Justice LaVECCHIA
delivered the opinion of the Court.
We granted certification in this matter to address the application of the United States Supreme Court’s decision in
Missouri v. McNeely,
— U.S.-, 133
S.Ct.
1552, 185 L.Ed.2d 696 (2013), to a case involving a blood draw, for purposes of determining blood alcohol content (BAC), that took place before the
McNeely
decision was issued.
Police arrested defendant, Timothy Adkins, on suspicion of drunk driving after his single-vehicle car crash caused injuries to his passengers and he failed field sobriety tests. The police obtained defendant’s BAC test results from a sample, drawn by hospital personnel at police direction, without the police first having secured a warrant or defendant’s prior written consent.
Following issuance of the United States Supreme Court’s decision in
McNeely, supra,
which held that “in drunk-driving investigations, the natural dissipation of alcohol in the bloodstream does not constitute an exigency in every case sufficient to justify conducting a blood test without a warrant,” —
U.S.
at-, 133
S.Ct.
at 1568, 0185 L.Ed.2d at 715, defendant sought suppression of his BAC results. After a hearing in which only defendant testi
fied, the court applied
McNeely
and excluded defendant’s blood test results. On appeal, the Appellate Division reversed, declining to apply the exclusionary rule when officers relied on
pre-McNeely
New Jersey case law that had permitted warrantless blood draws based on the exigency inherent in the human body’s natural dissipation of alcohol.
Consistent with our decision in
State v. Wessells,
209
N.J.
395, 37 A.3d 1122 (2012), we conclude that McNeely’s pronouncement on the Fourth Amendment’s requirements must apply retroactively to cases that were in the pipeline when
McNeely
was issued. We are constrained to adhere to the
McNeely
Court’s totality-of-the-circumstances approach notwithstanding that our case law, like that of many sister states, had provided de facto, if not de jure, support for law enforcement to believe that alcohol dissipation in and of itself supported a finding of exigency for a warrant-less search of bodily fluids in suspected driving-under-the-influence cases.
Because
McNeely
must apply retroactively to all cases, federal or state, pending on direct review at the time of that decision, we must reverse the Appellate Division judgment. However, we remand to allow the State and defendant the opportunity to represent their respective positions on exigency in a hearing on defendant’s motion to suppress the admissibility of the blood test results. We further hold that, in that hearing, potential dissipation of the evidence may be given substantial weight as a factor to be considered in the totality of the circumstances. In reexamining this matter, in which law enforcement may have relied on prior guidance from our Court that did not identify an obligation to evaluate whether a warrant could be obtained, we direct the reviewing court to focus on the objective exigency of the circumstances faced by the officers.
I.
In the early morning hours of December 16, 2010, defendant was involved in a single-car accident that resulted in injuries to
defendant’s two passengers. Based on his performance on a series of field sobriety tests conducted at the scene of the accident, defendant was arrested on suspicion of Driving While Intoxicated (DWI) at approximately 2:27 a.m. Defendant was transported to the West Deptford Police Department and was advised of his
Miranda
rights; he invoked his right to counsel. We understand from this record that although Alcotest equipment was present, no breathalyzer test was administered at headquarters. The record is not clear as to why that is so.
What we do know is that police personnel conveyed him to Underwood Memorial Hospital so that a blood sample could be obtained. At police request, hospital staff drew defendant’s blood at 4:16 a.m. The record does not reveal any objection by defendant to the invasive procedure. The requesting police officer, a hospital nurse, and defendant each signed the Certificate of Request to Withdraw a Specimen, but defendant’s signature was affixed two minutes after the blood was drawn.
Defendant was issued summonses for DWI,
N.J.S.A
39:4-50; careless driving,
N.J.S.A
39:4-97; and possession of an open container in a motor vehicle,
N.J.S.A.
39:4-51a. On August 3, 2011, a grand jury also charged defendant with fourth-degree assault by auto,
N.J.S.A
2C:12-1(c)(2), for recklessly operating a motor vehicle while under the influence of alcohol and causing bodily injury.
