CHAPTER FIVE - DETERMINING THE SENTENCING RANGE AND OPTIONS UNDER THE GUIDELINES
§5G1.3. IMPOSITION OF A SENTENCE ON A DEFENDANT SUBJECT TO AN UNDISCHARGED TERM OF IMPRISONMENT OR ANTICIPATED STATE TERM OF IMPRISONMENT

(a) If the instant offense was committed while the defendant was serving a term of imprisonment (including work release, furlough, or escape status) or after sentencing for, but before commencing service of, such term of imprisonment, the sentence for the instant offense shall be imposed to run consecutively to the undischarged term of imprisonment.

(b) If subsection (a) does not apply, and a term of imprisonment resulted from another offense that is relevant conduct to the instant offense of conviction under the provisions of subsections (a)(1), (a)(2), or (a)(3) of §1B1.3 (Relevant Conduct), 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 remainder of the undischarged term of imprisonment.

(c) If subsection (a) does not apply, and a state term of imprisonment is anticipated to result from another offense that is relevant conduct to the instant offense of conviction under the provisions of subsections (a)(1), (a)(2), or (a)(3) of §1B1.3 (Relevant Conduct), the sentence for the instant offense shall be imposed to run concurrently to the anticipated term of imprisonment.

(d) (Policy Statement) In any other case involving an undischarged term of imprisonment, the sentence for the instant offense may be imposed to run concurrently, partially concurrently, or consecutively to the prior undischarged term of imprisonment to achieve a reasonable punishment for the instant offense.

Commentary

Application Notes:

1. Consecutive Sentence - Subsection (a) Cases. Under subsection (a), the court shall impose a consecutive sentence when the instant offense was committed while the defendant was serving an undischarged term of imprisonment or after sentencing for, but before commencing service of, such term of imprisonment.

2. Application of Subsection (b).—

(A) In General.—Subsection (b) applies in cases in which all of the prior offense is relevant conduct to the instant offense under the provisions of subsection (a)(1), (a)(2), or (a)(3) of §1B1.3 (Relevant Conduct). Cases in which only part of the prior offense is relevant conduct to the instant offense are covered under subsection (d).

(B) Inapplicability of Subsection (b).—Subsection (b) does not apply in cases in which the prior offense was not relevant conduct to the instant offense under §1B1.3(a)(1), (a)(2), or (a)(3) (e.g., the prior offense is a prior conviction for which the defendant received an increase under §2L1.2 (Unlawfully Entering or Remaining in the United States), or the prior offense was a crime of violence for which the defendant received an increased base offense level under §2K2.1 (Unlawful Receipt, Possession, or Transportation of Firearms or Ammunition; Prohibited Transactions Involving Firearms or Ammunition)).

(C) Imposition of Sentence.—If subsection (b) applies, and the court adjusts the sentence for a period of time already served, the 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 the relevant case information (including docket number); 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.

(D) Example.—The following is an example in which subsection (b) applies and an adjustment to the sentence is appropriate:

The defendant is convicted of a federal offense charging the sale of 90 grams of cocaine. Under §1B1.3, the defendant is held accountable for the sale of an additional 25 grams of cocaine, an offense for which the defendant has been convicted and sentenced in state court. The defendant received a nine-month sentence of imprisonment for the state offense and has served six months on that sentence at the time of sentencing on the instant federal offense. The guideline range applicable to the defendant is 12–18 months (Chapter Two offense level of level 16 for sale of 115 grams of cocaine; 3 level reduction for acceptance of responsibility; final offense level of level 13; Criminal History Category I). The court determines that a sentence of 13 months provides the appropriate total punishment. Because the defendant has already served six months on the related state charge as of the date of sentencing on the instant federal offense, a sentence of seven months, imposed to run concurrently with the three months remaining on the defendant’s state sentence, achieves this result.

3. Application of Subsection (c).—Subsection (c) applies to cases in which the federal court anticipates that, after the federal sentence is imposed, the defendant will be sentenced in state court and serve a state sentence before being transferred to federal custody for federal imprisonment. In such a case, where the other offense is relevant conduct to the instant offense of conviction under the provisions of subsections (a)(1), (a)(2), or (a)(3) of §1B1.3 (Relevant Conduct), the sentence for the instant offense shall be imposed to run concurrently to the anticipated term of imprisonment.

