I. INTRODUCTION
Claro Rivera-Nevarez was charged in United States District Court for the District of Kansas with illegal reentry into the United States after removal, in violation of 8 U.S.C. § 1326(a) and (b)(1). Rivera-Nevarez moved to dismiss the indictment on the ground that subsequent Board of Immigration Appeals (“BIA”) and Tenth Circuit precedent rendered invalid the 1999 removal order on which the illegal reentry charge was based. The district court denied the motion, and Rivera-Neva-rez then pleaded guilty with a reservation of his right to appeal. This court has jurisdiction pursuant to 28 U.S.C. § 1291. Because Rivera-Nevarez fails to demonstrate that he fulfills the prerequisites for a collateral challenge to his 1999 removal order, this court affirms his conviction for illegal reentry.
II. BACKGROUND
Rivera-Nevarez, a citizen of Mexico, was convicted of felony driving under the influence (“DUI”) in Texas in 1997. As a direct result, he was removed from the United States in February 1999.1 At that *1106time the BIA classified DUI as a “crime of violence” under 18 U.S.C. § 16, and therefore an “aggravated felony” mandating removal under the Immigration and Naturalization Act (“INA”), 8 U.S.C. § 1227(a)(2)(A)(iii). See In re Magallanes-Garcia, 22 I. & N. Dec. 1, 5, 1998 WL 133301 (BIA 1998).2 On October 9, 2003, Rivera-Nevarez was found and arrested in Kansas without having sought or obtained permission to reapply for admission into the United States.
Charged with unlawful reentry into the United States after removal under 8 U.S.C. § 1326(a) and (b)(1), Rivera-Neva-rez moved to dismiss the indictment. He argued that subsequent interpretations by the Tenth Circuit in United States v. Lucio-Lucio, 347 F.3d 1202, 1204-06 (10th Cir.2003), and the BIA in In Re Ramos, 23 1. & N. Dec. 336, 347, 2002 WL 1001049 (BIA 2002) (en banc), established that drunk driving was not a “crime of violence” or “aggravated felony” under the INA, and that his 1999 removal on that basis was therefore invalid. The district court denied the motion, writing that “[rjetroactivity of judicial rulings is a complicated subject which defendant has not addressed in any fashion.” The court concluded that Rivera-Nevarez’s “deportation was valid under then-existing law as interpreted by the Board of Immigration Appeals and ... the Tenth Circuit.”3
In his motion for reconsideration of that ruling, Rivera-Nevarez argued that under the Supreme Court’s holding in United States v. Mendoza-Lopez a defendant being criminally prosecuted under 8 U.S.C. § 1326 could collaterally attack the prior removal order if the removal hearing was fundamentally unfair and the defendant was denied the right to appeal. 481 U.S. 828, 841-42, 107 S.Ct. 2148, 95 L.Ed.2d 772 (1987). He further argued, for the first time, that he satisfied the prerequisites for a collateral attack on his removal order established by 8 U.S.C. § 1326(d), because the BIA’s decision in Magallanes-Garcia and the general legal climate at the time of his removal hearing in 1999 rendered any attempt to appeal the removal order futile. In a second written order, the district court responded that “a motion for reconsideration does not provide an occasion to reargue the original motion or to present additional arguments which could have been submitted with it.” The court therefore “decline[dj to reconsider its order.”
Rivera-Nevarez subsequently entered into a plea agreement with the government, which allowed him to plead guilty to the offense and reserve the right to appeal “those issues raised in his Motion to Dismiss and Motion to Reconsider.” The district court accepted the conditional guilty plea and sentenced Rivera-Nevarez to 21 months’ imprisonment. This appeal ensued.
*1107On November 9, 2004, the Supreme Court announced its decision in Leocal v. Ashcroft, — U.S. -, 125 S.Ct. 377, 160 L.Ed.2d 271 (2004). The Court had granted certiorari in Leocal to resolve a conflict among the circuits on the question whether DUI offenses that do not have a mens rea component or require only a showing of negligence in the operation of a vehicle qualify as a crime of violence. Id. at 380.4 In Leocal, the Court held that such DUI offenses are not crimes of violence under 18 U.S.C. § 16, and therefore are not “aggravated felonies” under the INA. Id. at 383.
