    Rush, Chief Justice.
    When Katelin Seo was placed under arrest, law enforcement took her
    iPhone believing it contained incriminating evidence. A detective got a
    warrant to search the smartphone, but he couldn’t get into the locked
    device without Seo’s assistance. So the detective got a second warrant that
    ordered Seo to unlock her iPhone. She refused, and the trial court held her
    in contempt.
    We reverse the contempt order. Forcing Seo to unlock her iPhone
    would violate her Fifth Amendment right against self-incrimination. By
    unlocking her smartphone, Seo would provide law enforcement with
    information it does not already know, which the State could then use in its
    prosecution against her. The Fifth Amendment’s protection from
    compelled self-incrimination prohibits this result. We thus reverse and
    remand.
    Facts and Procedural History
    Katelin Seo contacted her local sheriff’s department claiming D.S. had
    raped her. Detective Bill Inglis met with Seo, and she told him that her
    smartphone—an iPhone 7 Plus—contained relevant communications with
    the accused. With Seo’s consent, officers completed a forensic download
    of the device and returned it.
    Based on the evidence recovered from the iPhone and the detective’s
    conversations with Seo, no charges were filed against D.S. Instead, law
    enforcement’s focus switched to Seo. D.S. told Detective Inglis that Seo
    stalked and harassed him, and the detective’s ensuing investigation
    confirmed those claims.
    Detective Inglis learned that Seo first contacted D.S. from the phone
    number associated with her iPhone. But D.S. then began receiving up to
    thirty calls or text messages daily from dozens of different, unassigned
    numbers. Yet, because the substance of the contact was consistent, the
    detective believed that Seo placed the calls and texts using an app or
    internet program to disguise her phone number. As a result of this
    Indiana Supreme Court | Case No. 18S-CR-595 | June 23, 2020       Page 2 of 18
    investigation, the State charged Seo with several offenses and issued an
    arrest warrant.
    When Detective Inglis arrested Seo, he took possession of her locked
    iPhone. Officers asked Seo for the device’s password, but she refused to
    provide it. To clear this hurdle, Detective Inglis obtained two search
    warrants. The first authorized a forensic download of Seo’s iPhone so that
    law enforcement could search the device for “incriminating evidence.”
    And the second “compelled” Seo to unlock the device and stated that she
    would be subject “to the contempt powers of the court” if she failed to do
    so. After Seo again refused to unlock her iPhone, the State moved to hold
    her in contempt.
    At the ensuing hearing, Seo argued that forcing her to unlock the
    iPhone would violate her Fifth Amendment right against self-
    incrimination. The trial court disagreed and held Seo in contempt,
    concluding that “[t]he act of unlocking the phone does not rise to the level
    of testimonial self-incrimination.” Seo appealed, and the trial court stayed
    its contempt order.
    While her appeal was pending, Seo entered into a plea agreement with
    the State. She pleaded guilty to one count of stalking, and the State
    dismissed eighteen other charged offenses without prejudice. But because
    the contempt citation remained in place, Seo still faced the threat of
    further sanction for disobeying that order. A divided panel of our Court of
    Appeals reversed the court’s pending contempt order. Seo v. State, 
    109 N.E.3d 418
    , 440–41 (Ind. Ct. App. 2018).
    We granted transfer, vacating the Court of Appeals decision. Ind.
    Appellate Rule 58(A). 1
    1Our dissenting colleagues are incorrect in finding this case moot, as there has not yet been “a
    settlement of all differences between the parties,” Gompers v. Buck’s Stove & Range Co., 
    221 U.S. 418
    , 451 (1911). Justice Massa asks, “What could the State now gain from Seo unlocking her
    device?” Post, at 3. But the State has already answered that question—to complete its
    investigation of Seo and potentially file additional charges. After pleading guilty, Seo filed a
    motion requesting that law enforcement return her iPhone—which has remained in police

    Standard of Review
    Seo’s challenge to the trial court’s contempt order alleges a
    constitutional violation, and thus our review is de novo. See Myers v. State,
    
    27 N.E.3d 1069
    , 1074 (Ind. 2015).
    Discussion and Decision
    The Fifth Amendment’s Self-Incrimination Clause protects a person
    from being “compelled in any criminal case to be a witness against
    himself.” U.S. Const. amend. V. Embedded within this constitutional
    principle is the requirement that the State produce evidence against an
    individual through “the independent labor of its officers, not by the
    simple, cruel expedient of forcing it from his own lips.” Estelle v. Smith,
    
