OPINION
Marco Antonio Robles-Urrea, a lawful permanent resident of the United States, petitions for review of a precedential decision of the Board of Immigration Appeals (“BIA”), holding that his conviction for misprision of a felony is categorically a crime involving moral turpitude under 8 U.S.C. § 1182(a)(2)(A)(i)(I). We have jurisdiction under 8 U.S.C. § 1252(a)(2)(D) to review constitutional and legal questions raised by aliens found removable on the basis of criminal activity.
Galeana-Mendoza v. Gonzales,
A crime involving moral turpitude is either one that involves fraud or one that involves grave acts of baseness or depravity, such that its commission “offend[s] the most fundamental values of society.”
Navarro-Lopez v. Gonzales,
We remand, however, to allow the BIA to conduct a modified categorical analysis of Robles-Urrea’s conviction,
see INS v. Ventura,
I
In 2002, Robles-Urrea pleaded guilty to misprision of a felony under 18 U.S.C. § 4, which states that any person who,
having knowledge of the actual commission of a felony cognizable by a court of the United States, conceals and does not as soon as possible make known the same to some judge or other person in civil or military authority under the United States, shall be fined under this title or imprisoned not more than three years, or both.
The felony that Robles-Urrea allegedly concealed was conspiracy to distribute marijuana and cocaine.
In 2005, having served his sentence for misprision, Robles-Urrea was stopped at the Arizona border as he was returning to the United States from Mexico. 1 The Department of Homeland Security (“DHS”) served him with a Notice to Appear, charging him with removability under 8 U.S.C. § 1182(a)(2)(C) as a drug trafficker. DHS subsequently charged him with an additional ground of removability under 8 U.S.C. § 1182(a)(2)(A)(i)(I), for having been convicted of a crime involving moral turpitude.
Robles-Urrea contested both charges and applied for cancellation of removal. The Immigration Judge (“IJ”) found him removable but did not specify on which ground. 2 The IJ also found him ineligible for cancellation of removal under 8 U.S.C. § 1229b because his conviction for misprision of a felony had prevented him from accruing the requisite five years of permanent residency and seven years of lawful residency in the United States.
Robles-Urrea appealed, arguing that he is not inadmissible under either § 1182(a)(2)(A)(i)(I) or § 1182(a)(2)(C) and that he is eligible for cancellation of removal. On April 10, 2006, the BIA dismissed the appeal, finding “that one who knows a felony has been committed and takes affirmative steps to conceal the crime or to prevent its discovery by the authorities has committed a crime involving moral turpitude.” The BIA also held that Robles-Urrea’s commission of this offense, which could not fall under the petty offense exception, interrupted the requisite seven-year residency under the “stop-time rule,” 8 U.S.C. § 1229b(d)(l). It did not decide whether Robles-Urrea was removable for drug trafficking under 8 U.S.C. § 1182(a)(2)(C). Robles-Urrea filed a timely petition for review, docketed as No. 06-71935, from this order.
Robles-Urrea also filed with the BIA a motion to reconsider, arguing that the BIA’s decision conflicted with Matter of Sloan, 12 I. & N. Dec. 840 (A.G.1968, BIA 1966), which had held that misprision of a felony is not a crime involving moral turpitude and that the stop-time rule does not apply retroactively. The BIA granted the motion to reconsider and issued a prece *707 dential decision on September 27, 2006, overruling Matter of Sloan and holding that misprision of a felony is a crime involving moral turpitude. Matter of Robles-Urrea, 24 I. & N. Dec. 22 (BIA 2006). The BIA also concluded that the stop-time rule could apply retroactively. Id. The BIA thus reaffirmed its dismissal of Robles-Urrea’s appeal. Robles-Urrea filed a timely petition for review, docketed as No. 06-74826, from this second BIA decision. That petition has been consolidated with his original petition for review.
We have jurisdiction to decide the question of law that Robles-Urrea raises: whether misprision of a felony qualifies as a crime involving moral turpitude.
See
8 U.S.C. § 1252(a)(2)(D);
Galeana-Mendoza,
II
We begin by reviewing the BIA’s determination that misprision of a felony is categorically a crime involving moral turpitude. To determine whether a given offense constitutes a crime involving moral turpitude, we apply the categorical and modified categorical approaches set forth in
Taylor v. United States,
When the elements of a given offense of conviction are clear, as they are here, “our review of the BIA’s determination that such offense constitutes a ‘crime of moral turpitude’ is governed by the same traditional principles of administrative deference we apply to the Board’s interpretation of other ambiguous terms in the INA.”
Marmolejo-Campos,
Because Congress has not spoken directly to the question at issue, we consider whether the BIA has permissibly interpreted the statute. We conclude that the BIA’s interpretation of the INA is impermissible. Instead, we hold that misprision of a felony is not categorically a crime involving moral turpitude.
*708 A
Although the INA does not define “crime involving moral turpitude,” courts and the BIA have generally defined this term as comprising crimes that are “inherently base, vile, or depraved, and contrary to the accepted rules of morality and the duties owed between persons or to society in general.”
