    TORRUELLA, Circuit Judge.              We are called upon to decide
    an   issue    of       first      impression    in   this    circuit     --    whether     to
    recognize         a    "joint       participant"     exception      to        the     spousal
    testimonial privilege.               For the following reasons, we affirm the
    district court's conclusion that recognition of such an exception
    is not warranted.
    I.
    Before moving forward, a brief survey of the spousal
    testimonial privilege and the rationales that have traditionally
    undergirded it is in order.
    A.
    The spousal testimonial privilege is an evidentiary
    privilege that protects a defendant's spouse from having to take
    the witness stand to testify against the defendant.                             See United
    States v. Breton, 
    740 F.3d 1
    , 9-10 (1st Cir. 2014).                            It has deep
    and "ancient roots" in the history of the common law, and descends
    "from two canons of medieval jurisprudence."                        Trammel v. United
    States, 
    445 U.S. 40
    , 43-44 (1980).                     The first of these canons
    involved the principle that "an accused was not permitted to
    testify      in       his   own    behalf   because     of    his   interest          in   the
    proceeding."           
    Id. at 44.
        The second was "the concept that husband
    and wife were one, and that since the woman had no recognized
    separate legal existence, the husband was that one."                            
    Id. Based -2-
    on these two rationales, the traditional rule mandated that "what
    was inadmissible from the lips of the defendant-husband was also
    inadmissible from his wife."          
    Id. These two
    rationales are now "long-abandoned," and the
    modern justifications for the privilege focus instead on a pair of
    distinct      but   related   rationales:     "fostering   the   harmony    and
    sanctity of the marriage relationship," 
    id., and the
    broader
    societal interest in "avoid[ing] the unseemliness of compelling
    one spouse to testify against the other in a criminal proceeding,"
    United States v. Yerardi, 
    192 F.3d 14
    , 18 (1st Cir. 1999) (citing
    
    Trammel, 445 U.S. at 44-45
    , 52-53 & n.12); see also Hawkins v.
    United States, 
    358 U.S. 74
    , 77 (1958) ("The basic reason the law
    has refused to pit wife against husband or husband against wife in
    a trial where life or liberty is at stake was a belief that such
    a policy was necessary to foster family peace, not only for the
    benefit of husband, wife and children, but for the benefit of the
    public   as    well.").       This   latter   rationale    has   been   further
    explained as stemming from "the 'natural repugnance in every fair-
    minded person to compelling a wife or husband to be the means of
    the other's condemnation.'"          In re Grand Jury Subpoena, 
    755 F.2d 1022
    , 1028 (2d Cir. 1985) (quoting 8 Wigmore, Evidence § 2228, at
    217).
    -3-
    B.
    Just       as     the    rationales     underlying         the   spousal
    testimonial privilege have changed over time, the nature and
    contours   of    the     privilege     have     themselves    evolved    since   the
    privilege's common law origins.
    In     its      traditional    form,    the      spousal    testimonial
    privilege was, in fact, an absolute rule that completely barred a
    spouse from giving any testimony in his or her defendant spouse's
    case, even testimony that would support the defendant's cause.
    
    Trammel, 445 U.S. at 43-44
    .            This rigid rule "remained intact in
    most common-law jurisdictions well into the 19th century."                       
    Id. at 44
    (citing 8 Wigmore, Evidence § 2333).                     That was the case
    until 1933, when the Supreme Court softened the limitations of
    this rule "so as to permit the spouse of a defendant to testify in
    the defendant's behalf."            Id.; see also Funk v. United States, 
    290 U.S. 371
    , 380-81 (1933).              However, it was still the rule that
    "either    spouse      could    prevent    the    other   from    giving     adverse
    testimony."      
    Trammel, 445 U.S. at 44
    (citing 
    Funk, 290 U.S. at 373
    ).
    The Supreme Court next considered the scope of the
    spousal testimonial privilege in Hawkins v. United States, 
    358 U.S. 74
    (1958).          The defendant in that case sought to invoke the
    spousal testimonial privilege to prevent his wife from voluntarily
    -4-
    testifying against him.              
    Id. at 74-75.
         Despite the Government's
    invitation to draw a distinction between compelling a spouse's
    testimony on one hand and allowing her to testify voluntarily on
    the   other,    and      the    Court's    acknowledgement          of       "the   critical
    comments that the common-law rule had engendered," the Court
    nevertheless allowed the defendant to bar his wife from testifying
    against him.        
    Trammel, 445 U.S. at 46
    .                 Finding that "the law
    should not force or encourage testimony which might alienate
    husband     and       wife,     or     further      inflame        existing         domestic
    differences," the Court elected to maintain the "rule which bars
    the testimony of one spouse against the other unless both consent."
    
    Hawkins, 358 U.S. at 78-79
    .
    The most recent occasion on which the Supreme Court has
    addressed the scope of the spousal testimonial privilege is Trammel
    v. United States, 
    445 U.S. 40
    (1980).                   The Court was once again
    confronted with a defendant who sought to assert the spousal
    testimonial privilege to prevent his unindicted co-conspirator
    wife from voluntarily testifying against him in his criminal trial.
    
