Thе defendant-appellant Carlo Donato was resentenced by the United States District Court for the Eastern District of New York (Jacob Mishler, Judge) upon remand after a decision of this court vacating his first sentence. Donato appeals on a variety of grounds. In order to decide this appeal, we must address knotty questions that emerge when an appeal results in a remand for resentencing. The difficulty arises largely from the apparent tension
*1222
between the view, adverted to in
United States v. Atehortva,
69 F.Bd 679, 685 (2d Cir.1995),
cert. denied sub nom. Correa v. United States,
Donato appeals from the sentence imposed on him by the district court following our remand of the case for resentenc-ing because it appeared that, at Donato’s first sentencing, “double counting” may have improperly increased his offense level on one count. On remand, the district court concluded that it had indeed improperly increased Donato’s offense level and, accordingly, reduced his sentence. The defendant argues on appeal:. (1) through counsel, (a) that the district court was required to hold a hearing to determine whether he was competent to be resen-tenced, (b) that the district court was required to order a new presentence investigation report (“PSR”) before resentencing him, (c) that the district court improperly failed to consider the required factors before ordering restitution and a fine, and (d) that the amount of the fine was in error; and (2)
pro se,
(a) that the district court improperly failed to consider his motion for a downward departure, and (b) that his sentence violates the rule of
Apprendi v. New Jersey,
As the government concedes, the district court erred when it imposed a fine above the amount prescribed by the Guidelines without explaining its reasons for a departure. We conclude that all of Donato’s other arguments are either barred by the law of the case or without merit.
BACKGROUND
In separate incidents in 1993 and 1994, Donato carjacked three Mercedes Benz and three BMW vehicles, each time threatening his victim with a gun. For these robberies, a jury convicted Donato in 1996 of one count of conspiracy to commit carjacking in violation of 18 U.S.C. § 371, six counts of carjacking in violation of 18 U.S.C. § 2119, and six counts of using a firearm in furtherance of a crime of violence in violation of 18 U.S.C. § 924(c). Based on a combined total offense level of thirty-two and a criminal history category of II, the district court sentenced Donato to 168 months’ (fourteen years’) imprisonment on the one count of conspiracy to commit carjacking and the six substantive carjacking counts. 1 Donato was also sen *1223 tenced to 105 years on the firearm counts, five years for the first count and twenty years for each subsequent count pursuant to 18 U.S.C. § 924(c)(1), as then in effect, to be served consecutively to each other and to the carjacking sentence. The defendant’s aggregate prison term was therefore 119 years. He was also ordered to serve three years of supervised releasе 2 and to pay a $175,000 fine and $295,807.25 in restitution.
On April 23, 1997, we affirmed Donato’s convictions in an unpublished order.
United States v. Donato,
On remand, after consultation with the probation department, the government conceded that Donato’s combined total offense level on the conspiracy count had been improperly enhanced as a result of “double counting.” The government told the court that Donato’s combined total offense level on the conspiracy count and the carjacking counts should therefore have been twenty-nine, not thirty-two. Dona-to’s combined total offense level for these counts would then have to have been recalculated pursuant to the grouping provisions contained in U.S.S.G. §§ 3Dl.l(a) and 3D 1.4, which provide for the calculation of a combined offense level by taking the offense level applicable to the count with the highest offense • level and then adding levels to account for the fact that multiple counts are involved. At the original sentencing, according to the PSR, the *1224 conspiracy count had the highest offense level. But after removing the improper enhancement for possession of a firearm, that was no longer the case. One of the substantive counts for carjacking now had the highest offense level — twenty-four. This level was calculated by enhancing the base offense level of twenty, U.S.S.G. § 2B3.1(a), by two levels because the robbery involved carjacking, § 2B3.1(b)(5), and then by two more levels because the loss amount was more than $50,000, § 2B3.1(b)(7)(C). The government then arrived at a combined total offense level of twenty-nine for all seven convictions by adding five additional levels to account for Donato’s additional six crimes with offense levels within four levels of the carjacking count with the highest offense level. See U.S.S.G: § 3D1.4(a). 3 Because Donato’s criminal history category was II, the applicable Guideline range for the conspiracy and carjacking counts was now 97 to 121 months. As before, this sentence would run consecutively to the 105-year prison term on the firearm counts. 4
