    SYLLABUS
    Absent application of a specific exception to the warrant requirement, law
    enforcement’s warrantless installation and monitoring of a global positioning system
    mobile tracking device on a target’s vehicle is an unreasonable search requiring
    suppression of the resulting evidence.
    OPINION
    SMITH, JOHN, Judge
    We affirm the district court’s order suppressing evidence and dismissing criminal
    charges against respondent, because law enforcement’s installation and monitoring of a
    global positioning system mobile tracking device on respondent’s vehicle was an
    unreasonable search requiring suppression of the resulting evidence on which evidence the
    charges were based.
    FACTS
    On September 24, 2014, Minnesota Department of Natural Resources Conservation
    Officer Ed Picht submitted to the issuing court a signed and sworn application requesting
    judicial authorization, pursuant to Minn. Stat. § 626A.37 (2014), to covertly install and
    monitor a global positioning system (GPS) mobile tracking device on a truck owned by
    respondent Joshua Dwight Liebl. 1 The application identified Liebl as the person to be
    1
    That statute provides: “Upon an application made under section 626A.36, the court may
    enter an ex parte order authorizing the installation and use of a . . . mobile tracking device
    . . . if the court finds on the basis of the information submitted by the applicant that there
    is reason to believe that the information likely to be obtained by the installation and use is
    relevant to an ongoing criminal investigation.” Minn. Stat. § 626A.37, subd. 1.
    2
    tracked with the GPS device and stated that GPS tracking was for the purpose of
    “collect[ing] information for the investigation of the criminal offenses of: Taking big game
    without a license, trespassing, the unlawful use of artificial lights to take big game, i.e.,
    ‘shining,’ and transporting illegally taken big game.” The application also recited the “facts
    and circumstances” that led Officer Picht to suspect Liebl of these criminal violations of
    Minnesota’s game and fish laws (hunting crimes), including Officer Picht’s receipt of
    multiple citizen reports that implicated Liebl in hunting crimes; Officer Picht’s observation
    of physical evidence, such as blood, deer hair, deer antlers, drag marks, and tire tracks, that
    partially corroborated the citizen reports; and Officer Picht’s knowledge that Liebl’s
    Minnesota hunting privileges had been revoked due to an out-of-state criminal charge of
    “shining deer.” Finally, the application relayed Officer Picht’s belief that using GPS to
    “track[] the movements of [Liebl’s truck] w[ould] facilitate the investigation of [Liebl’s
    suspected hunting crimes] and that the information likely to be obtained by monitoring the
    [GPS] device [would be] relevant to the on-going criminal investigation.” The same day,
    the court issued the requested order (tracking order), which complied with the relevant
    statutory mandates, under Minn. Stat. § 626A.37, subds. 2–4, as to contents, time period
    and extensions, and nondisclosure of such orders.
    About two weeks later, in the early morning hours of October 8, 2014, Conservation
    Officer Jeffery Denz reviewed the tracking order and covertly installed a GPS device on
    Liebl’s truck while it was parked in the driveway of Liebl’s home. From that date until
    October 21, Officer Denz used the GPS device to track the truck’s movements “on a daily
    basis” and “advised [Officer] Picht of any suspicious activity to include times and locations
    3
    when the [truck] was operating after dark and would slow down and stop on gravel roads
    not related to an intersection.” Officer Picht used this information to gather evidence of
    Liebl’s suspected hunting crimes. On October 21, Officer Picht applied for, secured, and
    executed search warrants for Liebl’s home and truck; the warrant applications relied in part
    on Officer Picht’s recitation of evidence resulting from the GPS tracking of Liebl’s truck.
    The searches revealed evidence, including 2 deer carcasses and more than 20 sets of deer
    antlers, that further implicated Liebl in hunting crimes.
    Liebl was arrested and his truck was seized for forfeiture. Appellant State of
    Minnesota    subsequently    charged    Liebl     with   transporting   illegal   big   game,
    taking/possessing big game out of season, hunting big game while under revocation,
    transporting wild animals, using artificial lights to locate animals, hunting big game
    between evening and morning, hunting deer without a license, two counts of failing to tag
    big game (possessing/transporting game in state without tag), two counts of failing to tag
    big game (removing game from site of kill without tag), and two counts of failing to register
    big game.