    451 U.S. 454
    , 462 (1981) (cleaned up). The privilege thus protects an
    accused from being forced to provide the State with even a link in the
    chain of evidence needed for prosecution. See Hoffman v. United States, 
    341 U.S. 479
    , 486 (1951). Yet, not all compelled, incriminating evidence falls
    under this constitutional protection: the evidence must also be testimonial.
    Hiibel v. Sixth Judicial Dist. Court of Nev., Humboldt Cty., 
    542 U.S. 177
    , 189
    (2004).
    custody since it was seized—because she had “no pending criminal cases.” The State objected,
    and during a hearing on the motion, the State clarified that its interest in accessing Seo’s
    iPhone is “not limited” to just the charges covered by the plea agreement. The prosecutor
    explained that the State could not “do a full investigation” or “be in a position to either not
    bring or choose to bring new cases” until it had evidence from the device. Then at oral
    argument, the State not only reiterated its continued interest in searching Seo’s iPhone but
    also argued that the case was not moot because the “threat of a sanction still hangs over
    [Seo’s] head.” So, contrary to the dissenting view, the State has not settled all claims with Seo;
    and the stayed contempt order has not automatically terminated. See Pac. Bell Tel. Co. v.
    Linkline Commc’ns, Inc., 
    555 U.S. 438
    , 446–47 (2009) (recognizing that a case is not moot when
    there “remains a live dispute”); United States v. Harris, 
    582 F.3d 512
    , 516 (3d Cir. 2009) (finding
    that the termination of underlying criminal proceedings did not render a coercive civil
    contempt order moot when the purpose and intent of the order “remain alive and well”). In
    short, this case presents a live dispute and thus our decision renders effective relief. But
    irrespective of mootness, this case presents a novel, important issue of great public
    importance that will surely recur.
    Indiana Supreme Court | Case No. 18S-CR-595 | June 23, 2020                            Page 4 of 18
    To be testimonial, “an accused’s communication must itself, explicitly
    or implicitly, relate a factual assertion or disclose information.” Doe v.
    United States, 
    487 U.S. 201
    , 210 (1988). The most common form of
    testimony is verbal or written communications—the vast amount of which
    will fall within the privilege. 
    Id.
     at 213–14. But physical acts can also have
    a testimonial aspect. See Fisher v. United States, 
    425 U.S. 391
    , 410 (1976).
    When the State compels a suspect to produce physical evidence, that
    act is testimonial if it implicitly conveys information. See United States v.
    Hubbell, 
    530 U.S. 27
    , 36 (2000); Pennsylvania v. Muniz, 
    496 U.S. 582
    , 595 n.9
    (1990). In certain contexts, however, the communicative aspects of the act
    may be rendered nontestimonial if the State can show that it already
    knows the information conveyed, making it a “foregone conclusion.”
    Fisher, 
    425 U.S. at 411
    . In other words, the inquiry is whether the
    testimonial communications implicit in producing the evidence provide
    the State with something it does not already know.
    Here, Seo argues that the State, by forcing her to unlock her iPhone for
    law enforcement, is requiring her to “assist in the prosecution of her own
    criminal case” and thus violating her right against self-incrimination. The
    State disagrees, claiming it already knows the implicit factual information
    Seo would convey by unlocking her iPhone—namely, that she “knows the
    password and thus has control and use of the phone.”
    We agree with Seo. The compelled production of an unlocked
    smartphone is testimonial and entitled to Fifth Amendment protection—
    unless the State demonstrates the foregone conclusion exception applies.
    Here, the State has failed to make that showing; and this case also
    highlights concerns with extending the limited exception to this context.
    I. The act of producing an unlocked smartphone
    communicates a breadth of factual information.
    Giving law enforcement an unlocked smartphone communicates to the
    State, at a minimum, that (1) the suspect knows the password; (2) the files
    on the device exist; and (3) the suspect possesses those files. This broad
    spectrum of communication is entitled to Fifth Amendment protection
    Indiana Supreme Court | Case No. 18S-CR-595 | June 23, 2020          Page 5 of 18
    unless the State can show that it already knows this information, making
    it a foregone conclusion. We make these determinations after carefully
    reviewing the U.S. Supreme Court precedent that has created and
    evaluated both the act of production doctrine and its accompanying
    foregone conclusion exception.
    Our starting point is Fisher v. United States, 
    425 U.S. 391
     (1976). There,
    the IRS subpoenaed several taxpayers’ documents that accountants
    prepared and the taxpayers’ attorneys possessed. 
    Id.
     at 394–96. The
    attorneys responded that complying with the subpoenas would violate
    their clients’ rights against self-incrimination. 
    Id.
     at 395–96. 2 The Court
    disagreed. 
    Id. at 414
    .
    In reaching that conclusion, Fisher considered what, if any,
    incriminating testimony would be compelled by responding to a
    documentary summons. 
    Id. at 409
    . It was here that the Court created the
    act of production doctrine: producing documents in response to a
    subpoena can be testimonial if the act concedes the existence, possession,
    or authenticity of the documents ultimately produced. 
    Id. at 410
    . But when
    the government can show that it already knows this information, then the
    testimonial aspects of the act are a “foregone conclusion,” 
    id. at 411
    , and
    complying with the subpoena becomes a question “not of testimony but of
    surrender,” 
    id.
     (quoting In re Harris, 
    221 U.S. 274
    , 279 (1911)). This was the
    situation in Fisher—the Government knew who possessed the tax
    documents, and it could independently confirm the documents’ existence
    and authenticity through the accountants who prepared them. 
    Id.
     at 412–
    13. So, the Court narrowly held that “compliance with a summons
    directing the taxpayer to produce the accountant’s documents involved in
    2 Fisher recognized that compelling the attorneys to hand over the documents did not
    “implicate whatever Fifth Amendment privilege the taxpayer might have enjoyed from being
    compelled to produce them himself.” 
    425 U.S. at 402
    . But because the taxpayers had
    transferred the documents for legal advice protected by the attorney–client privilege, 
    id.
     at
    403–04, the Court addressed whether the Government could have compelled the taxpayers
    themselves to produce the documents, 
    id. at 405
    .
    Indiana Supreme Court | Case No. 18S-CR-595 | June 23, 2020                       Page 6 of 18
    these cases” did not implicate incriminating testimony within the Fifth
    Amendment’s protection. 
    Id. at 414
    .
    Fisher was the first, and only, Supreme Court decision to find that the
    testimony implicit in an act of production was a foregone conclusion. In
    contrast, the government failed to make that showing in the other two
    relevant decisions: United States v. Doe, 
    465 U.S. 605
     (1984) (Doe I) and
    United States v. Hubbell, 
    530 U.S. 27
     (2000).
    In Doe I, the Government served five subpoenas commanding a
    business owner to produce certain documents. 
    465 U.S. at
    606–07. He
    refused, arguing that complying with the subpoenas would violate his
    right against self-incrimination. 
    Id.
     at 607–08. The District Court agreed,
    finding that compliance would compel the business owner “to admit that
    the records exist, that they are in his possession, and that they are
    authentic.” 
    Id.
     at 613 & n.11.
    The Doe I Court affirmed the District Court’s finding “that the act of
    producing documents would involve testimonial self-incrimination.” 
    Id.
     at
    613–14. The Court then explained that the Government was not foreclosed
    from producing “evidence that possession, existence, and authentication
    were a ‘foregone conclusion,’” but that it had “failed to make such a
    showing.” 
    Id.
     at 614 n.13 (quoting Fisher, 
    425 U.S. at 411
    ).
    Similarly, the Court in Hubbell found that the foregone conclusion
    exception did not apply. 
    530 U.S. at 44
    . There, the Government served a
    subpoena requesting a vast array of documents. 
    Id. at 31
    . In response,
    Hubbell produced 13,120 pages; and he was later indicted based on
    information gleaned from their contents. 
    Id.
     In finding that Hubbell’s
    compliance with the subpoena violated his right against self-
    incrimination, the Court rejected two of the Government’s arguments.
    Hubbell first refused to equate the physical act of handing over the
    documents with the testimony implicit in the act. 
    Id.
     at 40–41. The Court
    agreed that the testimonial aspect of responding to a documentary
    summons “does nothing more than establish the existence, authenticity,
    and custody of items that are produced.” 
    Id.
     But it rebuffed the
    Government’s “anemic view” of the act of production as a “simple
    Indiana Supreme Court | Case No. 18S-CR-595 | June 23, 2020        Page 7 of 18
    physical act.” 
    Id. at 43
    . The Court explained that a physical act,
    nontestimonial in character, cannot be “entirely divorced from its
    ‘implicit’ testimonial aspect.” 
    Id.
    Hubbell also rejected the Government’s argument that, under Fisher,
    “the existence and possession of such records by any businessman is a
    ‘foregone conclusion.’” 
    Id. at 44
    . The Court referred to Fisher’s unique
    context and explained, “Whatever the scope of this ‘foregone conclusion’
    rationale, the facts of this case plainly fall outside of it.” 
    Id.
     Unlike in
    Fisher, the Hubbell Court reasoned that, because the Government failed to
    show “it had any prior knowledge of either the existence or the
    whereabouts of the . . . documents ultimately produced,” the foregone
    conclusion exception did not apply. 
    Id. at 45
    .
    Fisher, Doe I, and Hubbell establish that the act of producing documents
    implicitly communicates that the documents can be physically produced,
    exist, are in the suspect’s possession, and are authentic. And this trilogy of
    Supreme Court precedent further confirms that the foregone conclusion
    exception must consider these broad communicative aspects. See
    Commonwealth v. Davis, 
    220 A.3d 534
    , 547 (Pa. 2019) (recognizing that “the
    Supreme Court has made, and continues to make, a distinction between
    physical production and testimonial production”), petition for cert. filed
    (U.S. Apr. 20, 2020) (No. 19-1254).
    In this way, the act of production doctrine links the physical act to the
    documents ultimately produced. See Laurent Sacharoff, What Am I Really
    Saying When I Open My Smartphone? A Response to Orin S. Kerr, 97 Tex. L.
    Rev. Online 63, 68 (2019). And the foregone conclusion exception relies on
    this link by asking whether the government can show it already knows
    the documents exist, are in the suspect’s possession, and are authentic. 
    Id.
    True, the documents’ contents are not protected by the Fifth Amendment
    because the government did not compel their creation. See Doe I, 
    465 U.S. at
    611–12; Fisher, 
    425 U.S. at
    409–10. But the specific documents
    “ultimately produced” implicitly communicate factual assertions solely
    through their production. See Hubbell, 
    530 U.S. at
    36 & n.19, 45.
    When extending these observations to the act of producing an unlocked
    smartphone, we draw two analogies. First, entering the password to
    Indiana Supreme Court | Case No. 18S-CR-595 | June 23, 2020          Page 8 of 18
    unlock the device is analogous to the physical act of handing over
    documents. Sacharoff, supra, at 68. And second, the files on the
    smartphone are analogous to the documents ultimately produced. Id.
    Thus, a suspect surrendering an unlocked smartphone implicitly
    communicates, at a minimum, three things: (1) the suspect knows the
    password; (2) the files on the device exist; and (3) the suspect possessed
    those files. 3 And, unless the State can show it already knows this
    information, the communicative aspects of the production fall within the
    Fifth Amendment’s protection. Otherwise, the suspect’s compelled act
    will communicate to the State information it did not previously know—
    precisely what the privilege against self-incrimination is designed to
    prevent. See Couch v. United States, 
    409 U.S. 322
    , 328 (1973).
    This leads us to the following inquiry: has the State shown that (1) Seo
    knows the password for her iPhone; (2) the files on the device exist; and
    (3) she possessed those files?
    II. The foregone conclusion exception does not apply.
    As discussed above, compelling Seo to unlock her iPhone would
    implicitly communicate certain facts to the State. And for those
    communicative aspects to be rendered nontestimonial, the State must
    establish that it already knows those facts.
    Even if we assume the State has shown that Seo knows the password
    to her smartphone, the State has failed to demonstrate that any particular
    3 The majority of courts to address the scope of testimony implicated when a suspect is
    compelled to produce an unlocked smartphone have reached a similar conclusion. See State v.