At the resentencing hearing on December 1, 2000, defense counsel “concurred” in the government’s sentencing analysis but asked the court to downwardly depart for post-conviction rehabilitation. Defense counsel also asked the court to consider Donato’s pro
se
sentencing memorandum that argued that his sentence violates the rule of
Apprendi v. New Jersey,
When asked if he wished to make a statement, Donato said that he felt “dizzy" and was not well enough to be at the hearing because his psychiatric medications had been “mix[ed] up” the previous day. Hr’g Tr. of Dec. 1, 2000; at 4. Defense counsel stаted that based on three conversations with Donato the previous day and a review of his medical records, she thought that while he did not “feel[ ] well” he was nonetheless “lucid and able to continue with the sentencing.” Id. at 5. Defense counsel also reported that Donato “[was] well oriented as to time and place and fully understood] the purpose of [the] procedure.” Id. No one present at the resen-tencing hearing requested a competency hearing.
The district court then resentenced Do-nato to the same term as it had the first time, except that to correct for the “double counting,” the court reduced Donato’s sentence on the conspiracy and carjacking counts to 120 months (ten years) — one month shy of the top of the sentencing range. He therefore received an aggregate prison sentence of 115 years — ten years for conspiracy and carjacking plus 105 years for the firearm offenses. Additionally, the court sentenced him to three *1225 years’ supervised release, a $175,000 fine, and $295,807.25 in restitution.
This appeal followed.
DISCUSSION
I. The Issues Properly Before Us
As noted, the issues Donato raises on appeal are: (1) through counsel, (a) whether the district court was required to hold a hearing to determine whether he was competent to be resentenced, (b) whether the district court was required to order a new PSR before resentencing him, (c) whether the district court improperly failed to consider the required factors before ordering restitution and a fine, and (d) whether the amount of the fine was in error; and (2)
pro se,
(a) whether the district court improperly failed to consider his motion for a downward departure, and (b) whether his sentence violates the rule of
Apprendi v. New Jersey,
The law оf the case doctrine has two branches. The first requires a trial court to follow an appellate court’s previous ruling on an issue in the same case.
United States v. Uccio,
The “mandate rule” ordinarily forecloses relitigation of all issues previously waived by the defendant or decided by the appellate court. But when a case is remanded for
de novo
resentencing, the defendant may raise in the district court and, if properly preserved there, on appeal to the court of appeals, issues that he or she had previously waived by failing to raise them.
See United States v. Stanley,
Donato seeks to raise some issues that he waived by not raising them during his initial sentencing proceedings or. on his previous appeal. We must therefore determine at the outset whether Donato’s case was remanded for de novo or for limited resentencing. We conclude that in this case, because we identified a particular sentencing issue necessitating remand—whether Donato’s total offense level on the conspiracy count was improperly enhanced as a result of. “double counting”—the remand was limited, not de novo. Because the remand was limited, Donato may not now raise arguments that he had an incentive and an opportunity to raise previously but did not raise, absent a cogent and compelling reason for permitting him to do so.
A. Whether Donato’s Resentencing Was De Novo
When Donato’s case was last before us, we remanded it to the district court for resentencing because we had
*1226
identified a possible' sentencing error— “double counting.”
Donato II,
[T]here may have been improper double counting if the district court increased the offense level for the conspiracy count because of the firearm possession charged as an overt act in Count One, and then sentenced Donato to a five-year consecutive sentence under section 924(c) for the use and possession of a firearm during the commission of the carjacking charged in Count Two. We therefore remand to the district court for resentencing in light of this order, without prejudice to the government submitting an argument to the district court explaining why this was not double-counting.
We have considered Donato’s • other claims and find them to be without merit.