On April 17, 2013, the United States Supreme Court issued its opinion in
McNeely, supra,
which held that the natural metabolism of alcohol in an individual’s bloodstream does not constitute a per se exigency under a Fourth Amendment search and seizure analysis. —
U.S.
at-, 133
S.Ct.
at 1568, 185 L.Ed.2d at 715. In light of
McNeely,
on April 22,2013, defendant filed the pre-trial
motion to suppress the blood test results that is at the center of this appeal.
Following a hearing at which only defendant testified, the court granted defendant’s motion, finding that the police did not demonstrate exigent circumstances before securing a sample of defendant’s blood without a warrant.
The State appealed, and the Appellate Division reversed.
State v. Adkins,
433
N.J.Super.
479, 81 A.3d 680 (App.Div.2013). The panel explained that, prior to
McNeely,
New Jersey courts, including this Court, had cited the United States Supreme Court’s prior decision in
Schmerber v. California,
384
U.S.
757, 86
S.Ct.
1826, 16 L.Ed.2d 908 (1966), as support for the warrantless taking of blood samples from suspected intoxicated drivers, so long as the search was supported by probable cause and the sample was obtained in a medically reasonable manner.
Id.
at 482-83, 81 A.3d 680. The panel reasoned therefore that
McNeely
had worked a dramatic shift in this State’s Fourth Amendment jurisprudence and created a new rule of criminal procedure.
Id.
at 484, 81 A.3d 680. The Appellate Division acknowledged that
McNeely
ordinarily would be given “pipeline retroactivity” and would be applied retroactively to all cases, federal or state, pending on direct review.
Ibid.
However, citing
Davis v. United States,
-
U.S.
-,-, 131
S.Ct.
2419, 2434, 180 L.Ed.2d 285, 302 (2011), the panel noted that federal law generally does not apply the exclusionary rule when police conduct a search in good faith reliance on previously binding precedent.
Id.
at 484-85, 81 A.3d 680. Concluding that defendant’s blood sample would not be suppressed under federal law, the panel determined that
the real issue here is whether, given the federal retroactivity requirement, we should, as the State argues, apply an approach analogous to that set forth in
Davis,
or whether, as defendant argues, the result here is dictated by
State v. Novembrino,
105
N.J.
95, 157-59 [519 A.2d 820] (1987), which rejected a “good faith” exception to the application of the exclusionary rule.
[Id.
at 488, 81 A.3d 680.]
Ultimately, the panel held that the exclusionary rule should not be applied in this matter.
Id.
at 492-93, 81 A.3d 680. In its reasoning, the panel relied on
State v. Harris,
211
N.J.
566, 50 A.3d 15 (2012), as permitting exceptions to the exclusionary rule in limited circumstances.
Id.
at 490-91, 81 A.3d 680. The panel emphasized that, as in
Harris,
the exclusionary rule’s application would not serve as a deterrent in this case because the police relied upon valid precedent when conducting the search.
Id.
at 491, 81 A.3d 680.
Defendant filed a petition for certification, which was granted by this Court. 217
N.J.
588, 91 A.3d 24 (2014). We also granted amicus curiae status to the New Jersey State Bar Association (NJSBA).
II.
A.
Defendant argues that the Appellate Division misconstrued New Jersey law when it found that
McNeely
dramatically changed this State’s Fourth Amendment jurisprudence. According to defendant, neither federal nor New Jersey law recognized a per se exigency exception for warrantless blood draws of drunk driving suspects
pre-McNeely;
thus, the totality-of-the-cireumstances test always has been the appropriate standard. Nevertheless, citing
Wessells, supra,
209
N.J.
at 411-12, 37 A.3d 1122, defendant adds that federal retroactivity principles require application of
McNeely
to defendant’s case.
Importantly, on the issue of McNeely’s retroactive application, defendant and the State agree.
