    SUMMARY**
    Immigration
    The panel granted Augustin Valenzuela Gallardo’s
    petition for review of the Board of Immigration Appeals’
    precedential published opinion in Matter of Valenzuela
    Gallardo, 
    25 I. & N. Dec. 838
     (BIA 2012), holding that a
    conviction for accessory to a felony under California Penal
    Code § 32 is an aggravated felony “offense relating to
    obstruction of justice” under Immigration and Nationality Act
    § 101(a)(43)(S).
    The panel wrote that the BIA’s revised interpretation of
    obstruction of justice to require only “the affirmative and
    intentional attempt, with specific intent, to interfere with the
    process of justice,” departed from its prior construction of the
    statute by requiring no nexus to an ongoing investigation or
    proceeding. The panel held that the new construction raises
    grave doubts about whether § 101(a)(43)(S), so construed, is
    unconstitutionally vague. The panel remanded for the BIA to
    apply its previous interpretation in In re Espinoza-Gonzalez,
    
    22 I. & N. Dec. 889
     (BIA 1999) (en banc), or to offer a new
    construction.
    Dissenting, Judge Seabright wrote that the majority
    mistakenly found that the BIA in In re Espinoza-Gonzalez
    had previously required a nexus to an ongoing investigation
    or proceeding, and that the BIA’s opinion in Matter of
    Valenzuela Gallardo did not announce a new interpretation

    removing the requirement. Judge Seabright wrote that rather
    Matter of Valenzuela Gallardo explicitly clarified language
    in In re Espinoza-Gonzalez in light of what the BIA
    considered to be this court’s misreading of BIA precedent in
    Hoang v. Holder, 
    641 F.3d 1157
     (9th Cir. 2011). Judge
    Seabright would also find that the absence of a requirement
    for an ongoing investigation or proceeding does not render
    the BIA’s definition vague, much less create grave
    constitutional doubts.

    OPINION
    CHRISTEN, Circuit Judge:
    Augustin Valenzuela Gallardo, a citizen of Mexico,
    pleaded guilty to violating California Penal Code § 32,
    accessory to a felony. An immigration judge (IJ) ordered him
    removed to Mexico, concluding that his conviction
    constituted an “offense relating to obstruction of justice” and
    therefore an aggravated felony under the Immigration and
    Nationality Act (INA) § 101(a)(43)(S). The Board of
    Immigration Appeals (BIA) dismissed Valenzuela Gallardo’s
    4           VALENZUELA GALLARDO V. LYNCH
    appeal. In its decision, it announced a new interpretation of
    “obstruction of justice” that requires only “the affirmative
    and intentional attempt, with specific intent, to interfere with
    the process of justice.” Contrary to the prior construction,
    this interpretation of INA § 101(a)(43)(S) requires no nexus
    to an ongoing investigation or proceeding. Valenzuela
    Gallardo petitions for review, arguing that the agency’s
    revised interpretation of the statute raises serious
    constitutional concerns about whether the statute is
    unconstitutionally vague. We agree and remand to the Board
    for application of the previous interpretation or formulation
    of a construction that does not raise grave constitutional
    doubts.
    BACKGROUND
    I. Facts
    Augustin Valenzuela Gallardo was admitted to the United
    States as a lawful permanent resident in 2002. In November
    2007, police discovered him in a stolen vehicle with
    possession of methamphetamine, ecstacy, and a loaded
    firearm. Valenzuela Gallardo was arrested and charged with
    two counts of possession of a controlled substance
    (methamphetamine) in violation of California Health and
    Safety Code § 11378, one count of possessing
    methamphetamine while armed in violation of California
    Health and Safety Code § 11370.1, and one count of failing
    to comply with the terms of his probation in violation of
    California Penal Code § 1203. He agreed to plead guilty to
    an amended count of accessory to a felony in violation of
    California Penal Code § 32. All remaining charges were
    dismissed. Initially, Valenzuela Gallardo was placed on
    probation, but he subsequently violated the terms of his
    VALENZUELA GALLARDO V. LYNCH                     5
    probation and was sentenced            to   sixteen   months’
    imprisonment.
    II. Proceedings
    In June 2010, the Government placed Valenzuela
    Gallardo in removal proceedings. The Government argued
    that a conviction under California Penal Code § 32 constitutes
    an “offense relating to obstruction of justice,” and therefore
    an aggravated felony under INA § 101(a)(43)(S).
    Valenzuela Gallardo filed a motion to terminate removal
    proceedings in July 2010.          He appeared before an
    immigration judge and contested removability on the grounds
    that his conviction was not an offense “relating to obstruction
    of justice” because “the federal ‘Obstruction of Justice’
    grounds must relate to an extant judicial proceeding.”
    The IJ denied Valenzuela Gallardo’s motion to terminate
    removal proceedings. The IJ reasoned that the BIA had
    previously held that the federal crime of accessory after the
    fact, 
    18 U.S.C. § 3
    , is an aggravated felony, that there was
    “no material difference” between § 3 and California Penal
    Code § 32, and that the BIA has not “limit[ed] the scope of
    the obstruction of justice aggravated felony to cases in which
    there is a pending judicial proceeding.” The IJ thus
    concluded that a conviction under California Penal Code § 32
    is an “offense relating to obstruction of justice,” and ordered
    Valenzuela Gallardo removed to Mexico.
    Valenzuela Gallardo filed an appeal but the BIA
    dismissed it. After the BIA denied Valenzuela Gallardo’s
    motion to reconsider, he petitioned for review and requested
    6            VALENZUELA GALLARDO V. LYNCH
    a stay of removal. Our court dismissed that petition for lack
    of jurisdiction.
    In May 2011, we issued an opinion in Trung Thanh
    Hoang v. Holder, a case that looked to two prior BIA
    decisions and held, under the agency’s interpretation, that a
    crime constitutes an obstruction of justice crime “when it
    interferes with an ongoing proceeding or investigation.”
    
    641 F.3d 1157
    , 1164 (9th Cir. 2011) (some emphasis added).
    In light of our opinion in Hoang, the BIA sua sponte
    reopened Valenzuela Gallardo’s proceedings for further
    consideration of his removability. In the opinion that
    followed, In re Valenzuela Gallardo, a three-judge panel of
    the BIA sought “to clarify [the BIA’s] prior precedents on the
    scope of the phrase ‘relating to obstruction of justice,’” and
    rejected Hoang’s holding. 
    25 I. & N. Dec. 838
    , 840, 842
    (B.I.A. 2012). The three-judge panel announced that
    “obstruction of justice” requires only:
    the affirmative and intentional attempt, with
    specific intent, to interfere with the process of
    justice—[this] demarcates the category of
    crimes constituting obstruction of justice.
    While many crimes fitting this definition will
    involve interference with an ongoing criminal
    investigation or trial, we now clarify that the
    existence of such proceedings is not an
    essential element of “an offense relating to
    obstruction of justice.”
    
    Id. at 841
     (emphasis added) (citation omitted). In light of this
    interpretation, the BIA concluded that Valenzuela Gallardo’s
    conviction was an offense “relating to obstruction of justice.”
    VALENZUELA GALLARDO V. LYNCH                    7
    
    Id. at 844
    . Because Valenzuela Gallardo was ultimately
    sentenced to more than one year of imprisonment for his
    offense, the BIA concluded that his conviction was for an
    aggravated felony. 
    Id.
     It therefore dismissed Valenzuela
    Gallardo’s reopened appeal. 
    Id.
    Valenzuela Gallardo petitions for review, challenging the
    BIA’s most recent interpretation of INA § 101(a)(43)(S). We
    have jurisdiction under 
    8 U.S.C. § 1252
    (a)(2)(D), and we
    hold that the BIA’s new construction of “obstruction of
    justice” raises grave doubts about whether the statute, so
    construed, is unconstitutionally vague. Because we see no
    clear indication that Congress intended to delegate authority
    to the agency to push the constitutional boundary, we remand
    to the agency, as the agency requested, for consideration of a
    new construction or application of the interpretation it
    previously announced in In re Espinoza-Gonzalez, 
    22 I. & N. Dec. 889
     (B.I.A. 1999) (en banc), and to which we deferred
    in Hoang, 
    641 F.3d at 1161
    .
    STANDARD OF REVIEW
    We review legal questions de novo. Perez-Enriquez v.
    Gonzales, 
    463 F.3d 1007
    , 1009 (9th Cir. 2006). Where, as
    here, the BIA reviews an IJ’s decision de novo, our review is
    limited to the BIA’s decision. Shah v. INS, 
    220 F.3d 1062
    ,
    1067 (9th Cir. 2000).
    8            VALENZUELA GALLARDO V. LYNCH
    DISCUSSION
    I. The BIA’s most recent interpretation departs from its
    prior interpretations.
    “Any alien who is convicted of an aggravated felony at
    any time after admission is deportable.”             
    8 U.S.C. § 1227
    (a)(2)(A)(iii). The INA does not separately define
    “aggravated felony.” Instead, it refers to a list of qualifying
    criminal offenses, which includes offenses “relating to
    obstruction of justice, perjury or subornation of perjury, or
    bribery of a witness, for which the term of imprisonment is at
    least one year.” INA § 101(a)(43)(S).
    In 1997, a twelve-member en banc panel of the BIA ruled
    in In re Batista-Hernandez that the federal crime of accessory
    after the fact, 
    18 U.S.C. § 3
    , “clearly relates to obstruction of
    justice” and constitutes an aggravated felony under INA
    § 101(a)(43)(S). 
    21 I. & N. Dec. 955
    , 961 (B.I.A. 1997). The
    Board explained:
    [T]he wording of 
    18 U.S.C. § 3
     itself indicates
    its relation to obstruction of justice, for the
    statute criminalizes actions knowingly taken
    to “hinder or prevent (another’s)
    apprehension, trial or punishment.” . . . [T]he
    nature of being an accessory after the fact lies
    essentially in obstructing justice and
    preventing the arrest of the offender.
    
    Id.
    Two years later, a sixteen-member en banc panel of the
    BIA issued Espinoza-Gonzalez and concluded that misprision
    VALENZUELA GALLARDO V. LYNCH                   9
    of felony, 
    18 U.S.C. § 4
    , does not constitute obstruction of
    justice and is not an aggravated felony under INA
    § 101(a)(43)(S). 
    22 I. & N. Dec. 889
    , 897 (B.I.A. 1999). The
    BIA reasoned:
    We do not believe that every offense that, by
    its nature, would tend to “obstruct justice” is
    an offense that should properly be classified
    as “obstruction of justice.” The United States
    Code delineates a circumscribed set of
    offenses that constitute “obstruction of
    justice,” and although misprision of felony
    bears some resemblance to these offenses, it
    lacks the critical element of an affirmative and
    intentional attempt, motivated by a specific
    intent, to interfere with the process of
    justice. . . . [W]here the obstruction of justice
    offenses are broadly stated, courts have
    interpreted them narrowly. To include all
    offenses that have a tendency to, or by their
    nature do, obstruct justice would cast the net
    too widely.
    
    Id.
     at 893–94 (citation omitted).        Espinoza-Gonzalez
    distinguished misprision of felony from accessory after the
    fact, which had been at issue in Batista-Hernandez:
    The definition of the federal crime of
    accessory after the fact in 
    18 U.S.C. § 3
    requires an affirmative action knowingly
    undertaken “in order to hinder or prevent
    (another’s) apprehension, trial or
    punishment.” Although misprision of a
    felony has as an element the affirmative
    10          VALENZUELA GALLARDO V. LYNCH
    concealment of the felony, there is, unlike § 3,
    nothing in § 4 that references the specific
    purpose for which the concealment must be
    undertaken.     The specific purpose of
    hindering the process of justice brings the
    federal “accessory after the fact” crime within
    the general ambit of offenses that fall under
    the “obstruction of justice” designation.
    Furthermore, concealment of a crime is
    qualitatively different from an affirmative
    action to hinder or prevent another’s
    apprehension, trial, or punishment. It is a
    lesser offense to conceal a crime where there
    is no investigation or proceeding, or even an
    intent to hinder the process of justice, and
    where the defendant need not be involved in
    the commission of the crime. Further,
    accessory after the fact has been defined as
    obstructing justice. United States v. Barlow,
    [
    470 F.2d 1245
    ,] 1252–53 [(D.C. Cir. 1972)].
    