    files on the device exist or that she possessed those files. Detective Inglis
    simply confirmed that he would be fishing for “incriminating evidence”
    from the device. He believed Seo—to carry out the alleged crimes—was
    using an application or internet program to disguise her phone number.
    Yet, the detective’s own testimony confirms that he didn’t know which
    applications or files he was searching for:
    There are numerous, and there’s probably some that I’m not
    even aware of, numerous entities out there like Google Voice
    and Pinger and Text Now and Text Me, and I don’t know, I
    don’t have an all-encompassing list of them, however if I had
    the phone I could see which ones she had accessed through
    Google.
    In sum, law enforcement sought to compel Seo to unlock her iPhone
    so that it could then scour the device for incriminating information. And
    Seo’s act of producing her unlocked smartphone would provide the State
    with information that it does not already know. But, as we’ve explained
    above, the Fifth Amendment’s privilege against compulsory self-
    incrimination prohibits such a result. Indeed, to hold otherwise would
    sound “the death knell for a constitutional protection against compelled
    self-incrimination in the digital age.” Commonwealth v. Jones, 
    117 N.E.3d 702
    , 724 (Mass. 2019) (Lenk, J., concurring); see also Davis, 220 A.3d at 549
    (“[T]o apply the foregone conclusion rationale in these circumstances
    would allow the exception to swallow the constitutional privilege.”).
    Though the foregone conclusion exception does not apply to these
    facts, this case underscores several reasons why the narrow exception may
    be generally unsuitable to the compelled production of any unlocked
    smartphone. We discuss three concerns below.
    Indiana Supreme Court | Case No. 18S-CR-595 | June 23, 2020          Page 10 of 18
    III. This case highlights concerns with extending the
    limited foregone conclusion exception to the
    compelled production of an unlocked smartphone.
    Extending the foregone conclusion exception to the compelled
    production of an unlocked smartphone is concerning for three reasons:
    such an expansion (1) fails to account for the unique ubiquity and capacity
    of smartphones; (2) may prove unworkable; and (3) runs counter to U.S.
    Supreme Court precedent. We address each in turn.
    A. The compelled production of an unlocked smartphone
    is unlike the compelled production of specific business
    documents.
    Smartphones are everywhere and contain everything. They have
    become such “a pervasive and insistent part of daily life that the
    proverbial visitor from Mars might conclude they were an important
    feature of human anatomy.” Riley v. California, 
    573 U.S. 373
    , 385 (2014); see
    also City of Ontario v. Quon, 
    560 U.S. 746
    , 760 (2010). Indeed, a 2019 report
    from the Pew Research Center revealed that 81% of Americans own a
    smartphone, up from 35% in 2011. 4 The Supreme Court in Fisher (1976),
    Doe I (1984), or Hubbell (2000) surely could not have anticipated that such
    devices would become so common or imagined the breadth and depth of
    information they could contain.
    Notably, in each of those cases, a subpoena confined the information
    implicated by the compelled production. See Hubbell, 
    530 U.S. at
    45–46;
    Doe I, 
    465 U.S. at
    606–07, 607 nn.1–2; Fisher, 
    425 U.S. at
    394–95, 394 nn.2–3.
    Fisher acknowledged this limited scope, stating that the subpoenas there
    sought “documents of unquestionable relevance to the tax investigation,”
    but that “[s]pecial problems of privacy . . . might be presented by
    subpoena of a personal diary.”

    Acevedo, 
    169 F.3d 1155
    , 1167–68 (8th Cir. 1999) (en banc) (discussing the
    circuit split as to whether personal diaries can be subpoenaed); Samuel A.
    Alito, Jr., Documents and the Privilege Against Self-Incrimination, 
    48 U. Pitt. L. Rev. 27
    , 81 (1986) (opining that “certain types of highly private
    documents probably should not be obtainable by subpoena, regardless of
    whether they are self-incriminating”). And the Doe I Court remarked that
    the compelled documents, which “pertained to respondent’s businesses,”
    were less personal than those sought in Fisher, which “related to the
    taxpayers’ individual tax returns.” Doe I, 
    465 U.S. at
    610 n.7. An unlocked
    smartphone, however, contains far more private information than a
    personal diary or an individual tax return ever could. Yet, when suspects
    are compelled to surrender their unlocked smartphones, there is no limiter
    like a documentary subpoena for specific files. See, e.g., United States v.
    Bishop, 
    910 F.3d 335
    , 336 (7th Cir. 2018), cert. denied, 
    139 S. Ct. 1590
     (2019).
    Hubbell further illustrates the considerable difference between
    complying with a court order to produce an unlocked smartphone and
    complying with a documentary summons. Recall that, in Hubbell, the
    Government had not shown that it had any prior knowledge of either the
    existence or location of 13,120 pages of documents. 
    530 U.S. at 45
    . Though
    not an insignificant amount of information, it pales in comparison to what
    can be stored on today’s smartphones. Indeed, the cheapest model of last
    year’s top-selling smartphone, with a capacity of 64 gigabytes of data, can
    hold over 4,000,000 pages of documents—more than 300 times the number
    of pages produced in Hubbell. 5 It is no exaggeration to describe a
    smartphone’s passcode as “the proverbial ‘key to a man’s kingdom.’”

