    McKENNA, WILSON, AND EDDINS, JJ.; AND NAKAYAMA, J., DISSENTING,
    WITH WHOM RECKTENWALD, C.J., JOINS
    OPINION OF THE COURT BY McKENNA, J.
    I.   Introduction
    This appeal addresses Miranda rights arising out of police
    questioning of a person confined to a hospital bed.             Cyrina
    Hewitt (“Hewitt”) was charged in the District Court of the Third
    Circuit, Kona Division (“district court”) with operating a
    vehicle under the influence of an intoxicant (“OVUII”) and
    driving without a license (“DWOL”).     Hewitt moved to suppress
    evidence based on a failure to provide Miranda warnings.     The
    district court denied Hewitt’s motion, and Hewitt was convicted
    of both offenses after a bench trial.
    On appeal to the Intermediate Court of Appeals (“ICA”),
    Hewitt argued in part that she had been subjected to custodial
    interrogation without the requisite Miranda warnings.     In State
    v. Hewitt, 149 Hawai‘i 71, 
    481 P.3d 713
     (App. 2021), a published
    opinion, the ICA held that Miranda warnings were not required
    because Hewitt was not in custody at the time of questioning.
    The ICA ruled Hewitt was not entitled to Miranda warnings
    because (1) her inability to leave the scene of questioning was
    not the result of detention by law enforcement; (2) the officers
    did not have probable cause to arrest until Hewitt stated she
    had been driving a truck; and (3) the record did not reflect
    sustained and coercive questioning of Hewitt by the officers.
    Hewitt, 149 Hawaiʻi at 75, 481 P.3d at 717.    The ICA also held,
    however, that the district court erred by (1) overruling
    Hewitt’s Hawaiʻi Revised Statutes (“HRS”) § 621-26 (1993) trial
    objection by failing to conduct a voluntariness hearing; and (2)
    denying Hewitt’s motion to suppress her blood test result
    because a search warrant had not been obtained.     149 Hawaiʻi at
    76, 79, 481 P.3d at 718, 721.   On these grounds, the ICA vacated
    2
    Hewitt’s convictions and remanded.
    Hewitt sought certiorari review of the district court’s
    motion to suppress denial and the ICA’s Miranda analysis.
    Hewitt posited that, under the ICA’s rationale, anyone
    hospitalized but not under arrest need not be Mirandized because
    law enforcement did not prevent their ability to leave.
    We agree with Hewitt that the district court and ICA erred.
    First, we hold that Hewitt was in custody when probable cause
    developed.   State v. Sagapolutele-Silva, 151 Hawaiʻi 283, 
    511 P.3d 782
     (2022), overruled the bright-line rule articulated in
    State v. Ketchum, 97 Hawaiʻi 107, 
    34 P.3d 1006
     (2001), underlined
    below, which clearly held:
    [A] person is “in custody” for purposes of article I,
    section 10 of the Hawaiʻi Constitution if an objective
    assessment of the totality of the circumstances reflects
    either (1) that the person has become impliedly accused of
    committing a crime because the questions of the police have
    become sustained and coercive, such that they are no longer
    reasonably designed briefly to confirm or dispel their
    reasonable suspicion or (2) that the point of arrest has
    arrived because either (a) probable cause to arrest has
    developed or (b) the police have subjected the person to an
    unlawful “de facto” arrest without probable cause to do so.
    Ketchum, 97 Hawaiʻi at 126, 
    34 P.3d at 1025
     (emphases added).
    The Sagapolutele-Silva majority said it was clarifying that,
    despite this holding, the existence of probable cause is not
    conclusive and is only a factor to consider in determining
    whether someone is in custody under a “totality of
    circumstances” and therefore entitled to Miranda warnings.
    Sagapolutele-Silva, 151 Hawaiʻi at 287, 511 P.3d at 786.
    3
    We now expressly overrule Sagapolutele-Silva’s abrogation
    of Ketchum’s bright-line rule and hold that the Ketchum rule
    remains in effect:     Miranda warnings are required by article I,
    section 10 of the Constitution of the State of Hawaiʻi when
    probable cause to arrest has developed.    And in Hewitt’s case,
    contrary to the ICA’s conclusion, probable cause had developed
    before she was asked whether she had been driving.
    Second, we hold that, based on the totality of
    circumstances, Hewitt was in custody and was therefore entitled
    to Miranda warnings even before probable cause developed.     In
    addition to Ketchum’s bright-line rule, we have stated,
    “[W]hether the defendant was in custody or otherwise deprived of
    [their] freedom of action for Miranda purposes is to be
    determined from the totality of the circumstances, objectively
    appraised.”   State v. Patterson, 
    59 Haw. 357
    , 361, 
    581 P.2d 752
    ,
    755 (1978).   “These would include the place and time of the
    interrogation, the length of the interrogation, the nature of
    the questions asked, the conduct of the police, and all other
    relevant circumstances.”    
    Id.
    Police interrogation occurring in a medical treatment
    setting presents a special circumstance under the “totality of
    circumstances” test.    In United States v. Infante, 
    701 F.3d 386
    ,
    396 (1st Cir. 2012), the United States Court of Appeals for the
    First Circuit addressed whether the Fifth Amendment requires
    4
    Miranda warnings under these circumstances.     The court noted
    that when a person is unable to leave the place of an
    interrogation solely due to circumstances incident to medical
    treatment, it must be determined whether they were at liberty to
    terminate the interrogation and cause the officers to leave.
    
    701 F.3d at 396
    .
    We generally adopt the First Circuit’s approach for
    purposes of our constitution’s article I, section 10 right
    against self-incrimination.    We hold that if a person is unable
    to leave a place of interrogation due to circumstances incident
    to medical treatment, determining whether the person is “in
    custody” under a totality of circumstances requires an inquiry
    into whether the person was at liberty to terminate the
    interrogation and cause the officer to leave.