    Id.
     at 894–95 (emphasis added).
    Although the phrase “obstruction of justice” is not
    statutorily defined, the BIA observed that Title 18, Chapter
    73 of the United States Code lists a number of offenses under
    the heading “Obstruction of Justice” and provides
    “substantial guidance, consistent with judicial
    pronouncements on the subject, as to the contours of the
    ‘obstruction of justice’ category of offenses.” Id. at 893, 894
    n.4; see also 
    18 U.S.C. §§ 1501
    –1521. The Board noted:
    VALENZUELA GALLARDO V. LYNCH                            11
    The intent of the two broadest provisions,
    § 1503 (prohibiting persons from influencing
    or injuring an officer or juror generally) and
    § 1510 (prohibiting obstruction of criminal
    investigations), is to protect individuals
    assisting in a federal investigation or judicial
    proceeding and to prevent a miscarriage of
    justice in any case pending in a federal court.
    Id. at 892 (emphasis added) (citation omitted). The BIA also
    found guidance in the Supreme Court’s decision in United
    States v. Aguilar, which narrowly construed § 1503’s
    “catchall phrase”1 to require action taken with an intent to
    influence judicial or grand jury proceedings. 
    515 U.S. 593
    ,
    598–99 (1995) (holding that “[t]he action taken by the
    accused must be with an intent to influence judicial or grand
    jury proceedings”).
    Our court has deferred to the agency interpretation
    announced in Espinoza-Gonzalez on three occasions. See
    Trung Thanh Hoang v. Holder, 
    641 F.3d 1157
    , 1161 (9th Cir.
    2011); Salazar-Luviano v. Mukasey, 
    551 F.3d 857
    , 860 (9th
    Cir. 2008); Renteria-Morales v. Mukasey, 
    551 F.3d 1076
    ,
    1086–87 (9th Cir. 2008). In the proceedings below, a three-
    judge panel of the BIA revisited its en banc court’s
    interpretation of obstruction of justice and clarified that a
    nexus to an “ongoing criminal investigation or trial . . . is not
    an essential element of ‘an offense related to obstruction of
    1
    The catchall phrase in § 1503 provides that obstruction of justice
    includes a person who “corruptly, or by threats of force, or by any
    threatening letter or communication, influences, obstructs, or impedes, or
    endeavors to influence, obstruct, or impede, the due administration of
    justice.” 
    18 U.S.C. § 1503
    (a).

    justice.’” In re Valenzuela Gallardo, 
    25 I. & N. Dec. 838
    ,
    841 (B.I.A. 2012). Applying this broader definition, the BIA
    dismissed Valenzuela Gallardo’s appeal.2 
    Id. at 844
    .
    II. The constitutional avoidance doctrine applies in the
    Chevron context.
    We apply the Chevron framework where, as here, there is
    “binding agency precedent on-point” in the form of a
    published BIA opinion. See Renteria-Morales, 
    551 F.3d at 1081
     (quoting Kharana v. Gonzales, 
    487 F.3d 1280
    , 1283 n.4
    (9th Cir. 2007)). Under the familiar Chevron framework, we
    first ask “whether Congress has directly spoken to the precise
    question at issue.” Chevron, U.S.A., Inc. v. Nat. Res. Def.
    Council, Inc., 
    467 U.S. 837
    , 842 (1984). If the statute
    “unambiguously bars” the agency’s interpretation, that is the
    end of the analysis, see Whitman v. Am. Trucking Ass’ns, Inc.,
    
    531 U.S. 457
    , 471 (2001), “for the court, as well as the
    agency, must give effect to the unambiguously expressed
    2
    In its briefing and at oral argument, the government made clear that the
    operative definition of “obstruction of justice” is the one the BIA
    announced in Valenzuela Gallardo, so that is the one we review. The
    dissent would have us review a construction that is narrower and more
    concrete than the one the BIA advocates. Dissent at 44. The dissent also
    quarrels with our characterization of the BIA’s interpretation of INA
    § 101(a)(43)(S) as “new,” see Dissent, Section I, but the government did
    not dispute that this is a new interpretation. More to the point, whether the
    BIA’s definition is new, newly clarified, or merely “a change from this
    Circuit’s interpretation of BIA precedent,” Dissent at 33, the BIA in
    Valenzuela Gallardo “invoke[d] . . . Brand X” and set out the operative
    construction of “obstruction of justice.” Valenzuela Gallardo, 25 I. & N.
    Dec. at 840. “Under Brand X,” it is our duty to review “the BIA’s most
    recent interpretation.” Anaya-Ortiz v. Holder, 
    594 F.3d 673
    , 678 (9th Cir.
    2010); see also Chevron, U.S.A., Inc. v. Nat. Res. Def. Council, Inc.,
    
    467 U.S. 837
    , 842 (1984).
    VALENZUELA GALLARDO V. LYNCH                           13
    intent of Congress,” Chevron, 
    467 U.S. at
    842–43. To
    determine whether the statute unambiguously bars an agency
    interpretation we “apply[] the normal ‘tools of statutory
    construction.’” INS v. St. Cyr, 
    533 U.S. 289
    , 320 n.45 (2001)
    (quoting Chevron, 
    467 U.S. at
    843 n.9). If, after application
    of these tools, an immigration statute remains “silent or
    ambiguous with respect to the specific issue before the
    agency,” we proceed to Chevron Step Two and determine
    whether “the BIA’s interpretation is ‘based on a permissible
    construction of the statute.’” Renteria-Morales, 
    551 F.3d at 1081
     (quoting Parrilla v. Gonzales, 
    414 F.3d 1038
    , 1041 (9th
    Cir. 2005)). If it is, the court must defer to the BIA’s
    reasonable statutory interpretation.
    We have deferred to the BIA’s interpretation of
    “obstruction of justice” in at least three cases because the
    INA did not unambiguously bar the interpretation and the
    interpretation was reasonable.3 Hoang, 
    641 F.3d at
    1160–61;
    Salazar-Luviano, 
    551 F.3d at 860
    ; Renteria-Morales,
    3
    Valenzuela Gallardo argues that the BIA cannot depart from our
    court’s decision in Hoang or its own prior interpretation in Espinoza-
    Gonzalez. We disagree. In National Cable & Telecommunications Ass’n
    v. Brand X Internet Services, the Supreme Court expressly instructed that
    “[a] court’s prior judicial construction of a statute trumps an agency
    construction otherwise entitled to Chevron deference only if the prior
    court decision holds that its construction follows from the unambiguous
    terms of the statute and thus leaves no room for agency discretion.”
    
    545 U.S. 967
    , 982 (2005). Because our prior interpretations of
    § 101(a)(43)(S) did not follow unambiguously from the statute, see
    Hoang, 
    641 F.3d at 1161
    , the BIA was free to interpret the phrase
    “obstruction of justice” in a manner inconsistent with those precedents.
    Therefore, “[u]nder Brand X, we must apply Chevron deference to the
    BIA’s most recent interpretation” if Congress has not directly spoken to
    the issue and the BIA’s interpretation is reasonable. Anaya-Ortiz v.
    Holder, 
    594 F.3d 673
    , 678 (9th Cir. 2010).
    14           VALENZUELA GALLARDO V. LYNCH
    551 F.3d at 1086–87; see also INS v. Aguirre-Aguirre,
    
    526 U.S. 415
    , 424 (1999) (“It is clear that principles of
    Chevron deference are applicable to [the INA’s] statutory
    scheme.”). However, our prior deference to the BIA’s
    interpretation of “obstruction of justice” does not end the
    Chevron Step One inquiry. See INS v. Cardoza-Fonseca,
    
    480 U.S. 421
    , 446–48 (1987) (concluding that the BIA’s
    interpretation of “well-founded fear,” an otherwise
    ambiguous term, was inconsistent with the INA at Chevron
    Step One). Rather, before turning to Chevron’s Step Two, we
    must ask whether Congress intended to permit the agency
    interpretation. Food & Drug Admin. v. Brown & Williamson
    Tobacco Corp., 
    529 U.S. 120
    , 159 (2000). To answer this
    question we are aided by traditional tools of statutory

    , 575 (1988). The dissent objects to our
    use of constitutional narrowing to interpret the INA, arguing
    that we should stick with “the familiar Chevron standard.”
    Dissent at 34. But Chevron itself instructs that “employing
    traditional tools of statutory construction” is a straightforward
    application of Chevron. Chevron, 
    467 U.S. at

    Indeed, the canon of constitutional avoidance “is highly
    relevant at Chevron step one.” Morales-Izquierdo v.

    Chevron Step Two).4 Because we “assum[e] that Congress
    does not casually authorize administrative agencies to
    interpret a statute to push the limit of congressional
    authority,” if an agency’s statutory interpretation “invokes the
    outer limits of Congress’ power, we expect a clear indication

    The dissent criticizes our mode of Chevron analysis and the use of the
    doctrine of constitutional avoidance at Chevron Step One. See Dissent at
    47–48 (quoting Olmos v. Holder, 
    780 F.3d 1313
    , 1320–21 (10th Cir.
    2015)). The dissent is incorrect, however, that we only ask whether
    Congress intended an implicit delegation in “extraordinary cases.” See
    Chevron, 
    467 U.S. at
    843–44 (directing courts to determine whether
    Congress explicitly or implicitly delegated authority to an agency);
    Dissent at 49–50. Rather, when read in context, the cases invoked by the
    dissent stand for the proposition that we should hesitate to find an implicit
    delegation in “extraordinary cases” of “economic and political
    significance.” King v. Burwell, 
    135 S. Ct. 2480
    , 2489 (2015) (emphasis
    added) (concluding that the potential implicit delegation at issue was of
    such “deep economic and political significance” that “had Congress
    wished to assign that question to an agency, it surely would have done so
    expressly”); Brown & Williamson, 
    529 U.S. at
    159–60 (concluding that
    “Congress could not have intended to delegate a decision of such
    economic and political significance to an agency in so cryptic a fashion”).
    Here, where the potential implicit delegation is not one of deep “economic
    and political significance,” we must turn to other tools to assess
    Congressional intent, such as the constitutional avoidance doctrine.
    Furthermore, even the dissent acknowledges that the Supreme Court
    applies the constitutional avoidance doctrine in the Chevron context,
    Dissent at 63–65; DeBartolo, 
    485 U.S. at
    575–76, and our en banc
    authority says that the doctrine is inapplicable at Step Two, Morales-
    Izquierdo, 
    486 F.3d at
    492–93. That leaves Step One, lest we abdicate our
    role.

    questionable interpretation. Williams v. Babbit, 
    115 F.3d 657
    , 662–63 (9th Cir. 1997); see also DeBartolo, 
    485 U.S. at 588
     (construing the NLRA to preclude an interpretation
    raising grave constitutional concerns rather than deferring to
    the agency interpretation).
    The use of constitutional narrowing in the Chevron
    context is not a novel concept. The Supreme Court and our
    court have refused to accord deference to agency
    interpretations that raise grave constitutional doubts where
    other permissible and less troubling interpretations exist. In
    DeBartolo Corp. v. Florida Gulf Coast Building &
    Construction Trades Council, 
    485 U.S. 568
     (1988), the
    Supreme Court announced the applicability of the
    constitutional avoidance doctrine in the Chevron context.
    DeBartolo concerned the National Labor Relations Board’s
    (NLRB) interpretation of “coercion” as used in the National
    Labor Relations Act (NLRA). The NLRB decided that a
    labor union’s peaceful handbilling of consumers was
    prohibited if it encouraged consumers to boycott stores that
    failed to pay fair wages. 
    Id. at 573
    . The Court held that
    though the interpretation would otherwise be entitled to
    Chevron deference, the NLRB’s interpretation posed serious
    questions of validity under the First Amendment. 
    Id.
     at
    574–76. The Court invoked the constitutional avoidance
    doctrine: “where an otherwise acceptable construction of a
    statute would raise serious constitutional problems, the Court
    will construe the statute to avoid such problems unless such
    construction is plainly contrary to the intent of Congress.” 
    Id.
    at 575 (citing NLRB v. Catholic Bishop of Chi., 
    440 U.S. 490
    ,
    499–501 (1979)). The DeBartolo Court observed:
    “[T]he elementary rule is that every
    reasonable construction must be resorted to,
    VALENZUELA GALLARDO V. LYNCH                   17
    in order to save a statute from
    unconstitutionality.” This approach not only
    reflects the prudential concern that
    constitutional issues not be needlessly
    confronted, but also recognizes that Congress,
    like this Court, is bound by and swears an
    oath to uphold the Constitution. The courts
    will therefore not lightly assume that
    Congress intended to infringe constitutionally
    protected liberties or usurp power
    constitutionally forbidden it.
    
    Id.
     (quoting Hooper v. California, 
    155 U.S. 648
    , 657 (1895)).
    The Court ultimately determined that a less
    constitutionally suspect interpretation was not foreclosed by
    the statutory language or legislative history. It therefore
    declined to defer to the NLRB’s interpretation because a less
    problematic construction “makes unnecessary passing on the
    serious constitutional questions that would be raised by the
    Board’s understanding of the statute.” Id. at 588.
    In Rust v. Sullivan, 
    500 U.S. 173
     (1991), the Supreme
    Court further refined its application of the constitutional
    avoidance doctrine to agency interpretation of ambiguous
    statutes. The Rust Court reviewed facial challenges to
    regulations promulgated by the Secretary of Health and
    Human Services under Title X of the Public Health Service
    Act. 
    Id. at 181
    . Because the regulations provided that funds
    under the Act could not be used to pay for abortions, directly
    or indirectly, the challengers claimed the regulation violated
    the First and Fifth Amendments. 
    Id.
     The Court observed that
    the principle espoused in DeBartolo “is based at least in part
    on the fact that a decision to declare an Act of Congress
    18          VALENZUELA GALLARDO V. LYNCH
    unconstitutional ‘is the gravest and most delicate duty that
    this Court is called on to perform,’” 
    id.
     at 190–91 (quoting
    Blodgett v. Holden, 
    275 U.S. 142
    , 148 (1927)), and concluded
    that a “statute must be construed, if fairly possible, so as to
    avoid not only the conclusion that it is unconstitutional but
    also grave doubts upon that score.” 
    Id.
     (quoting United States
    v. Jin Fuey Moy, 
    241 U.S. 394
    , 401 (1916)). Applying this
    rule, the Court held that the public health regulations at issue
    in Rust did not “raise the sort of ‘grave and doubtful
    constitutional questions’ that would lead [it] to assume
    Congress did not intend to authorize their issuance,” and
    declined to invalidate the regulations. 
    Id.
     (citation omitted).
    Our court considered DeBartolo and Rust in Williams v.
    Babbitt, 
    115 F.3d 657
     (9th Cir. 1997). There, we synthesized
    and applied the DeBartolo-Rust constitutional avoidance
    standard for the first time. 
    Id.
     at 661–63. The Babbitt court
    reviewed an interpretation by the Interior Board of Indian
    Appeals (IBIA) of the Reindeer Industry Act as it pertained
    to reindeer sales in Alaska. 
    Id. at 659
    . The IBIA interpreted
    the Act to prohibit non-Natives from joining the Alaska
    reindeer industry. 
    Id.
     On appeal, non-Native appellants
    claimed that the IBIA interpretation violated the
    constitutional guarantee of equal protection. 
    Id. at 660
    .
    Our analysis in Babbitt began by observing that the IBIA
    interpretation was entitled to Chevron deference “absent other
    considerations.” 
    Id.
     at 660 n.3. We then went on to analyze
    one of those “other considerations,” namely, whether the
    interpretation raised equal protection concerns. 
    Id. at 661
    .
    We concluded: “Rust and DeBartolo, read together, require
    courts to scrutinize constitutional objections to a particular
    agency interpretation skeptically. Only if the agency’s
    proffered interpretation raises serious constitutional concerns
    VALENZUELA GALLARDO V. LYNCH                     19
    may a court refuse to defer under Chevron.” 
    Id. at 662
    .
    Because we concluded that the IBIA’s interpretation of the
    Reindeer Act raised serious constitutional concerns, and
    because “a less constitutionally troubling construction [was]
    readily available,” we interpreted the Act as not precluding
    non-Natives from owning and importing reindeer in Alaska.
    
