City of Indianapolis v. James Edmond

Justice O'CONNOR delivered the opinion of the Court.

In Michigan Dept. of State Police v. Sitz...and United States v. Martinez-Fuerte..., we held that brief, suspicionless seizures at highway checkpoints for the purposes of combating drunk driving and intercepting illegal immigrants were constitutional. We now consider the constitutionality of a highway checkpoint program whose primary purpose is the discovery and interdiction of illegal narcotics.

I

In August 1998, the city of Indianapolis began to operate vehicle checkpoints on Indianapolis roads in an effort to interdict unlawful drugs. The city conducted six such roadblocks between August and November that year, stopping 1,161 vehicles and arresting 104 motorists. Fifty-five arrests were for drug-related crimes, while 49 were for offenses unrelated to drugs. The overall “hit rate” of the program was thus approximately nine percent.

The parties stipulated to the facts concerning the operation of the checkpoints by the Indianapolis Police Department (IPD) for purposes of the preliminary injunction proceedings instituted below. At each checkpoint location, the police stop a predetermined number of vehicles. Approximately 30 officers are stationed at the checkpoint. Pursuant to written directives issued by the chief of police, at least one officer approaches the vehicle, advises the driver that he or she is being stopped briefly at a drug checkpoint, and asks the driver to produce a license and registration. The officer also looks for signs of impairment and conducts an open-view examination of the vehicle from the outside. A narcotics-detection dog walks around the outside of each stopped vehicle.

The directives instruct the officers that they may conduct a search only by consent or based on the appropriate quantum of particularized suspicion. The officers must conduct each stop in the same manner until particularized suspicion develops, and the officers have no discretion to stop any vehicle out of sequence. The city agreed in the stipulation to operate the checkpoints in such a way as to ensure that the total duration of each stop, absent reasonable suspicion or probable cause, would be five minutes or less.

Respondents James Edmond and Joell Palmer were each stopped at a narcotics checkpoint in late September 1998. Respondents then filed a lawsuit on behalf of themselves and the class of all motorists who had been stopped or were subject to being stopped in the future at the Indianapolis drug checkpoints. Respondents claimed that the roadblocks violated the Fourth Amendment of the United States Constitution and the search and seizure provision of the Indiana Constitution. Respondents requested declaratory and injunctive relief for the class, as well as damages and attorney's fees for themselves.

The Fourth Amendment requires that searches and seizures be reasonable. A search or seizure is ordinarily unreasonable in the absence of individualized suspicion of wrongdoing. While such suspicion is not an “irreducible” component of reasonableness, we have recognized only limited circumstances in which the usual rule does not apply. For example, we have upheld certain regimes of suspicionless searches where the program was designed to serve “special needs, beyond the normal need for law enforcement”....

We have also upheld brief, suspicionless seizures of motorists at a fixed Border Patrol checkpoint designed to intercept illegal aliens, Martinez-Fuerte, and at a sobriety checkpoint aimed at removing drunk drivers from the road, Michigan Dept. of State Police v. Sitz.... In addition, in Delaware v. Prouse...we suggested that a similar type of roadblock with the purpose of verifying drivers' licenses and vehicle registrations would be permissible. In none of these cases, however, did we indicate approval of a checkpoint program whose primary purpose was to detect evidence of ordinary criminal wrongdoing.

[...]

In Sitz, we evaluated the constitutionality of a Michigan highway sobriety checkpoint program. The Sitz checkpoint involved brief, suspicionless stops of motorists so that police officers could detect signs of intoxication and remove impaired drivers from the road. Motorists who exhibited signs of intoxication were diverted for a license and registration check and, if warranted, further sobriety tests. This checkpoint program was clearly aimed at reducing the immediate hazard posed by the presence of drunk drivers on the highways, and there was an obvious connection between the imperative of highway safety and the law enforcement practice at issue. The gravity of the drunk driving problem and the magnitude of the State's interest in getting drunk drivers off the road weighed heavily in our determination that the program was constitutional.

