United States Court of Appeals
                     For the First Circuit

No. 20-1593

                     CARLOS MONTEIRO SILVA,

                           Petitioner,

                               v.

              MERRICK B. GARLAND, Attorney General,

                           Respondent.

               PETITION FOR REVIEW OF AN ORDER OF
                THE BOARD OF IMMIGRATION APPEALS

                             Before

                      Howard, Chief Judge,
               Lynch and Barron, Circuit Judges.

     Kerry E. Doyle, with whom Graves and Doyle was on brief, for
petitioner.
     Evan P. Schultz, Trial Attorney, Office of Immigration
Litigation, Civil Division, with whom Brian Boynton, Acting
Assistant Attorney General, Civil Division, and Stephen J. Flynn,
Assistant Director, Office of Immigration Litigation, were on
brief, for respondent.

                        February 28, 2022
            LYNCH, Circuit Judge.         Petitioner Carlos Monteiro Silva

seeks review of a final order of removal issued by the Board of

Immigration Appeals ("BIA") in May 2020. The BIA dismissed Silva's

appeal of a decision by the immigration judge ("IJ") holding that

Silva was removeable under the Immigration and Nationality Act

("INA"), 8 U.S.C. § 1227(a)(2)(A)(iii), for having committed an

"aggravated felony" as defined under 8 U.S.C. § 1101(a)(43).                      The

IJ determined and the BIA affirmed that Silva's Massachusetts state

conviction for accessory after the fact to the crime of murder was

categorically an aggravated felony for purposes of the INA because

it met the definition of "an offense relating to obstruction of

justice."     Id. § 1101(a)(43)(S).        The IJ and BIA held that Silva

was ineligible for withholding of removal because he had committed

a   particularly    serious   crime    and   had      not   met    his   burden   to

establish that he was eligible for asylum or relief under the

Convention Against Torture ("CAT").

            Silva argues that the IJ and the BIA erred by applying

the categorical approach to determine that his state conviction

for   accessory     after   the    fact    was    "an   offense      relating     to

obstruction    of    justice."       Id.         He   argues      that   the   BIA's

interpretation of "an offense relating to obstruction of justice"

as including offenses where an investigation or proceeding is only

"reasonably foreseeable"          is an unreasonable interpretation of

§ 1101(a)(43)(S) and that the INA unambiguously requires that an

                                     - 2 -
obstruction of justice offense have some nexus to a pending or

ongoing   investigation        or   judicial    proceeding,      which   the

Massachusetts accessory-after-the-fact statute does not require.

For this and other reasons, Silva argues that deference under

Chevron, U.S.A., Inc. v. Natural Resources Defense Council, Inc.,

467 U.S. 837 (1984), does not apply to the BIA's interpretation

and that Silva's conviction for accessory after the fact is not

categorically an obstruction of justice offense triggering the

INA's aggravated felony grounds for removal.1

          We make two holdings, each of which provides a basis for

denying the petition.          First, we follow the mode of analysis

employed by the Supreme Court in Esquivel-Quintana v. Sessions,

137 S. Ct. 1562 (2017), and so apply "the normal tools of statutory

interpretation,"   id.    at    1569.   We     hold   the   generic   federal

definition of "an offense relating to obstruction of justice"

unambiguously does not require a nexus to a pending or ongoing

investigation or judicial proceeding.             Alternatively, we also

hold, employing Chevron analysis, that the BIA's interpretation

must be sustained.       Consonant with these holdings, we conclude

that the IJ and BIA properly concluded that Silva's Massachusetts

conviction for accessory after the fact is categorically an offense

relating to obstruction of justice and so rendered him removable

     1    We acknowledge and thank amici curiae for their brief in
support of the petitioner.

                                    - 3 -
as an aggravated felon.    We deny Silva's petition using each mode

of analysis.

                                 I.

A.    Massachusetts State Conviction

            Silva is a native and citizen of Cape Verde who was

admitted to the United States in 1989 as a lawful permanent

resident.

            In September 2017, Silva pleaded guilty in Massachusetts

to accessory after the fact in violation of Mass. Gen. Laws ch.

274, § 4.    That statute provides that,

            [w]hoever, after the commission of a felony,
            harbors, conceals, maintains or assists the
            principal felon or accessory before the fact,
            or gives such offender any other aid, knowing
            that he has committed a felony or has been
            accessory thereto before the fact, with intent
            that he shall avoid or escape detention,
            arrest, trial or punishment, shall be an
            accessory after the fact.

Id.   The offense to which Silva pleaded guilty occurred in 2003.

The September 2003 indictment that described the offense stated

that three men, not including Silva, "on April 28, 2003, did

assault and beat [the victim] with intent to murder him and by

such assault did kill and murder [the victim]."    As to Silva, the

indictment charged that he, "well knowing . . .     the [three men]

to have committed the felony . . . [,] did harbor, conceal,

maintain, assist or give any other aid to the said [three men],

with intent that the said [three men] should avoid and escape

                                - 4 -
detention, arrest, trial and punishment" by driving those three

men away from the scene of the murder.2          Silva was sentenced to

between four and five years in Massachusetts state prison.

B.   Removal Proceedings and BIA Decision

          In   January   2018,   the     U.S.   Department   of   Homeland

Security ("DHS") initiated removal proceedings against Silva.3          In

March 2019, DHS amended the charges of removal against Silva.

Those amended charges stated that Silva was removable for, among

other things, having been convicted of an aggravated felony in the

form of "an offense relating to obstruction of justice . . . for

which the term of imprisonment was at least one year."              See 8

U.S.C. §§ 1227(a)(2)(A)(iii), 1101(a)(43)(S).4        Silva objected to

those amended charges of removal.

     2    Silva's plea leaves no doubt that he intended to obstruct
a reasonably foreseeable investigation.        To the extent our
dissenting colleague argues to the contrary, the state court
conviction precludes such a holding.
     3    This case has a long procedural history involving an
initial termination of removal proceedings against Silva and a
reinstatement of proceedings against him on different charges of
removal. We describe only those later proceedings which led to
this appeal.
     4    The amended charges also stated that Silva was
removeable for having been convicted of two or more crimes
involving moral turpitude. See 8 U.S.C. § 1227(a)(2)(A)(ii). That
charge of removal was based on Silva's Massachusetts accessory-
after-the-fact conviction and an earlier Massachusetts state
conviction for receiving stolen property in violation of Mass.
Gen. Laws ch. 266, § 60. The IJ and the BIA ultimately did not
rely on this alternative ground for removal because of updated
criminal documents filed with the IJ by Silva reflecting that a
Massachusetts state court had allowed his motion to vacate his

                                 - 5 -
            In a written decision in May 2019, the IJ held that

Silva's    Massachusetts   accessory-after-the-fact   conviction   was

categorically an offense relating to obstruction of justice under

the INA and so was a proper ground for removal as an aggravated

felony.5     The IJ relied on the BIA's decision in        Matter of

Valenzuela Gallardo, 27 I. & N. Dec. 449, 452-60 (B.I.A. 2018),

underlying removal order vacated in Valenzuela-Gallardo v. Barr,

968 F.3d 1053 (9th Cir. 2020).6

plea for several prior convictions, including his conviction for
receiving stolen property. They declined to decide what effect,
if any, that state court decision would have on Silva's removal
proceedings. The only issue for our review is the IJ's and the
BIA's determination about the aggravated felony charge for
removal.
     5    "[T]o determine whether an alien's conviction qualifies
as an aggravated felony under th[e INA], [courts and the agency]
'employ a categorical approach by looking to the statute . . . of
conviction, rather than to the specific facts underlying the
crime.'" Esquivel-Quintana, 137 S. Ct. at 1567-68 (ellipsis in
original) (quoting Kawashima v. Holder, 565 U.S. 478, 483 (2012));
see also De Lima v. Sessions, 867 F.3d 260, 262-63 (1st Cir. 2017).
"Under that approach, we ask whether 'the state statute defining
the crime of conviction categorically fits within the generic
federal definition of a corresponding aggravated felony.'"
Esquivel-Quintana, 137 S. Ct. at 1568 (some internal quotation
marks omitted) (quoting Moncrieffe v. Holder, 569 U.S. 184, 190
(2013)); see also De Lima, 867 F.3d at 262-63. "[W]e presume that
the          state         conviction          'rested         upon
. . . the least of th[e] acts' criminalized by the statute, and
then we determine whether that conduct would fall within the
[generic] federal definition of the crime."      Esquivel-Quintana,
137 S. Ct. at 1568 (second and third alterations in original)
(quoting Johnson v. United States, 559 U.S. 133, 137 (2010)); see
also De Lima, 867 F.3d at 263.
     6    Valenzuela Gallardo, applying the categorical approach,
held that the generic definition of obstruction of justice includes

                                 - 6 -
           Silva then filed applications for asylum, withholding of

removal, and protection under the CAT.              In a written decision in

December 2019, the IJ denied all three forms of relief from

removal.      The     IJ   concluded     that    Silva's    aggravated    felony

conviction for accessory after the fact rendered him statutorily

ineligible     for     asylum,     see    8     U.S.C.     § 1158(b)(2)(A)(ii),

(b)(2)(B)(i), and that the conviction was a "particularly serious

crime" which barred his application for withholding of removal,

see id. § 1231(b)(3)(B)(ii).         The IJ also concluded that Silva did

not provide sufficient evidence to support his application for CAT

protection.

           Silva appealed to the BIA.            In May 2020, the BIA denied

that appeal.      The BIA, referencing Matter of Valenzuela Gallardo,

adopted and affirmed the IJ's decision, holding that Silva's

Massachusetts          accessory-after-the-fact              conviction      was

categorically an aggravated felony relating to obstruction of

justice.     The BIA also held that the IJ did not clearly err in

finding    that      Silva's     Massachusetts      accessory-after-the-fact

crimes involving: "(1) an affirmative and intentional attempt
(2) that is motivated by a specific intent (3) to interfere with
an investigation or proceeding that is ongoing, pending, or
'reasonably foreseeable by the defendant.'" 27 I. & N. Dec. at
456 (emphasis added) (quoting Marinello v. United States, 138 S.
Ct. 1101, 1110 (2018)) (citing United States v. Aguilar, 515 U.S.
593, 599 (1995)).   Applying that generic federal definition of
obstruction of justice, the IJ concluded that the elements of
Silva's Massachusetts accessory-after-the-fact conviction were a
categorical match.

                                       - 7 -
conviction    was    a   particularly     serious      crime    for   purposes     of

withholding of removal, and affirmed the denial of all forms of

relief.

             This timely petition for review followed.

                                        II.

             Silva   first     argues    that    the   Court     should     give   no

deference to the BIA's interpretation in Matter of Valenzuela

Gallardo of "an offense relating to obstruction of justice" for

various reasons.         He also argues that, even if his Massachusetts

accessory-after-the-fact         conviction      is    an      aggravated     felony

relating to obstruction of justice, the BIA erred in determining

that the conviction is a "particularly serious crime" for purposes

of barring him from withholding of removal.7

             Where, as here, "the BIA adopts and affirms an IJ's

decision, we review the IJ's decision 'to the extent of the

adoption, and the BIA's decision as to [any] additional ground.'"

Sunoto v. Gonzales, 504 F.3d 56, 59-60 (1st Cir. 2007) (alteration

in original) (quoting Berrio-Barrera v. Gonzales, 460 F.3d 163,

167   (1st   Cir.    2006)).      We    review    de   novo     the   BIA's   legal

      7   Silva   does   not  challenge   the   IJ's   and   BIA's
determination that his conviction for accessory after the fact, if
found to be an aggravated felony, would render him statutorily
ineligible for asylum. Nor does he challenge the IJ's and BIA's
denial of his application for deferral of removal under the CAT.
Any challenge to those two determinations has been waived. See
Bekele v. Lyft, Inc., 918 F.3d 181, 186 (1st Cir. 2019).

conclusions,        including      its    determination      that     Silva's

Massachusetts accessory-after-the-fact conviction is an aggravated

felony.     See Lecky v. Holder, 723 F.3d 1, 4 (1st Cir. 2013).              We

review the BIA's factual findings under a deferential standard,

upholding them "as long as they are 'supported by reasonable,

substantial, and probative evidence on the record considered as a

whole.'"    Sanabria Morales v. Barr, 967 F.3d 15, 19 (1st Cir. 2020)

(quoting Thapaliya v. Holder, 750 F.3d 56, 59 (1st Cir. 2014)).

A.   Applying the Tools of Statutory Interpretation as Applied by
     the Supreme Court in Esquivel-Quintana, the Conviction for
     Accessory After the Fact Is an Aggravated Felony "Relating to
     Obstruction of Justice" Under the INA

            We turn first to Silva's argument that his Massachusetts

accessory-after-the-fact        conviction    is   not   categorically      "an

offense relating to obstruction of justice" because, he alleges,

it does not require a nexus to a pending or ongoing investigation

or judicial proceeding.         In Esquivel-Quintana, the Supreme Court

addressed    a   similar   issue    of   whether   the   petitioner's    state

conviction    for    unlawful   sexual    intercourse    with   a   minor   was

categorically an offense for "sexual abuse of a minor" under 8

U.S.C. § 1101(a)(43)(A). 137 S. Ct. at 1567. Applying "the normal

tools of statutory interpretation," id. at 1569, the Court held

that "in the context of statutory rape offenses that criminalize

sexual intercourse based solely on the age of the participants,

the generic federal definition of sexual abuse of a minor requires

                                     - 9 -
that the victim be younger than 16," id. at 1568.    It held that

"[b]ecause the California statute at issue in this case does not

categorically fall within that definition, a conviction pursuant

to it is not an aggravated felony under § 1101(a)(43)(A)."     Id.8

The Court determined the meaning of the statutory definition based

on the text, the structure of the statute and closely related

federal statutes, the consensus of state criminal statutes, and

definitions from other sources, like the Model Penal Code.   Id. at

1569-72.   Because it determined the unambiguous meaning of the

statute, the Court held it was unnecessary to consider the Chevron

and rule of lenity issues.   Id. at 1572.

           We initially, as we said, follow the same analytical

path as the Supreme Court in Esquivel-Quintana and consider the

same factors to determine the generic federal definition of "an

offense relating to obstruction of justice."

     8    In Esquivel-Quintana, the petitioner had been convicted
under a California statute criminalizing "unlawful sexual
intercourse with a minor who is more than three years younger than
the perpetrator" in which the statute defined "minor" as "a person
under the age of 18 years." 137 S. Ct. at 1567 (quoting Cal. Penal
Code § 261.5(a), (c)). The petitioner was convicted under that
statute for having had "consensual sexual intercourse . . . [with]
a 17-year-old" when he was 21. Id.