    Id. at 666
    .
    When a court practices what Babbitt termed
    “constitutional narrowing,” it leaves agencies “free to adopt
    any interpretation that doesn’t come perilously close to the
    constitutional boundary.” 
    Id.
     at 662–63. Constitutional
    narrowing recognizes that the decision to foreclose a
    constitutionally troubling interpretation is a legal decision,
    not a policy decision, and should be addressed by the courts,
    not the agency. 
    Id. at 662
    . Agencies specialize in making the
    policy decisions necessary to apply generalized statutory
    provisions to the complexities of everyday life. FDA v.
    Brown & Williamson, 
    529 U.S. 120
    , 132–33 (2000). Judges
    specialize in “say[ing] what the law is.” Marbury v.
    Madison, 5 U.S. (1 Cranch) 137, 177 (1803). “[W]hen a
    court construes a statute so as to avoid a difficult
    constitutional question, it is not making a policy choice,” it is
    making a legal choice. Babbit, 
    115 F.3d at 662
    . The policy
    choice remains with the agency, which is “free to adopt any
    interpretation that doesn’t come perilously close to the
    constitutional boundary.” 
    Id. at 663
    .
    These authorities establish that where an agency’s
    interpretation of a statute raises grave constitutional concerns,
    and where Congress has not clearly indicated it intends a
    constitutionally suspect interpretation, we can assume
    Congress did not delegate authority for the interpretation and
    20           VALENZUELA GALLARDO V. LYNCH
    deem it foreclosed by the statute. With this framework in
    mind, we turn to the agency interpretation before us.
    III.    The BIA’s new interpretation raises grave
    constitutional doubts.
    The BIA has been express in stating that it does “not
    believe that every offense that, by its nature, would tend to
    ‘obstruct justice’ is an offense that should properly be
    classified as ‘obstruction of justice.’” In re Espinoza-
    Gonzalez, 
    22 I. & N. Dec. 889
    , 893–94 (B.I.A. 1999). And
    the BIA has given some indication of where it draws that line:
    
    18 U.S.C. § 3
     (accessory after the fact) is an obstruction of
    justice crime, whereas 
    18 U.S.C. § 4
     (misprision of felony) is
    not. 
    Id. at 892
    . According to the BIA, the distinction
    between these crimes—and the “critical element” of
    obstruction of justice crimes—is the “affirmative and
    intentional attempt, motivated by a specific intent, to interfere
    with the process of justice,” regardless of the existence of an
    ongoing investigation or proceeding. In re Valenzuela
    Gallardo, 
    25 I. & N. Dec. 838
    , 842 (B.I.A. 2012). In other
    words, though the BIA has said that not every crime that
    tends to obstruct justice qualifies as an obstruction of justice
    crime, and the critical factor is the interference with the
    process of justice—which does not require an ongoing
    investigation or proceeding—the BIA has not given an
    indication of what it does include in “the process of justice,”
    or where that process begins and ends. Valenzuela Gallardo
    argues that this new interpretation raises grave doubts about
    whether INA § 101(a)(43)(S) is unconstitutionally vague.
    We agree.
    “The Fifth Amendment provides that ‘[n]o person shall
    . . . be deprived of life, liberty, or property, without due
    VALENZUELA GALLARDO V. LYNCH                     21
    process of law.’” Johnson v. United States, 
    135 S. Ct. 2551
    ,
    2556 (2015) (alterations in original) (quoting U.S. Const.
    amend. V). The “[v]agueness doctrine is an outgrowth . . . of
    [that clause]. A conviction fails to comport with due process
    if the statute under which it is obtained fails to provide a
    person of ordinary intelligence fair notice of what is
    prohibited, or is so standardless that it authorizes or
    encourages seriously discriminatory enforcement.” United
    States v. Williams, 
    553 U.S. 285
    , 304 (2008). The Supreme
    Court has advised:
    What renders a statute vague is not the
    possibility that it will sometimes be difficult
    to determine whether the incriminating fact it
    establishes has been proved; but rather the
    indeterminancy of precisely what that fact is.
    Thus, we have struck down statutes that tied
    criminal culpability to . . . wholly subjective
    judgments without statutory definitions,
    narrowing context, or settled legal meanings.
    
    Id. at 306
     (emphasis added). “The prohibition of vagueness
    in criminal statutes ‘is a well-recognized requirement,
    consonant alike with ordinary notions of fair play and the
    settled rules of law,’ and a statute that flouts it ‘violates the
    first essential of due process.’” Johnson, 
    135 S. Ct. at
    2556–57 (quoting Connally v. Gen. Constr. Co., 
    269 U.S. 385
    , 391 (1926)).
    Recently, the Supreme Court held that the residual clause
    of the Armed Career Criminal Act of 1984 is
    unconstitutionally vague because it “denies fair notice to
    defendants and invites arbitrary enforcement by judges.” Id.
    at 2257. The residual clause states that a “violent felony” is
    22           VALENZUELA GALLARDO V. LYNCH
    “any crime punishable by imprisonment for a term exceeding
    one year . . . that . . . involves conduct that presents a serious
    potential risk of physical injury to another.” 
    18 U.S.C. § 924
    (e)(2)(B). The Court held that two features of the clause
    render it unconstitutionally vague. First, the clause “leaves
    grave uncertainty about how to estimate the risk posed by a
    crime. It ties the judicial assessment of risk to a judicially
    imagined ordinary case of a crime, not to real-world facts or
    statutory elements.” Johnson, 
    135 S. Ct. at 2557
     (internal
    quotation marks omitted). Second, the clause creates
    “uncertainty about how much risk it takes for a crime to
    qualify as a violent felony. It is one thing to apply an
    imprecise ‘serious potential risk’ standard to real-world facts;
    it is quite another to apply it to a judge-imagined abstraction.”
    
    Id. at 2558
    . The Supreme Court concluded: “By combining
    indeterminacy about how to measure the risk posed by a
    crime with indeterminacy about how much risk it takes for
    the crime to qualify as a violent felony, the residual clause
    produces more unpredictability and arbitrariness than the Due
    Process Clause tolerates.” 
    Id.
    The residual clause left grave uncertainty about the
    amount of risk it takes for a crime to qualify as a violent
    felony. The BIA’s new construction leaves grave uncertainty
    about the plethora of steps before and after an “ongoing
    criminal investigation or trial” that comprise “the process of
    justice,” and, hence, uncertainty about which crimes
    constitute “obstruction of justice.” See In re Valenzuela
    Gallardo, 
    25 I. & N. Dec. 838
    , 841 (B.I.A. 2012). We can
    glean no definition of “the process of justice” from the BIA’s
    case law. See, e.g., 
    id.
     at 840–41 (distinguishing 
    18 U.S.C. § 4
     (misprision of felony) from 
    18 U.S.C. § 3
     (accessory after
    VALENZUELA GALLARDO V. LYNCH                              23
    the fact) based on § 3’s specific intent requirement).5 The
    phrase “obstruction of justice” has no statutory definition or
    settled legal meaning. See 
    8 U.S.C. § 1101
     (INA definitions
    section with no definition of “process of justice”); Black’s
    Law Dictionary 1329 (9th ed. 2009) (providing no definition
    of “process of justice”). When the BIA clarified that the
    “process of justice” does not necessarily involve an ongoing
    investigation or proceeding, it eliminated the narrowing
    principal Hoang had gleaned from earlier BIA case law. See
    Trung Thanh Hoang v. Holder, 
    641 F.3d 1157
    , 1160–61,
    1164 (9th Cir. 2011). We do not hold, as the dissent suggests,
    that “ongoing proceedings” is the only permissible anchor for
    the “process of justice.” But after Valenzuela Gallardo,
    arguably everything that happens after someone commits a
    crime could be considered to be part of the “process of
    justice.” We cannot reconcile this expansive interpretation
    with the BIA en banc court’s declaration that it does “not
    believe that every offense that, by its nature, would tend to
    ‘obstruct justice’ is an offense that should properly be
    classified as ‘obstruction of justice.’” In re Espinoza-
    Gonzalez, 
    22 I. & N. Dec. 889
    , 893–94 (B.I.A. 1999). As the
    Supreme Court noted in Williams, amorphous terms “without
    statutory definitions, narrowing context, or settled legal
    5
    At oral argument, the government would only go so far as to say that
    interference with the “process of justice” includes interfering with another
    person’s arrest or apprehension. This only confirms that a conviction
    under California’s accessory after the fact statute is a crime “relating to
    the obstruction of justice.” See 
    Cal. Penal Code § 32
     (“Every person who,
    after a felony has been committed . . . aids a principal in such felony, with
    the intent that such principal may avoid escape from arrest, trial,
    conviction or punishment . . . is an accessory to such felony.”). The
    government’s response does not provide a limiting principal or tell us
    what crimes—other than § 32—fall within and outside the nebulous
    “process of justice.”
    24          VALENZUELA GALLARDO V. LYNCH
    meanings” raise vagueness concerns. See United States v.
    Williams, 
    553 U.S. 285
    , 306 (2008).
    Absent some indication of the contours of “process of
    justice,” an unpredictable variety of specific intent crimes
    could fall within it, leaving us unable to determine what
    crimes make a criminal defendant deportable under INA
    § 101(a)(43)(S) and what crimes do not. See City of Chicago
    v. Morales, 
    527 U.S. 41
    , 57 (1999) (plurality opinion)
    (invalidating as unconstitutionally vague Chicago’s anti-
    loitering statute in part because it did not give potential
    violators notice of “what loitering is covered by the ordinance
    and what is not”). More importantly, because the BIA’s new
    interpretation invites arbitrary enforcement, defense lawyers
    will be unable to accurately advise their clients about the
    immigration-related consequences of a conviction or plea
    agreement. See Padilla v. Kentucky, 
    559 U.S. 356
    , 360
    (2010) (holding that defense “counsel had an obligation to
    advise [defendant] that the offense to which he was pleading
    guilty would result in his removal from this country”).
    What we do know is that, in the INA, Congress identified
    three types of obstruction-related offenses that qualify as
    “aggravated felonies” and trigger deportation: “[1] an offense
    relating to obstruction of justice, [2] perjury or subordination
    of perjury, [3] or bribery of a witness.” INA § 101(a)(43)(S).
    Perjury and bribery of a witness are clearly tied to
    proceedings, and this informs our understanding of
    Congress’s intended interpretation of “obstruction of justice.”
    See Microsoft Corp. v. C.I.R., 
    311 F.3d 1178
    , 1184 (9th Cir.
    2002) (“The doctrine of noscitur a sociis counsels that words
    should be understood by the company they keep.”). Shedding
    more light on what Congress intended is the list of
    obstruction of justice crimes Congress included in Title 18,
    VALENZUELA GALLARDO V. LYNCH                             25
    Chapter 73, on which the BIA based its interpretation of INA
    § 101(a)(43)(S). See Espinoza-Gonzalez, 22 I. & N. Dec. at
    892. The difficulty presented by the BIA’s new interpretation
    of “obstruction of justice” can be seen by comparing it to the
    Chapter 73 obstruction of justice crimes. As the BIA has
    recognized, almost all of these “obstruction of justice
    offenses . . . have as an element interference with the
    proceedings of a tribunal.” Id. at 892. The few that do not
    require interference with a tribunal or investigation have as an
    element the intent to interfere with a specific act associated
    with a tribunal or investigation. See, e.g., 
    18 U.S.C. § 1512
    (b)(3) (prohibition on tampering with a witness with
    the intent to hinder or prevent “communication to a law
    enforcement officer” regarding a federal offense); 
    18 U.S.C. § 1512
    (d)(2) (prohibition on harassing someone with the
    intent to prevent that person from “reporting [a federal crime]
    to a law enforcement officer or judge”); 
    18 U.S.C. § 1519
    (prohibition on falsifying or destroying a record “with the
    intent to impede, obstruct, or influence the investigation or
    proper administration of any matter” within the jurisdiction
    of the United States).6
    The Government and dissent assure us that the BIA’s new
    interpretation is sufficiently limited because it still requires
    6
    The dissent discusses examples of crimes that clearly fall within the
    BIA’s new interpretation, but we are concerned with the outer edges of the
    definition, not its core. The fact that the BIA’s interpretation encompasses
    conduct Congress undoubtedly intended to include in “obstruction of
    justice,” see 
    18 U.S.C. §§ 1501
    –1521, does not resolve the due process
    concern presented by the phrase “the process of justice.” In Johnson, the
    Supreme Court reaffirmed that its case law “squarely contradict[s] the
    theory that a vague provision is constitutional merely because there is
    some conduct that clearly falls within the provision’s grasp.” 135 S. Ct.
    at 2561.

