Justice Beth Baker delivered the Opinion of the Court.

¶1 Quincy Smith appeals the Twenty-First Judicial District Court’s order denying his 

motion to suppress evidence obtained when law enforcement officers entered his private 

property without a warrant. We address the following issues on appeal:

1. Did Smith have a reasonable expectation of privacy in the driveway of his 

residence when he told a sheriff’s deputy attempting to effectuate a traffic stop that 

he was trespassing and needed a warrant?

2. Did exigent circumstances exist to allow the sheriff’s deputy to conduct a 

warrantless investigation on the property?

We hold that the deputy sheriff properly entered the driveway when he already had initiated 

a traffic stop but exceeded his authority after Smith asked him to leave. We therefore 

reverse. 

FACTUAL AND PROCEDURAL BACKGROUND

¶2 On May 15, 2019, Smith and his friend Jacques Hennequin were driving eastbound 

on Hidden Valley Road in Ravalli County to Hennequin’s house, where Smith resided. 

Ravalli County Sheriff’s Deputy Nicholas Monaco, driving westbound on Hidden Valley 

Road, observed Smith’s vehicle traveling at approximately 57 miles per hour—17 miles 

per hour over the speed limit. Deputy Monaco activated his lights, turned around, and 

pursued Smith. Deputy Monaco’s dash camera footage shows that Smith’s vehicle was 

visible for approximately one second before it rounded an “S” shaped curve in the road. 

Approximately twenty-one seconds after Deputy Monaco activated his lights, Smith turned 

down a 350-foot residential driveway and parked next to the garage. 
3

¶3 The Hennequins’ house is located on five acres. It has a perimeter fence and an 

interior fence around the house and yard. Although both fences have gates, neither gate 

was closed that night, and there was no gate at the entrance to the driveway. The residence 

is surrounded by trees and foliage, and the physical nature of the property secludes it from 

the road and neighboring properties. The property did not have any “No Trespassing” signs 

posted. 

¶4 Shortly after Smith parked his vehicle, Deputy Monaco pulled into the driveway 

and approached Smith and Hennequin. He advised them that Smith had been speeding. 

Smith and Hennequin both immediately informed Deputy Monaco that he was on private 

property and requested that he return with a warrant:

SMITH: Sir we were just down the way –

MONACO: I understand that.

SMITH: – just pulling in here. Thirty seconds away. We just –

MONACO: I understand that. Are you the passenger, sir?

HENNEQUIN: Yeah.

MONACO: Ok. Do you have ID on you?

HENNEQUIN: Yeah

MONACO: Ok.

HENNEQUIN: I mean, do you need it? I mean, this is my house.

. . .

SMITH: You’re on private property.

MONACO: I understand that. 

SMITH: You’re on private property. 
4

. . .

SMITH: I’m pretty sure you can’t pull in like this.

HENNEQUIN: Yeah, you really can’t, man.

MONACO: Ok, are you going to provide me your license, registration, and 

insurance?

SMITH: At this point right now –

HENNEQUIN: You know what? No, we’re not—

SMITH: At this point—

HENNEQUIN: We’re not. You can go get a warrant, man.

¶5 Deputy Monaco did not leave the property or obtain a warrant. Instead, he requested 

back-up and continued his investigation by asking Smith for his driver’s license and 

registration. The stop ripened into a driving under the influence (DUI) investigation after 

Deputy Monaco observed that Smith smelled of alcohol and inquired if he had been 

drinking. Smith admitted that he had a few drinks at a local bar. Sergeant Guisinger, 

Deputy Monaco’s back-up, arrived and the confrontation continued. Sergeant Guisinger 

tased Smith after he refused to comply with the officers’ directives, and Deputy Monaco 

arrested him. 

¶6 The State charged Smith with speeding, in violation of § 61-8-309, MCA, 

obstructing a peace officer in violation of § 45-7-302, MCA, DUI in violation of 

§ 61-8-401, MCA, and resisting arrest in violation of § 45-7-301, MCA, all misdemeanors. 