    Id. at 42-43.
            In that case, the Tenth Circuit had held that the
    defendant's       wife    should      be   permitted    to    testify         against    her
    husband,    declaring          an    exception     to   the       spousal      testimonial
    privilege      when      the    "defendant        husband     .    .     .    has    jointly
    participated in a criminal conspiracy with his wife."                                United
    -5-
    States v. Trammel, 
    583 F.2d 1166
    , 1169 (10th Cir. 1978).            Instead
    of adopting the Tenth Circuit's approach, the Court found that
    "[t]he ancient foundations for so sweeping a privilege have long
    since disappeared," and held that "the existing rule should be
    modified so that the witness-spouse alone has a privilege to refuse
    to testify adversely[.]         [T]he witness may be neither compelled
    to testify nor foreclosed from testifying."           
    Trammel, 445 U.S. at 52-53
    .
    C.
    The    joint     participant     exception   to   the    spousal
    testimonial privilege the Government asks us to adopt, by contrast,
    does not have anywhere near as long a history as the privilege
    itself does.       The first court to recognize an exception to the
    spousal testimonial privilege for a witness accused of engaging in
    a criminal conspiracy with his or her defendant spouse was the
    Seventh Circuit in United States v. Van Drunen, 
    501 F.2d 1393
    (7th
    Cir. 1974).       In recognizing such an exception, that court found
    that doing so appropriately "limits the privilege to those cases
    where it makes most sense, namely, where a spouse who is neither
    a victim nor a participant observes evidence of the other spouses's
    [sic] crime."      
    Id. at 1397.
    A few years later, the Tenth Circuit followed the Seventh
    Circuit's   lead     in    adopting   the   joint   participant   exception.
    -6-
    
    Trammel, 583 F.2d at 1170-71
    .     That court relied in substantial
    part on the Seventh Circuit's reasoning in Van Drunen -- that the
    goal of preserving the family "does not justify assuring a criminal
    that he can enlist the aide of his spouse in a criminal enterprise
    without fear that by recruiting an accomplice or coconspirator he
    is creating another potential witness."     
    Id. at 1169-70
    (internal
    quotation marks omitted) (quoting Van 
    Drunen, 501 F.2d at 1396
    ).
    The other courts of appeals that have considered this
    issue have reached differing conclusions.     The Second, Third, and
    Ninth Circuits have refused to recognize the joint participant
    exception.     See United States v. Ramos-Oseguera, 
    120 F.3d 1028
    ,
    1042 (9th Cir. 1997), overruled on other grounds by United States
    v. Nordby, 
    225 F.3d 1053
    (9th Cir. 2000); In re Grand Jury
    
    Subpoena, 755 F.2d at 1026-28
    ; Appeal of Malfitano, 
    633 F.2d 276
    ,
    278-80 (3d Cir. 1980).    By contrast, the Seventh Circuit continues
    to recognize such an exception even after the Supreme Court's
    decision in Trammel.     United States v. Clark, 
    712 F.2d 299
    , 300-
    02 (7th Cir. 1983) (quoting Van 
    Drunen, 501 F.2d at 1397
    ).1
    The Third Circuit based its rejection of the exception
    on several inter-related grounds.      First, that court disputed the
    1  We have been unable to find, and the parties do not point to a
    case in which the Tenth Circuit again applied the joint participant
    exception to the spousal testimonial privilege after Trammel.
    -7-
    premise that "there is no need in fact to protect" marriages where
    the   partners      are    involved    in   crime     because   those   marriages
    "disintegrate and dissolve."            
    Malfitano, 633 F.2d at 278
    .             The
    court pointed out that "[t]he spouses in fact may be very happy,"
    and "the fact that under Trammel the witness spouse is the holder
    of    the   privilege      completely   satisfies       any   concern    that   the
    privilege not be extended to marriages that in fact need no
    protection." 
    Id. Second, that
    court also disputed the proposition
    that "marriages with partners that engage in crime should not be
    protected."        
    Id. (emphasis added).
         The court emphasized that the
    assumption that "because of what may be an isolated criminal act,
    the marriage has no social value whatsoever" might not be true in
    all cases.     
    Id. Next, the
    court opined that it was "not confident that
    courts can assess the social worthiness of particular marriages or
    the   need    of    particular    marriages     for    the    protection   of   the
    privilege."         
    Id. at 279.
       Given    the    difficulty      that    such
    determinations would involve, the court stated that it "d[id] not
    think that the court should 'condition the privilege . . . on a
    judicial determination that the marriage is happy or successful
    one.'"      
    Id. (quoting United
    States v. Lilley, 
    581 F.2d 182
    , 189
    (8th Cir. 1978)).          Finally, the court observed that "[g]iven the
    intimacy of marriage and the fact that conspiracy is a rather
    -8-
    flexible concept, it will be quite easy to allege that the spouses
    are partners."     
    Id. Therefore, "recognition
    of an exception where
    it can be said that both spouses are involved will tend to
    undermine the marriage precisely in the manner that the privilege
    is designed to prevent."         
    Id. The Second
    Circuit echoed some of the same concerns.
    That court stated that it was "unable to accept the proposition
    that a marriage cannot be a devoted one simply because at some
    time the partners have decided to engage in a criminal activity."
    In re Grand Jury 
    Subpoena, 755 F.2d at 1026
    .                Further, it also
    based its conclusion, in part, on the importance of protecting the
    marriage relationship from the "'natural repugnance in every fair-
    minded person to compelling . . . the culprit to the humiliation
    of being condemned by the words of his intimate life partner,'
    forced   from    her   by    governmental    compulsion."      
    Id. at 1028
    (citation omitted) (quoting 8 Wigmore, Evidence § 2228 at 217).
    On the other side of the split is the Seventh Circuit,
    which is the only circuit to have recognized a joint participant
    exception   to   the     spousal   testimonial   privilege     post-Trammel.
    