    specific intent. But this does little to answer the question
    central to our constitutional concerns—specific intent to do
    what? See United States v. Williams, 
    553 U.S. 285
    , 306
    (2008) (“What renders a statute vague, however, is not the
    possibility that it will sometimes be difficult to determine
    whether the incriminating fact it establishes has been proved;
    but rather the indeterminancy of precisely what that fact is.”
    (emphasis added)). Though it ostensibly defines the required
    mens rea—intent to interfere with the “process of justice”—it
    provides little instruction on the equally important actus reus.
    Cf. Leal v. Holder, 
    771 F.3d 1140
    , 1146 (9th Cir. 2014)
    (“[B]oth the actus reus and the mens rea must be considered
    in concert to determine whether the behavior they describe is
    sufficiently culpable.” (citation omitted)); Trung Thanh
    Hoang v. Holder, 
    641 F.3d 1157
    , 1161 (9th Cir. 2011)
    (“Espinoza-Gonzalez ‘articulated both an actus reus and mens
    rea element of the generic definition of [obstruction of
    justice] crimes for purposes of §1101(a)(43)(S).’” (alteration
    in original) (citation omitted)). Specific intent does little to
    accord fair notice when there is no indication of what it is that
    must be interfered with in order to “obstruct justice.”
    The Government also argues that the one-year sentence
    requirement offers a limitation on its interpretation. See INA
    § 101(a)(43)(S). But as with the specific intent element, the
    one-year sentence requirement does not reduce the
    indeterminacy of the type of conduct that qualifies as an
    aggravated felony. Indeed, in the context of accessory after
    the fact, the one-year sentence actually reflects the severity of
    an underlying crime committed by another person. The
    residual clause the Supreme Court examined in Johnson also
    required a one-year sentence. 135 S. Ct. at 2555. There, the
    sentence at least reflected the crime actually committed by
    the defendant at issue, see 
    18 U.S.C. § 924
    (e)(2)(B) (“[T]he
    VALENZUELA GALLARDO V. LYNCH                             27
    term ‘violent felony’ means any crime punishable by
    imprisonment for a term exceeding one year.”), but even so,
    the length-of-sentence limitation was insufficient to salvage
    the clause from its vagueness. See Johnson, 
    135 S. Ct. at 2563
    . We see no reason for concluding that the same one-
    year sentence requirement is sufficient to dispel the serious
    constitutional doubts presented here.
    The dissent reads our opinion as imposing a “temporal
    nexus requirement” on the BIA’s definition of “crimes
    relating to obstruction of justice.” Dissent at 36. It doesn’t.
    We do not hold that the BIA’s definition of “obstruction of
    justice” must be tied to an ongoing proceeding; rather, we
    hold that the BIA’s new interpretation of obstruction of
    justice raises grave constitutional concerns because it uses an
    amorphous phrase—“process of justice”—without telling us
    what that phrase means. It is difficult to imagine a specific
    intent crime that could not be swept into the BIA’s expanded
    definition. The problem is the absence of any narrowing
    context—not necessarily the specific narrowing context of a
    tie to “ongoing proceedings.”7 The BIA is free to define
    7
    The dissent argues that “the BIA’s definition is not missing the
    required nexus” to “a foreseeable or contemplated proceeding,” Dissent
    at 52–53, and suggests that the BIA’s interpretation of “obstruction of
    justice” requires a nexus to an ongoing or contemplated proceeding or
    investigation. But this is not what the BIA said in Valenzuela Gallardo
    or in oral argument before our court. In Valenzuela Gallardo, the BIA
    articulated that “the existence of such proceedings is not an essential
    element of ‘an offense relating to obstruction of justice.’” 25 I. & N. Dec.
    at 841. If, as the dissent suggests, the BIA intends interference with the
    “process of justice” to mean interference with an ongoing or foreseeable
    or contemplated investigation or proceeding, it can clarify this on remand.
    28             VALENZUELA GALLARDO V. LYNCH
    obstruction of justice as it sees fit on remand, as long as the
    definition is not unworkably vague.8
    IV.      Under the constitutional avoidance doctrine, we do
    not defer to the BIA’s new construction.
    Having determined that the BIA’s new interpretation
    creates serious constitutional doubts, we must determine
    whether Congress “[made] it clear that it chooses the
    constitutionally doubtful interpretation.” Williams v. Babbitt,
    8
    The dissent argues that we create or exacerbate a circuit split with the
    Second, Third, Fifth, and Eighth Circuits. See Dissent at 44–45 & n.6.
    We don’t. Our sister circuits do not address whether the BIA’s
    interpretation of “obstruction of justice” is unconstitutionally vague in any
    of the cases cited by the dissent. See Armenta-Lagunas v. Holder, 
    724 F.3d 1019
    , 1020–21 (8th Cir. 2013); Higgins v. Holder, 
    677 F.3d 97
    ,
    98–99 (2d Cir. 2012) (per curiam); Denis v. Attorney General, 
    633 F.3d 201
    , 207–09 (3d Cir. 2011). “Nexus to an ongoing proceeding” was not
    at issue in Armenta-Lagunas or Higgins because the state statutes in those
    cases plainly required such a nexus. See Armenta-Lagunas, 724 F.3d at
    1023; Higgins, 
    677 F.3d at 105
     (noting that the Connecticut statute
    “require[s] a nexus to an official proceeding”). In United States v.
    Gamboa-Garcia, 
    620 F.3d 546
     (5th Cir. 2010)—a case decided before
    Valenzuela Gallardo and Descamps v. United States, 
    133 S. Ct. 2276
    (2013)—the Fifth Circuit relied on the alien’s conduct, not the elements
    of her crime of conviction, to decide that the crime “relat[ed] to
    obstruction of justice.” Gamboa-Garcia, 
    620 F.3d at
    549–50. The
    conduct was extreme: Gamboa-Garcia witnessed a murder, drove and
    cleaned up the getaway car, financed the murderer’s escape, and lied to
    police. 
    Id. at 547
    . The dissent also overlooks that our circuit has long
    disagreed with the Third Circuit’s interpretation of INA § 101(a)(43)(S).
    In fact, our circuits’ views depart from the get-go because the Third
    Circuit does not even consider the undefined term “obstruction of justice”
    to be ambiguous. See Denis, 
    633 F.3d at
    207–09, 211 & n.12 (“[W]e
    again depart from the view adopted by the Ninth and Fifth Circuit Courts
    of Appeals . . . .”). Contrary to the dissent’s assertion, our decision does
    not create or exacerbate a circuit split.
    VALENZUELA GALLARDO V. LYNCH                     29
    
    115 F.3d 657
    , 663 (9th Cir. 1997). We see no such
    indication.     All of Congress’s express examples of
    obstruction of justice contemplate ongoing proceedings or
    investigations or are otherwise sufficiently specific to provide
    notice of what conduct is prohibited. See 
    18 U.S.C. §§ 1501
    –1502, 1504–1521; supra Section III. And although
    the catchall provision in 
    18 U.S.C. § 1503
     pertains to anyone
    who “influences, obstructs, or impedes, or endeavors to
    influence, obstruct, or impede, the due administration of
    justice,” courts have universally construed this broad
    language to require an ongoing proceeding:
    Recent decisions of Courts of Appeals have
    likewise tended to place metes and bounds on
    the very broad language of the catchall
    provision. The action taken by the accused
    must be with an intent to influence judicial or
    grand jury proceedings; it is not enough that
    there be an intent to influence some ancillary
    proceeding, such as an investigation
    independent of the court’s or grand jury’s
    authority. United States v. Brown, 
    688 F.2d 596
    , 598 (9th Cir. 1982) (citing cases). Some
    courts have phrased this showing as a
    “nexus” requirement—that the act must have
    a relationship in time, causation, or logic with
    the judicial proceedings. United States v.
    Wood, 
    6 F.3d 692
    , 696 (10th Cir. 1993);
    United States v. Walasek, 
    527 F.2d 676
    , 679
    & n.12 (3d Cir. 1975). In other words, the
    endeavor must have the “‘natural and
    probable effect’” of interfering with the due
    administration of justice. Wood, 
    6 F.3d at 695
    ; United States v. Thomas, 
    916 F.2d 647
    ,
    30             VALENZUELA GALLARDO V. LYNCH
    651 (11th Cir. 1990); Walasek, 
    527 F.2d at 679
    . . . . But . . . if the defendant lacks
    knowledge that his actions are likely to affect
    the judicial proceeding, he lacks the requisite
    intent to obstruct.
    United States v. Aguilar, 
    515 U.S. 593
    , 599 (1995) (emphasis
    added); see also In re Espinoza-Gonzalez, 
    22 I. & N. Dec. 889
    , 892 (B.I.A. 1999) (noting that the Supreme Court has
    “narrowly” construed the catchall provision).9 As the BIA
    itself observed in Espinoza-Gonzalez, even the broadest
    obstruction of justice provisions intend “to protect individuals
    assisting in a federal investigation or judicial proceeding and
    to prevent a miscarriage of justice in any case pending in a
    federal court.” 22 I. & N. Dec. at 892. We see no indication
    Congress intended that “obstruction of justice” be interpreted
    as broadly as the BIA has done here.
    9
    Judicial interpretations of § 1503 are particularly relevant here because
    the BIA’s construction pertains to a criminal statute, where federal
    courts—not administrative agencies—have expertise. See Leocal v.
    Ashcroft, 
    543 U.S. 1
    , 11 n.8 (2004) (“Although here we deal with
    [18 U.S.C.] § 16 in the deportation context, § 16 is a criminal statute, and
    it has both criminal and noncriminal applications. Because we must
    interpret the statute consistently, whether we encounter its application in
    a criminal or noncriminal context, the rule of lenity applies.”); Mugalli v.
    Ashcroft, 
    258 F.3d 52
    , 56 (2d Cir. 2001) (“But the BIA’s conclusion that
    a conviction under 
    18 U.S.C. § 513
    (a) necessarily constituted an ‘attempt’
    as the BIA had defined it depended on an analysis of a federal criminal
    statute and was thus beyond the BIA’s administrative responsibility and
    expertise. That conclusion was therefore entitled to no deference from
    us.” (emphasis added)). Because the BIA has expertise in interpreting the
    INA, but not the federal criminal code, there is less reason to defer. See,
    e.g., Carachuri-Rosendo v. Holder, 
    560 U.S. 563
     (2010) (striking down
    BIA interpretation of aggravated felony provision without mentioning
    Chevron deference).
    VALENZUELA GALLARDO V. LYNCH                     31
    Further, and contrary to the dissent’s argument, the fact
    that Congress defined “aggravated felony” to include not just
    obstruction of justice offenses but offenses “relating to
    obstruction of justice” does not indicate its intent that the BIA
    “push the constitutional envelope.” Williams v. Babbit,
    
    115 F.3d 657
    , 662 (9th Cir. 1997). The use of the modifier
    “relating to” broadens the INA’s intended reach, but it is not
    an explicit indication that Congress intended that the BIA
    approach the constitutional boundary, nor is it an excuse for
    abdicating our role. See Mellouli v. Lynch, 
    135 S. Ct. 1980
    ,
    1990 (2015) (striking down the BIA’s interpretation of an
    aggravated felony “relating to a controlled substance,” INA
    § 237(a)(2)(B)(I), as inconsistent with congressional intent).
    If Congress wishes to authorize such a result, “it must do so
    explicitly.” Babbitt, 
    115 F.3d at 662
    .
    For over a decade, we upheld the interpretation that the
    BIA announced in Espinoza-Gonzalez—requiring a nexus to
    an ongoing proceeding—as a plausible construction. See
    Trung Thanh Hoang v. Holder, 
    641 F.3d 1157
    , 1161, 1164
    (9th Cir. 2011); Salazar-Luviano v. Mukasey, 
    551 F.3d 857
    ,
    860 (9th Cir. 2008); Renteria-Morales v. Mukasey, 
    551 F.3d 1076
    , 1086–87 (9th Cir. 2008). This demonstrates that “a
    less constitutionally troubling construction is readily
    available.” See Babbitt, 
    115 F.3d at 666
    . We do not
    independently inquire into another interpretation, see
    DeBartolo Corp. v. Fla. Gulf Coast Bldg. & Constr. Trades
    Council, 
    485 U.S. 568
    , 577 (1988); we leave it to the BIA to
    “adopt any interpretation that doesn’t come perilously close
    to the constitutional boundary.” See Babbitt, 
    115 F.3d at 663
    .
    “And, of course, Congress may . . . remov[e] the statutory
    ambiguity and mak[e] it clear that it chooses the
    constitutionally doubtful interpretation—in which event, the
    32          VALENZUELA GALLARDO V. LYNCH
    courts will have to confront the constitutional question
    squarely.” 
    Id.
    Our decision to remand to the BIA, rather than attempt to
    reconcile the questions that arise from the interpretation its
    three-judge panel announced in Valenzuela Gallardo, is
    consistent with the charge from Congress that the BIA
    administer the INA. See Gonzalez v. Thomas, 
    547 U.S. 183
    ,
    186 (2006) (per curiam). It is also consistent with the
    government’s request in its supplemental briefing that the
    court remand for the Board to provide an alternative
    definition of the ambiguous statute if we agree with the
    petitioner’s view of this one.
    We remand to the agency so that it can either offer a new
    construction of INA § 101(a)(43)(S) or, in the alternative,
    apply Espinoza-Gonzalez’s interpretation to the instant case.
    CONCLUSION
    We grant Valenzuela Gallardo’s petition for review and
    remand to the BIA for proceedings consistent with this
    opinion.
    PETITION GRANTED AND REMANDED.
    VALENZUELA GALLARDO V. LYNCH                           33
    SEABRIGHT, District Judge, dissenting:
    For several reasons, I respectfully disagree with the
    majority Opinion, and dissent.
    I. Overview
    First, In re Valenzuela Gallardo, 
    25 I. & N. Dec. 838
    (B.I.A. 2012), did not announce a new Board of Immigration
    Appeals (“BIA”) interpretation that removed a required nexus
    between an obstructive act and an existing proceeding,
    thereby rendering its interpretation vague. The majority
    Opinion concludes that Valenzuela Gallardo raises grave
    constitutional vagueness concerns by changing a well-settled
    BIA construction, and gives the BIA an option of applying its
    “previous interpretation” on remand. But the majority
    Opinion relies on a mistaken premise that In re Espinoza-
    Gonzalez, 
    22 I. & N. Dec. 889
     (B.I.A. 1999) (en banc),
    previously required a nexus to an ongoing investigation or
    proceeding for a crime of conviction to be “an offense
    relating to obstruction of justice” for purposes of 
    8 U.S.C. § 1101
    (a)(43)(S).1 In fact, Espinoza-Gonzalez did not (and
    Valenzuela Gallardo explains why). Valenzuela Gallardo is
    not a change from BIA precedent – it is a change from this
    Circuit’s interpretation of BIA precedent.
    As explained to follow, Valenzuela Gallardo explicitly
    clarified language in Espinoza-Gonzalez, in light of what the
    BIA considers to be the Ninth Circuit’s misreading of BIA
    1
    