    As further discussed below, under the “totality of
    circumstances” of this case, Hewitt was in custody well before
    probable cause developed.     Hence, the district court and the ICA
    erred by holding that Miranda warnings were not required until
    Hewitt responded affirmatively to an officer’s question as to
    whether she had been driving a truck found damaged on a
    roadside.
    Hewitt’s convictions have already been set aside, however,
    based on developments discussed in Section IV.A below.     The
    nolle prosequi of both counts raises appellate jurisdiction and
    5
    mootness questions.     Hence, before addressing the merits of the
    issues on certiorari, we explain why appellate jurisdiction was
    retained.   We also clarify that mootness is a prudential
    consideration and not an issue of subject matter jurisdiction,
    and that the public interest exception to the mootness doctrine
    applies.
    Remand is no longer appropriate, however, whether for the
    grounds stated in the ICA opinion or in this opinion, and it is
    unnecessary to determine precisely when Hewitt should have been
    provided Miranda warnings.    Based on the procedural posture of
    this case, we reverse the ICA’s March 18, 2021 Judgment on
    Appeal and affirm the district court’s August 9, 2021 judgment
    of nolle prosequi of both counts.
    II.   Background
    1.   Factual background
    In 2014, Hawaiʻi County Police Department (“HCPD”) Officers
    Chandler Nacino (“Officer Nacino”) and Kaea Sugata (“Officer
    Sugata”) were called to Kona Community Hospital to interview
    Hewitt as a possible assault victim.     An unknown male had
    dropped Hewitt off at the hospital’s emergency room, and
    hospital staff contacted HCPD regarding Hewitt possibly being an
    assault victim.     Hewitt had large contusions on her face, eyes
    that were swollen shut, a laceration on her ear, and a broken
    breast plate.     Although awake, Hewitt appeared disoriented and
    6
    was “rambling incoherently.”        She did not know where she was or
    why she was in the hospital.
    Officers Nacino and Sugata first encountered Hewitt at
    around one o’clock in the morning.         They waited for the nurse
    administering Hewitt’s treatment to leave before starting an
    interview.     Hewitt gave the officers her name and birth date.
    Officer Nacino then served Hewitt with a “legal document” for an
    unrelated case and told her she needed to sign it.1            Both
    officers stood at Hewitt’s bedside during the interview while
    Officer Nacino did the majority of the talking.
    Officer Nacino asked Hewitt whether she had been assaulted
    and why her eyes were swollen.        Hewitt first responded she had
    pink-eye, but later said she had a stye.          To Officer Nacino,
    Hewitt’s injuries did not appear consistent with either
    explanation.
    At some point, Hawai‘i Fire Department (“HFD”) paramedics
    walked by and asked what was going on.          Officer Nacino said they
    were investigating a possible assault.          The paramedics said they
    had seen a truck’s taillights sticking out from roadside bushes.
    1     As the ICA noted, “[t]he record does not show what the document was, to
    what case it pertained, or why Officer Nacino had possession of the document
    at the time he was assigned to investigate an unidentified potential assault
    victim.” Hewitt, 149 Hawai‘i at 73 n.4, 481 P.3d at 715 n.4.
    7
    The police officers then left the room2 and contacted Sergeant
    Mekia Rose (“Sergeant Rose”) to check on the truck.
    Sergeant Rose located an unoccupied truck in some bushes on
    the shoulder of the road at the Queen Ka‘ahumanu Highway and
    Kuakini Highway intersection.        The truck had front-end damage,
    and both of its airbags had been deployed.          Sergeant Rose found
    Hewitt’s identification card in the truck and sent a photo of it
    via text message to Officer Nacino.         He also relayed the truck’s
    license plate number, a check of which revealed that the vehicle
    belonged to a “Cyrus Hewitt.”
    Officer Nacino returned to the room and asked Hewitt
    whether she had been in a traffic accident.           Hewitt answered
    yes, first stating that she was driving to a friend’s house and
    parked her vehicle there but later stating that she was going to
    a doctor’s appointment.       After this response, the officers
    stopped asking further questions and placed Hewitt under arrest
    for suspicion of OVUII.
    Before the arrest, the officers did not provide Hewitt any
    Miranda warnings.     They also did not tell Hewitt whether she was
    free to not respond to questions, leave, or terminate the
    conversation.
    After this, at around four o’clock in the morning, Hewitt
    2     The record does not reflect exactly when the officers left the room,
    but trial testimony suggests that the officers did leave at some point and
    “returned” or “recontacted” Hewitt after locating her vehicle.
    8
    was subjected to a blood draw without a search warrant having
    been requested or obtained.       Officer Nacino remained with Hewitt
    until the blood draw was completed.         He also ran a check on
    Hewitt’s driver’s license and learned that she had a suspended
    license.
    2.    District court proceedings
    On March 12, 2015, the State of Hawaiʻi (“the State”)
    charged Hewitt with OVUII and DWOL.         Before trial, Hewitt filed
    a motion to suppress statements alleging a violation of her
    constitutional rights under the federal and state constitutions.
    At the hearing just before the October 28, 2015 trial, the State
    argued that because Hewitt was not in custody, there was no
    constitutional violation.       The district court3 denied the motion
    to suppress and ultimately convicted Hewitt of OVUII in
    violation of HRS § 291E-61(a)(1) (2007)4 and DWOL in violation of
    HRS § 286-102(b) (Supp. 2013).5
    3     The Honorable Margaret K. Masunaga presided.
    4     §291E-61 Operating a vehicle under the influence of an intoxicant.
    (a) A person commits the offense of operating a vehicle under the
    influence of an intoxicant if the person operates or assumes
    actual physical control of a vehicle:
    (1) While under the influence of alcohol in an amount sufficient
    to impair the person’s normal mental faculties or ability to care
    for the person and guard against casualty[.]
    HRS § 291E-61(a)(1) (2007).
    5     §286-102 Licensing.
    . . . .