Smith moved the Justice Court to suppress all evidence obtained from Smith’s contact with 

the officers, arguing that he had a reasonable expectation of privacy in the driveway of the 
5

residence and that Deputy Monaco’s warrantless entry and refusal to leave the property 

violated his constitutional rights. The Justice Court denied the motion without a hearing. 

Following a bench trial, the court found Smith guilty of all charges. 

¶7 Smith appealed to the Twenty-First Judicial District Court. At a hearing on the 

motion to suppress, Hennequin and his wife Carli testified to the privacy of their home, 

explaining that the secluded nature of the property was their biggest consideration in

purchasing it. Deputy Monaco testified to the circumstances of the stop, including his 

pursuit, his interaction with Smith and Hennequin, and his belief that a warrant was not 

necessary to enter the driveway of the residence. 

¶8 The District Court denied Smith’s motion to suppress, concluding that Smith did 

not have a reasonable expectation of privacy. The court explained that there was 

“[n]o evidence indicat[ing] that either defendant or Hennequin required prior permission 

before entering the property” and that the property must have more than “landscaping and 

field fencing” to “confer an expectation of privacy equivalent to that conferred upon a 

residence.” Because the court found that Smith had no reasonable expectation of privacy 

in the driveway, it did not address whether exigent circumstances justified

Deputy Monaco’s warrantless entry. Smith pleaded guilty to a misdemeanor DUI, 

reserving his right to appeal the District Court’s denial of his motion to suppress. 

STANDARDS OF REVIEW

¶9 We review the denial of a motion to suppress to determine whether the lower court’s 

findings of fact were clearly erroneous; we review de novo the court’s interpretation and 
6

application of the governing law. State v. Staker, 2021 MT 151, ¶ 7, 404 Mont. 307, 

489 P.3d 489 (citations omitted). A finding of fact is clearly erroneous if it is not supported 

by substantial credible evidence, if the lower court has misapprehended the effect of the 

evidence, or if our review of the record creates a firm conviction that a mistake was made. 

State v. Hoang Vinh Pham, 2021 MT 270, ¶ 11, 406 Mont. 109, 497 P.3d 217 (citing 

City of Missoula v. Metz, 2019 MT 264, ¶ 12, 397 Mont. 467, 451 P.3d 530). 

DISCUSSION

¶10 1. Did Smith have a reasonable expectation of privacy in the driveway of his 

residence when he told a sheriff’s deputy attempting to effectuate a traffic stop that he was 

trespassing and needed a warrant?

¶11 The Fourth Amendment to the United States Constitution and Article II, Section 11,

of the Montana Constitution prohibit unreasonable searches and seizures. “The 

fundamental purpose of the Fourth Amendment and Article II, Section 11 is to protect the 

privacy and security of individuals from unreasonable government intrusion or 

interference.” Hoang Vinh Pham, ¶ 13 (citation and internal quotation omitted). 

¶12 “States are free to grant citizens greater protections based on state constitutional 

provisions than the United States Supreme Court divines from the United States 

Constitution.” State v. Bullock, 272 Mont. 361, 383-84, 901 P.2d 61, 75 (1995) (citations 

omitted). Montana has done so through Article II, Section 10, of the Montana Constitution, 

which provides that the right of individual privacy “shall not be infringed without the

showing of a compelling state interest.” Because of that heightened privacy right, the 
7

Montana Constitution affords broader protection against searches and seizures than does 

the Fourth Amendment alone. Bullock, 272 Mont. at 383, 901 P.2d at 75. 

¶13 Smith argues that he had a reasonable expectation of privacy in the driveway of his 

residence. Because the driveway is within the curtilage of the home or, alternatively, 

because the nature of the property satisfies Bullock, Smith asserts that Deputy Monaco’s 

warrantless entry onto the property and refusal to leave over Smith’s repeated requests 

violated his right to be free from unreasonable searches. 

