Respondents-Appellants John Ashcroft, et al. (“the Attorney General”) appeal a decision of the district court granting Petitioner-Appellee Mazen Al Najjar’s request for habeas corpus relief in connection with his bond redetermination proceedings. In an order dated May 31, 2000, the district court ruled that the government could not detain Al Najjar pending judicial review of the BIA’s order of deportation on the basis of undisclosed, classified information linking him to the Palestinian Islamic Jihad (“PIJ”), a terrorist organization.
See Al Najjar v. Reno,
I.
Understanding the circumstances of this case requires a discussion of two separate, yet largely concurrent, legal actions involving Al Najjar. The first action is the government’s effort to remove Al Najjar from the United States due to the expiration of his status as a legal alien. The second action, which is the subject of this appeal, is Al Najjar’s bid to be released from detention on bond during the pen-dency of his deportation proceedings. In the end, it is the recent and final completion of the first action that renders the instant case unambiguously moot.
*1333
Al Najjar was born in Gaza in 1957 and moved with his family to Saudi Arabia one year later. After thirteen years there, he moved to Egypt, where he completed high school and eventually received a bachelor’s degree in 1979. From 1979 to 1981, he worked in the United Arab Emirates (“UAE”) on a temporary work visa. In 1981, Al Najjar first entered the United States on a Palestinian refugee travel document issued by the Egyptian government. Aside from a brief trip abroad in 1984, Al Najjar has remained in this country since that time. After obtaining authorization from the Immigration and Naturalization Service (“INS”) to stay in the United States for the duration оf his non-immigrant student status, Al Najjar pursued graduate degrees in engineering in North Carolina and at the University of South Florida (“USF”) in Tampa, earning a doctorate in 1994. In addition to his engineering work, Al Najjar helped to found at USF the World and Islam Studies Enterprise (“WISE”), described by this Court in the related case as “a think-tank ostensibly committed to educating the public about Islamic issues through research, publishing, and seminars.”
The first legal action against Al Najjar (the government’s effort to deport him) commenced on April 19, 1985, when the INS issued an order to show cause under 8 U.S.C. § 1251(a)(9) (1984), alleging that Al Najjar had failed to maintain the conditions of his nonimmigrant status by providing untruthful informatiоn to the INS. The basis of the allegation was a claim by Al Najjar’s first wife that she had participated in a sham marriage to allow him to obtain a green card. The INS later supplemented the order to show cause by charging that Al Najjar had not maintained the conditions of his nonimmigrant status under the Immigration and Nationality Act (“INA”). On June 4, 1986, the case against Al Najjar was closed when he failed to appear at an administrative hearing. Al Najjar asked the INS to re-open the hearing once he received notice of it a few weeks later, but he received no response.
After a decade had passed, the INS rescheduled Al Najjar’s case for a deportation hearing on February 8, 1996. Those proceedings were consolidated with deportation proceedings for his wife, Fe-daa. At the hearing, Al Najjar conceded his deportability on the ground that he had overstayed his nonimmigrant student visa status, but he asked for relief from deportation, including asylum, withholding of removal, and suspension. In an effort to show that Al Najjar should not be given discretionary relief, the INS produced at the administrative hearing evidence purportedly linking Al Najjar and WISE to the PIJ, a known terrorist group, and various individuals who have supported and engaged in terrorism in the Middle East. On May 13, 1997, an immigration judge (“IJ”) found Al Najjar deportable and denied his application for relief. The IJ designated the UAE as his country of deportation, and Al Najjar appealed to the Board of Immigration Appeals (“BIA”).
Six days after the IJ’s ruling, federal agents arrested Al Najjar on the basis of classified information that he was connected to Middle Eastern terrorist organizations and detained him without bond on the ground that he posed a threat to national security. The second relevant legal action then commenced when, pursuant to 8 C.F.R. § 242.2(d) (1995), Al Najjar requested a redetermination of his custody status. The IJ conducted a two-part hearing. The first part of the hearing was public and the second consisted of an ex parte review of classified information. The IJ then re-opened the public hearing to allow Al Najjar to rebut an unclassified summary of the confidential material. *1334 The summary stated that “[t]his Court was provided with information as to the association of [Al Najjar] with the Palestinian Islamic Jihad.” Al Najjar’s attorneys then called witnesses .to rebut the allegation in this summary. On June 23, 1997, the IJ held that Al Najjar should remain detained without bond because he “is associated with a terrorist organization known as the Palestinian Islamic Jihad.” Al Najjar appealed the bond decision to the BIA, arguing that the consideration of classified evidence in ex parte proceedings violated various statutory and constitutional rights. On September 15, 1997, the BIA affirmed the IJ’s bond decision.