    (b) A person operating the following category or combination of
    categories of motor vehicles shall be examined as provided in
    section 286-108 and duly licensed by the examiner of drivers:
    9
    3.    ICA proceedings
    Hewitt filed a notice of appeal on June 14, 2016.               On
    appeal, Hewitt argued, inter alia, that the district court erred
    in denying her motion to suppress because she had been subjected
    to custodial interrogation without any Miranda warnings before
    her statement.     In a published opinion, the ICA concluded, in
    relevant part, that Hewitt was not in custody at the time of
    questioning because (1) Hewitt’s inability to leave was not the
    result of detention by law enforcement; (2) the officers did not
    have probable cause to arrest Hewitt until she stated she had
    been driving the truck; and (3) the record did not reflect any
    sustained and coercive questioning of Hewitt by the officers.
    Hewitt, 149 Hawaiʻi at 75, 481 P.3d at 717.
    The ICA also held, however, that the district court erred
    by overruling Hewitt’s HRS § 621-26 (1993)6 trial objection and
    (1) Mopeds;
    (2) Motorcycles and motor scooters;
    (3) Passenger cars of any gross vehicle weight rating, buses
    designed to transport fifteen or fewer occupants, and
    trucks and vans having a gross vehicle weight rating of
    eighteen thousand pounds or less; and
    (4) All of the motor vehicles in category (3) and any vehicle
    that is not a commercial motor vehicle.
    A school bus or van operator shall be properly licensed to
    operate the category of vehicles that the operator operates as a
    school bus or van and shall comply with the standards of the
    department of transportation as provided by rules adopted
    pursuant to section 286-181.
    HRS § 286-102(b) (Supp. 2013).
    6     §621-26 Confessions when admissible. No confession shall be
    received in evidence unless it is first made to appear to the
    10
    by failing to conduct a hearing on the voluntariness of her
    statement;7 and (2) the district court erred by denying Hewitt’s
    motion to suppress her blood test result.8          149 Hawaiʻi at 76,
    judge before whom the case is being tried that the confession was
    in fact voluntarily made.
    HRS § 621-26 (1993).
    7     The ICA held the district court erred by failing to conduct a hearing
    on the voluntariness of Hewitt’s statement that she was driving the vehicle
    and had parked it in the bushes. Hewitt, 149 Hawaiʻi at 76, 481 P.3d at 718.
    The ICA ruled that, rather than overruling Hewitt’s HRS § 621-26 objection,
    the district court should have conducted an evidentiary hearing to determine
    whether Hewitt’s statement was voluntarily made, in light of the evidence
    that Hewitt had sustained significant head trauma, did not know where she
    was, and was incoherent. Id.
    8     The ICA noted that although the State argued that Hewitt’s motion to
    suppress evidence of the alcohol content of her blood was not timely filed
    under Hawaiʻi Rules of Penal Procedure (“HRPP”) Rule 12(c) (2007), the
    district court had the discretion to proceed to rule on the merits, citing
    State v. Przeradski, 
    5 Haw.App. 29
    , 32, 
    677 P.2d 471
    , 474-75 (1984), and
    therefore, the denial of the motion on its merits was properly before the
    ICA. Hewitt, 149 Hawaiʻi at 76, 481 P.3d at 718. The ICA appropriately noted
    that although the district court relied upon Schmerber v. California, 
    384 U.S. 757
     (1966) in denying Hewitt’s motion to suppress, Missouri v. McNeely,
    
    569 U.S. 141
     (2013), which was decided after State v. Entrekin, 98 Hawaiʻi
    221, 
    47 P.3d 336
     (2002) (discussing Schmerber), held “that in drunk-driving
    investigations, the natural dissipation of alcohol in the bloodstream does
    not constitute an exigency in every case sufficient to justify conducting a
    blood test without a warrant.” 149 Hawaiʻi at 77, 481 P.3d at 719. The ICA
    noted that it cited McNeely in State v. Niceloti-Velazquez, 139 Hawaiʻi 203,
    
    386 P.3d 487
     (App. 2016), in which it held the trial court erred by holding
    exigent circumstances existed to justify the warrantless extraction of the
    defendant’s blood sample, because the trial court only cited the risk of
    blood alcohol dissipation to support its finding of exigency and the State
    failed to adequately develop the record to demonstrate that the police
    officers were justified to act without a warrant. 149 Hawaiʻi at 78, 481 P.3d
    at 720.
    The ICA opined that the facts of this case illustrate why more than
    just “the risk of blood dissipation” should be required to justify a
    warrantless blood draw. Id. The ICA stated that Officer Nacino did not
    testify that he detected an odor similar to that of an alcoholic beverage on
    Hewitt’s breath or body; there was no evidence that empty or open containers
    of liquor, or a bar or restaurant tab or other receipt evidencing the recent
    consumption of alcohol, were found in Hewitt’s truck or with her
    identification card; Hewitt’s apparent disorientation could have been
    explained by a concussion, as evidenced by her significant head trauma;
    although she knew who she was, she did not know where she was; there was no
    evidence that Officer Nacino attempted to determine if Hewitt was oriented to
    time (as one would to attempt to diagnose or rule out a concussion); and
    11
    79, 481 P.3d at 718, 721.       The ICA remanded the case for a new
    trial.
    4.   Certiorari
    Hewitt’s certiorari application presents a single question:
    whether the ICA gravely erred in holding that the district court
    did not err in denying Hewitt’s motion to suppress because
    Hewitt was not in custody.           We accepted certiorari.
    III.    Standard of Review
    “An appellate court reviews a ruling on a motion to
    suppress de novo to determine whether the ruling was ‘right’ or
    ‘wrong.’”    State v. Weldon, 144 Hawaiʻi 522, 530, 
    445 P.3d 103
    ,
    111 (2019) (quoting State v. Tominiko, 126 Hawaiʻi 68, 75, 
    266 P.3d 1122
    , 1129 (2011)).