4. Application of Subsection (d).—

(A) In General.—Under subsection (d), the court may impose a sentence concurrently, partially concurrently, or consecutively to the undischarged term of imprisonment. In order to achieve a reasonable incremental punishment for the instant offense and avoid unwarranted disparity, the court should consider the following:

(i) the factors set forth in 18 U.S.C. § 3584 (referencing 18 U.S.C. § 3553(a));

(ii) the type (e.g., determinate, indeterminate/parolable) and length of the prior undischarged sentence;

(iii) the time served on the undischarged sentence and the time likely to be served before release;

(iv) the fact that the prior undischarged sentence may have been imposed in state court rather than federal court, or at a different time before the same or different federal court; and

(v) any other circumstance relevant to the determination of an appropriate sentence for the instant offense.

(B) Partially Concurrent Sentence.—In some cases under subsection (d), a partially concurrent sentence may achieve most appropriately the desired result. To impose a partially concurrent sentence, the court may provide in the Judgment in a Criminal Case Order that the sentence for the instant offense shall commence on the earlier of (i) when the defendant is released from the prior undischarged sentence; or (ii) on a specified date. This order provides for a fully consecutive sentence if the defendant is released on the undischarged term of imprisonment on or before the date specified in the order, and a partially concurrent sentence if the defendant is not released on the undischarged term of imprisonment by that date.

(C) Undischarged Terms of Imprisonment Resulting from Revocations of Probation, Parole or Supervised Release.—Subsection (d) applies in cases in which the defendant was on federal or state probation, parole, or supervised release at the time of the instant offense and has had such probation, parole, or supervised release revoked. Consistent with the policy set forth in Application Note 3 and subsection (f) of §7B1.3 (Revocation of Probation), the Commission recommends that the sentence for the instant offense be imposed consecutively to the sentence imposed for the revocation.

(D) Complex Situations.—Occasionally, the court may be faced with a complex case in which a defendant may be subject to multiple undischarged terms of imprisonment that seemingly call for the application of different rules. In such a case, the court may exercise its discretion in accordance with subsection (d) to fashion a sentence of appropriate length and structure it to run in any appropriate manner to achieve a reasonable punishment for the instant offense.

(E) Imposition of Sentence.—Unlike subsection (b), subsection (d) does not address an adjustment of the sentence for the instant offense for a period of imprisonment already served on the undischarged term of imprisonment. If the court does account for an undischarged term of imprisonment under subsection (d) in imposing the sentence, the Commission recommends that the court clearly state that the sentence was imposed pursuant to 18 U.S.C. § 3553(a), rather than as a credit for time served, to avoid confusion with the Federal Bureau of Prisons’ exclusive authority provided under 18 U.S.C. § 3585(b) to grant credit for time served under certain circumstances.

The court should note on the Judgment in a Criminal Case Order (i) that the sentence was imposed pursuant to 18 U.S.C. § 3553(a); (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 the relevant case information (including docket number); and (iv) that the sentence imposed is to account for a period of imprisonment that will not be credited by the Federal Bureau of Prisons.

5. Discharged Term of Imprisonment.—This guideline does not address an adjustment of the sentence for the instant offense for a period of imprisonment already served on a discharged term of imprisonment. Nonetheless, nothing in the Guidelines Manual abrogates a court’s authority under 18 U.S.C. § 3553(a) to consider a previously completed term of imprisonment in determining an appropriate sentence where subsection (b) above would have provided an adjustment had that completed term of imprisonment been undischarged at the time of sentencing for the instant offense. 

Background: Federal courts generally “have discretion to select whether the sentences they impose will run concurrently or consecutively with respect to other sentences that they impose, or that have been imposed in other proceedings, including state proceedings.” See Setser v. United States, 566 U.S. 231, 236 (2012); 18 U.S.C. § 3584(a). Federal courts also generally have discretion to order that the sentences they impose will run concurrently with or consecutively to other state sentences that are anticipated but not yet imposed. See Setser, 566 U.S. at 236. Exercise of that discretion, however, is predicated on the court’s consideration of the factors listed in 18 U.S.C. § 3553(a), including any applicable guidelines or policy statements issued by the Sentencing Commission.
