This panel has determined unanimously that oral argument would not *

materially assist the determination of this appeal. See Fed. R. App. P. 34(a)(2);

10th Cir. R. 34.1(G). The case is therefore ordered submitted without oral

argument. This order and judgment is not binding precedent, except under the

doctrines of law of the case, res judicata, and collateral estoppel. It may be cited,

however, for its persuasive value consistent with Fed. R. App. P. 32.1 and

10th Cir. R. 32.1.

UNITED STATES COURT OF APPEALS

FOR THE TENTH CIRCUIT

UNITED STATES OF AMERICA,

 Plaintiff-Appellee,

 v.

DIANE C. CHRISTENSEN,

 Defendant-Appellant.

No. 06-4277

(D.C. No. 2:04-CR-40-DS)

(D. Utah)

ORDER AND JUDGMENT

*

Before TYMKOVICH, EBEL, and GORSUCH, Circuit Judges.

Defendant Diane C. Christensen pleaded guilty to conspiracy to impede,

impair, obstruct, and defeat the lawful government functions of the Internal

Revenue Service in violation of 18 U.S.C. § 371. Her plea agreement states that

she “knowingly, voluntarily and expressly waive[s] [her] right to appeal any

sentence imposed . . . and the manner in which the sentence is determined, on any
-2-

of the grounds set forth in [18 U.S.C. § 3742] or on any ground whatever, except

. . . [for] (1) a sentence above the maximum penalty provided in the statutes of

conviction as set forth in [the plea agreement]; and (2) a sentence above the highend of the guideline range as determined by the district court at 

sentencing . . . .” Motion to Enforce, Attachment A (Plea Agreement) at 3. The

district court determined a guideline range of 41 to 51 months and imposed a

sentence of 41 months, well within the five-year statutory maximum recited in the

plea agreement and at the low-end of the guideline range. Nonetheless, defendant

appealed. The government has now moved to enforce defendant’s appeal waiver

under United States v. Hahn, 359 F.3d 1315 (10th Cir. 2004) (en banc). We grant

the motion and dismiss the appeal. 

Under Hahn, we consider “(1) whether the disputed appeal falls within the

scope of the waiver of appellate rights; (2) whether the defendant knowingly and

voluntarily waived his appellate rights; and (3) whether enforcing the waiver

would result in a miscarriage of justice.” Id. at 1325. Defendant contends that

her appeal does not fall within the terms of the appeal waiver she accepted, and

that her waiver of appeal rights was not knowingly and voluntarily entered

because she did not waive the right to appeal an illegal sentence. She claims that

her sentence is illegal under Blakely v. Washington, 542 U.S. 296 (2004), and

United States v. Booker, 543 U.S. 220 (2005), because the district court may have

enhanced her sentence based on facts not found by a jury.
-3-

Defendant’s argument is patently without merit. A sentence is illegal if it

“is ambiguous with respect to the time and manner in which it is to be served, is

internally contradictory, omits a term required to be imposed by statute, is

uncertain as to the substance of the sentence, or is a sentence which the judgment

of conviction did not authorize.” United States v. Dougherty, 106 F.3d 1514,

1515 (10th Cir. 1997) (quotation omitted); see also United States v.

Gonzalez-Huerta, 403 F.3d 727, 739 n.10 (10th Cir.) (holding term “illegal

sentence” is reserved for instances where sentence exceeds statutory maximum),

cert. denied, 126 S.Ct. 495 (2005). Defendant does not argue, nor do any of the

materials submitted to us suggest, that her sentence is deficient in any such

fundamental respect. 

Moreover, as noted, defendant expressly agreed to waive her right to appeal

“the manner in which the sentence is determined, . . . , except . . . [for] (1) a

sentence above the maximum penalty provided in the statute of conviction . . . ,

and (2) a sentence above the high-end of the guideline range as determined by the

district court at sentencing.” Plea Agreement at 3. Defendant’s sentence is

within the statutory maximum and at the low-end of the guideline range. The plea

colloquy demonstrates that defendant knowingly and voluntarily agreed to this

appeal waiver. Thus, the sentence imposed complies with the terms of the plea

agreement and the understanding expressed by the defendant at the plea hearing. 
-4-

Defendant has not demonstrated that her appeal falls outside the scope of waiver

or that she did not knowingly and voluntarily agree to the appeal waiver. 

Accordingly, the government’s motion to enforce the waiver is GRANTED

and the appeal is DISMISSED. The mandate shall issue forthwith.