    IV.    Discussion
    A.   Preliminary issues
    Before addressing the issue on certiorari, we address
    unusual developments after our acceptance of certiorari, which,
    Hewitt’s disorientation could also have been the result of prescription
    medication administered to her in the hospital emergency room. 149 Hawaiʻi at
    79, 481 P.3d at 721. The ICA concluded that under the totality of these
    circumstances, it would not have been unreasonable for a judge to require
    more information before issuing a warrant for a blood draw; there was no
    evidence that Officer Nacino, Officer Sugata, Sergeant Rose, or any other
    police officer attempted to contact a judge to obtain a warrant before
    requesting the blood draw. Id. Thus, the ICA held the State failed to
    adequately develop the record to demonstrate the existence of exigent
    circumstances that would have justified Officer Nacino requesting a
    warrantless blood draw, and therefore, the district court erred in denying
    Hewitt’s motion to suppress the blood test results. Id.
    12
    at first blush, might appear to raise questions of appellate
    jurisdiction and mootness.
    1.    Background after acceptance of certiorari
    As noted, the ICA’s published opinion ruled in the State’s
    favor regarding the motion to suppress denial, and this was the
    only question raised by Hewitt on certiorari.           Immediately after
    we entered our order accepting certiorari, however, the State
    contacted Hewitt’s counsel and offered to dismiss Hewitt’s case
    with prejudice if Hewitt dismissed the instant certiorari
    proceeding.    Hewitt therefore filed a motion requesting a
    temporary remand of this appeal to the district court.9             Our
    order regarding this motion provided:
    IT IS HEREBY ORDERED that the motion is granted as
    follows. This case shall be temporarily remanded to the
    District Court of the Third Circuit for no more than 30
    days. No later than 30 days after this order, the clerk of
    the district court shall supplement the record on appeal
    with all documents entered on temporary remand, and the
    case shall then resume in the Supreme Court for such
    further proceedings as may be appropriate.
    On remand, the State filed a motion for nolle prosequi10
    with prejudice as to the complaint against Hewitt.            The State
    indicated it filed the motion “due to the ICA opinion on appeal
    following bench trial and in the interest of justice.”             The
    9     Hawaiʻi Rules of Appellate Procedure (“HRAP”) Rule 42 requires appellate
    court approval of any dismissal.
    10    The expression nolle prosequi, or more fully, dicit nolle prosequi,
    means that the government will not prosecute. The King v. Robertson, 
    6 Haw. 718
    , 
    1889 WL 1054
     (Haw. Kingdom 1889).
    13
    district court11 granted the motion and filed a judgment
    indicating a disposition of “nolle prosequi” for both counts.
    The district court’s supplemental record was filed pursuant to
    our order of temporary remand, and we scheduled oral argument.
    Hewitt then filed a motion to set aside the oral argument
    setting or to clarify the status of the case due to the nolle
    prosequi on remand.12     We entered an order denying the motion to
    set aside the oral argument, and we now explain why.
    2.    This court retained appellate jurisdiction pursuant to
    the order of temporary remand
    Based on our order of temporary remand, the district
    court’s judgment of nolle prosequi did not terminate this
    certiorari proceeding.      Pursuant to HRS § 602-5(a)(6) (Supp.
    2004), this court has jurisdiction:
    [t]o make . . . such . . . orders   . . . and do such other
    acts and take such other steps as   may be necessary to carry
    into full effect the powers which   are or shall be given to
    it by law or for the promotion of   justice in matters
    pending before it.
    Our order specifically provided that, after remand, the
    case would resume in this court “for such further proceedings as
    may be appropriate.”      Thus, this court retained appellate
    jurisdiction despite the nolle prosequi.
    11   The Honorable Robert J. Crudele presided.
    12    The State’s motion requested a dismissal of both counts “with
    prejudice.” The judgment did not include language indicating the dismissal
    was with prejudice. This lack of clarity is immaterial to the issues we
    discuss.
    14
    3.    The “public interest” exception to the mootness
    doctrine is applicable
    Although we retained appellate jurisdiction, the charges
    against Hewitt were mooted based on the nolle prosequi of both
    counts.    We therefore address mootness.
    We first clarify that mootness is a prudential
    consideration and not an issue of subject matter jurisdiction,
    as we have stated, even recently.13        Tax Foundation v. State, 144
    Hawaiʻi 175, 
    439 P.3d 127
     (2019), addressed standing, a
    “prudential concern of judicial governance” like “mootness”:
    As explained by Justice Nakamura in Trustees of the Office
    of Hawaiian Affairs v. Yamasaki, 
    69 Haw. 154
    , 
    737 P.2d 446
    (1987):
    Unlike the federal judiciary, the courts of Hawaiʻi
    are not subject to a cases or controversies
    limitation like that imposed by Article III, § 2 of
    the United States Constitution. But like the federal
    government, ours is one in which the sovereign power
    is divided and allocated among three co-equal
    branches. Thus, we have taken the teachings of the
    Supreme Court to heart and adhered to the doctrine
    that the use of judicial power to resolve public
    disputes in a system of government where there is a
    separation of powers should be limited to those
    questions capable of judicial resolution and
    presented in an adversary context. And, we have
    admonished our judges that even in the absence of
    constitutional restrictions, they must still
    carefully weigh the wisdom, efficacy, and timeliness
    of an exercise of their power before acting,
    especially where there may be an intrusion into areas
    committed to other branches of government.
    13    See, e.g., Skahan v. Stutts Constr. Co., Inc., 148 Hawaiʻi 460, 468 n.7,
    
    478 P.3d 285

    15
    Our guideposts for the application of the rules
    of judicial self-governance founded in concern about
    the proper — and properly limited — role of courts in
    a democratic society reflect the precepts enunciated
    by the Supreme Court. When confronted with an
    abstract or hypothetical question, we have addressed
    the problem in terms of a prohibition against
    rendering advisory opinions; when asked to decide
    whether a litigant is asserting legally recognized
    interests, personal and peculiar to him, we have
    spoken of standing; when a later decision appeared
    more appropriate, we have resolved the justiciability
    question in terms of ripeness; and when the continued
    vitality of the suit was questionable, we have
    invoked the mootness bar.