                              - 10 -
          1.     The Text of the Statute as a Whole Shows That the
                 Generic Federal Definition of "An Offense Relating
                 to Obstruction of Justice" Must Be Construed to
                 Include Accessory After the Fact

          We begin with the text of the INA.   See id. at 1568-69;

United States v. De la Cruz, 998 F.3d 508, 513 (1st Cir. 2021).

"[W]e accord the statutory text its ordinary meaning by reference

to the specific context in which that language is used, and the

broader context of the statute as a whole."    De la Cruz, 998 F.3d

at 513 (internal quotation marks omitted) (quoting Recovery Grp.,

Inc. v. Comm'r, 652 F.3d 122, 125 (1st Cir. 2011)).    When resolving

a dispute over the meaning of a statute, we "normally seek[] to

afford the law's terms their ordinary meaning at the time Congress

adopted them."   Id. at 515 (quoting Niz-Chavez v. Garland, 141 S.

Ct. 1474, 1480 (2021)); see also Esquivel-Quintana, 137 S. Ct. at

1569-72 (interpreting 8 U.S.C. § 1101(a)(43)(A) according to what

its ordinary meaning was in 1996 when Congress added that provision

to the INA).

                 a.   The Text of § 1101(a)(43)(S) Supports That
                      Accessory After the Fact Is "An Offense
                      Relating to Obstruction of Justice"

          Section 1101(a)(43)(S), which provides that "an offense

relating to obstruction of justice" is an aggravated felony, was

added to the INA in 1996.    See Antiterrorism and Effective Death

Penalty Act of 1996, Pub. L. No. 104-132, § 440(e)(8), 110 Stat.

1214,   1278;     Illegal   Immigration   Reform      and   Immigrant

                               - 11 -
Responsibility Act of 1996, Pub. L. No. 104-208, § 321(a)(11), 110

Stat. 3009, 3009-628.        The INA does not define "obstruction of

justice."    So we turn to reliable contemporaneous dictionaries to

determine that term's ordinary meaning.               See Esquivel-Quintana,

137 S. Ct. at 1569-70; De la Cruz, 998 F.3d at 515.

            Black's Law Dictionary defined "obstructing justice" as

"[i]mpeding or obstructing those who seek justice in a court, or

those who have duties or powers of administering justice therein,"

"attempt[ing] to prevent, or . . . prevent[ing], the execution of

lawful process," or "obstructing the administration of justice in

any way -- as by hindering witnesses from appearing, assaulting

process servers, influencing jurors, obstructing court orders or

criminal    investigations."       Obstructing        Justice,     Black's     Law

Dictionary 1077 (6th ed. 1990).           Another dictionary at that time

defined "obstruction of justice" as "the crime or act of willfully

interfering    with   the     process     of    justice   and     law   esp.    by

influencing,      threatening,    harming,       or   impeding     a    witness,

potential witness, juror, or judicial officer or legal officer or

by   furnishing    false    information    in    or   otherwise    impeding    an

investigation or legal process."          Obstruction of Justice, Merriam-

Webster's Dictionary of Law 337 (1996).

            Indeed, Bryan Garner, a noted legal commentator often

cited by the Supreme Court, see, e.g., Esquivel-Quintana, 137 S.

Ct. at 1569; Van Buren v. United States, 141 S. Ct. 1648, 1657

                                   - 12 -
(2021); Bostock v. Clayton Cnty., 140 S. Ct. 1731, 1749 (2020);

Lockhart v. United States, 577 U.S. 347, 351 (2016), defined

"obstruction     of     justice"          as   "interference     with     the       orderly

administration of law" and stated that it was "a broad phrase that

captures every willful act of corruption, intimidation, or force

that tends somehow to impair the machinery of the civil or criminal

law," Obstruction of Justice, B. Garner, A Dictionary of Modern

Legal   Usage    611    (2d     ed.       1995).      These   definitions       did      not

explicitly require that the obstructive conduct be committed in

relation    to   a     pending       or    ongoing    investigation       or    judicial

proceeding.      Acting as an accessory to a crime after the fact by

providing some sort of aid to the principal with the intent that

the principal evade capture, trial, or punishment, even if there

is not then a pending or ongoing investigation or proceeding,

certainly    fits      within    these         definitions     of   "obstruction         of

justice."

            Furthermore,         the       relevant     statutory       term        to   be

interpreted is not just "obstruction of justice"; rather, it is

"an   offense    relating       to    obstruction       of    justice."         8    U.S.C.

§ 1101(a)(43)(S) (emphasis added).                   The Supreme Court has stated

in other contexts that the ordinary meaning of the phrase "relating

to" is "a broad one," holding that it normally means "connection

with or reference to" something else.                     Morales v. Trans World

                                           - 13 -
Airlines, Inc., 504 U.S. 374, 383-84 (1992).9   The generic federal

definition of § 1101(a)(43)(S) must necessarily encompass more

than the definition of "obstruction of justice" itself, including

offenses connected with or in reference to that concept.       Indeed,

we "must give effect, if possible, to every clause and word of a

statute."   Loughrin v. United States, 573 U.S. 351, 358 (2014)

(quoting Williams v. Taylor, 529 U.S. 362, 404 (2000)).       To limit

the scope of § 1101(a)(43)(S) to only the narrowest possible

reading of obstruction of justice would violate that core tenet of

statutory   interpretation.   Accordingly,   even   if   we   read   the

dictionary detentions more narrowly, we would still conclude that

Congress intended to cover offenses like Massachusetts accessory-

after-the-fact.

     9    Silva relies on the Supreme Court's decision in Mellouli
v. Lynch, 575 U.S. 798 (2015), for the proposition that the
"relating to" language in § 1101(a)(43)(S) must be given a more
restrictive reading.    Mellouli is distinguishable.   There, the
Supreme Court concluded that the "relating to" language in a
different provision of the INA had to be given a narrower reading
within the context of the statute because that provision included
a cross-reference to another specific statute further defining the
statute of conviction for purposes of removal. See id. at 801-
02, 808-12, 808 n.9. Here, there is no cross-reference to another
statute which defines "obstruction of justice" or requires a nexus
to a pending or ongoing investigation or judicial proceeding.

                b.       The   Text  and   Structure  of  Surrounding
                         Provisions of the INA Support That Accessory
                         After the Fact Is "An Offense Relating to
                         Obstruction of Justice"

            In addition to the text of the specific provision at

issue, we also consider the text and structure of the INA as a

whole.   See Esquivel-Quintana, 137 S. Ct. at 1571 (considering the

INA's disparate use of cross-references to other statutes in

interpreting a particular provision).       Most of the offenses listed

as   "aggravated     felon[ies]"    under   § 1101(a)(43)    specifically

include cross-references to other federal statutes which define

those offenses, while no such cross-reference is included to define

"an offense relating to obstruction of justice."       Compare 8 U.S.C.

§ 1101(a)(43)(B)-(F), (H)-(J), (K)(ii)-(iii), (L), (M)(ii), (N)-

(P) (all containing cross-references to other statutes), with id.

§ 1101(a)(43)(S) (containing none). See also id. § 1101(a)(43)(A),

(G), (K)(i), (M)(i), (Q)-(R), (T) (also containing no cross-

references to other statutes).          Moreover, § 1101(a)(43)(S) is

among only a few of the aggravated felonies under the INA in which

Congress deliberately used the expansive qualifier "relating to"

to   describe      the    aggravated   felony.     Compare     8     U.S.C.

§ 1101(a)(43)(B)-(F), (H)-(J), (K)(ii)-(iii), (L), (M)(ii), (N)-

(P) (all using instead something like "defined in" or "described

in" followed by a cross-reference to another statute defining the

offense),     with       id.   § 1101(a)(43)(S).      See     also      id.

                                   - 15 -
§ 1101(a)(43)(K)(i), (Q)-(R), (T) (using "relates to" or "relating

to" without a cross-reference to another statute).

            Congress easily could have included cross-references in

§ 1101(a)(43)(S) to other statutes to define "an offense relating

to obstruction of justice," but it chose not to do so.               This shows

that   Congress   did       not   intend    for   "an   offense    relating   to

obstruction of justice" to be read restrictively to apply only to

offenses    defined    by    specific      federal   obstruction    of   justice

statutes.    See Russello v. United States, 464 U.S. 16, 23 (1983)

("[W]here Congress includes particular language in one section of

a statute but omits it in another section of the same Act, it is

generally presumed that Congress acts intentionally and purposely

in the disparate inclusion or exclusion." (alteration in original)

1972))); De la Cruz, 998 F.3d at 517-18.

            2.    The Statute's Relationship to Other Federal
                  Statutes Confirms That Accessory After the Fact Is
                  "An Offense Relating to Obstruction of Justice"

            In addition to the text of § 1101(a)(43)(S) and the other

text of the INA, we consider "closely related federal statute[s]"

in determining the generic federal definition of an aggravated

felony offense.       Esquivel-Quintana, 137 S. Ct. at 1570-71; cf. De

la Cruz, 998 F.3d at 517-18.

                        and the Federal Bribery Statute Support That
                        the Generic Federal Definition Does Not
                        Require a Nexus to a Pending or Ongoing
                        Investigation or Judicial Proceeding

           The federal accessory-after-the-fact statute, 18 U.S.C.

§ 3, is relevant to determining the generic federal definition of

"an offense relating to obstruction of justice."               That statute

provides that "[w]hoever, 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."

Id.    "[H]inder[ing] or prevent[ing]" is a type of obstructive

conduct and "apprehension, trial or punishment" are all different

stages in the process of "justice."              In that way, the federal

accessory-after-the-fact       statute     relates   to   "obstruction    of

justice."10      That statute does not require a nexus to a pending or

ongoing investigation or judicial proceeding and reaches conduct

preceding an investigation or proceeding. See, e.g., United States

v. Neal, 36 F.3d 1190, 1195, 1211 (1st Cir. 1994) (affirming the

      10  The   Massachusetts   accessory-after-the-fact   statute
prohibits "harbor[ing], conceal[ing], maintain[ing] or assist[ing]
the principal felon or accessory before the fact, or giv[ing] such
offender any other aid, knowing that he has committed a felony or
has been accessory thereto before the fact, with intent that he
shall avoid or escape detention, arrest, trial or punishment."
Mass. Gen. Laws ch. 274, § 4. That statute covers substantially
the same conduct as that proscribed by the federal accessory-
after-the-fact statute.

                                   - 17 -
defendant's conviction for accessory after the fact where he

provided aid to his co-defendants immediately after they robbed a

bank and helped them to escape apprehension).

            This understanding of the federal accessory-after-the-

fact statute as relating to obstruction of justice is bolstered by

case law from the federal circuit courts of appeal before 1996.

See United States v. Brown, 33 F.3d 1002, 1004 (8th Cir. 1994)

(stating that "[t]he gist of being an accessory after the fact

lies essentially in obstructing justice by rendering assistance to

hinder or prevent the arrest of the offender after he [or she] has

committed the crime" (alteration in original) (emphasis added)

(quoting United States v. Barlow, 470 F.2d 1245, 1252-53 (D.C.

Cir. 1972))); United States v. Huppert, 917 F.2d 507, 510 (11th

Cir. 1990) (same), superseded by statute in other part, U.S. Sent'g

Guidelines Manual § 2J1.2(c)(1), cmt. (U.S. Sent'g Comm'n 1991);

United States v. Balano, 618 F.2d 624, 631 (10th Cir. 1979) (same),

abrogated in other part by Richardson v. United States, 468 U.S.

317 (1984); United States v. Willis, 559 F.2d 443, 444 (5th Cir.

1977) (same); Gov't of V.I. v. Aquino, 378 F.2d 540, 553 & n.19

(3d Cir. 1967) (same); see also Pugin v. Garland, 19 F. 4th 437,

447 n.8 (4th Cir. 2021) (collecting cases).             This consistent

interpretation of the federal accessory-after-the-fact statute

when   §   1101(a)(43)(S)   was   enacted   supports   interpreting   "an

offense relating to obstruction of justice" to include accessory

                                  - 18 -
after the fact.        See Guerrero-Lasprilla v. Barr, 140 S. Ct. 1062,

1072 (2020) ("We normally assume that Congress is 'aware of

relevant    judicial     precedent'     when   it   enacts     a    new   statute."

(quoting Merck & Co. v. Reynolds, 559 U.S. 633, 648 (2010))).

            Another     federal   statute      we   consider       is   the   statute

related to bribery of a witness.11              See 18 U.S.C. § 201.             The

federal witness bribery statute includes the giving or offering of

bribes to witnesses who give testimony at a hearing before a

congressional committee.          Id. § 201(b)(3), (c)(2).              The witness

bribery statute also supports our reading of § 1101(a)(43)(S) as

not requiring a nexus to a pending or ongoing investigation or

judicial proceeding.

                  b.     Several Obstruction of Justice Offenses Under
                         18 U.S.C. Chapter 73 Do Not Require a Nexus to
                         a Pending or Ongoing Investigation or Judicial
                         Proceeding

            Silva argues that we should look exclusively to Chapter

73 of Title 18 of the U.S. Code, which is titled "Obstruction of

Justice,"    to   determine       the   generic      federal        definition    of

"obstruction of justice."          He asserts that Chapter 73 cannot be

     11   Amici argue that, because the phrase "obstruction of
justice" appears next to "perjury or subornation of perjury" and
"bribery of a witness" in § 1101(a)(43)(S), all three must be read
to share the common characteristic of a nexus to a pending or
ongoing investigation or judicial proceeding.     We do not agree
that the federal witness bribery statute requires a nexus to a
pending or ongoing judicial proceeding and so this cannot be a
common characteristic to all three offenses listed.

                                      - 19 -
reviewed for its components but must be read as a whole to require

a   nexus   to   a   pending    or    ongoing    investigation   or     judicial

proceeding.      We disagree.        Chapter 73 contains many offenses and

cannot be read as a whole.

