OPINION
Aurеlio 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,
The government appealed, and in
Duran Gonzales v. Department of Homeland Security,
Accordingly, we vacated the district court’s injunction and remanded the matter. Our оpinion 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
*933
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.,
I
Plaintiffs are individuals who are not citizens of thе 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 immediatеly available immigrant visa, and (2) paid an application fee five times the usual fee.”
Duran Gonzales II,
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 аpply for any relief.”
Duran Gonzales II,
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
an alien seeking admission more than 10 years after the date of the alien’s last departure from the United States if, pri- or to the alien’s reembarkation at a place outside the United States or attempt to be readmitted from a foreign сontiguous territory, the Secretary of Homeland Security has consented to the alien’s reapplying for admission.
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,
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.
*934 II
On appeal, we were constrained by the Supreme Court’s opinion in
Brand X,
by declining to adhere to the plain language of the inadmissibility provision and instead falling back on the regulations, Perez-Gonzalez did not find the inadmissibility provision, nor the statutory schеme, to be unambiguous. Accordingly, we are not bound by Perez-Gonzalez and must defer to In re Torres-Garcia if its interpretation of the governing statute is reasonable.
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.” 1 Id. at 1241. We determined that the BIA’s decision was “clearly reasonable” and entitlеd to Chevron deference under Brand X. Id. at 1242.
The final paragraph in Duran Gonzales II states:
we vacate the district court’s order because we hold today that we are bound by the BIA’s interpretation of the applicable statutes in In re Torres-Garcia, even though that interpretation differs from our prior interpretation in Perez-Gonzalez. Pursuant 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.... The case is remanded for further proceedings consistent with this opinion.
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.
*935 The district court rejected Plaintiffs’ arguments, denied their motiоn 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.” 2 The court reasoned that allowing Plaintiffs to amend their complaint or to amend their class certification would be futile because neither аmendment 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,
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.
Morales filed several petitions seeking review of these actions. We granted his initial petition for review of the reinstatement order.
Morales-Izquierdo v. Ashcroft,
Morales argues that еven though he did not file an application for a Form 1-212 waiver when he applied for adjustment of status in 2001, errors of the INS entitle him to have his subsequently-filed Form 1-212 waiver application treated as if it were timely filed in 2001. Morales has a problem, however: The current law of our circuit provides that a Form 1-212 waiver, even if granted, does not cure the inadmissibility of an alien who reenters the United States without inspection after a prior removal. Gonzales,508 F.3d at 1242 ; see also 8 U.S.C. § 1182(a)(9)(C)(ii). Morales concedes that if the holding in Gonzales appliеs to him, he cannot cure the deficiency in his adjustment-of-status application. Morales nonetheless argues that Gonzales — decided six years after Morales filed his first adjustment-of-status application and four years after his second — cannot be applied retroactively to make him ineligible for a waiver of inadmissibility. He argues that under the law that was established in our circuit prior to Gonzales, a Form 1-212 waiver could cure his inadmissibility, that he *936 was eligible for such a waiver, and that our prior law should apply to him.
Morales-Izquierdo,
In rejecting Morales’s argument, we started with the stаndard 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.,
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. 3 We held:
Yet, whatever disputes on theory of statutory interpretation may be sparked, we conclude that the interpretation of the INA that we adopted in Gonzales renders Morales ineligible for a Form 1-212 waiver. True, Gonzales declared the INA ambiguous and deferred to the BIA’s interpretation of the INA for the purpose of determining what the statute means. But statutory ambiguity alone has never been sufficiеnt to render judicial interpretation of a statute non-retroactive. Gonzales is still a judicial decision interpreting a statute, and courts remain “the final authority on issues of statutory construction.” Chevron,467 U.S. at 843 n. 9,104 S.Ct. 2778 ,.... Under Gonzales, 8 U.S.C. § 1182(a)(9)(C)(ii) renders aliens in Morales’s position ineligible for waiver of the ten-year bar. See Gonzales,508 F.3d at 1242 . That rule is dispositive and wholly scuttles the argument of Morales. Whatever 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,
Our reasoning led us to reject Morales’s request for “а 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 *937 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 сounts 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,
The en banc panel first overruled our prior decision in
Lujan-Armendariz v. INS,
The panel, however, determined that this holding “will apply only prospectively.”
4
Id.
at 694. The panel recognized that the “default principle is that a court’s decisions apply rеtroactively 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,
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,
Those aliens were assured that, after completion of drug treatment, there would be absolutely no legal сonsequences. Their waiver of their constitutional rights was in reliance on Lujanr-Armendariz. In these circumstances, we easily conclude that the third Chevron Oil factor is met: our decision “could produce substantial inequitable results if applied retroactively.” Chevron Oil,404 U.S. at 107 , 92 S.Ct. *938 349.... 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, Padilla,130 S.Ct. at 1481 ....
Nunez-Reyes,
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,
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.”
*939 When this Court does not “reserve the question whether its holding should be applied to the parties before it,” however, an opinion announcing a rule of federal law “is properly understoоd to have followed the normal rule of retroactive application” and must be “read to hold ... that its rule should apply retroactively to the litigants then before the Court.”
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,
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:
On remand, a trial court may not deviate from the mandate of an appellate court. As we have stated earliеr, “[w]hen a case has been decided by an appellate court and remanded, the court to which it is remanded must proceed in accordance with the mandate and such law of the case as was established by the appellate court.” Firth v. United States,554 F.2d 990 , 993 (9th Cir.1977); .... The Supreme Court long ago emphasized that when acting under an appellate court’s mandate, an inferior court “cannot vary it, or examine it for any other purpose than execution; or give any other or further relief; or review it, even for apparent error, upon any matter decided upon appeal; or intermeddle with it, further than to settle so much as has been remanded.” In re Sanford Fork & Tool Co.,160 U.S. 247 , 255,16 S.Ct. 291 ,40 L.Ed. 414 (1895).
Matter of Beverly Hills Bancorp,
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,
Furthermore, our opinion in
MoralesIzquierdo,
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.,
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,”
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,
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,
Notes
. 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,
. 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 dеcision, 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,
Morales-Izquierdo,
. 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.”
. 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 wаiver 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 [
Nunez-Reyes,
. 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,
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.