Consistent with his view of the prior state of federal and New Jersey law governing warrantless blood draws on the basis of alcohol dissipation alone, defendant argues that the officers were not following precedent when they procured his blood. Therefore, defendant contends that the Appellate Division erred in declining
to apply the exclusionary rule in this setting. He asserts that
Davis, supra,
—
U.S.
-, 131
S.Ct.
2419, 180
L.Ed.2d
285, is inapplicable, drawing support for that argument from the Supreme Court’s post
-McNeely
remand in
Brooks v. Minnesota,
—
U.S.
-, 133
S.Ct.
1996, 185
L.Ed.2d
863 (2013). That case involved a conviction based on a
pre-McNeely
warrantless blood test of a drunk driving suspect. Defendant points out (1) that the Supreme Court’s remand signaled its intent that
McNeely
be applied retroactively and (2) that the Court remanded without any mention that
Davis
applied.
Finally, defendant asserts that the Appellate Division’s decision is inconsistent with
Novembrino, supra,
105
N.J.
95, 519 A.2d 820, in which this Court declined to recognize a good faith exception to the exclusionary rule. Defendant argues that applying the exclusionary rule here furthers the rule’s purpose by protecting an individual’s Fourth Amendment rights and preserving judicial integrity through the exclusion of illegally obtained evidence. Defendant distinguishes
Harris, supra,
211
N.J.
566, 50 A.3d 15, noting that
Harris
did not involve a warrantless search, and emphasizes this Court’s statement in that case that it was not retreating from Novembrino’s rejection of a good faith exception to the exclusionary rule.
B.
The State concedes that
McNeely
should be given pipeline retroactive application. The State’s arguments focus instead on why it believes the exclusionary rule should not be applied to suppress defendant’s blood sample.
The State relies on the principles established by the United States Supreme Court in
Davis, supra,
which held that “when the police conduct a search in objectively reasonable reliance on binding appellate precedent, the exclusionary rule does not apply.”
-U.S.
at-, 131
S.Ct.
at 2434, 180 L.Ed.2d at 302. The State submits that the outcome produced by
Davis
on prior prosecutions is consistent with results reached under a New
Jersey retroactivity analysis when there is a change in the law. The State requests that this Court adopt an analogue to the
Davis
exclusionary-rule remedy, asserting that there is no practical difference between exclusion of evidence based on a retroactivity analysis premised on a change in law and exclusion of evidence based on an exception to the exclusionary rule.
The State further argues that although in
Novembrino, supra,
105
N.J.
at 157-58, 519 A.2d 820, our Court specifically rejected the good faith exception recognized in
United States v. Leon,
468
U.S.
897, 104
S.Ct.
3405, 82 L.Ed.2d 677 (1984), where the evidence sought to be suppressed was obtained by a police officer operating under the authority of a search warrant issued by a judge without a sufficient basis for probable cause, the Court has not rejected the good faith exception in
all
circumstances. The State highlights
Harris
as demonstrating this Court’s recognition that rigid application of the exclusionary rule is neither constitutionally mandated nor sound judicial policy in all circumstances.
The State adds that suppressing defendant’s blood samples in this case will not further any of the purposes for the exclusionary rule. Citing
State v. Ravotto,
169
N.J.
227, 777 A.2d 301 (2001), and
State v. Dyal,
97
N.J.
229, 478 A.2d 390 (1984), the State argues that although New Jersey courts have never explicitly used the term “exigency per se” to describe their interpretation of the
Schmerber
standard, it was universally understood that whenever police had probable cause to believe that a driver was intoxicated, they were authorized to obtain a blood test without a warrant. Thus, deterrence of police misconduct is not present here.
In sum, the State emphasizes that with
McNeely
there has been a shift in New Jersey Fourth Amendment jurisprudence such that a
Davis
good faith exception to the exclusionary rule’s application is warranted in these circumstances.
C.