The judgment of the district court is hereby AFFIRMED in part and REMANDED in part.
Id. (emphasis added). This remand order neither explicitly stated that the sole issue on remand was whether' “double counting” affected Donato’s sentence on the conspiracy count, nor indiсated that we intended a de novo resentencing or were leaving any issues open for the district court’s further consideration other than whether “double counting” improperly affected Donato’s total offense level'.
In
Stanley II,
we held that a similar mandate did not allow for
de novo
resen-tencing.
In sum, because the district court failed to indicate whether its loss calculation was based on actual or intended loss, and failed to make sufficient factual findings supporting either calculation, we remand for resentencing. If upon reconsideration, the district court’s sentencing calculation results in a determination of loss different from that originally found, the district court may wish to also recalculate the amount of restitution and make findings as to that issue. We have examined Stanley’s remaining contentions regarding his sentence and find them to be without merit.
CONCLUSION
Based on the foregoing, we affirm defendant’s conviction, but vacate and remand this case for further sentencing proceedings consistent with this opinion.
Id.
(emphasis added).' On appeal after remand and resentencing, we read our original mandate as effecting a limited remand on the sole issue of whether the loss amount was properly calculated. We concluded that the mandate of the
Stanley I
panel “did not call for
de novo
resentenc-ing. Instead, we'identified a narrow issue for remand .... ”
Stanley II,
Our remand order in
Donato II
does not differ in any material respect from the remand order in
Stanley I.
Both identified a specific sentencing error, remanded because of that error, and decided that all other claims were without merit. We therefore conclude that the remand in
Donato II
was not for
de novo
resentenc-ing and that accordingly Donato may not now raise arguments that he waived by not making them on his previous appeal. This holding is consistent with our repeated statement that to determine whether a remand is
de novo,
we must “look to both the specific dictates of the remand order as well as the broader ‘spirit of the mandate.’ ”
United States v. Ben Zvi,
At first glance, a decision of ours handed down several months after
Stanley II, United States v. Atehortva,
[B]ecause the resentencing was based on a different set of circumstances, the court was free to consider grounds for departure it had not contemplated in the first sentencing proceeding. That is, the resentencing proceeding was appropriately treated as a de novo sentencing, for the remand did not specifically limit the scope of resentencing.
Id. at 685. This seems to suggest that sentencing must proceed de novo unless a court “specifically limit[s] the scope of re-sentencing.”
But Atehortva’s holding is properly limited to cases where one or more convictions have been vacated and we have remanded for resentencing on the remaining counts. In Atehortva, we explained:
When a defendant challenges convictions on 'particular counts that are inextricably tied to other counts in determining the sentencing range under the guidelines, the defendant assumes the risk of undoing the intricate knot of calculations should he succeed. Once this knot is undone, the district court must sentence the defendant de novo ....
Id.
at 685-86 (citation omitted; emphasis added). A district court’s sentence is based on the constellation of offenses for which the defendant was convicted and their relationship to a mosaic of facts, including the circumstances of the crimes, their relationship to one another, and other relevant behavior of the defendant. When the conviction on one or more charges is overturned on appeal and the case is remanded for resentencing, the constellation of offenses of conviction has
*1228
been changed and the factual mosaic related to those offenses that the district court must consult to determine the appropriate sentence is likely altered. For the district court to sentence the defendant accurately and appropriately, it must confront the offenses of conviction and facts anew. The offenses and facts as they were related at the first sentence may, by then, have little remaining significance. The “spirit of the mandate” in such circumstances is therefore likely to require
de novo
resentencing.
See Bryce,
That resentencing usually should be de novo when a Court of Appeals reverses one or more convictions and remands for resentencing, then, does not deviate from the rule applied in Stanley II that absent explicit language in the mandate to the contrary, resentencing should be limited when the Court of Appeals upholds the underlying convictions but determines that a sentence has been erroneously imposed and remands to correct that error. To be sure, there may be circumstances when we reverse a sentence in which the “spirit of the mandate” requires de novo sentencing, for example when the reversal effectively undoes the entire “knot of calculation,” but this is not such a case. 6
*1229 B. The Implications of a Limited Remand
Applying these principles, the remand in this case was limited to the issue of “double counting.” The law of the case doctrine therefore dictates what issues may be raised in the district court and on any subsequent appeal.