    8 U.S.C. § 1101
    (a)(43)(S) provides that “[t]he term ‘aggravated felony’
    means . . . an offense relating to obstruction of justice, perjury or
    subornation of perjury, or bribery of a witness, for which the term of
    imprisonment is at least one year[.]”
    34             VALENZUELA GALLARDO V. LYNCH
    precedent in Hoang v. Holder, 
    641 F.3d 1157
     (9th Cir. 2011).
    Further, Valenzuela Gallardo specifically reaffirmed In re
    Batista-Hernandez, 
    21 I. & N. Dec. 955
     (B.I.A. 1997) (en
    banc), which held that 
    18 U.S.C. § 3
     – a crime that is
    indistinguishable from California Penal Code § 32 which is
    at issue here – is indeed a crime “relating to obstruction of
    justice.”2 Valenzuela Gallardo did not purport to overrule or
    change the BIA’s prior (and still valid) en banc precedent,
    although it surely meant to trump Hoang. And as the
    majority Opinion acknowledges, this is the BIA’s prerogative
    under principles of deference set forth in National Cable &
    Telecommunications Ass’n v. Brand X Internet Services,
    
    545 U.S. 967
    , 982 (2005) (“A court’s prior judicial
    construction of a statute trumps an agency construction
    otherwise entitled to Chevron deference only if the prior court
    decision holds that its construction follows from the
    unambiguous terms of the statute and thus leaves no room for
    agency discretion.”) (applying Chevron, U.S.A., Inc. v.
    Natural Res. Def. Council, Inc., 
    467 U.S. 837
     (1984)).
    Thus, viewed in proper context, the matter should be
    analyzed under the familiar Chevron standard where, given
    a statutory ambiguity, courts defer to an agency’s
    construction of a statute it administers if its construction
    “reflects a plausible reading of the statutory text.” Morales-
    Izquierdo v. Gonzales, 
    486 F.3d 484
    , 493 (9th Cir. 2007) (en
    banc) (discussing and applying Chevron).
    2
    California Penal Code § 32 provides that “[e]very person who, after a
    felony has been committed, harbors, conceals or aids a principal in such
    felony, with the intent that said principal may avoid or escape from arrest,
    trial, conviction or punishment, having knowledge that said principal has
    committed such felony or has been charged with such felony or convicted
    thereof, is an accessory to such felony.”
    VALENZUELA GALLARDO V. LYNCH                     35
    Second, although the majority Opinion acknowledges that
    the term “relating to obstruction of justice” in
    § 1101(a)(43)(S) is ambiguous, it refuses to give deference to
    the BIA’s reasonable, permissible, and plausible formulation
    at Chevron step two. But this type of refusal should be
    reserved for “major” or “extraordinary cases.” See King v.
    Burwell, 
    135 S. Ct. 2480
    , 2488–89 (2015) (explaining that
    deference under Chevron to an agency’s construction of a
    statute that it administers “is premised on the theory that a
    statute’s ambiguity constitutes an implicit delegation from
    Congress to the agency to fill in the statutory gaps. . . . In
    extraordinary cases, however, there may be reason to hesitate
    before concluding that Congress has intended such an implicit
    delegation”) (quoting Food & Drug Admin. v. Brown &
    Williamson Tobacco Corp., 
    529 U.S. 120
    , 159 (2000))
    (emphasis added). And unlike King’s challenge to the Patient
    Protection and Affordable Care Act, this is not an
    extraordinary case.
    Instead of deferring, the majority applies the canon of
    constitutional avoidance because it views the BIA’s
    construction as approaching a constitutional boundary –
    vagueness – a type of interpretation that it believes Congress
    could not have intended. But applying the constitutional
    avoidance doctrine in this instance, where the context calls
    for an ordinary Chevron analysis, allows the exception to
    swallow the rule. See, e.g., Nat’l Mining Ass’n v.
    Kempthorne, 
    512 F.3d 702
    , 711 (D.C. Cir. 2008) (“[W]e do
    not abandon Chevron deference at the mere mention of a
    possible constitutional problem; the argument must be
    serious.”). The BIA’s formulation (whether a crime “includes
    the critical element of an affirmative and intentional attempt,
    motivated by a specific intent, to interfere with the process of
    justice, irrespective of the existence of an ongoing criminal
    36          VALENZUELA GALLARDO V. LYNCH
    investigation or proceeding”) does not raise “grave”
    constitutional vagueness concerns.
    The majority Opinion reasons that without a nexus to an
    existing proceeding or investigation, the BIA’s definition
    fails to indicate the contours of “the process of justice,”
    thereby presenting grave or serious constitutional concerns.
    But many obstruction crimes do not require an ongoing or
    pending proceeding – crimes which are undoubtedly “relating
    to obstruction of justice” (a term indicating that Congress
    specifically intended to broaden – not narrow – the scope of
    qualifying obstruction crimes). Such crimes require a nexus
    only to a foreseeable or contemplated investigation (e.g.,
    
    18 U.S.C. § 1512
    (b)(1)), or to a specific type of proceeding
    (e.g., 
    18 U.S.C. § 1519
    ), or otherwise to “the process of
    justice” such as by hindering or preventing an offender’s
    apprehension or arrest (e.g., 
    18 U.S.C. § 3
    ) and thereby
    materially interfering with the ability to investigate or
    prosecute. That is, there is no temporal nexus requirement.
    The absence of a specific requirement for an ongoing
    investigation or pending proceeding does not render the
    BIA’s definition vague, much less create grave constitutional
    doubts on that score.
    Finally, to the extent the constitutional avoidance doctrine
    can apply to the BIA’s formulation in the current Chevron
    context, we should apply it differently than the majority
    Opinion does. If the BIA’s formulation raises serious
    questions as to vagueness, then – as has been done previously
    – we should construe the agency’s precedent in a readily-
    apparent way that is constitutional, not remand with an option
    for the BIA to apply its previous interpretation. See, e.g.,
    Williams v. Babbitt, 
    115 F.3d 657
    , 666 (9th Cir. 1997) (“The
    constitutional questions raised by the [Interior Board of
    VALENZUELA GALLARDO V. LYNCH                       37
    Indian Appeals’] interpretation are grave . . . . We therefore
    interpret the Reindeer Act as not precluding non-natives in
    Alaska from owning and importing reindeer.”); United States
    v. Stansell, 
    847 F.2d 609
    , 615 (9th Cir. 1988) (“Because a
    reasonable limiting construction can be placed on the
    challenged regulation, we hold that [it] is not substantially
    overbroad.”).
    And the BIA’s formulation can certainly be viewed to
    include a required nexus – short of a pending or ongoing
    investigation. The formulation requires an affirmative
    attempt (i.e., an act), with specific intent, to interfere with the
    process of justice – sufficiently encapsulating the type of
    nexus or connection required in crimes such as 
    18 U.S.C. §§ 1512
    (b)(1), 1519, and 3 (and thus to California Penal Code
    § 32 at issue here). Valenzuela Gallardo also specifically
    refers to acts that clearly constitute obstruction – without a
    pending proceeding or investigation – in giving obvious
    meaning to the phrase “the process of justice.” See 25 I. & N.
    Dec. at 841–42 (referring to acts with intent “to hinder or
    prevent [the principal’s] apprehension, trial or punishment”
    and “that [the] principal may avoid or escape from arrest,
    trial, conviction or punishment”) (emphasis added). And it
    reaffirms its en banc precedent further explaining “the
    process of justice.” See id. at 840 (explaining that obstruction
    occurs with an act meant to “prevent[] the arrest of the
    offender”) (quoting Batista-Hernandez, 21 I & N. Dec. at
    961). We need not remand for further explanation.
    To follow, I explain these points in more detail.

    II. Applying Brand-X, Valenzuela Gallardo clarified prior
    BIA decisions in light of Hoang
    It is undisputed that the Immigration and Nationality Act
    (“INA”) does not provide specific guidance as to the meaning
    of “an offense relating to obstruction of justice” in
    § 1101(a)(43)(S) – that is, the term is ambiguous. See, e.g.,
    Renteria-Morales v. Mukasey, 
    551 F.3d 1076
    , 1086 (9th Cir.
    2008) (“[Section] 1101(a)(43)(S) does not clearly set forth the
    elements of the generic federal crime. Because the INA does
    not define the phrase ‘offense relating to obstruction of
    justice,’ we must determine whether there is any binding
    agency precedent on-point which does define that phrase.”)
    (citations and some quotation marks omitted); Salazar-
    Luviano v. Mukasey, 
    551 F.3d 857
    , 860 (9th Cir. 2008)
    (“Because Congress itself did not define the phrase ‘offense
    relating to obstruction of justice’ in the INA, we defer to the
    BIA’s ‘interpretation of the elements of a generic obstruction
    of justice offense under § 1101(a)(43)(S)[.]”) (citation and
    editorial marks omitted); Hoang, 
    641 F.3d at 1160
     (“Though
    the United States criminal code includes a chapter entitled
    ‘Obstruction of Justice,’ 
    18 U.S.C. §§ 1501
    –1521, it does not
    clearly set forth the elements of a generic federal obstruction
    of justice crime; nor does § 1101(a)(43)(S) provide a generic
    definition. Consequently, we must determine whether the
    agency charged with implementing the INA has defined the
    term.”) (citation and footnote omitted).
    Under Chevron, given an ambiguity in a statute that an
    agency administers, a court “does not impose its own
    construction of the statute, but rather it decides ‘whether the
    agency’s answer is based on a permissible construction of the
    statute.’” Gonzales v. Dep’t of Homeland Sec., 
    508 F.3d 1227
    , 1235 (9th Cir. 2007) (quoting Chevron, 467 U.S. at
    VALENZUELA GALLARDO V. LYNCH                            39
    843). And Brand X “instructed federal courts to defer to
    reasonable agency interpretations of ambiguous statutes, even
    when those interpretations conflict with the prior holding of
    a federal circuit court.” Garfias-Rodriguez v. Holder,
    
    702 F.3d 504
    , 507 (9th Cir. 2012) (en banc) (citing Brand X,
    
    545 U.S. at
    982–83). In other words, “[a] circuit court must
    apply Chevron deference to an agency’s interpretation of a
    statute regardless of the circuit court’s contrary precedent,
    provided that the court’s earlier precedent was an
    interpretation of a statutory ambiguity.” Gonzales, 
    508 F.3d at
    1235–36 (citing Brand X, 
    545 U.S. at
    980–82).
    In 2011, a majority in Hoang (over a dissent from Judge
    Bybee) interpreted BIA precedent regarding § 1101(a)(43)(S)
    to require a pending proceeding or investigation such that a
    Washington crime of rendering criminal assistance is not an
    offense “relating to obstruction of justice.” 
    641 F.3d at
    1162–64. Hoang thus concluded that the Washington statute
    was categorically not an aggravated felony because it
    potentially criminalized the rendering of criminal assistance
    “before any investigation or judicial proceeding has begun.”
    
    641 F.3d at 1162
    . It did so, however, despite an en banc BIA
    decision, Batista-Hernandez, which held that a conviction of
    
    18 U.S.C. § 3
     (accessory after the fact) “clearly relates to
    obstruction of justice.” 21 I. & N. Dec. at 961.3 Batista-
    Hernandez cited “the wording of 
    18 U.S.C. § 3
    ” and caselaw
    reasoning that “the nature of being an accessory after the fact
    3
    
    18 U.S.C. § 3
     (“Accessory after the fact”) provides in pertinent part:
    Whoever, knowing that an offense against the United
    States has been committed, receives, relieves, comforts
    or assists the offender in order to hinder or prevent his
    apprehension, trial or punishment, is an accessory after
    the fact.
    40              VALENZUELA GALLARDO V. LYNCH
    lies essentially in obstructing justice and preventing the arrest
    of the offender.” 
    Id.
     (citing United States v. Barlow, 
    470 F.2d 1245
    , 1252–53 (D.C. Cir. 1972)). The BIA reasoned that
    
    18 U.S.C. § 3
     “criminalizes actions knowingly taken to
    ‘hinder or prevent (another’s) apprehension, trial or
    punishment.’” 
    Id.
    Hoang relied in part on another BIA en banc decision,
    Espinoza-Gonzales, issued two years after Batista-
    Hernandez. The BIA in Espinoza-Gonzales (in a decision
    written by Board Member Grant) held that the federal crime
    of misprision of a felony under 
    18 U.S.C. § 4
     is not “an
    offense relating to obstruction of justice.” 22 I. & N. Dec. at
    892–95.4 The Hoang majority analyzed the BIA’s approach
    to the differences between 
    18 U.S.C. § 3
     and 
    18 U.S.C. § 4
     as
    follows:
    Espinoza-Gonzalez distinguished misprision
    of a felony from accessory after the fact on
    the grounds that the latter both “references the
    specific purpose for which” the act is done,
    22 I. & N. Dec. at 894, and requires “as an
    element either active interference with
    proceedings of a tribunal or investigation, or
    action or threat of action against those who
    4
    
    18 U.S.C. § 4
     (“Misprision of felony”) provides:
    Whoever, 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.
    VALENZUELA GALLARDO V. LYNCH                     41
    would cooperate in the process of justice.” 
    Id. at 895
    . The BIA stated that “concealment of
    a crime [as in 
    18 U.S.C. § 4
    ] is qualitatively
    different from an affirmative action to hinder
    or prevent another’s apprehension, trial, or
    punishment [as in 
    18 U.S.C. § 3
    ]. It is a
    lesser offense to conceal a crime where there
    is no investigation or proceeding, or even an
    intent to hinder the process of justice. . . .” 
    Id. at 895
     (emphasis added). Taken as a whole,
    Espinoza-Gonzalez does not suggest that the
    BIA considered accessory after the fact to be
    an offense relating to obstruction of justice
    even though it does not require the defendant
    to interfere with an ongoing proceeding or
    investigation. The language used indicates
    that the BIA now concludes [in Espinoza-
    Gonzalez] that accessory after the fact is an
    obstruction of justice crime when it interferes
    with an ongoing proceeding or investigation.
    