    Thus, Yamasaki recognizes that standing is a prudential
    concern in Hawaiʻi state courts, which are not subject to
    the case and controversy subject matter jurisdiction
    limitation of federal courts. Yamasaki also noted that
    standing is a prudential concern “founded in concern about
    the proper – and properly limited – role of courts in a
    democratic society.”

    )
    (cleaned up).
    As noted in Yamasaki, “mootness,” like “standing,” is a
    prudential concern not subject to the “case and controversy”
    subject matter jurisdiction limitation of federal courts.               
    69 Haw. at 170-72
    , 
    737 P.2d at 455-56
    .        In Tax Foundation, we noted
    that courts of other states recognize that standing is a
    prudential concern regarding justiciability and is not an issue
    of subject matter jurisdiction.       144 Hawaiʻi at 191, 
    439 P.3d at 143
    .   Most other state courts also recognize that mootness is a
    prudential concern regarding justiciability, not an issue of
    subject matter jurisdiction.       See, e.g., Matter of Big Foot
    Dumpsters & Containers, LLC, 
    507 P.3d 169
    , 173 (Mont. 2022)
    16
    (noting mootness is a concept of justiciability); Nesbitt v.
    Frakes, 
    911 N.W.2d 598
    , 603 (Neb. 2018) (holding mootness is a
    justiciability doctrine that does not prevent appellate
    jurisdiction); Couey v. Atkins, 
    355 P.3d 866
    , 901 (Or. 2015)
    (holding that the Oregon state constitution does not require
    dismissal of a case based on the justiciability doctrine of
    mootness); DeMarco v. Travelers Ins. Co., 
    102 A.3d 616
    , 622
    (R.I. 2014) (holding mootness is a distinct concept, separate
    and apart from subject-matter jurisdiction); Wylie v. State of
    Idaho Transp. Bd., 
    253 P.3d 700
    , 705 (Idaho 2011) (noting
    mootness is a subcategory of justiciability);   McIntyre v.
    Traughber, 
    884 S.W.2d 134
    , 137 (Tenn. Ct. App. 1994) (noting
    mootness is a doctrine of justiciability).   Thus, mootness is an
    issue of justiciability, not an issue of subject matter
    jurisdiction.
    Under Hawaiʻi law, a well-recognized exception to the
    mootness doctrine is for matters “affecting the public
    interest.”   See State v. Kiese, 126 Hawaiʻi 494, 509, 
    273 P.3d 1180
    , 1195 (2012).   This exception applies here.
    Only after we accepted Hewitt’s certiorari application on
    an issue for which the ICA had ruled in the State’s favor in a
    published opinion did the State offer to dismiss Hewitt’s case
    with prejudice; the State made the offer conditioned upon
    Hewitt’s dismissal of this appeal.   On temporary remand, the
    17
    State indicated it filed the motion to nolle prosequi the case
    with prejudice for two reasons: “the ICA opinion on appeal
    following bench trial”; and “in the interest of justice.”     The
    State may have realized that the district court had erred with
    respect to voluntariness, especially due to the testimony
    regarding Hewitt’s condition during questioning.     The State may
    also have realized that, as ruled by the ICA, a search warrant
    should have been obtained before the blood draw.     But this court
    had just accepted certiorari on the custody issue, an issue on
    which the State had obtained a favorable opinion from the ICA.
    If this certiorari was dismissed pursuant to the State’s offer,
    the ICA’s published opinion would remain as precedent despite
    the errors of law discussed in Section IV.B below.
    Under these circumstances, the “public interest” exception
    to the mootness doctrine applies.   Although factually and
    procedurally distinguishable, concerns expressed in Ocean Resort
    Villas Vacation Owners Ass’n v. County of Maui, 147 Hawai‘i 544,
    
    465 P.3d 991
     (2020), which addressed “stipulated reversals” of
    trial court judgments are instructive.   In that case, we cited
    to a law review article highlighting the “‘tangible but
    frequently undetectable social costs’ of allowing [appellate]
    courts to consider vacaturs based solely on the parties’
    settlement during the pendency of an appeal”:
    18
    The costs . . . include the . . . loss of precedential
    value for judicial decisions, and a diminished respect for
    the judicial process. . . . A procedure which allows
    parties to obtain vacatur as a matter of right . . . will
    encourage parties to delay settlement until after trial
    because the effects of an adverse judgment can be avoided
    at little or no cost by postjudgment settlement. The
    procedure . . . will place the defense of the integrity of
    judicial decisions in the hands of litigants who are not in
    a position to safeguard the public values inherent therein.
    147 Hawaiʻi at 560, 465 P.3d at 1007 (quoting Jill E. Fisch,
    Rewriting History: The Propriety of Eradicating Prior Decisional
    Law Through Settlement and Vacatur, 
    76 Cornell L. Rev. 589
    , 641-
    42 (1991)) (cleaned up).
    Allowing the State to nolle prosequi charges after a
    favorable ICA opinion in exchange for dismissal of an appeal
    would likewise (1) result in the loss of precedential value of
    judicial decisions from this court; (2) cause a diminished
    respect for the judicial process; (3) allow parties to obtain
    dismissal as a matter of right, which could encourage the State
    to delay offering dismissal until after certiorari is accepted
    to see if a possible adverse opinion can be avoided; and (4)
    place the defense of the integrity of judicial decisions in the
    hands of litigants who are not in a position to safeguard the
    public values inherent therein.14         However well-intentioned the
    14    With respect to (4), an individual defendant has no real incentive to
    continue with a certiorari proceeding after receiving an offer to nolle
    prosequi with prejudice. The nolle prosequi would be a sure thing, and a
    defendant does not know how this court will rule on certiorari. We have no
    concern with the actions taken by Hewitt’s counsel after receipt of the
    State’s offer to nolle prosequi with prejudice in exchange for a dismissal of
    the appeal. Counsel’s obligation was to represent Hewitt’s interests, and
    counsel took appropriate actions to do so.
