by
      applying the provisions of this manual in the
      following order, except as specifically directed.

      (1)   Determine, pursuant to § 1B1.2 (Applicable
            Guidelines), the offense guideline section
            from Chapter Two (Offense Conduct)
            applicable to the offense of conviction. See
            § 1B1.2.

      (2)   Determine the base offense level and apply
            any      appropriate      specific     offense
            characteristics, cross references, and special

            to victim, role, and obstruction of justice
            from Parts A, B, and C of Chapter Three.

                         sentencing requirements and options related
                         to probation, imprisonment, supervision
                         conditions, fines, and restitution.

U.S.S.G. § 1B1.1(a). Here, the government, the district court, and Gonzalez-

Murillo all agreed that applying steps one through seven of § 1B1.1(a) results in a

guideline range of 87 to 108 months’ imprisonment. We share that view.

      But that does not complete our inquiry. Instead, Hippolyte binds us to apply

§ 1B1.1(a)(8) before we can arrive at the amended guideline range for purposes of

§ 1B1.10(a)(1). And § 1B1.10(b)(1) requires the district court on a § 3582(c)(2)

motion to “leave all other guideline application decisions unaffected.” U.S.S.G. §

1B1.10(b)(1). So if any of Parts B through G of Chapter Five applied at Gonzalez-

Murillo’s original sentencing, we must continue to apply that part or those parts in

the same way in resolving the § 3582(c)(2) motion. We therefore consider whether

Parts B through G of Chapter Five have any effect on Gonzalez-Murillo’s

applicable guideline range.

      In the § 3582(c)(2) proceeding in this case, the district court concluded that,

at Gonzalez-Murillo’s original sentencing, it had applied U.S.S.G. § 5G1.3(b)(1)—

a guideline that appears in Part G of Chapter Five. So we take a closer look at §

5G1.3(b), including both subparts (1) and (2).

      The Supreme Court has explained the purpose of § 5G1.3 as “attempt[ing] to

achieve some coordination of sentences imposed [where separate prosecutions


                                         15
             Case: 16-11464     Date Filed: 04/04/2017    Page: 16 of 28


occur based in part on the same relevant conduct] with an eye toward having such

punishments approximate the total penalty that would have been imposed had the

sentences for the different offenses been imposed at the same time.” Witte v.

United States, 515 U.S. 389, 404 (1995). By its terms, the guideline requires the

court to “adjust” a defendant’s sentence when all four conditions it sets forth are

satisfied: (1) the defendant has time spent in custody (“prior custody”) other than

for the convictions for which he is being sentenced; (2) that time served has been

for relevant conduct that is accounted for by the sentence imposed for the federal

crime of conviction under consideration at the sentencing; (3) the Bureau of

Prisons will not itself credit the time spent in prior custody; and (4) the defendant

has undischarged time remaining on his prior custody:

             If . . . a term of imprisonment resulted from another
             offense that is relevant conduct to the instant offense of
             conviction . . . , the sentence for the instant offense shall
             be imposed as follows:

             (1)   the court shall adjust the sentence for any period of
                   imprisonment already served on the undischarged
                   term of imprisonment if the court determines that
                   such period of imprisonment will not be credited to
                   the federal sentence by the Bureau of Prisons; and

             (2)   the sentence for the instant offense shall be
                   imposed to run concurrently to the undischarged
                   term of imprisonment.

U.S.S.G. § 5G1.3(b)(1).



                                          16
             Case: 16-11464    Date Filed: 04/04/2017   Page: 17 of 28


      Section 5G1.3(b)’s language renders the provision mandatory; a court must

adjust a prisoner’s sentence when § 5G1.3(b)’s requirements are satisfied. See

U.S.S.G. § 5G1.3(b)(1) (stating that “the sentence for the instant offense shall be

imposed as follows: the court shall adjust the sentence . . .”) (emphasis added); see

also United States v. Knight, 562 F.3d 1314, 1329 (11th Cir. 2009) (vacating and

remanding for resentencing where the district court did not credit the prisoner for

time served in state custody on relevant conduct).

      And significantly, the adjustment that § 5G1.3(b) requires is not a departure.

