Before MCMILLIAN, LAY, and MURPHY, Circuit Judges.
                            ___________


LAY, Circuit Judge.

       Derek Doucette Vernon pled guilty to a one count information charging him with
conspiracy to possess with intent to distribute either cocaine powder or cocaine base
in violation of 21 U.S.C. §§ 841(a)(1) and 846. The plea agreement provided that the
government would move for a downward departure if the United States Attorney
decided that Vernon had provided “substantial assistance” pursuant to United States
Sentencing Guidelines § 5K1.1 and 18 U.S.C. § 3553(e).1 The government filed a
downward departure motion for substantial assistance under U.S.S.G. § 5K1.1,2 but not
pursuant to 18 U.S.C. § 3553(e).3 Vernon moved the district court to compel the
government to file the downward departure motion under the statute. The district court
denied the motion to compel and sentenced Vernon to 120 months imprisonment, the
statutory minimum. Vernon appeals, claiming that the district court erred in failing to

      1
          The substantial assistance section of the plea agreement provided:

      Should Defendant fully comply with all the terms and conditions of this
      agreement and the United States Attorney concludes he has provided
      substantial assistance in the investigation or prosecution 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 from
      the sentencing guidelines in its sentencing. Such motion may be made
      pursuant to Title 18, United States Code, Section 3553(e) and Section
      5K1.1 of the United States Sentencing Commission Guidelines.
      2
          The relevant language under U.S.S.G § 5K1.1 provides:

      Substantial Assistance to Authorities (policy statement)

      Upon 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, the court may depart from the guidelines.
      3
          The full text of 18 U.S.C. § 3553(e) is as follows:

      Limited authority to impose a sentence below a statutory minimum.
      – Upon motion of the Government, the court shall have the authority to
      impose a sentence below a level established by statute as minimum
      sentence so as to reflect a defendant’s substantial assistance in the
      investigation or prosecution of another person who has committed an
      offense. Such sentence shall be imposed in accordance with the
      guidelines and policy statements issued by the Sentencing Commission
      pursuant to section 994 of title 28, United States Code.

compel the government to file a motion for downward departure under 18 U.S.C. §
3553(e) and in its analysis of relevant conduct under U.S.S.G. § 1B1.3(a)(1)(B). We
affirm.

Downward Departure
       There is no doubt that Vernon furnished considerable assistance to the
government as evidenced by the affidavits of Leon Milton and Jeffrey Mitchell, two of
Vernon’s co-defendants. In their affidavits, Milton and Mitchell stated that they pled
guilty “as a direct result of Mr. Vernon’s agreement” to testify against them at trial and
admitted that without Vernon’s plea agreement they would not have entered guilty
pleas. Milton Aff. ¶ 4; Mitchell Aff. ¶ 4. The government does not challenge this fact
and recognized it by filing a motion for downward departure under U.S.S.G. § 5K1.1.
Vernon contends, however, that the district court erred in failing to compel the
government to file a motion for downward departure under 18 U.S.C. § 3553(e).4 We
disagree.




      4
        Vernon also claims that the district court utilized the wrong burden of proof in
denying the motion to compel the government to file a motion for downward departure
pursuant to § 3553(e). In an order dated March 4, 1998, the district court stated that
the burden of persuasion for the motion to compel was on the defendant. United States
v. Vernon, No. 8: CR96-00046 (D. Neb. May 4, 1998) (order scheduling sentencing
hearing). It is true that the burden of production shifts to the government to show that
they did not have an impermissible or unconstitutional motive after the defendant makes
a substantial threshold showing that the government acted unconstitutionally or
irrationally. See United States v. Stockdall, 

, 1261 (8th Cir. 1995)
(“Because the separation of powers concerns underlying this issue are important, we
will remand the case to permit the government either to file new § 3553(e) motions or
to provide satisfactory assurance to the district court that its prior motions were based
solely upon its evaluation of the [defendants’] respective substantial assistance.”). The
burden of persuasion, however, remains with the defendant.