    Liebl moved to suppress the state’s evidence and to dismiss the charges against him,
    arguing that the evidence resulting from conservation officers’ GPS tracking of his truck
    must be suppressed because the GPS tracking was an unreasonable search under both the
    U.S. and Minnesota Constitutions. Liebl also argued that Minn. Stat. § 626A.42 (2014)
    provided an independent basis for suppression of the evidence resulting from the GPS
    tracking. In opposition, the state denied the applicability of Minn. Stat. § 626A.42 on the
    facts of this case; argued that the GPS tracking was a reasonable search because it was
    4
    conducted in compliance with Minn. Stat. §§ 626A.35–.39 (2014); and alternatively argued
    that, even if the GPS tracking was an unreasonable search, the resulting evidence
    nonetheless was admissible under a good-faith exception to the exclusionary rule. After
    hearing argument, the district court issued an order suppressing all evidence and dismissing
    all charges against Liebl, rejecting Liebl’s section-626A.42 argument but concluding that
    the officers’ GPS tracking of Liebl’s truck violated his rights under U.S. Const. amend. IV
    and that no good-faith exception applied to permit the admission of evidence resulting from
    the violation.
    The state appeals.
    ISSUE
    Was conservation officers’ GPS tracking of Liebl’s truck an unreasonable search
    requiring suppression of the resulting evidence?
    ANALYSIS
    1.        Unreasonable search
    Both the U.S. and Minnesota Constitutions protect “[t]he right of the people to be
    secure in their persons, houses, papers, and effects” by forbidding “unreasonable searches
    and seizures.” U.S. Const. amend. IV; Minn. Const. art. I, § 10. “Under the Fourth
    Amendment to the United States Constitution and Article I, § 10 of the Minnesota
    Constitution, warrantless searches are presumptively unreasonable unless one of a few
    specifically established and well-delineated exceptions applies.” State v. Diede, 
    795 N.W.2d 836
    , 846 (Minn. 2011) (quotations omitted); see also Riley v. California, 
    134 S. Ct. 2473
    , 2482 (2014) (“In the absence of a warrant, a search is reasonable only if it falls
    5
    within a specific exception to the warrant requirement.”). Whether a state action was a
    search, and whether a search was reasonable, are legal questions subject to de novo review.
    State v. Eichers, 
    853 N.W.2d 114
    , 124 (Minn. 2014).
    “[T]he Government’s installation of a GPS device on a target’s vehicle, and its use
    of that device to monitor the vehicle’s movements, constitutes a ‘search’” within the
    meaning of U.S. Const. amend. IV. United States v. Jones, 
    132 S. Ct. 945
    , 949 (2012)
    (footnote omitted). It follows, then, that conservation officers’ GPS tracking of Liebl’s
    truck was an unreasonable search under the U.S. Constitution unless (1) the tracking order
    was legally equivalent to a search warrant, or (2) a specific exception to the warrant
    requirement applies. 2 Cf. United States v. Faulkner, 
    826 F.3d 1139
    , 1144 (8th Cir. 2016)
    (stating that “[p]lacement of a GPS tracking device on a vehicle is a ‘search’ within the
    meaning of the Fourth Amendment, requiring probable cause and a warrant” (citing Jones,
    
    132 S. Ct. at 949
    )).
    The state argues that as a “pre-search judicial authorization of [GPS tracking,] made
    upon a sworn statement that, in fact, [was sufficient to] establish[] probable cause,” the
    2
    We do not suggest that Minn. Const. art. I, § 10, does not provide protection against GPS
    tracking that is at least equivalent to the protection provided by U.S. Const. amend. IV. See
    State v. McBride, 
    666 N.W.2d 351
    , 361 (Minn. 2003) (“While [an appellate court] may
    interpret the Minnesota Constitution to provide more protection than the U.S. Constitution,
    it may not afford less.”). But the district court did not address the Minnesota Constitution
    in its order suppressing the evidence and dismissing the charges against Liebl, instead
    limiting its analysis to the U.S. Constitution. We similarly confine our own analysis here.
    Cf. State v. Sorenson, 
    441 N.W.2d 455
    , 457 (Minn. 1989) (declining to consider search-
    and-seizure issue under Minn. Const. art. I, § 10, and limiting analysis to U.S. Const.
    amend. IV, reasoning that “the question of [the Minnesota Constitution’s] applicability was
    neither adequately briefed nor litigated”).