III. DISCUSSION
A. Retroactive Applicability of Lucio-Lucio and Leocal
In denying Rivera-Nevarez’s motion to dismiss the indictment, the district court concluded that the BIA’s decision in Ramos and this court’s decision in Lucio-Lucio were not retroactively applicable and that the removal was therefore valid at the time it occurred. Subsequently, the Supreme Court’s decision in Leocal has conclusively established that DUI is not a “crime of violence” under the INA. 125 S.Ct. at 383. Because Leocal involves a question of statutory construction, its holding is retroactively applicable to the time of Rivera-Nevarez’s removal hearing. Decisions of statutory interpretation are fully retroactive because they do not change the law, but rather explain what the law has always meant. See Rivers v. Roadway Express Inc., 511 U.S. 298, 312-13, 114 S.Ct. 1510, 128 L.Ed.2d 274 (1994) (“A judicial construction of a statute is an authoritative statement of what the statute meant before as well as after the decision of the case giving rise to that construction.”). For this reason, Leocal provides the correct interpretation of the law as it stood in 1999 when Rivera-Nevarez was deported. See United States v. Shelton, 848 F.2d 1485, 1489-90 (10th Cir.1988) (en banc). The district court’s conclusion that Rivera-Nevarez’s removal was valid at the time it occurred was therefore in error.
B. Section 1326(d) and Collateral Review of the Removal Order
Athough the district court erred in its conclusion that the rule announced in Ramos and Lucio-Lucio was not retroactively applicable to the removal proceeding, Rivera-Nevarez nevertheless cannot collaterally challenge his removal unless he can establish that he meets the statutory prerequisites for a collateral attack set forth in 8 U.S.C. § 1326(d). See United States v. Wittgenstein, 163 F.3d 1164, 1170 (10th Cir.1998). Because Rivera-Nevarez fails to demonstrate that the statutory requirements for a collateral attack are satisfied, this court concludes that he cannot challenge his removal in this criminal prosecution. The district court’s error was therefore harmless.
Section 1326 criminalizes reentry into the United States after removal without obtaining advance consent from the Attorney General. 8 U.S.C. § 1326(a). The language of the statute as originally enacted included no exception for cases in which the original removal order was unlawful. See Mendoza-Lopez, 481 U.S. at 835, 107 S.Ct. 2148. The statute provided simply that any alien who “has been ... deported” will be guilty of a felony if the alien *1108thereafter enters the United States. See id at 835-37, 107 S.Ct. 2148 (concluding that Congress did not intend criminal liability under § 1326 to depend on the validity of the underlying deportation order).
In Mendoza-Lopez, however, the Supreme Court held that when an administrative removal proceeding plays a critical role in the subsequent imposition of a criminal sanction, the proceeding must be conducted in accordance with due process and “there must be some meaningful review of the administrative proceeding.” Id. at 837-838, 107 S.Ct. 2148; see also United States v. Aguirre-Tello, 353 F.3d 1199, 1204 (10th Cir.2004) (en banc). Mendoza-Lopez distinguished the Court’s earlier opinion in Lewis v. United States, in which the Court held that Congress could define the “class of persons who should be disabled from dealing in or possessing firearms” by reference to prior state felony convictions, even if those convictions had been obtained in proceedings where the defendant was deprived of counsel in violation of the Sixth Amendment. Lewis, 445 U.S. 55, 67-68, 100 S.Ct. 915, 63 L.Ed.2d 198 (1980). The Court in Lewis noted that convicted felons had access to procedures by which they could judicially challenge the validity of their convictions prior to obtaining firearms. Id. at 67, 100 S.Ct. 915. In contrast, the Court in Mendoza-Lopez concluded that the defendant was deprived of the opportunity to judicially challenge the deportation order because he was not adequately informed of his right to appeal. Mendoza-Lopez, 481 U.S. at 839-40, 107 S.Ct. 2148. The Court wrote that “[i]t is precisely the unavailability of effective judicial review of the administrative determination at issue here that sets this case apart from Lewis.” Id. at 841, 107 S.Ct. 2148.