    Clark, 712 F.2d at 300-02
    .         Relying heavily on its precedent, the
    court reiterated that the spousal testimonial privilege should be
    limited "to those cases where it makes most sense, namely, where
    a spouse who is neither a victim nor a participant observes
    -9-
    evidence of the other spouse's crime," 
    id. at 301
    (quoting Van
    
    Drunen, 501 F.2d at 1397
    ), and that the underlying goal of the
    privilege to preserve the sanctity and harmony of the family
    "do[es] not justify assuring a criminal that he or she could enlist
    the aid of a spouse in a criminal enterprise without fear that by
    recruiting    an     accomplice   the    criminal   was   creating   another
    potential witness," 
    id. at 301
    (citing Van 
    Drunen, 501 F.2d at 1396
    ).    Further, the court stated that "the rehabilitative effect
    of a marriage, which in part justifies the privilege, is diminished
    when both spouses are participants in the crime."               
    Id. at 301
    (citing Van 
    Drunen, 501 F.2d at 1397
    ).              Finally, the Seventh
    Circuit    determined    that     "a   joint   participants   exception   is
    consistent with the general policy of narrowly construing the
    privilege."    
    Id. II. Having
    assayed the history of the spousal testimonial
    privilege and the joint participant exception, we turn to the facts
    of this case.      Because this case has not yet proceeded to trial,
    we draw the relevant facts from the Government's indictment.           See,
    e.g., United States v. Colombo, 
    852 F.2d 19
    , 21 (1st Cir. 1988)
    (using the facts alleged in the indictment in reviewing the
    district court's dismissal of an indictment).
    -10-
    A.
    On   September         25,     2015,   a    confidential       informant
    attempted to call a drug dealer named "Tony."                  Yovannys Guerrero-
    Tejeda ("Guerrero") -- who was recorded by law enforcement without
    her knowledge -– and, in consultation with another individual
    nearby    (alleged     to   have    been    her    husband,    Eric   Pineda-Mateo
    ("Pineda")), told the informant to raise $1,000 to pay part of a
    prior drug debt before arranging another drug transaction.
    Three days later, the informant called Guerrero again
    and "arranged to purchase three fingers of heroin from Guerrero
    and Pineda."       On October 6, 2015, the informant and Guerrero
    exchanged several more phone calls that were covertly recorded by
    law enforcement, and arranged to meet at a New Hampshire mall for
    a drug transaction.         At this meeting, Guerrero gave the informant
    a bag of heroin in exchange for $1,000 in cash.                  Two weeks later,
    the informant arranged a second drug transaction with Guerrero and
    Pineda, after which the informant attempted to set up a third
    transaction.     On November 16, 2015, Guerrero and Pineda appeared
    together   at    the   location      where      they   had   agreed   to   meet   the
    informant and were arrested by the New Hampshire state police and
    others.    In the car, which was registered to Pineda, the police
    found twenty-five grams of fentanyl.
    The Government alleged that the evidence established a
    -11-
    conspiracy between Guerrero and Pineda throughout this series of
    events.   For example, during the recorded phone calls with the
    informant,    Guerrero   repeatedly    referred   to   "her   husband"   and
    negotiated the transactions in concert with him.              Additionally,
    Pineda also appeared to be the person who acquired the heroin
    subsequently sold to the informant.        Furthermore, agents observed
    both Guerrero and Pineda meeting with the informant in person to
    conduct the second transaction, during which Guerrero and Pineda
    spoke to each other in Spanish before speaking in English to the
    informant.     Finally, Guerrero and Pineda were arrested together
    at the location of the planned third drug transaction.
    B.
    On December 2, 2015, a federal grand jury indicted
    Guerrero for one count of conspiracy to possess with intent to
    distribute and conspiracy to distribute heroin and fentanyl, in
    violation of 21 U.S.C. §§ 841(a)(1), 846 (Count 1), and two counts
    of distribution of heroin, in violation of 21 U.S.C. § 841(a)(1)
    (Count 2 and 3).    Pineda was indicted only on Count 1.          Guerrero
    subsequently pleaded guilty to all three counts against her in
    April 2017, while Pineda elected to go to trial.              Intending to
    call her as a witness at trial, the Government subpoenaed Guerrero
    and filed a motion in limine "seeking a determination, pursuant to
    Federal Rule of Evidence 104(a), that her testimony is admissible."
    -12-
    Guerrero subsequently moved to quash the subpoena on the grounds
    that the spousal testimonial privilege prevented the Government
    from compelling her to testify at her husband's trial. 2             In
    response, the Government moved to compel Guerrero's testimony,
    seeking to invoke an exception to the spousal testimonial privilege
    "for a jointly participating spouse in a criminal conspiracy."3
    After a hearing, the district court granted Guerrero's
    motion to quash the subpoena and denied the Government's motion to
    compel Guerrero's testimony at Pineda's trial.     The district court
    acknowledged     the   aforementioned   circuit   split   as   to   the
    recognition of the joint participant exception to the spousal
    testimonial privilege, but ruled that "[t]he weight of authority"
    counseled against the recognition of such an exception.             The
    Government then filed this interlocutory appeal of the district
    court's order.
    III.
    The district court below based its conclusion in part on
    2  Guerrero points out that "she was willing to forego possible
    reductions in her sentence based upon substantial assistance in
    order to maintain her adverse spousal testimonial privilege and
    thereby protect her marriage." She further stated that even if
    this court ruled against her, she would refuse to testify against
    her husband and "would face civil contempt proceedings if
    necessary."
    3  The Government did not challenge the legality of the marriage
    between Pineda and Guerrero before the district court.
    -13-
    its reasoning that the Supreme Court implicitly rejected the joint
    participant exception "by declining to adopt the Tenth Circuit's
    approach" in Trammel.            The Government challenges this finding on
    appeal.       Because a finding that Trammel does entirely foreclose
    the    recognition    of     a     joint    participant        exception      would   be
    dispositive in this appeal, we address that issue first.
    The Government's principal contention is that Trammel
    should    not   be   read    to    foreclose       the    possibility    of    a   joint
    participant exception because the Supreme Court did not address
    the joint participant exception recognized by the Tenth Circuit
    below.    Pineda and Guerrero defend the district court's reasoning
    by arguing that "[d]espite the [G]overnment's invitation to adopt"
    the joint participant exception, the Supreme Court chose to narrow
    the privilege instead by vesting it only in the testifying spouse.
    They contend that the district court correctly interpreted this
    holding on the broader ground of overruling Hawkins as the Court's
    rejection of that exception.               We are not persuaded by Pineda and
    Guerrero's arguments.         Instead, we agree with the Government that
    Trammel is not a categorical bar to the possibility of recognizing
    a     joint    participant        exception       to     the   spousal     testimonial
    privilege.
    Trammel, as the Government accurately points out, does
    not discuss the joint participant exception on which the Tenth
    -14-
    Circuit had rested its decision, let alone opine on its merits.