In Prouse, we invalidated a discretionary, suspicionless stop for a spot check of a motorist's driver's license and vehicle registration. The officer's conduct in that case was unconstitutional primarily on account of his exercise of “standardless and unconstrained discretion.” We nonetheless acknowledged the States' “vital interest in ensuring that only those qualified to do so are permitted to operate motor vehicles, that these vehicles are fit for safe operation, and hence that licensing, registration, and vehicle inspection requirements are being observed.” Accordingly, we suggested that “[q]uestioning of all oncoming traffic at roadblock-type stops” would be a lawful means of serving this interest in highway safety.

III

It is well established that a vehicle stop at a highway checkpoint effectuates a seizure within the meaning of the Fourth Amendment. The fact that officers walk a narcotics-detection dog around the exterior of each car at the Indianapolis checkpoints does not transform the seizure into a search. Just as in Place, an exterior sniff of an automobile does not require entry into the car and is not designed to disclose any information other than the presence or absence of narcotics. Like the dog sniff in Place, a sniff by a dog that simply walks around a car is “much less intrusive than a typical search.” Rather, what principally distinguishes these checkpoints from those we have previously approved is their primary purpose.

As petitioners concede, the Indianapolis checkpoint program unquestionably has the primary purpose of interdicting illegal narcotics. In their stipulation of facts, the parties repeatedly refer to the checkpoints as “drug checkpoints” ....

We have never approved a checkpoint program whose primary purpose was to detect evidence of ordinary criminal wrongdoing. Rather, our checkpoint cases have recognized only limited exceptions to the general rule that a seizure must be accompanied by some measure of individualized suspicion. We suggested in Prouse that we would not credit the “general interest in crime control” as justification for a regime of suspicionless stops. Consistent with this suggestion, each of the checkpoint programs that we have approved was designed primarily to serve purposes closely related to the problems of policing the border or the necessity of ensuring roadway safety. Because the primary purpose of the Indianapolis narcotics checkpoint program is to uncover evidence of ordinary criminal wrongdoing, the program contravenes the Fourth Amendment.

Petitioners propose several ways in which the narcotics-detection purpose of the instant checkpoint program may instead resemble the primary purposes of the checkpoints in Sitz and Martinez-Fuerte. Petitioners state that the checkpoints in those cases had the same ultimate purpose of arresting those suspected of committing crimes. Securing the border and apprehending drunk drivers are, of course, law enforcement activities, and law enforcement officers employ arrests and criminal prosecutions in pursuit of these goals. If we were to rest the case at this high level of generality, there would be little check on the ability of the authorities to construct roadblocks for almost any conceivable law enforcement purpose. Without drawing the line at roadblocks designed primarily to serve the general interest in crime control, the Fourth Amendment would do little to prevent such intrusions from becoming a routine part of American life.

Petitioners also emphasize the severe and intractable nature of the drug problem as justification for the checkpoint program. There is no doubt that traffic in illegal narcotics creates social harms of the first magnitude. The law enforcement problems that the drug trade creates likewise remain daunting and complex, particularly in light of the myriad forms of spin-off crime that it spawns. The same can be said of various other illegal activities, if only to a lesser degree. But the gravity of the threat alone cannot be dispositive of questions concerning what means law enforcement officers may employ to pursue a given purpose. Rather, in determining whether individualized suspicion is required, we must consider the nature of the interests threatened and their connection to the particular law enforcement practices at issue. We are particularly reluctant to recognize exceptions to the general rule of individualized suspicion where governmental authorities primarily pursue their general crime control ends.

[...]

The primary purpose of the Indianapolis narcotics checkpoints is in the end to advance “the general interest in crime control,” Prouse. We decline to suspend the usual requirement of individualized suspicion where the police seek to employ a checkpoint primarily for the ordinary enterprise of investigating crimes. We cannot sanction stops justified only by the generalized and ever-present possibility that interrogation and inspection may reveal that any given motorist has committed some crime.

[...]

