OPINION

Aurelio Duran Gonzalez, along with six individuals (“Plaintiffs”), voluntarily filed applications for adjustment of status, thus disclosing that they were aliens who had been removed and had reentered the United States without inspection. They did this in reliance on the Ninth Circuit’s opinion in Perez-Gonzalez v. Ashcroft, 379 F.3d 783 (9th Cir.2004), wherein the court purportedly held that individuals like Plaintiffs were eligible for relief. The district court certified Plaintiffs’ proposed class and issued a preliminary injunction.

The government appealed, and in Duran Gonzales v. Department of Homeland Security, 508 F.3d 1227 (9th Cir.2007) (“Duran Gonzales II ”), we held that, pursuant to the Supreme Court’s directions in National Cable & Telecommunications Ass’n v. Brand X Internet Services, 545 U.S. 967, 981-985 , 125 S.Ct. 2688 , 162 L.Ed.2d 820 (2005) (“Brand X ”), we were compelled to follow the 2006 opinion by the Board of Immigration Appeals (“BIA”) in In re Torres-Garcia, 23 I. & N. Dec. 866 (BIA 2006). In In re Torres-Garcia, the BIA held that individuals such as Plaintiffs were not eligible for relief. We held that, because this was a reasonable interpretation of a statute by the agency charged with interpreting and enforcing the statute, and because our prior opinion in Perez-Gonzalez was based on the statute’s ambiguity, Brand X required that we defer to the BIA’s interpretation of the statute, even though it was contrary to our prior interpretation of the statute in Perez-Gonzalez. Duran Gonzales II, 508 F.3d at 1242 .

Accordingly, we vacated the district court’s injunction and remanded the matter. Our opinion stated that “[pjursuant to In re Torres-Garcia, plaintiffs as a matter of law are not eligible to adjust their status because they are ineligible to receive 1-212 waivers.” Id. On remand, the district court held that Duran Gonzales II was binding, declined to allow Plaintiffs to amend their complaint or the class certification, and dismissed Plaintiffs’ action.

Plaintiffs appeal, arguing that Duran Gonzales II should be given prospective application only. We affirm the district court’s dismissal of the action because Du ran Gonzales II applied its ruling to the Plaintiffs, and another three-judge panel has held that Duran Gonzales II has retroactive application. See Morales-Izquierdo v. Dep’t of Homeland Sec., 600 F.3d 1076, 1086 (9th Cir.2010).

I

Plaintiffs are individuals who are not citizens of the United States, who were previously deported or removed from the United States, and who reentered the United States without inspection. After returning to the United States, Plaintiffs sought to adjust their immigration status by filing applications for adjustment of status under 8 U.S.C. § 1256 . The statute “allowed the Attorney General to adjust the status of an alien who had entered the United States without inspection to that of a legal permanent resident provided that the alien (1) was admissible to the United States and the beneficiary of an immediately available immigrant visa, and (2) paid an application fee five times the usual fee.” Duran Gonzales II, 508 F.3d at 1230 .

Plaintiffs’ course to adjustment of status, however, was complicated by two provisions of the Illegal Immigration Reform and Immigrant Responsibility Act of 1996 (“IIRIRA”). The first appeared to deny Plaintiffs relief. Title 8 U.S.C. § 1231 (a)(5) provides “for automatic reinstatement of an alien’s prior removal or deportation order when an alien has reentered the United States illegally,” and further provides that the “alien is not eligible and may not apply for any relief.” Duran Gonzales II, 508 F.3d at 1230 .

The second section suggested a possible exception to this bar. Although 8 U.S.C. § 1182 (a)(9)(C)(i) provides that an alien “who enters or attempts to reenter the United States without being admitted is inadmissible,” § 1182(a)(9)(C)(ii) creates an exception for

8 U.S.C. § 1182 (a)(9)(C)(ii). The exception had two conditions of particular relevance to Plaintiffs: (1) it was only available if made more than 10 years after the alien’s last departure; and (2) the application has to be made from outside the United States.