    6
    tracking order was legally equivalent to a search warrant. We reject the state’s legal-
    equivalency argument because such a holding would be contrary to the U.S. Constitution’s
    requirement that “a warrant may issue only upon a finding of probable cause.” See United
    States v. Ventresca, 
    380 U.S. 102
    , 107, 
    85 S. Ct. 741
    , 745 (1965) (quotation marks
    omitted). Here, there was no finding of probable cause at the time the tracking order was
    issued. 3
    Persuasive authority illustrates this point in the context of GPS tracking. In Keeylen
    v. State, an Indiana appellate court acknowledged that “the police asked for, and received,
    repeated authorizations from the trial court permitting the police to install and monitor GPS
    devices on [the target]’s vehicles” and stated that “it is not dispositive that the trial court’s
    authorizations were not labeled ‘warrants.’” 
    14 N.E.3d 865
    , 875 (Ind. Ct. App. 2014). Yet
    the appellate court qualified that statement, declaring that “[t]he label, nonetheless, is
    significant.” 
    Id.
     (quotation omitted). The court explained:
    The defining features of a judicial search warrant are
    that: (a) it must be issued by a judicial officer; (b) the judicial
    officer must find that there is probable cause to believe that
    evidence of contraband is present in the place to be searched;
    (c) the probable cause finding must be supported by the
    information contained in the oath or affidavit; and (d) the
    warrant must describe with particularity the places to be
    searched and the things to be seized.
    3
    We note that the state did not argue at the district court level that a warrant exception
    applies to conservation officers’ GPS tracking of Liebl’s truck; it thereby forfeited any
    such argument on appeal. See State v. Gauster, 
    752 N.W.2d 496
    , 508 (Minn. 2008)
    (concluding that state forfeited warrant-exception argument by failing to raise it below,
    reasoning that “[appellate courts] generally will not consider arguments raised for the first
    time on appeal”).
    7
    . . . In a typical case, where a putative warrant is labeled
    a “warrant” and explicitly purports to issue under the Fourth
    Amendment’s Warrant Clause, the omission of the term
    “probable cause” from the face of the warrant would not cast
    the slightest doubt on the conclusion that the warrant
    necessarily issued upon a judicial finding of probable cause.
    The reason, simply, is that a warrant, which is labeled a
    “warrant” and that purports to issue under the Fourth
    Amendment, may issue only upon a judicial finding of
    probable cause. The Fourth Amendment requires no more than
    this implied finding.
    In a case where a “warrant” is not sought, however,
    things are quite different. The State argues that there is no
    procedure for authorizing a search based on anything less than
    a showing of probable cause. But it is also true that, [from 2009
    to 2011, when] the trial court issued the authorizations, it was
    not clear that a warrant supported by probable cause was
    required before the installation and use of a GPS tracking
    device. Indeed, it is telling that the officers did not seek a
    “warrant.” Their failure to do so suggests that the officers, by
    merely seeking an order of authorization, sought something
    less than a warrant, and, as is easily inferred, on less than
    probable cause.
    
    Id.
     at 868–70, 875–76 (quotations and citations omitted). The appellate court accordingly
    rejected the state’s argument that officers “substantially complied with th[e warrant]
    requirement by seeking repeated authorizations of the use of the GPS devices from the trial
    court,” and it concluded that “the warrantless installation of the GPS devices and
    monitoring of [the target]’s vehicles was improper.” 
    Id.
     at 875–76, 879.
    In our view, Keeylen’s reasoning is even more compelling in this case, where
    statutes expressly authorized the issuance of a tracking order in the absence of a probable-
    cause finding by the issuing court. See Minn. Stat. § 626A.37, subd. 1 (providing for
    issuance of tracking order on finding “that there is reason to believe that the information
    8
    likely to be obtained by the installation and use is relevant to an ongoing criminal
    investigation”); cf. State v. Fakler, 
    503 N.W.2d 783
    , 786, 789 (Minn. 1993) (rejecting this
    court’s conclusion that Minn. Stat. § 626A.37 requires issuing court to have “some
    articulable reason to believe that [surveillance pursuant to order] will produce probative
    incriminating evidence,” and concluding that all that is required under statute is “precisely
    what it says”).
    Contrary to the state’s assertions on appeal, the district court here did not conclude
    that the tracking order’s “failure . . . to include an express finding of probable cause on its
    face was fatal” to the state’s legal-equivalency argument. Rather, the district court found
    that “[n]o finding of probable cause was requested [of] or made” by the issuing court. The
    state does not allege, much less demonstrate, clear error in the district court’s finding,
    which has ample support in the record. Because the tracking order was not based on a
    probable-cause finding by the issuing court, the tracking order was not a valid substitute
    for a search warrant. Consequently, we reject the state’s legal-equivalency argument and
    conclude that conservation officers’ warrantless GPS tracking of Liebl’s truck was an
    unreasonable search that violated U.S. Const. amend. IV, irrespective of compliance with
    Minn. Stat. §§ 626A.35–.39 and existence of probable cause.
