*158This case presents the question of whether the Government breaches a plea agreement when it agrees to an estimated sentence-known as a " Pimentel estimate"-in a defendant's plea bargain, then advocates for a substantially higher sentence at the defendant's sentencing hearing on the basis of information known to the Government at the time of the agreement.
We have previously held that allegations of breached plea agreements depend on what "the reasonable understanding and expectations of the defendant [were] as to the sentence for which he had bargained." Paradiso v. United States ,
We hold that, under these circumstances, Walker could not have reasonably expected that the Government would change its position in such a manner when he consented to the Pimentel estimate in his plea bargain, and therefore that the Government breached the plea agreement. Accordingly, we VACATE Walker's sentence and REMAND for resentencing under the original plea agreement.
BACKGROUND
On October 5, 2010, pursuant to a surveillance operation conducted by the New York Police Department ("NYPD") and the Drug Enforcement Agency ("DEA"), defendant Shondell Walker and two others were arrested during a traffic stop.
That same day, the Government filed a criminal complaint against Walker in the United States District Court for the Eastern District of New York. The complaint stated that "[f]or the past several years, the NYPD and the DEA have been investigating a violent criminal organization based in the Gowanus Houses, a public housing development in the Boerum Hill section of Brooklyn." Compl. ¶ 2. "For the better part of the last three years, these defendants have controlled the distribution of crack cocaine and heroin in the Gowanus Houses." Id. ¶ 2. "During the course of this investigation, law enforcement has, among other things, made numerous undercover purchases of crack cocaine directly from members of this crew." Id. ¶ 3. "In addition, ... NYPD has executed various search warrants and arrested various individuals associated with this organization. These search warrants ... have resulted in the seizure of ... substantial quantities of crack cocaine ...." Id. ¶ 4.
The complaint explained that Walker was "regularly involved in the distribution of crack cocaine in the Gowanus Houses *159for an individual identified as Ronald Herron, who was the leader of this criminal organization." Id. ¶ 6 (capitalization and footnotes removed). Walker "worked with this organization and served as one of Herron's primary security guards and enforcers." Id. ¶ 7. For instance, Walker would "regularly accompany Herron to narcotics transactions and carry firearms for Herron." Id. ¶ 7. "Walker would also help to protect Herron's narcotics territory ... by, for example, robbing or attacking rival narcotics traffickers." Id. ¶ 7. And one cooperating witness "stated that he and Walker participated in a shooting against a rival narcotics trafficker." Id. ¶ 7. Moreover, Walker had previously been arrested in association with this criminal organization when he was discovered in an apartment where the NYPD also found heroine and crack cocaine. Id. ¶ 5.
Walker and eleven other co-defendants were eventually charged in a multi-count indictment for participation in the Gowanus Houses drug conspiracy.
On October 6, 2011, Walker pled guilty-pursuant to a plea agreement with the Government-to a single count of conspiring to distribute at least 200 grams of crack cocaine in violation of
The plea agreement also stated, in relevant part:
3. The Guidelines estimate set forth ... is not binding on the Office, the Probation Department or the Court. If the Guidelines offense level advocated by the Office, or determined by the Probation Department or the Court, is, for any reason, including an error in the estimate, different from the estimate, the defendant will not be entitled to withdraw the plea and the government will not be deemed to have breached this agreement.
...
5. The Office agrees that ... based upon information now known to the Office, it will ...
b. take no position concerning where within the Guidelines range determined by the Court the sentence should fall; and
c. make no motion for an upward departure under the Sentencing Guidelines.
If information relevant to sentencing, as determined by the Office, becomes known to the Office after the date of this agreement, the Office will not be bound by paragraphs 5(b) and 5(c).
App. 91-93.
The Probation Department subsequently prepared a Pre-Sentence Report ("PSR") for Walker on January 3, 2012, in which it agreed with the Government's estimated Guidelines sentence. According to the PSR, Walker worked as an "enforcer" for the conspiracy and "carried a firearm as part of his role in the organization in order to protect himself, the drug proceeds, and the locations on the block where the crack cocaine was sold." PSR ¶ 11. The PSR also reported that, "[p]er the Government, Walker is responsible for distributing 200 *160grams of crack cocaine during the course of the conspiracy between 2007 and 2010,"
After several delays, Walker's sentencing hearing was scheduled for September 10, 2013.