“Departure” is a term of art under the Sentencing Guidelines. Other than those

departures that the guidelines expressly so designate, see, e.g., U.S.S.G. § 5K1.1

(substantial assistance); id. § 5K2.1 (death results from offense), a district court

may depart from the guidelines only when it “finds . . . an aggravating or

mitigating circumstance of a kind, or to a degree, not adequately taken into

consideration by the Sentencing Commission in formulating the guidelines that

should result in a sentence different from that described [by the guidelines].”

United States v. Booker, 543 U.S. 220, 234 (2005) (quoting 18 U.S.C. §

3553(b)(1)) (quotation marks omitted).

      Nothing in or relating to § 5G1.3(b) expressly designates the adjustment that

section requires as a “departure.”    So it can be a departure only if it is not

“adequately taken into consideration” by the guidelines. Of course, the mere


                                         17
              Case: 16-11464       Date Filed: 04/04/2017      Page: 18 of 28


existence of § 5G1.3(b) demonstrates that that is not the case. As a result, the §

5G1.3(b) adjustment cannot be a departure.

       Where § 5G1.3(b) applies, the application notes further specify how the

district court should memorialize on the criminal judgment its determination that §

5G1.3(b) applies:

              [T]he court should note on the Judgment in a Criminal
              Case Order (i) the applicable subsection (e.g., §
              5G1.3(b)); (ii) the amount of time by which the sentence
              is being adjusted; (iii) the undischarged term of
              imprisonment for which the adjustment is being given;
              and (iv) that the sentence imposed is a sentence reduction
              pursuant to § 5G1.3(b) for a period of imprisonment that
              will not be credited by the Bureau of Prisons.

U.S.S.G. § 5G1.3 cmt. n.2(C).

       If a defendant cannot show that he is entitled to receive credit under §

5G1.3(b) for prior custody, he may still be able to obtain credit under § 5K2.23 for

his time served. See U.S.S.G. § 5G1.3 cmt. n.5. 8 Though similar to § 5G1.3(b) in

many ways, § 5K2.23 differs from it in three material respects: (1) § 5K2.23

applies when the prior custody has been served on a sentence that is fully

discharged (rather than undischarged) at the time of the federal sentencing; (2) §

5K2.23 allows for a departure, not an adjustment; and (3) when the requirements of

       8
         “Downward Departure Provision.—In the case of a discharged term of imprisonment, a
downward departure is not prohibited if the defendant (A) has completed serving a term of
imprisonment; and (B) subsection (b) would have provided an adjustment had that completed
term of imprisonment been undischarged at the time of sentencing for the instant offense. See §
5K2.23 (Discharged Terms of Imprisonment).” U.S.S.G. § 5G1.3 cmt. n.5.
                                              18

§ 5K2.23 are satisfied, the guideline does not mandate that a district court credit

the prior custody; rather, the court has discretion to depart downward if it wishes to

do so. Section 5K2.23 provides, in relevant part,

              Discharged Terms of Imprisonment (Policy Statement)
              A downward departure may be appropriate if the
              defendant (1) has completed serving a term of
              imprisonment; and (2) subsection (b) of § 5G1.3 . . .
              would have provided an adjustment had that completed
              term of imprisonment been undischarged at the time of
              sentencing for the instant offense. Any such departure
              should be fashioned to achieve a reasonable punishment
              for the instant offense.

U.S.S.G. § 5K2.23.

      Of course, Part K of Chapter 5, where § 5K2.23 resides, does not fall within

Parts B through G of Chapter Five the way that § 5G1.3(b) does. As a result,

unlike with a § 5G1.3(b) adjustment—which a court must reapply under §

1B1.1(a) if it elects to reduce a defendant’s sentence under § 3582(c)(2)—a court

may not reapply a § 5K2.23 departure in determining the “applicable guideline

range” under § 1B1.1(a) when it chooses to reduce a defendant’s sentence under §

3582(c)(2).