            Section    1512,    which    is     titled   "[t]ampering    with   a

witness, victim, or an informant," specifically provided in 1996

that "[f]or the purposes of this section . . . an official

proceeding need not be pending or about to be instituted at the

time of the offense."12        18 U.S.C. § 1512(e)(1) (1996); see Pugin,

19 F.4th at 445.13      Nor does the text of § 1511, which prohibited

the "[o]bstruction of State or local law enforcement,"14 require

      12  The Ninth Circuit reads § 1512 as "underscor[ing] that
the common understanding at the time § 1101(a)(43)(S) was enacted
into law was that an obstruction offense referred only to offenses
committed while proceedings were ongoing or pending. [For] [i]f
that were not the case, it would not have been necessary for
Congress to make clear that § 1512 operates differently than the
other provisions in Chapter 73." Valenzuela-Gallardo, 968 F.3d at
1065-66. Not so. A proceeding that is about to be instituted is
not pending or ongoing, but it could be reasonably foreseeable.
The "about to be instituted" language thus suggests that Congress
believed that obstruction of justice could encompass the
frustration of official proceedings that are not yet in place.
     13   In Pugin, the Fourth Circuit relied on Chevron deference
to conclude that Virginia accessory after the fact is "an offense
relating   to   obstruction   of    justice"   for   purposes   of
§ 1101(a)(43)(S). 19 F.4th at 439. We find much of the Fourth
Circuit's analysis persuasive.
     14   In any event, as to those Chapter 73 offenses which do
require a nexus to a pending or ongoing investigation or judicial
proceeding, it is clear that Congress did not intend for those
specific offenses to define "an offense relating to obstruction of
justice" for purposes of § 1101(a)(43)(S). For that same reason,
we reject Silva's argument that we cannot consider the federal

                                      - 20 -
that an investigation or judicial proceeding be pending or ongoing.

Id. § 1511 (1996).

           Indeed, as the Fourth Circuit recently held, obstruction

of justice for the purposes of § 1101(a)(43) is not limited to

"the narrow confines of Chapter 73."         Pugin, 19 F.4th at 445.

                c.    Congress Intended Obstruction of Justice to be
                      Read More Broadly Than Other Aggravated
                      Felonies

           Congress specifically included cross-references to other

federal   statutes   in   defining   other    offenses   that   constitute

aggravated felonies under § 1101(a)(43), but it included no cross-

reference to Chapter 73 or any particular offense under that

chapter to define "an offense relating to obstruction of justice."

Congress also deliberately used the qualifier "relating to" in

conjunction with "obstruction of justice" in § 1101(a)(43)(S),

even though it did not do so for most of the other offenses listed

as aggravated felonies under the INA.          This shows that Congress

clearly did not intend for "an offense relating to obstruction of

justice" to be restricted only to the obstruction of justice

offenses listed under Chapter 73, let alone to any particular

Chapter 73 offense that requires a nexus to a pending or ongoing

accessory-after-the-fact statute, 18 U.S.C. § 3, because it is not
located under Chapter 73.

448; Russello, 464 U.S. at 23; De la Cruz, 998 F.3d at 517-18; see

also Esquivel-Quintana, 137 S. Ct. at 1571 (noting that "many other

aggravated felonies in the INA are defined by cross-reference to

other provisions of the United States Code," and relying on a

related federal statute "for evidence of the meaning of [the

aggravated felony offense], but not as providing the complete or

exclusive definition" where there was no such cross-reference);

cf. Mellouli, 575 U.S. at 808 n.9, 811 n.11 (noting the importance

of the relationship between the language "relating to" in the

     15   For this reason, the Supreme Court's decision in United
States v. Aguilar, 515 U.S. 593 (1995), also does not support
Silva's reading of § 1101(a)(43)(S).      Aguilar held that, for
purposes of the "catchall" provision of 18 U.S.C. § 1503, which
criminalizes "[i]nfluencing or injuring [an] officer or [a] juror
generally," "[t]he 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." 515 U.S. at 599 (emphasis added); see
also id. at 600-01 (holding that making false statements to an
investigating officer "who might or might not testify before a
grand jury" was insufficient to violate the catchall provision of
§ 1503); 18 U.S.C. § 1503(a) (1996) (prohibiting "corruptly or by
threats or force, or by any threatening letter or communication,
influenc[ing], obstruct[ing], or imped[ing], or endeavor[ing] to
influence, obstruct, or impede, the due administration of
justice").
     That decision addressed only the specific statute at issue
and did not establish the requirements of "obstruction of justice"
more generally.   Nor does § 1101(a)(43)(S) incorporate § 1503's
particular definition of "obstruction of justice" through cross-
reference. Even Silva acknowledges that a nexus to a pending or
ongoing investigation would be enough to satisfy his purported
nexus requirement.

statute and a specific statutory cross-reference in applying the

categorical approach).16

          3.   Other Sources of the Statute's Meaning Support That
               Accessory After the Fact Is "An Offense Relating to
               Obstruction of Justice"

          In addition to the text and structure of the statute and

closely related federal statutes, we also consider other indicia

identified in Esquivel-Quintana in determining the generic federal

definition of "an offense relating to obstruction of justice."

               a.   A Consensus of State Obstruction of Justice
                    Statutes Confirm That "An Offense Relating to
                    Obstruction of Justice" Does Not Require a
                    Nexus to a Pending or Ongoing Investigation or
                    Judicial Proceeding

          One of those other sources we consider is a consensus of

"state criminal codes" which "we look to . . . for additional

evidence about the generic meaning of" an offense.       Esquivel-

     16   Silva relies on the Third Circuit decision in Flores v.
Attorney General, 856 F.3d 280, 292-96 (3d Cir. 2017), and the
Ninth Circuit decision in Valenzuela Gallardo, which held that
state convictions for accessory after the fact were not offenses
relating to obstruction of justice because they lacked a nexus
requirement.    We find neither persuasive.       Both Flores and
Valenzuela Gallardo relied exclusively on offenses listed under
Chapter 73 in defining the generic federal definition of §
1101(a)(43)(S) and discounted or did not consider other evidence
of the statute's meaning. See Flores, 856 F.3d at 287-96; id. at
297-301 (Shwartz, J., concurring, in part, and dissenting, in part)
(disagreeing with the majority that the court was limited to
consideration of only Chapter 73 offenses to determine the generic
federal definition of "an offense relating to obstruction of
justice" and concluding that a South Carolina accessory-after-the-
fact conviction related to obstruction of justice); Valenzuela
Gallardo, 968 F.3d at 1062-69.

Quintana, 137 S. Ct. at 1571; see also id. at 1571 n.3 (noting

that a multijurisdictional analysis of state criminal codes can

aid   interpretation         by    providing    "useful   context").         When

§ 1101(a)(43)(S) was added to the INA, seventeen states used

phrases like "obstruction of justice" or "obstructing justice" to

define certain crimes.            See Colo. Rev. Stat. §§ 18-8-101 to -116

(1996); Fla. Stat. §§ 843.01 to .19 (1996); Haw. Rev. Stat. § 710-

Code Ann. § 18.2-460 (1996); Wis. Stat. § 946.65 (1996). Of these,

only three may have limited the obstruction of justice offenses to

those involving a pending or ongoing investigation or judicial

proceeding.     See Haw. Rev. Stat. § 710-1072.5 (1996); Ind. Code

§ 35-44-3-4 (1996); Wis. Stat. § 946.65 (1996); see also Pugin, 19

F.4th at 445.        Of the other fourteen, at least thirteen did not

have such a requirement.           See Colo. Rev. Stat. § 18-8-105 (1996);

Fla. Stat. §§ 843.01 to .02, .08 (1996); 720 Ill. Comp. Stat. 5/31-

4   (1996);   Iowa    Code    §§ 719.1    to    .2   (1996);   La.   Stat.   Ann.

Ann. tit. 13, § 3015 (1996).

            And the obstruction of justice statutes in four of these

latter states proscribed conduct which would have been punishable

under the federal accessory-after-the-fact statute.        See Colo.

Rev. Stat. § 18-8-105 (1996); Mont. Code Ann. § 45-7-303(2)(a)-

Code Ann. § 76-8-306(b), (e) (1996).       That the vast majority of

jurisdictions with obstruction of justice offenses did not limit

that concept to only offenses with a nexus to a pending or ongoing

investigation or judicial proceeding further confirms our reading

of the generic federal definition.      See Esquivel-Quintana, 137 S.

Ct. at 1571-72.

            The Model Penal Code and Federal Sentencing Guidelines

also support that "an offense relating to obstruction of justice"

includes accessory after the fact.       See id. at 1571 (citing the

Model Penal Code as evidence of the generic meaning of a term in

the INA).   When § 1101(a)(43)(S) was enacted, the Model Penal Code

                               - 25 -
listed "Hindering Apprehension or Prosecution," which proscribes

conduct like that proscribed in the federal accessory-after-the-

fact statute, under the article for "Obstructing Governmental

Operations; Escapes."     Model Penal Code § 242.3 (Am. L. Inst.

1985).    In describing the offense of hindering apprehension or

prosecution of another, the explanatory notes to the Model Penal

Code states that the "offense covers the common law category of

accessory after the fact but breaks decisively with the traditional

concept that the accessory's liability derives from that of his

principal . . . [and instead provides that the accessory] is

convicted . . . for an independent offense of obstruction of

justice."    Id. § 242.1 explanatory note; see also Pugin, 19 F.4th

at 445.

            The Federal Sentencing Guideline for "Obstruction of

Justice" in effect in 1996 cross-referenced the guideline for

"Accessory After the Fact."     See U.S. Sent'g Guidelines Manual

§ 2J1.2(c) (U.S. Sent'g Comm'n 1995).       The commentary to the

"Obstruction of Justice" guideline stated that "[b]ecause the

conduct covered by this guideline is frequently part of an effort

to avoid punishment for an offense that the defendant has committed

or to assist another person to escape punishment for an offense,

a cross reference to [the Accessory After the Fact guideline] is

provided."    Id. § 2J1.2 cmt. background (emphasis added).     The

commentary and cross-reference are further support that there was

                               - 26 -
an understood connection between accessory after the fact and

obstruction of justice when § 1101(a)(43)(S) was adopted.

          4.    Even Assuming Arguendo That There Must Be a Nexus
                to an Investigation for the Normal Accessory-After-
                the-Fact Crime, That Nexus Is Satisfied

          Assuming arguendo that § 1101(a)(43)(S) requires any

nexus to an investigation, whether actually pending or in the

offing,   the   Massachusetts   accessory-after-the-fact   crime   and

conviction easily satisfies it.17

          Mass. Gen. Laws ch. 274, § 4 provides:

          [w]hoever, after the commission of a felony,
          harbors, conceals, maintains or assists the
          principal felon or accessory before the fact,
          or gives such offender any other aid, knowing
          that he has committed a felony or has been
          accessory thereto before the fact, with intent
          that he shall avoid or escape detention,
          arrest, trial or punishment, shall be an
          accessory after the fact.

     17   Our dissenting colleague overreads our assumption in
this section that a nexus is required.    We find in the statutory
text no requirement for a nexus, see supra Part II.A.1, and so in
our de novo review under Esquivel-Quintana we do not graft a nexus
requirement on to the statute. The BIA, however, interpreted the
statute to mean that an offender must "interfere with an
investigation or proceeding that is ongoing, pending, or
'reasonably foreseeable'" Matter of Valenzuela Gallardo, 27 I. &
N. Dec. at 456 (quoting Marinello, 138 S. Ct. at 1110). To the
extent the statute is ambiguous, the BIA's interpretation of the
nexus requirement is certainly reasonable and due deference. See
infra Part II.B. Our de novo analysis makes clear, though, that
the BIA could also dispense with its nexus requirement. Either
construction would "fill the statutory gap in reasonable fashion."
Negusie v. Holder, 555 U.S. 511, 523 (2009)

                                - 27 -
To be convicted under that statute, the accessory must act with

specific intent to enable a felon to "avoid or escape detention,

arrest, trial, or punishment."   Absent an investigation, there can

be no prosecution and no detention, arrest, trial, or punishment

to avoid or escape.

          In determining the least culpable conduct that violates

the statue, Moncrieffe v. Holder directs us to "focus on the

minimum conduct criminalized by the state statue," rather than

"apply 'legal imagination' to the state offense."    569 U.S. 184,

191 (2013).    Unlike the dissent, we look not to hypothetical

conduct but to the "the least serious conduct for which there is

a 'realistic probability' of charge and conviction." United States

v. Starks, 861 F.3d 306, 315 (1st Cir. 2017) (quoting id.).

Looking at the mine run of prosecutions, we see none for aiding

and abetting less serious felonies.    When we look at the seventy

Massachusetts state court opinions on Westlaw that cite § 4, the

overwhelming majority are convictions for accessory after the fact

to homicide.   Those that do not involve homicide, involve other

serious offenses: armed robbery, e.g., Commonwealth v. Ayoub, 32

N.E.3d 369 (Mass. App. Ct. 2015) (table); assault with a dangerous

weapon, e.g., Commonwealth v. Nick N., 952 N.E.2d 991 (Mass. App.

Ct. 2011) (table); arson, Commonwealth v. Sokorelis, 150 N.E. 197

(Mass. 1926); kidnapping, Commonwealth v. Eagan, 259 N.E.2d 548

(Mass. 1970); escape from prison, e.g., Commonwealth v. Holiday,

                             - 28 -
206 N.E.2d 691 (Mass. 1965); extortion, Commonwealth v. Cachopa,

18 N.E.3d 1137 (Mass. App. Ct. 2014) (table); dealing cocaine,

Commonwealth v. St. Pierre, 786 N.E.2d 438 (Mass. App. Ct. 2003)

(table); and larceny, e.g., Commonwealth v. Kudrya, 843 N.E.2d

1117 (Mass. App. Ct. 2006) (table).    Indeed, the serious nature of

the crimes actually prosecuted under § 4 supports our holding that

the least culpable conduct likely to be charged under the provision

includes a fair probability of criminal investigation.18   In fact,

the serious crimes for which accessory-after-the-fact prosecutions

have been brought by their nature would inform any person acting

as an accessory that there will be an investigation resulting in

"escape detention, arrest, trial or punishment."19     Further, the

     18   Our dissenting colleague relies on Marinello v. United
States, 138 S. Ct. 1101 (2018), to support his contention that a
felonious money launderer in Massachusetts must have more than
mere awareness that the authorities might catch on to his illegal
financial scheme. Dissenting Op. at 46-50 (citing Marinello, 138
S. Ct. at 1110).      In the dissenting opinion's telling, the
government failed to establish that its investigation of Marinello
was "reasonably foreseeable," because it could show no more than
that mere awareness. Id. at 8 (quoting Marinello, 131 S. Ct. at
1110). But in Marinello, the Court had no opportunity to weigh in
on   whether   the   government    had   presented    evidence   of
foreseeability; the trial judge did not instruct the jury on
foreseeability as Marinello requested, Marinello, 138 S. Ct. at
1105, and the Court vacated and remanded, id. at 1110. Thus, the
opinion cannot be read -- as our dissenting colleague does -- to
support a categorical rule for financial criminals.
     19   We note that on the facts here, an investigation to quote
the dissent and "[t]o use a maritime analogy" is easily thought to
be "in the offing," Dissenting Op. at 46 (quoting Marinello, 138
S. Ct. at 1110). While the dissent seems to treat the offing as
a term of proximity, it refers, in the maritime sense, to "[t]he

                              - 29 -
statute requires a specific intent to do so, buttressing our

analysis.