    641 F.3d at 1164
    .
    A year later, the BIA in Valenzuela Gallardo specifically
    responded to Hoang (in a decision also written by Board
    Member Grant, the author of Espinoza-Gonzalez) by
    explicitly reaffirming Batista-Hernandez and clarifying
    Espinoza-Gonzales. See Valenzuela Gallardo, 25 I. & N.
    Dec. at 844. The BIA “respectfully invoke[d] the authority
    in Brand X to clarify [its] prior precedents on the scope of the
    phrase ‘relating to obstruction of justice.’” Id. at 840. In
    explaining Espinoza-Gonzales, Valenzuela Gallardo
    reiterated that the key distinction between 
    18 U.S.C. § 3
     and
    
    18 U.S.C. § 4
     is that § 3 “references the specific purposes for
    42          VALENZUELA GALLARDO V. LYNCH
    the concealment, which are hindering or preventing the
    ‘apprehension, trial or punishment’ of the principal offender.”
    Id. at 841 (quoting 
    18 U.S.C. § 3
    ). In contrast, “nothing in
    § 4 . . . references the specific purpose[.]” Id. (quoting
    Espinoza-Gonzalez, 22 I. & N. Dec. at 894). Valenzuela
    Gallardo reasoned:
    [W]e supported this distinction by pointing
    out that “concealment of a crime is
    qualitatively different from an affirmative
    action to hinder or prevent another’s
    apprehension, trial or punishment.”
    [Espinoza-Gonzalez, 22 I. & N. Dec.] at 895.
    We concluded that misprision does not
    constitute “obstruction of justice” because “it
    lacks the critical element of an affirmative and
    intentional attempt, motivated by a specific
    intent, to interfere with the process of justice.”
    Id. at 896. This element – the affirmative and
    intentional attempt, with specific intent, to
    interfere with the process of justice –
    demarcates the category of crimes constituting
    obstruction of justice. While many crimes
    fitting this definition will involve interference
    with an ongoing criminal investigation or
    trial, id. at 892–93, we now clarify that the
    existence of such proceedings is not an
    essential element of “an offense relating to
    obstruction of justice.”
    25 I. & N. Dec. at 841.
    In other words, the BIA disagrees with the Hoang
    majority’s conclusion that “[t]aken as a whole, Espinoza-
    VALENZUELA GALLARDO V. LYNCH                      43
    Gonzalez does not suggest that the BIA considered accessory
    after the fact to be an offense relating to obstruction of justice
    even though it does not require the defendant to interfere with
    an ongoing proceeding or investigation.” Hoang, 
    641 F.3d at 1164
    . It disagrees with the Hoang majority’s interpretation
    that “the BIA now concludes [in Espinoza-Gonzalez] that
    accessory after the fact is an obstruction of justice crime
    when it interferes with an ongoing proceeding or
    investigation.” 
    Id.
     Espinoza-Gonzales never required a
    crime of conviction to have as an element only “active
    interference with proceedings of a tribunal;” it always
    required “either active interference with proceedings of a
    tribunal or investigation, or action or threat of action against
    those who would cooperate in the process of justice.” 22 I. &
    N. Dec. at 893 (emphasis added).
    The purpose of Valenzuela Gallardo was not to announce
    a new comprehensive BIA interpretation; it was simply to
    reaffirm and clarify its precedent that – despite Hoang – a
    pending or ongoing investigation or proceeding is not a
    necessary element of a crime “relating to obstruction of
    justice.” 25 I. & N. Dec. at 844. It must be read together
    with both Batista-Hernandez and Espinoza-Gonzalez as
    establishing the BIA’s construction of “relating to obstruction
    of justice.”
    Applying the categorical approach to California Penal
    Code § 32, Valenzuela Gallardo then reasoned that:
    The provisions of this statute are closely
    analogous, if not functionally identical, to
    those in 
    18 U.S.C. § 3
    . Critically, both
    statutes include the element of an affirmative
    and intentional attempt, motivated by a
    44            VALENZUELA GALLARDO V. LYNCH
    specific intent, to interfere with the process of
    justice. See 
    18 U.S.C. § 3
     (requiring that the
    offender act “in order to hinder or prevent
    [the principal’s] apprehension, trial or
    punishment”) (emphasis added); 
    Cal. Penal Code § 32
     (West 2012) (requiring that the
    offender act “with the intent that [the]
    principal may avoid or escape from arrest,
    trial, conviction or punishment”) (emphasis
    added)[.]
    25 I. & N. Dec. at 841–42. The BIA thus gives meaning to
    the term “process of justice” by referring to statutes and
    obstructive acts even without a pending proceeding or
    ongoing investigation.5 And it based its decision on the same
    key factor that it has applied since at least 1999 in Espinoza-
    Gonzalez – whether a crime has “the critical element of an
    affirmative and intentional attempt, motivated by specific
    intent, to interfere with the process of justice.” In this
    fundamental aspect, the decision was hardly a new
    interpretation.
    Valenzuela Gallardo also considered that
    § 1101(a)(43)(S) requires only an offense to be “relating to”
    obstruction of justice, indicating that a broader reading is
    proper. 25 I. & N. Dec. at 843. And it recognized that the
    Third Circuit in Denis v. Attorney General, 
    633 F.3d 201
    , 209
    (3d Cir. 2011), considered the phrase “relating to obstruction
    5
    Furthermore, “hindering or preventing” a principal’s “apprehension,
    trial, or punishment” satisfies a “materiality” requirement that may be
    necessary to satisfy vagueness concerns with some obstruction crimes.
    See, e.g., United States v. Bonds, 
    784 F.3d 582
    , 585 (9th Cir. 2015) (en
    banc) (Kozinski, J., concurring).
    VALENZUELA GALLARDO V. LYNCH                            45
    of justice” to be unambiguous such that a conviction for
    accessory after the fact in the Third Circuit would necessarily
    qualify as an obstruction offense under § 1101(a)(43)(S).
    Reasoning (properly) that “[a]n important purpose of [BIA]
    precedent is the establishment of a uniform interpretation of
    law in cases before the Immigration Judges and the [BIA],”
    id. at 844 (quoting Matter of U. Singh, 
    25 I. & N. Dec. 670
    ,
    672 (B.I.A. 2012)), it concluded that “accessory after the fact
    offenses necessarily relate to obstruction of justice”
    irrespective of the existence of an ongoing criminal
    investigation or proceeding. Id.6
    6
    After Valenzuela Gallardo was issued in 2012, the Eighth Circuit
    similarly interpreted Espinoza-Gonzales to mean that a Nebraska witness-
    tampering statute (
    Neb. Rev. Stat. § 28-919
    (1)) is a crime “relating to
    obstruction of justice” for purposes of § 1101(a)(43)(S). See Armenta-
    Lagunas v. Holder, 
    724 F.3d 1019
    , 1022–24 (8th Cir. 2013). Although
    Armenta-Lagunas did not specifically address vagueness or whether a
    pending proceeding is required, it found nothing uncertain about the BIA’s
    formulation:
    [T]he offenses entitled “Obstruction of Justice” all
    required “the critical element of an affirmative and
    intentional attempt, motivated by a specific intent, to
    interfere with the process of justice.” [Espinoza-
    Gonzales, 22 I. & N. Dec.] at 894. “In other words . . .
    it must include as elements both (1) the actus reus of an
    ‘active interference with proceedings of a tribunal or
    investigation, or action or threat of action against those
    who would cooperate in the process of justice,’ and
    (2) the mens rea of a ‘specific intent to interfere with
    the process of justice.’” Higgins v. Holder, 
    677 F.3d 97
    ,
    102 (2d Cir. 2012) (quoting Espinoza-Gonzalez, 22 I. &
    N. Dec. at 893).
    724 F.3d at 1022.
    46             VALENZUELA GALLARDO V. LYNCH
    In short, this case involves a straightforward application
    of Chevron. The court should defer to the BIA’s reasonable,
    permissible, and plausible interpretation of § 1101(a)(43)(S).
    III.     The use of the constitutional avoidance doctrine in
    this case undermines Congressional intent
    Moreover, in the context now before us – where it is
    undisputed that the statutory language is ambiguous – the
    constitutional avoidance doctrine is an inappropriate
    framework to disregard the BIA’s interpretation. Certainly,
    if the BIA’s definition is unconstitutional, then we have the
    power to strike it or make such a declaration. But Morales-
    Izquierdo, an en banc opinion of this court, in no uncertain
    terms reasons that “the constitutional avoidance doctrine . . .
    plays no role in the second Chevron inquiry.” 
    486 F.3d at 493
    . That is,
    Similarly, the Second Circuit in Higgins concluded that a Connecticut
    witness-tampering statute (Conn. Gen. Stat. § 53a-151) is a crime “relating
    to obstruction of justice.” See 
    677 F.3d at
    105–06 (citing Espinoza-
    Gonzales). And in United States v. Gamboa-Garcia, 
    620 F.3d 546
     (5th
    Cir. 2010), the Fifth Circuit held the same for an Idaho accessory statute
    (
    Idaho Code § 18-205
    ). See id. at 550.
    Notably, the witness-tampering statutes analyzed in Armenta-Lagunas
    and Higgins both require a perpetrator to “believ[e] that an official
    proceeding” “is pending or about to be instituted.” Armenta-Lagunas,
    724 F.3d at 1023 (emphasis added); Higgins, 
    677 F.3d at 104
     (same).
    Likewise, 
    Idaho Code § 18-205
    , analyzed in Gamboa-Garcia, does not
    refer to a pending proceeding. The majority Opinion’s approach is thus
    inconsistent with the Second (Higgins), Fifth (Gamboa-Garcia) and
    Eighth Circuits (Armenta-Lagunas) – creating or perpetuating a circuit
    split.
    VALENZUELA GALLARDO V. LYNCH                            47
    we are not deciding between two plausible
    statutory constructions; we are evaluating an
    agency’s interpretation of a statute under
    Chevron. At step two of this inquiry, our
    function is “not simply [to] impose [our] own
    construction on the statute, as would be
    necessary in the absence of an administrative
    interpretation. Rather, . . . the question for the
    court is whether the agency’s answer is based
    on a permissible construction of the statute.”
    When Congress has explicitly or implicitly
    left a gap for an agency to fill, and the agency
    has filled it, we have no authority to re-
    construe the statute, even to avoid potential
    constitutional problems; we can only decide
    whether the agency’s interpretation reflects a
    plausible reading of the statutory text.
    
    Id.
     at 492–93 (quoting Chevron, 
    467 U.S. at 843
    ) (emphasis
    added) (brackets and ellipses in original).7
    Rather than giving deference to the BIA’s permissible
    formulation, the majority Opinion (avoiding Morales-
    Izquierdo’s logic) relies on authority indicating that
    constitutional avoidance can apply at Chevron step one. See,
    e.g., Morales-Izquierdo, 
    486 F.3d at 504
     (“The avoidance
    canon . . . is properly applied at step one of the Chevron
    7
    See also Garcia-Villeda v. Mukasey, 
    531 F.3d 141
    , 149 (2d Cir. 2008)
    (“[T]he doctrine is unavailing to petitioner, because, as the Ninth Circuit
    held, once an ambiguous statute has been interpreted by the agency in
    charge of its implementation, we lack the ‘authority to re-construe the
    statute, even to avoid potential constitutional problems.’”) (quoting
    Morales-Izquierdo, 
    486 F.3d at 493
    ).
    48          VALENZUELA GALLARDO V. LYNCH
    analysis. While . . . the avoidance canon cannot be used to
    render an agency’s interpretation ‘unreasonable’ at Chevron
    step two, the canon is unquestionably a ‘traditional tool of
    statutory interpretation’ that may and should be used to
    determine whether Congress intended to preclude the
    agency’s chosen interpretation.”) (citations omitted)
    (Thomas, C.J., dissenting); but cf. Olmos v. Holder, 
    780 F.3d 1313
    , 1321 (10th Cir. 2015) (“[T]he canon on constitutional
    avoidance does not bear on our inquiry at step one.”).
    That is, although the majority Opinion acknowledges that
    the term “relating to obstruction of justice” is ambiguous, it
    applies the canon of constitutional avoidance because
    Congress could not have intended an agency construction that
    approaches a constitutional boundary without some indication
    allowing such a construction. But this reasoning utterly
    disregards the term “relating to,” which indicates a broad
    interpretation – meaning Congress intended to include not
    only crimes that actually constitute “obstruction of justice,”
    but also crimes that are “relating to” such crimes. See, e.g.,
    Rodriguez-Valencia v. Holder, 
    652 F.3d 1157
    , 1159 (9th Cir.
    2011) (“When interpreting the INA, we construe the ‘relating
    to’ language broadly.”) (quoting Luu-Le v. I.N.S., 
    224 F.3d 911
    , 915 (9th Cir. 2000) (some quotation marks omitted)).
    For example, in analyzing an aggravated felony statute,
    
    8 U.S.C. § 1101
    (a)(43)(R) (including as an aggravated felony
    an “offense relating to commercial bribery, counterfeiting,
    forgery, or trafficking in vehicles . . . for which the term of
    imprisonment is at least one year”), Albillo-Figuero v. I.N.S.,
    
    221 F.3d 1070
     (9th Cir. 2000), held that the clause “relating
    to” “necessarily covers a range of activities beyond those of
    counterfeiting or forgery itself.” 
    Id. at 1073
    . As Kamagate
    v. Ashcroft, 
    385 F.3d 144
     (2d Cir. 2004), reasoned, “the
    VALENZUELA GALLARDO V. LYNCH                              49
    phrase ‘relating to’ . . . is [often] used [in the INA] . . . to
    define aggravated felonies by reference to the general subject
    of the offense of conviction, suggesting Congress’s intent to
    reach more broadly than any single statute.” 
    Id.
     at 154 (citing
    
