BRODY, Justice.
Desiree Elaine Karst appeals the district court’s partial denial of her motion to suppress
evidence obtained during a traffic stop. Karst asserts the police sergeant impermissibly extended
the traffic stop when he briefly interrupted his traffic-related investigation to contact dispatch and
request a drug-dog unit at the scene. The Court of Appeals affirmed the district court’s decision,
citing its recent decision in State v. Still, 166 Idaho 351, 458 P.3d 220 (Ct. App. 2019). This Court
granted Karst’s petition for review. We overrule Still, reverse the district court’s decision, and
remand this case for further proceedings.
I. FACTUAL AND PROCEDURAL BACKGROUND
On November 29, 2017, Sergeant Jeremy Hyle with the Kootenai County Sheriff’s Office
stopped a truck outside Post Falls, Idaho, for multiple minor traffic violations. Sergeant Hyle

1
observed two occupants in the vehicle, whom he later identified as Jeremy Guydos and Desiree
Elaine Karst. Karst was seated in the passenger seat and was not wearing a seatbelt. Sergeant Hyle
requested Guydos’ license, registration, and insurance. Sergeant Hyle also requested Karst’s
information. She responded verbally but did not produce any form of identification.
As Sergeant Hyle started to return to his patrol vehicle, he stopped and radioed dispatch to
request that a drug-dog unit respond to the scene. According to Sergeant Hyle at the hearing on
the motion to suppress, he requested a drug-dog unit because the truck was coming from a
suspected drug location and the Guydos’ name had come up in connection with drug
investigations:
the house the truck was coming from in the beginning was the suspected drug
location that [officers] had intel on, and Mr. Guydos—I actually recognized his
name when I met him or when I contacted him that night, that his name had come
up in drug investigations and drug intel previously, and then based on the
movement that he made, leaning over towards Ms. Karst, that’s common with
people trying to either obtain or conceal a weapon or evidence of contraband of
some sort, and based on all that I wanted [a drug-dog unit] to come run the truck
with [a] canine.
The time it took to request the drug-dog unit was about nineteen seconds. After that request,
Sergeant Hyle then asked dispatch to run a warrants check on the occupants and returned to his
vehicle.
Once Sergeant Hyle returned to his vehicle to write a no seatbelt citation for Karst, he
entered her information into his computer system. As he was gathering information, dispatch
relayed that Guydos had a suspended Idaho license. Based on this new information, Sergeant Hyle
contacted Guydos a second time to ask about the suspended Idaho license. During this inquiry,
Sergeant Hyle discovered Guydos did not have insurance on the vehicle.
Sergeant Hyle returned to his patrol vehicle again, this time to write citations against
Guydos for driving without privileges and no insurance. At this time, the drug-dog unit arrived at
the scene and conducted a dog sniff around the vehicle. Sergeant Hyle completed the citations for
Guydos and returned to the no seatbelt citation for Karst when he realized he needed more
information from her. Sergeant Hyle exited his patrol vehicle to give the citations to Guydos at the
same time the drug dog alerted on the truck.
After the alert, Sergeant Hyle learned Karst admitted to having marijuana in the vehicle,
so he shifted his focus to investigating Karst further. When Sergeant Hyle asked Karst to exit the

2
vehicle, she stalled and began shifting items around on her lap. Sergeant Hyle requested Karst
hand over anything on her lap, which led to the discovery of a small tin containing
methamphetamine. Upon further search of Karst’s pockets, Sergeant Hyle found marijuana and
paraphernalia. Karst was later arrested and transported to the county jail where more marijuana
and paraphernalia were discovered on her person.
Karst was charged with possession of methamphetamine, possession of marijuana,
possession of drug paraphernalia, and introducing major contraband into a correctional facility.
Karst moved to suppress the drug and paraphernalia evidence. Karst initially challenged the
legality of the stop, but subsequently conceded it was legal. Karst also argued Sergeant Hyle
unlawfully extended the traffic stop and impermissibly searched her. The district court denied
Karst’s suppression motion in part. First, the district court found Sergeant Hyle did not unlawfully
prolong the traffic stop:
[Sergeant] Hyle did not “drag his feet,” as [Karst] argued, to gain time for the dog
to arrive. The investigation of the traffic violations was somewhat complicated
given the unusual circumstances of Guydos having a suspended Idaho license along
with a valid Florida license, and the fact that Guydos gave some conflicting and
confusing answers to some of Hyle’s questions. Hyle diligently and thoroughly
investigated these violations and meticulously prepared citations for them, all of
which took a considerable amount of time. He did not prolong the stop to effectuate
the dog sniff. Rather, he continued working on the investigation/citations both
before and after the dog arrived. He did not appear to be wasting time and walked
quickly between his patrol car and the truck on the few occasions he did so.
As a result, the district court ruled that the methamphetamine found in the tin should not be
suppressed. However, the district court held the additional search of Karst’s pocket was unlawful
and suppressed the marijuana and paraphernalia evidence found there.
Thereafter, Karst entered conditional guilty pleas pursuant to Idaho Criminal Rule 11(a)(2).
The State agreed to dismiss the introduction of major contraband charge, while Karst conditionally
pleaded guilty to the possession of methamphetamine charge, the possession of marijuana charge,
and the possession of drug paraphernalia charge. The possession of marijuana and paraphernalia
charges were based on items found on Karst at the jail, not the items found in her pocket which
were suppressed. The district court accepted Karst’s guilty pleas and sentenced Karst to four years
in the penitentiary, with two years fixed, for possession of methamphetamine. She was sentenced
to time served on the other charges. The district court suspended her sentence and placed her on
probation for two years. Karst timely appealed the district court’s partial denial of her motion to

3
suppress. The Idaho Court of Appeals affirmed the district court’s decision. This Court granted
Karst’s petition for review.
