Lesley Claywood Berry appeals pro se from the district court’s order denying several motions Berry filed concerning his request for reduction of sentence. See Fed. R.Crim.P. 35(b). We affirm.
Berry pleaded guilty to one count of conspiring to manufacture and distribute marijuana, see 21 U.S.C. § 841(a)(1) (1982), 21 U.S.C. § 841(b)(l)(A)(vii) (Supp. IV 1986), 21 U.S.C. § 846 (1982). The district court sentenced Berry to three years imprisonment. Berry then filed a series of motions seeking to reduce his sentence. After considering all of the grounds Berry raised in these motions, the district court denied Berry rule 35(b) relief.
On appeal, Berry renews some of the grounds he presented to the district court. These grounds are: (1) the court improperly considered the stalks of the marijuana plants in calculating the total quantity of *56 marijuana involved in Berry’s offense; (2) his counsel acted under a conflict of interest because he “was being paid by the attorneys representing one of [Berry’s co-defendants] whose interests ran counter to Berry’s;” and (3) his sentence was more severe than similarly situated coconspira-tors. In addition, Berry contends on appeal that his counsel was ineffective in not objecting to inaccurate information contained in the presentence investigation report (PSI). Finally, Berry contends the district court should have granted his postsentenc-ing motion for discovery regarding the disputed amount of marijuana. We reject each of Berry’s asserted grounds for relief.
First, we find meritless Berry’s contention concerning the court’s calculation of the quantity of marijuana. Although the statutory definition of marijuana specifically exempts the stalks, see 21 U.S.C. § 802(16) (Supp. IY 1986), the district court correctly noted the offense to which Berry pleaded guilty defines the illegal controlled substance as “1000 kilograms or more of a mixture or substance containing a detectable amount of marihuana,” id. § 841(b)(l)(A)(vii) (emphasis added). In view of this definition, the court did not commit error in sentencing Berry based on a quantity of marijuana that included the plants’ stalks.
Second, Berry’s conflict of interest claim requires him to “establish that an actual conflict of interest adversely affected his lawyer’s performance.”
Cuyler v. Sullivan,
Turning to Berry’s third claim, a disparity in sentences between coconspira-tors does not alone provide a basis for resentencing.
See United States v. Heisinger,
Consistent with our decision on Berry’s conflict of interest claim, the record also does not support a conclusion that Berry was prejudiced by his counsel’s failure, if any, to object to information in the PSI. Absent proof of prejudice, Berry’s ineffective assistance claim fails.
See Strickland v. Washington,
Accordingly, we affirm the district court’s order.