¶14 The State responds that Smith did not have an expectation of privacy that society 

would recognize as reasonable. Smith’s property, the State asserts, is distinguishable from 

that in Bullock, and Smith’s failure to stop gave implied consent for Deputy Monaco to 

enter the property.

¶15 Montana’s heightened right to privacy cannot be construed to offer less protection 

than what the Fourth Amendment guarantees. See Bullock, 272 Mont. at 383, 

901 P.2d at 75. Under the Fourth Amendment, a person has a reasonable expectation of 

privacy within the curtilage of his or her home—the area immediately surrounding a 

dwelling—but not beyond that. Florida v. Jardines, 569 U.S. 1, 6-7, 133 S. Ct. 1409, 1414-

15 (2013). The United States Supreme Court has found a front porch, the area “outside the 

front window,” and a garage all within the curtilage of the home. Jardines, 569 U.S. at 6-

7, 133 S. Ct. at 1415; see Lange v. California, 594 U.S. __, __, 141 S. Ct. 2011, 2018

(2021). In Collins v. Virginia, the Court held that a driveway was within the curtilage of 

the home when it ran alongside the front yard, the top portion of the driveway sat behind 
8

the front perimeter of the house, and the top of the driveway was enclosed on two sides by 

brick wall and by the house on a third side. 584 U.S. __, __, 138 S. Ct. 1663, 1670-71, 

(2018). The house was accessible from the driveway through a side door. Collins, 584 

U.S. at __, 138 S. Ct. at 1670-71. The Court held that the driveway was “properly 

considered curtilage,” explaining that the driveway was an extension of the home, the area 

searched was “adjacent to the home,” and “activity of home life extend[ed]” onto the 

driveway. Collins, 584 U.S. at __, 138 S. Ct. at 1671 (internal quotations omitted). 

¶16 We find it unnecessary to determine whether the driveway was within the curtilage

of Smith’s dwelling under the Collins framework. If it was not and Smith did not have a

reasonable expectation of privacy under the Fourth Amendment, our review is not cabined 

by a Fourth Amendment analysis. If it was within the curtilage, we would reach the same 

outcome given our analysis under the Montana Constitution. 

¶17 We turn to that analysis. In Bullock, we rejected the distinction between curtilage 

and open fields drawn under the Fourth Amendment, refusing as “repugnant to our State’s 

explicit recognition of privacy as a fundamental right” a categorical rule that an individual 

does not have a right to privacy in open fields. Bullock, 272 Mont. at 384, 901 P.2d at 75. 

Under Bullock and its progeny, to determine whether an unlawful government search has 

occurred, we look to “(1) whether [an individual has] an actual expectation of privacy . . .; 

(2) whether society is willing to recognize that expectation as objectively reasonable; and 

(3) the nature of the [S]tate’s intrusion” to determine whether an unlawful government
9

search has occurred. Estate of Frazier v. Miller, 2021 MT 85, ¶ 25, 404 Mont. 1, 

484 P.3d 912 (quoting State v. Smith, 2004 MT 234, ¶ 10, 322 Mont. 466, 97 P.3d 567). 

¶18 An individual has an actual expectation of privacy beyond the curtilage of his or her

home when the individual has evidenced the expectation “by fencing, [by posting] 

‘No Trespassing’ or similar signs, or ‘by some other means [which] indicates unmistakably 

that entry is not permitted.’” Bullock, 272 Mont. at 384, 901 P.2d at 75-76 (citing 

New York v. Scott, 593 N.E.2d 1328, 1338 (N.Y. 1992)). We held in Bullock that the 

defendant had an actual expectation of privacy beyond the curtilage of his cabin because 

the defendant had gone to great lengths to protect the privacy of his cabin by moving it

back from the road, erecting a fence and gate between his property and the road, and posting 

“No Trespassing” signs. Bullock, 272 Mont. at 385, 901 P.2d at 76. 