II. STANDARD OF REVIEW
“When reviewing a case on petition for review from the Court of Appeals this Court gives
due consideration to the decision reached by the Court of Appeals, but directly reviews the decision
of the trial court.” State v. Gonzales, 165 Idaho 667, 671, 450 P.3d 315, 319 (2019) (quoting State
v. Schmierer, 159 Idaho 768, 770, 367 P.3d 163, 165 (2016)).
When reviewing a motion to suppress, the standard is bifurcated. Id. “[T]his Court will
defer to the trial court’s factual findings unless clearly erroneous. However, free review is
exercised over a trial court’s determination as to whether constitutional requirements have been
satisfied in light of the facts found.” State v. Samuel, 165 Idaho 746, 755, 452 P.3d 768, 777 (2019)
(quoting State v. Doe, 137 Idaho 519, 522, 50 P.3d 1014, 1017 (2002)).
IV. ANALYSIS
Karst argues the district court erred when it denied her motion to suppress because Sergeant
Hyle impermissibly extended the traffic stop when he stopped for nineteen seconds on the way
back to his vehicle to contact dispatch and request a drug-dog unit. Although the deviation was
slight, Karst maintains the deviation from the traffic stop’s mission constituted a violation of her
Fourth Amendment right to be free from unreasonable seizures. We agree with Karst.
Karst’s challenge calls on us to once again decide how to interpret the United States
Supreme Court’s decision in Rodriguez v. United States, 575 U.S. 348 (2015). We attempted to
settle the issue in State v. Linze, 161 Idaho 605, 389 P.3d 150 (2016), but since that case was
decided, the boundaries of its precedent have been tested in State v. Pylican, 167 Idaho 745, 755,
477 P.3d 180, 190 (2020), reh’g denied (Oct. 1, 2020) (distinguishing Linze because the district
court made no findings that any specific amount of time was added to the traffic stop in connection
with the dog sniff) and State v. Hale, 168 Idaho 863, 868, 489 P.3d 450, 455 (2021) (holding that
the officer’s questioning regarding permission to operate a vehicle was an ordinary inquiry
incident to the traffic stop). The Idaho Court of Appeals has, likewise, had to contend with
continued challenges, most notably deciding State v. Still, 166 Idaho 351, 458 P.3d 220 (Ct. App.
2019), the precedent it relied upon in this case to affirm the district court’s decision.
There clearly is a difference in how this Court and the Idaho Court of Appeals interpret
Rodriguez and Linze. That difference stems from the word “abandonment”—a term introduced
4
during our analysis in Linze. Today we reiterate that the proper focus of this case, and cases like
it, is whether the dog sniff “prolonged” or “added time to” the traffic stop. Whether the officer
“abandoned” the traffic stop is not determinative. We also reiterate that there is no de minimis
intrusion justification for prolonging a traffic stop. As we said in Linze, the rule of law announced
by the Supreme Court of the United States in Rodriguez is broad and inflexible. 161 Idaho at 608,
389 P.3d at 153. Unless, and until, Rodriguez is overruled, this Court is bound to apply the
precedent.
Let us start, again, from the beginning.
A. Unlawful extension of a traffic stop occurs when an officer’s detour prolongs, or adds
time to, the original purpose for the stop.
“The right of the people to be secure in their persons, houses, papers, and effects, against
unreasonable searches and seizures, shall not be violated[.]” U.S. CONST. amend. IV. When a
motorist is pulled over for a traffic violation, a “seizure” occurs, and the motorist is entitled to the
protection of the Fourth Amendment. See Rodriguez, 575 U.S. at 354. A traffic-related seizure
violates the Fourth Amendment if it is prolonged beyond the time reasonably required to complete
the “mission” of issuing a ticket. Id. at 350–51.
In Rodriguez, a K-9 officer pulled over a motorist for driving on the shoulder of a Nebraska
highway. Id. at 348. After the officer issued a warning, the officer asked for permission to walk
his dog around the driver’s vehicle. Id. at 352. After the driver said “no,” the officer instructed him
to exit the vehicle, waited for a second officer to arrive, and then retrieved his dog and led him
around the vehicle. Id. The dog alerted, and a subsequent search of the vehicle led to the discovery
of a large bag of methamphetamine. Id. All of this prolonged the stop about seven to ten minutes.
Id. at 353. The driver was subsequently charged with possession with intent to deliver. Id.
Rodriguez filed a motion to suppress the drug evidence, arguing the K-9 officer
unreasonably prolonged the traffic stop in order to conduct the dog sniff without reasonable
suspicion that a crime had been or was about to be committed. Id. at 352. The federal district court
denied Rodriguez’s motion, concluding that “dog sniffs that occur within a short time following
the completion of a traffic stop are not constitutionally prohibited if they constitute only de
minimis intrusions.” Id. at 353 (quoting United States v. Alexander, 448 F.3d 1014, 1016 (8th Cir.
2006)). The United States Court of Appeals for the Eighth Circuit agreed, holding that the delay
constituted an acceptable “de minimis” intrusion on Rodriguez’s personal liberty. Id. The Supreme

5
Court of the United States granted certiorari to resolve a division among lower courts on the issue.
