OPINION OF THE COURT
Michael Murray appeals for the second time from a judgment in a criminal case. 1 In his first appeal, a panel of this court vacated one count of his conviction, affirmed two others, and remanded for resentencing on the affirmed counts. Murray now challenges the sentences imposed on remand. His appeal raises interesting and difficult questions concerning the contours of the so-called Sentencing Package Doctrine (the “doctrine”) under the regime of the Sentencing Guidelines. Rejecting • Murray’s several contentions, we hold that the district court had the authority to resentence Murray on the affirmed counts; that there is no constitutional barrier to the district court imposing life sentences on those counts; that the district court did not abuse its discretion by departing from the applicable guideline range; and that the extent of the departure was reasonable. We therefore affirm the judgment.
I.
Murray was convicted following a jury trial of the intentional killing of Juan Carlos Bacallo in furtherance of a Continuing Criminal Enterprise (“CCE”), in violation of 21 U.S.C. § 848(e)(1)(A); conspiracy to distribute in excess of five (5) kilograms of cocaine in violation of 21 U.S.C. §§ 846 and 841(a)(1); and distribution of and possession with the intent to distribute cocaine in violation of 21 U.S.C. § 841(a)(1). On January 19, 1996, Murray was sentenced to a term of life imprisonment for the CCE-related murder and to two concurrent ten-year sentences on the
*272
drug counts.
2
Murray timely appealed his convictions, and, in
United States v. Murray,
For the foregoing reasons, we reverse the judgment of conviction and sentence on the murder charge and remand for a new trial. We affirm the judgment of conviction as to .the drug charges and remand for resentencing, if appropriate, on those counts.
On remand, the government took the position that the district court could permissibly vacate the concurrent ten-year terms imposed on the two drug counts and resentence Murray to life imprisonment—thus obviating the need (in practical terms) for a retrial on the murder charge. Murray objected to this procedure, but the district court proceeded with the resentencing. A revised presentence report ordered by the district court advised that the guideline level for Murray’s drug offenses was 34, and that the murder of Bacallo was relevant conduct which could justify an upward departure pursuant to U.S.S.G. § 5K2.1 (Death); and § 5K2.8 (Extreme Conduct). On April 10, 1997, the district court departed upwards and resentenced Murray to two concurrent terms of life imprisonment on the drug counts and imposed a $10,000 fine.
At the resentencing, the district court gave the following reasons for its departure:
The Court believes that there is clear and convincing evidence that the defendant committed murder. The killing ■ of Juan Carlos Bacallo is relevant conduct associated with the defendant’s offense of conviction and is an integral, aggravating circumstance not covered by the offense guideline.
The most analogous guideline to this relevant conduct is United States Sentencing Guidelines § 2A1.1 and offense level 43. Further, the dangerousness of the defendant’s conduct, his intent prior to the killing and the cruel nature of the killing present the need for a consequence and a departure under the United States Sentencing Guideline 5K2.1 and section 5K2.8 for the loss of life caused by the defendant and his extreme conduct.
An upward departure of nine levels is deemed reasonable, and the sentence imposed is considered necessary after consideration of the nature and seriousness of the offense and the need to afford an adequate deterrent as required by 18 U.S.C. § 3553.
In addition, the district court entered into the record an Addendum to Statement of Reasons for the departure wherein it stated:
It is noted that because the drug convictions involved more than five kilograms of cocaine, 21 U.S.C. § 841(b)(1)(A) reflects that the Court must impose a sentence of no less than 10 years and can impose life imprisonment. While it appears that the court can not use the intentional killing in determining the defendant’s guideline calculations, it is relevant conduct and can therefore be used in support of a substantial upward depart at resentencing on the drug counts. [See also United States v. Baird,109 F.3d 856 (3d Cir.1997) ]
This appeal followed. The government informed us at oral argument that it does not intend to retry Murray on the murder charge if the resentencing on the drug counts is affirmed.
II.
Murray first contends that the district court was without authority to resentence him on the drug counts. This argument is foreclosed by this court’s mandate in
Murray I.
There the panel “affirm[ed] the
*273
judgment of conviction as to the drug charges and remand[ed] for resentencing, if appropriate, on those counts.”
Because of. the mandate, Murray’s claim that the district court lacked the authority to resentence him reduces to an attack on this court’s authority, pursuant to 28 U.S.C. § 2106 (1997), to vacate the sentences on the drug counts and remand for resentencing. This argument is derived from
United States v. Busic,
Based on this language, which gave rise to what has since been termed the sentencing package doctrine, Murray argues that resentencing is inappropriate in this ease since his drug sentences were ordered to be served concurrently to his murder sentence, and hence the sentences were not interdependent. This argument raises interesting and difficult questions regarding the breadth of the doctrine and its continued relevance in the era of Guideline sentencing. However, we need not reach these issues here. 4 Un *274 like the defendant in Busic, Murray did challenge his conviction on the drug counts. The Murray I panel’s authority to remand for resentencing on those counts thus stems directly from 28 U.S.C. § 2106, which we set forth in the margin. 5 The authority granted by § 2106 is discretionary, and while the jurisprudence of sentencing, including the *275 concepts underlying the sentencing package doctrine, serves as a guide to courts in making the determination whether remand is appropriate, the courts of appeals are not bound to apply these concepts in determining whether to remand for resentencing on counts “lawfully brought before [them] for review.” Here, the panel did not state the reasons supporting its decision to remand the drug counts for resentencing. However, even if it had, and we disagreed with those reasons, the fact is that it has done so, and we are without authority on this appeal to substitute our views for those of the Murray I panel.