¶19 Smith argues that he had an actual expectation of privacy on the property under

Bullock because of the length of the driveway, the perimeter and interior fencing 

surrounding the property, and the naturally secluded nature of the property. Smith points 

to the Hennequins’ testimony that the privacy of the home was their 

“biggest consideration” in purchasing the property to evidence their subjective expectation 

of privacy. True, the property is secluded, but as the District Court recognized, neither the 

Hennequins, as owners of the property, nor Smith, as a resident, “took measures” to 

evidence their expectation of privacy or communicated that “entry [was] not permitted.”

See State v. Hubbel, 286 Mont. 200, 209, 951 P.2d 971, 976 (1997). Both the perimeter 

and interior fences had gates, but neither gate was closed, and nothing indicated that entry 
10

to the driveway was not permitted. Neither the Hennequins nor Smith had posted

“No Trespassing” signs on either fence. Though foliage and the property’s natural features

shielded the residence from view, neither the Hennequins nor Smith took any affirmative 

steps to protect the privacy of the property or to “indicat[e] unmistakably” that no entry 

was permitted. See Bullock, 272 Mont. at 381, 901 P.2d at 74. This is contrary to

Bullock, where the landowner moved his cabin further from the road, erected a fence 

between the road and the property, and posted “No Trespassing” signs for privacy. 

272 Mont. at 384-85, 901 P.2d at 76. No similar measures gave warning to Deputy Monaco 

that he should not enter the property to complete the traffic stop he had initiated on a public 

road. 

¶20 The dynamic changed, however, once Deputy Monaco confirmed that Smith had 

just arrived at his own home. Smith told the Deputy that he was trespassing on private 

property. Smith communicated to Deputy Monaco in clear terms that “entry [was] not 

permitted,” see Hubbel, 286 Mont. at 209, 951 P.2d at 976, telling him that he needed to 

leave the property if he did not have a warrant. This clear invocation of privacy rights 

demonstrated to Deputy Monaco that Smith had an actual expectation of privacy on the 

property. See Bullock, 272 Mont. at 384, 901 P.2d at 76; Hubbel, 286 Mont. at 209-10, 

951 P.2d at 976. 

¶21 Whether an individual’s privacy expectation is reasonable depends upon several 

overlapping factors, including “the place of the investigation, the control exercised by the 

person over the property being investigated, and the extent to which the person took 
11

measures to shield the property from public view, to communicate entry is not permitted, 

or to otherwise protect his property from intrusion.” Hubbel, 286 Mont. at 209, 

951 P.2d at 976. See also State v. Dunn, 2007 MT 296, ¶ 13, 340 Mont. 31, 172 P.3d 110. 

Society recognizes an actual expectation of privacy as reasonable when a resident makes 

that expectation “unmistakably” apparent through “No Trespassing” signs, gates, or by 

communicating that entry is not allowed. Bullock, 272 Mont. at 384, 901 P.2d at 76; 

Hubbel, 286 Mont. at 209-10, 951 P.2d at 976. We held in Bullock that the defendant’s 

expectation of privacy was reasonable because he took numerous affirmative steps to 

communicate his actual expectation of privacy by moving his cabin back from the road to 

shield it from view, posting “No Trespassing” signs, and erecting a fence and gate.

272 Mont. at 384, 901 P.2d at 75-76. Conversely, in Hubbel, we held the defendant had 

no reasonable expectation of privacy in the property leading up to his front door when the 

property abutted a heavily trafficked highway and the defendant took no steps to shield the 

property from public view or to prevent passersby from approaching the house. 