Amicus NJSBA agrees with defendant that
McNeely
did not drastically change New Jersey’s Fourth Amendment jurispru
dence and that, therefore, no retroactivity or good faith analysis is required. That said, NJSBA agrees with all other parties that, if this Court finds that
McNeely
established a new rule of law, federal retroactivity principles mandate that it be applied retroactively to all eases in the pipeline, which includes this case. Even under New Jersey retroactivity law, NJSBA asserts
McNeely
would be applied to this case, noting that the purpose of
McNeely
was to re-affirm the totality-of-the-circumstances-based holding in
Schmerber,
and that “some reliance” by law enforcement on a different and more indulgent view of the law in New Jersey governing the exigency analysis when alcohol dissipation is at risk does not preclude retroactive application. Here the NJSBA contends that the State has not demonstrated that retroactive application would be burdensome.
NJSBA further asserts that no good faith exception to the exclusionary rule exists in New Jersey and that, were this Court to adopt
Davis,
we would essentially reverse the holding in
Novembrino.
NJSBA argues that the exclusionary rule serves dual purposes, one of which is to vindicate the Fourth Amendment right to be free from illegal searches, and to adopt
Davis
would undermine that purpose.

The United States Constitution and the New Jersey State Constitution both guarantee the right to be free from unreasonable searches and seizures.

Schmerber, supra,
384
U.S.
at 768, 86
S.Ct
at 1834, 16 L.Ed.2d at 918). “Because [this Court’s] constitutional jurisprudence generally favors warrants based on probable cause, all warrantless searches or seizures are presumptively unreason
able.”

Warrantless searches are “prohibited unless they fall within a recognized exception to the warrant requirement.”
State v. Penar-Flores,
198
N.J.
6, 18, 965 A.2d 114 (2009). One exception to that requirement is the presence of exigent circumstances.
Johnson, supra,
193
N.J.
at 552, 940 A.2d 1185. In assessing those circumstances, relevant factors include: “the urgency of the situation, the time it will take to secure a warrant, the seriousness of the crime under investigation, and
the threat that evidence will be destroyed or lost
or that the physical well-being of people will be endangered unless immediate action is taken.”
Id.
at 553, 940 A.2d 1185 (emphasis added). Traditionally, no one factor is dispositive and exigency must be assessed on a case-by-case basis under a totality-of-the-circumstances standard. See
State v. DeLuca,
168
N.J.
626, 632-33, 775 A.2d 1284 (2001).
In the context of the exigent-circumstances exception, the United States Supreme Court addressed the constitutionality of a warrantless blood draw from a suspected drunk driver in its 1966 decision in
Schmerber, supra,
384
U.S.
757, 86
S.Ct.
1826, 16
L.Ed.
2d 908. In
Schmerber,
the defendant was transported to the hospital for the treatment of injuries sustained in an automobile accident and was subsequently arrested on suspicion of drunk driving.
Id.
at 758, 86
S.Ct.
at 1829, 16 L.Ed.2d at 912. Without procuring a warrant, police directed hospital officials to draw a sample of the defendant’s blood; that sample was used to determine the defendant’s BAC level and, ultimately, to convict him of driving an automobile under the influence of alcohol.
Id.
at 758-59, 86
S.Ct.
at 1829, 16 L.Ed.2d at 912-13. In finding the warrantless blood draw constitutionally permissible, the Court concluded that although a warrant is typically required for the taking of blood,
[t]he officer in the present case ... might reasonably have believed that he was confronted with an emergency, in which the delay necessary to obtain a warrant, under the circumstances, threatened the destruction of evidence!.] We are told that the percentage of alcohol in the blood begins to diminish shortly after drinking
stops, as the body functions to eliminate it from the system. Particularly in a case such as this, where time had to be taken to bring the accused to a hospital and to investigate the scene of the accident, there was no time to seek out a magistrate and secure a warrant. Given these special facts, we conclude that the attempt to secure evidence of blood-alcohol content in this case was an appropriate incident to petitioner’s arrest.