    In support of its legal-equivalency argument, the state cites three nonprecedential
    cases: United States v. Ponce, No. 12-115(3), 
    2012 WL 6771394
     (D. Minn. Dec. 10, 2012)
    (report and recommendation of magistrate judge), adopted by United States v. Ponce, No.
    12-115(3), 
    2013 WL 64607
     (D. Minn. Jan. 4, 2013); State v. Harrington, 
    990 N.E.2d 667
    (Ohio Ct. App. 2013); and Commonwealth v. Burgos, 
    64 A.3d 641
     (Pa. Super. Ct. 2013).
    9
    We consider the persuasive value of Ponce to be slight at best. The issue in Ponce was not
    whether a tracking order may be legally equivalent to a search warrant; rather, the
    magistrate judge considered only “whether probable cause existed” for issuance of a
    tracking order “on the four corners” of the tracking order and the “documents . . . including
    the application in support thereof.” 
    2012 WL 6771394
    , at *8 & n.6.
    While Ponce provides no guidance here, Harrington and Burgos are more directly
    on point. In Harrington, GPS tracking of the target’s vehicle was authorized “via an entry
    signed by a . . . municipal court judge.” 990 N.E.2d at 669. The entry was made after a
    police detective appeared before the judge and “set forth via affidavit his reasons,
    observations, and the facts leading to the request” for GPS tracking. Id. at 670. The
    appellate court concluded that “the trial court did not err in upholding the placement of the
    GPS device pursuant to the entry,” reasoning in part that “[t]he municipal court judge
    reviewed an affidavit that set forth specific facts and observations that clearly met the
    probable cause standard.” Id. at 671, 673.
    The Burgos court similarly concluded that a tracking order that was issued pursuant
    to state statute and supported by probable cause “serve[d] as the functional equivalent of
    [a] traditional search warrant[],” despite the failure to comply with “traditional search
    warrant requirements” as to “the documents upon which the tracking of [the target]’s
    vehicle was grounded and the manner and timing of the execution” of the tracking order. 4
    4
    That statute provided: “An order authorizing the use of one or more mobile tracking
    devices may be issued . . . upon written application” that “provide[s] a statement setting
    forth all facts and circumstances which provide the applicant with a reasonable suspicion
    that criminal activity has been, is or will be in progress and that the use of a mobile tracking
    10
    
    64 A.3d at
    646–47, 652–53 & n.17, 655–56 (quotation omitted). In reaching its conclusion,
    the court emphasized that “t[racking] orders are statutorily prescribed orders, approved and
    issued by the judiciary, which allow an investigating officer to conduct a search . . . upon
    a showing of the requisite level of suspicion.” 
    Id. at 655
    .
    Contrary to the state’s assertions in its briefs and at oral argument, the Burgos and
    Harrington opinions do not make clear that, in those cases, the judicial authorizations of
    GPS tracking were not based on contemporaneous probable-cause findings. In this case,
    by contrast, it is beyond dispute that the tracking order lacked an apparent probable-cause
    finding by the issuing court, although the district court subsequently found that Officer
    Picht’s tracking-order application included “ample information to support a finding of
    probable cause.” Here the state decries “overly formalistic readings of probable-cause
    requirements” as the exaltation of “form over substance” and points to caselaw suggesting
    that a warrant need not “recite an express finding of probable cause” to be valid. But the
    state misses the mark in its focus on the question whether a probable-cause finding must
    be express or implied.
    device will yield information relevant to the investigation of the criminal activity.” 
    18 Pa. Cons. Stat. § 5761
    (c) (2010). In response to Jones, the Pennsylvania legislature amended
    the statute to require probable cause rather than reasonable suspicion. See 
    18 Pa. Cons. Stat. § 5761
    (c) (2014) (providing that tracking-order application must “provide a statement
    setting forth all facts and circumstances which provide the applicant with probable cause
    that criminal activity has been, is or will be in progress and that the use of a mobile tracking
    device will yield information relevant to the investigation of the criminal activity”);
    Burgos, 
    64 A.3d at
    653 n.15 (describing amendment and stating that “it is evident that the
    Legislature recognized the amendment was necessary for Section 5761 to comply with the
    Jones decision”).