      So when we are evaluating whether a defendant should be credited for prior

custody when a district court has chosen to exercise its discretion to reduce a

defendant’s sentence under § 3582(c)(2), we must ascertain whether § 5G1.3(b) or

§ 5K2.23 governed the court’s earlier award of credit. The key differentiating


                                         19
             Case: 16-11464    Date Filed: 04/04/2017     Page: 20 of 28


factor between the two provisions concerns the question of whether, at the time of

the defendant’s original federal sentencing, the prior sentence was completely

discharged or instead included an undischarged portion.

      In Gonzalez-Murillo’s case, the Statement of Reasons confirms that the

district court at his original sentencing appeared to believe that § 5G1.3 applied,

expressly identifying it as its basis for subtracting thirteen months from the

sentence it otherwise would have imposed on Gonzalez-Murillo. And, in fact, the

district court made findings on three of § 5G1.3’s requirements. First, the court

determined that Gonzalez-Murillo spent thirteen months in Mississippi custody on

Mississippi charges. Second, the court found that the time Gonzalez-Murillo spent

in Mississippi custody was for relevant conduct for which he was held accountable

in his sentence on federal conspiracy charges. And third, the court concluded that

the Bureau of Prisons would not credit Gonzalez-Murillo for that time.

      But neither the Judgment nor the Statement of Reasons indicates whether

Gonzalez-Murillo’s Mississippi custody was completely discharged at the time of

his federal sentencing. Meanwhile, the 2011 arraignment proceeding before the

magistrate judge in Florida suggests that it was. Adding to the mystery, the district

court at the original sentencing described the credit it purported to apply under §

5G1.3(b) as a “departure,” so it later concluded in the 2016 § 3582(c)(2)

proceeding that it lacked the authority to reapply the credit. As we have noted,


                                         20
             Case: 16-11464    Date Filed: 04/04/2017   Page: 21 of 28


though, any credit awarded under § 5G1.3(b) is an adjustment, not a departure, and

once § 5G1.3(b)’s requirements are satisfied, the district court must apply that

adjustment to any reduced sentence it chooses to impose.

      Since we cannot be certain from this record whether Gonzalez-Murillo’s

Mississippi sentence had been discharged at the time of his original sentencing in

this case or whether, instead, part of it remained undischarged, we remand this

matter to the district court to make a factual finding in that regard.        If the

Mississippi sentence was not fully discharged when Gonzalez-Murillo was

originally sentenced, the district court shall apply the thirteen-month § 5G1.3(b)

adjustment to Gonzalez-Murillo’s reduced sentence for a resulting reduced

sentence of 74 months. If, on the other hand, the Mississippi sentence was fully

discharged when Gonzalez-Murillo was originally sentenced, the district court has

no discretion to further reduce Gonzalez-Murillo’s reduced sentence below 84

months because the credit it awarded resulted from a departure under § 5K2.23,

and that type of departure may not be applied in a § 3582(c)(2) proceeding.

                                       IV.

      For the reasons we have discussed, we remand this case for further

proceedings consistent with this opinion. In doing so, we note that if Gonzalez-

Murillo’s Mississippi sentence was not fully discharged when he was originally

sentenced, thereby making § 5G1.3 applicable, it appears that Gonzalez-Murillo

may be eligible for release either immediately or in the near future. For this

reason, we direct the district court to conduct the further proceedings in this case at

the earliest possible time.

ROSENBAUM, Circuit Judge, concurring:

      Of course, we are bound to apply the law as it is written. So that is what we

do. Here, what the Sentencing Guidelines require is clear and unambiguous. I

write separately to note only that the apparent incongruity of results between §§

5G1.3 and 5K2.23 seems out of line with the purpose of § 5G1.3.

      As we have indicated, the Supreme Court has described § 5G1.3 as an

“attempt[] to achieve some coordination of sentences imposed [where separate

prosecutions occur based in part on the same relevant conduct] with an eye toward

having such punishments approximate the total penalty that would have been

imposed had the sentences for the different offenses been imposed at the same

time.” Witte, 515 U.S. at 404. Indeed, the Supreme Court has characterized

§ 5G1.3 as a “[s]ignificant safeguard[] built into the Sentencing Guidelines . . . to

protect [a] petitioner against having the length of his sentence multiplied by

duplicative consideration of the same criminal conduct.” Id. at 405.

