The Sentencing Commission has only issued "advisory policy statements" applicable to revocations of probation and supervised release instead of mandatory guidelines. U.S.S.G. Ch. 7, Pts. A1, A3(a); see also United States v. George, 184 F.3d 1119, 1121 (9th Cir. 1999) ("Because the Commission has not yet issued guidelines relating to revocation of supervised release or changed its view that the Chapter 7 policy statements are merely advisory, we see no reason to reduce the flexibility of district courts in sentencing supervised release violators."). We have held that a district court, when revoking supervised release, has discretion to go outside the suggested sentencing range of the policy statements up to the statutory maximum listed in 18 U.S.C. S 3583(e)(3). See George, 184 F.3d at 1122-23 (finding no error where the district court considered the 7to 13-month range in the policy statements of Chapter 7, rejected it, and sentenced the defendant to 23 months imprisonment). The policy statement range for Musa's violation of the conditions of his supervised release is three to nine months, see U.S.S.G. S7B1.4, but the statutory maximum, as previously noted, is three years, see 18 U.S.C. S 3583(e)(3).
