On August 19, 2002, Aрpellant entered into a plea agreement on a charge of unlawful reentry into the United States after having been previously convicted of a felоny, in violation of 8 U.S.C. § 1326(a)(1) and (2) and 8 U.S.C. § 1326(b)(1). The plea agreement provided that “the defendant knowingly waives the right to appeal any sentence within the guideline range ... as determined by the Court after resolution of any objections by either party to the presentence report....” Ree., Yol. I, at 5. Despite this waiver, Appellant now appeals the district court’s ruling that certain misdemeanor convictions (in which the record is silent on whether Appellant was represented) are included in his criminal history.
We have “both statutory and constitutional subject matter jurisdiction over appeals when a criminal defendant has waived his appellate rights in an enforceable plea agreement.”
United States v. Hahn,
Applying the first prong, we conclude that this appeal falls within the scope of Appellant’s waiver. Appellant signed a broad waiver. In exchange for consideration from the Government in the plea agreement, Appellant waived his right to appeal “any sentence within the guideline range” after the district court resolved the objections to the presentence report. Rec., Vol. I, at 5. The issue on appeal-whether misdemeanor convictions were properly included in Appellant’s criminal history — was raised as an objection to the *1206 presentence report. The district court held two hearings on this issue and concluded that Appellant’s misdemeanor convictions should be counted. The district court then sentenced Appellant to 21 months, the lowest end of the applicable guideline range (21 to 27 months). Rec., Vol. Ill, at 29.
Even after narrowly construing the scope of Appellant’s waiver and resolving any ambiguities in his favor,
Hahn,
A similar argument was made in
Hahn,
where the defendant’s counsel, at sentencing, “indicated that he believed Mr. Hahn was entitled to appeal,” despite the waiver of appellate rights.
Hahn,
Therefore, the guilty plea (taken pursuant to the plea agreement containing the waiver) was entered by the magistrate judge with Appellant’s consent. Although the district court later addressed the plea agreement, we have held that “absent exceptional circumstances, the district court lacks authority to modify a plea agreement at sentencing.”
United States v. Rubio,
The brеadth of the waiver is not only clear from its language but also from the magistrate judge’s colloquy. Before entering the plea, the magistrate judge asked Appellant if he understood the broad scope of his waiver. The magistrate judge clarified that Appellant had waived his right to appeal any legal sentence and tоld him that the “only exception is that after the appropriate sentencing guideline level is determined, if the sentencing judge increases — that is, makes it more sevеre— then and only then may you appeal your sentence.” Rec., Vol. I, at 8. Appellant said he understood this. Id. “We construe a defendant’s plea agreemеnt ‘according to contract principles and what the defendant reasonably understood when he entered his plea.’”
United States v. Chavez-Salais,
Notwithstanding this evidence that Appellant understood his waiver, Appellant argues that the Government, by failing to object to the district court’s statements, effectively modified the terms of the waiver and lost the right to enforce it. Although parties to a plea agreement (like parties to other contracts) can modify it, the parties here agrеed that the plea agreement “may not be altered unless done so in writing and signed by all parties.” Rec., Vol. I, at 6. We hold both a defendant and the Government to the terms of a lawful plea agreement.
See Chavez-Salais,
Applying the second prong, we hold that Appellаnt’s waiver was entered into knowingly and voluntarily. Appellant bears the burden of proof on this issue.
Hahn,
Applying the third prong, we conclude that enforcing Appellant’s waiver would not be a miscarriage of justice. “To constitute a miscarriage of justice, enforсement of [Appellant’s] waiver must result in one of the four scenarios enumerated in
[United States v. Elliott,
where the district court relied on an impermissible factor such as race, [2] where ineffective assistance of counsel in connection with the negotiation of the waiver renders the waiver invalid, [3] where the sentence exceeds the statutory maximum, or [4] where the waiver is otherwise unlawful.
Id.
at 1327 (citing
Elliott,
We enforce Appellant’s waiver and DISMISS this appeal.
