Pursuаnt to a plea agreement, Stanley Johnson pled guilty to conspiracy to distribute methamphetamine and cocaine, and possession of a firearm during a drug trafficking crime. The agreement obligated the government to file a downward departure motion upon its determination that Johnson had provided it with substantial assistance. The government did not move for downward departure and Johnson was sentenced to 324 months imprisonment on the distribution count and 60 months on the firearm count, to be served consecutively, followed by supervised release. Johnson appeals his sentence. Because we find that the prosecution failed to comply with the plea agreement, we vacate the sentence and remand to the district court for resentencing.
I. BACKGROUND
The plea agreement between Johnson and the government stated:
Should you fully comply with all the terms and conditions of this agreement, and if you continue to do so in your dealings with the Probation Officer, and the United States Attorney for the Dis *1051 trict of Nebraska concludes that you have provided substantial assistance in the investigation or рrosecution of one or more other persons who have committed an offense, the United States shall file a motion with the sentencing Court requesting the Court to depart downward from the sentencing guidelines in its sentencing of you.
Clerk’s Record at 18 (emphasis added). The agreement further provided that the motion could be made pursuant to 18 U.S.C. § 3553(e) or Unitеd States Sentencing Guidelines § 5K1.1 or both. The pre-sentence investigation report also refers to the plea agreement, stating, “In exchange for the defendant’s pleas and cooperation, the government agreed to file a motion for downward departure pursuant to United States Sentencing Guidelines (U.S.S.G.) § 5K1.1 and/or 18 U.S.C. 3553(e) should the defеndant’s cooperation be deemed substantial.”
At the July 16, 1999, sentencing, counsel for Johnson stated:
I would like to bring to the Court’s attention a couple of facts. First of all, since Mr. Johnson’s incarceration, he has done everything he can to cooperate with the Government. He has had a number of meetings with some law enforcement officials, I think at least three or four, maybe even possibly another one, and I know that he has already provided a substantial assistance and his cooperation is not done. He intends to continue cooperating in the investigation of a very large number of individuals. I would just like to bring that to the Court’s attention.
Sent. Tr. at 9. The district court halted defense counsel at that point.
The Assistant United States Attorney did not make a departure motion. However, at the sentencing hearing, she indicated that she had in her possession a motion for reduction of sentence, pursuant to Federal Rule of Criminal Procedure 35(b), and that she would ask leave to file it at the end of the hearing. At the close of the procedure, the government asked leave to file the Rule 35(b) motion, which the court granted. In its motion, filed immediately after the hearing, the government conceded Johnson’s substantial assistance, stating:
[Pjursuant to Rule 35(b) of the Rules of Criminal Procedure [the government moves the] Court to lower the sentence of the defendant imposed on July 16, 1999, due to Defendant’s substantial assistance to the government.
It is expected that Mr. Johnson may be needed for further testimony and the government will file a request for a hearing on this Motion upon completion of his cooperation.
Add. at 14A (emphasis added). To date, the government has not filed a departure motion under section 5K1.1 оf the United States Sentencing Guidelines or 18 U.S.C. § 3553(e), and Johnson’s sentence imposed on July 16,1999, remains in force.
II. DISCUSSION
A. Reviewability
As a preliminary matter, the government argues that its “refusal to file a substantial assistance motion is reviewable only when the defendant makes a substantial threshold showing that the refusal was irrational or based on an unconstitutional motive.” The argumеnt is misplaced. We would agree with the government if Johnson were challenging the government’s exercise of discretion as to whether he had provided substantial assistance, which under the plea agreement the government had reserved to itself,
United States v. Wilkerson,
A prosecutor’s agreement that, in any significant degree, induces the defendant to enter a plea, creates a duty to satisfy obligations that have arisen under that agreement.
Santobello v. New York,
The government further argues that we cannot address issues surrounding the plea agreement because Johnson “failed to object at the time of sentencing to the Government’s decision not to file a motion for downward departure,” and, therefore, such issues were not raised and decided at the district court level. Relying on
Hormel v. Helvering,
B. The Plea Agreement
Issues concerning the interpretation and enforcement of a plea agreement are issues of law, which we review de novo.
Van Thournout,
Resolution of the plea-agreement issue in this matter requires us to look at thе timing of a defendant’s substantial assistance. In 1998, Rule 35(b) was amended to provide that “[i]n evaluating whether substantial assistance has been rendered, the court may consider the defendant’s pre-sentence assistance.” Fed.R.Crim.P. 35(b). Before the amendment was added, a defendant could benefit by providing substantial assistance prior to sentencing, рursuant to section 5K1.1 of the guidelines, and could benefit by providing substantial assistance after sentencing, pursuant to Rule 35(b). However, no formal mechanism considered both a defendant’s pre- and post-sentencing assistance in determining whether, in the aggregate, he had provided the substantial assistance required for a reduction of sentenсe.