286 Mont. at 210, 951 P.2d at 977. Unlike in Bullock, neither Smith nor the Hennequins

took affirmative action to keep people from coming up the driveway. Once Smith told

Deputy Monaco that he was trespassing and told him to obtain a warrant, however, that 

communication was unmistakable. The privacy of the home is at the “very core” of 

constitutional search and seizure protections. Collins, 584 U.S. at ___, 138 S. Ct. at 1670.

Society would recognize Smith’s actual expectation of privacy as reasonable when he 

refused to answer a law enforcement officer’s questions outside his own home absent a 
12

warrant. See Bullock, 272 Mont. at 384, 901 P.2d at 76; Hubbel, 286 Mont. at 209-10, 

951 P.2d at 976. 

¶22 Finally, we look to the nature of the State’s intrusion to determine whether it 

infringed upon Smith’s reasonable expectation of privacy. Estate of Frazier, ¶ 19. The 

State does not dispute that Deputy Monaco conducted a search but argues that the nature 

of the intrusion was minimal given the circumstances of the stop. We agree that 

Deputy Monaco acted appropriately in pursuing Smith’s vehicle into the driveway on his 

reasonable belief that Smith was aware that he was being stopped. Unlike in Bullock, 

where law enforcement officers entered Bullock’s property to conduct an investigation, 

Deputy Monaco entered the property to effectuate a traffic stop he initiated on a public 

road. 272 Mont. at 384-85, 901 P.2d at 76. Deputy Monaco’s initial questions to ascertain 

who lived at the home and whether Smith was the driver were minimally intrusive and 

necessary to inform him whether he should continue or seek a warrant for further 

investigation. See City of Missoula v. Kroschel, 2018 MT 142, ¶¶ 14-15, 391 Mont. 457, 

419 P.3d 1208 (incident to a lawful stop, law enforcement officers may request a person’s 

name, current address, and an explanation of the person’s conduct). See also State v. Boyer, 

2002 MT 33, ¶¶ 25, 33, 308 Mont. 276, 42 P.3d 771 (a game warden’s entry onto the 

transom of a boat to briefly question the angler and inspect his fish was a minimal 

intrusion). After those preliminary questions, Smith explicitly invoked his right to privacy. 

At that point, the State’s intrusion became more extensive when Deputy Monaco began to 

question Smith about his drinking and expanded the investigation to one for DUI. To the 
13

extent that Smith brought the encounter onto the property and implicitly consented to 

Deputy Monaco’s presence, that consent was explicitly revoked once Smith asserted that 

Deputy Monaco was trespassing and requested that he obtain a warrant. At that point, the 

Deputy’s continued questioning subjected Smith to a search requiring either a warrant or 

an exception to the warrant requirement.

¶23 2. Did exigent circumstances exist to allow the sheriff’s deputy to conduct a 

warrantless investigation on the property?

¶24 When an individual has a reasonable expectation of privacy, a search conducted 

without a warrant is presumptively unreasonable unless it meets one of few delineated 

exceptions. Bullock, 272 Mont. at 374, 901 P.2d at 70. Exigent circumstances are one 

exception to the warrant requirement. State v. Saale, 2009 MT 95, ¶ 10, 350 Mont. 64, 

204 P.3d 1220 (citing State v. Wakeford, 1998 MT 16, ¶ 22, 287 Mont. 220, 953 P.2d 1065). 

An exigent circumstance is one “that would cause a reasonable person to believe that entry 

(or other relevant prompt action) was necessary to prevent physical harm to the officers or 

other persons, the destruction of relevant evidence, the escape of the suspect, or some other 

consequence improperly frustrating legitimate law enforcement efforts.” Wakeford, ¶ 24. 

The State bears a heavy burden of showing that an exigent circumstance exists. Saale, ¶ 10 

(citing Wakeford, ¶ 24). 

