Cole Milo Maxon pleaded guilty to one count of possession with intent to distribute 50 grams or more of methamphetamine, in violation of 21 U.S.C. § 841(a)(1) (2000). After the district court 2 determined that Maxon was subject to an enhanced mandatory minimum sentence of 20 years in prison under 21 U.S.C. § 841(b)(1)(A) based on his prior conviction for a felony drug offense in North *658 Dakota state court, the district court sentenced Maxon to 240 months imprisonment followed by a 10-year term of supervised release. Maxon appeals, asserting that because his North Dakota conviction had not become final, the district court erred in relying upon that conviction to enhance his sentence under § 841(b)(1)(A). Because we conclude that Maxon’s conviction had become final under the meaning of § 841, we affirm.
I.
In 1999, Maxon pleaded guilty in North Dakota State District Court to the offense of delivery of a controlled substance (marijuana), a class B felony. In an order titled “Amended Criminal Judgment and Commitment” dated and filed November 8, 1999, the state court sentenced Maxon to three years in the state penitentiary, with all but one year and one day suspended subject to three years of supervised probation. (Appellant’s App. at 24^25.) Maxon served his time in the penitentiary and was released on supervised probation. During an authorized search of Maxon’s residence, officials discovered 50 or more grams of methamphetamine, which led to the federal indictment in this ease. Less than one month after Maxon pleaded guilty to the federal offense, the North Dakota court revoked his state probation.
A person who possesses 50 or more grams of methamphetamine with intent to distribute “after a prior conviction for a felony drug offense has become final, ... shall be sentenced to a term of imprisonment which may not be less than 20 years and not more than life imprisonment.” 21 U.S.C. § 841(b)(1)(A). The district court concluded that Maxoris prior conviction required the imposition of a 20-year minimum sentence. We review de novo the district court’s conclusions of law that are based on its interpretation of a federal statute.
See United States v. Whiting,
II.
The district court sentenced Maxon to 20 years imprisonment because it concluded that Maxoris 1999 North Dakota state conviction had “become final” under the meaning of § 841(b)(1)(A). Maxon does not dispute that the 1999 North Dakota proceedings resulted in a “conviction” and a “sentence” against him. Indeed, he served one year and one day of his sentence in the state penitentiary. Rather, he asserts that, under North Dakota law, the conviction was not “final” because the sentence was not final.
See, e.g., Davis v. State,
In Ortega, the defendant had received a suspended sentence and three years of supervised probation for a prior Missouri state drug offense. After pleading guilty to a violation of § 841(a), Ortega challenged the federal district court’s imposition of a 20-year mandatory minimum sentence based on his prior state drug offense because the imposition of a suspended sentence with probation was not considered a “final conviction” under Missouri law. In rejecting Ortega’s argument, we applied federal law to determine the meaning of “final” and held that “deferred adjudications or probated sentences constitute con- *659 vietions in the context of § 841.” Id. (quoted source and internal marks omitted). In so holding, we concluded that “Ortega’s Douglas County offense and guilty plea, for which he served supervised probation and received a suspended imposition of sentence, qualifie[d] as a prior final felony drug conviction for purposes of section 841(b)”. Id. (emphasis added).
Citing the more recent case of
United States v. Stallings,
In resolving a similar argument, the Fifth Circuit held that federal law controls the interpretation of § 841 and that “the final-conviction language of § 841(b)(1)(B) applies to a conviction which is no longer subject to examination on direct appeal ... either because of disposition on appeal and conclusion of the appellate process, or because of the passage, without action, of the time for seeking appellate review.”
United States v. Morales,
III.
For the foregoing reasons, we affirm the judgment of the district court. We deny the appellant’s motion to transfer this case to the en banc court.