Two years later, on October 26, 1999, a different BIA panel affirmed the May 1997 IJ decision in the first action, ordering the deportation of Al Najjar and his wife. The Al Najjars then petitioned this Court for judicial review of their orders of deportation issued by the BIA. At the beginning of that judicial review, on December 16, 1999, a panel of this Court granted the Al Najjars’ unopposed motions to stay deportation pending completion of their appeals to this Court.
After his deportation order was stayed and while his petition for judicial review of his deportation order was pending, Al Naj-jar filed on December 22, 1999 a petition for a writ of habeas corpus in the United States District Court for the Southern District of Florida pursuant to 28 U.S.C. § 2241, seeking his immediate release from custody pending the conclusion of the deportation proceedings. Like the appeal to the BIA, the habeas petition alleged that the consideration of classified material was barred by both the INA and the due process clause of the Fifth Amendment of the United States Constitution. Thе petition also claimed that Al Najjar was being punished on the basis of his political associations in violation of the First and Fifth Amendments.
On May 31, 2000, with the direct appeal of the merits of his deportation order still pending, the district court granted in part Al Najjar’s petition for habeas relief. In its opinion, the district court framed the question in the case as “whether Petitioner has been denied the right to a fundamentally fair bond redetermination hearing pending the final determination of his deportation proceedings.”
As a remedy, the district court remanded the matter back to the IJ to make an initial determination of Al Najjar’s entitlement to bond based solely on the public record. If the public evidence did not support detention, the government would be allowed to introduce the classified evidence in a way that afforded Al Najjar “access to the decisive evidence to the fullest extent possible, without jeopardizing legitimately raised national security interests.” Id. at 1358 (quotations omitted). The government appealed to this Court and Al Najjаr filed a cross-appeal, primarily challenging the district court’s conclusion that the INA authorized the use of confidential information.
*1335 On remand, the IJ concluded after the first phase of the hearing that the public information failed to support detention, and, in the second phase, the government presented only a one-page “unclassified summary” and a sixteen-page “unclassified extract.” Finding the new evidence to be insufficient and conclusory, the IJ ordered Al Najjar released on $8,000 bond. After three years and seven months in custody, Al Najjar was released pursuant to an order signed by the Attorney General on December 15, 2000. The INS initially appealed the bond decision to the BIA, but the appeal was dismissed as withdrawn on August 3, 2001.
On July 18, 2001, before the appeal of the bond decision to the BIA was withdrawn, another panel of this Court issued a final merits decision in the first action, affirming the BIA’s deportation order for Mazen and Fedaa Al Najjar. The panel found substantial evidentiary and legal support for the BIA’s conclusions that the Al Najjars were ineligible for asylum on the basis of a fear of persecution and that they could not meet the great burden necessary for receiving withholding of deportation.

The Court denied Al Najjar’s motion to reconsider its decision and his motion for rehearing en banc on October 25, 2001. On November 13, 2001, the panel also denied Al Najjar’s motion to stay issuance of the mandate pending a petition for a writ of certiorari to the Supreme Court. The mandate issued on the same day.

Article III of the Constitution limits the jurisdiction of the federal courts to the consideration of “Cases” and “Controversies.” U.S. Const, art. Ill, § 2. In turn, the “case or controversy” constraint imposes on federal courts a “dual limitation” known as “justiciability.”
United States v. Florida Azalea Specialists,
The doctrine of mootness derives directly from the case-or-controversy limitation because “an action that is moot cannot be characterized as an active case or controversy.”
Adler v. Duval County Sch. Bd.,
Although there is an exception to the mootness doctrine when the action being challenged by the lawsuit is capable of being repeated
and
evading review, this exception is “narrow,”
Dow Jones & Co. v. Kaye,
III.
As in virtually every recent immigration case, it is necessary to begin the discussion by clarifying what law governs our analysis. In this case, that task is not difficult because another panel of this Court in the related first action against A1 Najjar has already concluded that the transitional rules, enacted by the Illegal Immigration Reform and Immigrant Responsibility Act of 1996 (“IIRIRA”), govern A1 Najjar’s deportation proceedings.
See
The circumstances of this case have changed dramatically since Al Najjar began his quest for bond. When a panel of this Court issued a mandate affirming Al Najjar’s deportation on November 13, 2001, this terminated the Dеcember 16, 1999 stay of Al Najjar’s deportation and also undoubtedly resulted in a final order of deportation. Plainly, the final order of deportation gives the Attorney General unambiguous authority under controlling law to take Al Najjar into custody now without any regard to confidential information allegedly linking him to terrorist organizations. Therefore, the question addressed by the district court of whether the classified evidence could be considered in determining bond is moot, necessitating the va-catur of the district court’s order and the bond granted by the IJ pursuant to that order.