    This brings us to a second concern with extending the foregone
    conclusion exception—it may prove unworkable in this context.
    B. Extending the foregone conclusion exception to the
    compelled production of a smartphone may prove
    unworkable.
    Today’s smartphones “could just as easily be called cameras, video
    players, rolodexes, calendars, tape recorders, libraries, diaries, albums,
    televisions, maps, or newspapers.” Riley, 573 U.S. at 393. And they can
    contain, in digital form, the “combined footprint of what has been
    occurring socially, economically, personally, psychologically, spiritually
    and sometimes even sexually, in the owner’s life.” Djibo, 151 F. Supp. 3d at
    310.
    Recognizing these realities, several courts have determined that the
    government—prior to compelling a suspect to unlock their smartphone—
    must specifically identify the files it seeks with reasonable particularity. 6
    But even then, the government should have access to only those files. Yet,
    compelling the production of an unlocked smartphone gives the
    government access to everything on the device, not just those files it can
    identify with “reasonable particularity.” For example, here, even if the
    State could show that it knew of and could identify specific files on Seo’s
    iPhone, there is nothing to restrict law enforcement’s access to only that
    6See In re Application for a Search Warrant, 236 F. Supp. 3d at 1068, 1072–74; Trant,

    82. And several courts evaluating this issue in the context of other electronic devices, such as
    computers or hard drives, have similarly required the government to identify the information
    sought with reasonable particularity. See In re Grand Jury Subpoena Duces Tecum Dated Mar. 25,

    information. After all, the warrant authorized a search of Seo’s device
    without limitation.
    Such unbridled access to potential evidence on her iPhone—or any
    smartphone—raises several complex questions. For example, if officers
    searching a suspect’s smartphone encounter an application or website
    protected by another password, will they need a separate motion to
    compel the suspect to unlock that application or website? And would the
    foregone conclusion exception apply to that act of production as well?
    Suppose law enforcement opens an application or website and the
    password populates automatically. Can officers legally access that
    information? Or what if a suspect has a cloud-storage service—like iCloud
    or Dropbox—installed on the device, which could contain hundreds of
    thousands of files. Can law enforcement look at those documents, even
    though this windfall would be equivalent to identifying the location of a
    locked storage facility that officers did not already know existed? Such
    complexity is neither necessary nor surprising: the foregone conclusion
    exception is, in this context, a low-tech peg in a cutting-edge hole.
    This leads to a third concern with extending the foregone conclusion
    exception—it seems imprudent in light of recent Supreme Court
    precedent concerning smartphones and the limited, questionable
    application of the exception.
    C. U.S. Supreme Court precedent and the foregone
    conclusion exception’s limited application counsel
    against extending it further.
    The Supreme Court has hesitated to apply even entrenched doctrines to
    novel dilemmas, wholly unforeseen when those doctrines were created.
    Indeed, the Court recently observed that, when “confronting new
    concerns wrought by digital technology,” it “has been careful not to
    uncritically extend existing precedents.” Carpenter v. United States, 
    138 S. Ct. 2206
    , 2222 (2018). To that point, four years earlier, in Riley, the Court
    held that the search-incident-to-arrest exception to the warrant
    requirement does not extend to a cell phone found on an arrestee. 573 U.S.
    at 401–02. And in Carpenter, the Court held that the third-party doctrine
    Indiana Supreme Court | Case No. 18S-CR-595 | June 23, 2020        Page 14 of 18
    does not extend to cellular site location information, at least when seven
    days’ worth of data is obtained. 
    138 S. Ct. at
    2217 & n.3. The Supreme
    Court’s refusal to extend these two established doctrines—each far more
    deeply rooted than the foregone conclusion exception—is instructive.
    Though Riley and Carpenter were decided under the Fourth
    Amendment, the Court’s concern in each case was with the “privacy
    interests” implicated by smartphones. Riley, 573 U.S. at 397; Carpenter, 
    138 S. Ct. at
    2214–15. And that privacy concern likewise applies to the Fifth
    Amendment’s privilege against self-incrimination. Even though this
    privilege is not “a general protector of privacy,” Fisher recognized that it
    “truly serves privacy interests” by protecting suspects from being
    compelled to provide private, self-incriminating testimony. 
    425 U.S. at 399, 401
    ; see also 
    id.
     at 416–17 (Brennan, J., concurring in the judgment)
    (“Expressions are legion in opinions of this Court that the protection of
    personal privacy is a central purpose of the privilege against compelled
    self-incrimination.”); Murphy v. Waterfront Comm’n of N.Y. Harbor, 
    378 U.S. 52
    , 55 (1964); In re Grand Jury Proceedings, 
    632 F.2d 1033
    , 1042–44 (3d Cir.
    1980).
    The limited, and questionable, application of the foregone conclusion
    exception also cautions against extending it further. Indeed, Fisher was
    decided over forty-four years ago, and it remains the lone U.S. Supreme
    Court decision to find that the exception applied. In the intervening years,
    the Court has discussed it twice and in only one context: in grand jury
    proceedings when a subpoena compelled the production of business and
    financial records. During this same time period, legal scholars—including
    three current members of the Supreme Court—have wondered whether
    Fisher interpreted the Fifth Amendment too narrowly, calling into
    question the viability of the foregone conclusion exception itself. See
    Hubbell, 
    530 U.S. at
    49–56 (Thomas, J., concurring); Carpenter, 
    138 S. Ct. at 2271
     (Gorsuch, J., dissenting); Alito, Jr., supra, at 45–51; see also, e.g., Bryan
    H. Choi, The Privilege Against Cellphone Incrimination, 97 Tex. L. Rev.

    Witness” and the Resurrection of Boyd, 
    74 N.Y.U. L. Rev. 1575
    , 1606 &
    nn.124–25 (1999); Robert Heidt, The Fifth Amendment Privilege and
    Documents—Cutting Fisher’s Tangled Line, 
    49 Mo. L. Rev. 439

    Regardless of the foregone conclusion exception’s viability, it seems
    imprudent to extend it beyond its one-time application. Cf. Silverman v.
    United States, 
    365 U.S. 505
    , 510, 512 (1961) (deciding not to extend the
    rationale of a factually distinct case “by even a fraction of an inch”).
    It is not surprising that courts to recently address this issue—how the
    Fifth Amendment applies to the compelled production of unlocked
    electronic devices—have either declined to extend the foregone conclusion
    exception or have not mentioned it at all. 7 Not only was the exception
    crafted for a vastly different context, but extending it further would mean
    expanding a decades-old and narrowly defined legal exception to
    dynamically developing technology that was in its infancy just a decade
    ago. And it would also result in narrowing a constitutional right. Yet,
    while we have identified three concerns with extending the foregone
    conclusion exception to this context, we do not need to make a general
    pronouncement on its validity because it simply does not apply here.
    At the same time, we emphasize that there are several ways law
    enforcement can procure evidence from smartphones without infringing
    on an individual’s Fifth Amendment rights. For example, officers could
    try to obtain information from third parties under the Stored
    Communications Act. See 18 U.S.C. 121 §§ 2701–2713 (2018). Alternatively,
    two companies—Cellebrite and Grayshift—offer law enforcement
    agencies affordable products that provide access to a locked smartphone.
    See generally, e.g., United States v. Chavez-Lopez, 767 F. App’x 431, 433–34
    (4th Cir. 2019). Or officers could seek an order compelling the
    smartphone’s manufacturer to help bypass the lock screen. See In re XXX,
    Inc., No. 14 Mag. 2258, 
    2014 WL 5510865
     (S.D.N.Y. Oct. 31, 2014). And if
    law enforcement wants to get into a smartphone for reasons other than
    prosecution, they can offer immunity to the device’s owner. See Doe I, 
    465 U.S. at
    614–15. But the State cannot fish for incriminating evidence by
    forcing Seo to give unfettered access to her iPhone when it has failed to
    7See United States v. Jimenez, 
    419 F. Supp. 3d 232
    , 233 (D. Mass. 2020); Wright, 431 F. Supp. 3d
    at 1186–88; In re Residence in Oakland, 354 F. Supp. 3d at 1016–18; Davis, 220 A.3d at 550.
    Indiana Supreme Court | Case No. 18S-CR-595 | June 23, 2020                          Page 16 of 18
    show that any files on Seo’s smartphone exist or that she possessed those
    files.
    Nearly a century ago, U.S. Supreme Court Justice Louis Brandeis
    cautioned, “Ways may some day be developed by which the government,
    without removing papers from secret drawers, can reproduce them in
    court, and by which it will be enabled to expose to a jury the most
    intimate occurrences of the home.” Olmstead v. United States, 
    277 U.S. 438
    ,
    474 (1928) (Brandeis, J., dissenting). That day has come. And to allow the
    State, on these facts, to force Seo to unlock her iPhone for law enforcement
    would tip the scales too far in the State’s favor, resulting in a seismic
    erosion of the Fifth Amendment’s privilege against self-incrimination.
    This we will not do.
    Conclusion
    Forcing Seo to unlock her iPhone for law enforcement would violate
    her Fifth Amendment right against self-incrimination. We thus reverse the
    trial court’s order finding Seo in contempt and instruct the court to
    dismiss the citation.