[Id.
at 770-71, 86
S.Ct.
at 1835-36,
16 L.Ed.2d

The
Schmerber
Court added that the defendant’s blood was drawn by a reasonable method and in a reasonable manner.
Id.
at 771, 86
S.Ct.
at 1836, 16 L.Ed.2d at 920.
Following
Schmerber,
courts were not in universal agreement on whether the decision created a rule that the dissipation of alcohol constituted a per se exigency justifying a warrantless search.

and State v. Rodriguez,
156
P.
3d 771 (Utah 2007) (no per se rule). To resolve the split in authority over the application of
Schmerber,
the Supreme Court granted the State of Missouri’s petition for certiorari in
McNeely, supra,-U.S.
at-, 133
S.Ct.
at 1558, 185 L.Ed.2d at 703. In that case, the State of Missouri argued that “the fact that alcohol is naturally metabolized by the human body creates an exigent circumstance in every case.”
Id.
at-, 133
S.Ct.
at 1567, 185 L.Ed.2d at 713-14. On appeal, Missouri did not rely on any other factor in support of its claim that exigency for a warrantless draw of blood had been established.
Ibid.
In
McNeely,
the Court stated that
Schmerber
never created a per se rule but, instead, had incorporated a totality-of-the-circumstances test and had applied that test when assessing the facts presented in
Schmerber. Id.
at-, 133
S.Ct.
at 1558-60, 185
L.Ed.
2d at 704-06. The
McNeely
Court held that that same totality-of-the-circumstances test remains applicable whenever a
court must assess for exigency in the circumstances of a warrant-less search of a person suspected of driving under the influence, stating plainly that,
while
the natural dissipation of alcohol in the blood may support a finding of exigency in a specific case,
as it did in
Schmerber,
it does not do so categorically. Whether a warrantless blood test of a drunk-driving suspect is reasonable must be determined ease by case based on the totality of the circumstances.
[Id.
at-, 133
S.Ct.
at 1563,185 L.Ed.2d at 709 (emphasis added).]
Thus, the Supreme Court put to rest any ambiguity that existed following
Schmerber:
dissipation of alcohol from a person’s bloodstream is not the beginning and end of the analysis for exigency in all warrantless blood draws involving suspected drunk drivers. Rather, courts must evaluate the totality of the circumstances in assessing exigency, one factor of which is the human body’s natural dissipation of alcohol.
The present question before this Court is McNeely’s application to the warrantless drawing of defendant’s blood, which occurred prior to McNeely’s issuance.
IV.
In
Wessells, supra,
we recently addressed “both the meaning of and the retroactive effect to be given to [a] decision of the United States Supreme Court.” 209
N.J.
at 397, 37 A.3d 1122. In reviewing the question of retroactivity, we noted that “federal retroactivity turns on whether a new rule of law has been announced, coupled with an analysis of the status of the particular matter, that is, whether it is not yet final, is pending on direct appeal, or is being collaterally reviewed.”
Id.
at 411, 37 A.3d 1122. Our holding in
Wessells
recognized that if a new rule has been established “for the conduct of criminal prosecutions” it will “be applied retroactively to all cases, state or federal, pending on direct review or not yet final, with no exception for cases in which the new rule constitutes a ‘clear break’ with the past.”
Id.
at 412, 37 A.3d 1122 (quoting
Griffith v. Kentucky,
479
U.S.
314, 328, 107
S.Ct.
708, 716, 93 L.Ed.2d 649, 661 (1987)). Accordingly, we applied in
Wessells
a new rule of law, concerning invocation of the
right to counsel and the procedure for a suspect’s continued interrogation, that had been established in
Maryland v. Shatzer,
559
U.S.
98, 130
S.Ct.
1213, 175 L.Ed.2d 1045 (2010), to a case pending review in New Jersey at the time the decision was handed down.
Id.
at 413, 37 A.3d 1122.
