This appeal arises out of a decision of the United States District Court for the Western District of New York (David G. Larimer, Judge), on a remand pursuant to
United States v. Crosby,
On appeal, defendant Art Williams argues that the District Court used the
*471
wrong legal standard when determining whether to resentence him pursuant to
Crosby,
and that his 216-month sentence was unreasonable under the standard of appellate review set forth in
United States v. Booker,
The parties’ submissions require us to consider the scope of our review of a district court’s decision not to resentence pursuant to Crosby. We conclude that we retain authority to review for reasonableness both the procedure whereby the District Court decided not to resentence and the substance of the undisturbed sentence. We clarify, however, that the law of the case doctrine forecloses reconsideration of issues that were decided — or that could have been decided — during prior proceedings.
In the matter of defendant Williams, we find no reversible error in the District Court’s proceedings on the Crosby remand, and we conclude that the sentence imposed on Williams by the District Court was reasonable. We dismiss the appeal of Williams’s co-defendant Onaghinor as moot.

I. Facts and Procedural History 1
In November 2001, defendants Art Williams and Roland Onaghinor were convicted by a jury for their participation in a conspiracy to possess with intent to distribute, and to distribute, one kilogram or more of heroin, in violation of 21 U.S.C. §§ 841(a)(1), 841(b)(1)(A), and 846. Defendant Williams was also convicted of thirteen counts of using a communication facility (the U.S. Mail) in committing, or in causing or facilitating the commission of, the heroin trafficking conspiracy, in violation of 21 U.S.C. § 843(b) and 18 U.S.C. § 2.
At their sentencings, which were conducted under the then-mandatory Sentencing Guidelines regime governing federal sentencing, the District Court made a number of rulings favorable to both Williams and Onaghinor, the net result of which was to reduce substantially the Guidelines range applicable to their offenses. For example, the District Court held that Williams could only be held responsible for conspiring to distribute between 700 grams and 1 kilogram of heroin, despite a jury finding that he was responsible for conspiring to distribute, over 1 kilogram of heroin. This ruling, along with other favorable findings by the District Court, reduced Williams’s potential sentence for the heroin trafficking conspiracy conviction from a mandatory sentence of life imprisonment without parole, see 21 U.S.C. § 841(b)(1)(A), 2 to a Guidelines *472 range of 188 to 235 months. The District Court also affirmed, over the Government’s objection, a jury finding that Ona-ghinor could not be held responsible for conspiring to distribute more than 100 grams of heroin. The District Court did, however, impose a two-level enhancement for obstruction of justice pursuant to U.S. Sentencing Guidelines Manual (“U.S.S.G.”) § 3C1.1 on both Williams and Onaghinor, and a three-level enhancement on Williams for his role in the offense pursuant to U.S.S.G. § 3Bl.l(b).
The District Court sentenced Williams on March 5, 2003 to a term of imprisonment of 216 months on the heroin trafficking conspiracy count, and a term of imprisonment of 48 months on each of the remaining counts, each term of imprisonment to run concurrently with the others. He was also sentenced to three years of supervised release, a fine of $3,000 on count one, and a special assessment of $1,400. Onaghinor was sentenced on May 16, 2002 to a term of imprisonment of 78 months, a period of supervised release of three years, and a $100 special assessment.
On appeal, we affirmed defendants’ convictions and rejected Williams’s challenge to the District Court’s imposition of the two-level obstruction of justice enhancement,
see Peterson,
On remand, Williams asked the District Court to “reconsider ... the application” of the Guidelines enhancements that it had imposed on him for obstruction of justice and his role in the offense. While Williams’s sentencing memorandum sought to convince the District Court that Williams had not obstructed justice, it did not argue that any of the sentencing factors set forth in 18 U.S.C. § 3553(a) and given renewed vitality by
Booker/Fanfan, see Crosby,
II. The District Court’s Decision
In a published Decision and Order dated August 24, 2005, the District Court declined to resentence either defendant.
See United States v. Williams,
I understand that the Sentencing Guidelines are now advisory and that the Court must consider them and impose a reasonable sentence after considering all the factors listed at 18 U.S.C. § 3553(a). If the sentencing were to occur today in light of the new sentencing regime in effect since the Booker Supreme Court case, I would make the same findings as to the Guidelines and impose the same sentence....