Id. at 353–54.
The Supreme Court, in ruling in favor of Rodriguez, explained that a traffic stop is more
analogous to a Terry stop than a formal arrest and that the constitutionally permissible duration of
the stop is determined by the seizure’s “mission”:
A seizure for a traffic violation justifies a police investigation of that
violation. “[A] relatively brief encounter,” a routine traffic stop is “more analogous
to a so-called ‘Terry stop’ . . . than to a formal arrest.” Knowles v. Iowa, 525 U.S.
113, 117 (1998) (quoting Berkemer v. McCarty, 468 U.S. 420, 439 (1984), in turn
citing Terry v. Ohio, 392 U.S. 1 (1968)). See also Arizona v. Johnson, 555 U.S.
323, 330 (2009). Like a Terry stop, the tolerable duration of police inquiries in the
traffic-stop context is determined by the seizure’s “mission”—to address the traffic
violation that warranted the stop, [Illinois v. Caballes, 543 U.S. 405, 407 (2005)],
and attend to related safety concerns. See also United States v. Sharpe, 470 U.S.
675, 685 (1985); Florida v. Royer, 460 U.S. 491, 500 (1983) (plurality opinion)
(“The scope of the detention must be carefully tailored to its underlying
justification.”). Because addressing the infraction is the purpose of the stop, it may
“last no longer than is necessary to effectuate th[at] purpose.” Ibid. See
also Caballes, 543 U.S. at 407. Authority for the seizure thus ends when tasks tied
to the traffic infraction are—or reasonably should have been—completed.
See Sharpe, 470 U.S. at 686 (in determining the reasonable duration of a stop, “it
[is] appropriate to examine whether the police diligently pursued [the]
investigation”).
Rodriguez, 575 U.S. at 354 (alterations in original) (internal citations omitted).
The Supreme Court explained that an officer’s mission when conducting a traffic stop
includes ordinary inquiries such as checking the driver’s license, checking for outstanding
warrants, and inspecting the vehicle’s registration and proof of insurance. Id. at 355 (citing cases).
The Rodriguez Court also made it clear that an “[a]n officer . . . may conduct certain unrelated
checks during an otherwise lawful traffic stop. But . . . he may not do so in a way that prolongs the
stop, absent the reasonable suspicion ordinarily demanded to justify detaining an individual.” 575
U.S. at 355 (internal citation omitted). The Supreme Court explained that a dog sniff “is a measure
aimed ‘at detect[ing] evidence of ordinary criminal wrongdoing.’ ” Id. (quoting Indianapolis v.
Edmond, 531 U.S. 32, 40–41 (2000)). Thus, “a dog sniff is not fairly characterized as part of the
officer’s traffic mission.” Rodriguez, 575 U.S. at 356. As a result, the Supreme Court held “a police
stop exceeding the time needed to handle the matter for which the stop was made violates the
Constitution’s shield against unreasonable seizures” because “[a] seizure justified only by a police-
observed traffic violation . . . ‘become[s] unlawful if it is prolonged beyond the time reasonably
6
required to complete th[e] mission’ of issuing a ticket for the violation.” Id. at 350 (alterations in
original) (quoting Caballes, 543 U.S. at 407).
Not long after Rodriguez was decided, this Court confronted a Fourth Amendment
challenge in a situation where a drug-dog sniff occurred during the traffic stop instead of after the
stop was completed. See State v. Linze, 161 Idaho 605, 389 P.3d 150 (2016). In Linze, an officer
stopped a vehicle for a cracked front windshield. Id. at 606, 389 P.3d at 151. After starting warrant
checks on the occupants, the officer called for a drug-dog unit. Id. When the drug-dog unit arrived,
the officer stopped writing the citation and running the warrant checks and began performing a
“backup function” for the officer conducting the dog sniff. Id. at 607, 389 P.3d at 152. This Court
recognized the holding in Rodriguez was not confined to cases involving dog sniffs done after a
completed traffic stop, but rather had a “broad” reach and was “inflexible”:
The United States Supreme Court framed the question before it as “whether
police routinely may extend an otherwise-completed traffic stop, absent reasonable
suspicion, in order to conduct a dog sniff.” [Rodriguez, 575 U.S. at 353]. However,
the United States Supreme Court did not restrict its analysis to cases in which the
underlying purpose of the traffic stop was completed prior to a drug dog sweep. Id.
Instead, the United States Supreme Court reached a much broader holding: “a
police stop exceeding the time needed to handle the matter for which the stop was
made violates the Constitution’s shield against unreasonable seizures.” Id. This
rule is both broad and inflexible. It applies to all extensions of traffic stops
including those that could reasonably be considered de minimis. Id. at [356]
(rejecting the application of a de minimis exception previously adopted by the
Eighth Circuit).
Linze, 161 Idaho at 608, 389 P.3d at 153 (emphasis added) (internal citations omitted).
In framing the legal issue in Linze, the Court explained that the parties had two competing
interpretations of Rodriguez:
The parties before this Court have suggested two competing interpretations
of the United States Supreme Court’s holding in Rodriguez. The State suggests
that Rodriguez allows a seizing officer to deviate from the purpose of a traffic stop
up until the time at which the stop should have been reasonably completed. In other
words, for each traffic stop there is an objective amount of time within which that
stop should reasonably be completed and any unrelated action taken by an officer
within that amount of time does not violate the seized parties’ Fourth Amendment
rights.
