In this case, we apply harmless error analysis to a claim made pursuant to
United States v. Booker,
543 U.S. -,
Timmy Davis pleaded guilty to possession of pseudoephedrine with intent to manufacture methamphetamine, a violation of 21 U.S.C: § 841(c)(1). - In his guilty plea, Davis did not admit to any specific drug quantity. At sentencing, the district court determined that 11.82 grams of pseu-doephedrine was attributable to Davis, and following the then-mandatory Federal Guidelines, assigned him a base level of twenty-six. The court reduced this to level twenty-three after giving him credit for acceptance of responsibility. The court computed Davis’s criminal history as category two, and noted that the guidelines recommended a range of 51-63 ■ months’ imprisonment for criminal history category two at offense level twenty-three. The Government made a motion for downward departure pursuant to U.S.S.G. § 5K1.1 because Davis cooperated with the Government, and his cooperation helped the Government obtain guilty pleas from other defendants. The sentencing court granted the motion, departed downward from the guidelines, and imposed a sentence of 38 months’ imprisonment.
While this case was pending on appeal, the Supreme Court decided
United States v. Booker,
543 U.S. -,
Davis’s sentence was enhanced, under a mandatory guidelines system, based on facts found by the judge and not admitted by him, and
Booker
indicates that was a violation of Davis’s Sixth Amendment right.
Id.
at 756. In the district court and in his initial brief on appeal, Davis argued that the court’s finding' with respect to drug quantity violated his constitutional rights according to the Supreme Court’s decision in
Blakely.
Davis therefore timely raised his constitutional objection. Accordingly, we review the constitutional issue
de novo,
and we will reverse and remand unless the Government can demonstrate that the- error was harmless beyond a reasonable doubt.
See United States v. Paz,
In
Paz,
we explained that harmless error analysis puts the burden on the Government to show “‘beyond a reasonable doubt that the error complained of did not contribute to the sentence obtained.’ ”
Id.
at 948 (quoting
United States v. Candelario,
In Davis’s case, the Government argues that the mandatory application of the guidelines was harmless because the Government requested, and the judge applied, a downward departure pursuant to U.S.S.G. § 5K1.1. U.S.S.G. § 5K1.1 is a provision of the guidelines that allows the court to depart from the guidelines based on the defendant’s assistance to authorities when the Government motions for such a departure. According to the Government, its § 5K1.1 motion gave the court “virtually unfettered discretion to impose a sentence outside the guidelines range.” The Government reasons that this discretion removed any Booker error, or rendered any Booker error harmless because the guidelines were not “mandatory” in this particular case.
We cannot conclude that the sentencing court’s grant of the § 5K1.1 motion either removed
Booker
.error or rendered it harmless beyond a reasonable doubt. The flaw in the Government’s argument is that the grant of § 5K1.1 did not give the sentencing court “unfettered” discretion, but rather, gave the court only limited discretion to consider the assistance that Davis rendered. This Court had previously stated, “When, on the Government’s motion, a district court grants a downward departure under U.S.S.G. § 5K1.1 ..., the sentence reduction may be based only on factors related to the defendant’s substantial assistance.”
United States v. Luiz,
We simply do not know what the sentencing court would have done had it understood the guidelines to be advisory rather than mandatory, and had properly considered the factors in 18 U.S.C. § 3553(a). Therefore, the Government
*1272
cannot meet its burden of showing that the mandatory application of the guidelines in violation of Davis’s Sixth Amendment right was harmless beyond a reasonable doubt.
Cf. Rodriguez,
Accordingly, we REVERSE and REMAND for re-sentencing consistent with Booker.
Notes
. The Government’s brief emphasizes that Davis’s plea agreement acknowledged "whether or not the sentencing court decides to depart downward below a guideline range or statutory minimum sentence, or reduce the defendant's sentence, as well as the extent of any such downward departure or reduction, is completely within the sentencing court’s discretion.” This is simply an acknowledgment of the sentencing court's limited discretion to depart downward on the basis of Davis’s assistance.
