This case returns after a remand to the district court for resentencing. In
United States v. Pepper,
I. BACKGROUND
Pepper pled guilty to conspiracy to distribute more than 500 grams of methamphetamine, in violation of 21 U.S.C. §§ 841(a)(1), (b)(1)(A), and 846. Pepper’s total offense level of 30 and criminal history category I produced an advisory United States Sentencing Guidelines range of 97 to 121 months. Pepper was eligible for safety-valve relief, thus the statutory mandatory minimum sentence of 120 months’ imprisonment did not apply.
See
18 U.S.C. § 3553(f), U.S.S.G. §§ 2D 1.1(b)(6), and 5 C 1.2. In Pepper’s initial sentencing, the government filed a motion for substantial assistance, pursuant to U.S.S.G. § 5K1.1, and recommended a 15% downward departure. The district court departed downward 75% and sentenced Pepper to 24 months’ imprisonment. We reversed, finding the district court erred by considering factors unrelated to Pepper’s assistance in granting the § 5K1.1 downward departure motion, and we remanded, concluding “given the pedestrian nature of Mr. Pepper’s assistance, it is far from certain that the court would have arrived at the same guidelines sentence had it considered only assistance-related elements when deciding the extent of the departure.”
Pepper I,
On remand, the district court found Pepper’s assistance merited a 40% downward departure, which reduced the bottom of the advisory sentencing Guidelines range to 58 months. Then, under 18 U.S.C. § 3553(a), the district court granted a downward variance of 59%, based on Pepper’s post-sentencing rehabilitation, lack of “violent” history, and, to a lesser degree, on the need to avoid unwarranted sentencing disparity among co-defendants. The district court again imposed a sentence of 24 months’ imprisonment. This appeal followed.
*411 II. DISCUSSION
A. Substantial Assistance Departure
The government argues the district court abused its discretion by granting a 40% downward departure given the pedestrian nature of Pepper’s assistance. We review for abuse of discretion the extent of a reduction for substantial assistance.
United States v. Coyle,
At the resentencing hearing, the government described Pepper’s assistance, which included debriefing with law enforcement immediately after his arrest, a proffer interview, and testifying before the grand jury against two defendants. The government acknowledged Pepper was the main witness against one of the two defendants.
Although there is no bright line percentage or mathematical formula to determine when the extent of a substantial assistance departure becomes unreasonable,
see, e.g., United States v. Haack,
B. Downward Variance
The government next argues the district court abused its discretion in granting a 59% variance. “We review a district court’s interpretation and application of the guidelines de novo, its factual findings for clear error, and any decision to depart from the appropriate guidelines range for abuse of discretion.”
United States v. Judon,
*412 The district court’s § 5K1.1 downward departure brought the bottom of the Guidelines range to 58 months. Thereafter, the district court stated, “I am going to do a variance down to 24 months” and noted the significance of varying from 58 months to 24 months.
In considering evidence in the record to support the variance, the district court first mentioned Pepper had “no history of violence.” The district court tried to distinguish Pepper’s lack of violent history from Pepper’s lack of a criminal history, stating “you could have a history of violence in your record ... and have a criminal history or not have a criminal history.” This vague distinction is unpersuasive. The district court did not substantiate what it meant by “no history of violence.” Indeed, if Pepper had a violent
criminal
history, he would have been ineligible for safety-valve relief, subject to the 120-month statutory mandatory minimum, and the possibility of an enhancement or an upward departure. To the extent the district court considered the absence of violence in Pepper’s life generally, we have previously held “[t]he absence of grounds that justify further punishment is not a ground for a downward variance.”
United States v. Feemster,
The district court next considered unwarranted sentencing disparity among coconspirators:
1
Alexander Blankenship (Blankenship) sentenced to 72 months’ imprisonment, Felipe Sandoval (Sandoval) sentenced to 35 months’ imprisonment, and Jose Martin Barragan-Torres (Barragan-Torres) sentenced to 90 months’ imprisonment. To the extent unwarranted sentencing disparities among coconspira-tors and co-defendants are a proper consideration under 18 U.S.C. § 3553(a)(6),
2
see United States v. Lazenby,
Finally, the district court questioned Pepper regarding his post-sentence conduct. Pepper testified about his community college attendance, work record, sobriety, and compliance with the other conditions of his supervised release. In granting the downward variance the district court acknowledged, “I don’t know whether or not it’s appropriate to consider the release — the year he’s been out now, almost a year, how well he’s done.” Nonetheless, the district court concluded, “I’m not going to be disingenuous and say that I haven’t considered [Pepper]’s post-release conduct because I have considered it. Exactly how much weight I’m giving it, I don’t know exactly.”
Our court recently considered the relevance of post-sentence rehabilitation,
see United States v. Jenners,
The lack of clarity regarding the extent to which the district court relied on any one factor notwithstanding, we conclude the district court abused its discretion in granting the downward variance. The district court failed to balance the other factors in § 3553(a), such as the need to impose a sentence reflecting the seriousness of Pepper’s offense, which involved between 1,500 and 5,000 grams of methamphetamine mixture and ten to fifteen people, or how, in this case, a sentence of 24 months would promote respect for the law. The district court impermissibly considered Pepper’s post-sentence rehabilitation, and further erred by considering Pepper’s lack of violent history, which history had already been accounted for in the sentencing Guidelines calculation, and by considering sentencing disparity among Pepper’s co-defendants without adequate foundation and explanation.
III. CONCLUSION
For the reasons stated, we reverse and remand this case for resentencing consistent with this opinion. The district court expressed a reluctance to resentence Pepper again should this case be remanded. Thus, we remand Pepper’s case for re-sentencing by a different judge, pursuant to our authority under 28 U.S.C. § 2106.
See United States v. Rogers,
Notes
. The district court indicated its consideration of unwarranted sentencing disparity among the co-defendants was not a primary factor in granting a downward variance.
. We note " § 3553(a)(6) may more appropriately apply to disparities on a national level and not within the same conspiracy,” but we continue to follow our own precedent.
