MEMORANDUM**


2
The United States appeals the 106-month sentence imposed on Ramon Bonillo-Castro, following his guilty plea, for conspiracy to distribute heroin in violation of 21 U.S.C. §§ 841(a)(1) and 846, and use of a firearm during a drug trafficking crime in violation of 18 U.S.C. § 924(c)(1).   The government contends that the district court erred by imposing a sentence below the statutorily-mandated minimum.   We have jurisdiction under 28 U.S.C. § 1291, and we vacate and remand.


3
We review de novo a district court's decision to depart below the statutorily-mandated minimum sentence.   United States v. Vilchez, 967 F.2d 1351, 1353 (9th Cir.1992).


4
Under the Guidelines, if "a statutorily required minimum sentence is greater than the maximum of the applicable guideline range, the statutorily required minimum sentence shall be the guideline sentence."   U.S.S.G. § 5G1.1(b);   see also United States v. Sharp, 883 F.2d 829, 831 (9th Cir.1989).   A district court may only depart below the mandatory minimum upon a motion of the government reflecting the " 'defendant's substantial assistance in the investigation or prosecution of another person who has committed an offense.' "   Vilchez, 967 F.2d at 1355 (quoting 18 U.S.C. § 3553(e)).   In limited circumstances, the district court may depart in the absence of a government motion if the government's failure to make the motion was unconstitutionally motivated or not rationally related to any legitimate state objective.   Wade v. United States, 112 S.Ct. 1840, 1843-44 (1992).


5
Here, Bonillo-Castro pled guilty to conspiracy to distribute 560 grams of heroin in violation of 21 U.S.C. §§ 841(a)(1) and 846, and use of a firearm during a drug trafficking crime in violation of 18 U.S.C. § 924(c)(1).   Although Bonillo-Castro's applicable sentencing range was 46 to 57 months, the statute mandates a sentence of 60 months.   See 21 U.S.C. § 841(b)(1)(B)(i).   Additionally, section 924(c)(1) required a consecutive 60-month sentence to any other term of imprisonment.


6
At sentencing, the district court imposed a 46-month sentence for the drug offense, followed by a consecutive 60-month sentence for the firearm offense.   The court indicated that the 46-month sentence was "in keeping with the minimum mandatory purpose of the statute" because Bonillo-Castro was already serving a consecutive 60-month sentence for the firearm offense.   The government contends that the district erred by failing to impose the mandatory 60-month sentence required by statute for the drug offense.   We agree.


7
The government did not make a motion for substantial assistance.   The record is devoid of any evidence that the government's decision was irrational or based upon an unconstitutional motive.   In the absence of a government motion, the district court lacked the authority to disregard the mandatory 60-month sentence applicable to the drug offense.   See Vilchez, 967 F.2d at 1356.


8
Accordingly, we vacate Bonillo-Castro's sentence and remand the case for resentencing consistent with this memorandum disposition.


9
VACATED AND REMANDED.