On the day of the hearing, the District Court-at the Government's request, and over defense counsel's objection-postponed Walker's sentencing until after the trial of Walker's co-defendant, Ronald Herron. See United States v. Herron , Docket No. 1:10-cr-00615-NGG-2. At Herron's trial, several witnesses testified about Walker's role in the drug conspiracy: one stated that Walker had said Herron had given Walker "a gun, so he could protect himself," Trial Tr. 2925, June 16, 2014; another testified that Walker served as "muscle" for Herron, Trial Tr. 1724, June 3, 2014; three witnesses said that Walker threatened people to keep them from selling drugs on Herron's turf; and one witness testified that Walker "car[ried a] gun" for Herron, which Walker twice "flashed" in front of the witness, Trial Tr. 2706-14, June 10, 2014. Witnesses also testified that, at the time of Walker's participation in the conspiracy, the organization regularly sold substantial amounts of cocaine.
Walker himself also testified at Herron's trial as a witness for Herron. Walker claimed that he sold drugs only to support himself; denied Herron's involvement in the conspiracy; and stated that Herron was "a positive role model." Trial Tr. 3762-3780, June 23, 2014.
After the Herron trial ended, on October 19, 2016, the Government submitted a second sentencing memorandum to the District Court advocating for a "revised" Guidelines sentence for Walker based on allegedly new information that surfaced during Herron's trial. App. 68, 72, 78. Specifically, the Government asserted (1) that the trial testimony established that "a reasonable estimate of the narcotics attributable to [Walker] would be no less than one kilogram of crack-cocaine, which would result in a base-offense level increase to level 32" from 30,
*161Roughly contemporaneously, Walker's counsel submitted a second sentencing memorandum objecting to the "drastic modification of the original advisory sentencing guidelines" and requesting a Fatico hearing.
Walker's sentencing hearing was finally held on May 30, 2017-six years after he had originally pled guilty. At the hearing, defense counsel objected to each of the Government's additional sentencing enhancements and requested that Walker be sentenced according to the "original guideline range."
The District Court agreed that "there [wa]s [a] preponderance of the evidence to" support the Guidelines sentence adopted by the Government.
DISCUSSION
Walker appeals on two primary grounds. First, he asserts that the Government breached his plea agreement by advocating for a higher sentence at his sentencing hearing than it had agreed to when he pled. Second, Walker argues that postponement of his sentencing hearing for four years while the Government pursued a trial against his co-defendant violated his Fifth Amendment right to a speedy sentencing. See United States v. Ray ,
*162I
"We review interpretations of plea agreements de novo and in accordance with principles of contract law." United States v. Riera ,
The Government argues that we should review this claim for plain error because Walker failed to object before the District Court on the specific grounds that the Government "breached" the plea agreement. But if a defendant objects at a sentencing hearing in a manner "which fairly alerts the court and opposing counsel to the nature of the claim," the objection is "sufficient to preserve [the] argument on appeal," even if the defendant fails to "raise a specific rationale for the objection." United States v. Huggins ,
Walker objected multiple times to the Government's change in position. Walker also made clear that he was objecting to the "drastic modification of the original advisory sentencing guidelines," App. 62, and that he ought to be sentenced according to the "original guideline range" contained in his plea agreement, id. at 116. Moreover, the Government itself acknowledged, both in its second sentencing memorandum and during Walker's sentencing hearing, that it was changing its position from the Guidelines sentence estimated in Walker's plea agreement. But it argued that such a change was justified because of allegedly new information that it developed against Walker in the course of Herron's trial.
Under the circumstances, it is obvious that Walker's objections, as evidenced by the Government's arguments in response, "w[ere] sufficient to apprise the court and opposing counsel of the nature of [Walker's] claims" regarding the impropriety of the Government's change in position. Sprei ,
II
Walker argues on appeal that the Government breached his plea agreement because it (1) advocated for a higher sentence at his sentencing hearing than it had agreed to in his plea agreement, and did so (2) based on information that the Government had in its possession at the time the plea was negotiated. Specifically, Walker contends that the evidence the Government used to support its post-plea base offense level increase, use-of-violence enhancement, and aggravating-role enhancement-i.e. , that Herron's organization distributed at least 1 kilogram of crack cocaine, that Walker used violence as part of his role in the drug conspiracy, and that Walker worked as an "enforcer" for Herron-was information that the Government had at the time the plea bargain was struck. Walker contends that the Government's later use of this evidence to justify a revised Guidelines sentence violated the "estimate[ ]" contained in the plea agreement. App. 90.
