UNITED STATES OF AMERICA, Plaintiff-Appellee,v.TAMMY MOODY, also known as Tammy Hope, Defendant-Appellant.
No. 00-51242
UNITED STATES COURT OF APPEALS FOR THE FIFTH CIRCUIT
December 21, 2001

Joseph H Gay, Jr., Assistant US Attorney, Margaret Feuille Leachman, (argued), San Antonio, TX, for Plaintiff-Appellee.
M Carolyn Fuentes, (argued), San Antonio, TX, for Defendant-Appelant.
Appeal from the United States District Court For the Western District of Texas. SA-95-CR-296-ALL. Orlando L Garcia, US District Judge.
Before BALDOCK*, SMITH and EMILIO M. GARZA, Circuit Judges.
EMILIO M. GARZA, Circuit Judge:


1
Tammy Moody ("Moody") appeals her four-year supervised release term imposed by the district court upon revocation of her original term of supervised release. We hold that the district court properly imposed the four-year term under 18 U.S.C.  3583(h).


2
Moody pleaded guilty to possession with intent to distribute 142 grams of methamphetamine in violation of 21 U.S.C.  841(a)(1). The government sought an enhanced penalty under  841(b)(1)(B) based on evidence establishing drug quantity. The district court sentenced Moody to forty-five months' imprisonment1, to be followed by five years' supervised release. Moody served her prison sentence, and began her supervised release. Thereafter, the government moved to revoke her supervised release for violations of the terms of her release. After Moody pleaded true to the alleged violations, the district court    revoked her supervised release, and imposed a nine-month imprisonment term, to be followed by a new term of four years' supervised release. Moody now appeals.


3
We will uphold a sentence after revocation of supervised release "'unless it is in violation of law or is plainly unreasonable.'" United States v. Stiefel, 207 F.3d 256, 259 (5th Cir. 2000) (quoting United States v. Mathena, 23 F.3d 87, 89 (5th Cir. 1994)).    Section 3583(h) authorizes a court, upon revocation of a defendant's supervised release, to impose a new term of supervised release to follow a term of imprisonment. Section 3583(h), however, limits the duration of supervised release a court can impose:


4
The length of such a term of supervised release shall not      exceed the term of supervised release authorized by      statute for the offense that resulted in the original term of      supervised release, less any term of imprisonment that      was imposed upon revocation of supervised release.


5
18 U.S.C.  3583(h). The issue in this case is whether the district court imposed a term of supervised release on Moody in excess of that permitted by  3583(h). Specifically, we are asked to determine which statute, in addition to  841(a)(1), governed the offense that resulted in Moody's original term of supervised release.


6
Moody contends that the relevant statute for her offense was 21 U.S.C.  841(b)(1)(C), which authorizes no more than three years' supervised release. To support her claim, she relies on our decision in United States v. Doggett, 230 F.3d 160 (5th Cir. 2000),    cert. denied 148 L. Ed. 2d 1014, 121 S. Ct. 1152 (2001). In Doggett, we held that drug quantities set forth in  841(b) must be alleged in an indictment to trigger the escalating penalties associated with those quantities. Id. at 164-65. As a result, we held that defendants charged with unspecified drug quantities could only be sentenced using  841(b)(1)(C). Because  841(b)(1)(C) authorizes no more than three years' supervised release, Moody argues that her four-year term imposed by the district court must be vacated.


7
We find Moody's argument to be unavailing. Though Moody is correct that a defendant convicted today of possession of a drug quantity not specified in the indictment would be sentenced under  841(b)(1)(C), that was not the state of the law at the time Moody was convicted and sentenced. Moody has never challenged the language of her indictment or the drug quantity used in calculating her original sentence, either by direct appeal or collateral review. She may not now use her new term of supervised release as a vehicle to do so. The only issue here is whether the district court looked to the proper statute to determine the maximum    length of her new supervised release term. The plain language of  3583(h) directs courts to look to the "statute for the offense that resulted in the original term of supervised release."  3583(h) (emphasis added). At the time Moody was convicted, the district court sentenced her under  841(b)(1)(B). See  841(b)(1)(B) (authorizing supervised release term of "at least four years" for  841(a) violations involving certain drug quantities). The court determined Moody's guideline range to be four to five years, and ultimately sentenced her to five years. Thus, the maximum term of supervised release the district court could have imposed on Moody under  3583(h) was five years less the nine months of incarceration, or four years and three months.


8
AFFIRMED.

1
 Although the mandatory minimum term of imprisonment under  841(b)(1)(B) is five years, the district court imposed a shorter term in response to the government's motion stating that Moody provided "substantial assistance in the investigation or prosecution of another person who has committed an offense." See 18 U.S.C.  3553(e) (authorizing court to impose a sentence below the statutory minimum based on substantial assistance); U.S. Sentencing Guidelines Manual  5K1.1 (stating factors a court may consider in determining the length of a reduction based on substantial assistance).