Id.
advisory committee note. Therefore, it was unclear whether he could benefit from pre-sentencing assistance that, standing alone, did not amount to substantial assistance, but when added to post-sentencing assistance, would constitute substantial assistance.
See, e.g., United States v. Alvarez,
We recognize that, in the plea agreement, the government retained the “sole discretion” to determine whether Johnson’s assistance was substantial, which, of course, is permissible.
Wilkerson,
Once the government determined that Johnson had provided substantial assistance, it was obligated to follow through with its agreement to file a deрarture motion.
Santobello,
Although, typically, a trial court may not depart from the Sentencing Guidelines without a motion by the government,. the defendant may “nevertheless have a remedy for the government’s refusal to file thе motion if the plea agreement] between the [defendant] and the government bound the government to file such a motion.”
Coleman,
In the present case, the language of the plea agreement is clear and the government’s failure to file a departure motion prior to sentencing — when it hаd already determined that Johnson had provided substantial assistance — breached that agreement.
Cf. id.
at 668 (suggesting that the government may have violated its plea agreement in failing to file a section 3553(e) motion and remanding for an evi-dentiary hearing on the issue). The 1998 amendment to Rule 35(b) is not a mechanism to string a defendant along once thе government has concluded he has already satisfied his obligation under a plea agreement-indefinitely holding a departure motion over his head like Damocles’ sword.
See
Fed.R.Crim.P. 35(b) advisory committee note (discussing the purpose of the amendment);
United States v. Novak,
We acknowledge the legitimacy of the government’s goal of encouraging a defendant’s further cooperation. However, once the government determines that a defendant has satisfied a condition precedent, the government’s fulfillment of its own obligation under the plea agreement becomes paramount.
Santobello,
C. Rule 35(b)
Johnson also asks us to determine whether a Rule 35(b) motion provides the same relief as that provided by a section 3553(e) or 5K1.1 motion. Because we remand for resentencing consistent with the terms of the plea agreement, which requires the govеrnment to file a section 3553(e) and/or a 5K1.1 motion, we need not reach this issue. 3
*1055 III. CONCLUSION
Unlike the situation in
Rounsavall,
The plea agreement, along with the government’s exercise of its discretion to determine Johnson’s substantial assistance, required the government to file a section 5K1.1 or a 3553(e) departure motion, or both, prior to sentencing. The government breached the agreement by fading to do so. Consequently, we vacate the sentence and remand the case to the district court for resentencing. Because Johnson is entitled to specific performance of the plea agreement, upon remand, the government is to file a motion or motions in accordance with the plea agreement. 5
Notes
. In any event, where a defendant fails to raise a breach of plea agreement in the district court, or even before this court, we have the authority to review the issue for plain error when the defendant's substantial rights are affected.
Granados,
The present case is unlike
United States v. Oransky,
. The government attempts to distract us from this acknowledgment by directing оur attention to its references to "the extent of [Johnson’s] cooperation ... not [being] known at [that] time." The government challenges the boundaries of our imaginations when it asks us to accept the premise that it did not know the extent of Johnson's cooperation during sentencing but suddenly had an epiphany later that day-an epiphany that was apparently already emerging prior to sentencing.
. The government argues that a Rule 35(b) motion would yield Johnson essentially the
*1055
same result as would a section 3553(e) or 5K1.1 motion. Whether or not the government is correct, its argument further bolsters our position. If it had determined a Rule 35(b) motion-which it believes to be the equivalent of a section 3553(e) or 5K1.1 motion-was in order prior to sentencing, it should have filed the appropriate departure motion at that time. "[A]t this stage the prosecution is not in a good position to argue that its ... breach of agreement is immaterial.”
Santobello,
Also, we note in passing that appeal of a reduced sentence pursuant to a Rule 35(b) motiоn carries a greater onus than does a pre-sentence departure.
See United States v. Coppedge,
. We realize that, in the future, the government may try to avoid the result of our decision today by simply not acknowledging that it has already determined that a defendant's assistance has been substantial. It is our hope that the aegis of Rounsavall and prosecutors’ integrity will deter that course.
. Any additional post-sentencing substantial assistance can be considered pursuant to a Rule 35(b) motion.