Conversely, Mr. Linze reasons that a deviation from the original purpose of
a traffic stop will inevitably lengthen the time needed to complete the original
purpose of the seizure, and, accordingly, will result in a stop that “exceed[s] the
time needed to handle the matter for which the stop was made.” Under Mr. Linze’s

7
 suggested interpretation, the timing of an officer’s departure from the original
purpose of the seizure is irrelevant, it only matters that the officer departed from
that purpose.
Linze, 161 Idaho at 608, 389 P.3d at 153.
In deciding whose interpretation of Rodriguez was correct—the State’s or Linze’s—the
Court adopted Linze’s interpretation that “the timing of an officer’s departure from the original
purpose of the seizure is irrelevant, it only matters that the officer departed from that purpose.” Id.
(emphasis added). This Court explained:
The stop remains a reasonable seizure while the officer diligently pursues the
purpose of the stop, to which that reasonable suspicion is related. However, should
the officer abandon the purpose of the stop, the officer no longer has that original
reasonable suspicion supporting his actions. Indeed, when an officer abandons his
or her original purpose, the officer has for all intents and purposes initiated a new
seizure with a new purpose; one which requires its own reasonableness under the
Fourth Amendment. The new seizure cannot piggy-back on the reasonableness of
the original seizure. In other words, unless some new reasonable suspicion or
probable cause arises to justify the seizure’s new purpose, a seized party’s Fourth
Amendment rights are violated when the original purpose of the stop is abandoned
(unless that abandonment falls within some established exception).
Id. at 609, 389 P.3d at 154 (emphasis added). Ultimately, the Court held the officer violated Linze’s
Fourth Amendment rights “by delaying the traffic stop for two and a half minutes while performing
a back-up function for a drug dog sweep.” Id.
B. The Court of Appeals’ decision in State v. Still, 166 Idaho 351, 458 P.3d 220 (Ct. App.
2019) improperly required “abandonment” of the traffic mission for a stop to become
unlawfully extended.
Focusing on the “abandonment” language emphasized above, the Idaho Court of Appeals
recently narrowed Linze’s reach when it held that an officer did not unlawfully prolong a traffic
stop when the officer made a ten-second radio call for a drug-dog unit. State v. Still, 166 Idaho
351, 356–57, 458 P.3d 220, 225–26 (Ct. App. 2019). Karst urges this Court to overturn Still,
arguing it is “manifestly wrong due to its conflict with Fourth Amendment precedent from the
United States Supreme Court and Idaho on the scope of an officer’s permissible conduct during a
routine traffic stop.”
In Still, two officers stopped a vehicle and requested the driver’s license, registration, and
proof of insurance. Id. at 352, 458 P.3d at 221. Still provided his license and while he was searching
for his registration and proof of insurance, one of the officers called for a drug-dog unit using his
on-body radio. Id. Still provided his registration and proof of insurance and the officers returned
8
to their patrol vehicle to run the documents through their system. Id. Once they returned to their
patrol vehicle, the same officer radioed for the drug-dog unit a second time, which took about ten
seconds. Id. at 352–53, 458 P.3d at 221–22. Afterwards, the officers began processing Still’s
information and completing a citation for speeding. Id. at 353, 458 P.3d at 222. While completing
the citation, the drug-dog unit arrived and alerted on the vehicle. Id. A search led to the finding of
contraband. Id. Still was ultimately charged with unlawful possession of a firearm and unlawful
possession of methamphetamine. Id. Still sought to suppress the evidence found in the vehicle, but
the district court denied the motion. Id.
On appeal, Still argued the “traffic stop was unlawfully extended in violation of the Fourth
Amendment when [the officer] radioed to [a drug-dog unit] a second time.” Id. at 354, 458 P.3d at
223. According to Still, the drug-dog unit request “constituted an abandonment of the traffic
mission because it was unrelated to the purpose of the stop and ‘added time’ to Still’s detention
making it an unreasonable seizure under the Fourth Amendment.” Id. The Court of Appeals
disagreed, explaining, “an abandonment occurs when officers deviate from the purpose of the
traffic mission in order to investigate, or engage in safety measures aimed at investigating crimes
unrelated to roadway safety for which the officers lack reasonable suspicion.” Id. at 356, 458 P.3d
at 225 (citing Rodriguez, 575 U.S. at 354–57; Linze, 166 Idaho at 609, 389 P.3d at 154). Applying
this rule, and the “Fourth Amendment’s reasonableness requirement,” the court narrowed the issue
to “whether a radio call to inquire if a drug-dog unit is available constitutes an abandonment of the
traffic mission so as to amount to an unlawful extension of [a] traffic stop.” Still, 166 Idaho at 356,
458 P.3d at 225. The court noted that Still “challenge[d] the radio call to the drug-dog officer.” Id.
But, the officer who made the radio call did not conduct the drug-dog sniff, did not take safety
measures aimed at conducting the drug-dog sniff, or engage in any other alternate investigation.
Id. Thus, the court opined: “[a]t most, a radio call to inquire if a drug-dog unit is available is a
precursor to an alternate investigation” but “the call itself does not amount to a Fourth Amendment
violation.” Id. The court ultimately held that its decision “comport[ed] with Rodriguez and Linze.”
Still, 166 Idaho at 356, 458 P.3d at 225. The court stated that “any pause during a traffic stop” does
not lead to the conclusion under Rodriguez and Linze that the officers abandoned the purpose of
the traffic stop. “In fact, [the court concluded,] such a conclusion is inimical to the Fourth
Amendment’s reasonableness requirement,” and that a holding to the contrary would be “contrary

9
to United States Supreme Court precedent.” Id. Ultimately, the court affirmed the denial of Still’s
motion to suppress after finding Still’s detention had not been unlawfully extended. Id.