Plaintiffs, however, found encouragement in our opinion in Perez-Gonzalez , which held “that the INS committed legal error when it concluded that Perez-Gonzalez could not apply for a Form 1-212 waiver from within this country.” Perez-Gonzalez, 379 F.3d at 789 . Accordingly, Plaintiffs filed both 1-212 forms seeking relief under § 1182(a)(9)(C)(ii) and applications for adjustment of status under § 1255(i) with the United States Citizenship and Immigration Services (“USCIS”). USCIS denied three of the Plaintiffs’ applications on the ground that the ten-year period had not elapsed since the dates of the applicants’ last departures from the United States.

Plaintiffs then filed their complaint with the United States District Court for the Western District of Washington. They argued that USCIS’s position — that an alien’s failure to meet the ten-year requirement barred a successful 1-212 application — -was contrary to Perez-Gonzalez , and sought injunctive and declaratory relief, a temporary restraining order, and class certification. The district court granted a preliminary injunction and certified a class. The Department of Homeland Security filed a timely appeal.

II

On appeal, we were constrained by the Supreme Court’s opinion in Brand X, 545 U.S. 967 , 125 S.Ct. 2688 , in which the Court “held that the circuit court must apply Chevron, U.S.A., Inc. v. Natural Resources Defense Council, Inc., 467 U.S. 837 , 104 S.Ct. 2778 , 81 L.Ed.2d 694 (1984) deference to an agency’s interpretation of a statute regardless of the circuit court’s contrary precedent, provided that the court’s earlier precedent was an interpretation of a statutory ambiguity.” Duran Gonzales II, 508 F.3d at 1235-36 . We determined “that, despite some language to the contrary, Perez-Gonzalez was based on a finding of statutory ambiguity that left room for agency discretion.” Id. at 1237. We explained:

Id. at 1238-39. We recognized that in deciding In re Torress-Garcia the BIA considered various interpretations of the statutes, including our approach in Perez-Gonzalez , and found “the more reasonable interpretation of the statutory framework to be that an alien may not obtain a waiver under subsection (a)(9)(C)(ii), retroactively or prospectively, without regard to the ten-year bar.” Id. at 1241. We determined that the BIA’s decision was “clearly reasonable” and entitled to Chevron deference under Brand X. Id. at 1242.

The final paragraph in Duran Gonzales II states:

508 F.3d at 1242-43 (emphasis added). Plaintiffs filed a petition for rehearing and suggestion for rehearing which included an argument that the opinion should not be applied retroactively. The panel denied the petition for rehearing, and a majority of the active judges declined the suggestion for rehearing en banc.

In the district court on remand, Plaintiffs argued that Duran Gonzales II should be given prospective application only and not applied to them. They also sought to amend their class certification to include only those individuals who filed I-212 applications prior to our opinion in Duran Gonzales II.

The district court rejected Plaintiffs’ arguments, denied their motion to amend class certification, denied their motion to file an amended complaint, and dismissed the action. The district court rejected Plaintiffs’ argument against Duran Gonzales ITs retroactivity because “the Circuit court stated conclusively that the BIA’s interpretation of the statute applied to Plaintiffs,” and held that “the retroactive application of In re Torres-Garda is simply not an open question before this Court.” The court reasoned that allowing Plaintiffs to amend their complaint or to amend their class certification would be futile because neither amendment could change the presumptive retroactive effect of Duran Gonzales II. Plaintiffs filed this timely appeal.

Ill

Following our remand in Duran Gonzales II, we issued two opinions that bear on our consideration of this appeal: Morales-Izquierdo, 600 F.3d 1076 , and Nunez-Reyes v. Holder, 646 F.3d 684 (9th Cir. 2011) (en banc).

A. Morales-Izquierdo v. Holder

Raul Morales, a citizen of Mexico, illegally entered the United States in 1990. After being arrested by the INS, Morales was ordered removed in 1994 and was actually removed to Mexico in 1998. 600 F.3d at 1079 . He subsequently reentered the United States, again without inspection, in 2001. Id. After being removed but before reentering, Morales married a United States citizen. Id. Following his reentry without inspection, Morales sought to adjust his status through his citizen-wife. Id. In 2003, Morales was taken into eustody, his application for adjustment of status was denied, and a Notice of Intent to/Decision to Reinstate Prior Order (on the basis of his 1998 removal) was issued. Id. at 1079-80 .