    19
    State’s offer might have been, dismissal would have precluded
    this court from reviewing an issue on which the State had
    obtained a favorable published opinion from the ICA.            For the
    reasons discussed in Section III.B below, the public interest
    exception to the mootness doctrine applies here despite the
    dismissal of the charges against Hewitt.
    B.   Custody
    We therefore address the merits of the issue raised on
    certiorari:      whether the ICA erred in determining that Hewitt
    was not in custody at the time she made her statements and that
    Miranda warnings were therefore not required.
    1.     General Miranda principles
    The Fifth Amendment to the U.S. Constitution provides, in
    relevant part, that no person “shall be compelled in any
    criminal case to be a witness against himself[.]”            U.S. Const.
    amend. V.      Article I, section 10 of the Hawaiʻi Constitution
    similarly guarantees a privilege against self-incrimination to
    our state’s citizens.      See State v. Ah Loo, 94 Hawaiʻi 207, 210,
    
    10 P.3d 728
    , 731 (2000).       Miranda warnings help safeguard this
    right:
    The Miranda rule is, at core, a constitutionally
    prescribed rule of evidence that requires the prosecution
    to lay a sufficient foundation—i.e., that the requisite
    warnings were administered and validly waived before the
    accused gave the statement sought to be adduced at trial—
    before it may adduce evidence of a defendant’s custodial
    statements that stem from interrogation during [their]
    criminal trial.
    20
    The prosecution’s burden of establishing that the
    requisite warnings were given, however, is not triggered
    unless the totality of the circumstances reflect that the
    statement it seeks to adduce at trial was obtained as a
    result of “custodial interrogation,” which, as the United
    States Supreme Court defined it in Miranda, consists of
    “questioning initiated by law enforcement officers after a
    person has been taken into custody or otherwise deprived of
    [their] freedom of action in any significant way.” In
    other words, the defendant, objecting to the admissibility
    of [their] statement and, thus, seeking to suppress it,
    must establish that [their] statement was the result of (1)
    “interrogation” that occurred while [they were] (2) “in
    custody.”
    State v. Wallace, 105 Hawaiʻi 131, 137, 
    94 P.3d 1275
    , 1281 (2004)
    (cleaned up).   Thus, a statement made by a defendant under
    custodial interrogation without a Miranda warning must be
    suppressed as unconstitutionally elicited.
    2.   Hewitt was in custody when probable cause developed
    and Sagapolutele-Silva is overruled to the extent it
    said the existence of probable cause is not
    dispositive on the issue of whether a person is in
    custody for purposes of Miranda warnings required by
    the Hawaiʻi constitution
    In Ketchum, we articulated that a person is in custody for
    purposes of Miranda warnings as required by the Hawaiʻi
    Constitution:
    [I]f an objective assessment of the totality of the
    circumstances reflects either (1) that the person has
    become impliedly accused of committing a crime because the
    questions of the police have become sustained and coercive,
    such that they are no longer reasonably designed briefly to
    confirm or dispel their reasonable suspicion or (2) that
    the point of arrest has arrived because either (a) probable
    cause to arrest has developed or (b) the police have
    subjected the person to an unlawful “de facto” arrest
    without probable cause to do so.
    Ketchum, 97 Hawai‘i at 126, 
    34 P.3d at 1025
    .
    21
    The majority in Sagapolutele-Silva said it was clarifying
    that despite this holding, the existence of probable cause is
    but one factor in the totality of circumstances test.    151
    Hawaiʻi at 291, 511 P.3d at 390.
    Ketchum stated a clear, easily applied, bright-line rule:
    when probable cause to arrest exists upon an initial stop or
    detention, the Hawaiʻi constitution requires that Miranda rights
    be given before “interrogation” occurs.    Ketchum, 97 Hawaiʻi at
    126, 
    34 P.3d 1006
     at 1025.    Even before Ketchum, we had held
    that “if the detained person’s responses to a police officer’s
    questions provide the officer with probable cause to arrest . .
    . the officer is—-at that time—-required to inform the detained
    person of his or her constitutional rights against self-
    incrimination and to counsel, as mandated by Miranda and its
    progeny.”   State v. Loo, 94 Hawaiʻi 207, 212, 
    10 P.3d 728
    , 733
    (2000) (citing State v. Melemai, 
    64 Haw. 479
    , 481-82, 
    643 P.2d 541
    , 543-44 (1982)).   Ketchum followed within a year, setting
    out the rule quoted above pursuant to article I, section 10 of
    the Hawaiʻi constitution.    97 Hawaiʻi at 126, 
    34 P.3d 1006
     at
    1025.
    Bright-line rules foster uniformity and predictability.
    See Antonin Scalia, The Rule of Law as a Law of Rules, 
    56 U. Chi. L. Rev. 1175
    , 1179 (1989).    The most significant role of
    judges may be to protect the individual criminal defendant
    22
    against the occasional excesses of popular will, and to preserve
    the checks and balances within our constitutional system that
    are designed to inhibit that popular will.         
    Id.,
     56 U. Chi. L.
    Rev. at 1180.    In terms of constitutional rules of criminal
    procedure, in order to preserve checks and balances, bright-line
    rules are therefore preferable.15
    15   As Justice Scalia stated:
    I had always thought that the common-law [“totality
    of circumstances”] approach had at least one thing to be
    said for it: it was the course of judicial restraint,
    “making” as little law as possible in order to decide the
    case at hand. I have come to doubt whether that is true.
    For when, in writing for the majority of the Court, I adopt
    a general rule, and say, “This is the basis of our
    decision,” I not only constrain lower courts, I constrain
    myself as well. If the next case should have such
    different facts that my political or policy preferences
    regarding the outcome are quite the opposite, I will be
    unable to indulge those preferences; I have committed
    myself to the governing principle. In the real world of
    appellate judging, it displays more judicial restraint to
    adopt such a course than to announce that, “on balance,” we
    think the law was violated here—leaving ourselves free to
    say in the next case that, “on balance,” it was not. It is
    a commonplace that the one effective check upon arbitrary
    judges is criticism by the bar and the academy. But it is
    no more possible to demonstrate the inconsistency of two
    opinions based upon a “totality of the circumstances” test
    than it is to demonstrate the inconsistency of two jury
    verdicts. Only by announcing rules do we hedge ourselves
    in.