    Trammel, 445 U.S. at 41-53
    .         We find it difficult to see how
    the Supreme Court rejected an exception that it did not so much as
    mention.     In fact, the Court made clear that it granted certiorari
    in that case "to consider whether an accused may invoke the
    privilege against adverse spousal testimony so as to exclude the
    voluntary testimony of his wife."           
    Id. at 41-42.
       It is axiomatic
    that   the   Supreme   Court   can   grant    a   petition   for   a   writ   of
    certiorari as to virtually any issue in a case it wishes to review,
    and decide cases on any ground it feels is appropriate.                   See,
    e.g., Bosse v. Oklahoma, 
    137 S. Ct. 1
    , 2 (2016) ("[I]t is this
    Court's prerogative alone to overrule one of its precedents."
    (alteration in original) (citations omitted)); Vance v. Terrazas,
    
    444 U.S. 252
    , 258 n.5 (1980) ("[C]onsideration of issues not
    present in the jurisdictional statement or petition for certiorari
    and not presented in the Court of Appeals is not beyond our power,
    and in appropriate circumstances we have addressed them.").
    Applying these principles has several consequences in
    this case.     First, because it is the Supreme Court's prerogative
    to resolve cases on whatever grounds it believes appropriate, we
    think that it would be wrong to interpret the Supreme Court's
    decision to resolve the broader doctrinal question in Trammel as
    implicitly rejecting the narrower ground for affirmance -- the
    -15-
    joint participant exception.     See Cohens v. Virginia, 19 U.S. (6
    Wheat.) 264, 399 (1821) ("It is a maxim not to be disregarded,
    that general expressions . . . are to be taken in connection with
    the case in which those expressions are used.           If they go beyond
    the case, they . . . ought not to control the judgment in a
    subsequent suit.").   Second, we are not convinced that much weight
    should be given to the fact that the Government had "invited" the
    Trammel Court to approve the joint participant exception.          Because
    the Supreme Court's discretion extends not only to the grounds for
    resolving a case but also to the specific issue(s) it reviews, we
    think it unwise to read any dispositive meaning into the lack of
    any discussion of the joint participant exception in the Trammel
    opinion, or the Court's decision not to take up the Government's
    "invitation" to recognize the joint participant exception.             See
    Maldonado Santiago v. Velázquez García, 
    821 F.2d 822
    , 828 (1st
    Cir. 1987) (stating that interpreting the Supreme Court to have
    overruled a line of precedent sub silentio would not "reflect . . .
    a prudent reading of precedent").       The Supreme Court's silence on
    this issue is just that -- silence.
    The   context   in   which    Trammel   was    decided   further
    reinforces the conclusion that the Supreme Court did not implicitly
    foreclose the joint participant exception.        Prior to Trammel, the
    Court had decided Hawkins, in which it held that a criminal
    -16-
    defendant   could   assert    the   spousal   testimonial   privilege   to
    prevent his or her spouse from testifying against him, even when
    the spouse was willing to do 
    so. 358 U.S. at 77
    .   In Trammel, the
    defendant's only claim before the Tenth Circuit was that "the
    admission of the adverse testimony of his wife, over his objection,
    contravened [the Supreme] Court's teaching in Hawkins v. United
    States . . . 
    ." 445 U.S. at 43
    .    The Tenth Circuit rejected this
    argument, concluding that "[n]othing in Hawkins or any other
    reported decision . . . prohibits the voluntary testimony of a
    spouse who appears as an unindicted co-conspirator . . . ."
    