Robles-Urrea,
24 I. & N Dec. at 25;
see also Navarro-Lopez,
As this definition makes clear, and as we explained in
Navarro-Lopez,
not all offenses against the accepted rules of social conduct qualify as crimes involving moral turpitude. For that matter, not all offenses against the accepted rules of social conduct qualify as crimes at all. “[0]ffenses that are so base, vile, and depraved that they qualify as crimes of moral turpitude ‘even though they have no element of fraud’” typically “involve ‘rather grave acts of baseness or depravity’ such as murder, rape, and incest.”
Id.
(quoting
Rodriguez-Herrera v. INS,
Not all serious crimes meet this standard .... Indeed, we have determined, for example, that burglary, Cuevas-Gaspar v. Gonzales,430 F.3d 1013 , 1020 (9th Cir.2005), and assault with a deadly weapon, Carr v. INS,86 F.3d 949 , 951 (9th Cir.1996), do not involve moral turpitude. To be considered a crime of moral turpitude, a crime other than fraud must be more than serious; it must offend the most fundamental moral values of society, or as some would say, ‘shock[ ] the public conscience.’ Medina v. United States,259 F.3d 220 , 227 (4th Cir.2001) (quoting Matter of Danesh, 19 I. & N. Dec. 669, 670 (BIA 1988)).
Id. at 1074-75 (alteration in original). Only truly unconscionable conduct surpasses the threshold of moral turpitude. 3 We must determine whether misprision of a felony is categorically so base, vile, or depraved as to be morally turpitudinous.
B
We begin that inquiry by reviewing the BIA’s reasoning. Although the BIA properly recites the definition of a crime involving moral turpitude — noting that such a crime must be “inherently base, vile, or depraved” as well as “contrary to the accepted rules of morality and the duties owed between persons or to society in general,” 24 I. & N Dec. at 25 — it entirely fails to explain why misprision of a felony is “inherently base, vile, or depraved.” The BIA relies almost wholly on a rationale introduced by the Eleventh Circuit in
Itani v. Ashcroft,
The problem with this reasoning is that it “omit[s] the second crucial element of the definition of a crime involving moral turpitude: that the crime involve some level of depravity or baseness ‘so far contrary to the moral law’ that it gives rise to moral outrage.”
Navarro-Lopez,
commission of any crime, by definition, runs contrary to some duty owed to society. If this were the sole benchmark for a crime involving moral turpitude, every crime would involve moral turpitude. We certainly owe a duty to society not to destroy another’s property, not to assault another, and not to break and enter private property. Yet, we have held that convictions for these acts do not categorically involve moral turpitude.
Id. at 1070-71; see also id. at 1077 (Reinhardt, J., concurring for the majority).
The Itani rationale is contrary to the statutory scheme: “[i]f Congress had intended any conviction to make an alien ineligible for cancellation of removal,” then it would not have “designate[d] specific categories of crimes” to have this effect. Id. at 1071 (majority opinion).
Having recapitulated the flawed reasoning of
Itani
and of the no longer precedential panel decision in
Navarro-Lopez,
the BIA’s opinion pronounces in a conclusory fashion that misprision of a felony “is inherently base or vile.” 24 I. & N. Dec. at 26. This
ipse dixit
lacks any reasoned foundation. So does the BIA’s argument that misprision of a felony must be morally turpitudinous because “evil intent” is “implicit in the statutory requirement that the actor .take an affirmative step
to conceal
a felony from the proper authorities.”

N. Dec. at 27 (citing

Our
de novo
review of the issue lends no more support to the result that the BIA reaches. The government argues that misprision of a felony is base, vile, and depraved because it has been historically condemned. Gov’t Br. 32-33. There is no question that “gross indifference to the duty to report known criminal behavior remains a badge of irresponsible citizenship.”
Roberts v. United States,
Misprision of a felony differs from other crimes of concealment that have been found to involve moral turpitude, because it requires not a specific
intent
to conceal or obstruct justice, but only
knowledge
of the felony.
Cf. Padilla v. Gonzales,
The BIA’s holding would result in a peculiar rule: even where a principal of
*711
fender has not committed a crime involving moral turpitude, a person who conceals that crime — and who thereby commits misprision of a felony — might be considered to have done so. In
Navarro-Lopez,
we pointed out the “absurd result” that if any “conviction for accessory-after-the-fact is necessarily a crime of moral turpitude,” then even when “a principal who commits a crime may not have undertaken a morally turpitudinous act, ... the person who gave the principal food and shelter” may be deemed necessarily to have done so.
We therefore find a “a realistic probability, not [just] a theoretical possibility,”
Gonzales,
Ill
Because the offense of misprision of a felony “is categorically broader than the generic definition of a crime” involving moral turpitude, we must proceed to the modified categorical approach, examining whether the particular circumstances of Robles-Urrea’s conviction rendered it morally turpitudinous.