As an initial matter, the November 13th mandate of this Court constitutеs a final order of deportation for Al Najjar. Under the federal regulations governing deportation proceedings commenced prior to April 1, 1997, an order of deportation is “final and subject to execution” on the date when any of the following occurs: (1) a grant of voluntary departure expires; (2) an IJ enters an order of deportation without granting voluntary departure or other relief and the alien waives the right to appeal; (3) the BIA enters an order of deportation on appeal, without granting voluntary departure or other relief; or (4) a federal district or appellate court affirms an administrative order of deportation in a petition for review or habeas corpus action. See 8 C.F.R. § 241.33(a) (2001) (emphasis added). 3 There can be no question that the panel’s decision in the related case affirmed the BIA’s final administrative order of deportation for Al Najjar, and that order was final and executable as soon as the mandate issued. 4
Moreover, the fact that this Court previously granted a stay of deportation does not affect the finality of the order now that the panel has rejected Al Najjar’s merits appeal in the related case. The stay was valid only pending a final detеr-
*1338
initiation by the appellate panel. As this Court’s predecessor has explained, the issuance of a mandate in a case automatically terminates a stay entered pending resolution of the appeal.
See Texas & New Orleans R.R. v. B’hood of R.R. Trainmen,
Now that the mandate has issued, the stay has terminated, and a final order has been entered, the government has the plain and unmistakable power to detain Al Najjar in order to exеcute the BIA’s deportation order. Notably, this basis for detention is completely unrelated to any allegation that Al Najjar poses a threat to the national security due to his connections to the PIJ and wholly independent of the review of any classified information. See 8 U.S.C. § 1252(c) (1995); 8 U.S.C. § 1231(a)(2) (2001); 8 C.F.R. § 241.33(a) (2001). While it is possible that issues may arise later regarding how long the Attorney General can detain Al Najjar in furtherance of the execution of a final deportation order, it remains clear that the Attorney General now has the authority to detain Al Najjar without regard to any classified information. 7
Indeed, the federal regulation gоverning detention emphasizes that aliens subject to deportation as a result of proceedings commenced before April 1, 1997 should generally be taken into custody and detained, with the discretion to release them entrusted to the INS District Director: “Except in the exercise of discretion by the *1339 district director, and for such reasons as are set forth in § 212.5(b) of this chapter, once an order of deportation becomes final, an alien shall be taken into custody and the order shall be executed.” 8 C.F.R. § 241.33(a) (2001). We reiterate that, under the statute and regulations governing post-final order detention, the Attorney General, acting through the District Director, has the authority to take Al Najjar into custody without relying in any way on the allegation that Al Najjar presents a national security threat.
Because the Attorney General now has the unfettered power to detain Al Najjar, it is utterly unnecessary to take up the question addressed by the district court — whether classified information can be used to deny bond in a pre-final order detention hearing. In fact, the “case or controversy” requirement of Article III unambiguously
forbids
us from considering the question in the absence of a live dispute. Any opinion on the matter would be purely advisory.
See, e.g., Florida Ass’n of Rehab. Facilities,
The fоrmer Fifth Circuit recognized this basic principle in binding precedent fifty years ago, when, in one of the first cases decided under the INA of 1952,
8
it dismissed as moot an alien’s habeas corpus petition seeking release on bond after a final order of deportation was entered: “We think it clear ... that the deportation order is now final; that the question raised by his appeal, whether the court erred in denying him bond pending the deportation proceedings, has become moot; and that the appeal should be dismissed.”
United States ex rel. Spinella v. Savoretti,
To the extent either party suggests that the appeal is not yet moot because there exists at least the possibility that the question of classified material could arise again in the future, we remain unpersuaded. In essence, this contention amounts to an argument that we should apply the mootness doctrine’s narrow exception for controversies that are capable of repetition yet evading review. This argument fails because the controversy at issue in the district court’s opinion cannot arise again necessarily, as Al Najjar is now, and will be, subject to a final order of deportation.
Once a final order of deportation is entered, an alien who may seek bond must do so through a process entirely distinct from that used before a final order is in place. While bond proceedings before a final order are handled by an IJ in adversary proceedings with appeal to the BIA, see 8 C.F.R. § 242.2(d) (1995), bond after the entry of a final order is obtained solely at the discretion of the District Director.
See
8 C.F.R. § 241.33(a) (2001);
see also In re Valles-Perez,
21 I.
&
N. Dec. 769, 772,
The narrow exception for actions that are capable of repetition yet evading review applies only in the exceptional circumstance in which the same controversy will recur and there will be inadequate time to litigate it prior to its cеssation.