In sum, I see no reason to order a resentencing in this case since if we were do so [sic ], my sentence would be the same and would not be affected by the fact [that] the Sentencing Guidelines are now advisory and not mandatory.
Id. The District Court rejected Onaghi-nor’s request for resentencing using simi *474 lar language, concluding that “[wjhether the Guidelines were mandatory or advisory, it would make no difference in determining what the appropriate reasonable sentence should be. Therefore, I decline to resentence Roland Onaghinor and believe that the original sentence was proper and is a reasonable sentence under the Sentencing Guidelines and § 3553(a).” Id. at 428.
III. Arguments on Appeal and Subsequent Developments
Both defendants appealed the District Court’s decision not to resentence pursuant to
Crosby.
Defendant Williams alleges on appeal that the District Court used the improper legal standard when determining whether to resentence, and that the sentence imposed by the District Court was unreasonable. Counsel for defendant Ona-ghinor moved to be relieved as counsel pursuant to
Anders v. California,
On July 10, 2006, Onaghinor completed his sentence of imprisonment and commenced service of his term of supervised release. In response to our inquiry at oral argument into Onaghinor’s whereabouts, the Government informed us by supplemental letter dated January 16, 2007, that Onaghinor was deported to Nigeria on December 12, 2006.
Discussion
I. Scope of Our Review of a Decision not to Resentence Pursuant to Crosby
Before adjudicating defendants’ appeals, we clarify the scope of our review when a district court has declined to resentence a defendant upon a Crosby remand.
Pursuant to the Supreme Court’s opinion in
Booker/Fanfan,
we review sentences for reasonableness.
See Booker/Fanfan,
We hold here that we review a sentence for reasonableness even after a District Court declines to resentence pursuant to
Crosby.
We do so because we are “obliged to apply
Booker/Fanfan
to this case ... [which] is pending on direct review.”
Crosby,
Our approach also finds support from other Circuits that have followed
Crosby.
For example, in
United States v. Paladino,
We note, however, that by the time a district court’s decision not to re-sentence pursuant to
Crosby
reaches us on appeal, at least two claims of error related to the sentencing will normally be foreclosed by prior proceedings. First, as we indicated in
Crosby,
any errors in the procedure for selecting the original sentence under the then-mandatory Guidelines regime “would be harmless, and not prejudicial under plain error analysis, if the judge decides on remand, in full compliance with now applicable requirements, that under the
post-Booker/Fanfan
regime the sentence would have been essentially the same as originally imposed.”
Crosby,
Second, the law of the case doctrine ordinarily will bar a defendant from renewing challenges to rulings made by the sentencing court that were adjudicated by this Court — or that could have been adjudicated by us had the defendant made them — during the initial appeal that led to the
Crosby
remand.
See United States v. Quintieri,
The law of the case doctrine will not, however, bar a defendant who is not resentenced after a
Crosby
remand from challenging the procedures used by the district court during the
Crosby
remand. This is so because the doctrine does not prevent a defendant from raising a sentencing issue “if it arises as a result of events that occur after the original sentence.”
Quintieri,
In addition, the law of the case usually will not prevent a defendant who appeals a district court’s decision not to resentence pursuant to
Crosby
from obtaining reasonableness review of the length of his sentence. In remanding under
Crosby,
we generally decline to consider whether the sentence of a defendant is unreasonably long because of the possibility that a different sentence will be imposed after the
Crosby
remand.
See Crosby,
II. Analysis
Having clarified the standards guiding our review of a decision not to resentence made by a district court after a Crosby remand, we proceed to address defendants’ appeals.
A. Williams’s Appeal
Williams first argues that the District Court erred by failing to comply with the dictates of § 3553(a) in deciding not to resentence him. Specifically, Williams asserts that the District Court improperly stated that it was obligated to “impose a reasonable sentence after considering” the § 3553(a) factors, when in fact, the District Court’s duty under § 3553(a) is to “impose a sentence sufficient, but not greater than necessary, to comply with the purposes set forth in” § 3553(a)(2).