¶25 The State asserts that the Justice Court and District Court were correct in denying 

Smith’s motions to suppress because exigent circumstances justified Deputy Monaco’s 

warrantless entry. The State first argues that Smith’s failure to stop after Deputy Monaco 

initiated contact constituted hot pursuit. Law enforcement in “hot pursuit” of a fleeing 
14

felon may make a warrantless entry “if the exigencies of the situation make that course 

imperative.” State v. Sorenson, 180 Mont. 269, 273, 590 P.2d 136, 139 (1979) (citations 

and quotations omitted). See also State v. Dow, 256 Mont. 126, 130, 844 P.2d 780, 783

(1992). We held in Sorenson that law enforcement did not have exigent circumstances to 

enter the defendant’s home in pursuit of a teenager who had threatened a school principal 

while house-sitting for the defendant. Sorenson, 180 Mont. at 274-75, 590 P.2d at 139-40. 

We concluded that officers were not in hot pursuit of the teenager because the principal’s 

safety was secured and there was no immediate threat of harm. Sorenson, 180 Mont. at 275, 

590 P.2d at 140. We held that hot pursuit justifies a warrantless entry only if “a felony has 

been committed and the suspect is fleeing.” Sorenson, 180 Mont. at 274, 590 P.2d at 139. 

In its brief on appeal, the State urges us to expand our holding in Sorenson to include 

fleeing misdemeanants, citing a split in jurisdictions on the issue. 

¶26 Contemporaneous with the State’s filing of its brief in this appeal, the United States 

Supreme Court addressed the issue of fleeing misdemeanants. Lange v. California, 

594 U.S. __, 141 S. Ct. 2011 (2021). There, in a situation much like Smith’s, an officer 

tried to initiate a stop approximately one hundred feet from Lange’s home. 

Lange, 594 U.S. at __, 141 S. Ct. at 2016. Instead of stopping, Lange pulled into his 

driveway and parked in his attached garage. Lange, 594 U.S. at __, 141 S. Ct. at 2016. 

The officer followed Lange into the garage, observed signs of intoxication, ran field 

sobriety tests, and arrested Lange for a misdemeanor DUI. Lange, 594 U.S. at __, 

141 S. Ct. at 2016. Amicus appointed to represent California’s interests argued that the 
15

Supreme Court should adopt a categorical rule that exigency exists in every case of 

misdemeanor pursuit. Lange, 594 U.S. at __, 141 S. Ct. at 2018. Rejecting such a 

broad-sweeping rule, the Court observed:

The flight of a suspected misdemeanant does not always justify a warrantless 

entry into a home. An officer must consider all circumstances in a pursuit 

case to determine whether there is a law enforcement emergency. On many 

occasions, the officer will have good reason to enter [without a warrant]—to 

prevent imminent harms of violence, destruction of evidence, or escape from 

the home. But when the officer has time to get a warrant, he must do so—

even though the misdemeanant fled.

Lange, 594 U.S. at __, 141 S. Ct. at 2024.

¶27 A review of the record shows that the State did not demonstrate circumstances 

beyond Smith’s failure to stop that created a “good reason” for Deputy Monaco to remain 

on the property without a warrant. Lange, 594 U.S. at __, 141 S. Ct. at 2024. It did not 

present evidence of any risk that Smith would escape from the home, harm the officer, or 

harm another person, or demonstrate that Deputy Monaco was unable to obtain a warrant 

or take steps to prevent Smith from escaping while he did so. 

¶28 The State contends, though, that obtaining a warrant would have “hindered” 

Deputy Monaco’s investigation and would have allowed Smith to “avoid liability” for the 

DUI because he could have claimed he consumed alcohol after arriving home. This 

argument fails to acknowledge that Deputy Monaco had seen no sign of impaired driving 

and did not have particularized suspicion that Smith was under the influence until over 

seven minutes into the stop when he observed that Smith smelled of alcohol. By this point, 

Smith had asserted his right to privacy and requested that Deputy Monaco obtain a warrant. 
16

Deputy Monaco had stopped him only for speeding. “[T]he [exigent circumstances] 

exception is ‘case-specific.’” Lange, 594 U.S. at __, 141 S. Ct. at 2018 (quoting 

Riley v. California, 573 U.S. 373, 388, 134 S. Ct. 2473, 2486 (2014)). The State did not 

demonstrate that, at the time Smith asserted his right to privacy, Deputy Monaco had 

exigent circumstances to meet the warrant exception. We conclude on the undisputed facts 

of the record that Smith’s failure to stop for a minor traffic violation did not create an 

exigency allowing Deputy Monaco to conduct a warrantless investigation after Smith 

invoked his right to privacy.

