Gustavo Enrique Alvear-Velez, a native and citizen of Colombia, was admitted lawfully into the United States in 1990. In 1999, the Immigration and Naturalization Service (“INS”), now the Department of Homeland Security (“DHS”), commenced removal proceedings against Mr. AlvearVelez on the ground that he had been convicted of an aggravated felony. See 8 U.S.C. § 1227(a)(2)(A)(iii); id. § 1101(a)(43)(A). The immigration judge (“IJ”) terminated the proceedings based on Mr. Alvear-Velez’s res judicata defense, but, on appeal, the Board of Immigration Appeals (“BIA” or “Board”) determined that the IJ had erred in applying res judicata. The Board then remanded the case to the IJ.
On remand, Mr. Alvear-Velez applied for a waiver of deportability under *675 former-section 212(c) of the Immigration and Nationality Act (“INA”), 8 U.S.C. § 1182(c) (repealed 1996). The IJ determined that Mr. Alvear-Velez was removable based on a 1993 sexual assault conviction and also determined that he was statutorily ineligible for a section 212(c) waiver based on In re Blake, 23 I. & N. Dec. 722 (BIA 2005). Mr. Alvear-Velez appealed the IJ’s decision, but the BIA dismissed the appeal. Mr. Alvear-Velez timely petitioned for review of the BIA’s decision. 1
For the reasons set forth in this opinion, we deny Mr. Alvear-Velez’s petition for review.
I
BACKGROUND
Mr. Alvear-Velez is a native and citizen of Colombia. He entered the United States as a lawful permanent resident on October 6, 1990, at the age of 15. Mr. Alvear-Velez’s entire immediate family resides in the United, States. On April 30, 1993, he pleaded guilty to criminal sexual assault by a family member, in violation of Illinois law. He was sentenced to “periodic imprisonment” for twelve months and supervised probation for forty-eight months, and he served eight months of his imprisonment in a work-release program. A.R. at 247.
In 1994, the immigration authorities commenced deportation proceedings against Mr. Alvear-Velez based on his criminal sexual assault conviction, charging him with having been convicted of a crime involving moral turpitude within five years of. entry, for which he was sentenced to imprisonment or actually confined for one year or more. See 8 U.S.C. § 1251 (a)(2)(A)(i) (renumbered in . 1996). Mr. Alvear-Velez moved to terminate the proceedings. He argued that his crime was not one of moral turpitude and that he had not been sentenced to confinement or actually confined for one year or more.
During the course of those deportation proceedings, the IJ determined that the crime was one of moral turpitude, but that Mr. Alvear-Velez had not been sentenced to imprisonment or confined for more than a year. Consequently, the IJ terminated the deportation proceedings. The INS filed an appeal, which it subsequently withdrew. Accordingly, the IJ’s order of June 14, 1994, dismissing the deportation proceedings became a final administrative order. See 8 C.F.R. § 1003.39.
On June 14, 1999, Mr. Alvear-Velez reported to the police station to register as a sexual offender, as he was required to do every year. The police determined that he had missed a prior reporting date because he had moved in the interim and therefore arrested him. On June 18, 1999, the DHS served him with a notice to appear in removal proceedings to answer the charge that, under 8 U.S.C. § 1227(a)(2)(A)(iii), he was subject to removal as an alien convicted of an aggravated felony as defined by 8 U.S.C. § 1101(a)(43)(A). The predicate *676 felony was Mr. Alvear-Velez’s 1993 conviction, the same conviction that had served as the basis for his 1994 deportation proceedings.
Mr. Alvear-Velez, through counsel, contended that res judicata barred the DHS from initiating proceedings a second time using the same conviction. The IJ agreed. The DHS appealed, and the BIA sustained the appeal, vacated the IJ’s decision and remanded the case for further proceedings. The Board explained that, although both immigration proceedings were based on the same 1993 conviction, “the law governing immigration consequences of criminal convictions ha[d] changed significantly” since the prior proceedings. A.R. at 248. The Board noted that the definition of aggravated felony had been expanded to include sexual abuse of a minor. “In view of this change in law,” the Board continued, “we find that the doctrine of res judicata does not preclude the Service from relying on the 1993 conviction to pursue the respondent’s deportation.” Id.