             These offenses are also markedly different from the tax

fraud scheme in United States v. Marinello, on which our dissenting

colleague puts so much weight, in another key way.               Persons are

often able to skirt tax laws and go undetected for some time.

Indeed, by definition, a person who commits tax evasion attempts

to   conceal   his   acts   and    evade   detection.   United    States   v.

Stierhoff, 549 F.3d 19, 25 (1st Cir. 2008) (elements of tax evasion

include "an affirmative act of evasion or attempted evasion");

see, e.g., United States v. Marek, 548 F.3d 147, 150–51 (1st Cir.

2008) (defendant falsified invoices); United States v. Lavoie, 433

F.3d   95,     98-100   (1st      Cir.   2005)   (defendant   intentionally

underreported revenue).        An investigation of a tax offense would

not be in the offing upon the commission of the offense.                   By

contrast, consider murder, the underlying crime here.              Following

a homicide, more often than not the murder is reported, or a body

is found, or a person is reported missing.              A law enforcement

investigation is reasonably foreseeable.          Also consider robbery or

part of the sea visible from the shore that is very distant or
beyond anchoring ground."       Offing, The American Heritage
Dictionary of the English Language 1223 (5th ed. 2018); accord
offing, The New Oxford American Dictionary 1181 (2d ed. 2005)
("[T]he more distant part of the sea in view."). For this crime
and for any of the serious crimes that have actually triggered an
accessory-after-the-fact investigation in Massachusetts, the
investigation could be spotted on the horizon.

                                     - 30 -
extortion,       crimes   which   underlie    other    actual    Massachusetts

accessory-after-the-fact          prosecutions.       These   crimes   involve

immediate harm to a victim, unlike with tax crimes, where the

government must uncover an offense against the fisc.                   In such

situations, it is more likely that a law enforcement investigation

is in the offing.

            For the reasons stated above, it is clear that Silva's

Massachusetts accessory-after-the-fact conviction is an aggravated

felony under § 1101(a)(43)(S) because it is categorically "an

offense relating to obstruction of justice."20

            5.      The Dissent Misreads the BIA's Analysis

            There is no basis to conclude that we have adopted a

much looser nexus requirement than the BIA.                     Our dissenting

colleague overreads the BIA's analysis in Matter of Valenzuela

Gallardo to create a far tighter nexus requirement than the agency

did.

       20 We need not determine the precise boundaries of what
constitutes "an offense relating to obstruction of justice" under
§ 1101(a)(43)(S). Cf. Esquivel-Quintana, 137 S. Ct. at 1572. It
is enough that the various sources show that accessory after the
fact, as defined under the Massachusetts statute, clearly relates
to obstruction of justice for purposes of the INA. For that same
reason, Silva's argument that the statute is void for vagueness is
also meritless. See United States v. Zhen Zhou Wu, 711 F.3d 1, 16
(1st Cir. 2013) ("[W]e consider 'whether a statute is vague as
applied to the particular facts at issue,' for a defendant 'who
engages in some conduct that is clearly proscribed cannot complain
of the vagueness of the law as applied to the conduct of others.'"
(quoting Holder v. Humanitarian L. Project, 561 U.S. 1, 18-19
(2010)) (emphasis in original)).

                                     - 31 -
          The    BIA   held    that      generic    obstruction    of   justice

"cover[s] crimes involving (1) an affirmative and intentional

attempt (2) that is motivated by a specific intent (3) to interfere

with an investigation or proceeding that is ongoing, pending, or

'reasonably foreseeable by the defendant.'"             Matter of Valenzuela

Gallardo, 27 I. & N. Dec. at 456 (quoting Marinello, 138 S. Ct. at

1110); see also id. at 456 n.9.          The BIA identified three types of

investigations   covered      by   the   offense:    ongoing,     pending,   and

reasonably foreseeable.       But our dissenting colleague takes such

a narrow view of "reasonably foreseeable" that it essentially

merges into ongoing and pending investigations.            He errs, in part,

by interpreting the BIA's quotation of the reasonably foreseeable

language in Marinello to require an identical nexus in both the

statute at issue there, 26 U.S.C. § 7212(a), and the statute at

issue here, § 1101(a)(43)(S). The BIA, however, expressly rejected

that false equivalence, explaining that "Congress intended section

101(a)(43)(S) of the Act to apply more broadly than the provisions

at issue in . . . Marinello."         27 I. & N. Dec. at 454 n.6.21

     21   In our view, our dissenting colleague is also incorrect
when he argues that Chenery I requires us to interpret Marinello
identically to the BIA.    Dissenting Op. at 60-62; see SEC v.
Chenery Corp., 318 U.S. 80, 95 (1943). Chenery I "merely hold[s]
that an administrative order cannot be upheld unless the grounds
upon which the agency acted in exercising its powers were those
upon which its action can be sustained." 318 U.S. at 95. To be
sure we cannot substitute a new rationale when the agency
"misconceive[s] the law," id., but when the agency clearly states

                                    - 32 -
            To    confirm   that     the   dissent   misconstrues    the    BIA's

decision, we need look no further than the BIA implementation of

Matter of Valenzuela Gallardo.             In Matter of Cordero-Garcia, the

BIA held that the California offense of dissuading a witness is

categorically an offense related to obstruction of justice.                 27 I.

& N. 652, 653-54 (2019) (citing Cal. Penal Code § 136.1(b)(1)),

petition for review filed sub nom. Cordero-Garcia v. Garland, No.

19-72779 (9th Cir. argued Feb. 11, 2022).              The BIA held that the

statute's     specific      intent     requirement     implied     that    "    an

investigation or proceeding would necessarily be either ongoing,

pending, or reasonably foreseeable."                 Id. at 654.     "In other

words," it concluded, "there would be little reason for a person

to try to prevent or dissuade a victim or witness from reporting

the   crime      to   appropriate     authorities     unless     there    was   an

investigation in progress[,] or one was reasonably foreseeable."

its legal basis for acting, Chenery I does not require that we
follow the exact same interpretative path in sustaining the
agency's   actions,  see   H.J.   Friendly,  Chenery   Revisited:
Reflections on Reversal and Remand of Administrative Orders, 1969
Duke L.J. 199, 211.      The BIA determined that Massachusetts
accessory-after-the-fact is categorically an offense related to
obstruction of justice, that Silva was convicted of that offense,
and that he was therefore ineligible for withholding of removal.
We deny Silva's petition on the same grounds. To the extent that
we read the INA to authorize the BIA to act through a potentially
different pathway is of no moment.    To hold otherwise would be
perilous, with the Supreme Court indicating growing disfavor
towards deference to administrative agencies, see, e.g., Kisor v.
Wilkie, 139 S. Ct. 2400, 2424-2425 (Roberts, C.J., concurring);
id. at 2425-2449 (Gorsuch, J., dissenting).

                                      - 33 -
Id.    The BIA's interpretation of that California statute is on all

fours with our interpretation of the Massachusetts statute at issue

in this case.       It cannot, however, be squared with our dissenting

colleague's reading of the nexus requirement articulated in Matter

of    Valenzuela    Gallardo.      Nor   can   it   be   reconciled    with    our

dissenting colleague's mens rea\actus reus analysis, because like

Matter of Valenzuela Gallardo, Matter of Cordero-Garcia relies

solely on a specific intent requirement.

B.     Alternatively, If § 1101(a)(43)(S) Were Ambiguous, the BIA
       Would Prevail Under Chevron deference

               Assuming, arguendo, that the statute is ambiguous and

thus subject to Chevron deference,22 we must defer to the BIA's

interpretation.      See Scialabba v. Cuellar de Osorio, 573 U.S. 41,

56 (2014); Chevron, 467 U.S. at 844.

               Chevron deference applies where an agency has followed

suitably formal procedures, see United States v. Mead Corp., 533

U.S.    218,    229-30   (2001),    to   interpret       a   civil   statute    it

administers, see Gonzales v. Oregon, 546 U.S. 243, 265 (2006).                  In

applying Chevron, we follow a familiar two-step pathway.                  First,

we determine whether the statute is ambiguous.               Second, if it is,

we defer to the responsible agency's reasonable interpretation of

the ambiguous text.       See Chevron, 467 U.S. at 842-43.

       22 In light of Esqiuvel-Quintana, it is not clear which
interpretive approach we should employ, so we use both.

                                    - 34 -
               1.     At "Step Zero," the BIA's               Interpretation    Is
                      Eligible for Chevron Deference

               The BIA's administration of the INA falls within Mead's

safe harbor for formal adjudications.            See Mead, 533 U.S. at 226-

27; see also Negusie v. Holder, 555 U.S. 511, 517 (2009).                       Its

interpretation of § 1101(a)(43)(S) carries the force of law and

thus falls within Chevron's domain.             See Mead, 533 U.S. at 226-

27; see also T.W. Merrill & K.E. Hickman, Chevron's Domain, 89

Geo. L.J. 833 (2001).           Silva attempts to avoid that inexorable

conclusion, arguing that the decision in his case was unpublished

and thus not binding on future parties.           That contention, however,

looks     to    the     wrong   decision.       The     BIA    established      its

interpretation in a published decision issued by a three-member

panel in Matter of Valenzuela Gallardo.               See 27 I. & N. Dec. at

449.    Once the BIA formally interprets a statue, we may defer to

subsequent informal applications of the interpretation.                  Garcia-

Mendez v. Lynch, 788 F.3d 1058, 1061 (9th Cir. 2015) (citing

Neguise, 555 U.S. at 516).               To require each decision to be

published      by   a   three-member    panel   would    be    to   require    more

procedural safeguards than Congress intended.                    Cf. Vt. Yankee

Nuclear Power Corp. v. Nat. Res. Def. Council, 435 U.S. 519, 524

(1978).

               Additionally, Silva's contention that we cannot defer to

the BIA's interpretation of a statute with criminal implications

                                       - 35 -
is    misguided.     We     have    previously      deferred     to    the    BIA's

interpretation of the definition of aggravated felonies,23 see,

e.g., Soto-Hernandez v. Holder, 729 F.3d 1, 5 (1st Cir. 2013);

Lecky v. Holder, 723 F.3d 1, 5 (1st Cir. 2013), and continue to do

so here.24

             To hold otherwise would be flatly inconsistent with

precedents both of this Court and the Supreme Court.                   In Chevron

itself, the Supreme Court deferred to the EPA's interpretation of

the    Clean   Air   Act,    even     though    knowing       violation      of   an

implementation plan under that act carried criminal penalties.

See Guedes v. Bureau of Alcohol, Tobacco, Firearms & Explosives,

920 F.3d 1, 24 (D.C. Cir. 2019) (citing 42 U.S.C. § 7413(c)(1)

(1982)).       Similarly,    in     Babbitt    v.   Sweet     Home    Chapter     of

Communities    for   a   Great     Oregon,    the   Supreme    Court    expressly

considered the potential criminal penalties for a violation of the

Endangered Species Act and deferred to the Secretary of the

Interior's interpretation of that law.              515 U.S. 687, 702-704 &

704 n.18.      We regularly defer to interpretations of the IRS

Commissioner even though violating tax regulations can result in

      23  Silva and amici also argue that our previous decisions
did not expressly address his proposed "dual-application statute"
exception to Chevron. We now hold that no such exception exists.
     24   Our holding certainly does not run afoul of the Supreme
Court's observation in United States v. Appel that it has "never
held that the Government's reading of a criminal statutes is
entitled to any deference." 571 U.S. 359, 369 (2014).

                                     - 36 -
criminal penalties.      See, e.g., Dikow v. United States, 654 F.3d

144, 149-51 (1st Cir. 2011); see also United States v. O'Hagan,

521 U.S. 642, 647 (1997).        Indeed, regulatory offenses carrying

criminal penalties are legion in the Code of Federal Regulations,

see generally M. Chase, How to Become a Federal Criminal (2019),

but we continue to defer to agencies' interpretations of the

underlying statutes.

            2.   Assuming § 1101(a)(43)(S) Is Ambiguous, the BIA's
                 Interpretation of it Is Reasonable

            We explained earlier why interpreting § 1101(a)(43)(S)

to encompass Massachusetts accessory after the fact is reasonable.

See supra Part II.A. The BIA's understanding of the statute cannot

be said to be beyond the "bounds of reasonable interpretation."

Michigan v. EPA, 576 U.S. 743 (2015) (quoting Util. Air Regul.

Grp. v. EPA, 573 U.S. 302, 321 (2014)).

            In the realm of immigration, "Congressional powers are

at their apex and judicial powers are at their nadir."      Hernandez-

Lara v. Lyons, 10 F.4th 19, 54 (Lynch, J., dissenting).        Congress

has used that broad power to "charge[] the Attorney       General with

administering the INA."       Neguise, 555 U.S. at 516-17.       Thus,

"[j]udicial deference in the immigration context is of special

importance, for executive officials 'exercise especially sensitive

political    functions    that    implicate   questions   of   foreign

relations.'"     Id. at 517 (quoting INS v. Abudu, 485 U.S. 94, 110

                                  - 37 -
(1988)).     Compared to the executive, "[t]he judiciary is not well

positioned to shoulder primary responsibility for assessing the

. . .   diplomatic       repercussions"       of     sensitive       immigration

decisions.    INS v. Aguirre-Aguirre, 526 U.S. 415, 425 (1999); see

Griffiths v. INS, 243 F.3d 45, 49 (1st Cir. 2001).                    The BIA's

exercise of its Congressionally assigned functions certainly was

not unreasonable.

C.   The IJ and BIA Did Not Err in Determining That Silva's
     Massachusetts Accessory-After-the-Fact Conviction Was a
     "Particularly Serious Crime" for Purposes of Denying
     Withholding of Removal

             Silva   also   argues    that    even    if   his   Massachusetts

conviction is an aggravated felony under § 1101(a)(43)(S), it is

not a particularly serious crime that bars him from withholding of

removal.     The parties dispute whether the appropriate standard of

review of the BIA's particularly-serious-crime determination is de

novo or only for substantial evidence.               We need not decide this

issue because we conclude that there was no error under either

standard of review.

             Under Matter of N-A-M-, 24 I. & N. Dec. 336 (B.I.A.

2007), overruled in part on other grounds by Blandino-Medina v.