                                           -3-
       Ordinarily, the government must move for a downward departure for substantial
assistance before the district court can depart on that basis. See United States v.
Stockdall, 

, 1259 (8th Cir. 1995). There are, however, exceptions to this
rule. This court has recognized “that relief may be granted absent a government
substantial assistance motion if a defendant shows that the government’s refusal to
make the motion was based on an unconstitutional motive, that the refusal was
irrational, or that the motion was withheld in bad faith.” United States v. Kelly, 

, 617-18 (8th Cir. 1994) (citing Wade v. United States, 

, 185-86
(1992)). See also United States v. Rounsavall, 

, 667-68 (8th Cir. 1997)
(holding that “[a] defendant is entitled to an evidentiary hearing to determine whether
the government acted improperly if she is able to make a substantial threshold showing
that the government acted irrationally, in bad faith, or in violation of one’s
constitutional rights”) (citation omitted). Vernon contends that this exception applies
to him. Specifically, he argues that it was improper for the government to base its
decision not to seek relief under the statute on the fact that he did not testify at the
sentencing hearing.

       We find that Vernon did not make a substantial threshold showing that the
government acted unconstitutionally, irrationally, or in bad faith. His plea agreement
with the government did not entitle him to refuse to testify in the sentencing
proceedings. In fact, the plea agreement specifically provided, “Defendant shall
truthfully testify, if subpoenaed, before the Grand Jury and/or at any trial or other court
proceeding regarding any matters about which the United States Attorney’s Office may
request his testimony.” Vernon may have been entitled to assert the privilege against
self-incrimination in response to particular questions if he had testified in the sentencing
hearings, but given his promise to testify against his co-defendants at any type of




                                            -4-
proceeding, he was not entitled to assert a blanket privilege and refuse to take the stand
at the sentencing hearing.5

       Vernon’s reservation in the plea agreement that he could contest the amount and
the type of the drugs at sentencing does not change this outcome.6 The transcript of the
co-defendants’ sentencing hearing included testimony about issues other than the
weight and the identity of the drugs; it also involved evidence of the co-defendants’
activities and relationships with one another, all of which would have been relevant to
sentencing. The reservation Vernon made in his plea agreement would not have
covered the latter testimony, and therefore, the government legitimately considered his
refusal to adhere to the terms of his agreement and testify against his co-defendants “at
any trial or other court proceeding” in assessing the quality of his assistance.

       Furthermore, Vernon gave the government the discretion in the plea agreement
to evaluate whether the level of his assistance merited a statutory departure. It is well-
settled in this circuit that the government is not required to file a statutory departure
motion every time it files for a downward departure from the guidelines. See e.g.,
United States v. Polanco, 

, 896 (8th Cir. 1995). Vernon failed to make a
threshold showing that the government acted unconstitutionally in refusing to move for



      5
        While the prosecution cannot call defendants to the stand during their own trials,
in other circumstances the Fifth Amendment privilege must be invoked in response to
specific questions or requested documents. See, e.g., In re Matter of Grand Jury
Subpoena, 

, 1359-60 (8th Cir. 1984) (grand jury testimony); United
States v. Dick, 

, 1119 (8th Cir. 1982) (IRS case); see also United States
v. Argomaniz, 

, 1356 (11th Cir. 1991) (noting “blanket refusal to
produce records or to testify will not support a fifth amendment claim”).
      6
       This portion of the plea agreement provides: “The parties acknowledge the
amount and the type of controlled substance involved in this conspiracy is a
determination to be made by the District Court at the time of Defendant’s sentencing.”

                                           -5-
a downward departure under § 3553(e). The court may therefore not second-guess the
government’s determination that he failed to substantially assist it.

Relevant Conduct
        In an order dated May 4, 1998, the district court calculated a base offense level
of thirty-two based on the quantity of drugs with which Vernon was involved.7 In so
doing, the court considered two separate incidents. Vernon appeals the district court’s
consideration of one incident which occurred in January 1996, claiming there was
insufficient proof that he was involved in the drug transaction that occurred on that
date.

        Notwithstanding the district court’s consideration of these incidents as relevant
conduct, the defendant pled guilty in the Rule 11 proceeding to conspiracy to possess
with intent to distribute cocaine “in an amount exceeding 500 grams” or “50 grams or
more” of cocaine base. Fifty grams of cocaine base results in a base offense level of
thirty-two, which was the base offense level utilized by the district court. The court did
not use Vernon’s relevant conduct to increase Vernon’s sentence beyond the base level
to which he pled guilty. Therefore, any error that may have occurred in determining
Vernon’s relevant conduct was harmless.

                                    CONCLUSION

      For the foregoing reasons, the judgment of the district court is affirmed.




      7
       This base offense level was reduced from 36, which was used to calculate
Vernon’s sentence in an earlier court order. The prior offense level was based on
testimony from Kelvin Jameson which was later determined to be unreliable.