See Stanley II,
An issue is not considered waived, however, if a party did not, at the time of the purported waiver, have both an opportunity and an incentive to raise it before the sentencing court or on appeal.
See United States v. Ticchiarelli,
Furthermore, and importantly, even when a remand is limited, an issue may be raised if it arises as a result of events that occur after the original sentence.
See United States v. Bryson,
Finally, even if an issue is barred by the law of the case, appellate courts may depart from the law of the case and reconsider the issue for “cogent” and “compelling” reasons such as “an intervening change of controlling law, the availability of new evidence, or the need to correct a clear error or prevent manifest injustice.”’
United States v. Tenzer,
C. Application of the Law of the Case to Donato’s Limited Mandate
Several of the arguments Donato raises on appeal are barred by the law of the case.
Donato’s argument that the district cоurt failed to consider the required factors before imposing restitution and a fine is barred by the law of the case. To the extent that Donato challenges the procedure followed at the original sentencing, this argument is foreclosed because he had an incentive and an opportunity to challenge these procedures during his previous appeal but did not do so. And because the remand for resentencing was limited, the district court was barred from reconsidering the propriety of imposing restitution and a fine. Thus, the district court did not err at the resentencing by reimposing restitution and a fine without first reconsidering on the record the required factors.
Donato’s assertions that his sentence violates the Eighth Amendment and the rule of
Apprendi v. New Jersey,
[23] Finally, Donato’s assertion that the district court violated U.S.S.G. § 2K2.4 by increasing his offense level on the carjacking and conspiracy counts to account for “special offense characteristics” is not properly before us because Dоnato did not make that assertion on his previous appeal even though the offense level on each of the carjacking and conspiracy counts had an impact on his sentence then. While at the original sentencing his combined total offense level for those counts was determined primarily based on his offense level for the conspiracy count, his offense level *1232 on the carjacking counts affected his combined total offense level. 9 See U.S.S.G. § 3D1.4. Thus, having had both opportunity and incentive to mount this challenge the first time around and having failed to do so, Donato cannot do so now.
Four of Donato’s arguments are not barred by the law of the case, however. Two of them—whether the district court should have held a hearing to determine whether Donato was mentally competent at the resentencing and whether the district court should have ordered a new PSR before resentеncing him—arise from events that occurred after the last appeal and therefore are not barred. And to the extent that Donato argues that he should receive a downward departure for rehabilitation that occurred subsequent to his initial sentencing, this argument is similarly not barred because it is based on “intervening circumstances.”
Bryson,
We also conclude that Donato’s argument that the amount of the fine.is in error is not barred by the law of the case. Pursuant to U.S.S.G. § 5E1.2, Donato’s fine is determined based on his offense level. Because of the “double counting”—■ the correction of which was the purpose of the remand—Donato’s offense level and consequently' his fine was too high at the first sentencing. We think that correcting the amount of the fine, after correcting the offense level on which it was based, was well within the limitation placed on the remand.
We will therefore now consider the four arguments properly before us.
II. Procedural Competency
A. ■ Legal Standard
“It is, well established that the Due Process Clause -of the Fourteenth Amendment prohibits the criminal prosecution of a defendant who is not competent to stand trial.”
Medina v. California,
“There are, of course, no fixed or immutable signs which invariably indicate the need for further inquiry to determine fitness to proceed .... ”
Drope v. Missouri,
B. Analysis
Donato, through counsel, contends that the district court should have held a hearing to determine his competence after he complained that he felt dizzy because prison officials administered the wrong psychiatric medication. Certainly, the imprоper administration of psychiatric medicine can render an individual temporarily incompetent.