Morales filed several petitions seeking review of these actions. We granted his initial petition for review of the reinstatement order. Morales-Izquierdo v. Ashcroft, 388 F.3d 1299 (9th Cir.2004). Further litigation ensued, however, and when his case was again before us in 2010, one of the issues was whether Duran Gonzales II applied to his situation. We explained:

Morales-Izquierdo, 600 F.3d at 1086 .

In rejecting Morales’s argument, we started with the standard that “[ojrdinarily, ‘[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.’ ” Id. at 1087-88 (quoting Rivers v. Roadway Express, Inc., 511 U.S. 298, 312-13 , 114 S.Ct. 1510 , 128 L.Ed.2d 274 (1994)). We further commented that “[t]hus, when a court applies a statute to the parties before it, ‘that rule is the controlling interpretation of federal law and must be given full retroactive effect in all cases still open on direct review and as to all events, regardless of whether such events predate or postdate [the] announcement of the rule.’” Id. at 1088 (quoting Harper v. Va. Dep’t of Taxation, 509 U.S. 86, 97 , 113 S.Ct. 2510 , 125 L.Ed.2d 74 (1993)).

We rejected Morales’s argument that Duran-Gonzales II was similar to an agency decision and its retroactivity should be evaluated pursuant to a multi-factor standard. We held:

Morales-Izquierdo, 600 F.3d at 1089 .

Our reasoning led us to reject Morales’s request for “a nunc pro tunc Form 1-212 waiver to cure his inadmissibility and make him eligible for adjustment of status.” Id. at 1090 . We held that “the law of our circuit in Gonzales explicitly and without apology holds that 8 U.S.C. § 1182 (a)(9)(C) ... does not permit such waivers.” Id. at 1091 . We concluded that the statute and our precedent were controlling and that “a Form 1-212 waiver cannot cure Morales’s inadmissibility until the expiration of the ten-year bar.” Id.

B. Nunez-Reyes v. Holder

Flavio Nunez-Reyes entered the United States in 1992 and in 2001 was charged in state court with a felony count and a misdemeanor count involving methamphetamine. He pled guilty to both counts and the state court subsequently dismissed the charges under a state provision wherein courts were directed to set aside convictions and dismiss indictments should a defendant successfully complete a drug treatment program along with other conditions. Under the California provision, “both the arrest and the conviction shall be deemed never to have occurred.” Nunez-Reyes, 646 F.3d at 687 . In 2002, the federal government found Nunez-Reyes removable, and his applications for adjustment of status and petition for cancellation of removal were denied by the BIA. Id.

The en banc panel first overruled our prior decision in Lujan-Armendariz v. INS, 222 F.3d 728 (9th Cir.2000), and held “that the constitutional guarantee of equal protection does not require treating, for immigration purposes, an expunged state conviction of a drug crime the same as a federal drug conviction that has been expunged under the” Federal First Offender Act. Nunez-Reyes, 646 F.3d at 690 .

The panel, however, determined that this holding “will apply only prospectively.” Id. at 694 . The panel recognized that the “default principle is that a court’s decisions apply retroactively to all cases still pending before the courts.” Id. at 690 . However, “courts may depart from that default principle only in certain circumstances, as outlined in” Chevron Oil Co. v. Huson, 404 U.S. 97 , 92 S.Ct. 349 , 30 L.Ed.2d 296 (1971). Nunez-Reyes, 646 F.3d at 690 . Before applying the Chevron Oil factors, the panel noted that “a court announcing a new rule of law must decide between pure prospectivity and full retro-activity.” Id. (citing James B. Beam Distilling Co. v. Georgia, 501 U.S. 529, 537-38 , 111 S.Ct. 2439 , 115 L.Ed.2d 481 (1991) (Souter J., plurality opinion)).

The panel identified the Chevron Oil factors as: “(1) whether the decision establishes] a new principle of law; (2) whether retrospective operation will further or retard [the rule’s] operation in light of its history, purpose, and effect; and (3) whether our decision could produce substantial inequitable results if applied retroactively.” Nunez-Reyes, 646 F.3d at 692 (internal quotation marks and citation omitted). The panel found that there was no question that its ruling established a new principle of law. Id. It next determined that the retroactive application of its decision created the potential for unfairness, explaining:

Nunez-Reyes, 646 F.3d at 693-94 . Finally, the panel concluded that the second Chevron Oil factor was met: “retroactive application will not further the rule’s operation.” Id. at 694 . The court reasoned that “Congress did not intend adverse immigration consequences for those who were merely charged with a crime or suspected of a crime.” Id.