      We have further elaborated on the important role of § 5G1.3 in “protect[ing]

a criminal defendant from duplicative prosecutions.” United States v. Bidwell, 393

F.3d 1206, 1209 (11th Cir. 2004). As we have explained, “The Double Jeopardy

Clause does not prevent different sovereigns (i.e., a state government and the

                                         23
               Case: 16-11464        Date Filed: 04/04/2017       Page: 24 of 28


federal government) from punishing a defendant for the same criminal conduct.

 But §§ 5G1.3 and 1B1.3 [explaining the meaning of “relevant conduct” in the

Guidelines] do. These sections seek ‘to provide one, uniform punishment for the

same criminal activity.’” Id. (citation omitted).

       Whether a defendant’s state sentence for relevant conduct has been fully

discharged or not at the time of his federal sentencing seems to me to have no

logical bearing on the district court’s determination of an appropriate total sentence

for all relevant conduct on which it is sentencing the defendant.

       I am aware that two circuits have found a rational basis for the difference in

treatment between defendants with discharged and undischarged sentences on

relevant conduct.1 See United States v. Dunham, 295 F.3d 605, 610-11 (6th Cir.

2002); United States v. Otto, 176 F.3d 416, 418 (8th Cir. 1999). Most respectfully,

I disagree that either circuit’s analysis survives scrutiny. 2



       1
          A third circuit denied an equal-protection challenge to 18 U.S.C. § 3584’s distinction in
treatment between discharged and undischarged sentences, but it did not offer an explanation as
to why the distinction has a rational basis, instead finding that the defendant had failed to meet
his burden to show that a rational basis was lacking. See United States v. Lucas, 745 F.3d 626,
630-31 (2d Cir. 2014).
        2
          In fairness to the Sixth and Eighth Circuits, the version of § 5G1.3(b) that they reviewed
differed from the one applicable in Gonzalez-Murillo’s case. The older version did not contain
what is now § 5G1.3(b)(1). Instead, § 5G1.3(b) then provided, “If . . . the undischarged term of
imprisonment resulted from offense(s) that have been fully taken into account in the
determination of the offense level for the instant offense, the sentence for the instant offense
shall be imposed to run concurrently to the undischarged term of imprisonment.” That provision
is effectively the equivalent of what is now § 5G1.3(b)(2). The difference in provisions might
help explain some of these circuits’ analysis. But to simplify my discussion of the reasoning that
the Eighth and Sixth Circuits provided justifying the difference in treatment between discharged
                                                24
              Case: 16-11464       Date Filed: 04/04/2017     Page: 25 of 28


       First, the Sixth Circuit has opined that the distinction between discharged

and undischarged sentences “ensures that if two defendants who are convicted of

identical state law crimes are subsequently convicted on a federal charge for the

same conduct that formed the factual basis of their state convictions, then those

two defendants will serve an equal term of imprisonment upon their federal

conviction, regardless of whether their state sentence had been fully discharged.”

Dunham, 295 F.3d at 611. In the Sixth Circuit’s view, if this distinction did not

exist and defendants were credited for time served on both discharged and

undischarged state sentences involving relevant conduct, “a defendant with a

previously discharged state sentence would serve a shorter term of imprisonment

upon his subsequent federal conviction than would a defendant with an

undischarged state sentence.” Id.

       Most respectfully, I disagree. Imagine two defendants charged by both the

state and the federal government for the same conduct, but Defendant A is arrested

on his state charges before Defendant B. Both defendants are ultimately sentenced

to the exact same term of ten months’ imprisonment for their state crimes.

Because Defendant A was arrested earlier than Defendant B, though, Defendant A

completes his sentence before being arrested for his federal crimes. Defendant B,




and undischarged sentences, I address their articulated reasons as though they offered them in
response to the current version of § 5G1.3(b).
                                             25
               Case: 16-11464       Date Filed: 04/04/2017      Page: 26 of 28


on the other hand, is writted into federal custody to face federal charges while he

still has one month left on the sentence that Defendant A has already completed.

In both cases, the district court concludes that the total appropriate sentence is two

years’ imprisonment.