See
note 3,
ante
(quoting 18 U.S.C. § 3553(a)). The “sufficient, but not greater than necessary” clause is known as the “parsimony clause” of § 3553(a).
See United States v. Ministro-Tapia,
We have recognized that district courts are to impose sentences pursuant to the requirements of § 3553(a) — including the requirements of § 3553(a)’s parsimony clause — while appellate courts are to review the sentences actually imposed by district courts for reasonableness.
See
*477
Ministro-Tapia,
We nonetheless decline to order a second
Crosby
remand for two reasons. First, there is no indication that the District Court actually failed to consider the requirements of the parsimony clause when deciding whether to resentence Williams pursuant to
Crosby.
To the contrary, the District Court explicitly stated that it was considering all of the § 3553(a) factors in determining whether to resen-tence defendants,
see Williams,
Second,
Williams
has failed to demonstrate that the District Court’s reference to the
appellate
standard of review when deciding whether to resentence him constituted reversible error.
See Ministro-Tapia,
Williams also argues on appeal that the 216-month term of imprisonment imposed by the District Court was unreasonably long, primarily because his age (he is 56 years old) allegedly reduces the risk that he will be a repeat offender if he were released from prison. In addition, Williams contends that his sentence was overly long because of the impact that his sentence is having on his children, and because a shorter sentence would still permit him to pursue necessary educational or vocational training, medical care, and cor *478 rectional treatment — including treatment for his drug addiction.
Although Williams’s sentence was substantial, we conclude, upon consideration of the entire record, that his sentence was “well within the broad range of reasonable sentences that the District Court could have imposed in the circumstances presented.”
Fernandez,
B. Onaghinor’s Appeal
Under the teaching of
Anders v. California,
In support of the [Anders ] motion, defense counsel must supply a brief identifying by record references any issues that have at least arguable merit supported by legal authority, and explain why they are frivolous. See United States v. Burnett,989 F.2d 100 , 103 (2d Cir.1993). This Court will not grant a so-called Anders motion unless it is satisfied that (1) “counsel has diligently searched the record for any arguably meritorious issue in support of his client’s appeal,” and (2) “defense counsel’s declaration that the appeal would be frivolous is, in fact, legally correct.” Id. at 104.
While the brief accompanying Onaghi-nor’s counsel’s Anders motion fails to address whether there would be any non-frivolous basis for challenging the reasonableness of Onaghinor’s sentence, 5 we need not decide here whether the brief fails to comply with the requirements of Anders because Onaghinor’s appeal was rendered moot by the completion of his term of incarceration.
“A case becomes moot when it no longer satisfies the ‘case-or-controversy’ requirement of Article III, Section 2 of the Constitution. In order to satisfy the case-
*479
or-controversy requirement, a party must, at all stages of the litigation, have an actual injury which is likely to be redressed by a favorable judicial decision.”
United States v. Mercurris,
In
Blackburn,
we noted that several other Circuits “have held that a challenge to a sentence by a criminal defendant who has completed his prison term but remains subject to supervised release is not moot because the possibility of the district court’s reducing the term of supervised release on remand gives the defendant-appellant a continuing stake in the outcome.”
Blackburn,
We conclude that Onaghinor’s appeal was rendered moot upon his release from prison because there is no possibility that the district court could impose a reduced term of supervised release were we to remand for resentencing. Onaghinor was convicted of participation in a conspiracy to distribute heroin, a Schedule I substance, see 21 U.S.C. § 812, and the District Court was required to “impose a term of supervised release of at least 3 years,” 21 U.S.C. § 841(b)(1)(C), on Onaghinor upon his conviction. See id. (establishing penalties for a person who is convicted of possessing with intent to distribute a “a controlled substance in schedule I or II”); 21 U.S.C. § 846 (making the penalties of 21 U.S.C. § 841(b)(1)(C) applicable to Ona-ghinor’s conspiracy conviction). Onaghi-nor received the statutory minimum 3 years of supervised release. Were we to remand, the District Court could not impose a lesser term. 6
Conclusion
For the reasons stated above, we affirm defendant Williams’s sentence, and we dismiss defendant Onaghinor’s appeal.
