OPINION OF THE COURT
In this case, we reconsider a petition for review which was first filed on May 12,1995, by Eleazar Jose Morel, a native and citizen of the Dominican Republic. The Immigration and Naturalization Service (INS) asks us
*250
to set aside our original opinion in this case in which we granted Morel’s petition- challenging the Board of Immigration Appeals’ .(BIA) construction of § 212(c) of the Immigration and Nationality Act (INA), 8 U.S.C. § 1182(c).
See Morel v. INS,
Although the limited factual record has already been set out in our previous opinion, we nonetheless provide a detailed procedural history because of the significance of the timing of the events leading up to this rehearing. . These events were set in motion when Morel was arrested in New Jersey on August 24,1991, and charged with possession of a controlled dangerous substance and possession of a controlled dangerous substance within 1000 feet of a school. On January 6, 1993, Morel was sentenced to four years in a New Jersey correctional facility, after pleading guilty to the first possession charge. 1
While serving his sentence, Morel was served with an Order to Show Cause and Notice of Hearing by the INS. Upon completion of'his sentence and his transfer to an INS detention facility in Oakdale, Louisiana, Morel was provided a hearing before an immigration judge. At the hearing held on January 17, 1994, Morel conceded that he had been convicted of a deportable offense, but sought discretionary relief pursuant to INA § 212(c). The immigration judge denied Morel’s request, finding that he had accumulated insufficient residency to be eligible for discretionary relief and ordered him deported to the Dominican Republic. On April 10, 1995, the BIA affirmed the order and dismissed Morel’s appeal.
On May 12, 1995, Morel filed a petition for review in this Court. We ordered argument of the case on March 25, 1996. On July 26, 1996, a majority of this panel issued an opinion in which we concluded that the INS had erred in construing INA § 212(c) to impose a requirement of seven consecutive years domicile after he was admitted to the United States as a lawful permanent resident- and in interpreting § 212(c) not to allow for the crediting of Morel’s accumulated residency for the time that his mother proceeded him in the United States.

Morel,
We remanded Morel’s case to the BIA for further proceedings. However, prior to any further action being taken before the agency, the INS submitted a Petition for Panel Rehearing in which the agency contended that AEDPA’s passage on April 24, 1996, had divested us of jurisdiction to entertain Morel’s petition for review. We ordered additional briefing and granted reargument to address this serious jurisdictional concern.
We agree that AEDPA divests this Court of jurisdiction. 3 In the case of *251 aliens convicted of certain criminal offenses, AEDPA § 440(a) removes from us jurisdiction to review a claim of legal error in deportation proceedings. 4 Morel does not dispute that he was convicted of a deportable criminal offense covered in INA § 241(a)(2)(B)(I), 8 U.S.C. § 1251(a)(2)(B)(I). Thus, we conclude that AEDPA § 440(a) denies Morel the right to obtain review by an Article III court. 5 The subsequent adoption by Congress of the Illegal Immigration Reform and Immigrant Responsibility Act of 1996 (IIRIRA), Div. C of Pub.L. 104-208, 110 Stat. 3009 (1996) on September 30, 1996, further restructuring the deportation process, does not affect the outcome of this ease.
Furthermore, although Morel asserts to the contrary, we do not see any deprivation of his rights which is of constitutional proporr tion. The INS concedes that § 440(a) does not preclude Article III court review of claims of “substantial Constitutional error.”
Resp. Supp. Br.
at 20. Morel’s claim here is not such a claim—he has sought review of a question of law as we set out in our prior opinion,
see Morel v. INS,
To conclude, because Congress has divested us of jurisdiction to review matters falling within the purview of AEDPA § 440(a), we will vacate our prior opinion in this matter,
see Morel v. INS,
Notes
. The charge of possession of a controlled dangerous substance within a 1000 feet of a school was dismissed, ostensibly as part of a plea agreement.
. Judge Greenberg filed a dissenting opinion.
See Morel,
. Although the enactment of AEDPA pre-dated the filing of our original opinion on July 26, 1996, the INS did not alert us to the possible defect in our jurisdiction until September 9, 1996. The government now candidly confesses - that the failure to raise the issue sooner was an oversight on its part.
This case. is unusually postured in that no jurisdictional challenge was advanced until after our merits opinion was filed. There is, however, no suggestion that we should not examine our jurisdiction for this reason. Indeed, we are obliged to investigate into our competence to hear a case regardless of the action or inaction of the parties:
[N]o action of the parties can confer subject-matter jurisdiction upon a federal court. Thus, the consent of the parties is irrelevant, principles of estoppel do not apply, and a party does not waive the requirement by failing to challenge jurisdiction early in the proceedings.... [A] court, including an appellate court, will raise lack of subject-matter jurisdiction on its own motion. “|T|he rule, springing from the nature and limits of the judicial power of the United States is inflexible and without exception, which requires this court, of its own motion, to deny its jurisdiction, and, in the exercise of its appellate power, that of all other courts of *251 the United States, in all cases where such jurisdiction does not affirmatively appear in the record.”
Insurance Corp. of Ireland, Ltd. v. Compagnie des Bauxites de Guinee,
This obligation applies with equal force to claims that we are without jurisdiction because the action has become moot.
North Carolina v. Rice,
Thus, in keeping with these precepts, the past practice of this Court 'and others has been to entertain jurisdictional challenges even when not advanced until a petition for rehearing is filed.

. AEDPA § 440(a) amends INA § 106(a), 8 U.S.C. § 1105a(a), which formerly designated the Courts of Appeals as the exclusive fora for "judicial review of all final orders of deportation" except to the extent that limited additional judicial review was available via habeas corpus proceedings, see INA § 106(a)(10). AEDPA § 440(a) supplants existing paragraph (10) of Subsection (a) of INA § 106(a) with the following language:
Any final order of deportation against an alien who is deportable by reason of having committed a criminal offense covered in section 1251(a)(2)(A)(iii), (B), (C), or (D) of this title, or any offense covered by section 1251(a)(2)(A)(ii) of this title for which both predicate offenses are covered by section 1251(a)(2)(A)(I) of this title, shall not be subject to review by any court.
AEDPA § 440(a). The pre-AEDPA INA § 106(a)(10) was repealed by AEDPA § 401(e).
. The question of whether AEDPA § 440(a) applies retroactively has already been settled in this Circuit. In