On remand to the IJ, Mr. Alvear-Velez indicated an intention to seek waiver of his removal under INA § 212(c), 8 U.S.C. § 1182(c) (repealed 1996). 2 The proceedings were continued twice, and, in the interim, the BIA issued its ruling in In re Blake, 23 I. & N. Dec. 722 (BIA 2005). In that decision, the BIA held that an alien deportable because of a conviction for sexual abuse of a minor is not eligible for a section 212(c) waiver because there is no statutory counterpart of that ground of deportability in the enumerated grounds of inadmissibility in section 212(a) of the INA. When Mr. Alvear-Velez’s removal proceedings recommenced, the IJ held that, based on Blake, Mr. Alvear-Velez was ineligible for a section 212(c) waiver.
Mr. Alvear-Velez timely appealed to the BIA. The BIA determined that Mr. Alvear-Velez’s 1993 Illinois conviction qualifies as an aggravated felony for sexual abuse of a minor, which rendered him ineligible for a section 212(c) waiver. The Board accordingly dismissed the appeal.
Mr. Alvear-Velez timely petitioned for review of the BIA’s decision.
II
DISCUSSION
Mr. Alvear-Velez challenges the BIA’s decision on several grounds. First, he contends that the doctrine of res judicata bars the immigration authorities from instituting removal proceedings based on the same criminal conviction that had formed the basis of their prior, unsuccessful deportation effort. Second, he submits that the removal proceedings instituted in this case violate the transitional rules governing the implementation of the Illegal Immigration Reform and Immigrant Responsibility Act of 1996 (“IIRIRA”), Pub.L. No. 104-208, § 309, 110 Stat. 3009, 3009-625-27. Third, Mr. Alvear-Velez claims that the instant removal proceedings violate established immigration procedures because the DHS could have filed a motion to reopen his original deportation proceedings rather than commencing removal proceedings in 1999. Fourth, Mr. AlvearVelez contends that the DHS violated his substantive due process rights by instituting these proceedings. 3
*677 A.
We first turn to Mr. Alvear-Velez’s contention that the Board committed legal error in determining that the doctrine of res judicata did not prevent the DHS from charging him as being removable based on the same criminal conviction for which he previously was found not to be deportable.
The applicability of res judicata hinges on three elements: “(1) an identity of the parties or their privies; (2) identity of the cause of action; and (3) a final judgment on the merits.”
Prochotsky v. Baker & McKenzie,
As a general matter, res judicata applies to administrative hearings if “the administrative agency is acting in a judicial capacity and resolves disputed issues of fact properly before it where the parties have had an adequate opportunity to litigate.”
United States v. Utah Constr. & Mining Co.,
In
United States v. Fisher,
The Superfund amendments under which the present suit was filed were enacted four years after the consent decree was signed. The amendments direct the EPA in no uncertain terms to take peremptory steps to protect the public health. The EPA has no authority to refuse to enforce the statute just because its staff made commitments before Congress spoke.
Id.
As
Fisher
suggests, in determining whether the doctrine of res judicata should be applied with less rigidity than usual, courts have placed great weight on the identity of the institution of government responsible for the change in law. Notably, although changes in case law almost never provide a justification for instituting a new action arising from the same dispute that already has been litigated to a final judgment, statutory changes that occur after the previous litigation has concluded may justify a new action.
Federated Dep’t Stores, Inc. v. Moitie,
Additionally, the rule against claim splitting, which is one component of res judicata, is inapplicable when a statutory change creates a course of action unavailable in the previous action.
Cf. Car Carriers, Inc. v. Ford Motor Co.,
*679
In the present case, when the immigration authorities first sought to deport Mr. Alvear-Velez based on his 1993 Illinois conviction for sexual assault, they had to rely on the ground that he had been convicted of a crime involving moral turpitude within five years of entry, A.R. at 247 (noting that Mr. Alvear-Velez was charged as deportable under 8 U.S.C. § 1251(a)(2)(A)(i)); at the time that this earlier deportation proceeding was instituted, Mr. Alvear-Velez’s conviction for sexual assault did not qualify as an aggravated felony,
see
8 U.S.C. § 1101(a)(43) (1995). In 1996, however, Congress amended the statutory definition of aggravated felony, another ground for removal, to include sexual abuse of a minor, and it specifically applied that new definition retroactively “regardless” of how long ago the “conviction was entered.” IIRIRA, §§ 321(a)(1)
&
(b),
RA, therefore, Mr. Alvear-Velez’s 1993 Illinois conviction for sexual assault did qualify as an aggravated felony. Consequently, Congress provided the immigration authorities with a new ground upon which to institute removal proceedings — a ground that had not been available when the immigration authorities had first sought to deport Mr. Alvear-Velez.