    Massa, J., dissenting.
    I respectfully dissent from the Court’s opinion deciding the merits of
    this case because it was mooted when the underlying criminal case was
    dismissed. And this now-moot case shouldn’t be resolved under our
    “great public interest” exception because doing so could—in violation of
    the core principles of federalism—leave our Court as the final arbiter of
    our nation’s fundamental law.
    The gist of Seo’s purported behavior over the summer and fall of 2017
    is this: starting in June, Seo unrelentingly implored a man to either marry
    or impregnate her. In July, Seo started following and sending troubling
    messages to a woman who reported her to a supervisor for showing a
    horror film to the woman’s preschool children at the daycare where Seo
    worked. Seo was charged with various crimes in numerous cases for these
    interactions, and, on August 8, the trial court ordered Seo to unlock her
    iPhone to obtain evidence for a case involving the man, warning that her
    refusal could subject her to being held in contempt. On September 22,
    after she persistently refused to unlock the device, the trial court held Seo
    in contempt and ordered her incarcerated if she didn’t comply by the end
    of the day. Three days later, however, the court stayed the order after Seo
    indicated she would appeal it.
    The next July, Seo and the prosecution reached a global agreement: the
    State dismissed all other charges against Seo when she pleaded guilty to a
    single stalking charge involving the woman. All the charges in the cases
    involving the man—including those in the case where Seo was held in
    contempt for refusing to unlock her device—were dismissed. The next
    month, our Court of Appeals reversed the contempt order. Later yet, the
    State successfully opposed Seo’s request for the return of her device
    pending our resolution of the case.
    At the outset, we shouldn’t reach Seo’s constitutional claim because she
    is impermissibly waging a collateral attack on the trial court’s August 8
    order (compelling her to unlock her phone) through this appeal of the trial
    court’s September 22 order (holding her in contempt). “Collateral attack of
    a previous order is allowed in a contempt proceeding only if the trial court
    lacked subject matter or personal jurisdiction to enter the order.” State v.
    Combs, 
    921 N.E.2d 846
    , 851 (Ind. Ct. App. 2010) (quotation omitted).
    Because no one doubts the jurisdiction of the trial court here, and
    “[c]ontempt proceedings are not actions designed to correct errors
    previously made by trial courts,” 
    id.
     (quotation omitted), the Court
    shouldn’t permit Seo to challenge the constitutional validity of the trial
    court’s August 8 order through this appeal, see Clark v. Atkins, 
    489 N.E.2d 90
    , 96 (Ind. Ct. App. 1986) (explaining that even when “the questions
    raised concerning [an underlying] order are constitutional in nature,”
    contempt proceedings cannot be used for a collateral attack) (citation
    omitted). Although her Fifth Amendment right could potentially be
    “irretrievably lost” if she were to unlock her device now, Van
    Cauwenberghe v. Biard, 
    486 U.S. 517
    , 524 (1988) (citation omitted), we
    shouldn’t flout well-settled procedure to resolve Seo’s claim when she had
    forty-five days to file an interlocutory appeal of the August 8 order before
    being held in contempt. See Ind. Appellate Rule 14(B)(1)(c)(i) (permitting
    interlocutory appeal if a party believes she “will suffer substantial
    expense, damage[,] or injury if the order is erroneous and the
    determination of the error is withheld until after judgment.”).
    Nevertheless, this case is also moot. The Court, however, suggests it
    remains live because, as the State avows, “the ‘threat of a sanction still
    hangs over [Seo’s] head.’” Ante, at 4 n.1. But the order finding Seo in
    contempt was mooted—and this case was mooted—when Seo reached the
    agreement that, among other things, resolved the case underlying the
    order. “Contempts of court are classified as civil and criminal.” Perry v.
    Pernet, 
    165 Ind. 67
    , 70, 
    74 N.E. 609
    , 610 (1905). Criminal contempt cases
    survive even after an underlying cause is mooted because this contempt is
    “an act directed against the dignity and authority of the court which
    obstructs the administration of justice and which tends to bring the court
    into disrepute or disrespect.” State v. Heltzel, 
    552 N.E.2d 31
    , 34 (Ind. 1990).
    These contempt orders subsist, then, until a defendant “has served his
    contempt sentence and has been released.” Bell v. State, 
    1 N.E.3d 190
    , 192
    (Ind. Ct. App. 2013).
    But Seo’s contempt was civil: she refused “to do something which [s]he
    [wa]s ordered to do for the benefit or advantage of the opposite party.”
    Perry, 165 Ind. at 70, 74 N.E. at 610 (quotation omitted). Since the opposing
    Indiana Supreme Court | Case No. 18S-CR-595 | June 23, 2020           Page 2 of 9
    party “alone has an interest in the enforcement of” a civil contempt order,
    any associated punishment “terminates” the moment this party’s interest
    ceases. Id. at 71, 610. So when an underlying cause concludes by
    “settlement of all differences between the parties,” any attendant civil
    contempt proceeding “necessarily” ends. Gompers v. Buck's Stove & Range
    Co., 
    221 U.S. 418
    , 451–452 (1911).1 Here, the State reached a global
    settlement with Seo resolving the claims it had against her. Once these
    charges were settled, the civil contempt order automatically terminated.
    What could the State now gain from Seo unlocking her device?
    The Court contends “that the State could not ‘do a full investigation’ or
    ‘be in a position to either not bring or choose to bring new cases’ until it
    had evidence from the device.” Ante, at 4 n.1. But a year before opposing
    the return of Seo’s device, the State returned the search warrant,
    acknowledging that “this matter is now closed.” Return on Search
    Warrant, In Re: Search Warrant, No. 29D01-1708-MC-5624 (Hamilton Sup.
    Ct.); see 
    Ind. Code § 35-33-5-4
     (directing that, ordinarily, after a search
    warrant is executed, the executing officer must ensure a “return” of the
    warrant, stating the date and time of the search and what items were
    seized).2 Instead of retaining the search warrant for further investigation,
    the State returned it after having settled all claims with Seo. Despite its
    later assertion “that its interest in accessing Seo’s iPhone [wa]s ‘not