We agree with Karst that Still conflicts with the holdings of Rodriguez and Linze and must
be overruled. Going back to Linze, the Court held that Linze’s interpretation of Rodriguez was
correct, and, in doing so, introduced the concept of “abandonment” which the Idaho Court of
Appeals then used to affirm the denial of Still’s motion to suppress:
We hold that Mr. Linze’s interpretation of Rodriguez is correct. The United
States Supreme Court has plainly established that a traffic stop is a seizure, but it is
not an unreasonable seizure under the Fourth Amendment so long as there is a
reasonable suspicion that the vehicle is being driven contrary to traffic laws. United
States v. Cortez, 449 U.S. 411, 417 (1981). The stop remains a reasonable seizure
while the officer diligently pursues the purpose of the stop, to which that reasonable
suspicion is related. However, should the officer abandon the purpose of the stop,
the officer no longer has that original reasonable suspicion supporting his actions.
Indeed, when an officer abandons his or her original purpose, the officer has for all
intents and purposes initiated a new seizure with a new purpose; one which requires
its own reasonableness under the Fourth Amendment. This new seizure cannot
piggy-back on the reasonableness of the original seizure. In other words, unless
some new reasonable suspicion or probable cause arises to justify the seizure’s new
purpose, a seized party’s Fourth Amendment rights are violated when the original
purpose of the stop is abandoned (unless that abandonment falls within some
established exception).
Linze, 161 Idaho at 609, 389 P.3d at 154 (internal citation omitted).
Right on the heels of this discussion, the Court reinforced the merits of Linze’s
interpretation by explaining that the focus of Rodriguez is whether an officer’s deviation from the
original purpose of a traffic stop “adds time to” the traffic stop:
Further enforcing the merits of Mr. Linze’s interpretation of Rodriguez is
the fact that the State’s proposed interpretation cannot be reconciled with the United
States Supreme Court’s analysis. In Rodriguez, the United States Supreme Court
explicitly rejected an argument advanced by the Government that “by completing
all traffic-related tasks expeditiously, an officer can earn bonus time to pursue an
unrelated criminal investigation.” ––– U.S. at ––––, 135 S.Ct. at 1616, 191 L.Ed.2d
at 500–01. The gist of this argument was that because there is a set “reasonable”
amount of time for each stop, any officer who completes his or her duties under that
amount of time can pursue unrelated investigations. In rejecting this argument, the
United States Supreme Court noted that “an officer always has to be reasonably
diligent.” Id. The United States Supreme Court reasoned that “[i]f an officer can
complete traffic based inquiries expeditiously, then that is the amount of time
reasonably required to complete the stop’s mission.” Id. (internal citations
omitted). The United States Supreme Court concluded that “the critical question,
then, is not whether the dog sniff occurs before or after the officer issues a ticket ...
10
 but whether conducting the sniff ‘prolongs’—i.e., adds time to—‘the stop’ ” Id. The
United States Supreme Court’s intention in Rodriguez is thus made clear. The rule
isn’t concerned with when the officer deviates from the original purpose of the
traffic stop, it is concerned with the fact that the officer deviates from the original
purpose of the stop at all.1 The State’s interpretation of Rodriguez violates the
United States Supreme Court’s underlying conclusion that “an officer always has
to be reasonably diligent.” Id.
State v. Linze, 161 Idaho 605, 609, 389 P.3d 150, 154 (2016) (emphasis added).
The footnote referenced in this passage explained that a dog sniff conducted by a second
officer while the first officer pursues the traffic stop does not “add time” to the stop:

The United States Supreme Court is careful to couch its opinion in the “adds time
to” framework. It does this in order to allow for dog sniffs that do not add time to
the stop (i.e., dog sniffs in which one officer continues to pursue the original
objectives of the stop while a second officer conducts a dog sniff).
State v. Linze, 161 Idaho 605, 609, 389 P.3d 150, 154 (2016).
While the concept of “abandonment” originated in Linze, the Idaho Court of Appeals’
decision in Still fundamentally and impermissibly altered the holding of Rodriguez. Nowhere does
the majority in Rodriguez use—or apply—the concept of “abandonment” to reach its rule. See
Rodriguez, 575 U.S. 354–58. We explained in Linze, and we say it again today, that the critical
question according to Rodriguez is whether the dog sniff “prolonged” or “added time” to the
overall duration of the traffic stop. Contrary to Still, the officer does not have to “abandon” the
mission of the traffic stop for a Fourth Amendment violation to occur. Merely “detouring” (the
word used in Rodriguez) or “deviating” (the word used in Linze) from that mission, even if the
delay is de minimis, runs afoul of the protections of the Fourth Amendment.
Here, after making the traffic stop and initially contacting Karst and the driver, Sergeant
Hyle began walking back towards his patrol vehicle. However, instead of continuing activities
related to the traffic stop’s mission, Sergeant Hyle spent approximately nineteen seconds on his
radio with dispatch to request a drug-dog unit. That detour added time to, or prolonged, completing
the original purpose for the stop. The fact that Karst was held for a mere nineteen seconds more
than she should have been matters not for Fourth Amendment purposes—there is no exception for
unjustified de minimus intrusions. See Linze, 161 Idaho at 608, 389 P.3d at 153; Rodriguez, 575
U.S. at 356–57.