    Trammel, 583 F.2d at 1168
    .     In light of this background, therefore,
    the conclusion that the Supreme Court did not implicitly reject
    the joint participant exception makes sense.          The Supreme Court
    found the Tenth Circuit's decision in Trammel called for "a re-
    examination of Hawkins," which is precisely what the Court did
    without approving or disapproving the joint participant exception
    recognized by the Tenth Circuit.       
    Trammel, 445 U.S. at 42
    .
    Absent guidance to the contrary from the Supreme Court
    -- which we do not find in Trammel -- we decline to hold that
    Trammel completely precludes the possibility of recognizing a
    joint participant exception if the appropriate balancing analysis
    weighs in its favor.         For these reasons, the district court's
    conclusion that the Supreme Court implicitly rejected the joint
    -17-
    participant exception in Trammel is incorrect.
    IV.
    Having determined that Trammel does not squarely resolve
    the question posed by this appeal, we now turn to the district
    court's conclusion not to recognize such a joint participant
    exception.     We review the admission or exclusion of evidence over
    claims of privilege for an abuse of discretion.      In re Grand Jury
    Subpoena, 
    662 F.3d 65
    , 69 (1st Cir. 2011).          However, when the
    issue presented is of a legal nature, those "[r]ulings on questions
    of law are reviewed de novo."     
    Id. A. Rule
    501 of the Federal Rules of Evidence governs claims
    of privilege in the federal courts.        Swidler & Berlin v. United
    States, 
    524 U.S. 399
    , 403 (1998).       That Rule provides that "[t]he
    common law -- as interpreted by United States courts in the light
    of reason and experience -- governs a claim of privilege . . . ."
    Fed. R. Evid. 501.     It empowers the federal courts to "develop[]
    rules of privilege on a case-by-case basis."         United States v.
    Gillock, 
    445 U.S. 360
    , 367 (1980).      Furthermore, the Supreme Court
    has instructed that a privilege should only apply in a particular
    case if it "promotes sufficiently important interests to outweigh
    the need for probative evidence."       Univ. of Pa. v. EEOC, 
    493 U.S. 182
    , 189 (1990) (quoting 
    Trammel, 445 U.S. at 51
    ).
    -18-
    The spousal testimonial privilege is one of the two
    marital privileges recognized under the Federal Rules of Evidence.4
    It "allows one spouse to refuse to testify adversely against the
    other in criminal or related proceedings . . . ."                      
    Breton, 740 F.3d at 9-10
    .       Unlike the marital communications privilege, which
    either spouse may assert, 
    id. at 10,
    "the witness-spouse alone has
    a privilege to refuse to testify adversely; the witness may be
    neither compelled to testify nor foreclosed from testifying."
    