    2To be sure, the trial court granted, nearly simultaneously, two “search warrants” involving
    Seo’s cases, and this filing only “returned” the first. But in the request for the second, the State
    acknowledged that the trial court had already “issued a search warrant (cause number 29D01-
    1708-MC-5624)” for Seo’s phone and merely additionally requested “that the court compel
    Katelin Eunjoo Seo to unlock the cell phone at issue,” and that Seo “be subject to the contempt
    powers of the Court” if she failed to comply. Affidavit for Probable Cause, In Re: Search

    limited’ to just the charges covered by the plea agreement,” ante, at 4 n.1,
    the State should have, if it sought to trawl for further charges, awaited
    resolution of this appeal before settling the cases. But it didn’t, so this case
    can’t provide any relief “‘to the parties before the court.’” T.W. v. St.
    Vincent Hosp. & Health Care Ctr., Inc., 
    121 N.E.3d 1039
    , 1042 (Ind. 2019)
    (quoting Matter of Lawrance, 
    579 N.E.2d 32
    , 37 (Ind. 1991)). When “[n]one
    of the parties seem to have any interest left in the case,” this court of last
    resort should dismiss because it “ought not to be engaged in passing
    on moot-court questions.” State ex rel. Taylor v. Mount, 
    151 Ind. 679
    , 694, 
    52 N.E. 407
    , 407 (1898).
    But this Court has, for better or worse, decided moot cases “‘when the
    issue involves a question of great public importance which is likely to
    recur.’” T.W., 121 N.E.3d at 1042 (quoting Matter of Tina T., 
    579 N.E.2d 48
    ,
    54 (Ind. 1991)). Indeed, the Court acknowledges it believes that,
    “irrespective of mootness, this case presents a novel, important issue of
    great public importance that will surely recur.” Ante, at 4 n.1. Because,
    however, constitutional questions should be avoided unless answering
    them is “absolutely necessary to a disposition of the cause on its merits,”
    State v. Darlington, 
    153 Ind. 1
    , 4, 
    53 N.E. 925
    , 926 (1899), this Court
    should—in cases resolving federal questions—employ the Article-III-
    mirroring mootness test recently used by Senior Judge Shepard: whether
    “‘the issue concerns a question of great public importance which is likely
    to recur in a context which will continue to evade review,’” Liddle v. Clark,
    
    107 N.E.3d 478
    , 482 (Ind. Ct. App. 2018) (quoting DeSalle v. Gentry, 
    818 N.E.2d 40
    , 49 (Ind. Ct. App. 2004)) (emphasis added), trans. denied. To be
    sure, then-Chief Justice Shepard noted that this heightened standard “is a
    federal mootness doctrine, stricter than our own, rooted in the
    requirement that Article III courts decide only live cases and
    controversies.” Lawrance, 579 N.E.2d at 37 n.2. But Lawrance applied our
    relaxed standard when answering questions of Indiana law, not a federal
    Indiana Supreme Court | Case No. 18S-CR-595 | June 23, 2020            Page 4 of 9
    question that could be unreviewable, depending wholly on the prevailing
    party,3 by the U.S. Supreme Court.
    Although the issue in this case is clearly one of great public importance
    and will surely recur with other defendants, it will not evade review. Seo
    entered into a global agreement resolving the case tied to her contempt
    order before our Court of Appeals issued its opinion reversing the order
    holding her in contempt. But her resolution of the case before appellate
    review is the outlier, not the norm. Cf. Hartman v. State, 
    988 N.E.2d 785
    (Ind. 2013) (reversing under the Fifth Amendment—and in an
    interlocutory appeal—a trial court’s denial of a defendant’s motion to
    suppress). Perhaps we still exercise our lesser standard in cases like
    Lawrance involving only questions of Indiana law. Perhaps not. See Wallace
    v. City of Indianapolis, 
    40 Ind. 287
    , 289 (1872) (“It is not our duty to decide
    mere legal questions, when neither party can derive any legal benefit from
    such decision, and we have too many real questions before us, requiring
    our time and labor, to allow us to write mere speculative opinions to
    gratify ourselves or others, and in which no one has any legal right or
    interest depending.”). But that is a question for another day.
    Instead, we must ask whether this Court should use a federally moot
    case to decide an important question of federal constitutional law. The
    answer must be no. To be sure, “the constraints of Article III do not apply
    to state courts, and accordingly the state courts are not bound by the
    3 If state courts find in favor of, but not against, asserted federal rights for non-Article III
    litigants, opposing parties may seek Supreme Court review because they, in some way, “are
    faced with ‘actual or threatened injury’ that is sufficiently ‘distinct and palpable’ to support”
    justiciability. ASARCO Inc. v. Kadish, 
    490 U.S. 605
    , 618 (1989) (quoting Warth v. Seldin, 
    422 U.S. 490
    , 500 (1975). But this asymmetrical grant of appeal crumbles under scrutiny. Suppose this
    Court held, correctly in my view, that Seo’s Fifth Amendment rights were not violated. Under
    ASARCO, that holding—declining to clairvoyantly extend a criminal defendant’s federal
    rights—evades U.S. Supreme Court review. That peculiarity alone should counsel this Court
    against deciding federal questions “in the rarified atmosphere of a debating society,” 
    id. at 636
    (Rehnquist, C.J., concurring in part and dissenting in part), especially considering the
    Judiciary Act of 1789 authorized Supreme Court review of state court decisions only when the
    state court decided a federal question adversely to the claimed federal right, Judiciary Act of
    1789, ch. 20, § 25, 
    1 Stat. 73
    , 85–87 (1789).