While the dissent makes a forceful case for how Karst’s challenge ought to be analyzed
under the Fourth Amendment, its arguments echo those of the dissents in Rodriguez. Justice
11
Thomas made the case that the majority’s rule in Rodriguez ignored the touchstone of the Fourth
Amendment inquiry—“reasonableness”—because the overall duration of the stop was reasonable
when only twenty-nine minutes passed from the time the officer stopped Rodriguez until the drug
dog alerted to the presence of drugs:
Because Rodriguez does not dispute that Officer Struble had probable cause
to stop him, the only question is whether the stop was otherwise executed in a
reasonable manner. . . . I easily conclude that it was. Approximately 29 minutes
passed from the time Officer Struble stopped Rodriguez until his narcotics-
detection dog alerted to the presence of drugs. That amount of time is hardly out of
the ordinary for a traffic stop by a single officer of a vehicle containing multiple
occupants even when no dog sniff is involved. [Citing cases where the traffic stops
took 22 and 30 minutes.] . . . . The stop here was “lawful at its inception and
otherwise executed in a reasonable manner[ ]” . . . . thus, no Fourth Amendment
violation occurred.
575 U.S. at 361 (Thomas, J., dissenting) (internal citations omitted).
Here, the dissent relies on an interpretation of the Fourth Amendment which would find no
violation if the traffic stop’s overall duration was “reasonable”—notwithstanding unjustified
intrusions that objectively “prolong” or “add time to” the stop:
Additionally, the inflexibility further etched into the Fourth Amendment by
the majority today cannot coexist with the reasonableness that Amendment
demands. “[T]he ultimate touchstone of the Fourth Amendment is
‘reasonableness.’ ” Brigham City v. Stuart, 547 U.S. 398, 403 (2006).
The dissent’s position was soundly rejected by a majority of the Supreme Court of the United
States in Rodriguez. See 575 U.S. at 355–58. The majority in Rodriguez made it clear that the
Fourth Amendment does not permit officers to earn “bonus time” to engage in unjustified
intrusions whenever they complete “all traffic-related tasks expeditiously[.]” Id. at 357. Likewise,
it does not demand demerits when an officer sneezes or searches for a pen. “Authority for the
seizure thus ends when tasks tied to the traffic infraction are—or reasonably should have been—
completed.” Rodriguez, 575 U.S. at 354. Unless, and until, that Court overrules Rodriguez, this
Court is obliged to follow the precedent. See James v. City of Boise, Idaho, 577 U.S. 306, 307
(2016) (“The Idaho Supreme Court, like any other state or federal court, is bound by this Court’s
interpretation of federal law.”).
Thus, we hold Sergeant Hyle impermissibly extended the duration of the traffic stop when
he requested the drug-dog unit, in violation of the Fourth Amendment. We reverse the district

12
court’s denial of Karst’s motion to suppress and remand this case to the district court for further
proceedings.
V. CONCLUSION
The district court’s partial denial of Karst’s motion to suppress is reversed, and this case is
remanded to the district court for further proceedings.
Justices STEGNER and MOELLER, CONCUR.

BEVAN, Chief Justice, dissenting:
I respectfully dissent from the conclusion reached by the majority that a nineteen-second
pause to request a drug-dog unit and hear back from dispatch constitutes a violation of the Fourth
Amendment. In reaching its decision the Court diminishes the reasoning of Idaho’s seminal case
on this issue, State v. Linze, 161 Idaho 605, 609, 389 P.3d 150, 154 (2016). In Linze, this Court
held:
The stop remains a reasonable seizure while the officer diligently pursues the
purpose of the stop, to which that reasonable suspicion is related. However, should
the officer abandon the purpose of the stop, the officer no longer has that original
reasonable suspicion supporting his actions. Indeed, when an officer abandons his
or her original purpose, the officer has for all intents and purposes initiated a new
seizure with a new purpose; one which requires its own reasonableness under the
Fourth Amendment. This new seizure cannot piggy-back on the reasonableness of
the original seizure. In other words, unless some new reasonable suspicion or
probable cause arises to justify the seizure’s new purpose, a seized party’s Fourth
Amendment rights are violated when the original purpose of the stop is abandoned
(unless that abandonment falls within some established exception).
Id. (emphasis added).
Linze dealt with whether the time during which the drug detection dog conducted its sweep
of the vehicle was an impermissible extension of the original traffic stop. There can be no question
that this Court’s attention in Linze was on whether the officer abandoned the purpose for which
reasonable suspicion supported the stop in the first place. The majority now prefers to focus on
whether the officer “deviated” from the original purpose of the stop, but I read the facts of
Rodriguez to require a cessation of the reason for the initial stop (in the form of an abandonment)
to trigger the application of its rule. Since an abandonment occurred in Linze, the future fruits of
the officer’s efforts were suppressed as illegal fruits of unconstitutional conduct. Id. The majority
now claims that the proper focus is whether the dog sniff “prolonged” or “added time” to the stop

13
and that whether the officer “abandoned” the stop is not determinative. But this reasoning ignores
the fundamental truth that absent abandonment by an officer, any time that is “added” to a stop is
lawful. A myriad of our “extended stop” cases since Linze support this conclusion – they were
centered precisely on whether the officer abandoned the purpose of the stop. See, e.g., State v.