Holder, 712 F.3d 1338, 1347-48 (9th Cir. 2013), which Silva does

not challenge, the BIA "examine[s] the nature of the conviction,

the type of sentence imposed, and the circumstances and underlying

facts   of    the    conviction"     in   determining      whether    it   is   a

                                     - 38 -
particularly serious crime.       Id. at 342.      "[A]n offense is more

likely to be considered particularly serious if it is against a

person . . . ."   Matter of R-A-M-, 25 I. & N. Dec. 657, 662 (B.I.A.

2012) (citing Matter of N-A-M-, 24 I. & N. Dec. at 343).              And

factual   findings   made   by   the   BIA   in   determining   whether   a

conviction is for "a particularly serious crime" are "conclusive

unless any reasonable adjudicator would be compelled to conclude

to the contrary," which "is a 'highly deferential' standard."

Garland v. Ming Dai, 141 S. Ct. 1669, 1674, 1677 (2021) (first

quoting 8 U.S.C. § 1252(b)(4)(B); and then quoting Nasrallah v.

Barr, 140 S. Ct. 1683, 1692 (2020)).

           The record supports the BIA's determination that, based

on his guilty plea to the Massachusetts indictment, Silva admitted

to knowing that the individuals whom he assisted had committed a

murder.   Based on that finding and Silva's conduct in aiding known

murderers to avoid or escape apprehension and punishment, the BIA

did not commit any legal or other error in determining that the

accessory-after-the-fact conviction was a particularly serious

crime which rendered him ineligible for withholding of removal.

                                  III.

           Silva's petition for review of the BIA's final order of

removal is denied.

                     -DISSENTING OPINION FOLLOWS-

                                 - 39 -
              BARRON, Circuit Judge, dissenting. Is the crime of being

an accessory after the fact to a "felony" under Massachusetts law,

see   Mass.     Gen.   Laws       ch.   274,    § 4,   an     "offense   relating    to

obstruction of justice" under the Immigration and Nationality Act

("INA"),    8   U.S.C.       § 1101(a)(43)(S),         such    that   this   state-law

accessorial crime constitutes an "aggravated felony" and thus

makes the lawful permanent resident convicted of committing it

removable and ineligible for asylum, see 8 U.S.C. §§ 1158(b)(2),

1227(a)(2)(A)(iii)?              In concluding in this case that this state-

law accessorial crime is "an offense relating to obstruction of

justice"      under        § 1101(a)(43)(S),       the      majority     rejects    the

reasoning of the Third Circuit in Flores v. Attorney General, 856

F.3d 280 (3d Cir. 2017), and the Ninth Circuit in Valenzuela

Gallardo v. Barr (Valenzuela Gallardo IV), 968 F.3d 1053 (9th Cir.

2020).     But, even accepting that the majority is right to reject

the reasoning of those courts, it is wrong to uphold the ruling of

the Board of Immigration Appeals ("BIA") that the Massachusetts

accessory-after-the-fact offense of which Carlos Monteiro Silva

was   convicted       is    an    "obstruction    of     justice"-related      offense

within the meaning of § 1101(a)(43)(S).

                                           I.

              It helps first to explain exactly how the majority's

construction of § 1101(a)(43)(S) differs from that of the Third

Circuit in Flores and the Ninth Circuit in Valenzuela Gallardo IV.

                                         - 40 -
Each of those cases rejected the construction of the phrase "an

offense relating to obstruction of justice" in § 1101(a)(43)(S)

that   the   BIA   had    adopted   in    Matter      of    Valenzuela    Gallardo

(Valenzuela Gallardo III), 27 I. & N. Dec. 449 (BIA 2018).

             The Third and Ninth Circuits held that the "obstruction

of justice"-related offense referred to in that federal statute

requires proof of a much tighter nexus than the BIA in Valenzuela

Gallardo III had held that the offense requires between an official

investigation      or    proceeding       and   the        obstructive    conduct.

Specifically, those courts held that the required nexus needs to

be between the obstructive conduct and an official investigation

or proceeding that, at the time of that conduct, was at least

pending   and   not,     for   example,    merely     reasonably    foreseeable.

Valenzuela Gallardo IV, 968 F.3d at 1068; Flores, 856 F.3d at 292-

294.

             Moreover, on that basis, the Third and Ninth Circuits

rejected the BIA's determination in each of the cases before them

that an accessory after the fact offense that did not require proof

of such a tight nexus could be "an offense relating to obstruction

of justice" within the meaning of § 1101(a)(43)(S).                      Valenzuela

Gallardo IV, 968 F.3d at 1069; Flores, 856 F.3d at 293-96.                    And,

the Third and Ninth Circuits further held, persuasively in my view,

that the words "relating to" in § 1101(a)(43)(S) -- though words

of inclusion -- do not bring within the scope of the offense

                                    - 41 -
referred to in that provision an offense that is not itself an

"obstruction of justice" offense at all.         Valenzuela Gallardo IV,

968 F.3d at 1068; Flores, 856 F.3d at 290-91, 296.

          In   Silva's   case,   the   BIA   embraced   the   same   looser

description of the nexus requirement that the BIA had embraced in

Valenzuela Gallardo III and that the Third and Ninth Circuits

rejected for not being tight enough.         The BIA then ruled based on

that understanding of the nexus requirement that Silva's state-

law accessorial offense is an "offense relating to obstruction of

justice" under § 1101(a)(43)(S).

          Silva now contends that we must reject the BIA's ruling

in his case for essentially the reasons that Flores and Valenzuela

Gallardo IV gave in ruling as they did in those cases.         But, Silva

does not ask us to overturn the BIA's ruling only by asking us to

endorse the tighter nexus that the Third and Ninth Circuits

described.   He also contends, as a fallback argument, that even if

we were to accept that the BIA has correctly described the nexus

requirement to be looser than the Third and Ninth Circuits held it

to be, the Massachusetts accessory-after-the-fact offense of which

he was convicted would not be an "offense relating to obstruction

of justice" under § 1101(a)(43)(S) because the least of the conduct

that this accessorial offense criminalizes would still not be

encompassed by that generic, federal "obstruction of justice"-

                                 - 42 -
related offense.     See Moncrieffe v. Holder, 569 U.S. 184, 190-91

(2013).

          As    I   will    explain,      Silva's    fallback     argument   for

granting his petition for review is a winning one.                     For that

reason, the majority's holding that the BIA's construction of the

nexus requirement for "an offense relating to obstruction of

justice" is a reasonable one under Chevron, U.S.A., Inc. v. Natural

Resources Defense Council, Inc., 467 U.S. 837 (1984), provides no

basis for me to conclude otherwise.          In that holding, the majority

just endorses -- after drawing on the approach for interpreting

§ 1101(a)(43)     that    the   Supreme    Court    set   forth   in   Esquivel-

Quintana v. Sessions, 137 S. Ct. 1562 (2017) -- the reasonableness

of   construing     the    "obstruction      of    justice"-related     offense

referred to in § 1101(a)(43)(S) to be constrained only by a nexus

requirement that is as loose as the one that the BIA has described.

For, as Silva persuasively contends, the BIA's construction of "an

offense relating to obstruction of justice" -- given the looseness

of that construction's understanding of the nexus requirement --

still defines that offense to encompass more conduct than the least

of the conduct that Silva's accessorial offense of conviction

encompasses.

          But, I emphasize, I also can see no reason to reject

Silva's fallback argument insofar as the majority independently

means to hold -- again pursuant to Esquivel-Quintana but this time

                                    - 43 -
without purporting to afford any deference under Chevron -- that

the generic, federal "obstruction of justice"-related offense to

which § 1101(a)(43)(S) refers is not constrained by any nexus

requirement at all.    For, under SEC v. Chenery Corp., 318 U.S. 80,

94 (1943), we cannot sustain the BIA's ruling in Silva's case based

on such a nexus-less construction of that offense unless we are

bound to adopt that construction to the exclusion of the nexus-

based one that the BIA has set forth and that the majority itself

agrees is reasonable.    And, as I will explain, the majority offers

no persuasive reason to conclude that a nexus-less construction

must be adopted over the nexus-based one that the BIA has set

forth.

                                 II.

            Before turning to the majority's independent holding

endorsing a nexus-less construction of the offense referred to in

§ 1101(a)(43)(S), it makes sense to start with the majority's more

modest one.    True, the majority concludes in that holding that the

offense requires some such nexus to be shown and that the BIA's

operative description of that nexus requirement is a reasonable

one.     But, as I will explain, that holding provides no basis for

rejecting Silva's petition for review, despite being nexus-based.

To show why, it is necessary, as an initial matter, to explain in

more detail just what the BIA's operative understanding of that

nexus requirement is.    I thus now turn to that task.

                                - 44 -
                                    A.

            In Valenzuela Gallardo III, the BIA was attempting to

address a Ninth Circuit ruling that had rejected a prior BIA

construction of § 1101(a)(43)(S).         See 27 I. & N. Dec. at 451-52.

The Ninth Circuit had held that the BIA's earlier construction

rendered the "obstruction of justice"-related offense to which

§ 1101(a)(43)(S) refers too vague.             See Valenzuela Gallardo v.

Lynch (Valenzuela Gallardo II), 818 F.3d 808, 812, 824 (9th Cir.

2016),   vacating   and   remanding    Matter     of   Valenzuela    Gallardo

(Valenzuela Gallardo I), 25 I. & N. 838 (BIA 2012).           That was so,

the Ninth Circuit explained, because that construction did not

require as an element of that offense any nexus between the

defendant's obstructive conduct and an official investigation or

proceeding and so left unclear the kind of conduct that would

qualify as obstructive.     Id.

            To address that concern, the BIA explained in Valenzuela

Gallardo III that, in accord with Esquivel-Quintana, it would draw

its   revised   understanding     of     the    offense   referred    to   in

§ 1101(a)(43)(S) from "Federal and State law, Federal sentencing

guidelines, the Model Penal Code, and scholarly commentary."               27

I. & N. Dec. at 452-53 (citing Esquivel-Quintana, 137 S. Ct. at

1570-72).    The BIA then focused heavily, though not exclusively,

on the offenses set forth in Chapter 73 of the federal criminal

code, which is entitled "Obstruction of Justice."           Id. at 453-56.

                                  - 45 -
           In canvassing those materials, the BIA in Valenzuela

Gallardo III acknowledged that most of the offenses in Chapter 73

contained a quite tight nexus requirement; the provisions in that

chapter that set forth those offenses made clear that they could

be committed only if the defendant obstructed an investigation or

proceeding that was in fact pending.         Id. at 454.    But, the BIA

also noted that the "Obstruction of Justice" offense set forth in

18 U.S.C. § 1512 was different.       Id.

           At the time that § 1101(a)(43)(S) was enacted, the BIA

pointed out, § 1512 provided in relevant part that it was a crime

knowingly to use "intimidation, physical force, threats, corrupt

persuasion, or misleading conduct toward another person with the

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.'"    Id. (emphasis omitted) (quoting 18 U.S.C.

§ 1512(b) (1994)).    The BIA then also explained that the Supreme

Court in Marinello v. United States, 138 S. Ct. 1101 (2018), had

offered a "synthesi[s]" of the cases that had construed § 1512's

nexus requirement and that the Court in Marinello had relied on

that body of precedent to define the nexus required under the

Internal Revenue Code provision that was there at issue, which

made it a crime to interfere with investigations into tax crimes,

see 26 U.S.C. § 7212(a).      27 I. & N. Dec. at 455.

                                   - 46 -
              The BIA explained that, in setting forth the synthesis

of    the    case   law      that   concerned        § 1512's      nexus   requirement,

Marinello made clear that § 1512 required proof of a nexus between

the defendant's obstructive conduct and an official investigation

that was merely "'reasonably foreseeable by the defendant' at the

time of the obstructive conduct" rather than pending as of that

time.       Valenzuela Gallardo III, 27 I. & N. Dec. at 455 (quoting

Marinello, 138 S. Ct. at 1110).                      The BIA also explained that

Congress       would        have    been    aware         of     that    Marinello-based

understanding          of     § 1512's      nexus         requirement      in     enacting

§ 1101(a)(43)(S).           Id. at 455-56.          Based on that conclusion about

what    Congress     would     have    known,       the    BIA    then   relied    on   the

Marinello-based understanding of the required nexus in § 1512 to

define "an offense relating to obstruction of justice" in a way

that encompassed obstructive conduct so long as it was connected

to "reasonably foreseeable" proceedings or investigations.

              It is thus clear that Valenzuela Gallardo III was relying

on    Marinello's      understanding          of    the    "reasonably     foreseeable"

standard for defining the required nexus to address the vagueness

concern that had led the Ninth Circuit to reject the BIA's prior

nexus-less construction of § 1101(a)(43)(S).                      And, that is notable

for     present     purposes        because        Marinello      explained     that    the

"reasonably foreseeable" standard, though more expansive than a

                                           - 47 -
pending-investigation-or-proceeding standard such as the Third and

Ninth Circuits had embraced, is still importantly constrained.

           Specifically, the Court in Marinello made a point of

explaining   that    to      demonstrate      that    a    "proceeding"        or

"investigation" was "reasonably foreseeable" at the time of the

obstructive conduct, "[i]t is not enough for the Government to

claim that the defendant knew [law enforcement] may catch on to

his unlawful scheme eventually.         To use a maritime analogy, the

proceeding must at least be in the offing."           Marinello, 138 S. Ct.

at 1110. Thus, Marinello clearly rejected the notion that evidence

that a defendant had engaged in a tax scheme that was unlawful

could suffice in and of itself to prove that the "reasonably

foreseeable"-based    nexus    requirement     had    been      met   under   the

federal tax crime there at issue for "obstruct[ing] or imped[ing]

. . . the due administration" of Title 26.           See id. (discussing 26

U.S.C. § 7212(a)).

           Indeed, were that not so, the Court could have just said

that proof of the defendant's predicate unlawful tax scheme would

suffice to satisfy that nexus requirement for the offense defined

in 26 U.S.C. § 7212 rather than that proof that law enforcement

"may catch on to" that scheme "eventually" would not be enough to

satisfy that requirement.       After all, proof of the existence of

the   predicate   unlawful    tax   scheme,    in    and   of   itself,   would

necessarily constitute proof that at least such a mere eventuality

                                    - 48 -
was possible.    And, indeed, our own precedent accords with this

same understanding of the narrowing import of Marinello's "in the

offing" gloss on the "reasonably foreseeable" standard that the

Court there described as constraining the nexus requirement not

only for the offense at issue in that case but also for those like

it, such as the one set forth in § 1512.             See United States v.