In response to Mendoza-Lopez, Congress enacted § 1326(d), which establishes three requirements that an alien must satisfy in order to collaterally challenge a removal proceeding as a defense to a criminal prosecution for illegal reentry. See United States v. Sandoval, 390 F.3d 1294, 1298-99 & 1299 n. 3 (10th Cir.2004). Section 1326(d) requires the alien to demonstrate that:
(1) the alien exhausted any administrative remedies that may have been available to seek relief against the order;
(2) the deportation proceedings at which the order was issued improperly deprived the alien of the opportunity for judicial review; and
(3) the entry of the order was fundamentally unfair.
8 U.S.C. § 1326(d). This court has held that § 1326(d) comports with the constitutional standard for due process set forth in Mendoza-Lopez. Wittgenstein, 163 F.3d at 1170.
Under both § 1326(d) and Mendoza-Lopez, a criminal defendant challenging a prior removal order must show not only that the removal proceeding was fundamentally unfair, but also that the defendant was improperly deprived of the opportunity for judicial review. 8 U.S.C. § 1326(d)(2)-(3); Mendoza-Lopez, 481 U.S. at 838, 107 S.Ct. 2148 (“[Wjhere the defects in an administrative proceeding foreclose judicial review of that proceeding, an alternative means of obtaining judicial review must be made available before the administrative order may be used to establish conclusively an element of a criminal offense.”); Wittgenstein, 163 F.3d at 1170 (“A defendant may collaterally challenge a deportation hearing in a 8 U.S.C. § 1326 prosecution if the defendant can show that the deportation hearing was fundamentally unfair and deprived the alien to the right of judicial review.” (quotation omitted)); see also Aguirre-Tello, 353 F.3d at 1204. As this court wrote in *1109United States v. Aranda-Hernandez: “The right to judicial review does not establish a right to an error-free immigration hearing. It grants a right to appeal if the immigration judge errs in construing the law or facts of the case.” 95 F.3d 977, 981 (10th Cir.1996).
Assuming, without deciding, that Rivera-Nevarez can demonstrate that his removal proceeding was fundamentally unfair and that he properly exhausted any administrative remedies, he nevertheless fails to meet his burden under § 1326(d)(2) to show that he was deprived of the opportunity for judicial review. The prior removal proceeding is afforded a presumption of regularity, and the defendant has the burden of showing that he was deprived of his right to appeal. Aguirre-Tello, 353 F.3d at 1204. Rivera-Nevarez notes that, at the time of his removal hearing, jurisdiction-stripping provisions in IIRIRA precluded direct appeal of “any final order of removal against an alien who is removable by reason of having committed a criminal offense [including an aggravated felony].” 8 U.S.C. § 1252(a)(2)(C). Because § 1252(a)(2)(C), as applied under the law as it stood in 1999, appeared to preclude any right to appellate review of the removal order, Rivera-Nevarez argues that the requirement of § 1326(d)(2) is satisfied.
Although Rivera-Nevarez is correct that § 1252(a)(2)(C) precluded appellate review of removal orders based on an alien’s commission of a crime of violence, it did not preclude courts from reviewing the threshold question of which particular crimes constitute crimes of violence under the INA. The Fifth Circuit, from which Rivera-Nevarez was removed, held in February 2000 that although IIRIRA stripped federal courts of jurisdiction for direct review, the courts retain jurisdiction to determine whether the specific conditions that bar jurisdiction exist. Max-George v. Reno, 205 F.3d 194, 199 (5th Cir.2000), vacated on other grounds sub nom. Max-George v. Ashcroft, 533 U.S. 945, 121 S.Ct. 2585, 150 L.Ed.2d 746 (2001).5 Rivera-Nevarez therefore could have appealed to the Fifth Circuit on the question whether DUI constituted a crime of violence within the meaning of the INA. See, e.g., United States v. Chapa-Garza, 243 F.3d 921, 924-27 (5th Cir.2001).