Warren, ___ Idaho ___, 499 P.3d 423, 427 (2021) (emphasis added) (“Guided by the Supreme
Court’s holding in Rodriguez, we determined Linze’s Fourth Amendment rights had been violated
because the officer who initiated the traffic stop abandoned the traffic stop in order to pursue an
investigation not based on reasonable suspicion.”); State v. Pylican, 167 Idaho 745, 754, 477 P.3d
180, 189 (2020) (emphasis added) (“Rodriguez stands for the proposition that the underlying safety
concerns which justify exit orders do not extend to general criminal investigations that are
undertaken when the purpose of the lawful stop has been abandoned.”).
The majority also claims that “[n]owhere does the majority in Rodriguez use—or apply—
the concept of ‘abandonment’ to reach its rule.” While I agree the word “abandon” does not appear
in the Rodriguez majority opinion, I respectfully disagree that the notion of abandonment was not
applied as the underpinning of the rule which holds:
[T]he tolerable duration of police inquiries in the traffic-stop context is determined
by the seizure’s “mission”—to address the traffic violation that warranted the stop, .
. . and attend to related safety concerns. . . . See also Florida v. Royer, 460 U.S.
491, 500 (1983) (plurality opinion) (“The scope of the detention must be carefully
tailored to its underlying justification.”). . . . Authority for the seizure thus ends
when tasks tied to the traffic infraction are—or reasonably should have been—
completed.
Rodriguez v. United States, 575 U.S. 348, 354 (2015) (most citations omitted). To me, when an
officer forsakes the initial justification for the traffic stop’s “mission,” or moves on from the
reasonable completion of the tasks tied to the stop, the officer has abandoned the initial reason for
the stop. Idaho’s courts’ use of that term to describe this rule is thus more than an errant misuse of
language; it is a precise descriptor of when the inflexible Rodriguez rule is to be applied.
The word “abandon” has many definitions. For example, the term is defined in Merriam-
Webster as “to cease intending or attempting to perform.” 1 It also means “to leave a place, thing,

or person, usually forever.” 2 In other contexts, this Court has explained that “[t]here can be no
abandonment without an intention to abandon.” Union Grain & Elevator Co. v. McCammon Ditch
Co., 41 Idaho 216, 223, 240 P. 443, 445 (1925). In Linze, it was clear the officer abandoned the
traffic mission. The officer left the patrol car and provided back-up to a second officer while the
dog performed the drug-sniff. Linze, 161 Idaho at 607, 389 P.3d at 152. Likewise, the officer in
Rodriguez abandoned the stop; once the officer handed Rodriguez the written warning, the initial
reason for the stop was over and he abandoned that reason by taking further investigative steps.
Rodriguez, 575 U.S. at 352. Thus, the majority’s disregarding abandonment as the crux of these
decisions is to engage in a semantic façade.
This point is underscored further by noting that two of the three justices who today assert
that “[w]hether the officer ‘abandoned’ the traffic stop is not determinative,” certainly considered
it to be so in an earlier dissent:
It is axiomatic that the time to complete the stop was extended by the time it took
for the deputy to order Pylican from her vehicle and escort her to the area near the
front of the deputy's vehicle. During this time, the deputy had abandoned both
purposes of the stop, i.e., the traffic stop and Pylican's presence in the storage
facility. While I recognize that the period of time in which the deputy abandoned
the purposes of the stop was minimal, the standard recognized in both Rodriguez
and Linze is inflexible. Any amount of time in which the purpose of the stop is
abandoned for “[o]n-scene investigation into other crimes” impermissibly extends
the time needed to complete the original purpose of the stop, however otherwise
valid. See Rodriguez, 575 U.S. at 356, 135 S.Ct. 1609.
Pylican, 167 Idaho at 757, 477 P.3d at 192 (Stegner, J. and Brody, J., dissenting) (emphasis added).
Indeed, in both Pylican and Linze, the crucial focus on abandonment was determinative.
Abandonment was referenced again in a recent concurrence to State v. Warren: “When this
purpose was abandoned to investigate Steven's potential violation of a civil protection order and a
criminal no contact order prohibiting him from having contact with Jennifer, officers possessed no
reasonable suspicion specific to Jennifer which allowed them to eventually search both her person
and her belongings.” Warren, ___ Idaho at ___, 499 P.3d at 429 (Stegner, J., concurring).
In 2020, this Court recognized the important distinction between unconstitutionally
prolonging a stop and a permissible extension in State v. Pylican, 167 Idaho 745, 754, 477 P.3d

180, 189 (2020). We focused on the fact that a deputy made a lawful traffic stop, and before the
deputy had checked any of Pylican’s information, a K-9 officer arrived to begin a dog sniff. Id. at
749, 477 P.3d at 189. After the deputy spoke to the K-9 officer—but before the traffic stop was
complete—the deputy ordered Pylican and her passenger out of the vehicle. Id. Critically, the K-
9 officer had reasonable suspicion of criminal activity independent of the reason for the stop when
he ordered Pylican from the vehicle. See id. at 751, 477 P.3d at 186. Before exiting the vehicle,
Pylican began to question the deputy about why she was being asked to exit the vehicle and when
she could use her phone. Id. at 755, 477 P.3d at 190. When Pylican did step out of the vehicle, the
deputy ran her information and resumed discussions with her about the reason for the stop while
the K-9 officer ran the dog around the vehicle. Id. This Court explained Pylican was
distinguishable from both Rodriguez and Linze because the duration of the stop was not prolonged
from the sniff but extended from Pylican questioning the deputy’s command to exit the vehicle.