Takesian, 945 F.3d 553, 566-67 (1st Cir. 2019) (concluding a

proceeding was reasonably foreseeable to the defendant under the

Marinello standard because he knew that "the [Internal Revenue

Service] was investigating the money trail that could lead to him"

and because he testified that "he believed investigators put the

screws on him").25

           There is, of course, a separate question regarding the

element   or   elements   of   the    "obstruction   of   justice"-related

offense referred to in § 1101(a)(43)(S) that the BIA understood to

be constrained by the nexus requirement to which this "reasonably

     25The majority notes that the phrase "in the offing" "refers,
in the maritime sense, to '[t]he part of the sea visible from the
shore that is very distant or beyond anchoring ground.'" Maj. Op.
at 29 n.19 (quoting Offing, The American Heritage Dictionary of
the English Language 1223 (5th ed. 2018)). The majority emphasizes
the "very distant" portion of this definition; to me, the most
important part for present purposes is the "visible" part. But,
we need not parse the dictionary entry too finely because Marinello
makes clear that it used the phrase "in the offing" to establish
that the government has not proven an investigation to have been
"reasonably foreseeable" when all it has shown is that "the
defendant knew [law enforcement] may catch on to his unlawful
scheme eventually," 138 S. Ct. at 1110.

                                     - 49 -
foreseeable" standard applies. I have thus far described the nexus

requirement as if it constrains the elements of that offense that

define its actus reus and not merely its mens rea.         And, that is

for good reason.

           The BIA, after having canvassed Chapter 73, Marinello,

and other aspects of federal and state law, as well as other

materials, expressly laid out the elements of the "obstruction of

justice"-related offense in § 1101(a)(43)(S) as follows: "(1) an

affirmative and intentional attempt (2) that is motivated by a

specific   intent   (3)   to   interfere   with   an   investigation   or

proceeding that is ongoing, pending, or 'reasonably foreseeable by

the defendant.'"    Valenzuela Gallardo III, 27 I. & N. Dec. at 460

(emphasis added).    Given the BIA's use of the word "attempt" in

"(1)," and the word "is" in "(3)," the BIA must be read here to be

describing the nexus requirement as a constraint on -- at least --

the scope of the offense's actus reus and not only on its mens

rea.26

     26 Nor should we be surprised that the BIA in Valenzuela
Gallardo III chose to treat the "reasonably foreseeable" standard
as a constraint that limited -- at least -- the actus reus of the
generic, federal "obstruction of justice"-related offense. As we
have seen, the BIA there was borrowing the "reasonably foreseeable"
standard from the one that the Court had announced in Marinello.
And, Marinello clearly treated that standard as if it were a
constraint on the actus reus of the offense there at issue rather
than only on the offense's mens rea. Specifically, in articulating
the "reasonably foreseeable" constraint on the scope of the offense
set forth in § 7212 of Title 26, Marinello focused its interpretive

                                 - 50 -
              As a result, I understand the BIA in Valenzuela Gallardo

III to describe the offense referred to in § 1101(a)(43)(S) as one

that requires proof of a nexus between the obstructive conduct and

an    investigation    or     proceeding      that    is    in   fact   reasonably

foreseeable at the time of that conduct.                   I thus understand the

BIA to describe that offense in a manner that is at odds with the

notion that proof that the defendant merely believed at that time

(even    if    mistakenly)     that     an    investigation      was    reasonably

foreseeable could be enough.

              That said, I am aware that the BIA in Valenzuela Gallardo

III     did   assert   that    Congress       intended      § 1101(a)(43)(S)    to

encompass both the federal accessory-after-the-fact offense, 18

U.S.C. § 3, and the California accessory-after-the-fact offense at

issue in that case, too.            27 I. & N. Dec. at 459, 461 & n.17.          I

am also aware that the BIA in that case explained that each of

these accessorial offenses is encompassed by § 1101(a)(43)(S)

because of its mens rea element -- in the case of the federal one,

the    specific    intent     "to    hinder     or   prevent     [an    offender's]

lens on the phrases "obstructs or impedes" and "due administration"
in that statute.    138 S. Ct. at 1106.     Each of those phrases
concerns the actus reus of the offense that the statute sets forth.
By contrast, the consensus among lower courts at the time was that
"the statute's mens rea requirement" was embodied in the word
"corruptly" in that statute, United States v. Miner, 774 F.3d 336,
347 (6th Cir. 2014) (collecting cases); see also United States v.

that was not at issue in Marinello.

apprehension, trial or punishment," 18 U.S.C. § 3, and in the case

of the California one, the specific intent "to interfere either in

an ongoing, pending, or reasonably foreseeable investigation or

proceeding," 27 I. & N. Dec. at 461.             Finally, I am aware that in

theory such an intent could be proved without there being proof

that any such investigation or proceeding was in fact reasonably

foreseeable at the time of the defendant's accessorial conduct.

See People v. Rizo, 996 P.2d 27, 30-31 (Cal. 2000) (holding that

"a specific intent crime" that "focuses solely on the acts and

intent of the violator" may be committed even if the defendant's

intent is based on a mistaken understanding).

           Nonetheless,     as     I    have    explained,    the   BIA,     after

completing    its    analysis     of    § 1101(a)(43)(S)      in    accord    with

Esquivel-Quintana, quite clearly described the actus reus of the

offense to be "an affirmative and intentional attempt . . . to

interfere with an investigation or proceeding that is ongoing,

pending,     or     'reasonably        foreseeable   by      the    defendant.'"

Valenzuela Gallardo III, 27 I. & N. Dec. at 460 (emphasis added).

And, the government in its briefing to us cites to that same

description in describing the BIA's understanding of the nexus

requirement just as I have.            Thus, in light of the BIA's express

description of the elements of the offense in § 1101(a)(43)(S), I

see no basis for concluding that the BIA has set forth a reasoned

basis for construing that offense's actus reus to be unconstrained

                                       - 52 -
by the "reasonably foreseeable"-based nexus requirement.       Cf.

Pugin v. Garland, 19 F.4th 437, 450 (4th Cir. 2021) (noting that

courts "give no deference to the Board's construction of state law

or determination of its fit with federal law," despite the court's

finding that deference was due to the BIA's interpretation of

§ 1101(a)(43)(S)); Higgins v. Holder, 677 F.3d 97, 109 (2d Cir.

2012) (Katzmann, J., concurring) (same).27

     27 In the same "Application" section of Valenzuela Gallardo
III in which the BIA discussed the California statute, it explained
that the    Marinello-informed, "reasonably foreseeable"-based
construction of the nexus requirement for the actus reus of "an
offense relating to obstruction of justice" that it was adopting
was "consistent with [its] prior holdings." Valenzuela Gallardo
III, 27 I. & N. Dec. at 460. It then pointed to cases in which it
had held that although the offense set forth by the federal
accessory-after-the-fact statute, 18 U.S.C. § 3, is an "offense
relating to obstruction of justice" under the INA, the offense set
forth in the federal misprision of felony statute, id. § 4, is
not.   Valenzuela Gallardo III, 27 I. & N. Dec. at 460 (citing
Matter of Espinoza-Gonzalez, 22 I. & N. Dec. 889, 894 (BIA 1999)
and In re Batista-Hernandez, 21 I. & N. Dec. 955, 962 (BIA 1997)).
And, the BIA did so with reference to the specific intent element
of the federal accessory-after-the-fact offense. Id. at 461. But,
Valenzuela Gallardo III did not explain in discussing Espinoza --
which pre-dated Marinello itself -- how an element of an
accessorial offense that requires proof of merely a purpose to
interfere with an investigation in and of itself could suffice to
make an offense one "relating to obstruction of justice," given
Valenzuela Gallardo III's Marinello-based rationale for expressly
holding that Congress must be understood to have intended the actus
reus of an offense "relating to obstruction of justice" to require
proof of a nexus between the obstructive conduct and a reasonably
foreseeable investigation or proceeding. I thus also see no basis
for concluding from Valenzuela Gallardo III's discussion of
Espinoza that Valenzuela Gallardo III's Marinello-informed, actus
reus-based definition of the nexus requirement is not the operative
one.   Nor does the government suggest otherwise, given that it
describes the BIA's operative understanding of the elements of the

                              - 53 -
                                      B.

            There is one hanging thread.         The majority asserts that

it is wrong to read the BIA as "requir[ing] an identical nexus in

both the statute at issue [in Marinello], 26 U.S.C. § 7212, and

the statute at issue here, § 1101(a)(43)(S)."               Maj. Op. at 32.

            In support of this assertion, the majority first points

to a statement by the BIA in Valenzuela Gallardo III in which it

supposedly "expressly rejected that false equivalence."                 Id.   The

statement from Valenzuela Gallardo III that the majority has in

mind is the one in which the BIA observes that Congress intended

§ 1101(a)(43)(S) "to apply more broadly than" 26 U.S.C. § 7212 and

18 U.S.C. § 1503, the section of Chapter 73 that defines the

"catch-all" "obstruction of justice" offense.                 Maj. Op. at 32

(quoting Valenzuela Gallardo III, 27 I. & N. Dec. at 454 n.6).

            But, a closer examination of the BIA's decision reveals

that the purported "express[] reject[ion]" that statement makes

has nothing to do with the scope of the nexus requirement for "an

offense     relating      to       obstruction        of     justice"     under

§ 1101(a)(43)(S).      Read in context, the footnoted statement aims

only   to   make    the   simple    point    that     the   generic,    federal

"obstruction   of    justice"-related       offense    that    Congress   there

referred to encompasses crimes other than the two specific federal

actus reus of the "obstruction of justice"-related                      offense
referred to it § 1101(a)(43)(S) just as I do.

                                    - 54 -
offenses set forth respectively in 18 U.S.C. § 1503 and 26 U.S.C.

§ 7212 -- as it plainly does.          See Valenzuela Gallardo III, 27 I.

& N. Dec. at 454 & n.6.         The footnoted statement thus clarifies

that § 1101(a)(43)(S) is referring to a crime that encompasses

even, for example, state-law crimes that criminalize the same swath

of conduct as the generic, federal "obstruction of justice" offense

to which § 1101(a)(43)(S) refers.

            In performing that clarifying function, the footnoted

statement in no way purports to be defining anew the scope of the

nexus    requirement     for   the   generic,      federal    "obstruction       of

justice"-related    offense     or     the    meaning    of   the   "reasonably

foreseeable" standard that constrains the nexus requirement of

that offense's actus reus.       The BIA in the main body of its opinion

relied   heavily   on    Marinello,     as    I   have   described,      and   then

expressly cited Marinello and United States v. Aguilar, 515 U.S.

593 (1995), which construed the nexus requirement in § 1503, see

id. at 599-600, when it set forth the elements of "an offense

relating to obstruction of justice," see Valenzuela Gallardo III,

27 I. & N. Dec. at 456.        It would be strange for the BIA to then

redefine   a   portion    of   those   elements     in   a    footnote    without

addressing why.

            The majority also points to a BIA case decided after

Valenzuela Gallardo III that, the majority contends, demonstrates

that the BIA did not intend to rely on Marinello to define the

                                     - 55 -
actus reus of "an offense relating to obstruction of justice."

Maj. Op. at 33-34 (discussing Matter of Cordero-Garcia, 27 I. & N.

Dec. 652 (BIA 2019)).      But, the BIA there did not purport to reject

its earlier clear statement of the actus reus of the offense as

being subject to a "reasonably foreseeable" standard.              Nor do I

read   the    BIA   in   Cordero-Garcia   to    have   suggested   that   the

"reasonably foreseeable" standard that constrains the actus reus

of "an offense relating to obstruction of justice" is not itself

constrained by the "in the offing" gloss that Marinello placed on

it.    Rather, I read Cordero-Garcia to have accepted Valenzuela

Gallardo III's description of the actus reus of that offense as

being subject to such a "reasonably foreseeable"-constrained --

and Marinello-informed -- nexus requirement and then to have

concluded that, even still, the state law offense at issue there

qualified as "an offense relating to obstruction of justice" under

§ 1101(a)(43)(S).        See Cordero-Garcia, 27 I. & N. Dec. at 654

(relying on the "specific intent" element of a California criminal

offense to find that the offense was a categorical match to the

generic, federal offense set out in § 1101(a)(43)(S)).

             In other words, I read Cordero-Garcia to be no different

from Valenzuela Gallardo III or the BIA decision in Silva's case.

It, too, embraces an understanding of the actus reus of "an offense

relating     to   obstruction   of   justice"   that   is   nexus-based   and

constrained by the reasonably foreseeable standard that Marinello

                                     - 56 -
sets   forth.       And,    it,   too,    does    so   notwithstanding      that   it

concludes    that    a     state-law      accessorial      offense    is   such    an

"obstruction of justice"-related offense even though that state-

law accessorial offense has no similarly constrained actus reus.

I also emphasize that, in concluding that the BIA has not yet

backed away from Valenzuela Gallardo III's quite clear description

of the offense's actus reus, I am taking a position that the

government      itself     appears   to    share,      given   the   way   that    the

government's briefing to us describes the understanding of actus

reus of the offense that the BIA embraced in Valenzuela Gallardo

III and re-embraced yet again in the case before us.

                                          III.

            With the BIA's operative understanding of the nexus

requirement for "an offense relating to obstruction of justice"

now in view, I am almost ready to address whether Silva's offense

of conviction is such an offense.                 But, before taking up that

question -- which, as I will explain, is the dispositive one in

this case -- there remains one more task to complete.                  It concerns

the majority's independent, Chevron-free holding that I mentioned

at the outset.

            In that holding, the majority appears to conclude that,

insofar as we are not bound to defer under Chevron to the BIA's

nexus-based      construction        of     the     offense     referred     to     in

§ 1101(a)(43)(S), that offense may reasonably be construed under

                                         - 57 -
the interpretive approach set forth in Esquivel-Quintana not to be

subject to a nexus requirement at all.        And, the majority then

appears to go on to conclude in that holding that Silva's petition

must be rejected for this reason, too.

           But, notably, the majority does not explain in so holding

what basis there is for not applying Chevron here.         It does not

suggest, for example, that the BIA's nexus-based construction of

the   "obstruction   of   justice"-related   offense   referred   to   in

§ 1101(a)(43)(S) is an unreasonable one, such that the BIA's

construction would not be entitled to deference for that reason.

In fact, the majority holds the opposite.