Maxr-George had not been decided at the time of Rivera-Nevarez’s removal hearing in 1999, but the Fifth Circuit at that time had construed the INA’s very similar transitional jurisdiction-stripping provision, 8 U.S.C. § 1105a(10), in the same manner. Okoro v. INS, 125 F.3d 920, 925 & n. 10 (5th Cir.1997).6 In Okoro v. INS, the Fifth Circuit interpreted § 1105a(10) to leave the court with jurisdiction to review the question whether the underlying offense leading to removal was one of the offenses for which judicial review was precluded by the statute. Id. (noting that a court has jurisdiction to determine whether it has jurisdiction). Other circuits had reached the same conclusion by the time of Rivera-Nevarez’s removal. See, e.g., Yang v. INS, 109 F.3d 1185, 1192 (7th Cir.1997). In addition, the Eleventh Circuit in Richardson v. Reno had found 8 U.S.C. § 1252(a)(2)(C), the same statutory provision at issue here, to *1110allow for judicial review over the question whether the predicate offense was included within the jurisdiction-stripping statute. 162 F.3d 1338, 1375-76 (11th Cir.1998), vacated on other grounds, 526 U.S. 1142, 119 S.Ct. 2016, 143 L.Ed.2d 1029 (1999).7
The precise question of whether DUI constituted a crime of violence and therefore an aggravated felony under the INA had not yet been decided by the Fifth Circuit at the time of Rivera-Nevarez’s removal hearing. Several circuits, however, had suggested in dicta that DUI was not a crime of violence. See United States v. Parson, 955 F.2d 858, 864-66 (3d Cir. 1992) (contrasting the definition of “crime of violence” under 18 U.S.C. § 16, the definition at issue here, with the relatively broader definition of the phrase under the United States Sentencing Guidelines); see also United States v. Rutherford, 54 F.3d 370, 372-74, 374 n. 11, 377 (7th Cir.1995); United States v. Doe, 960 F.2d 221, 225 (1st Cir.1992). In March 2001 the Fifth Circuit ultimately agreed that the Texas felony DUI offense was not a crime of violence for purposes of the INA. Chapa-Garza, 243 F.3d at 926-27; accord Leocal, 125 S.Ct. at 383.8 The fact that this was still an open question in the Fifth Circuit at the time of Rivera-Nevarez’s removal hearing in February 1999, while adding some uncertainty to his chances of prevailing on appeal, cannot be said to have effectively eliminated his right to obtain judicial review.9
Rivera-Nevarez also briefly contends, without citation to the record, that he was not informed at the removal proceeding of his right to “relief.” Presuming that by the term “relief’ he means judicial review, this argument fails to satisfy Rivera-Neva-rez’s burden under § 1326(d)(2). Attached to Rivera-Nevarez’s brief is a copy of a “Notice to Appear” signed by Rivera-Nev-arez and notifying him of his right to appeal an adverse decision by the immigration judge. Also attached is an order by the immigration judge noting that ap*1111peal was waived. There is no indication in the record that the notice was insufficient or that the waiver was otherwise inadequate. See United States v. Rangel de Aguilar, 308 F.3d 1134, 1139 (10th Cir. 2002) (rejecting an alien’s challenge to the validity of a waiver of appeal when the alien presented no evidence that the waiver was invalid). Nor did Rivera-Nevarez ever request the opportunity to introduce evidence to this effect in the district court. See Sandoval, 390 F.3d at 1301 (“Generally speaking, an evidentiary hearing is not required unless the requesting party shows that he will produce relevant evidence.”). In the absence of evidence to the contrary, this court cannot presume that the removal hearing improperly precluded Rivera-Nevarez’s right to judicial review. See United States v. Arevalo-Tavares, 210 F.3d 1198, 1200-01 (10th Cir. 2000).
Because Rivera-Neverez has failed to demonstrate that he satisfied the requirements of § 1326(d) by showing that he was deprived of the opportunity for direct review of his removal order, collateral review of the order in this criminal prosecution is precluded. See Aranda-Hernandez, 95 F.3d at 981 (holding that this court will not collaterally review error in a removal hearing when an alien has waived direct review of the error in the court of appeals). The district court’s error in denying the motion to dismiss was therefore harmless.