*163Walker concedes that his perjurious testimony on behalf of Herron is new information that the Government did not have in its possession at the time it negotiated his plea agreement. Walker nonetheless argues that the Government's removal of the reduction for acceptance of responsibility and application of an obstruction-of-justice enhancement-both based on this perjury-also violated the terms of his plea agreement. While we will find that the Government breached Walker's plea agreement when it advocated for an increased base offense level, a use-of-violence enhancement, and an aggravating-role enhancement, and, on that basis, vacate Walker's sentence and remand for resentencing, we take no position on whether the enhancements based on Walker's perjury were also improper, and leave that issue to the resentencing court.
III
Whether the Government breaches a plea agreement when it later advocates for a higher sentence than that contained in the plea-based on information that the Government knew about at the time the plea was negotiated-is not an unfamiliar issue in this Circuit. See United States v. MacPherson ,
As with other questions of breached plea agreements, to resolve this tension, we look both to the precise terms of the plea agreements and to the parties' behavior. We seek to determine what "the reasonable understanding and expectations of the defendant [were] as to the sentence for which he had bargained." Paradiso ,
Because of this focus on the defendant's reasonable expectations-"rather than technical distinctions in semantics" surrounding the Pimentel estimate, Gammarano v. United States ,
Yet in Palladino ,
In Palladino , the prosecutor who negotiated the plea agreement provided the defendant with a Pimentel estimate that excluded a potentially applicable six-point sentencing enhancement.
In Habbas , we held that the defendant had no such reasonable expectation. In that case, the Government, "under the pressures of preparing a Pimentel estimate after the defendant indicated readiness to plead," simply neglected to "notice the possible applicability of [a four-level sentencing enhancement]."
IV
Given this framework, we find that Walker's reasonable expectations were violated here. First, as in Palladino (and unlike in Habbas ), Walker's plea agreement contained language indicating that the Government would, "based upon information now known to the Office," "make no motion for an upward departure," and it would change its position only if new information "bec[ame] known to the [Government] after the date of th[e plea] agreement." App. 92-93. The agreement also lacked any language like that in Habbas explicitly "reserv[ing] the right" of the Government "to argue for a sentence beyond that called for by the Guidelines."
Second, and significantly, the Government's change in position came about in a manner that Walker could not have reasonably expected when he consented to the Pimentel estimate, and therefore produced "serious unfairness" for Walker. Habbas ,
Despite these problems with Walker's ultimate sentence, the Government argues that it did not breach Walker's plea agreement for two reasons.
First, the Government maintains that Walker's sentence enhancements were based on "new" information, and therefore that it was not bound under the terms of the plea agreement to the original Pimentel estimate. Appellee's Br. 51. But-as shown by a straightforward comparison of (a) the October 2010 criminal complaint *166and the January 2012 PSR with (b) the evidence produced at Herron's trial and enumerated in the Government's October 2016 sentencing memorandum-the information the Government used to justify the increased base offense level, use-of-violence enhancement, and aggravating-role enhancement was in no way new.
1. In its 2016 sentencing memorandum, the Government argued that a two-point base offense level increase was justified based on witness testimony at Herron's trial that "a reasonable estimate of the narcotics attributable to [Walker] would be no less than one kilogram of crack-cocaine." App. 80. But the 2012 PSR said that the Government, at that time, already "conservatively estimate[d] that Herron's organization distributed in excess of 1 kilogram of crack cocaine." PSR ¶ 6. The PSR also reported that law enforcement agents had concluded that "enforcers" (as Walker was labeled) "[we]re responsible for the entire amount of narcotics ... involved in this conspiracy." Id. ¶ 10. And the 2010 criminal complaint indicated that Walker was "regularly involved in the distribution of crack cocaine in the Gowanus Houses," Compl. ¶ 6; that the execution of various search warrants resulted in the seizure of "substantial quantities of crack cocaine" from Herron's organization, id. ¶ 4; and that Walker himself had already been arrested pursuant to such a search warrant, id. ¶ 5.
2. In its 2016 sentencing memorandum, the Government contended that a use-of-violence enhancement was appropriate because of witness testimony at Herron's trial that Walker carried a gun and threatened people that they could not sell drugs on Herron's turf. But the 2010 criminal complaint makes clear that the Government knew then that Walker "served as one of Herron's primary security guards and enforcers"; that he "would thus regularly accompany Herron to narcotics transactions and carry firearms for Herron"; that he "would also help to protect Herron's narcotics territory from rival narcotics traffickers and also help to extend Herron's narcotics territory by, for example, robbing or attacking rival narcotics traffickers"; and that he even "participated in a shooting against a rival narcotics trafficker." Compl. ¶ 7. Moreover, the 2012 PSR also described Walker as "an enforcer" who "carried a firearm as part of his role in the organization in order to protect himself, the drug proceeds, and the locations on the block where the crack cocaine was sold." PSR ¶ 11.