       Under § 5G1.3(b), Defendant B must be sentenced to 15 months in federal

prison instead of 24 months because he must receive credit for the nine months he

has served in state prison since his state sentence is not fully discharged. And the

tenth month on the state time must run concurrently with the federal sentence

imposed.      See § 5G1.3(b)(2).         So between his state and federal sentences,

Defendant B serves a total of 24 months. Defendant A, however, is not entitled to

credit for his ten months in state custody because his state sentence has been

completely discharged at the time of his federal sentencing. Though the district

court could choose to downwardly depart under § 5K2.23, it decides not to do so.

So it imposes a federal sentence of 24 months’ imprisonment. Defendant A will

then serve a total sentence of 34 months on his relevant conduct, accounting for

both the state and federal time he will spend. 3


       3
          Gonzalez-Murillo’s case is not before us on an equal-protection challenge as it was
before the Sixth Circuit. So we do not consider and I do not suggest a view on that issue.
Instead, I discuss Dunham for the sole purpose of explaining why I do not believe that the Sixth
Circuit’s explanation for the difference in treatment between discharged and undischarged
sentences shows how the mere fact that a state sentence may have been discharged or
undischarged bears on what the total punishment for all relevant conduct should be. The
Northern District of Illinois reached a similar conclusion about Dunham’s analysis when it
considered it in the context of evaluating the distinction in 18 U.S.C. § 3584 between discharged
                                               26
               Case: 16-11464        Date Filed: 04/04/2017       Page: 27 of 28


       And if the guidelines are amended so that Defendants A and B are eligible

for reduced sentences under § 3582(c)(2), then even if, during his original

sentencing, Defendant A receives a downward departure for time served in state

custody on relevant conduct, he cannot get the benefit of that credit in the §

3582(c)(2) proceeding. But Defendant B must receive the credit.

       As for the Eighth Circuit, it reasoned that “[w]ith undischarged sentences,

there remains uncertainty as to the amount of time a defendant will actually serve.”

Otto, 176 F.3d at 418. So, according to the Eighth Circuit, “a defendant could be

paroled, placed on probation after serving some period of shock detention, given

credit off a sentence for good behavior, or have the sentence vacated.” Id. But

with a discharged sentence, “[t]here are no such contingencies.” Id.

       In my view, this analysis does not explain how or why crediting time served

on state sentences with remaining time, but not crediting fully discharged state

sentences on relevant conduct, furthers the purpose of imposing a single total




and undischarged terms of imprisonment. See United States v. Hill, 187 F. Supp. 3d 959, 968
(N.D. Ill. 2016). There, the court concluded that the distinction was an “arbitrary [one] that
violates the Fifth Amendment’s due process guarantee.” Again, though, this issue is not before
us, so I do not opine on it. I cite Hill’s determination for only the purpose of demonstrating that
the distinction between how discharged and undischarged terms of imprisonment are treated
seems inconsistent with the purpose of § 5G1.3 to effectively impose a total term of
imprisonment that accounts for both the federal and relevant state conduct.
                                                27
              Case: 16-11464     Date Filed: 04/04/2017     Page: 28 of 28


punishment for all relevant conduct.4 Rather, it seems to me that crediting all state

time already served for relevant conduct—whether the sentence is fully discharged

or not at the time of federal sentencing—and running any undischarged state time

concurrently with the federal sentence imposed is the only way to accomplish a

total sentence that accounts for all relevant conduct without being duplicative.

      In short, it is not clear to me why the mere discharged or undischarged

nature of a state sentence involving relevant conduct should affect, at either his

original sentencing or his § 3582(c)(2) proceedings, a defendant’s entitlement to

credit for his state custody. Perhaps a good reason for the distinction in treatment

between discharged and undischarged sentences exists, one that makes sense in

light of the purpose of § 5G1.3(b) as the Supreme Court has explained that

purpose. But if not, it is time to extinguish that difference in treatment.




      4
         If anything, it suggests that better reasons exist to credit discharged time than
undischarged time. But § 5G1.3(b)(2) accounts for that problem by making undischarged time
run concurrently with federal time imposed.