As the Appellate Division found, and defendant and the State acknowledge, this case calls for a similar result under federal retroactivity law. The decision in
McNeely
may have been couched in terms that clarified Schmerbefs intent — namely, that
Schmerber
envisioned a totality-of-the-circumstances test would be applied in the review of warrantless blood draws of suspected DWI drivers and that the natural dissipation of the blood evidence would not establish per se exigency — but the
McNeely
Court nevertheless recognized that there was sufficient cause to grant certiorari to resolve an unsettled area of law, noting the split of authority around the country.
McNeely, supra,
—
U.S.
at-, 133
S.Ct.
at 1558, 185 L.Ed.2d at 703. In that respect, the decision represents new law settling an area of criminal practice. Under federal retroactivity law, the decision deserves pipeline retroactive application. The United States Supreme Court has pronounced the standard to be applied under the Fourth Amendment to warrantless searches involving blood draws of suspected DWI drivers and, under Supremacy Clause principles, we are bound to follow it as the minimal amount of constitutional protection to be provided.
Therefore, in accord with the practice followed in
Wessells, supra,
209
N.J.
395, 37 A.3d 1122, we hold that the Supreme Court’s decision in
McNeely
applies retroactively to cases that were in the pipeline when it was decided.
That said, the parties differ on whether the exclusionary rule should have any applicability in suppressing defendant’s blood test results when the police merely followed an asserted, commonly held understanding of
Schmerber’s
requirements in this State. Indeed, as defendant notes, following
McNeely,
the Supreme Court granted a writ of certiorari in
Brooks, supra,
—
U.S.
at
-, 133
S.Ct.
at 1996, 185
L.Ed.2d
at 863-64, a case involving a warrantless blood test of a drunk driving suspect, and the Court summarily vacated and remanded the decision of the Minnesota Court of Appeals. Defendant cites
Brooks
as support for his view on the intended pipeline retroactivity of
McNeely.
V.
Our Court is among those that have declined to recognize the exception to the exclusionary rule that was first established in
Leon, supra,
468
U.S.
897, 104
S.Ct.
3405, 82 L.Ed.2d 677.
In
Novembrino, supra,
we rejected a good faith exception to the exclusionary rule, relying on Article I, Paragraph 7, of the New Jersey Constitution. 105
N.J.
at 158-59, 519 A.2d 820. In not following the path recognized by
Leon,
our Court took the view that the good faith exception would, over time, “tend to undermine the motivation of law-enforcement officers to comply with the constitutional requirement of probable cause.”
Id.
at 152, 519 A.2d 820. The
Novembrino
Court concluded that suppressing evidence seized pursuant to invalid warrants would safeguard the integrity of the process by which warrants are sought and issued.
Id.
at 154, 519 A.2d 820 (“Our view that the good faith exception will ultimately reduce respect for and compliance with the probable-cause standard that we have steadfastly enforced persuades us that there is strong state interest that would be disserved by adopting the
Leon
rule.”).
Our State has consistently rejected a good faith exception to the exclusionary rule.
Post-Novembrino,
our Court’s adherence to its holding has remained steadfast and is not undermined by our recent conclusion in Harris,
In
Harris, supra,
we determined
that the exclusionary rule was ill-suited to the specific circumstances of evidence secured pursuant to a warrant issued based on a “reasonable cause” standard utilized in the Prevention of Domestic Violence Act where the illegal-on-sight nature of the seized evidence was immediately apparent. 211
N.J.
at 580, 587, 590, 50 A.3d 15 (noting that police did not engage in misconduct, did not err in execution of warrant, or disregard warrant’s parameters). Importantly, we cautioned that the determination “should not be understood ... as retreating from” the Court’s “earlier rejection of the good faith exception” in
Novembrino. Ibid.
Although the Appellate Division has applied a good faith approach to alterations in case law when engaging in a retroactivity analysis under New Jersey law,
see, e.g., State v. Skidmore,
253
N.J.Super.