    11
    A judicial finding of probable cause is a precondition of a valid warrant. See
    Ventresca, 
    380 U.S. at 107
    , 
    85 S. Ct. at 745
     (stating that “a warrant may issue only upon a
    finding of probable cause” (quotation marks omitted)); United States v. Proell, 
    485 F.3d 427
    , 430 (8th Cir. 2007) (“For a search warrant to be valid, the warrant must be based upon
    a finding by a neutral and detached judicial officer that there is probable cause . . . .”
    (quotation omitted)). It is not enough for post-search analysis to reveal that an issuing court
    could have found probable cause for a search if the court did not find probable cause before
    issuing a search warrant. See United States v. Leppert, 
    408 F.3d 1039
    , 1041 (8th Cir. 2005)
    (stating that “warrants may issue only upon probable cause” and that “[b]efore issuing a
    warrant, a magistrate must determine based on the totality of the circumstances that
    probable cause exists” (quotation omitted)); cf. Messerschmidt v. Millender, 
    132 S. Ct. 1235
    , 1245 (2012) (“[I]t is the magistrate’s responsibility to determine whether the
    officer’s allegations establish probable cause and, if so, to issue a warrant comporting in
    form with the requirements of the Fourth Amendment.” (quotation omitted)). Thus, the
    relevant question here is whether the issuing court made a probable-cause finding at the
    time the tracking order was issued. And, based on the undisputed record, the court did not
    make such a finding before signing the order.
    2.     Suppression of the evidence
    The state urges the application of a federal good-faith exception to the exclusionary
    rule, asserting that Officer Picht believed that warrantless GPS tracking of Liebl’s truck
    was lawful and arguing that Officer Picht’s belief was objectively reasonable in light of the
    tracking order issued pursuant to Minn. Stat. § 626A.37. In support of its argument, the
    12
    state cites United States v. Taylor, 
    979 F.Supp.2d 865
     (S.D. Ind. 2013), aff’d on other
    grounds, 
    776 F.3d 513
     (7th Cir. 2015), a case in which a federal district court declined to
    suppress evidence resulting from the warrantless GPS tracking of a vehicle based on police
    officers’ objectively reasonable reliance on judicial authorization of the GPS tracking.
    But in Taylor, the warrantless GPS tracking took place in September and October
    2011, months prior to Jones’s release in January 2012. 979 F.Supp.2d at 867; see Jones,
    
    132 S. Ct. at 945
    . Here, by contrast, the warrantless GPS tracking took place in October
    2014, nearly three years after Jones’s release. And while the state is correct that Jones did
    not directly hold that a warrant is required for GPS tracking of a target’s vehicle, “Jones
    fundamentally altered th[e pre-Jones] legal landscape,” United States v. Katzin, 
    769 F.3d 163
    , 181 (3d Cir. 2014), by “settl[ing] that the attachment of a GPS device to a car, and
    subsequent use of that device to monitor the car’s movements, is a ‘search,’ and that
    installing such a device without a warrant violates the Fourth Amendment,” United States
    v. Davis, 
    750 F.3d 1186
    , 1189 (10th Cir. 2014) (citation omitted). See also Faulkner, 826
    F.3d at 1145 (stating that “Jones . . . stands for the proposition that placement of a GPS
    device on an automobile requires a warrant”); cf. Katzin, 769 F.3d at 168, 170
    (“caution[ing] that, after Jones, law enforcement should carefully consider that a warrant
    may be required when engaging in [GPS tracking of a vehicle]”).
    The state has not cited a single case that applies a federal good-faith exception to
    preserve the admissibility of evidence that, like the evidence at issue in this case, was
    obtained through post-Jones warrantless GPS tracking of a vehicle. Our own research has
    revealed no such case; instead, we have found cases suggesting that courts will not find
    13
    good faith in facts involving post-Jones warrantless GPS tracking. See, e.g., Taylor, 776
    F.3d at 517 (stating that “[the] good-faith exception [under Davis v. United States, 
    564 U.S. 229
    , 
    131 S. Ct. 2419
     (2011)] . . . applies to pre-Jones use of GPS devices to track a
    suspect’s car based on earlier Supreme Court precedent”); United States v. Aguiar, 
    737 F.3d 251
    , 255, 262 (2d Cir. 2013) (“[S]ufficient Supreme Court precedent existed [in
    January 2009 when] the GPS device was placed for the officers here to reasonably conclude
    a warrant was not necessary in these circumstances. Plainly, post-Jones, the landscape has
    changed, and law enforcement will need to change its approach accordingly.”); United
    States v. Sparks, 
    711 F.3d 58
    , 62 (1st Cir. 2013) (stating that “the [warrantless GPS
    tracking] at issue in recent cases occurred pre-Jones, allowing the government to argue,
    and a number of courts to find, that the good-faith exception would apply even if the
    searches were unconstitutional”).