    Trammel, 445 U.S. at 53
    .
    The Government contends that Rule 501's mandate for the
    federal courts to develop the law of evidentiary privileges "in
    light   of       reason   and   experience"      requires    us   to    weigh   the
    Government's need for evidence against the policy rationales that
    underlie     a    claimed   privilege.       A   proper     balancing    of   these
    interests, the Government further argues, justifies recognizing a
    joint participant exception to the spousal testimonial privilege.
    Specifically, the Government points to two features of
    conspiracies that it claims enhances the need for the Government
    4   The other recognized marital privilege is the marital
    communications privilege, which "permits a defendant to refuse to
    testify, and allows a defendant to bar his spouse or former spouse
    from testifying, as to any confidential communications made during
    their marriage." 
    Breton, 740 F.3d at 10
    . The parties agree that
    the marital communications privilege cannot be a basis for
    excluding Guerrero's testimony here.
    -19-
    to be able to gather evidence.           First, the Government argues that
    a "[c]ollective criminal agreement . . . presents a greater
    potential    threat    to   the    public       than   individual   derelicts,"
    Callanan v. United States, 
    364 U.S. 587
    , 593 (1961), a danger that
    it asserts is "peculiar."         Not allowing the Government to abrogate
    the privilege in this context "wrongly places the law on the side
    of protecting conspiracies within a marriage," and therefore the
    Government "has a particularly strong need for evidence so that it
    can dismantle the conspiracy before it inflicts additional harms
    on the public."    Second, the Government points to the inchoate and
    secretive nature of conspiracies.              The Government emphasizes that
    it often needs to obtain testimony of a co-conspirator in order to
    subvert the conspiracy, and cites to the hearsay exception for
    statements of a co-conspirator, Fed. R. Evid. 801(d)(2)(E), to
    highlight the importance of access to this critical evidence in
    conspiracy prosecutions.
    On the other side of the scale, the Government argues
    that   society's      interest     in    preserving      marital    harmony   is
    "diminished in the particular context of conspiracy prosecutions."
    Married couples who conspire to commit crimes, the Government
    urges, "have abused the marital privilege granted to them by the
    state."     Because "[i]t would be odd to permit a spouse to invoke
    the spousal testimonial privilege . . . to protect a criminal
    -20-
    conspiracy formed within the marriage that is harmful to the
    state," the Government argues that the force of the public policy
    behind the privilege is "at its nadir" in conspiracy cases.
    The    Government,        however,     never        addresses    the
    "experience" side of Rule 501's equation in arguing for the
    exception to the longstanding spousal testimonial privilege. This
    Court has recognized the spousal testimonial privilege without the
    joint-participant exception for many years, and yet the Government
    never presents an argument as to how our experience with the
    spousal testimonial privilege shows that we should now recognize
    this exception when we did not in the past.5            See, e.g., Jaffee v.
    Redmond, 
    518 U.S. 1
    , 6 (1996) (citing the unanimous agreement of
    the 50 states and the "skyrocket[ing]" demand for counseling
    services as evidence of how our "experience" with mental health
    had   changed   such   that   the    Court     needed    to    recognize   the
    psychotherapist privilege).         When reason, by itself, fails to
    5  The Government does suggest in a footnote to its brief that the
    treatment of the privilege in the states supports its position
    that we should judicially carve out the joint-participant
    exception to this privilege pursuant to Rule 501.         But the
    Government does not dispute that a substantial majority of the
    states recognize the spousal testimonial privilege without carving
    out such an exception. In fact, the Government's own account of
    state practice reveals that only two of the thirty states that
    recognize the privilege have adopted the exception it favors.
    Moreover, as the Government acknowledged at oral argument, of the
    states that have limited the privilege, an overwhelming number
    have done so via legislation rather than through judicial means.
    -21-
    provide an unequivocal interpretation, a court's experience with
    the privilege weighs even more on its decision.                     See Swidler &
    Berlin v. United States, 
    524 U.S. 399
    , 410 (1998) (noting that
    where "[i]t has been generally, if not universally, accepted, for
    well over a century, that the attorney-client privilege survives
    the   death    of    the   client,"    the    Court   would    need    more   than
    "thoughtful speculation" to justify recognizing a new exception).
    B.
    It seems clear then that the interests the spousal
    testimonial privilege is designed to serve continue to be quite
    substantial.         Compared   to    these   interests,      the    Government's
    asserted evidentiary interests on the other side of the scale are,
    in our view, less hefty.         The inchoate and secretive features of
    conspiracies to which the Government alludes in support of its
    argument are common to every conspiracy prosecution, and are not
    alleviated or exacerbated by the fact that some or both members of
    the conspiracy are married to each other.                By the Government's
    logic, the difficulties involved in prosecuting conspiracies would
    outweigh the significant countervailing interests that underlie a
    number of other evidentiary privileges as well, including, for
    example,       the    Fifth     Amendment       privilege      against        self-
    incrimination.6 The Fifth Amendment, of course, is a constitutional
    6   Of course, the other half of the Government's argument under
    -22-
    right, and not just a matter of common law as is the spousal
    testimonial privilege.        But given that both privileges are deeply
    rooted   in    history,   the   interests    that   underlie   the   spousal
    testimonial privilege are similarly significant.7
    The force of the Government's argument as to the need
    for   evidence    in   this   context   is   further   undermined    by   its
    acknowledgement that "[t]here are many types of evidence that a
    court may consider to determine whether a couple was engaged in a
    criminal agreement, without requiring testimony from the unwilling
    spouse."       The Government's tacit admission that there is no
    shortage of other evidence (at least in the mine run of cases)
    with which the Government can make the predicate showing necessary
    to invoking its proposed joint participant exception belies its
    claim that the need for evidence is particularly high in conspiracy
    the balancing analysis is that the rationales underlying the
    spousal testimonial privilege are significantly diminished in the
    specific context of conspiracy prosecutions. As further explained
    below, however, that argument is also unpersuasive.
    7  The Government also briefly refers to the treatment of co-
    conspirators' statements as non-hearsay, Fed. R. Evid. 801(d)
    (2)(E), as evidence of the law's preference for "facilitat[ing]
    the presentation of co-conspirator statements" in criminal trials.
    This comparison is inapt. Rule 801(d)(2)(E) rests on a theory of
    agency, "the underlying concept being that a conspiracy is a common
    undertaking where the conspirators are all agents of each other
    and where the acts and statements of one can be attributed to all."
    Bourjaily v. United States, 
    483 U.S. 171
    , 188 (1987) (Blackmun,
    J., dissenting).     The rule does not manifest a legislative
    preference for co-conspirator statements generally.
    -23-
    cases.      We are therefore not persuaded that the Government's need
    to pierce the spousal testimonial privilege is cognizably greater
    in cases where the spouses are alleged to have engaged in a
    criminal conspiracy than in other cases.
    The Government also contends that "the public policy in
    favor of applying the privilege is weak in conspiracy cases."                   We
    also find that argument unpersuasive.                 As the Third Circuit
    observed, this argument seemingly assumes "that because of what
    may be an isolated criminal act, the marriage has no social value
    whatsoever," which "may not be true" in all cases.             
    Malfitano, 633 F.2d at 278
    .      In   fact,   "the   marriage   may   well   serve   as    a
    restraining influence on couples against future antisocial acts
    and may tend to help future integration of the spouses back into
    society."      
    Id. Likewise, the
    Second Circuit has stated that it
    is "unable to accept the proposition that a marriage cannot be a
    devoted one simply because at some time the partners have decided
    to engage in a criminal activity."            In re Grand Jury 
    Subpoena, 755 F.2d at 1026
    .        We agree in large part with the reasoning of these
    two courts.
    The Supreme Court once described a marriage as "a coming
    together for better or for worse, hopefully enduring, and intimate
    to the degree of being sacred."            Griswold v. Connecticut, 
    381 U.S. 479
    , 486 (1965).       The Court recently underscored that "[n]o union
    -24-
    is more profound than marriage, for it embodies the highest ideals
    of love, fidelity, devotion, sacrifice, and family.                  In forming a
    marital union, two people become something greater than once they
    were."    Obergefell v. Hodges, 
    135 S. Ct. 2584
    , 2608 (2015).                      In
    light of these statements, we decline to engage in value judgments
    about which marriages are worthy of protection and which are not,
    and find that "reason and experience" counsels our refraining from
    recognizing      an     exception   that    requires     courts    to   make     such
    determinations.
    In arguing that the interest in marital harmony is not
    always paramount, the Government also points to "long-standing
    criticism of the privilege by the Supreme Court, the States and
    commentators."        However, to the extent the Government is correct
    that the spousal testimonial privilege is rightly criticized as
    being    too    broad,    we   believe     that   this   concern   was    squarely
    addressed by the Supreme Court in Trammel.               The Government, after
    all, cites to Trammel itself for its criticism of the privilege's
    breadth and capacity to impede a court's path to the truth.                      Yet,
    when provided the opportunity to address this problem, the Supreme
    Court chose to vest the privilege only in the testifying spouse
    instead of opting for the narrower remedy of recognizing a joint
    participant exception.          As previously noted, this holding is not
    conclusive       that    no    joint     participant     exception      should     be
    -25-
    recognized, but it does significantly undermine the Government's
    claim that the law as it currently stands does not strike the
    proper    balance     between     protecting     the   marriage    and   the
    Government's need for evidence in conspiracy cases.
    We also decline the Government's invitation to follow
    the Seventh Circuit's lead because we do not find persuasive the
    two rationales on which the Seventh Circuit's view is based.             As
    to the first rationale, that the spousal testimonial privilege
    "did not justify assuring a criminal that he or she could enlist
    the aid of a spouse in a criminal enterprise without fear that
    . . .    the    criminal   was   creating    another   potential   witness,"
    