C. Rule 11(a)(2)
The dissent reads Federal Rule of Criminal Procedure 11(a)(2) to mandate a per se rule of reversal for cases where a district court, while reaching the correct result, relies on erroneous reasoning in deciding an issue reserved for appeal as part of a conditional plea agreement.10 This rule would apparently apply regardless of whether the defendant must inevitably lose in the district court on other grounds. Under the dissent’s interpretation, any error committed by the district court and appealed by the defendant pursuant to Rule 11(a)(2), regardless of whether harmless or irrelevant, would constitute grounds for withdrawal of a plea. The dissent would therefore remand this case because the district court erred on the question of the retroactivity of Lucio-Lucio, without a discussion of whether § 1326(d) would even have allowed Rivera-Nevarez to make the retroactivity argument in the first place.
As an initial matter, the dissent is wrong in its view that the terms of the plea agreement itself restrict this court from considering the requirements of § 1326(d). Rivera-Nevarez reserved the right “to appeal ... those issues raised in his Motion to Dismiss and Motion to Reconsider.” Although Rivera-Nevarez did not discuss § 1326(d) in his initial motion to dismiss, he did address the requirements of the statute in his motion to reconsider, which was expressly included among the issues reserved for appeal in his plea agreement. Furthermore, both Rivera-Nevarez and the government verified that § 1326(d) issues were reserved for appeal by presenting extensive arguments thereon in their respective appellate briefs. In this context, the dissent’s citation to the statement of issues in Rivera-Nevarez’s brief is not a persuasive basis upon which to limit this *1112court’s authority to decide relevant issues.11
In spite of the language in the plea agreement indicating that § 1326(d) was at issue on appeal, the dissent would nevertheless refuse to consider the issue because the district court resolved the case on other grounds.12 We do not, however, share the dissent’s reading of Rule 11(a)(2) to allow for Rivera-Nevarez to withdraw his guilty plea if the district court is found to have committed an error of law that has no effect on the outcome of the case. Rivera-Nevarez reserved only the right to “appeal.” He has now exercised his right, and we have found the decision of the district court to be correct.13 Given that the district court reached the correct result in this case, it is irrelevant whether any particular reasoning within the court’s written orders is faulty. Cf. Herb v. Pitcairn, 324 U.S. 117, 126, 65 S.Ct. 459, 89 L.Ed. 789 (1945) (“[0]ur power is to correct wrong judgments, not to revise opinions.”).
The dissent’s extraordinary interpretation of Rule 11(a)(2) is unprecedented in the history of this court. It is a fundamental and long-accepted feature of appellate review that a court of appeals may “affirm the rulings of the lower court on any ground that finds support in the record, even where the lower court reached its conclusions from a different or even erroneous course of reasoning.” Keyes v. Sch. Dist. No. 1, Denver, Colo., 521 F.2d 465, 472-73 (10th Cir.1975). As early as 1937, this rule was considered “inveterate and certain.” Morley Constr. Co. v. Md. Cas. Co., 300 U.S. 185, 191, 57 S.Ct. 325, 81 L.Ed. 593 (1937); see Jaffke v. Dunham, 352 U.S. 280, 77 S.Ct. 307, 308-09, 1 L.Ed.2d 314 (1957); United States v. Am. Ry. Express Co., 265 U.S. 425, 435, 44 S.Ct. 560, 68 L.Ed. 1087 (1924). This historical principle is supported by the consistent practice of this court, even in cases appealed in accordance with Rule 11(a)(2). See, e.g., United States v. Cusumano, 83 F.3d 1247, 1248, 1249-50 (10th Cir.1996) (en banc) (affirming the denial of a suppression motion in a Rule 11(a)(2) appeal on grounds other than those relied on by the district court). In light of this court’s long-established views, it is not surprising that the dissent cites no authority in sup*1113port of its novel interpretation of Rule 11(a)(2).14
Even if the dissent were correct that this court could not resolve the case on any grounds not decided by the district court, the fault for the district court’s failure to address the § 1326(d) issue lies entirely with Rivera-Nevarez. The only reason the district court did not reach the question was because it was never raised in Rivera-Nevarez’s motion to dismiss. The district court, in the absence of argument on the permissibility of a collateral attack, understandably focused solely on Rivera-Nevarez’s assertion that Lucio-Lucio should be applied retroactively to the removal hearing. The irony of the dissent’s approach is that, having neglected to argue an essential prerequisite to his collateral attack on the removal order, Rivera-Neva-rez would now be rewarded for the district court’s failure to rule on the issue. We cannot accept such a result.