    limitations of a case or controversy or other federal rules of justiciability
    even when they address issues of federal law, as when they are called
    upon to interpret the Constitution.” ASARCO Inc. v. Kadish, 
    490 U.S. 605
    ,
    617 (1989). But whether state courts entertain federal-law challenges
    absent Article III requirements “is entirely a matter of state law.” Virginia
    v. Hicks, 
    539 U.S. 113
     (2003). Our courts should not.
    Both the “the national and State [judicial] systems are to be regarded as
    ONE WHOLE,” with appeals from state courts interpreting federal laws
    naturally flowing “to that tribunal which is destined to unite and
    assimilate the principles of national justice and the rules of national
    decisions.” Federalist No. 82 (Alexander Hamilton). To Hamilton, all cases
    determining federal law “shall, for weighty public reasons, receive their
    original or final determination in the courts of the Union.” 
    Id.
     And the
    nascent Supreme Court agreed, noting that a chief purpose of its review
    over state court opinions deciding questions of federal constitutional law
    is the importance, and even necessity of uniformity of
    decisions throughout the whole United States, upon all subjects
    within the purview of the constitution. Judges of equal learning
    and integrity, in different states, might differently interpret a
    statute, or a treaty of the United States, or even the constitution
    itself: If there were no revising authority to control these jarring
    and discordant judgments, and harmonize them into
    uniformity, the laws, the treaties, and the constitution of the
    United States would be different in different states, and might,
    perhaps, never have precisely the same construction,
    obligation, or efficacy, in any two states. The public mischiefs
    that would attend such a state of things would be truly
    deplorable; and it cannot be believed that they could have
    escaped the enlightened convention which formed the
    constitution.
    Martin v. Hunter’s Lessee, 14 U.S. (1 Wheat.) 304, 347–48 (1816). To protect
    the “vital interest to the nation” it was—and is—“essential” that the U.S.
    Supreme Court exercise “appellate power over those judgments of the
    Indiana Supreme Court | Case No. 18S-CR-595 | June 23, 2020            Page 6 of 9
    State tribunals which may contravene the constitution or laws of the
    United States.” Cohens v. Virginia, 19 U.S. (6 Wheat.) 264, 414–15 (1821).
    “The judicial power of the United States is extended to all cases arising
    under the constitution.” Marbury v. Madison, 5 U.S. (1 Cranch) 137, 178
    (1803) (emphasis added). Irrefutably, the Supreme Court of the United
    States—not this state supreme court or any other—“is the final arbiter of
    federal law.” Danforth v. Minnesota, 
    552 U.S. 264
    , 291–92 (2008) (Roberts,
    C.J., dissenting). Rejecting the finality of that Court betrays a core first
    principle of this nation: when we decide issues of federal law by
    exercising a flexible exception that could divest a federal court of
    jurisdiction under its more-rigid Article III constraints, we usurp our role
    in this federal system, defenestrating the U.S. Supreme Court in the
    process. See Cohens, 19 U.S. (6 Wheat.) at 371 (“[T]he judicial control of the
    Union over State encroachments and usurpations, was indispensable to
    the sovereignty of the constitution—to its integrity—to its very existence.
    Take it away, and the Union becomes again a loose and feeble
    confederacy—a government of false and foolish confidence—a delusion
    and a mockery!”).
    Although “State courts are coequal parts of our national judicial system
    and give serious attention to their responsibilities for enforcing the
    commands of the Constitution,” Sawyer v. Smith, 
    497 U.S. 227
    , 241 (1990),
    this Court has long known “that the judicial power of the United States is
    extended, by the constitution, to all cases arising under the constitution,
    laws, and treaties of the United States,” Moyer v. McCullough, 
    1 Ind. 339
    ,
    343 (1849). Indeed, Justice Blackford noted, while state courts may enjoy
    primary jurisdiction over federal questions, the “constitution requires the
    jurisdiction in such cases to be extended to the federal Courts.” 
    Id.
     And
    this view isn’t constrained to the era immediately preceding the
    ratification of our 1851 constitution. Recently, for example—in a case
    unhampered by federal justiciability concerns—we chose to “await
    guidance from the Supreme Court and decline to find or assume [an issue
    of constitutional law] until the Supreme Court decides the issue
    authoritatively.” State v. Timbs, 
    84 N.E.3d 1179
    , 1183 (Ind. 2017), vacated
    and remanded. Noting that “Indiana is a sovereign state within our federal
    Indiana Supreme Court | Case No. 18S-CR-595 | June 23, 2020           Page 7 of 9
    system,”4 this Court unanimously avoided prematurely deciding an
    important question of federal law by declining to impose “federal
    obligations on the State that the federal government itself has not
    mandated.” 
    Id.
     at 1183–84; see also Sparks v. State, 
    499 N.E.2d 738
    , 741 (Ind.
    1986) (declining to divine “[w]hether a federal Fifth Amendment right to
    due process attaches to a state grand jury proceeding”). This bedrock
    principle does not change—it has never been, and never will be, our role
    to predict decisions by the U.S. Supreme Court.
    As Justice Jackson so famously proclaimed about the U.S. Supreme
    Court, “[w]e are not final because we are infallible, but we are infallible
    only because we are final.” Brown v. Allen, 
    344 U.S. 443
    , 540 (1953)
    (Jackson, J., concurring) (emphasis added). “What, indeed, might then
    have been only prophecy”—that our Court now firmly establishes that it
    will reject that finality by deciding cases that can bypass the revising
    authority of the U.S. Supreme Court on important questions of federal
    constitutional law—“has now become fact.” Martin, 14 U.S. (1 Wheat.) at
    348. By deciding this case, the Court’s message is crystal clear: it will
    anoint itself, at times, as the final adjudicator of federal law. To this, I
    cannot assent.
    And as for the adjudication of that federal law, this Fifth Amendment
    question is the closest of close calls. Courts around the country split,
    falling into two camps. See generally Orin S. Kerr, Compelled Decryption and
    the Privilege Against Self-Incrimination, 
    97 Tex. L. Rev. 767
     (2019); Laurent
    Sacharoff, What Am I Really Saying When I Open My Smartphone? A
    Response to Orin S. Kerr, 97 Tex. L. Rev. Online 63 (2019). Reasonable
    4Indeed, “Indiana has its own system of legal, including constitutional, protections” subject to
    our ultimate review. State v. Timbs, 
    84 N.E.3d 1179
    , 1184 (Ind. 2017), vacated and remanded.
    Although Seo mentioned Article 1, Section 14 in her briefing at the Court of Appeals (she filed
    nothing with this Court), she made no separate self-incrimination argument under the
    Indiana Constitution. See Ind. Const. art. 1, § 14 (“No person, in any criminal prosecution,
    shall be compelled to testify against himself.”). Because she failed to offer a “separate analysis
    based on the state constitution,” this “state constitutional claim is waived.” Dye v. State, 
    717 N.E.2d 5
    , 11 n.2 (Ind. 1999). If she had separately and independently analyzed Article 1,
    Section 14, we could have considered Seo’s case under our Indiana Constitution without
    needing to grapple with these heady Article III justiciability concerns.

    minds can disagree; indeed, many have. Our Court’s decision on the
    merits today is thus not unreasonable, though I would come out the other
    way for the reasons further explained by Professor Kerr.5
    Slaughter, J., joins in part.
    5 A few months before our nation’s bicentennial anniversary, the Supreme Court all but rang
    the death knell of longstanding precedent that barred the government from forcing a
    defendant “to give evidence that tends to criminate him,” Boyd v. United States, 
    116 U.S. 616
    ,
    638 (1886), holding that the Fifth Amendment is not violated merely because the State
    compels a defendant to turn over incriminating evidence, Fisher v. United States, 
    425 U.S. 391
    ,
    409 (1976). But the endurance of that view remains to be seen. Indeed, at least three sitting
    Justices of the U.S. Supreme Court have questioned this understanding. See Carpenter v. United
    States, 
    138 S. Ct. 2206
    , 2271 (2018) (Gorsuch, J., dissenting) (“[T]here is substantial evidence
    that the privilege against self-incrimination was also originally understood to protect a person
    from being forced to turn over potentially incriminating evidence.”); United States v. Hubbell,
    
    530 U.S. 27
    , 49 (2000) (Thomas, J., concurring) (“A substantial body of evidence suggests that
    the Fifth Amendment privilege protects against the compelled production not just of
    incriminating testimony, but of any incriminating evidence.”); Samuel A. Alito, Jr., Documents
    and the Privilege Against Self-Incrimination, 
    48 U. Pitt. L. Rev. 27
    , 78 (1986) (“The individuals
    who framed, adopted, and ratified the fifth amendment left no clear evidence that they ever
    considered the application of the privilege to subpoenas for documents.”). Even then-Justices
    Brennan and Stevens—no originalists!—agreed that the new framework unnecessarily and
    detrimentally departed from Boyd. See Fisher, 
    425 U.S. at 414
     (Brennan, J., concurring in the
    judgment) (Because it represented “a serious crippling of the protection secured by the
    privilege against compelled production of one’s private books and papers,” Fisher was “but
    another step in the denigration of privacy principles settled nearly 100 years ago” in Boyd.);
    Doe v. United States, 
    487 U.S. 201
    , 221 n.2 (1988) (Stevens, J., dissenting) (“The Fifth
    Amendment provides that no person ‘shall be compelled in any criminal case to be
    a witness against himself.’ A witness is one who ‘gives evidence in a cause.’ T. Cunningham,
    2 New and Complete Law Dictionary (2d ed. 1771).”). A return to Boyd would end the
    constitutional hair-splitting that results when applying old precedents to new technology in
    this digital age. But this Court, especially in a moot case, should not prognosticate Boyd’s
    resurrection. Cf. Timbs, 84 N.E.3d at 1183 (choosing “to await guidance from the Supreme
    Court and decline to find or assume incorporation until the Supreme Court decides the issue
    authoritatively”). The Supreme Court must, at some point, decide how to apply its modern
    Fifth Amendment jurisprudence to the compelled unlocking of a smartphone or, perhaps,
    return to Boyd. In the meantime, that uncertainty further counsels that we dismiss this appeal
    as moot.