Riggins v. Nevada,
The district court was able to observe Donato’s demeanor and had the benefit of hearing directly his brief statemеnt at.sentencing. Additionally, Donato’s attorney stated that she had spoken with him three times the previous day, after the mismedi-cation, and that while he appeared to be suffering unfortunate effects from the medicine, he was lucid and able to understand the proceedings. These assurances, combined with the court’s own observations, overcome any reasonable doubt as to the defendant’s competence that may have *1234 been raised by his statement that he felt dizzy. 10
III. Presentence Investigation Report
Donato, through counsel, next argues that the district court violated Fed. R.Crim.P. 32(b) by resentencing him without an updated PSR. Because Donato did not object to the use of the original PSR at the time of resentencing, we review its use for plain error.
See United States v. Thomas,
Rule 32(b) provides:
Presentence Investigation and Report (1) When Made. The probatiоn officer must make a presentence investigation and submit a report to the court before the sentence is imposed, unless:
(A) the court finds that the information in the record enables it to exercise its sentencing authority meaningfully under 18 U.S.C. § 3553; and
(B) the court explains this finding on the record.
We have held that Rule 32 does not require “ ‘an updated PSR in the event of
resentencing
’ ” if, for example, “the parties are given a full opportunity to be heard and to supplement the PSR as needed .... ”
United States v. Triestman,
Donato was provided a full opportunity to supplement the original PSR, and the need for an updated PSR was not readily *1235 apparent. The government, the probation department, and Donato all agreed on the resolution of the “double counting” issue. The defendant submitted a detailed letter updating the court on his conduct while incarcerated. And the court provided the defendant, as well as his counsel, an opportunity to speak at the resentencing hearing. In rеtrospect, an updated PSR might have been useful because the probation department might have noticed, as we explain below, that the fine was miscalculated. But because the defendant did not object to the amount of the fine, we cannot fault the district court for failing to order a new PSR to address that issue.
TV. Downward Departure
Donato’s pro se argument that the district court failed to consider his motion for a downward departure based on post-sentencing rehabilitation is without merit. The court considered and rejected this motion on its merits. Parenthetically, the court was plainly correct in denying it. Donato and the government agree that the Guidelines effective November 1, 2000 apply to the resentencing, and U.S.S.G. § 5K2.19 of the Guidelines as of that date prohibits a downward departure based on post-sentencing rehabilitative efforts.
V. The Amount of the Fine
The government concedes that the amount of the fine is in error. On remand for resentencing, the parties agreed that Donato’s previously determined offense level of thirty-two was improper due to “double counting” and that his total offense level is 'twenty-nine. Pursuant to U.S.S.G. § 5E1.2(c)(3), a defendant with a total offense level of twenty-nine is subject to a fine between $15,000 and $150,000. The court, however, reimposed the original fine of $175,000, which is an appropriate fine under the Guidelines only for offense levels of thirty-two' or greater.
See
U.S.S.G. § 5E1.2(c)(3). Because the district court imposed a fine above the Guideline range without explaining its reason for the departure, the $175,000 fine was clearly- imposed in error.
See
18 U.S.C. § 3353(c)(2) (stating that the court must, at time of sentencing, provide explanation for departure from guidelines range). Even though Donato did not object to the amount of the fine in the district court, a limited remand for the purpose of redetermining the amount of the fine is necessary because the error was plain, it affects Do-natо’s substantial rights, and failing to correct the error would seriously affect the fairness of the judicial proceedings.
See Thomas,
CONCLUSION
For the foregoing reasons, we affirm in part, but vacate the imposition of the fine and remand to the district court for the limited purpose of imposing a fine within the appropriate Guideline range, or imposing a fine above the Guideline range with appropriate explanation.