Navarro-Lopez,
Robles-Urrea argues that even under
Aguilar-Montes de Oca,
the modified categorical approach is inappropriate here, because “under no realistic prosecutorial theory would the non-element of depravity have been unnecessary to obtain a conviction for misprision of a felony.” Supp. Br. at 5. Robles-Urrea misunderstands the rationale of
Aguilar-Montes de Oca.
That opinion explained by way of example why it is appropriate to apply the modified categorical approach to determine whether a defendant has been convicted of an assault using a gun, even where the use of a gun is not an element of the defendant’s crime of conviction. If the judicially noticeable “documents establish that the fact-finder necessarily found that the defendant satisfied the ‘harmful contact’ element [of a hypothetical statute] by inflicting harmful contact with a gun,” the majority wrote, “then the conviction ‘necessarily rested’ on this fact.”
The only question that remains is whether we must remand for the agency to conduct the modified categorical analysis. We have severe doubts as to the merits of each of the government’s arguments as to why the agency could conclude that, even if misprision of a felony is not categorically a crime involving moral turpitude, RoblesUrrea’s conviction was for a morally turpitudinous crime. Nonetheless, we recognize that the BIA is entitled to conduct the analysis in the first instance.
See Ventura,
IV
Because the BIA impermissibly interpreted the INA in holding that misprision *713 of a felony is categorically a crime involving moral turpitude, we grant Robles-Urrea’s second petition for review, we deny the first as moot, and we remand for the agency to apply the modified categorical approach. On remand, the BIA may also consider whether Robles-Urrea is removable under 8 U.S.C. § 1182(a)(2)(C)(i), as an alien who “has been an illicit trafficker in any controlled substance,” and whether he may be entitled to any form of relief from removal. If it concludes that he is removable under § 1182(a)(2)(C)(i) and not entitled to relief, it need not reach the question whether his conviction was for a crime involving moral turpitude.
No. 06-71935: DISMISSED AS MOOT.
No. 06-74826: GRANTED and REMANDED.
Notes
. Robles-Urrea was stopped under 8 U.S.C. § 1101(a)(13), as a returning resident alien applying for admission with a prior criminal conviction.
. From the transcript of the hearing, it seems that the IJ sustained the charge of inadmissibility based on the conviction for misprision of a felony, which would be the moral turpitude ground. The IJ may have been confused about the nature of the conviction, however, as his order refers to the offense as "administration of a felony.”
. In
Matter of Silva-Trevino,
24 I. & N. Dec. 687 (BIA 2008), the Attorney General purported to "establish a uniform framework for ensuring that the Act's moral turpitude provisions are fairly and accurately applied.”
Id.
at 688. "[W]e have been hesitant to defer to such general statements,” however, because the agency’s "general understanding of the term 'moral turpitude’ is not the result of 'any insights that it might have obtained from adjudicating immigration cases,’ but simply a recitation of the definition found in the criminal law.”
Marmolejo-Campos,
. Our order granting rehearing en banc in Navairo-Lopez (and rendering the panel opinion non-precedential) was not available to the BIA and was not filed until November 8, 2006, over a month after the BIA rendered its opinion in this matter.
. The quotation comes from Justice Jackson's dissent in
Jordan v. DeGeorge,
.In rejecting the BIA's reasoning, we do not rely on the fact that the BIA changed course, reversing its earlier decision in
Matter of Sloan.
"Un-explained inconsistency is ... a reason for holding an interpretation to be arbitrary and capricious change from agency practice under the Administrative Procedure Act.”
Nat’l Cable & Telecomms. Ass’n v. Brand X Internet Servs.,
. In a later case, Matter of Tejwani, 24 I. & N. Dec. 97 (BIA 2007), the BIA explained that such a result is permissible because the affirmative concealment of a crime involves fraudulent behavior, regardless of the underlying crime. Id. at 99. The BIA's opinion here, however, does not offer this rationale or rely on a finding of fraudulent behavior.
. The BIA did not consider whether misprision of a felony is a crime involving moral turpitude because it is an "offense involving fraud,” except to the extent that it relied on the Eleventh Circuit's decision in
Itani,
which had employed a fraud-based analysis. We need not decide whether misprision of a felony is an offense involving fraud, because "this court cannot affirm the BIA on a ground upon which it did not rely.”
Navas v. INS,
If we were required to reach the issue, however, we would conclude that misprision of a felony does not involve fraud. "A crime involves fraudulent conduct, and thus is a crime involving moral turpitude, if intent to defraud is explicit in the statutory definition of the crime or implicit in the nature of the crime.”
Blanco v. Mukasey,
. We disagree with Robles-Urrea’s argument that
Aguila-Montes de Oca
should not apply retroactively to his case. Robles-Urrea entered his guilty plea in 2002, and his conviction became final in 2003. He therefore cannot have relied on our 2007 decision in
Navatro-Lopez,
which
Aguila-Montes de Oca
overruled.
