Evin Alexi Licona-Lopez appeals the denial by the District Court 1 of his motion for an evidentiary hearing on the government’s failure to move for a substantial-assistance departure under § 5K1.1 of the United States Sentencing Guidelines. Licona-Lopez participated in a controlled drug transaction and gave trial testimony which helped convict a co-conspirator. The government claimed it did not move for a substantial-assistance departure because Licona-Lopez withheld important information until trial and prejudiced the government’s case against the co-conspirator. Licona-Lopez argues that the refusal was in bad faith and based on an unconstitutional motive. We affirm.
I.
On October 17, 1997, Licona-Lopez was pulled over in Adelanto, California and 2,919.2 grams of methamphetamine were discovered in his vehicle. Licona-Lopez made a controlled delivery of the substance to Sergio Miranda Tafolla (“Miranda”) in Des Moines, Iowa. He was then indicted for conspiracy to distribute amphetamine.
Licona-Lopez pled guilty pursuant to a plea agreement which obligated him to cooperate fully with the government and provide truthful information at all times. The agreement gave the government “sole discretion” to file a motion for a substantial-assistance departure. Licona-Lopez participated in six police debriefings and testified against Miranda. At Miranda’s trial Licona-Lopez revealed for the first time that another person, “El Gordo,” helped arrange and carry out the drug transactions in which Licona-Lopez participated. Licona-Lopez admitted that he withheld information about El Gordo from police in order to protect himself and his family from retribution.
Licona-Lopez was sentenced on March 6, 1997. On the day before sentencing, the government informed Licona-Lopez that it would not move for a substantial-assistance departure. Licona-Lopez raised the issue at sentencing. The prosecutor acknowledged that Licona-Lopez’s trial testimony was truthful and helped secure Miranda’s conviction. She claimed, however, that Licona-Lopez “told a different story” each time he spoke to police and that the information about El Gordo tended to mitigate Miranda’s involvement in the conspiracy. The prosecutor stated she would consider moving for a substantial-assistance departure within a year if Licona-Lopez provided assistance that was substantial and helpful in ongoing investigations. The district court ruled that it was “up to the government” to decide whether to move for the departure, but directed the prosecutor to file the motion within a year or file a report within a year explaining the refusal to file the motion. Li-eona-Lopez was sentenced to 30 months of imprisonment.
On March 13,1997, a telephone conference was held among the district court, Licona-Lopez’s attorney, and the prosecutor. Lico-na-Lopez requested an evidentiary hearing on the government’s failure to move for a substantial-assistance departure. He offered to prove that his testimony at Miranda’s trial was truthful and played a significant role in obtaining Miranda’s conviction. He also stated that he would try to establish whether § 5K1.1 motions were filed under similar circumstances. The prosecutor stated that she refused to file the § 5K1.1 motion because Licona-Lopez had been untruthful during police debriefings. She claimed that the testimony of Licona-Lopez at Miranda’s trial was materially different from his statements in police debriefings and tended to mitigate Miranda’s involvement in the conspiracy. She also claimed that the discrepancies re *1042 quired the government to alter its trial strategy, gave impeachment material to the defense, and put the government in a defensive position. The district court denied the motion without prejudice. This appeal followed.
II.
Section 5K1.1 of the United States Sentencing Guidelines grants the district court the authority to depart from a guideline sentence “[u]pon motion of the government stating that the defendant has provided substantial assistance in the investigation or prosecution of another person who has committed an offense.” U.S. Sentencing Guidelines Manual § 5K1.1 (1997).
Licona-Lopez argues that the district court erred in denying his motion for an evidentiary hearing on the government’s refusal to file the motion because the refusal was in bad faith and unconstitutional. Lico-na-Lopez does not dispute that he violated his plea agreement by withholding information about El Gordo until Miranda’s trial. Rather, he argues that the refusal was improper because the assistance he rendered was substantial despite the fact that he was not completely truthful in police debriefings.
The district court generally lacks authority to award a substantial-assistance departure in the absence of a government motion.
See United States v. Matlock,
We hold that the district court correctly denied Licona-Lopez’s motion for an evidentiary hearing because Licona-Lopez did not make a threshold showing that the government’s refusal to file a substantial-assistance motion was improper. We agree that Licona-Lopez’s assistance was arguably substantial. The government acknowledged that his testimony at Miranda’s trial was truthful and the record supports Licona-Lo-pez’s claim that his testimony provided the crux of the case against Miranda. However, a claim that a defendant provided substantial assistance will not entitle the defendant to relief or an evidentiary hearing.
See Wade,
The government’s position is that it refused to file the motion because Licona-Lopez was untruthful with authorities in police debriefings and prejudiced the government’s case against Miranda. We cannot say that refusing to file the motion for these reasons was irrational. The government may refuse to file a substantial-assistance motion if the refusal is rationally related to a legitimate governmental end.
See Wade,
*1043
We find no evidence of bad faith or an unconstitutional motive in the record. The government did not make any promises or guarantees concerning the motion and the plea agreement left the motion to the “sole discretion” of the government.
Cf. Matlock,
Licona-Lopez argues that the refusal was unconstitutional because the prosecutor indicated a willingness to file the motion at a later time if Licona-Lopez provided substantial assistance in ongoing investigations. Li-cona-Lopez contends that postponing a motion regarding the defendant’s substantial assistance in order to secure post-sentencing cooperation violates due process.
Other courts have held that the government’s decision to defer making a § 5K1.1 motion on the premise that it will make a Federal Rule of Criminal Procedure 35(b) substantial assistance motion after sentencing may violate due process.

See, e.g., United States v. Martin,
The cases cited by Licona-Lopez hold that due process requires the government to determine at sentencing whether a defendant’s pre-sentencing cooperation merits a substantial-assistance departure and to move for the departure at sentencing if it decides in the affirmative.
See, e.g., Martin,
Licona-Lopez contends that
United States v. Pipes,
III.
For the reasons stated, the District Court’s denial of Licona-Lopez’s motion for an evidentiary hearing on the government’s refusal to move for a substantial-assistance departure is affirmed.

. The Honorable Charles R. Wolle, United States District Judge for the Southern District of Iowa.
. Fed.R.Crim.P. 35(b) allows the court to resen-tence the defendant to reflect substantial assistance rendered after sentencing while a § 5K1.1 motion reflects substantial assistance rendered before sentencing.