Notes
. Donato’s combined total offense level for the one count of carjacking conspiracy and the six counts of carjacking was calculated pursuant to U.S.S.G. §§ 3Dl.l(a) and 3D1.4, which provide for the calculation of a combined offense level by taking the offense level applicable to the count with the highest offense level and then adding levels to reflect the existence of multiple counts. The PSR determined that the conspiracy count had the *1223 highest offense level — twenty-seven. This level was calculated by enhancing the base offense level of twenty, U.S.S.G. §§ 2B3.1(a) and 2X1.1(a), by two levels because the conspiracy involved carjacking, § 2B3.1(b)(5), and then by five more levels because of possession of a firearm, § 2B3.1(b)(2)(C). A combined total offense level of thirty-two for all counts was then reached by adding five levels to account for Donato's more than five additional separate crimes, each with offense levels no more than four levels below that of the conspiracy offense. U.S.S.G. § 3D1.4. Because his criminal history category was II, the applicable Guideline range was 135 to 168 months.
. Cognizant of the fact that Donato was unlikely to serve supervised release after completing his 119-year prison sentence, the district court nonetheless ordered a period of supervised release in anticipation of the possibility of a change in the law regarding deportation of incarcerated felons to which the imposition of supervised release might be relevant.
. For purposes of § 3D 1.4(a), the defendant committed six not seven separate crimes because his conviction on the conspiracy count was grouped with his conviction on one of the substantive • counts of carjacking. See U.S.S.G. § 3D1.2(b), cmt. n. 4. Under § 3D 1.4(a), the six crimes required the court .to assess six "units,” which, under that section, in turn called for the five-level enhancement.
. Pursuant to U.S.S.G. § 2K2.4(a)(2), Donato was sentenced originally and at the resentenc-ing to the minimum term of imprisonment required, by 18 U.S.C. § 924(c). At the time he committed the firearm offenses, § 924(c) provided for a mandatory minimum sentence of five years for the • first conviction and a mandatory minimum sentence of twenty years for each subsequent conviction. Donato was therefore sentenced to five years on the first firearm count and twenty years on each of the five other firéarm cоunts. In accordance with U.S.S.G. § 5G1.2(a), these sentences all run consecutively to each other and to the carjacking sentence.
. Technically, the “mandate” of this Court consists of a "certified copy of [our] judgment, a copy of the opinion, and any direction as to costs.”
United States v. Reyes,
.
The circuits are divided as to whether a remand for resentencing should be limited or
de novo
absent explicit direction from the remanding court. The Sixth, Eighth, Ninth, Tenth, and Eleventh Circuits follow a
de novo
sentencing default rule.
See United States v. Jennings,
The D.C., First, Fifth, and Seventh Circuits follow a default rule of limited resentencing.
See United States v. Whren,
*1229
Today we conclude that when a resentenc-ing results from a vacatur of a conviction, we in effect adhere to the
de novo
default rule of the Sixth, Eighth, Ninth, and Eleventh Circuit, because multiple convictions are "inextricably linked” in calculating the sentencing range under the guidelines.
Atehortva,
. Of course, an issue cannot be waived by failure to raise it on аppeal unless it could have been raised on that appeal. For example, a district court's refusal to grant a discretionary downward departure is not appeal-able unless there is evidence in the record that the district court did not recognize its authority to depart downwardly.'
United States v. Schmick,
. Our discussion of which issues may be raised applies only to the resentencing proceeding (whether the resentencing results from a remand after direct appeal or from a successful § 2255 motion) in the district court and a subsequеnt direct appeal. Different concerns may govern whether a § 2255 motion following a resentencing is to be treated as a first or successive habeas petition.
See Galtieri v. United States,
. U.S.S.G. § 3D1.4(a) provides for the in- . crease of the combined offense level by one point for each count with an offense level "equally serious [to] or from 1 to 4 levels less serious” than the count with the highest offense level. But the combined offense level is only increased by one-half a level if the offense level is "5 to 8 levels less serious than the Group with the highest offense level.” § 3D 1.4(b). If Donato had successfully challenged the enhancements for "specific offense characteristics” at the original sentencing, each carjacking count would have increased the combined offense level by one-half instead of one offense level.
. In cases where appellate courts have reversed because of a trial court’s failure to order a competency hearing, the evidence of incompetency was significantly stronger.