    While announcing a firm rule of decision can thus
    inhibit courts, strangely enough it can embolden them as
    well. Judges are sometimes called upon to be courageous,
    because they must sometimes stand up to what is generally
    supreme in a democracy: the popular will. Their most
    significant roles, in our system, are to protect the
    individual criminal defendant against the occasional
    excesses of that popular will, and to preserve the checks
    and balances within our constitutional system that are
    precisely designed to inhibit swift and complete
    accomplishment of that popular will. Those are tasks
    which, properly performed, may earn widespread respect and
    admiration in the long run, but—almost by definition—never
    in the particular case. The chances that frail men and
    women will stand up to their unpleasant duty are greatly
    23
    Determining whether a defendant is in custody under a
    totality of circumstances requires consideration of many factors
    other than the existence of probable cause.          In Sagapolutele-
    Silva, however, the majority eliminated the bright-line
    “probable cause” test for custody and required analyzing
    “custody” based on multiple factors.        151 Hawaiʻi at 292, 511
    P.3d at 791.
    Also, until Sagapolutele-Silva, this court had
    “consistently provided criminal defendants with greater
    protection under Hawaiʻi’s version of the privilege against self-
    incrimination (article I, section 10 of the Hawaiʻi Constitution)
    than is otherwise ensured by the federal courts under Miranda
    and its progeny.”     State v. Valera, 
    74 Haw. 424
    , 434, 
    848 P.2d 376
    , 380 (1993).     The majority in Sagapolutele-Silva actually
    attempted to retrench on Hawaiʻi constitutional rights.           The
    Ketchum bright-line rule enhances protection of our citizens’
    constitutional rights and equal treatment of people under the
    law.
    increased if they can stand behind the solid shield of a
    firm, clear principle enunciated in earlier cases. It is
    very difficult to say that a particular convicted felon who
    is the object of widespread hatred must go free because, on
    balance, we think that excluding the defense attorney from
    the line-up process in this case may have prevented a fair
    trial. It is easier to say that our cases plainly hold
    that, absent exigent circumstances, such exclusion is a per
    se denial of due process.
    56 U. Chi. L. Rev. at 1179-80.
    24
    We therefore expressly overrule Sagapolutele-Silva’s
    abrogation of Ketchum’s bright-line rule and, based on the
    above, hold that the Ketchum rule remains in effect:    Miranda
    warnings are required by article I, section 10 of the
    Constitution of the State of Hawaiʻi when probable cause to
    arrest has developed.   Ketchum, 97 Hawaiʻi at 126, 
    34 P.3d at 1025
    .
    Hence, at the point probable cause to arrest Hewitt had
    developed, which was at least by the time officers learned the
    truck owned by “Cyrus Hewitt” crashed on the roadside contained
    Hewitt’s identification card, she was entitled to Miranda
    warnings before questioning recommenced.   For the reasons
    discussed below, however, Hewitt was in custody under a totality
    of circumstances and entitled to Miranda warnings even before
    that point in time.
    3.   Based on the totality of circumstances, Hewitt was
    already in custody even before probable cause
    developed
    The ICA ruled that Hewitt was not in custody at the time
    she made her statement about having driven the truck because (1)
    her inability to leave was not the result of detention by law
    enforcement; (2) the officers did not have probable cause to
    arrest Hewitt until she stated she had been driving the truck;
    and (3) the record does not reflect any sustained and coercive
    25
    questioning of Hewitt by the officers.   Hewitt, 149 Hawaiʻi at
    75, 481 P.3d at 717.
    When a bright-line rule regarding “custody” (such as the
    existence of probable cause) has yet to be triggered, “[w]hether
    the defendant was in custody or otherwise deprived of [their]
    freedom of action for Miranda purposes is to be determined from
    the totality of the circumstances, objectively appraised.”
    Patterson, 
    59 Haw. at 361
    , 
    581 P.2d at 755
    .    “These
    [circumstances] would include the place and time of the
    interrogation, the length of the interrogation, the nature of
    the questions asked, the conduct of the police, and all other
    relevant circumstances.”   
    Id.
    Thus, the circumstance of a person being questioned while
    in a hospital bed or receiving medical treatment is relevant to
    the “totality of circumstances” analysis.     Other courts have
    specifically addressed questioning by law enforcement of a
    person in a hospital bed or receiving medical treatment.     The
    First Circuit has stated that “[w]hen an individual is unable to
    ‘leave’ the place of the interrogation solely due to
    circumstances incident to medical treatment, the question is
    said to be slightly different:   whether [they were] at liberty
    to terminate the interrogation and ‘cause the [officers] to
    26
    leave.’”   Infante, 
    701 F.3d at 396
    , modified on other grounds by
    Hill v. Walsh, 
    884 F.3d 16
     (1st Cir. 2018).16
    16    Other courts have articulated different tests regarding whether custody
    is established when a person is unable to leave the hospital due to their
    medical condition. See State v. Pontbriand, 
    878 A.2d 227
    , 231-32 (Vt. 2005).
    The United States Court of Appeals for the Fourth Circuit adopted a
    “reasonably free to terminate questioning and leave” test:
    The question of custody typically turns on whether “a
    reasonable person [would] have felt [they were] not at
    liberty to terminate the interrogation and leave.”
    Thompson v. Keohane, 
    516 U.S. 99
    , 112, 
    116 S.Ct. 457
    , 
    133 L.Ed.2d 383
     (1995). In some circumstances, however, the
    defendant may be prevented from pretermitting the
    interrogation because of factors independent of police
    restraint. For example, in Florida v. Bostick, the
    defendant's “freedom of movement was restricted by a factor
    independent of police conduct—i.e., by his being a
    passenger on a bus”—which rendered the standard “free to
    leave” analysis inapplicable. 