Under these circumstances, the two immigration proceedings cannot be said to share an “identity of the cause of action,” a required element of res judicata.
See Prochotsky,
Moreover, two circumstances require a less rigid application of res judicata in this case. The relevant change in the law here is statutory in nature, as opposed to a change in case law, and that change is being applied in the administrative context.
See Fisher,
Finally, we note that the application of res judicata under these circumstances would be inconsistent with IIRIRA’s statutory scheme and therefore would frustrate Congress’ policy decision that aliens convicted of sexual abuse of a minor merit removal regardless of when their convictions occurred.
See
8 U.S.C. § 1101(a)(43). Several of our sister circuits have suggested a similar approach. In
Tran v. Gonzales,
the Sixth Circuit concluded that the immigration authorities could institute new removal proceedings based on “convictions that were previously the subject of closed deportation proceedings.”
Similarly, in
Lopez-Bazante v. Gonzales,
*681 the government could not have taken advantage of [IIRIRA’s] expanded definition of aggravated felonies, which included sexual abuse of a minor, to deport Petitioner. The government’s inaction in challenging the IJ’s 1995 termination of deportation proceedings based on Petitioner’s alleged crimes involving moral turpitude may have resulted in a final judgment with respect to the 1994 second degree rape and sodomy convictions as crimes involving moral turpitude. Under IIRIRA, however, the situation was altered where the expanded class of crimes that qualify as aggravated felonies swept Petitioner’s 1994 convictions in the new grounds for removal. Therefore, the import of the 1994 convictions, as a factual basis for removability, can be relitigated.
Id. (internal quotation marks and citations omitted) (footnote omitted).
The First Circuit also has suggested a similar result under these circumstances. In
Dalombo Fontes v. Gonzales,
the BIA similarly refused to apply res judicata “because the statutory definition of aggravated felony extant at the time of Fontes’s prior removal proceedings was different and far narrower.”
We think that the BIA correctly refused to terminate Fontes’s removal proceedings in light of the clear congressional intent that its broadened definition of aggravated felony be applied retroactively. The government still had to prove that Fontes’s conviction met the new definition of aggravated felony. It was neither an error of law nor an abuse of discretion for the BIA, to whom some deference on interpretation of immigration statutes is owed, not to accept Fontes’s claim that res judicata barred any further proceedings by the government.
Id.
Thus, we must conclude that res judicata does not bar the present removal effort by the DHS. We emphasize that our holding is limited to the peculiar circumstances before us — the res judicata effect of an administrative final judgment rendered prior to a congressional decision to expand the avenues of relief available and to make those additional avenues of relief retroactive.
B.
Mr. Alvear-Velez next contends that the immigration authorities violated IIRIRA’s transitional rules by charging him as being removable based on the same criminal conviction for which he previously was found to be not deportable. Under IIRIRA § 309(c)(1), contends Mr. Alvear-Velez, an alien who was in exclusion or deportation proceedings as of IIRIRA’s effective date was not subject to IIRIRA’s amendments, and the proceedings were to be conducted without regard to those amendments. He notes that, at the time of IIRIRA’s effective date, his deportation proceedings had been terminated for more than two years. According to Mr. Alvear-Velez, Congress’ stated intention not to subject IIRIRA’s amendments to individuals pending in deportation proceedings during the transitional phase must be read as a concomitant intention not to apply IIRIRA’s amendments to individuals whose deportation proceedings already were final.
We cannot accept Mr. Alvear-Velez’s contention. We begin by setting forth the IIRIRA provisions on which Mr. AlvearVelez’s argument relies:
*682 (a) IN GENERAL. — Except as provided in this section and sections 303(b)(2), 306(c), 308(d)(2)(D), or 308(d)(5) of this division, this subtitle and the amendments made by this subtitle shall take effect on the first day of the first month beginning more than 180 days after the date of the enactment of this Act (in this title referred to as the “title III-A effective date”).
(b) PROMULGATION OF REGULATIONS. — The Attorney General shall first promulgate regulations to carry out this subtitle by not later than 30 days before the title III-A effective date.
(c) TRANSITION FOR ALIENS IN PROCEEDINGS.—
(1) GENERAL RULE THAT NEW RULES DO NOT APPLY. — Subject to the succeeding provisions of this subsection, in the case of an alien who is in exclusion or deportation proceedings as of the title III-A effective date—
(A) the amendments made by this subtitle shall not apply, and
(B) the proceedings (including judicial review thereoD shall continue to be conducted without regard to such amendments.