IV. CONCLUSION
For the foregoing reasons, Rivera-Nev-arez’s conviction is AFFIRMED.
. The Illegal Immigration Reform and Immigrant Responsibility Act of 1996 ("IIRIRA”), Pub.L. No. 104-208, 110 Stat. 3009 and the Antiterrorism and Effective Death Penalty Act of 1996 ("AEDPA”), Pub.L. No. 104-132, 110 Stat. 1214, changed the terminology for removal of resident aliens, replacing the term “deportation" with "removal." See Jurado-Gutierrez v. Greene, 190 F.3d 1135, 1140 n. 2 (10th Cir.1999).
. The INA defines "aggravated felony” to include "a crime of violence (as defined in section 16 of Title 18, but not including a purely political offense) for which the term of imprisonment [is] at least one year.” 8 U.S.C. § 1101(a)(43)(F). The term "crime of violence” is in turn defined as:
(a) an offense that has as an element the use, attempted use, or threatened use of physical force against the person or property of another, or
(b) any other offense that is a felony and that, by its nature, involves a substantial risk that physical force against the person or property of another may be used in the course of committing the offense.
18 U.S.C. §16.
. The district court's order included no discussion of the prerequisites established by 8 U.S.C. § 1326(d) for a collateral challenge to a prior removal order, presumably because Rivera-Nevarez did not argue in his motion that he satisfied those prerequisites.
. Among the cases cited by the Supreme Court was the Fifth Circuit case, United States v. Chapa-Garza, 243 F.3d 921, 927 (5th Cir. 2001), in which the court held that the Texas felony driving while intoxicated statute was not a crime of violence within the meaning of 18 U.S.C. § 16(b). Leocal v. Ashcroft, - U.S. -, -, 125 S.Ct. 377, 380, 160 L.Ed.2d 271 (2004).
. In January 2001, this court agreed with the Fifth Circuit's conclusion in Max-George that federal courts retain jurisdiction to determine whether the jurisdictional bar under § 1252(a)(2)(C) applies. Tapia Garcia v. INS, 237 F.3d 1216, 1220 (10th Cir.2001).
. The transitional provision stated that "[a]ny final order of deportation against an alien who is deportable by reason of having committed [enumerated criminal offenses] shall not be subject to review by any court.” 8 U.S.C. § 1105a(10) (repealed 1996).
. This court reached the opposite result regarding IIRIRA's temporary jurisdiction-stripping provision in Berehe v. INS, 114 F.3d 159, 161-62 (10th Cir.1997). In Tapia Garcia, however, this court distinguished Berehe and concluded that IIRIRA's permanent provision left the court with jurisdiction to determine whether it had jurisdiction to hear an appeal. 237 F.3d at 1220.
. In September 1999, the Fifth Circuit held that the Texas felony DUI statute was a crime of violence under the INA, and therefore that the jurisdictional bar applied. Camacho-Marroquin v. INS, 188 F.3d 649 (5th Cir. 1999), withdrawn, 222 F.3d 1040 (5th Cir. 2000). This opinion was withdrawn in July 2000, and in Chapa-Garza the court ultimately came to the opposite conclusion. 243 F.3d at 926-27.
. Other courts have suggested that an alien's right to file a petition for habeas corpus in federal district court is sufficient to satisfy the § 1326(d)(2) judicial review requirement. See, e.g., United States v. Copeland, 376 F.3d 61, 67-68 (2d Cir.2004); United States v. Roque-Espinoza, 338 F.3d 724, 729 (7th Cir. 2003). Although the Fifth Circuit in Max-George v. Reno, 205 F.3d 194, 198 (5th Cir. 2000), held that IIRIRA’s jurisdiction-stripping provisions precluded habeas relief in addition to direct review, at the time of Rivera-Nevarez's removal proceeding Fifth Circuit law still held that the transitional provisions of IIRIRA and AEDPA did not completely eliminate habeas review. See Lerma de Garcia v. INS, 141 F.3d 215, 217 (5th Cir.1998); see also United States v. Torres, 383 F.3d 92, 101 n. 7 (3d Cir.2004) (concluding that Fifth Circuit law in 1998 did not preclude habeas relief). The availability of habeas review of removal orders was confirmed by the Supreme Court in INS v. St. Cyr, 533 U.S. 289, 312-13, 121 S.Ct. 2271, 150 L.Ed.2d 347 (2001). Because we conclude that Rivera-Nevarez could have directly appealed his removal order, we need not decide whether habeas relief would have been available to Rivera-Nevarez in 1999, and whether the availability of this form of judicial review would satisfy the requirement of § 1326(d)(2).