III.
Turning to the legality of the life sentences imposed on remand, we find Murray’s arguments that his resentencing violates his due process rights and the prohibition against double jeopardy to be without merit.
6
Murray’s due process claim is predicated on
North Carolina v. Pearce,
IV.
Finally, Murray argues that the nine-level upward departure to a base offense level of 43 was not reasonable and should be reduced by this court.
7
We disagree. The district court properly followed the course charted in
United States v. Kikumura,
The judgment of the district court will be affirmed.
Notes
Honorable Edward R. Becker, United States Circuit Judge for the Third Circuit, assumed Chief Judge status on February 1, 1998.
. We exercise jurisdiction pursuant to 28 U.S.C. § 1291.
. Murray was also ordered to pay restitution in the amount of $2,304.00 to the murder victim's family.
. More specifically, the reversal was based upon the admission of evidence that the court determined to be inappropriate under Fed.R.Evid. 404(b) and 403, as well as evidence that contravened Fed.R.Evid. 608(b).
. The sentencing package doctrine originated as a means of justifying the resentencing of a defendant on all counts of a multicount conviction where one or more counts were reversed on direct appeal. The rationale underlying the doctrine was that
[w]hen a defendant is found guilty on a multicount indictment, there is a strong likelihood that the district court will craft a disposition in which the sentences on the various counts form part of an overall plan. When the conviction on one or more of the component counts is vacated, common sense dictates that the judge should be free to review the efficacy of what remains in light of the original plan, and to reconstruct the sentencing architecture upon remand, within applicable constitutional and statutory limits, if that appears necessary in order to ensure that the punishment still fits both crime and criminal.
United. States v. Pimienta-Redondo,
The question of interdependence is more complex under the Guidelines. As several of our sister circuits have noted, the Guidelines have eliminated much of the district court’s discretion at sentencing, thereby altering, though not necessarily eliminating, the concept of a sentencing package.
See United States v. Rodriguez,
In
Davis,
the defendant had been convicted of several drug counts and one count of using a firearm during and in relation to a drug trafficking crime in violation of 18 U.S.C. § 924(c). A conviction under § 924(c) requires, as a matter of law, the imposition of a five year sentence to be served consecutively to any other term of imprisonment associated with an underlying drug count.
See
18 U.S.C. § 924(c)(1). Moreover, under U.S.S.G. § 2D1.1(b)(1), the base offense level for crimes involving drugs must be increased by two levels if "a dangerous weapon (including a firearm) was possessed.” U.S.S.G. § 2D1.1(b)(1). The Guidelines further direct that this enhancement should not be applied when a
*274
sentence under § 924(c) is also imposed.
See
U.S.S.G. § 2K2.4, Commentary Background. Following the Supreme Court's decision in
Bailey v. United States,
We disagreed, finding "jurisdiction based on the interdependence of the counts for Guideline sentencing purposes.” Id. at 121. We explained our holding as follows:
Clearly, the § 924(c) offense and the underlying offense are interdependent and result in an aggregate sentence, not sentences which may be treated discretely. If the district court were to vacate the term associated with the § 924(c) count and not resentence on the remaining counts, Davis would not receive the two level enhancement required for the remaining counts under the Sentencing Guidelines and his sentence would not be in conformity with the law.
Id. at 121 (citations omitted).
The scenario in
Davis
provides a clear example of interdependence under the Guidelines since it is evident that the. particular guidelines themselves "contemplate[d] an interdependent relationship between the sentence for the vacated
conviction
and the sentence for the remaining convictions—a sentence package____”
Rodriguez,
The government’s argument is rooted in the notion of the sentencing package doctrine as it existed pre-Guidelines. The government contends that interdependence arises from the district court’s discretion in crafting an overall sentence designed to punish the criminal and his conduct rather than from the workings of the Guidelines.- Aside from the possibility that this argument, predicated on a sentencing court’s discretion, may be foreclosed by the Guidelines, it is not apparent that the elastic notion of interdependence that the government advocates has
ever
been supportable under the sentencing package doctrine. Even pre-Guidelines, courts expressed concern with the application of the doctrine to concurrent sentences.
See McClain v. United States,
As the foregoing makes clear, the application of the sentencing package doctrine to the concurrent sentences involved in this case is by no means a foregone conclusion. However, as we explain, this case does not turn on an application of the sentencing package doctrine, and thus we intimate no view on whether the government’s broad conception of interdependence is ultimately supportable—leaving that decision to another day.
. “The Supreme Court or any other court of appellate jurisdiction may affirm, modify, vacate, set aside or reverse any judgment, decree, or order of a court lawfully brought before it for review, and may remand the cause and direct the entry of such appropriate judgment, decree, or order, or require such further proceedings to be had as may be just under the circumstances.” 28 U.S.C. § 2106 (emphasis supplied).
. We exercise plenary review over challenges to the legality of a sentence imposed by a district court.

. We also exercise plenary review over the district court’s construction of the Sentencing Guidelines.