IIRIRA §§ 309(a)-(c). As evident from the statutory language, the transitional rules on which Mr. Alvear-Velez relies, by their own terms, apply only to “the amendments made by this subtitle.”
Id.
§ 309(c)(1)(A);
see also id.
§ 309(a). That subtitle is subtitle A, which revised the procedures for the removal of aliens.
See Tran,
The amended and retroactive definition of aggravated felony,
see
IIRIRA §§ 321(a)-(b), by contrast, is set forth in subtitle B, entitled “Criminal Alien Provisions,” and contains its own effective date,
see
IIRIRA § 321(c). Section 321(c) states: “The amendments made by this section shall apply to actions taken on or after the date of enactment of this Act [September 30, 1996], regardless of when the conviction occurred....”
See also Tran,
There is no dispute in this case that the removal charges against Mr. Alvear-Velez constitute, under IIRIRA § 321(c), an “action taken” on or after the date of enactment of IIRIRA, September 30,1996. These proceedings were instituted in 1999, and, therefore, the amended and retroactive definition of aggravated felony was applied properly to his 1993 Illinois conviction.
See, e.g., Tran,
*683 Conclusion
For the foregoing reasons, the petition for review is denied.
Petition for Review Denied.
Notes
. Under 8 U.S.C. § 1252(a)(1), we have jurisdiction to review final orders of removal issued by the Board. In cases where an alien has been found removable on the ground that he committed an aggravated felony offense, as is the case here, our jurisdiction is limited to reviewing "constitutional claims” and "questions of law.”
See
8 U.S.C. §§ 1252(a)(2)(C), (D). All of Mr. Alvear-Velez's arguments satisfy this requirement. The application of res judicata is a question of law, and therefore we have jurisdiction to review Mr. Alvear-Velez’s challenge on that ground.
See Hamdan v. Gonzales,
.
See also INS v. St. Cyr,
. In his main brief, Mr. Alvear-Velez also challenged the Board's determination that,
*677
under
In re Blake,
23 I. & N. Dec. 722 (BIA 2005), his 1993 conviction for criminal sexual assault cannot be waived under section 212(c) of the INA. At oral argument, however, Mr. Alvear-Velez conceded that this argument was foreclosed by our decisions in
Valere v. Gonzales,
.
See also Computer Assoc. Int’l, Inc. v. Altai, Inc.,
It is worth noting, however, that the “argument that it was not possible to bring all related theories of recovery or demands for relief in a first action may not overcome a claim-preclusion defense
if
the plaintiff could have made it possible.” 18 Wright, Miller & Cooper,
supra,
§ 4409, at 246 (emphasis added);
see also Supporters to Oppose Pollution, Inc. v. Heritage Group,
. Ninth Cir. R. 36 — 3(b) ("Unpublished dispositions and orders of this Court issued on or after January 1, 2007 may be cited to the courts of this circuit in accordance with Fed. R.App. P. 32.1.”). Lopez-Bazante was decided on April 20, 2007.
. As we noted earlier, Mr. Alvear-Velez makes two other arguments. Neither requires extended discussion. Mr. Alvear-Velez contends that the immigration authorities, rather than filing new removal proceedings in 1999, could have filed on or before September 30, 1996, a motion to reopen his original deportation proceedings, under 8 C.F.R. § 1003.23(b)(1). Because the immigration authorities did not do so, he submits, the new proceedings should have been terminated. Although Mr. Alvear-Velez is correct that this option was available to the immigration authorities, nothing in regulation section
*683
1003.23(b)(1) suggests that this was the immigration authorities’ only manner of proceeding. Cf.
Charmer,
Mr. Alvear-Velez's final contention is that the present removal proceedings violate his substantive due process rights under the Fifth Amendment. He contends that “[s]ubstantive due process offers protection against repeated litigation of the same issue by an administrative agency.” Petitioner's Br. at 22.
Mr. Alvear-Velez has not presented a valid substantive due process challenge to the DHS’ decision to institute removal proceedings based on the same criminal conviction for which he previously was found not to be deportable. In challenging the decision of the DHS to institute these proceedings, Mr. Alvear-Velez is challenging executive action. Therefore, to succeed in his substantive due process claim, he must show that the executive action is so egregious that it "shocks the conscience.”