227, 232-34, 601 A.2d 729 (App.Div.1992) (declining to exclude evidence found in search of defendant’s garbage, notwithstanding that search’s procedure did not comply with subsequent decision in
State v. Hempele,
120
N.J.
182, 576 A.2d 793 (1990)), this Court has never before embraced such an expansive approach to the exclusionary rule.
Cf. State v. Broom-Smith,
406
N.J.Super.
228, 238 n. 4, 967 A.2d 359 (App.Div.2009) (distinguishing
Novembrino
by focusing on its emphasis on safeguarding probable-cause standard, stating “[ujnlike
Novembrino,
this aspect of the case does not implicate a lack of probable cause for issuance of the warrant and does not implicate the same policy concerns underlying the Court’s rejection of the good faith doctrine”),

229, 989 A.2d 840 (2010).
In this matter we deal specifically with police conduct in reliance on case law in New Jersey that led law enforcement to the
reasonable conclusion that the natural dissipation of alcohol from the human body created exigency sufficient to dispense with the need to seek a warrant. Although our decisions never expressly pronounced an understanding of
Schmerber
that per se permitted warrantless blood draws in all cases on the basis of alcohol dissipation alone, case law contains language that provides a basis for such a belief.
See Ravotto, supra,
169
N.J.
227, 777 A.2d 301;
Dyal, supra,

N.J.
229, 478 A.2d 390.
In
Ravotto, supra,
while focused on the reasonableness of the force used by the police in procuring a blood sample, the Court noted that “consistent with
Schmerber
and our analogous case law, the dissipating nature of the alcohol content in defendant’s blood presented an exigency that required prompt action by the police.” 169
N.J.
at 250, 777 A.2d 301. In
Dyal, supra,
this Court addressed the application of the patient-physician privilege to the admission of the results of a BAC blood test. 97
N.J.
at 231, 478 A.2d 390. In that factual context, this Court noted that “the encounter between a patrolman and a drunken driver often arises in the context of an emergency,” that “[o]ne crucial consideration is that the body eliminates alcohol at a rapid rate,” and that “police, while coping with an emergency, should not be obliged to obtain a search warrant before seeking an involuntary blood test of a suspected drunken driver.”
Id.
at 239-40, 478 A.2d 390 (referencing
Schmerber
generally throughout). The Court added the more pointed statement, untethered to the specific facts therein presented, that “[a] drunken driver arrested by police with probable cause to believe he is intoxicated has no federal constitutional right to prevent the involuntary taking of a blood sample.”
Id.
at 238, 478 A.2d 390.
The Supreme Court has now clarified
the appropriate test to be applied to warrantless blood draws, and we will adhere to that test without any superimposed exception. That said, we accept that our case law played a leading role in dissuading police from believing that they needed to seek, or explaining why they did not seek, a warrant before obtaining an involuntary blood draw from a suspected drunk driver. With that in mind, we return to the touchstone of the Fourth Amendment— reasonableness.
State v. Bruzzese,
94
N.J.
210, 217, 463 A.2d 320 (1983).
In holding that we shall retroactively enforce the Supreme Court’s declaration that the totality-of-the-circumstances examination applies to all blood draws from suspected drunk drivers, we hold further that law enforcement should be permitted on remand in these pipeline cases to present to the court their basis for believing that exigency was present in the facts surrounding the evidence’s potential dissipation and police response under the circumstances to the events involved in the arrest. Further, the exigency in these circumstances should be assessed in a manner that permits the court to ascribe substantial weight to the perceived dissipation that an officer reasonably faced. Reasonableness of officers must be assessed in light of the existence of the
McNeely
opinion. But, in reexamining pipeline cases when police may have believed that they did not have to evaluate whether a warrant could be obtained, based on prior guidance from our Court that did not dwell on such an obligation, we direct reviewing courts to focus on the objective exigency of the circumstances that the officer faced in the situation.