    8 U.S.C. §§ 1101
    (a)(43)(K)(i), (Q), (S), & (T)).8
    Thus, by using the term “relating to” in § 1101(a)(43)(S),
    Congress intended to reach a wide spectrum of obstruction
    crimes, even those that may reach near to the limits of
    congressional authority. It surely meant to include more than
    crimes constituting obstruction of justice, not just some of
    them.
    The exception “to hesitate before concluding that
    Congress has intended such an implicit delegation,” should be
    reserved for major or “extraordinary cases.” See Brown &
    Williamson, 
    529 U.S. at 159
     (“In extraordinary cases,
    however, there may be reason to hesitate before concluding
    that Congress has intended such an implicit delegation.”)
    (emphasis added) (citing Stephen Breyer, Judicial Review of
    Questions of Law and Policy, 
    38 Admin. L. Rev. 363
    , 370
    (1986)). And, although the issues we face regarding the
    meaning of “relating to obstruction of justice” have proven to
    be challenging, this is not an extraordinary case. Compare
    8
    Contrary to the majority’s view, Mellouli v. Lynch, 
    135 S. Ct. 1980
    ,
    1990 (2015) (cautioning that courts may not extend “relating to” “to the
    furthest stretch of [its] indeterminacy” where language and historical
    context “tug in favor of a narrower reading”) does not change this
    reasoning. See United States v. Sullivan, 
    797 F.3d 623
    , 639 (9th Cir.
    2015) (“[W]e interpret the phrase ‘relating to’ broadly . . . unless the text
    and history of the statute require a narrower construction.”) (some
    editorial marks and citation omitted) (discussing Mellouli), petition for
    cert. filed (U.S. Jan. 28, 2016) (No. 15-7875). Nothing here “tugs in favor
    of a narrower reading” as was analyzed in Mellouli.
    50          VALENZUELA GALLARDO V. LYNCH
    King, 
    135 S. Ct. at 2489
     (upholding the Patient Protection
    and Affordable Care Act despite statutory ambiguity because
    “[t]his is one of those [extraordinary] cases”) (referring to
    Brown & Williamson, 
    529 U.S. at 159
    ). Because this is not
    such a case, the BIA is owed deference. And applying the
    constitutional avoidance doctrine in this instance – where the
    constitutional questions are not “serious” (as explained to
    follow) – invites courts to apply an exception whenever there
    is statutory ambiguity. Cf. Liu v. Waters, 
    55 F.3d 421
    , 426
    (9th Cir. 1995) (“[W]e must not allow [an] exception for
    constitutional questions to swallow the rule.”).
    The majority Opinion correctly states that we must ask
    whether Congress intended to permit the agency
    interpretation, and the doctrine of constitutional avoidance
    can sometimes aid in this task. But by reading the term
    “relating to” out of the statute, the majority Opinion ignores
    true Congressional intent. That is, because Congress’ use of
    the term “relating to” demonstrates intent to broaden the
    scope of covered obstruction-related crimes, the doctrine
    should not be employed to narrow the scope of covered
    crimes. In short, the majority Opinion’s use of the doctrine
    as applied here does not further Congressional intent but
    instead undermines it.
    IV.    The BIA’s construction does not present “serious”
    or “grave” constitutional concerns
    More to the point, even examining the BIA’s construction
    at Chevron step one, the constitutional avoidance doctrine
    only applies to truly “serious” constitutional questions. See
    Edward J. DeBartolo Corp. v. Florida Gulf Coast Bldg. and
    Constr. Trades Council, 
    485 U.S. 568
    , 577 (1988); Williams,
    
    115 F.3d at 662
     (“Only if the agency’s proffered
    VALENZUELA GALLARDO V. LYNCH                    51
    interpretation raises serious constitutional concerns may a
    court refuse to defer under Chevron.”). They must be
    “grave.” Rust v. Sullivan, 
    500 U.S. 173
    , 191 (1991);
    Williams, 
    115 F.3d at 663
     (“[C]onstitutional narrowing
    should displace Chevron only when the constitutional
    problems are truly ‘grave’ . . . because all possible
    interpretations raise constitutional problems.”). “[T]he
    ‘constitutional doubt’ doctrine does not apply mechanically
    whenever there arises a significant constitutional question the
    answer to which is not obvious.” Almendarez-Torres v.
    United States, 
    523 U.S. 224
    , 239 (1998). That is, “we do not
    abandon Chevron deference at the mere mention of a possible
    constitutional problem[.]” Kempthorne, 
    512 F.3d at 711
    .
    “An agency’s interpretation may be permissible even if it
    would create constitutional issues.” Olmos, 780 F.3d at
    1322–23 (citing Morales-Izquierdo, 
    486 F.3d at 493
    ).
    Here, the BIA’s interpretation in Valenzuela Gallardo
    does not approach the void-for-vagueness line. It is true that
    obstruction of justice crimes punishing acts intended to
    impede “the due administration of justice,” such as the
    omnibus clause in 
    18 U.S.C. § 1503
    (a), have a potentially
    “vast” coverage. Bonds, 784 F.3d at 583 (Kozinski, J.,
    concurring). But federal obstruction statutes are not
    unconstitutionally vague where they include a mens rea of
    “corruptly persuade” or “corruptly endeavor.” See, e.g.,
    United States v. Jeter, 
    775 F.2d 670
    , 679 (6th Cir. 1985)
    (rejecting that 
    18 U.S.C. § 1503
     is unconstitutionally
    overbroad or vague given “its explicit mens rea requirement
    that a person must ‘corruptly’ endeavor to interfere with the
    due administration of justice. Thus, one must impede the due
    administration of justice with the general intent of knowledge
    as well as the specific intent of purpose to obstruct.”)
    (citations omitted); United States v. Shotts, 
    145 F.3d 1289
    ,
    52            VALENZUELA GALLARDO V. LYNCH
    1300 (11th Cir. 1998) (rejecting vagueness challenge to
    
    18 U.S.C. § 1512
    (b), reasoning in part that ‘“corrupt’ is a
    scienter requirement which provides adequate notice of what
    conduct is proscribed”) (citing United States v. Thompson,
    
    76 F.3d 442
    , 452 (2d Cir. 1996)).
    Under Ninth Circuit law, “corruptly” in this context
    means that the obstructive conduct “must be done with the
    purpose of obstructing justice.” United States v. Rasheed,
    
    663 F.2d 843
    , 852 (9th Cir. 1981); United States v. Laurins,
    
    857 F.2d 529
    , 536–37 (9th Cir. 1988).9 And this definition of
    “corruptly” is the functional equivalent to the BIA’s language
    at issue here (“the affirmative and intentional attempt, with
    specific intent, to interfere with the process of justice,
    irrespective of the existence of an ongoing criminal
    investigation or proceeding”). That is, the BIA requires a
    “corrupt” mens rea in its construction.
    The majority Opinion reasons that without a nexus to
    pending or ongoing proceedings – as the Ninth Circuit in
    Hoang had interpreted Espinoza-Gonzales – the meaning of
    “the process of justice” is vague (or approaches that line).
    And it is true that many, if not all, obstruction crimes require
    some connection between the obstructive act and a
    “proceeding.” See Arthur Andersen LLP v. United States,
    
    544 U.S. 696
    , 707–08 (2005) (indicating that a nexus to a
    foreseeable or contemplated proceeding might suffice under
    
    18 U.S.C. § 1512
    ). But in my view, because a pending
    9
    Cf. 
    18 U.S.C. § 1515
    (b) (“As used in section 1505, the term
    “corruptly” means acting with an improper purpose, personally or by
    influencing another, including making a false or misleading statement, or
    withholding, concealing, altering, or destroying a document or other
    information.”).
    VALENZUELA GALLARDO V. LYNCH                   53
    proceeding does not create the necessary connection, the
    BIA’s definition is not missing the required nexus. If a
    person specifically interferes with an ongoing investigation,
    then the requisite specific purpose of an obstructive act is
    obvious. But obstruction does not require the investigation
    or proceeding to be pending. “Pending” is sufficient, but not
    necessary. And its absence does not render the definition
    unconstitutionally vague.
    Rather, what is necessary is a connection to some
    contemplated “process of justice” that encompasses an “evil
    intent to obstruct.” United States v. Aguilar, 
    515 U.S. 593
    ,
    599 (1995) (“[A] person lacking knowledge of a pending
    proceeding necessarily lacked the evil intent to obstruct.”)
    (citing Pettibone v. United States, 
    148 U.S. 197
    , 207 (1893)).
    This “evil intent” is adequately articulated by the BIA as “an
    affirmative and intentional attempt, with specific intent, to
    interfere with the process of justice.” Moreover, Valenzuela
    Gallardo (as well as Batista-Hernandez and Espinoza-
    Gonzalez) describes or refers to “the process of justice” as
    including arrest, apprehension, conviction, or punishment.
    See 25 I. & N. Dec. at 841–42. Valenzuela Gallardo also
    refers to specific federal obstruction crimes, as detailed to
    follow, that do not require proceedings to be pending, and
    that also give further meaning to “the process of justice.”
    A. Crimes Under 
    18 U.S.C. § 1512
    Prime examples of federal obstruction crimes that do not
    require “pending proceedings” are witness-tampering crimes
    set forth in 
    18 U.S.C. § 1512
     such as:
    • 
    18 U.S.C. § 1512
    (b) (“Whoever knowingly
    uses intimidation, threatens, or corruptly
    54          VALENZUELA GALLARDO V. LYNCH
    persuades another person, or attempts to do
    so, or engages in misleading conduct toward
    another person, with intent to – (1) influence,
    delay, or prevent the testimony of any person
    in an official proceeding”); and
    • 
    18 U.S.C. § 1512
    (c) (“Whoever corruptly –
    (1) alters, destroys, mutilates, or conceals a
    record, document, or other object, or attempts
    to do so, with the intent to impair the object’s
    integrity or availability for use in an official
    proceeding; or (2) otherwise obstructs,
    influences, or impedes any official
    proceeding, or attempts to do so, shall be
    fined under this title or imprisoned not more
    than 20 years, or both.”).
    Although these crimes require some connection to an
    “official proceeding,” they do not require it to be pending.
    See 
    18 U.S.C. § 1512
    (f)(1) (“For the purposes of this section
    . . . an official proceeding need not be pending or about to be
    instituted at the time of the offense.”). Congress adopted this
    language to encompass a perpetrator’s actions even before an
    investigation has begun. Legislative history explains:
    [Section 1512(f)(1)] obviates the requirement
    that there be an official proceeding in progress
    or pending. The Committee felt that this
    increases the scope of the section by
    expanding the galaxy of witnesses and victims
    the protections of its language is meant to
    embrace.        Intimidation offenses are
    particularly insidious and do violence to
    traditional notions of justice because no one
    VALENZUELA GALLARDO V. LYNCH                    55
    can be convicted of a crime which is not
    reported. Subsection [(f)(1)], among other
    things, specifically reaches intimidation
    offenses before a crime is reported to the
    appropriate authorities.
    Judiciary Comm., 97th Cong., Victim and Witness Protection
    Act of 1982, S. Rep. No. 97-532, at 19 (1982), reprinted in
    1982 U.S.C.C.A.N. 3 (emphasis added).
    That is, although the government must still connect the
    obstructive act to an official proceeding under § 1512(b)(1),
    see Arthur Andersen, 
    544 U.S. at
    707–08, the nexus does not
    have to be to an ongoing proceeding. Rather, it requires
    proof under § 1512(b)(1) of a foreseeable or contemplated
    proceeding. See id. (“It is, however, one thing to say that a
    proceeding ‘need not be pending or about to be instituted at
    the time of the offense,’ and quite another to say a proceeding
    need not even be foreseen. A ‘knowingly . . . corrup[t]
    persuade[r]’ cannot be someone who persuades others to
    shred documents under a document retention policy when he
    does not have in contemplation any particular official
    proceeding in which those documents might be material.”);
    see also United States v. Friske, 
    640 F.3d 1288
    , 1292 n.5
    (11th Cir. 2011) (“Consistent with Aguilar’s nexus
    requirement, the government must prove [under § 1512(c)(2)]
    that the defendant knew of or foresaw an official proceeding,
    and knew that his actions were likely to affect it.”).
    Other obstruction of justice crimes in § 1512 do not even
    require an “official proceeding:”
    •    
    18 U.S.C. § 1512
    (d)(2) (“Whoever
    intentionally harasses another person and
    56          VALENZUELA GALLARDO V. LYNCH
    thereby hinders, delays, prevents, or dissuades
    any person from . . . reporting to a law
    enforcement officer or judge of the United
    States the commission or possible commission
    of a Federal offense . . . . or attempts to do so,
    shall be fined under this title or imprisoned
    not more than 3 years, or both.”); and
    •     
    18 U.S.C. § 1512
    (b)(3) (“Whoever
    knowingly uses intimidation, threatens, or
    corruptly persuades another person, or
    attempts to do so, or engages in misleading
    conduct toward another person, with intent to
    . . . hinder, delay, or prevent the
    communication to a law enforcement officer
    or judge of the United States of information
    relating to the commission or possible
    commission of a Federal offense . . . shall be
    fined under this title or imprisoned not more
    than 20 years, or both.”).
    These sections “make[] no mention of ‘an official
    proceeding’ and do[] not require that a defendant’s
    misleading conduct relate in any way either to an ‘official
    proceeding’ or even to a particular ongoing investigation.”
    United States v. Ronda, 
    455 F.3d 1273
    , 1288 (11th Cir.
    2006). “[Section] 1512(b)(3) requires only that a defendant
    intended to hinder, delay, or prevent communication to any
    ‘law enforcement officer or judge of the United States’ [and
    thus] requires only ‘the possible existence of a federal crime
    and a defendant’s intention to thwart an inquiry into that
    crime.’” 
    Id.
     (quoting United States v. Veal, 
    153 F.3d 1233
    ,
    1250 (11th Cir. 1998)). See also, e.g., United States v.
    Guadalupe, 
    402 F.3d 409
    , 411 (3d Cir. 2005) (“[P]roving a
    VALENZUELA GALLARDO V. LYNCH                     57
    violation of 
    18 U.S.C. § 1512
    (b)(3) does not depend on the
    existence or imminency of a federal investigation but rather
    on the possible existence of a federal crime and a defendant’s
    intention to thwart an inquiry into that crime by officials who
    happen to be federal.”) (emphases added); United States v.
    Baldyga, 
    233 F.3d 674
    , 680 (1st Cir. 2000) (noting that
    defendant’s conduct violated § 1512(b)(3) where he hindered
    government cooperator’s “communication with authorities”
    and where “the possibility existed that such communication
    would eventually occur with federal officials”) (emphasis
    added).
    These types of obstruction crimes, while not requiring a
    nexus to a pending proceeding, can fairly and reasonably be
    said to require a specific intent to interfere with “the process
    of justice.” See, e.g., United States v. Byrne, 
    435 F.3d 16
    , 24
    (1st Cir. 2006) (“[S]ubsection (b)(3) ‘does not connect the
    federal interest with an ongoing or imminent judicial
    proceeding,’ but rather ‘speaks more broadly’ to ‘the
    character of the affected activity, the transmission of
    information to federal law enforcement agents[.]’”) (quoting
    Veal, 
    153 F.3d at
    1250–51). See also United States v.
    Phillips, 
    583 F.3d 1261
    , 1264 (10th Cir. 2009) (“[I]n terms of
    the Aguilar nexus requirement, a conviction is proper [under
    § 1512(c)] if interference with the official proceeding is the
    ‘natural and probable effect’ of the defendant’s conduct.”);
    Friske, 
    640 F.3d at 1292
     (“Aguilar relied on the principle that
    ‘a person lacking knowledge of a pending proceeding
    necessarily lack[s] the evil intent to obstruct.’”) (quoting
    Aguilar, 
    515 U.S. at 599
    ).