           Nor does the majority suggest that Chevron deference is

not available to the interpretive question at hand, even if the

BIA's construction is a reasonable one.         Rather, the majority

rejects each of Silva's arguments to that effect as well as those

of the amici and even explains why our precedents leave us, as a

panel, with no basis for rejecting Chevron's application to the

extent that the BIA's nexus-based construction is a reasonable

one.28

       I note in this regard that I agree with the majority that
      28

there is no basis for this panel to hold that Chevron has no
application at all, given that we have three times before upheld
BIA constructions of other provisions of this same part of the INA
under Chevron. See De Lima v. Sessions, 867 F.3d 260, 264-65 (1st
Cir. 2017); Soto-Hernandez v. Holder, 729 F.3d 1, 3-5 (1st Cir.
2013); Lecky v. Holder, 723 F.3d 1, 5 (1st Cir. 2013). I also

                                - 58 -
          There is, though, still one more problem with holding

that Silva's petition must be rejected under Esquivel-Quintana

based on a nexus-less construction of the "obstruction of justice"-

related offense referred to in § 1101(a)(43)(S). And, that problem

stems from the fact that the majority does not explain at any point

how, insofar as Chevron somehow does not apply here, the Esquivel-

Quintana factors favor the adoption of a nexus-less construction

of that offense to the exclusion of the nexus-based one that the

BIA describes.

          The majority does, in applying those factors, advance

reasons to reject the strict, pending-investigation-or-proceeding

nexus requirement that the Third and Ninth Circuits have adopted.29

emphasize, as the majority does as well, that the BIA here is not
construing a provision of the federal criminal code.         It is
construing a provision of the INA that determines the type of
predicate offense that makes a lawful permanent resident removable
and disqualifies a noncitizen from being eligible for asylum.
     29 I note in this regard that the majority invokes a series

of dictionary definitions to support its contention that the Third
and Ninth Circuits are wrong to hold that "an offense relating to
obstruction of justice" requires proof of a nexus between
obstructive conduct and an investigation or proceeding that, at
the time of that conduct, is at least pending. But, even if those
definitions support that conclusion, they do not themselves
support a no-nexus understanding of the actus reus of "an offense
relating to obstruction of justice." And, in fact, the majority
does not attempt to explain how those definitions do.       Nor, I
should add, do any of the provisions in Chapter 73 to which the
majority refers provide support for a non-nexus understanding, as
one of the two that the BIA might be read to suggest does so is 18
U.S.C. § 1512 itself while the other one is expressly restricted
to conduct committed "with the intent to facilitate an illegal
gambling business," 18 U.S.C. § 1511(a) (1996).

                              - 59 -
And, I suppose, the majority could be understood in doing so also

to be offering reasons that could explain why such a nexus-less

construction is itself a permissible one.   I suppose as well that,

     The majority does identify some state law criminal codes that
have grouped disparate offenses, some of which lack a nexus
requirement, within a chapter or section and given the entire
assortment the label of "obstruction of justice" or something
similar.   But, the majority understandably does not go on to
suggest on that basis that § 1101(a)(43)(S) is better read -- let
alone best read even if the BIA reads the relevant materials
otherwise -- to be referring to a nexus-less "obstruction of
justice" offense. Cf. Jerome v. United States, 318 U.S. 101, 104
(1943) ("[W]e must generally assume, in the absence of a plain
indication to the contrary, that Congress when it enacts a statute
is not making the application of the federal act dependent on state
law.").
     The majority also points to the fact that the Model Penal
Code identifies an accessory after the fact offense as "an
independent offense of obstruction of justice." Maj. Op. at 26
(quoting Model Penal Code § 242.1 explanatory note (Am. L. Inst.
1985) [hereinafter MPC]). But, the majority does not hold that
the only reasonable construction of § 1101(a)(43)(S) is one that
tracks that understanding. That may be because the Model Penal
Code did not even contain an offense labeled "obstruction of
justice" at the time that § 1101(a)(43)(S) was enacted, see MPC
§§ 242.1-.8, and because the Model Penal Code itself acknowledges
that, under the "traditional concept" of "common law . . .
accessory after the fact," a crime of that type was not "an
independent offense of obstruction of justice," id. § 242.1
explanatory note. Thus, here, too, the majority fails to offer a
basis for favoring a nexus-less construction over the BIA's nexus-
based one.
     Finally, although the majority relies on some precedent to
assert that the federal accessory-after-the-fact statute, 18
U.S.C. § 3, has a "gist" of "essentially . . . obstructing
justice," Maj. Op. at 18, it does not explain why one may conclude
from that precedent alone that such a nexus-less construction is
to be preferred to the BIA's nexus-based construction of the actus
reus of "an offense relating to obstruction of justice." I also
note in that regard that Congress itself saw fit to put that
accessory-after-the-fact statute in a chapter other than Chapter
73, which is the only chapter on which Congress chose to bestow
the title, "Obstruction of Justice."

                              - 60 -
if we are not permitted to afford Chevron deference to the BIA's

nexus-based construction despite its reasonableness, then we must

adopt the nexus-less construction if it is superior to the BIA's.

See H.J. Friendly, Chenery Revisited: Reflections on Reversal and

Remand of Administrative Orders, 1969 Duke L.J. 199, 210.

           But, in light of Chenery, to justify the rejection of

Silva's   petition     based     on   a     nexus-less      construction    of    the

"obstruction     of     justice"-related            offense    referred     to     in

§ 1101(a)(43)(S), the majority must do more than explain merely

why that nexus-less construction is as permissible as the nexus-

based one that the BIA describes.                   For, without a reason to

conclude that the nexus-less construction is superior, there is no

reason to conclude that the nexus-based construction that the BIA

has adopted and that it relied on in Silva's case is not a

permissible one for it to have applied.                Yet, the majority at no

point explains why (nor, for that matter, does the government) the

nexus-less rather than the nexus-based construction is the one

that the BIA would be bound to apply insofar as Chevron is not

applicable.

           Thus,      because    I    see     no    basis     under   Chenery     for

attributing     to     the   BIA      the     nexus-less       understanding       of

§ 1101(a)(43)(S) to which the majority adverts, I also see no basis

for   denying    Silva's        petition      for     review     based     on    that

understanding.       And so, unless the BIA's own understanding of the

                                      - 61 -
nexus requirement for the "obstruction of justice"-related offense

to which that provision refers encompasses the accessorial offense

that Silva was convicted of under Massachusetts law, his petition

must be granted.     All of which is to say that -- at last -- I can

now move on to an assessment of the portion of the majority's

opinion in which it holds pursuant to the BIA's nexus-based

construction    of   the   "obstruction    of   justice"-related   offense

referred to in § 1101(a)(43)(S) that Silva's conviction for being

an accessory after the fact under Massachusetts law is an offense

of that kind.

                                   IV.

          The majority draws in this portion of its opinion on the

approach -- commonly referred to as the "categorical approach" --

that the Court relied on in Moncrieffe to construe § 1101(a)(43).

See 569 U.S. at 190-91. Under that approach, the critical question

is whether a comparison of the elements of the generic, federal

"obstruction    of    justice"-related      offense    referred    to   in

§ 1101(a)(43)(S) and the elements of the state-law accessorial

offense of which Silva was convicted reveals that the least of the

conduct criminalized by that accessorial offense is encompassed by

the generic, federal offense. For, under the categorical approach,

unless that comparison does reveal such a match arising from the

elements of the two offenses, Silva's accessorial offense of

conviction is not "an offense relating to obstruction of justice."

                                  - 62 -
           I have explained how the BIA defines the elements of the

"offense   relating    to   obstruction    of   justice"     to   which

§ 1101(a)(43)(S) refers.     There remains to address, then, only

whether that offense -- so understood -- encompasses the least of

the conduct encompassed by the elements of the Massachusetts

accessory-after-the-fact offense of which Silva was convicted.

           That accessorial offense contains the following four

elements: that the defendant (1) "harbors, conceals, maintains, or

assists the principal felon or accessory before the fact, or gives

such offender any other aid," (2) does so "after the commission of

a felony," (3) does so "knowing that [the person being assisted]

has committed a felony or has been accessory thereto before the

fact," and (4) does so with the specific intent that the defendant

"avoid or escape arrest, detention, trial, or punishment."        Mass.

Gen. Laws ch. 274, § 4; see also Commonwealth v. Watson, 165 N.E.3d

1015, 1025 (Mass. 2021); Commonwealth v. Iacoviello, 58 N.E.3d

1032, 1047 (Mass. App. Ct. 2016); Commonwealth v. Clipp, No. 10-

0296, 2011 WL 5182244, at *2 (Mass. Super. Ct. Aug. 26, 2011).

None of the elements purports on its face to require that an

official   judicial   proceeding   or   investigation   be   reasonably

foreseeable -- let alone pending -- at the time of the alleged

accessorial conduct by the defendant. Nor, as I will next explain,

may any of them be read impliedly to so require.

                               - 63 -
                                         A.

             The   first   element      (though     I   suppose       it    could   be

understood to be a compendium of elements in its own right) defines

part of the actus reus of the offense.                    It provides that the

government must prove that the defendant engaged in conduct that

could   qualify     as     obstructive        conduct     of     the       kind   that

§ 1101(a)(43)(S) encompasses.

             But, nothing in the element requires there to be proof

of a linkage of any kind between that conduct and an official

investigation or proceeding into any crime.                    Thus, this element

cannot ensure the required categorical match between the two

offenses.     Nor does the BIA -- or, for that matter, the majority

-- suggest otherwise.

                                         B.

             The second element requires proof that the recipient of

the defendant's aid committed a felony or was an accessory before

the fact to that felony.          This element also defines part of the

actus reus of the offense.            But, it requires no more of a showing

than that the defendant lent the requisite type of aid to the

recipient of it after that recipient had in fact committed a felony

or been an accessory before the fact to it.               Thus, it would appear

that, just like the first element, this element also does not on

its   face   require     proof   of    what   the   BIA    by   its    own    account

understands the generic, federal "obstruction of justice"-related

                                       - 64 -
offense   to    demand:   proof   that   an   official   investigation   is

reasonably foreseeable at the time of the obstructive conduct and

thus that there is a nexus of at least that sort between the

defendant's obstructive conduct and an official investigation.

           In    addition,    the    accessorial    offense    cannot    be

understood to be impliedly subject to a "reasonably foreseeable"-

based nexus requirement as an element, because it applies to being

an accessory after the fact to Massachusetts felonies that are in

their nature no more likely to be detected than the offense at

issue in Marinello.       See, e.g., Mass. Gen. Laws ch. 62C, § 73(a)-

(b), (f) (defining several tax-related felonies, such as the

willful evasion of or "failure to collect or truthfully account"

for a tax); id. ch. 266, § 67C (making it a felony to knowingly

and willfully make a false entry in a book or record of a public

contract); id. § 111C (making certain variations of insurance

fraud a felony); id. ch. 267, § 8 (making it a felony to counterfeit

certain bank bills); id. ch. 267A, § 2 (making it a felony to

launder any amount of money or property); id. ch. 271, § 49(a)

(making it a felony to charge more than twenty percent annual

interest on a loan).        See generally id. ch. 274, § 1 (defining

felonies to include any crime punishable by "imprisonment in the

state prison").     Indeed, one of the tax-related felonies in Mass.

Gen. Laws ch. 62C, § 73, such as willfully evading a tax or

concealing goods on which a tax is to be imposed, seems to me to

                                    - 65 -
be the same as the offense at issue in Marinello, as there is no

reason to presume from the fact that such an offense has been

committed more than that authorities "may eventually catch on" to

the commission of that offense.

              The only potential complication that I can see with this

conclusion is that the underlying "felony" in Silva's case is

murder, which as a general matter is a crime more likely to trigger

an investigation upon its occurrence than a tax offense.                           But,

Silva   asserts,      without   dispute     from     the    government       or     the

expression of any contrary view by the BIA, that the Massachusetts

accessory-after-the-fact statute is not divisible.                    Nor did the

BIA suggest here that Silva's offense of conviction qualifies as

"an offense relating to obstruction of justice" because of the

nature of the predicate felony that the principal committed.

                                       C.

              The third element does require proof that the defendant

accused   of    the   accessorial    conduct     lent      aid   to   the   one    who

committed the felony or was an accessory before the fact to it

"knowing that [the person being assisted] ha[d] committed a felony

or has been accessory thereto before the fact."                  Mass. Gen. Laws

ch. 274, § 4.      But, proof of such knowledge -- which is all that

this element requires -- cannot demonstrate the kind of nexus that

the   BIA's    Marinello-based      "in   the    offing"     standard       requires

between   obstructive      conduct    and       an   investigation:         that    an

                                     - 66 -
investigation into that felony was in fact reasonably foreseeable

at the time of the accessorial conduct.    Nor did the BIA suggest

that, given the principal's predicate crime in Silva's case, proof

of such a nexus was necessarily required to convict Silva of this

accessorial crime.

                                 D.

          That leaves the fourth element, which requires proof

that the defendant engaged in the alleged accessorial conduct "with

intent that [the principal or accessory before the fact] shall

avoid or escape detention, arrest, trial or punishment," Mass.

Gen. Laws ch. 274, § 4.   The majority rightly notes that "[a]bsent

an investigation, there can be no prosecution and no detention,

arrest, trial, or punishment to avoid or escape."   Maj. Op. at 28.

But, this element does not require proof that detention, arrest,

trial or punishment is reasonably foreseeable.      Rather, it is a

classic mens rea element that does not concern the actus reus at

all.

          Nor does the element require proof -- as a means of

proving the defendant's mental state -- that an investigation was

in fact in the offing (or, for that matter, was even reasonably

foreseeable under any understanding of that constraint).        The

element requires proof merely that the defendant lent certain kinds

of aid to the one who committed a felony or was an accessory before

the fact to that felony with the intent to help that recipient

                               - 67 -
evade arrest, trial, punishment, or detention.          See Watson, 165

N.E.3d at 1025.

          In   fact,   it   appears   that   under   this   Massachusetts

offense the defendant need not even have been shown to have

reasonably but mistakenly believed that an official investigation

was in the offing when he lent such aid.       It instead appears that

he need only be shown to have subjectively believed -- even if

unreasonably -- that such an investigation was in the offing when

he did so. Cf. Commonwealth v. Liebenow, 20 N.E.3d 242, 250 (Mass.