3. In its 2016 sentencing memorandum, the Government asserted that a two-point aggravating-role enhancement was appropriate "given Walker's role as an enforcer in Herron's organization." App. 80. But again, both the 2010 criminal complaint and the 2012 PSR specifically characterized Walker as an "enforcer." Compl. ¶ 7; PSR ¶ 11.
There is little daylight between the information that the Government adduced in Walker's 2016 sentencing memorandum and that contained in the criminal complaint and the 2012 PSR. And the Government essentially admits as much, conceding in its brief on appeal that while it may have had similar information on Walker earlier, it was not "actionable" at the time the Government drafted Walker's plea agreement. Appellee's Br. 53. Actionable or not, the Government knew about Walker's activities and, based on that, made the *167conscious choice to exclude certain enhancements in the Government's Guidelines estimate.
Second, the Government argues that it did not breach Walker's plea agreement because, contrary to Walker's assertions, the Government did not act in bad faith. But we need not find that the Government acted in bad faith in order to hold that Walker's reasonable expectations were violated. Of course, it is "obvious[ly] importan[t]" for the Government to act in good faith when it negotiates a plea agreement, and evidence to the contrary is a strong indicator that the Government violated a defendant's reasonable expectations. Habbas ,
V
The Government further argues that, even if it did breach Walker's plea agreement, Walker cannot show that he suffered any harm from the breach. That argument lacks merit. There is no doubt that the District Court relied on the Government's improperly "revised" Guidelines sentence calculation in imposing Walker's ultimate sentence. And the Supreme Court has instructed that "the [district] court's reliance on an incorrect range in most instances will suffice to show an effect on the defendant's substantial rights." Molina-Martinez v. United States , --- U.S. ----,
*168VI
"In general, the remedy for a breached plea agreement is either to permit the plea to be withdrawn or to order specific performance of the agreement." Vaval ,
In this case, we believe that the appropriate remedy is to order specific performance of the agreement. In Palladino , another case of a breached Pimentel estimate, we concluded that plea withdrawal was the correct remedy because the agreement itself was "hopelessly tainted by the introduction of new evidence known to the Government at the time of the plea."
CONCLUSION
For the foregoing reasons, we VACATE the judgment and REMAND to the District Court for resentencing. We do not doubt Judge Garaufis' capacity to resentence Walker appropriately. But given our holding on the appropriate remedy in the event of a Government breach in Enriquez and in all of the plea agreement violation cases we have found,
The Government also asked that Walker's reduction for acceptance of responsibility be removed and that the enhancement contained in the plea agreement for possession of a dangerous weapon be preserved.
Walker's counsel submitted his second sentencing memorandum on June 14, 2016, in response to an amended PSR that the Probation Department submitted following Herron's trial and in anticipation of a similar submission by the Government. The Probation Department had, in its amended PSR, recommended that Walker's Guidelines sentence be increased following the events at Herron's trial. In Walker's counsel's second sentencing memorandum, counsel objected to the Probation Department's increase from the sentence originally agreed to in his plea agreement, saying that he was "confident" that the Government would similarly advocate for an increased sentence, and arguing that such an increase would also be improper. App. 65. The Government then submitted its second sentencing memorandum on October 19, 2016, arguing for an even higher sentence than that recommended by the Probation Department. Walker's counsel then submitted three supplements to his second sentencing memorandum on April 18, April 24, and May 24, 2017, while maintaining the original substance of his second sentencing memorandum. It seems clear from this timeline that Walker's counsel's objections covered the Government's additions.
Since Walker, in his Fifth Amendment argument, seeks only the same relief that we are granting him for the Government's breach of the plea agreement, we need not and do not consider the merits of his Fifth Amendment claim.
For two cases that illuminate what is meant by a defendant's "reasonable expectations," compare United States v. Riera ,
Indeed, the consciousness of the Government's choice is demonstrated by its treatment of the Section 2D1.1(b)(1) enhancement for possession of a weapon, which (unlike the other enhancements at issue here) the Government chose to include in Walker's original plea agreement. The Government now explains to us that the Section 2D1.1(b)(1) enhancement was based on similarly non-actionable information, and that at the time of the plea, Walker had a "credible argument" that it should not have applied. Appellee's Br. 53 n.8. Yet the Government chose to incorporate the Section 2D1.1(b)(1) enhancement in Walker's Pimentel estimate anyway-and, a fortiori , to exclude others. It is precisely that calculation that Walker consented to in his Pimentel estimate and that he could reasonably expect would be upheld by the Government.