    Slaughter, J., dissenting.
    I respectfully dissent. Although I agree with Justice Massa that this
    case is moot, I write separately because I disagree that a mootness
    exception justifies our reaching the merits of Seo’s constitutional claim. In
    my view, our prevailing mootness standard does not conform to our
    constitution’s mandate of separate governmental powers. In lieu of our
    prevailing standard, I would adopt the federal standard because,
    consistent with Article 3, Section 1 of our state constitution, it requires that
    courts decide only actual disputes. Applying this standard here, I would
    find Seo’s appeal moot and not reach the merits of her Fifth Amendment
    claim.
    A
    As Justice Massa recites correctly, appellate case law in Indiana holds
    that our courts may decide otherwise moot cases if the legal question is
    sufficiently important and will likely recur. The Court says that Seo’s
    appeal is such a case, thus justifying our reaching the merits even if her
    case were moot. Although case authority generally supports such a broad
    mootness exception, the cases are not uniform.
    Some cases appear to have applied the stricter federal exception, in
    which a court will not decide a moot issue unless it is capable of
    repetition, yet evading review. But courts that have applied the federal
    exception confuse the issue by also invoking our laxer state mootness
    standard. See, e.g., Horseman v. Keller, 
    841 N.E.2d 164
    , 170 (Ind. 2006)
    (invoking state standard first: “Where there is a matter of great public
    importance, however, and the possibility of repetition, Indiana courts may
    choose to adjudicate a claim.”; but concluding with federal standard:
    “Because the question before us is capable of repetition, yet evading
    review, we now address the constitutionality of [the disputed statute].”)
    (cleaned up); Gaither v. Indiana Dep’t of Correction, 
    971 N.E.2d 690
    , 693-94
    (Ind. Ct. App. 2012) (same).
    I would clarify any ambiguity in our appellate precedent and hold that
    any mootness doctrine consistent with our state constitution’s mandate of
    separate governmental powers requires an actual dispute.
    B
    Our constitution divides the powers of government among “three
    separate departments; the Legislative, the Executive including the
    Administrative, and the Judicial”. Ind. Const. art. 3, § 1. It also mandates
    that “except as in this Constitution expressly provided”, “no person,
    charged with official duties under one of these departments, shall exercise
    any of the functions of another”. Id. After discussing the powers and
    functions of the other departments, our constitution charges courts with
    exercising the “judicial power”. Id. art 7, § 1. This delegation of power to
    the judiciary has two aspects: courts may exercise only the judicial power;
    and only courts may exercise this power. Id.
    What, precisely, is the judicial power? It is the power to resolve actual
    disputes between adverse parties by issuing binding decrees that
    pronounce the parties’ rights and responsibilities and afford meaningful
    relief to the prevailing party. Although our constitution does not contain
    an express “case or controversy” requirement like Article III of the federal
    constitution, “our explicit separation of powers clause fulfills a similar
    function.” Pence v. State, 
    652 N.E.2d 486
    , 488 (Ind. 1995). Relevant here,
    that function limits courts to deciding justiciable controversies.
    Justiciability concerns the power and propriety of a court to hear a case
    and award relief. As I wrote in Horner v. Curry, standing is an essential
    aspect of justiciability because it ensures that a judicial decree redresses an
    actual injury attributable to the defendant’s wrong. 
    125 N.E.3d 584
    , 612,
    615 (Ind. 2019) (Slaughter, J., concurring in the judgment). Also essential
    are the related doctrines of ripeness and mootness. Standing asks who
    may bring suit. Ripeness and mootness ask when suit may be brought.
    With ripeness, the issue is whether the claim has sufficiently developed—
    matured—into an actual controversy so that courts are resolving real
    disputes, not anticipated cases based on hypothetical facts. With
    mootness, the issue is whether a once-mature claim has “over-ripened” to
    the point that a court’s judgment can no longer afford the claimant
    effective relief.
    These justiciability doctrines respect and implement separation of
    powers. They ensure that the judiciary retains its proper role within our
    Indiana Supreme Court | Case No. 18S-CR-595 | June 23, 2020           Page 2 of 4
    constitutional order and leaves the political branches undisturbed, absent
    a legal wrong. And even then, courts will not exercise their power unless a
    claimant has standing and the case is ripe. In other words, courts will hear
    a case only when a claim is sufficiently mature such that the claimant has
    sustained an actual injury; the claimant can obtain meaningful relief from
    a judgment against the defendant; and the claimant continues to have a
    personal stake in the outcome throughout the lawsuit. What follows from
    these doctrines is that the only mootness standard consistent with our
    constitution’s requirement of distributed governmental powers is one
    requiring an actual, ongoing controversy between adverse parties. The
    federal mootness standard fills that bill.
    To be justiciable, the federal standard requires that an otherwise moot
    case be capable of repetition, yet evading review. See Honig v. Doe, 
    484 U.S. 305
    , 318–20 (1988). In other words, it requires a case to present a
    question likely to recur between the same parties in circumstances that
    will likely skirt judicial review. See 
    id.
     Although the evade-review
    requirement is a prudential consideration, the capable-of-repetition
    requirement is constitutionally required, demanding a “demonstrated
    probability” that the same issue will arise between the same parties.
    Murphy v. Hunt, 
    455 U.S. 478
    , 482 (1982). “Where the conduct has ceased
    for the time being but there is a demonstrated probability that it will
    recur, a real-life controversy between parties with a personal stake in the
    outcome continues to exist[.]” Honig, 
    484 U.S. at 341
     (Scalia, J., dissenting)
    (emphasis in original). Thus, this so-called “exception” to the mootness
    doctrine is really no exception at all but a test for determining whether an
    actual dispute remains.
    In contrast, Indiana’s prevailing mootness doctrine rejects the narrow
    federal doctrine, see Matter of Lawrance, 
    579 N.E.2d 32
    , 37 (Ind. 1991), and
    recognizes an open-ended exception for moot cases involving “questions
    of great public interest”. 
    Id.

     we assess whether the issues are likely

     Thus, a court may decide an otherwise moot
    case if someone—anyone—may face the same issue in the future. But this
    lone requirement—an issue of great public importance likely to recur—

    does not make a case suitable for adjudication under our constitution. The
    case must have a demonstrated probability that it will recur between the
    same parties; otherwise, there is no actual dispute, and any adjudication
    exceeds the judicial power.
    Not only does our mootness doctrine lack any tie to our essential,
    though limited, constitutional role, but how we apply our justiciability
    principles has proved unpredictable in practice. Just last month, we held
    unanimously that the governor could not intervene in a pending
    disciplinary action involving the attorney general. Matter of Hill, 
    144 N.E.3d 200
     (Ind. 2020). The governor asked us to answer the timely,
    pressing question whether our thirty-day suspension of the attorney
    general’s law license created a vacancy in the office that triggered the
    governor’s legal duty to fill it. No one disputed that the governor’s motion
    raised an issue of “great public importance”. Yet we denied intervention
    —correctly, in my view—because, among other reasons, we do not issue
    advisory opinions and the governor had no legally cognizable interest in
    the underlying case. In other words, the proposed intervention lacked the
    criteria for justiciability, despite the importance of the issue raised.

    Even if I agreed that Seo has raised a “novel, important issue of great
    public importance that will surely recur”, that standard cannot be
    reconciled with the actual-injury requirement implicit in our constitution’s
    separation-of-powers command. Instead, I would adopt “capable of
    repetition, yet evading review” as our mootness standard. Applying it
    here, I would hold that Seo’s Fifth Amendment claim is moot and not
    reach the merits.