CONCLUSION

¶29 Smith had a reasonable expectation of privacy in the driveway of his residence once

he told Deputy Monaco he was trespassing and needed to return with a warrant. The State 

did not prove exigent circumstances permitting a warrantless search. We reverse the 

District Court’s judgment and remand with instruction to enter an order suppressing all 

evidence obtained by the officers after they were told to leave Smith’s residence.

Justice Jim Rice, specially concurring. 

¶30 I generally concur with the Court’s Opinion but write separately to expand upon the 

unique facts here and emphasize that, in my view, the Court’s conclusion is a narrow one 

necessarily required by the U.S. Supreme Court’s decision in Lange, but which should not 

unduly constrain law enforcement. 

¶31 I agree with the Court’s conclusion that Deputy Monaco (Monaco) was permitted 

to follow Smith up the driveway to complete the stop. In my view, this was permissible

not only because the incident began on a public roadway, but also because at that point 

Monaco did not have any indication that the driveway actually led to a residence owned by 

Smith, the suspect vehicle’s driver. The facts here are in contrast with Bullock and Saale, 

where law enforcement approached the defendants’ residences specifically because they 

already believed the defendants lived there. While I agree Smith had a privacy interest in 

Hennequin’s house as a resident there, Monaco did not know any of that at the time Smith’s 

car turned up the driveway. A person’s privacy interests do not extend to any private 

property. See Lange, 594 U.S. at ___, 141 S. Ct. at 2018 (“Freedom in one’s own dwelling

is the archetype of the privacy protection secured by the Fourth Amendment”) (citing 

Payton v. New York, 445 U.S. 573, 585, 587, 100 S. Ct. 1371, 1380 (1980)) (internal 

quotation marks omitted) (emphasis added). Indeed, the rare circumstances that had 

developed at that point—the activation of the abundantly clear lights of Monaco’s cruiser 
18

during darkness,

1

followed by Smith’s failure to stop, his immediate exit from the road, 

and entry upon a dirt road—raised ample reason to doubt that Smith was approaching a 

residence as opposed to evading the officer, or that the dirt road led to a residence that was 

his. Monaco was justified in following Smith’s vehicle up the driveway because he could 

not have known Smith was heading to his residence rather than simply trying to flee or 

hide up a random road. 

¶32 Once up the driveway, Monaco found Smith and Hennequin outside the vehicle. 

They had not entered the residence nor, based on the dash-camera video, made any attempt 

to. Instead, they both asserted that they were on private property and Monaco needed to 

leave and obtain a warrant. In my view, this initial assertion of rights was not sufficient by 

itself to put Monaco on sufficient notice that the house was indeed Smith’s residence. In 

Lange, Defendant Lange drove into his garage after a stop was initiated on a public road, 

and the pursuing officer followed him into his garage. Lange, 594 U.S. at ___, 141 S. Ct. 