2014) (holding that a defendant's honest but unreasonable belief

that property was abandoned was sufficient to establish a defense

that turned on that honest belief); Commonwealth v. Lahens, 177

N.E.3d 935, 942 (Mass. App. Ct. 2021) ("Specific intent crimes are

commonly identified by the presence of a subjective intent to cause

a result that is separate from the crime's actus reus." (citing 1

W.R. LaFave, Substantive Criminal Law § 5.2(e) (3d ed. 2018)));

Commonwealth v. Cachopa, No. 09-P-2337, 2014 WL 5461490, at *2

(Mass. App. Ct. Oct. 29, 2014) (inquiring into the defendant's

state of mind to determine if evidence was sufficient to support

a conviction under the accessory after the fact statute); Clipp,

2011 WL 5182244, at *2 (same for an indictment).

          Proof of no more than that the defendant held a belief

(and not necessarily even an objectively reasonable one) about the

investigation being reasonably foreseeable as of the time of his

                                - 68 -
accessorial      conduct     is    not   proof    of   the   investigation   being

reasonably foreseeable in fact as of that time.                 As such, proof of

that sort is not proof of what the BIA -- and thus the majority --

agrees the generic, federal offense in § 1101(a)(43)(S) requires.

See Uppal v. Holder, 605 F.3d 712, 718 (9th Cir. 2010) (finding a

Canadian criminal offense not to be a categorical match to a crime

involving moral turpitude because the Canadian statute "require[d]

only    that    the   risk    of    harm   resulting     from   the   assault   be

'objective[ly] fores[eeable],'" while the relevant crime of moral

turpitude required "subjective knowledge of a factor indicating

risk to another").

               To be sure, in finding here that the Massachusetts

accessorial offense at issue is a categorical match for the

generic, federal offense referred to in § 1101(a)(43)(S), the BIA

does rely on this fourth element and does state that "[t]here would

be little reason for a defendant to be an accessory after the fact

in this manner unless an investigation or proceedings [sic] was

reasonably foreseeable" (internal quotation marks omitted).30 But,

the BIA ignores the obvious point that a defendant can have an

intention to lend aid for such a purpose without there being any

proof that, in fact, the purpose could be accomplished. Cf. United

       The Fourth Circuit also rested its decision on a similar
       30

specific intent element in interpreting a Virginia statute. Pugin,
19 F.4th at 454.

                                         - 69 -
States v. Zhen Zhou Wu, 711 F.3d 1, 18 (1st Cir. 2013) ("[E]ven

where the evidence is sufficient to show the necessary mens rea,

the government still must always 'meet its burden of proving the

actus reus of the offense.'" (quoting United States v. Whiteside,

285 F.3d 1345, 1353 (11th Cir. 2002))).

          One need only consider the case in which the felon tells

the accessory that he, the felon, is sure to be arrested as a means

of inducing the accessory to lend assistance.           If, in fact, there

is no evidence to show that it was reasonably foreseeable at the

time the assistance was provided by the accessory that authorities

would investigate the felon's unlawful conduct -- and there was

instead at most evidence at that time that authorities "may" do so

"eventually" -- the BIA's own articulated standard for proving the

nexus would not be met even though the specific intent requirement

of the Massachusetts accessory-after-the-fact offense would be

satisfied.     Cf., e.g., United States v. De Leon, 270 F.3d 90, 92

(1st Cir. 2001) (recognizing that an offense "is a specific intent

crime" because it "requires a subjective intent" to achieve a

specific end); Cachopa, 2014 WL 5461490, at *2; Clipp, 2011 WL

5182244, at *2.

                                   E.

          In    sum,   careful   attention   to   the    elements   of   the

Massachusetts accessorial offense of which Silva was convicted and

the elements of the generic, federal "obstruction of justice"-

                                 - 70 -
related offense referred to in § 1101(a)(43)(S) -- as described by

the BIA -- shows that the two offenses (so understood) are not a

categorical match.        And that is so, even if the generic, federal

offense requires no more of a nexus between the defendant's

obstructive conduct and an investigation or proceeding than the

BIA   has    determined    that   offense      to    require,     given   both   the

Marinello-informed        "in   the   offing"       gloss    on   the   "reasonably

foreseeable" standard that the BIA holds defines that offense's

nexus      requirement    and   the   fact   that     this    nexus     requirement

constrains the actus reus of that offense.              Thus, there is no basis

for us to uphold the BIA's conclusion that Silva's offense of

conviction is a categorical match for it.31

                                        V.

              The majority contends that I am mistaken in reaching

this conclusion.          It does so in part by emphasizing that in

applying the categorical approach we may not imagine "fanciful,

hypothetical scenarios."          United States v. Fish, 758 F.3d 1, 6

(1st Cir. 2014) (citing Gonzales v. Duenas-Alvarez, 549 U.S. 183,

193 (2007)); see also United States v. Starks, 861 F.3d 306, 315

(1st Cir. 2017).     The majority points in this regard to the absence

of any reported cases in Massachusetts of prosecutions for the

       The "relating to" words in § 1101(a)(43)(S) still retain a
      31

function: they pick up inchoate versions of an offense that is for
"obstruction of justice."

                                      - 71 -
accessory after the fact offense that is at issue in circumstances

in which the defendant's obstructive conduct did not have a nexus

to a reasonably foreseeable investigation or proceeding.

          But, the categorical approach has never been understood

to make the test of a state law's legally operative scope wholly

dependent on the presence of reported cases of actual prosecutions

for such conduct, in part because reported cases may not be

representative of charging practices.    Da Graca v. Garland, 23

F.4th 106, 113-14 (1st Cir. 2022); Swaby v. Yates, 847 F.3d 62,

65-66 (1st Cir. 2017) (noting that the Duenas-Alvarez limitation

"has no relevance" to a case where the text of a state law clearly

prohibited certain conduct but the petitioner "had failed to show

that there was a realistic probability that [the state] would

actually prosecute offenses" derived from that conduct). Nor would

such a test make sense.

          The outcome under the categorical approach depends on

what the statute setting forth the offense at issue is fairly read

to require the government to prove.     It does not depend on how

aggressively prosecutors choose to enforce that offense or the

actual conduct of defendants in committing it.     See Swaby, 847

F.3d at 65-66.32

     32 For this reason, the majority's point that "Silva's plea
leaves no doubt that he intended to obstruct a reasonably
foreseeable investigation," Maj. Op. at 5 n.2, is irrelevant to

                             - 72 -
            I agree that we may not stretch the text of a criminal

statute to cover conduct that we have no good reason to conclude

that the statute in fact reaches.       But, we must construe such a

statute to reach the conduct that its text plainly does reach.

And, that is so regardless of whether any case involving such

conduct has been prosecuted and then resulted in a published

opinion.    See United States v. Burghardt, 939 F.3d 397, 409 (1st

Cir. 2019) (reaffirming that we should "avoid treating the state

offense as if it is narrower than it plainly is." (internal

quotation marks and alterations omitted) (quoting Swaby, 847 F.3d

at 66)).

            Thus, what matters here is what is clear from the text

of the state-law statute that sets forth the accessorial offense

at issue.    And, what is clear from that text is both that the

offense may be committed under Massachusetts law with respect to

tax evasion and that the state may prove the commission of that

accessorial offense in relation to that type of felony without

proving that any investigation into that felony was "in the

this case. The categorical approach demands that "we look 'not to
the facts of the particular prior case,' but instead to whether
'the state statute defining the crime of conviction' categorically
fits within the 'generic' federal definition of a corresponding
aggravated felony." Moncrieffe, 569 U.S. at 190 (quoting Duenas-
Alvarez, 549 U.S. at 186). A defendant's plea in an individual
case cannot define the elements of a state law offense to be other
than what the statutory text that sets forth that offense -- and
the state's highest court's interpretation of it -- defines those
elements to be.

                               - 73 -
offing."    Thus, it is clear that there is no requirement to prove

a nexus of the "in the offing"-constrained sort that the BIA has

determined must be proved as part of the actus reus of an "offense

relating to obstruction of justice."

            The majority does attempt to respond to this line of

argument.    It does so by asserting that the state law accessorial

offense at issue here is a categorical match for the "obstruction

of justice"-related offense referred to in § 1101(a)(43)(S) only

so long as the underlying "felony" for that accessorial offense is

one that the majority understands to be a "serious" felony.                The

majority then goes on to hold that the accessorial offense of which

Silva was convicted is such a categorical match precisely because

Silva was convicted of being an accessory after the fact to such

a "serious" felony -- namely, murder.

            But, no party to the case or the BIA has indicated that

the   accessorial   offense   at   issue    either   is   divisible   or    is

indivisible but, contrary to its plain text, has an implicit

"seriousness" limitation that makes it just fine to be an accessory

after the fact to a tax crime.       Nor is the accessorial offense in

Silva's case one for which the BIA's "reasonably foreseeable"-

based nexus had to be proved as part of its actus reus.          I thus do

not understand how the basis on which the majority purports to be

explaining away Marinello's significance to this case -- which, I

note, is not the bass on which the BIA itself relied -- comports

                                   - 74 -
with the categorical approach to which the majority purports to be

faithful.

            I would add only in this connection that the "traditional

concept"    of   accessory    after    the     fact     offenses   is    that   "the

accessory's liability derives from that of his principal."                      Model

Penal Code § 242.3 (Am. L. Inst. 1985); see also 5 Tucker's

Blackstone *35 (defining an accessory as "he who is not the chief

actor in the offense . . . but is someway concerned therein").

For that reason, there was no need at common law to require proof

for such a crime that the aid to the felon that the accessory

provided in fact interfered with an investigation that was "in the

offing."    It was enough to require proof that the accessory shared

some culpability for the principal's crime, which could be proved

through evidence of his culpable mental state at the time that he

lent the aid.

            By   contrast,    offenses       of   the    kind   that    Blackstone

labeled as ones against "public justice" -- which are the kinds of

offenses    that   we   now   usually    call     "obstruction      of    justice"

offenses, see Maldonado v. Commonwealth, 829 S.E.2d 570, 575 (Va.

Ct. App. 2019) (looking to Blackstone's list of offenses against

public justice to determine the meaning of obstruction of justice

at common law); People v. Jenkins, 624 N.W.2d 457, 465 (Mich. Ct.

App. 2000) (same) -- were different.              The criminal liability of

the one who committed the offense against public justice was

                                      - 75 -
understood to be derived from his conduct as a principal in his

own right based on his having done something criminal in and of

itself -- impeding the administration of justice.                     See, e.g.,

5 Tucker's Blackstone *127-41; Wharton's Criminal Law §§ 562, 570

(15th ed. 1996).

            As a result, it is not "fanciful" to conclude that

Silva's offense of conviction requires no proof of the kind of

nexus     between   obstructive       conduct     and   an    investigation       or

proceeding that the majority and the BIA acknowledge Congress did

require for the generic, federal "obstruction of justice"-related

offense    referred       to   in    § 1101(a)(43)(S).         Rather,    such    a

construction of Silva's offense of conviction merely results in

that offense being different from an "obstruction of justice"

offense in a way that even Blackstone would recognize.                5 Tucker's

Blackstone      *37-39,    *127-41    (treating    those     types   of   offenses

separately in distinct chapters of his treatise).

            The majority separately takes issue with my invocation

of Marinello, to the extent that I take the view that the BIA

relied     on    Marinello's         understanding      of    the    "reasonably

foreseeable" standard to define the required nexus for an "offense

relating to obstruction of justice" under § 1101(a)(43)(S).                      The

majority focuses in doing so on the fact -- which I do not dispute

-- that the Court there did not have occasion to decide whether

the evidence in that specific case could suffice to satisfy the

                                       - 76 -
"in the offing"-based nexus requirement that the Court there

described.

          But, as I have already explained, proof of the commission

of a predicate crime -- or the awareness of its commission by the

one guilty of the accessorial offense -- is not proof that an

investigation into that predicate crime was in fact reasonably

foreseeable at the time of the accessorial conduct in the "in the

offing" sense.   It is at most proof that authorities "may" (or of

the defendant's knowledge that the authorities may) "eventually"

catch on to that predicate crime's commission.             But, that is

exactly the sort of proof that Marinello clearly deemed inadequate

to satisfy the "reasonably foreseeable" standard that the Court

described in that case.

          Thus, because the state law accessorial offense of which

Silva was convicted requires, as to its actus reus, no more than

proof of the defendant's mere awareness of the predicate crime's

commission -- which, as best I can tell, is also a point that the

majority does not dispute -- that state law accessorial offense

cannot be a categorical match for the "obstruction of justice"-

related offense set forth in § 1101(a)(43)(S) as the BIA has

described that offense's elements.        For, while the BIA does point

to the specific intent element of the Massachusetts accessory-

after-the-fact   offense   in   concluding    otherwise,   the   majority

overlooks the way that the BIA itself defines the actus reus of an

                                 - 77 -
"offense relating to obstruction of justice" and so mixes up actus

reus and mens rea elements in a way that the elements-based

categorical approach simply does not permit.

                                     VI.

            I have explained before why I do not agree with the

criticism    that    the    categorical     approach   permits   technical

inquiries to yield the conclusion that objectively concerning

criminal conduct is of no concern to the Congress that enacted the

measure that imposes the special, adverse consequence at issue.

See United States v. Faust, 853 F.3d 39, 61-66 (1st Cir. 2017)

(Barron,    J.,   concurring).      But,    the   objection   that   such   a

technical, elements-based inquiry misses the forest for the trees

is especially misplaced here, given the history that I have just

recounted    about   how    accessorial     offenses   historically     were

understood to be conceptually distinct from offenses for impeding

the   administration       of   public   justice.      And,   indeed,   the

organization of modern criminal codes still reflects such an

understanding of those two types of offenses being distinct.            See,

e.g., 18 U.S.C. § 3, ch. 73; Mass. Gen. Laws ch. 268, ch. 274,

§ 4; cf. Da Graca, 23 F.4th at 112 (determining the scope of a

state criminal statute in part by looking to certain of the state's

other criminal statutes, and approvingly noting that the BIA

"interpreted the existence of a separate California joyriding

statute to cabin the breadth of the California unauthorized use

                                   - 78 -
[of a motor vehicle] statute").    Thus, if history is our guide,

there is quite good reason to think that the Congress that singled

out offenses "relating to obstruction of justice" -- even accepting

as the majority does that the BIA is right in how expansively it

has defined that category of offenses -- was not a Congress that

had in view the kind of accessorial crime of which Silva was

convicted.

          I do not mean to suggest that anything would prevent a

state from defining the elements of an offense that it labels as

an accessorial one in a way that would make that offense a match

for "an offense relating to obstruction of justice," as the BIA

understands that offense.    But, as I have explained, there is no

indication that Massachusetts has done so here.

          Accordingly,   I   conclude   that   although   Silva   was

convicted of being an accessory after the fact to a felony, neither

the BIA nor the majority has established that he has been convicted

of an "offense relating to obstruction of justice," such that he

may be deemed to have committed an "aggravated felony" within the

meaning of the INA.   I therefore would grant Silva's petition for

review and so, respectfully, dissent.

                               - 79 -