    Clark, 712 F.2d at 301
    (quoting Van 
    Drunen, 501 F.2d at 1396
    ),           we
    agree with the Second Circuit that Trammel addressed this concern
    by vesting the privilege in only the witness spouse, see In re
    Grand Jury 
    Subpoena, 755 F.2d at 1026
    .              Regarding the Seventh
    Circuit's second rationale that "the rehabilitative effect of a
    marriage, which in part justifies the privilege, is diminished
    when both spouses are participants in the crime,"           
    Clark, 712 F.2d at 301
    (citing Van 
    Drunen, 501 F.2d at 1397
    ), we note that
    "rehabilitation ha[s] never been regarded as one of the interests
    served by the spousal privilege."           In re Grand Jury 
    Subpoena, 755 F.2d at 1026
    .       Even if we were to accept that rehabilitation is
    one of the privilege's underlying rationales, we do not find it to
    -26-
    be necessarily true in all cases that a marriage in which the
    spouses are parties to a criminal conspiracy prevents that marriage
    from being one that would aid in rehabilitation.                 At the very
    least, the uncertainty surrounding this principle persuades us
    that the best course in this case is to decline the Government's
    invitation to recognize the joint participant exception.
    Notably,     the    Government    fails   to   address   how   the
    exception it seeks is consistent with the broader societal interest
    behind the spousal testimonial privilege in avoiding the perceived
    unseemliness     of    seeing   a    spouse   being   coerced   to   actively
    contribute to the prosecution of his or her spouse.             Even in cases
    where the married couple is, in fact, using the marriage as a
    shield to hide joint criminal activity and "abus[ing] the marital
    privilege granted to them by the state," it is not apparent that
    the broader concern about the appearance of the Government coercing
    one spouse to testify against the other applies with any less
    force.
    Accordingly, the Rule 501 balancing analysis weighs in
    favor of rejecting the joint participant exception.
    C.
    The Government suggests two additional reasons why it
    believes it would be appropriate to recognize a joint participant
    exception   to   the    spousal     testimonial   privilege.      First,   the
    -27-
    Government presents this case as an opportunity to "unify the law
    governing the marital privileges," noting that every federal court
    of appeals "has adopted a joint participant exception to the
    martial communications privilege."            Because both privileges are
    rooted in the policy of promoting marital harmony, the Government
    urges, "the outcome of the Rule 501 balance in the conspiracy
    context should also be the same" for both privileges.
    However, the importance of distinguishing between these
    two privileges is evident in several respects, not least of which
    is the manner in which each operates.          The marital communications
    privilege can be asserted by both spouses, see United States v.
    Picciandra, 
    788 F.2d 39
    , 43 (1st Cir. 1986) (noting that the
    marital   communications     privilege     "prohibits      one   spouse   from
    adversely testifying to confidential communications made by the
    other during their marriage"), in order to "ensur[e] that spouses
    . . . feel free to communicate their deepest feelings to each other
    without fear of eventual exposure in a court of law."             
    Breton, 740 F.3d at 10
    (quoting United States v. Brock, 
    724 F.3d 817
    , 820–21
    (7th   Cir.    2013)   (citation   omitted)    (internal    quotation     marks
    omitted)).      The spousal testimonial privilege, by contrast, can
    only be asserted by the testifying spouse, see 
    Trammel, 445 U.S. at 53
    , in order to protect him or herself from taking the witness
    stand at all.     See 
    Trammel, 445 U.S. at 51
    (noting that the spousal
    -28-
    testimonial privilege's "protection is not limited to confidential
    communications.").         This is important because the universe of
    testimony that a joint participant exception would make available
    to the Government (where it otherwise would not be) is smaller and
    narrower for the marital communications privilege than for the
    spousal testimonial privilege.         Thus, invoking a joint participant
    exception to the spousal testimonial privilege would allow the
    prosecutor to force the spouse to take the stand and make available
    not only marital communications, but also a panoply of other
    information -- the revealing of which may be detrimental to
    marriage.
    Furthermore, the joint participant exception to the
    marital communications privilege is arguably less pernicious to
    marital harmony than an equivalent abrogation of the spousal
    testimonial privilege.         To be sure, the Government's presentation
    of communications between two spouses may very well be harmful to
    the relationship.         But, unlike when a prosecutor enters evidence
    consisting     of    marital    communications,       piercing    the    spousal
    testimonial     privilege      necessarily   involves        coercing    a     non-
    defendant spouse to take the witness stand, face his or her spouse,
    and put the nails in the defendant spouse's proverbial coffin.
    Such a display undoubtedly also raises the unseemly spectre that
    "undermine[s]       the   marriage   precisely   in    the   manner     that   the
    -29-
    privilege is designed to prevent."