    We conclude that Jones forecloses the possibility of objectively reasonable, good-
    faith reliance on (1) judicial authorization of GPS tracking of a vehicle that is not based on
    a contemporaneous probable-cause finding, (2) statutes providing for judicial authorization
    of GPS tracking of a vehicle on less than probable cause, and (3) pre-Jones caselaw
    permitting warrantless GPS tracking of a vehicle. Cf. Illinois v. Krull, 
    480 U.S. 340
    , 355,
    
    107 S. Ct. 1160
    , 1170 (1987) (stating that “a law enforcement officer [cannot] be said to
    have acted in good-faith reliance upon a statute if its provisions are such that a reasonable
    officer should have known that the statute was unconstitutional”); United States v. Leon,
    
    468 U.S. 897
    , 922–23, 
    104 S. Ct. 3405
    , 3420 (1984) (stating that “the officer’s reliance on
    the magistrate’s probable-cause determination and on the technical sufficiency of the
    14
    warrant he issues must be objectively reasonable” and that “it is clear that in some
    circumstances the officer will have no reasonable grounds for believing that the warrant
    was properly issued” (footnote omitted)); United States v. Barraza-Maldonado, 
    732 F.3d 865
    , 867 (8th Cir. 2013) (“For the good faith exception to apply, officers performing a
    particular investigatory action—such as GPS tracking—must strictly comply with binding
    appellate precedent governing the jurisdiction in which they are acting.” (citing Davis, 
    564 U.S. at 240
    , 
    131 S. Ct. at 2428
    )).
    The state also appears to argue that Officer Picht’s belief in the lawfulness of
    warrantless GPS tracking of Liebl’s truck was objectively reasonable because of the post-
    Jones “pattern and practice” regarding warrantless tracking devices in Minnesota—i.e.,
    law enforcement’s continued use of Minn. Stat. § 626A.36 to apply for judicial
    authorization of tracking orders, courts’ continued issuance of tracking orders pursuant to
    Minn. Stat. § 626A.37, and the legislature’s failure to amend or repeal those statutes. But
    as articulated by amicus curiae American Civil Liberties Union of Minnesota, “the failure
    of state actors to conform to a newly announced rule of constitutional criminal procedure
    should never insulate that conduct from constitutional scrutiny.”
    In sum, Officer Picht lacked an objectively reasonable basis for his belief that
    warrantless GPS tracking of Liebl’s truck was constitutionally permissible after Jones. We
    believe that the exclusionary rule’s deterrence rationale was served here, because law
    enforcement has a duty to stay abreast of changes in the law. We therefore decline the
    state’s invitation to apply a federal good-faith exception in this case and conclude that
    15
    conservation officers’ warrantless GPS tracking of Liebl’s truck was an unreasonable
    search requiring suppression of the resulting evidence.
    We note that Liebl argues that suppression of the evidence resulting from
    conservation officers’ warrantless GPS tracking of his truck also was mandated by Minn.
    Stat. § 626A.42. 5 The district court rejected Liebl’s interpretation of that statute, reasoning
    that “[it] was intended to apply to devices already in the possession of an individual.” In
    light of our conclusion that the GPS tracking was an unreasonable search requiring
    suppression of the evidence, we do not reach the section-626A.42 issue here.
    DECISION
    Because conservation officers’ GPS tracking of Liebl’s truck was a warrantless
    search to which no warrant-requirement exception applies and to which the good-faith
    exception does not apply, the district court did not err in suppressing the evidence that
    resulted from the GPS tracking and dismissing the criminal charges that were based on the
    suppressed evidence.
    Affirmed.

    That statute provides: “[A] government entity may not obtain the location information of
    an electronic device without a tracking warrant. A warrant granting access to location
    information must be issued only if the government entity shows that there is probable cause
    the person who possesses an electronic device is committing, has committed, or is about to
    commit a crime.” Minn. Stat. § 626A.42, subd. 2(a). Evidence obtained in violation of
    section 626A.42 is not admissible “in any criminal, civil, administrative, or other
    proceeding.” Id., subd. 6(a).