Notes
. The factual background, of this case is thoroughly recounted in our earlier opinion following defendants’ conviction and initial sentencing. See
United States v. Peterson,
. 21 U.S.C. § 841(b)(1)(A) states, inter alia, that if a person is convicted of possessing with intent to distribute more than 1 kilogram of heroin "after two or more prior convictions for a felony drug offense have become final, such person shall be sentenced to a mandatory term of life imprisonment without release.” *472 Williams was subject to this penalty because the jury had found, in answer to written interrogatories, that Williams had conspired to distribute, or to possess with the intent to distribute, over 1 kilogram of heroin, Williams had been convicted of two drug offenses prior to the date of his conspiracy conviction, and 21 U.S.C. § 846 made the penalties of 21 U.S.C. § 841(b)(1)(A) applicable to his conspiracy conviction. See 21 U.S.C. § 846 ("Any person who attempts or conspires to commit any offense defined in this subchapter shall be subject to the same penalties as those prescribed for the offense, the commission of which was the object of the attempt or conspiracy.”).
. 18 U.S.C. § 3553(a) states as follows:
Factors to be considered in imposing a sentence. — The court shall impose a sentence sufficient, but not greater than necessary, to comply with the purposes set forth in paragraph (2) of this subsection. The court, in determining the particular sentence to be imposed, shall consider—
(1) the nature and circumstances of the offense and the history and characteristics of the defendant;
(2) the need for the sentence imposed—
(A) to reflect the seriousness of the offense, to promote respect for the law, and to provide just punishment for the offense;
*473 (B) to afford adequate deterrence to criminal conduct;
(C) to protect the public from further crimes of the defendant; and
(D) to provide the defendant with needed educational or vocational training, medical care, or other correctional treatment in the most effective manner;
(3) the kinds of sentences available;
(4) the kinds of sentence and the sentencing range established for—
(A) the applicable category of offense committed by the applicable category of defendant as set forth in the guidelines—
(i) issued by the Sentencing Commission pursuant to section 994(a)(1) of title 28, United States Code, subject to any amendments made to such guidelines by act of Congress (regardless of whether such amendments have yet to be incorporated by the Sentencing Commission into amendments issued under section 994(p) of title 28); and
(ii) that, except as provided in section 3742(g), are in effect on the date the defendant is sentenced; or
(B) in the case of a violation of probation or supervised release, the applicable guidelines or policy statements issued by the Sentencing Commission pursuant to section 994(a)(3) of title 28, United States Code, taking into account any amendments made to such guidelines or policy statements by act of Congress (regardless of whether such amendments have yet to be incorporated by the Sentencing Commission into amendments issued under section 994(p) of title 28);
(5) any pertinent policy statement—
(A) issued by the Sentencing Commission pursuant to section 994(a)(2) of title 28, United States Code, subject to any amendments made to such policy statement by act of Congress (regardless of whether such amendments have yet to be incorporated by the Sentencing Commission into amendments issued under section 994(p) of title 28); and
(B) that, except as provided in section 3742(g), is in effect on the date the defendant is sentenced.
(6) the need to avoid unwarranted sentence disparities among defendants with similar records who have been found guilty of similar conduct; and
(7) the need to provide restitution to any victims of the offense.
. We need not consider here what effect the law of the case doctrine might have on a defendant who is resentenced pursuant to Crosby.
. The
Anders
brief stated that any claims on appeal would be foreclosed “in light of this Court’s limited Mandate in this matter.” The mandate issued in connection with the
Crosby
remand stated, in relevant part, that "[a]ny appeal taken from the district court following this remand will be confined to issues arising from that resentencing, if it occurs.” While we do not fault Onaghinor's counsel's reading of the mandate, to the extent the mandate suggests that no appeal was permissible from the District Court’s decision not to resentence defendants, it squarely contradicts
Crosby's
statement that this Court will have jurisdiction to consider a subsequent appeal "from whatever final decision the District Court makes” upon a
Crosby
remand.
Crosby,
. We note that a separate and independent ground would support a finding that Onaghinor’s appeal was moot. In
United States v. Mercurris,