See, e.g., Sierra Club,
When a case becomes moot on appeal, under controlling law the Court of Appeals must not only dismiss the case, but also vacate the district court’s order. This practice “clears the path for future relitigation of the issues between the parties and eliminates a judgment, review of which was prevented through happenstance.”
Atlanta Gas Light Co. v. Fed. Energy Regulatory Comm’n,
Without jurisdiction, we are barred from reaching the merits of the Attorney General’s appeal and A1 Najjar’s cross-appeal. Our decision does not detract from the recognition that this case, if live, would raise a number of extremely significant issues involving immigration law and procedure, national security and classified information, and due process of law. Fоr example, the government says that the district court erred in declining to follow this court’s decision in
United States ex rel. Barbour v. INS,
IV.
In sum, the government’s appeal and A1 Najjar’s cross-appeal must be and are DISMISSED as moot, and the order of the district court and the resulting bond decision of the Immigration Judge are hereby VACATED.
Notes
. As this Court observed in the related first action: "Mazen’s deportation proceedings commenced in 1985 when the INS issued an OSC against him.... Final orders of deportation were entered against Mazen and Fedaa in October 1999 when the BIA, by written opinion, affirmed the IJ’s decision denying relief under the INA.
See
8 C.F.R. § 241.31 (2001) (explaining that an order of deportation 'shall become final upon dismissal of an appeal by the Boаrd of Immigration Appeals,’ among other things). Thus, the Al Najjars are subject to the transitional rules, not the new 'permanent rules.’ ”
In addition, this Court has held that § 2241 habeas review remains available for aliens whose deportation proceedings are governed by the transitional rules of IIRIRA.
See Alanis-Bustamante v. Reno,
. IIRIRA eliminated the distinction between "deportation” and "exclusion,” placing both procedures under the heading "removal.” Under the old law, Al Najjar was subject to "deportation” since he had initially been admitted lawfully to the United States. Because the instant case is proceeding under IIRIRA's transitional rules, we continue to use the old nomenclature and refer to the proceedings against Al Najjar as "deportation,” rather than "removal.”
. Although put into effect pursuant to IIRIRA, this regulation was explicitly made retroactive to apply to all proceedings commenced before April 1, 1997. See 8 C.F.R. § 241.30 ("Sub-part C of 8 CFR part 241 applies to deportation proceedings commenced prior to April 1, 1997.”).
. The government submits the district court erred in failing to recognize that the BIA’s affirmance of the immigration judge’s deportation order was already a final order of deportation under immigration law that triggered the application of regulations which authorized detention of Al Najjar, vested jurisdiction over his custody status in the INS District Director, and afforded additional deference to the Attorney General's parole decisions,
see
8 C.F.R. §§ 212.5, 236.1(d), 241.33(a). The government also suggests that the framework the district court used to analyze Al Najjar's due process rights was inconsistent with the district court's earlier recognition in its own opinion that, under 8 U.S.C. § 1101(a)(47)(B), Al Najjar was subject to a final deportation order when the BIA affirmed his deportation order on October 26, 1999.
See
. In
Bonner v. City of Prichard,
. In this regard, we also observe that section 309(c)(1) of IIRIRA provided that “fsjubject to the succeeding provisions of this subsection, in the case of an alien who is in exclusion or deportation proceedings before the title III-A effective date [April 1, 1997](A) the amendments made by- this subtitle shall not аpply, and (B) the proceedings (including judicial review thereof) shall continue to be conducted without regard to such amendments.” 8 U.S.C. § 1101 note (emphasis added). However, the succeeding provision in § 309(c)(4)(F), created an exception to this rule for transitional changes in judicial review applicable here, directing that "service of the petition for review shall not stay the deportation of an alien pending the court's decision on the petition, unless the court orders otherwise.” Id. Thus, under IIRIRA's transitional rules in § 309(c)(4)(F), as well as IIRIRA's permanent rules in 8 U.S.C. § 1252(b)(3)(B), the service of a petition for judicial review does not stay thе execution of a deportation order, which is why Al Najjar needed to ask this Court to stay the BIA's deportation order.
.This authority is granted to the Attorney General under both pre and post-IIRIRA law, and this case, involving a bond redetermination prior to a final and executable deportation order, plainly does not present the question of how long the Attorney General can detain an alien in order to execute a final deportation order. Thus, we do not address that issue here.
. Although the Fifth Circuit's opinion does not discuss the background of the case, a subsequent opinion from the Southern District of New York filed after Spinella’s deportation described the history of his case and explained that he was deported under the INA of 1952.