. Rule 11(a)(2) states:
Conditional Plea. With the consent of the court and the government, a defendant may enter a conditional plea of guilty or nolo contendere, reserving in writing the right to have an appellate court review an adverse determination of a specified pretrial motion. A defendant who prevails on appeal may then withdraw the plea.
Fed.R.Crim.P. 11(a)(2).
. The fact that the motion to reconsider was included among the issues reserved for appeal answers the dissent's argument that this court’s resolution of the case violates Rivera-Nevarez's due process right to be convicted only on the basis of a knowing and intelligent plea. Even barring a consideration of the motion to reconsider, the government's argument in response to the original motion to dismiss that § 1326(d) barred a collateral challenge to the removal order should have been sufficient to put Rivera-Nevarez on notice that the issue would be at play on appeal.
. We note that the dissent's argument was never raised by the defendant. The defendant's briefing on the question of § 1326(d)(2) was limited to his contention that he satisfied his burden under the statute because "any attempt ... to contest [the immigration judge's] decision would have been futile in the [legal] climate that existed in 1999,” a contention that we have fully considered and rejected. See Part III.B, supra. Rivera-Nevarez’s counsel did request at oral argument that we remand to the district court if we concluded that the district court erred in its retroactivity analysis, but issues raised for the first time at oral argument are waived. Durham v. Xerox Corp., 18 F.3d 836, 841 n. 4 (10th Cir.1994).
.Rule 11(a)(2) allows for withdrawal of a plea only for a defendant "who prevails on appeal.” Fed.R.Crim.P. 11(a)(2) (emphasis added). There is no reason to believe that a party appealing pursuant to Rule 11(a)(2) is exempt from Rule 52(a)'s requirement that "[a]ny error ... that does not affect substantial rights must be disregarded.” Fed. R.Crim.P. 52(a); see Fed.R.Crim.P. 11(a)(2) advisory committee's note to 1983 amendments (discussing the role of harmless error under Rule 11(a)(2)).
. The dissent's citation to United States v. Leake, 95 F.3d 409 (6th Cir. 1996), is inappo-site. In that case, the Sixth Circuit determined that the district court erred in denying the defendant's motion to suppress because the motion should have been granted in part and denied in part. Id. at 420. The court concluded that the district court’s error was prejudicial to the defendant because the partial grant of the motion would have resulted in "excluding what appears to be the most damning evidence” in the case. Id. The court was careful to note, however, that not all defendants who succeed in achieving partial suppression of evidence on appeal are entitled to withdraw their conditional guilty pleas. Id. at 420 n. 21. Rather, whether a defendant should be allowed to do so would depend on "an examination of the degree of success and the probability that the excluded evidence would have had a material effect on the defendant's decision to plead guilty.” Id. In contrast to Leake, the district court in this case reached the correct result, and the erroneous reasoning in the court’s written order resulted in no prejudice to Rivera-Nevarez.
The dissent’s citation to United States v. Mejia, 69 F.3d 309 (9th Cir.1995), misses the mark for the same reason. Mejia noted only that when a defendant appeals the district court's denial of two separate suppression orders, reversal of either one of the orders warrants a withdrawal of the plea agreement if the denial of that order prejudiced the defendant. Id. at 316 n. 8. The other case cited by the dissent, United States v. Tantalo, involved a similar situation in which the district court reached an erroneous and prejudicial result on one of two issues appealed. 680 F.2d 903, 911 (2d Cir.1982). Neither of these cases have anything to say about whether a court of appeals can affirm a district court on alternate grounds when the district court's ultimate decision is correct.