Id. In addition, we held that the stop was not prolonged by an independent investigation supported
by reasonable suspicion. Id. at 754, 477 P.3d at 189. “Rodriguez…was about the timing of the
officer’s actions,” and not a bar to officers investigating crimes unrelated to a valid traffic stop. Id.
This Court mirrored Pylican in our recent decision in State v. Hale, 168 Idaho 863, 489
P.3d 450 (2021). There, the question presented was whether a delay during a traffic stop to
investigate contradictory information provided by the driver amounted to a violation of Rodriguez.
In holding that such a delay was permissible, we stated:
Our holding does not give law enforcement carte blanche to investigate every piece
of information provided as part of a traffic stop ad infinitum while awaiting an
inbound drug-detecting canine unit. Rather, the lawful duration of a traffic stop is
tethered to “when tasks tied to the traffic infraction are—or reasonably should have
been—completed.”
Id. at 869, 489 P.3d at 456 (quoting Rodriguez, 575 U.S. at 354 (emphasis in original)).
Today, with a broad stroke, the majority reaches a different result than in Pylican based
not on whether Sergeant Hyle impermissibly abandoned the original purpose of the stop—he
certainly didn’t—but whether he added time to the traffic stop by waiting nineteen seconds for
dispatch to respond to his request for a drug dog unit in the middle of the traffic stop. But viewed
in light of Pylican and Hale, neither Linze nor Rodriguez compel the result the majority reaches
here. The facts of both Linze and Rodriguez turned on officers who had completed their missions
and continued the detention to conduct a dog-sniff. Alternatively, here, the initial stop was

16
uncompleted and ongoing when Sergeant Hyle asked for a K9 unit and waited on dispatch. The
sergeant’s conduct was lawful based on Pylican and Hale. The brief nineteen-second delay is
insufficient to establish that the traffic stop was abandoned or that it was unreasonably prolonged
while Sergeant Hyle waited for a response from dispatch. There was no abandonment and thus no
unconstitutional delay.
Additionally, the inflexibility further etched into the Fourth Amendment by the majority
today cannot coexist with the reasonableness that Amendment demands. “[T]he ultimate
touchstone of the Fourth Amendment is ‘reasonableness.’ ” Brigham City v. Stuart, 547 U.S. 398,
403 (2006). The Supreme Court has defined reasonableness “in objective terms by examining the
totality of the circumstances[.]” Ohio v. Robinette, 519 U.S. 33, 39 (1996). This examination also
considers “the traditional protections against unreasonable searches and seizures afforded by the
common law at the time of the framing[.]” Atwater v. Lago Vista, 532 U.S. 318, 326 (2001). When
the common law has not provided a clear answer, Supreme Court precedents have “analyzed a
search or seizure in light of traditional standards of reasonableness by assessing, on the one hand,
the degree to which it intrudes upon an individual’s privacy and, on the other, the degree to which
it is needed for the promotion of legitimate governmental interests.” Virginia v. Moore, 553 U.S.
164, 171 (2008) (internal quotation marks omitted).
“To be reasonable is not to be perfect[.]” Heien v. North Carolina, 574 U.S. 54, 60–61
(2014). Engraining the majority’s inflexible rule deeper into our jurisprudence makes the
possibility all too likely that “a traffic stop made by a rookie could be executed in a reasonable
manner, whereas the same traffic stop made by a knowledgeable veteran officer in precisely the
same circumstances might not, if in fact his knowledge and experience made him capable of
completing the stop faster.” Rodriguez, 575 U.S. at 359 (Kennedy, J., dissenting). The rule the
Court adopts today is unworkable in the real world. I await with interest the future cases we may
see involving a one-second delay because the officer sneezed, or a few seconds of additional time
necessary for an officer to find a pen to write a citation.
The dog sniff at Karst’s vehicle did not extend the stop—the response from dispatch did.
Had dispatch responded immediately, there would not have been a nineteen-second pause. By
inquiring into the duration of the stop to determine the precise moment a pause constitutes a
prolonging, this rule will penalize officers for factors outside their control. At a separate traffic
stop, with a different dispatcher, an officer could conduct the same dog sniff and the majority’s
17
rule would uphold the results. This is not the bright line rule the majority contends, but an arbitrary
one that could have unpredictable consequences; it rewards expedience and abandons
reasonableness.
The first question to ask in any of these cases is whether the officer abandoned the mission
or purpose for the initial detention. If not, then the officer’s conduct is not a per se violation of the
Fourth Amendment. From there, the conclusion I would reach is that a stop that is briefly
lengthened by a short pause is permissible so long as the reason for the stop is not abandoned by
conduct that measurably extends the stop. See United States v. Everett, 601 F.3d 484, 491 (6th Cir.
2010) (explaining that a “measurable” delay is one that is “significant,” i.e., that unreasonably
prolongs the stop). This approach is one many other jurisdictions have also taken when faced with
reconciling Rodriguez. See, e.g., State v. Cassady, 56 N.E.3d 662, 668 (Ind. App. 2016) (holding
that a deputy did not violate a motorist’s Fourth Amendment rights when a dog-sniff was
performed while a deputy was waiting on a response from dispatch for a license check); State v.
Sosa, 427 P.3d 448, 451 (Utah Ct. App. 2018) (distinguishing a request for a dog sniff and the
resulting alert that occurred during the traffic stop from Rodriguez); State v. Allen, 779 S.E.2d 248
(Ga. 2015) (holding that a dog sniff conducted while the officer awaited the return of a computer
records check does not prolong the stop). Following these authorities, and for the reasons stated
above, I would affirm the district court.