    501 U.S. 429
    , 436, 
    111 S.Ct. 2382
    , 
    115 L.Ed.2d 389
     (1991) (emphasis omitted). In such
    circumstances, “the appropriate inquiry is whether a
    reasonable person would feel free to decline officers’
    requests or otherwise terminate the encounter.” 
    Id. at 436
    , 
    111 S.Ct. 2382
    .
    This court came to a similar conclusion in United
    States v. Conley, 
    779 F.2d 970
     (4th Cir. 1985), a case
    decided before Bostick. . . .
    . . . .
    Analysis of whether Jamison was in custody when he
    made the statements describing the shooting depends on
    “whether a reasonable person would [have] fe[lt] free to
    decline the officers’ requests or otherwise terminate the
    encounter,” Bostick, 
    501 U.S. at 436
    , 
    111 S.Ct. 2382
    . In
    dissecting the perceptions of such a reasonable person,
    however, we must be careful to separate the restrictions on
    his freedom arising from police interrogation and those
    incident to his background circumstances. That is, to the
    extent Jamison felt constrained by his injuries, the
    medical exigencies they created (e.g., the donning of a
    hospital gown and the insertion of an I.V. line), or the
    routine police investigation they initiated, such
    limitations on his freedom should not factor into our
    reasonable-person analysis. It is this careful
    differentiation between police-imposed restraint and
    circumstantial restraint that leads us to conclude that
    Jamison was not in custody when he described the shooting
    during his hospital interview. The district court properly
    invoked the same lodestar, but proceeded to classify the
    significant limitations on Jamison’s freedom as police-
    imposed when they were actually routine treatment for a
    person in Jamison’s position.
    27
    We generally adopt the First Circuit’s approach for
    purposes of the article I, section 10 right against self-
    incrimination.     We hold that, under the Hawaiʻi Constitution, if
    a person is unable to leave a place of interrogation due to
    circumstances incident to medical treatment, determining whether
    the person is “in custody” under a totality of circumstances
    requires an inquiry into whether the person was at liberty to
    terminate the interrogation and cause the officer(s) to leave.
    Applying that inquiry here, at the time of the questioning,
    Hewitt lay in a hospital bed with contusions on her face, eyes
    swollen shut, a laceration on her ear, and a broken breast
    plate.   Early in the officers’ encounter with Hewitt, Officer
    Nacino served her with a “legal document” and told her that she
    needed to sign the document.       The officers proceeded to question
    Hewitt about her injuries.       She did not know where she was or
    why she was there.
    Both officers stood at her bedside throughout the
    interview, which started around one o’clock in the morning and
    continued intermittently until about three hours later.
    United States v. Jamison, 
    509 F.3d 623
    , 629 (4th Cir. 2007) (alterations in
    original).
    We disagree with the Fourth Circuit that limitations on a person’s
    freedom due to background medical treatment circumstances should not factor
    into the custody analysis. Such circumstances are relevant to the
    determination of whether a person is at liberty to terminate the
    interrogation and cause the officers to leave.
    28
    Hewitt’s responses were largely incoherent.    The officers had to
    continually wake her up throughout the interview because she had
    been heavily sedated.    When Hewitt finally left the hospital,
    she could not do so on her own, and her friend had to assist her
    movements.   Hewitt was not at liberty to terminate the
    interrogation and cause the officers to leave.
    Applying other factors relevant to the “totality of
    circumstances” analysis, Hewitt had also become the focus of an
    OVUII investigation before Officer Nacino asked whether she had
    been driving.   See Patterson, 
    59 Haw. at 361
    , 
    581 P.2d at 755
    (holding that the focus of the investigation upon the defendant
    is an important factor in the determination of whether the
    defendant was subjected to custodial interrogation).    In this
    regard, at the start of the officers’ shift and before they even
    went to the hospital, HCPD received a report that somebody heard
    a traffic collision.    The officers suspected Hewitt was under
    the influence of alcohol or another intoxicant.    While Officer
    Nacino questioned Hewitt, HFD paramedics informed the officers
    of a truck apparently involved in a traffic collision and
    suggested that Hewitt was somehow connected.    When the officers
    called Sergeant Rose to confirm the truck’s whereabouts, they
    already doubted that Hewitt’s injuries were from an assault as
    they told Sergeant Rose that “a person was at the hospital for
    injuries, which they didn’t know if it was from an assault or
    29
    from a traffic accident” and “received information that there
    was a possible crash.”17
    Hence, under the totality of circumstances, Hewitt was in
    custody and entitled to Miranda warnings well before the
    officers asked her whether she had been driving the truck.             The
    district court and ICA erred in holding that Miranda warnings
    were not required until after she responded to the question.
    V.   Conclusion
    Hewitt’s conviction has already been set aside and the
    charges against her have been dismissed.         It is therefore
    unnecessary to determine when custodial interrogation of Hewitt
    actually commenced.     A remand is no longer appropriate, whether
    on the bases previously ordered by the ICA or to address the
    issues discussed in this opinion.
    17    Sergeant Rose confirmed the truck’s location in some brush and its
    damaged state, which provided an explanation for Hewitt’s injuries and why
    she had dirt and leaves on her person—details Officer Sugata testified to
    noticing about Hewitt’s appearance. Sergeant Rose also found Hewitt’s
    identification card in the truck, and texted a photo of the card to Officer
    Nacino. Except for her injuries, Hewitt matched the image of the person on
    the card. A search of the truck’s license plate number revealed that it was
    registered to a “Cyrus Hewitt,” whom the officers assumed was Hewitt’s
    father.
    30
    Due to the procedural posture of this case, we therefore
    instead reverse the ICA’s March 20, 2021 Judgment on Appeal that
    ordered a remand and affirm the district court’s August 9, 2021
    judgment of nolle prosequi of both counts.