    The second argument offered by the Government is that
    the    already-established        injured       spouse   exception 8 demonstrates
    that    the   Trammel      decision       "does   not    mean    that    the    spousal
    testimonial         privilege    is   a    privilege      that       should    have   no
    exceptions."        The Government goes on to emphasize that in Breton,
    we found that "the injured spouse exception is warranted, in part,
    because of the peculiar need for evidence in cases involving
    spouse-on-spouse or spouse-on-child crime."                     But, assuming as we
    do that the underlying purpose behind the injured-spouse exception
    is to protect the family, Wyatt v. United States, 
    362 U.S. 525
    ,
    529 (1960), it is difficult to see how that rationale has any
    application to the joint participant exception the Government asks
    us to adopt.         All that this argument does for the Government is

    to persuade us that the balance weighs in favor of recognizing the

    For    all   the   foregoing        reasons,      we    find    that    the
    Government's interest in having the ability to compel the testimony

    of   a   defendant's    co-conspiring   spouse   are   outweighed   by   the
    significant policy concerns underlying the spousal testimonial
    privilege.     This time-honored evidentiary privilege is no less
    deserving of protection when the witness whose testimony it seeks
    to compel is alleged to be a co-conspirator than when he or she is
    not.     We therefore join the majority of our sister circuits that
    have considered this issue and conclude that the balance of
    interests mandated by Rule 501 weighs against recognizing the joint
    participant exception to the spousal testimonial privilege.              The
    district court, therefore, did not abuse its discretion in denying
    the Government's motion to compel Guerrero to testify against her
    husband,     and   in    granting   Guerrero's   motion    to    quash   the
    Government's subpoena.
    We note, however, that our decision today does not
    foreclose the possibility of a defendant's co-conspirator spouse
    taking the stand to testify against the defendant in a conspiracy
    case.     As it often does in co-conspirator cases, the Government
    remains free to attempt to persuade a defendant's co-conspirator
    spouse to testify voluntarily against their defendant spouse.            We
    hold only that the Government cannot compel the non-defendant
    spouse's     testimony     in   conspiracy   prosecutions       absent   the
    availability of another exception to this privilege.
    For these reasons, the decision of the district court is