As explained in the next section, the principles set forth in Morales-Izquierdo and Nunez-Reyes require that we affirm the district court’s dismissal of Plaintiffs’ complaint.

IV

Although the district court’s denial of leave to amend is reviewed for abuse of discretion, Gardner v. Martino, 563 F.3d 981, 990 (9th Cir.2009), as is an order on class certification, Parra v. Bashas’, Inc., 536 F.3d 975, 977 (9th Cir. 2008), the essence of Plaintiffs’ appeal is that the district court erred in holding that Duran Gonzales II applied to them. This underlying conclusion of law is reviewed de novo. See Citizens for Clean Gov’t v. City of San Diego, 474 F.3d 647, 650 (9th Cir. 2007).

On appeal, Plaintiffs assert that the district court erred in holding that Duran Gonzales II applied retroactively to all class members and in failing to independently determine whether it should be applied to them. We disagree and hold that the district court could not have determined that Duran Gonzales II applied prospectively only and hold that we are unable to give Duran Gonzales II only prospective application.

A. The District Court Could Not Determine That Duran Gonzales II Applies Prospectively Only.

We reiterated in Nunez-Reyes that the “default principle is that a court’s decisions apply retroactively to all cases still pending before the courts.” 646 F.3d at 690 ; see also Harper, 509 U.S. at 97 , 113 S.Ct. 2510 . Furthermore, we continue to adhere to the Supreme Court’s admonishment that if a decision is not to be given retroactive effect, its prospective-only application should be announced in the opinion itself. In Harper , the Supreme Court stated:

509 U.S. at 97-98 , 113 S.Ct. 2510 (quoting Beam, 501 U.S. at 539 , 111 S.Ct. 2439 ); see also United States v. 20832 Big Rock Drive, 51 F.3d 1402, 1406 (9th Cir.1995) (holding that “it is now clear that a new rule of law applies retroactively to civil cases on direct review or those not yet final if it is applied to the parties in the case in which it is announced”).

Thus, Duran Gonzales II would have retroactive application even if it did not address retroactivity. But it was not silent. The final paragraph held that “plaintiffs as a matter of law are not eligible to adjust their status because they are ineligible to receive 1-212 waivers.” Duran Gonzales II, 508 F.3d at 1242 . Because this court applied its holding in Duran Gonzales II to the parties before it, the ruling is retroactive.

Moreover, Plaintiffs have not cited any authority, nor have we found any, that would allow a district court to interpret, in the first instance, whether a Ninth Circuit opinion applied prospectively only or retroactively. Rather, the general rule is that:

Matter of Beverly Hills Bancorp, 752 F.2d 1334, 1337 (9th Cir.1984). Here, the district court properly determined that Duran Gonzales II applied retroactively to Plaintiffs.

B. This Panel May Not Now Rule That Duran Gonzales II Applies Only Prospectively And Not Retroactively.

Even if Duran Gonzales II could be read as not clearly holding that it had retroactive application (by applying its ruling to the parties before it), the fact that Duran Gonzales II did not otherwise “reserve the question whether its holding should be applied to the parties before it” would be dispositive. See Harper, 509 U.S. at 97-98 , 113 S.Ct. 2510 . It is now too late to apply Duran Gonzales II prospectively only. Since its announcement in 2007, the “normal rule of retroactive application” has applied and presumably Duran Gonzales II has been routinely applied by district courts and the BIA in other cases. Indeed, Duran Gonzales II has been cited approvingly by two other circuit courts. See Delgado v. Mukasey, 516 F.3d 65, 73 (2d Cir.2008), and Gonzalez-Balderas v. Holder, 597 F.3d 869, 870 (7th Cir.2010).