at 2016. By physically entering his garage, Lange took an affirmative act indicating he 

possessed an ownership or leasehold interest in the building sufficient to put the pursuing 

officer on notice that Lange was in a constitutionally protected space. Such affirmative 

action is necessary in cases such as this, where a suspect has not actually entered the 

residence, to avoid situations in which suspects simply flee to private property and 

fraudulently assert a privacy interest to evade law enforcement—a not unprecedented

factual circumstance. This affirmative action need not be much, but enough to reasonably 

put law enforcement on notice that the suspect indeed resides at the location. Driving into 

a garage, as in Lange, is one such action, but a suspect could, by way of example, also use 

a remote garage door opener to open the garage, actually enter the residence, or have 

someone inside the residence vouch for his residence there. The latter is, in essence, what 

happened here. After an initial reluctance, Hennequin and Smith both produced 

identification to Monaco. Hennequin’s identification proved that he did indeed reside 

there, and by his statements Hennequin backed up Smith’s assertion of his constitutional 

rights. At that point, after the assertion of the privacy right, further warrantless 

investigation by Monaco was improper. 

¶33 However, while Lange prohibits Monaco from further investigating Smith for DUI 

or arresting him for a misdemeanor without a warrant, there remains the matter for which 

Monaco was properly on the property—to complete a stop for the misdemeanor offense of 

speeding. Monaco had properly requested and obtained all of the information necessary to 

issue a Notice to Appear for the speeding violation. In that regard, Monaco had dashcamera footage capturing the incident and radar confirmation showing that Smith was 

speeding, heard Smith voluntarily admitting to that fact, learned Smith’s status as the 

vehicle’s driver, and had properly obtained his identification information. See § 61-8-

309(6), MCA (speeding violation); § 61-8-703, MCA (authorizing warrantless arrest in 

speeding cases where radar establishes the driver was speeding); and § 46-6-310(1), MCA 

(“Whenever a peace officer is authorized to arrest a person without a warrant, the officer 
20

may instead issue the person a notice to appear.”). Monaco could have then completed his 

lawful stop by issuing Smith a Notice to Appear, for which he would have had a short time 

as necessary to continue interacting with Smith for that purpose. Issuance of a Notice to 

Appear is, by its nature, not a seizure because it is issued in lieu of arrest; nor can it be

considered a “search.” See § 46-6-310(1), MCA; State v. Elison, 2000 MT 288, ¶ 48, 302 

Mont. 228, 14 P.3d 456 (defining a “search” as “the use of some means of gathering 

evidence which infringes upon a person’s reasonable expectation of privacy”). If Monaco, 

therefore, detected the odor of alcohol on Smith’s breath as he served the Notice to Appear, 

he would have detected that odor while in a place he had a lawful right to be. Because DUI 

is a misdemeanor, under Lange, Monaco was then required, after issuance of the Notice to 

Appear, to retreat from the property and obtain a warrant in order to conduct a DUI 

investigation. But he would not have had to retreat far, only back to the public road, where 

upon sufficient information to establish probable cause a search warrant could have been 

obtained, which the record indicates was eventually done telephonically. 

¶34 Reduced to its core, the State’s argument is that this is not the most expedient way 

to conduct an investigation. For better or worse, it would appear that Lange’s holding gives 

little consideration to investigative expediency. Be that as it may, it is important to keep 

in mind that Lange’s holding at bottom prohibits only a categorical rule that would permit

warrantless entry into a residence to pursue a suspect fleeing a misdemeanor. Lange, 594 

U.S. at ___, 141 S. Ct. at 2024-25. The Supreme Court was clear that if exigent 

circumstances are present—“prevent[ion of] imminent harms of violence, destruction of 
21

evidence, or escape from the home”—warrantless entry is permissible. Lange, 594 U.S. at 

___, 141 S. Ct. at 2024. If a pursuing officer reasonably believes such exigent 

circumstances are present, he may continue the pursuit or investigation; if there are no 

exigent circumstances regarding a misdemeanor, then the officer must obtain a warrant to 

continue the investigation. And, of course, a law enforcement officer may continue the hot 

pursuit of a person fleeing from a suspected felony. Sorenson, 180 Mont. at 274, 590 P.2d 

at 139. Here, there was no pursuit of a suspected felon, and no exigent circumstances

established that would permit a warrantless investigation for an offense beyond the proper 

stop made for speeding.