    B. Another example – 
    18 U.S.C. § 1519
    Another example is destroying documents intending to
    obstruct a federal investigation under 
    18 U.S.C. § 1519
    .
    This obstruction crime has a very specific mens rea. It
    criminalizes the knowing alteration, destruction, mutilation,
    etc., of records, documents, or “tangible objects,” intending
    to obstruct the investigation or proper administration of
    matters within federal jurisdiction.10 Section 1519 “covers
    conduct intended to impede any federal investigation or
    proceeding including one not even on the verge of
    commencement.” Yates v. United States, 
    135 S. Ct. 1074
    ,
    1087 (2015) (emphasis added). See also United States v.
    Gray, 
    642 F.3d 371
    , 379 (2d Cir. 2011) (“[Section] 1519 does
    not require the existence or likelihood of a federal
    investigation.”); United States v. Moyer, 
    674 F.3d 192
    , 210
    (3d Cir. 2012) (“[The government] was not required to prove
    that [Defendant] intended to obstruct or impede a specific
    federal investigation.”). “To ensure that the statute is applied
    ‘broadly,’ criminal liability ‘also extends to acts done in
    contemplation of such federal matters, so that the timing of
    the act in relation to the beginning of the matter or
    10
    Section § 1519, entitled “Destruction, alteration, or falsification of
    records in Federal investigations and bankruptcy,” provides:
    Whoever knowingly alters, destroys, mutilates,
    conceals, covers up, falsifies, or makes a false entry in
    any record, document, or tangible object with the intent
    to impede, obstruct, or influence the investigation or
    proper administration of any matter within the
    jurisdiction of any department or agency of the United
    States or any case filed under title 11, or in relation to
    or contemplation of any such matter or case, shall be
    fined under this title, imprisoned not more than 20
    years, or both.
    VALENZUELA GALLARDO V. LYNCH                             59
    investigation is also not a bar to prosecution.’” Moyer,
    
    674 F.3d at 210
     (quoting S. Rep. No. 107-146, at 13 (2002));
    see also United States v. Yielding, 
    657 F.3d 688
    , 711 (8th Cir.
    2011) (similar reasoning).11
    Section 1519 is not vague. “Section 1519’s scienter
    requirement . . . eliminates any concerns regarding statutory
    vagueness.” Moyer, 
    674 F.3d at 211
    . Specifically,
    “[b]ecause a defendant will be convicted for violating § 1519
    ‘only for an act knowingly done with the purpose of doing
    that which the statute prohibits, the accused cannot be said to
    suffer from lack of warning or knowledge that the act which
    he does is a violation of law.’” Id. at 212 (quoting Screws v.
    United States, 
    325 U.S. 91
    , 102 (1945)). “Here, by the
    express language of [§ 1519], no liability will be imposed for
    knowingly falsifying documents without an ‘intent to impede,
    obstruct, or influence a matter.’” Id.
    11
    Indeed, several Circuits have held that no “nexus” (as that term is used
    in Aguilar and Arthur Andersen) is required at all under § 1519. See
    Yielding, 
    657 F.3d at 712
     (“We conclude that the ‘nexus’ requirement
    urged by Yielding – that the government must show the accused knew his
    actions were likely to affect a federal matter – does not apply to a
    prosecution for the knowing falsification of documents under § 1519. The
    text of § 1519 requires only proof that the accused knowingly committed
    one of several acts, including falsification of a document, and did so ‘with
    the intent to impede, obstruct, or influence the investigation or proper
    administration’ of a federal matter.”); Gray, 
    642 F.3d at 378
     (“In view of
    the statute’s plain language, which is fully consistent with the legislative
    history, we decline to read any such nexus requirement into the text of
    § 1519.”); Moyer, 
    674 F.3d at 209
     (“We conclude that proof of such a
    nexus is not required.”). Nevertheless, cases speak in terms of
    “foreseeable” or “contemplated” proceedings. See Yielding, 
    657 F.3d at 811
    ; Moyer, 
    674 F.3d at 210
    .
    60           VALENZUELA GALLARDO V. LYNCH
    In rejecting a vagueness challenge to § 1519, Yielding
    reasoned that “the statute does not impose liability for
    ‘knowingly . . . destroy[ing] . . . any . . . document . . . in . . .
    contemplation of any [federal] matter,’ without an intent to
    impede, obstruct, or influence a matter. If it did, then the
    statute would forbid innocent conduct such as routine
    destruction of documents that a person consciously and in
    good faith determines are irrelevant to a foreseeable federal
    matter.” 
    657 F.3d at 711
     (editorial marks in original).
    Yielding concluded: “[t]he plain language of the statute
    forbids the knowing falsification of a document with the
    intent to impede, obstruct, or influence the investigation or
    proper administration of a federal matter, even if that matter
    is not pending at the time of the obstructive act.” 
    Id. at 715
    .
    See also United States v. Kernell, 
    667 F.3d 746
    , 753–56 (6th
    Cir. 2012) (rejecting vagueness challenge to § 1519); United
    States v. Hunt, 
    526 F.3d 739
    , 743 (11th Cir. 2008) (same).
    Similarly, Valenzuela Gallardo’s formulation –
    affirmative and intentional attempt, motivated by a specific
    intent, to interfere with the process of justice, irrespective of
    the existence of an ongoing criminal investigation or
    proceeding – encompasses acts done with the purpose of
    impeding or obstructing justice. See, e.g., Rasheed, 
    663 F.2d at 852
    . That is, like § 1519’s requirement to intend to
    influence “the investigation or proper administration of any
    [federal] matter,” the BIA’s formulation requires a specific
    intent to interfere with the process of justice “irrespective of
    the existence of an ongoing criminal investigation or
    proceeding.”

    C. The majority Opinion’s other criticisms do not
    help its vagueness analysis
    In discussing vagueness, the majority Opinion also faults
    the BIA for providing little instruction as to the requisite
    actus reus, with no indication of what conduct must be
    interfered with. But the BIA requires “affirmative action
    knowingly undertaken,” 25 I. & N. Dec. at 840 (quoting
    Espinoza-Gonzalez, 22 I. & N. Dec. at 894) (emphasis added)
    – that is, an act – and Espinoza-Gonzales further defines the
    actus reus as “either active interference with proceedings of
    a tribunal or investigation, or action or threat of action against
    those who would cooperate in the process of justice.” 22 I. &
    N. at 893 (emphasis added). As the Eighth Circuit reasons,
    the BIA has not eliminated an actus reus. See Armenta-
    Lagunas, 724 F.3d at 1024 (“To satisfy the actus reus
    element, the statute of conviction simply must require an
    active interference with proceedings of a tribunal or
    investigation, or action or threat of action against those who
    would cooperate in the process of justice.”).
    Applying the categorical approach, California Penal Code
    § 32 includes as elements specific instances of conduct that
    interfere with the process of justice (“harbors, conceals or
    aids a principal . . . with the intent that said principal may
    avoid or escape from arrest, trial, conviction, or
    punishment[.]”). Petitioner’s California conviction was for
    a crime that necessarily requires “an affirmative and
    intentional attempt, motivated by a specific intent, to interfere
    with the process of justice, irrespective of the existence of an
    ongoing criminal investigation or proceeding.”
    And the majority Opinion’s citation to Johnson v. United
    States, 
    135 S. Ct. 2551
     (2015), does not support its
    62             VALENZUELA GALLARDO V. LYNCH
    conclusion that the BIA’s construction raises grave doubts as
    to vagueness. Johnson concluded that the Armed Career
    Criminal Act’s (“ACCA”) “residual clause,” which defines a
    “violent felony” as “any crime punishable by imprisonment
    for a term exceeding one year . . . that . . . ‘otherwise involves
    conduct that presents a serious potential risk of physical
    injury to another,’” 
    18 U.S.C. § 924
    (e)(2)(B)(ii), is
    unconstitutionally vague. 135 S. Ct. at 2557. Unlike
    Johnson, for the reasons just stated, the BIA’s formulation
    provides objective standards (it does not eliminate a required
    nexus, and adequately explains a connection to “the process
    of justice), and requires analyzing statutory definitions – not
    “judge-imagined abstraction[s].” Johnson, 
    135 S. Ct. at 2558
    . Moreover, Johnson declared the residual clause vague
    not only because of its indeterminancy, but because of a long
    history by the Supreme Court and other courts of “repeated
    attempts and repeated failures to craft a principled and
    objective standard out of” its language. 
    Id.
     There was a
    “pervasive disagreement about the nature of the inquiry one
    is supposed to conduct and the kinds of factors one is
    supposed to consider” among lower courts. 
    Id. at 2560
    .
    Nothing like that is involved with the BIA’s formulation.
    Johnson addressed vagueness as to the specific language of
    the residual clause by applying settled principles12 – it
    provides no support for questioning, on vagueness grounds,
    the BIA’s construction of § 1101(a)(43)(S).
    12
    Johnson concluded that the ACCA’s residual clause is
    unconstitutional because of two flaws – uncertainty as to: 1) how to
    estimate the risk posed by a crime in an “ordinary case,” and 2) how much
    risk is required for a crime to qualify. 135 S. Ct. at 2557–58. And the
    residual clause contains a list of exemplar crimes, causing further
    confusion. Id. at 2558. But the residual clause’s flaws simply don’t exist
    with the BIA’s definition requiring a specific intent to interfere with the
    process of justice.

    V. If applicable, we should apply constitutional
    avoidance differently
    Finally, even if the constitutional avoidance doctrine
    should be applied to the situation before us, we should apply
    it differently than how the majority Opinion does. When
    presented with grave doubts as to the constitutionality of a
    regulatory interpretation, courts should read the interpretation
    narrowly in a readily-apparent way to avoid the constitutional
    issue. See, e.g., Williams, 
    115 F.3d at 666
    ; Stansell, 
    847 F.2d at 615
     (“Because a reasonable limiting construction can be
    placed on the challenged regulation, we hold that [it] is not
    substantially overbroad.”) (emphasis added); Meinhold v.
    United States Dep’t of Defense, 
    34 F.3d 1469
    , 1479 (9th Cir.
    1994) (“[T]he regulation under which Meinhold was
    processed need not be construed so broadly as to raise
    constitutional concerns. It can reasonably be construed to
    reach only [constitutional grounds].”); United States v.
    Bulacan, 
    156 F.3d 963
    , 974 (9th Cir. 1998) (similar); cf. Ma
    v. Ashcroft, 
    257 F.3d 1095
    , 1106 (9th Cir. 2001) (“In the
    immigration context, courts have often read limitations into
    statutes that appeared to confer broad power on immigration
    officials in order to avoid constitutional problems.”). Put
    differently, “our task is not to destroy the Act . . . but to
    construe it, if consistent with the will of Congress, so as to
    comport with constitutional limitations.” U.S. Civil Serv.
    Comm’n v. Nat’l Ass’n of Letter Carriers, AFL-CIO, 
    413 U.S. 548
    , 571 (1973).
    In Edward J. DeBartolo Corp., when faced with a
    National Labor Relations Board’s (“NLRB”) interpretation
    that presented serious First Amendment questions, neither the
    Eleventh Circuit nor the Supreme Court remanded the action
    to the NLRB to promulgate a different interpretation – the
    64          VALENZUELA GALLARDO V. LYNCH
    Eleventh Circuit construed it “as not prohibiting consumer
    publicity.” 
    485 U.S. at 574
    . Edward J. DeBartolo Corp.
    concluded, “as did the [Eleventh Circuit], that the section is
    open to a construction that obviates deciding whether a
    congressional prohibition of handbilling . . . would violate the
    First Amendment.” 
    Id. at 578
    .
    Likewise, in Williams, the Ninth Circuit did not instruct
    the district court to remand the interpretation to the agency to
    allow it to reconsider its interpretation in a manner that did
    not violate equal protection, or come close to that line.
    Rather, given an agency interpretation that presented grave
    constitutional questions, Williams then “interpret[ed] the
    Reindeer Act as not precluding non-natives in Alaska from
    owning and importing reindeer.” 
    115 F.3d at 666
    .
    And so, even if Valenzuela Gallardo raises serious
    constitutional questions about vagueness, rather than
    remanding to the BIA, we can give the definition a limiting
    construction and construe it to include the necessary nexus
    where such a construction is readily apparent. And
    Valenzuela Gallardo can certainly be properly construed to
    fully encompass crimes “relating to obstruction of justice.”
    The BIA meant to include crimes with an element of
    interfering with “the process of justice,” such as preventing
    or impeding a principal’s apprehension, trial, or punishment.
    Valenzuela Gallardo, 25 I. & N. Dec. at 841. Such a meaning
    is obvious from Valenzuela Gallardo, especially when read
    in conjunction with the BIA’s en banc decisions in Batista
    Hernandez and Espinoza-Gonzalez, both of which Valenzuela
    VALENZUELA GALLARDO V. LYNCH                           65
    Gallardo explicitly referred to when “reaffirming” and
    “clarifying” them. Id. at 844. There is no reason to remand.13
    For the foregoing reasons, I respectfully dissent.
    13
    The majority Opinion states that the government’s supplemental
    briefing requested a remand so that the BIA could consider an alternative
    definition. But the government’s request was a fallback, apparently
    contingent on the panel deciding at Chevron step two that the BIA’s
    definition is “unreasonable.” See Resp’t’s Suppl. Mem. at 10 (“If the
    panel decides, however, the Board’s definition is unreasonable this Court
    should remand for the Board to provide an alternative definition of the
    ambiguous phrase.”). Although we certainly have the power to do so, it
    is inappropriate to remand to the BIA in this instance.