Furthermore, our opinion in MoralesIzquierdo, 600 F.3d 1076 , held that Duran Gonzales II applies retroactively, and we are bound by that decision. See Santama ria v. Horsley, 110 F.3d 1352, 1355 (9th Cir.1997) (“It is settled law that one three-judge panel of this court cannot ordinarily reconsider or overrule the decision of a prior panel.”). The Morales-Izquierdo court fully considered retroactivity. It commented that “[wjhatever the adjudicative history preceding Gonzales, and whatever the tools used in Gonzales to interpret the statute, a statute can have only one meaning, and Gonzales tells us what that meaning is.” Morales-Izquierdo, 600 F.3d at 1089 . The court concluded that “Gonzales is ultimately a judicial interpretation of a federal statute,” and despite Morales’s “sense of unfairness engendered by the retrospective application of a new judicial interpretation of an old statute[,] ... when a court interprets a statute, even an ambiguous one, and even when that interpretation conflicts with the court’s own prior interpretation, the new interpretation is treated as the statute’s one-and-only meaning.” Id. at 1090 (citing Griffith v. Kentucky, 479 U.S. 314, 323 , 107 S.Ct. 708 , 93 L.Ed.2d 649 (1987)). Accordingly, we held that Duran Gonzales II applied to Morales and “to all cases currently on direct review.” Morales-Izquierdo, 600 F.3d at 1092 .

Plaintiffs attempt to distinguish Morales-Izquierdo on the ground that Morales’s reliance on Perez-Gonzalez was not as reasonable as Plaintiffs’ reliance. The argument is not well taken. In Nunez-Reyes , we reaffirmed that “a court announcing a new rule of law must decide between pure prospectivity and full retro-activity,” and, citing Justice Souter’s plurality opinion in James B. Beam Distilling Co., 501 U.S. at 537-38 , 111 S.Ct. 2439 , confirmed that weighing “the equities on a case-by-case basis[] is foreclosed.” 646 F.3d at 690-91 . Thus, Morales-Izquierdo’s holding of retroactivity cannot be distinguished on the ground that Morales’s alleged reliance on Perez-Gonzalez was somehow less serious or reasonable than Plaintiffs’ reliance on the opinion.

Duran Gonzales II specifically applied its ruling to the petitioners before it and in Morales-Izquierdo, a separate three-judge panel confirmed that Duran Gonzales II applies retroactively; we are bound by these decisions. It follows that the holding in Duran Gonzales II that “plaintiffs as a matter of law are not eligible to adjust their status because they are ineligible to receive 1-212 waivers,” 508 F.3d at 1242 , applies to Plaintiffs and undermines their legal action.

Finally, because we determine that we cannot retroactively revise Duran Gonzales II to have only prospective application, we need not determine whether we would limit Duran Gonzales II to prospective application if we could. We note, however, that the situation in Nunez-Reyes is distinct from that presented in this appeal. In Nunez-Reyes , the petitioner and others similarly situated waived constitutional rights in reliance on our pri- or opinion. We stressed that it “would be manifestly unfair effectively to hoodwink aliens into waiving their constitutional rights on the promise of no legal consequences and, then, to hold retroactively that their convictions actually carried with them the particularly severe penalty of removal.” Nunez-Reyes, 646 F.3d at 694 (internal quotation marks omitted). Here, the Plaintiffs, in relying on Perez-Gonzalez , did not waive any constitutional right, although they did disclose to the government their illegal presence within the country. Whatever weight might be given to such reliance, it is considerably less than that given to the waiver of a constitutional right.

V

Plaintiffs’ request for relief from the retroactive application of Duran Gonzales II to their applications for adjustment of status must be denied because: (1) Duran Gonzales II itself applied its rulings to the Plaintiffs, thus giving the opinion retroactive application; and (2) another three-judge panel has reaffirmed that Duran Gonzales II has retroactive application. Morales-Izquierdo, 600 F.3d at 1092 . The district court properly determined that Duran Gonzales II applies retroactively and that, accordingly, Plaintiffs are “ineligible to receive 1-212 waivers.” Duran Gonzales II, 508 F.3d at 1242 . The district court’s orders denying Plaintiffs’ motions to amend class certification and to file an amended complaint, and dismissing this action, are AFFIRMED.

. The BIA reasoned: Perez-Gonzalez allows an alien to obtain a section 212(a)(9)(C)(ii) waiver nunc pro tunc even though such a waiver would have been unavailable to him had he sought it prospectively, thereby placing him in a better position by asking forgiveness than he would have been in had he asked permission. Such an interpretation contradicts the clear language of section 212(a)(9)(C)(ii) and the legislative policy underlying section 212(a)(9)(C) generally. We find that the more reasonable interpretation of the statutory framework discussed above is that an alien may not obtain a waiver of the section 212(a)(9)(C)(i) ground of inadmissibility, retroactively or prospectively, without regard to the 10-year limitation set forth at section 212(a)(9)(C)(ii). In re Torres-Garcia, 23 I. & N. Dec. at 876 . . Citing Harper v. Virginia Department of Taxation, 509 U.S. 86 , 113 S.Ct. 2510 , 125 L.Ed.2d 74 (1993), the district court reasoned that the "Ninth Circuit’s silence on the retro-activity of its decision requires this Court to assume that it carries full retrospective effect.” . We described Morales’s argument as follows: According to Morales, our decision in Gonzales does not establish a definitive interpretation of what the INA has always meant, but rather that Congress has created a "gap” in the INA and delegated authority to DHS to fill in the gap. Morales argues, then, that the question is not whether our decision in Gonzales applies retroactively, but rather whether the BIA's interpretation of the INA in Torres-Garcia applies retroactively, because it is Torres-Garcia that gives content to the gap in 8 U.S.C. § 1182 (a)(9)(C). And unlike a judicial decision, a decision made by an administrative agency acting in an adjudicatory capacity does not necessarily apply retroactively. See, e.g., Montgomery Ward & Co., Inc. v. FTC, 691 F.2d 1322, 1328 (9th Cir.1982) (“[W]hen a new problem is presented to an administrative agency, the agency may act through adjudication to clarify an uncertain area of the law, so long as the retroactive impact of the clarification is not excessive or unwarranted.”). Therefore, Morales contends, we must conduct a multi-factor retroactivity analysis to determine whether or not the rule of Tones-Garcia applies to him. See, e.g., Miguel-Miguel v. Gonzales, 500 F.3d 941, 951 (9th Cir.2007). Morales-Izquierdo, 600 F.3d at 1088 . . The panel explained that "[f]or those aliens convicted before the publication date of this decision, Lujan-Armendariz applies. For those aliens convicted after the publication date of this decision, Lujan-Armendariz is overruled.” 646 F.3d at 694 . . The panel explained: Relevant here, we think it is a reasonable assumption that Congress intended adverse immigration consequences only for those who were convicted either after the exercise of their constitutional rights, such as the right to trial, or after an informed waiver of those constitutional rights. As discussed above, many alien defendants fell into neither category. Instead, they pleaded guilty and waived their constitutional rights with a wholly uninformed understanding of the consequences of their plea. Contrary to their understanding that there would be no immigration consequences, the actual consequence is the severe penalty of removal. Nothing in the statute or its history, purpose, or effect suggests that Congress intended adverse immigration consequences for those whose waiver of constitutional rights turned out to be so ill-informed. Indeed, the Supreme Court has instructed that such a gross misunderstanding of the immigration consequences of a plea, when caused by incompetent counsel, rises to the level of a constitutional violation. Padilla [v. Kentucky], [- U.S. -] 130 S.Ct. [1473] at 1486-87 [ 176 L.Ed.2d 284 (2010)]. Nunez-Reyes, 646 F.3d at 694 (emphases in original). . This determination also governs Plaintiffs' motions to file an amended complaint and to amend their class certification because neither amendment could overcome or circumvent the legal determinations in Duran Gonzales II. . The Supreme Court’s opinion in Fernandez-Vargas v. Gonzales, 548 U.S. 30 , 126 S.Ct. 2422 , 165 L.Ed.2d 323 (2006), tends to undercut the weight accorded this reliance. The Court noted: it is the conduct of remaining in the country after entry that is the predicate action; the statute applies to stop an indefinitely continuing violation that the alien himself could end at any time by voluntarily leaving the country. It is therefore the alien’s choice to continue his illegal presence, after illegal reentry and after the effective date of the new law, that subjects him to the new and less generous legal regime, not a past act that he is helpless to undo up to the moment the Government finds him out. Id. at 44 , 126 S.Ct. 2422 .