Petitioners argue that the Indianapolis checkpoint program is justified by its lawful secondary purposes of keeping impaired motorists off the road and verifying licenses and registrations. If this were the case, however, law enforcement authorities would be able to establish checkpoints for virtually any purpose so long as they also included a license or sobriety check. For this reason, we examine the available evidence to determine the primary purpose of the checkpoint program. While we recognize the challenges inherent in a purpose inquiry, courts routinely engage in this enterprise in many areas of constitutional jurisprudence as a means of sifting abusive governmental conduct from that which is lawful. As a result, a program driven by an impermissible purpose may be proscribed while a program impelled by licit purposes is permitted, even though the challenged conduct may be outwardly similar. While reasonableness under the Fourth Amendment is predominantly an objective inquiry, our special needs and administrative search cases demonstrate that purpose is often relevant when suspicionless intrusions pursuant to a general scheme are at issue.

[...]

It goes without saying that our holding today does nothing to alter the constitutional status of the sobriety and border checkpoints that we approved in Sitz and Martinez-Fuerte, or of the type of traffic checkpoint that we suggested would be lawful in Prouse. The constitutionality of such checkpoint programs still depends on a balancing of the competing interests at stake and the effectiveness of the program. When law enforcement authorities pursue primarily general crime control purposes at checkpoints such as here, however, stops can only be justified by some quantum of individualized suspicion.

Our holding also does not affect the validity of border searches or searches at places like airports and government buildings, where the need for such measures to ensure public safety can be particularly acute. Nor does our opinion speak to other intrusions aimed primarily at purposes beyond the general interest in crime control. Our holding also does not impair the ability of police officers to act appropriately upon information that they properly learn during a checkpoint stop justified by a lawful primary purpose, even where such action may result in the arrest of a motorist for an offense unrelated to that purpose. Finally, we caution that the purpose inquiry in this context is to be conducted only at the programmatic level and is not an invitation to probe the minds of individual officers acting at the scene.

Because the primary purpose of the Indianapolis checkpoint program is ultimately indistinguishable from the general interest in crime control, the checkpoints violate the Fourth Amendment. The judgment of the Court of Appeals is, accordingly, affirmed.

It is so ordered.

Chief Justice REHNQUIST, with whom Justice THOMAS joins, and with whom Justice SCALIA joins as to Part I, dissenting.
The State's use of a drug-sniffing dog, according to the Court's holding, annuls what is otherwise plainly constitutional under our Fourth Amendment jurisprudence: brief, standardized, discretionless, roadblock seizures of automobiles, seizures which effectively serve a weighty state interest with only minimal intrusion on the privacy of their occupants. Because these seizures serve the State's accepted and significant interests of preventing drunken driving and checking for driver's licenses and vehicle registrations, and because there is nothing in the record to indicate that the addition of the dog sniff lengthens these otherwise legitimate seizures, I dissent.

I

As it is nowhere to be found in the Court's opinion, I begin with blackletter roadblock seizure law. “The principal protection of Fourth Amendment rights at checkpoints lies in appropriate limitations on the scope of the stop”.... Roadblock seizures are consistent with the Fourth Amendment if they are “carried out pursuant to a plan embodying explicit, neutral limitations on the conduct of individual officers.” Specifically, the constitutionality of a seizure turns upon “a weighing of the gravity of the public concerns served by the seizure, the degree to which the seizure advances the public interest, and the severity of the interference with individual liberty.”

[...]

Because of the valid reasons for conducting these roadblock seizures, it is constitutionally irrelevant that petitioners also hoped to interdict drugs. In Whren v. United States..., we held that an officer's subjective intent would not invalidate an otherwise objectively justifiable stop of an automobile. The reasonableness of an officer's discretionary decision to stop an automobile, at issue in Whren, turns on whether there is probable cause to believe that a traffic violation has occurred. The reasonableness of highway checkpoints, at issue here, turns on whether they effectively serve a significant state interest with minimal intrusion on motorists. The stop in Whren was objectively reasonable because the police officers had witnessed traffic violations; so too the roadblocks here are objectively reasonable because they serve the substantial interests of preventing drunken driving and checking for driver's licenses and vehicle registrations with minimal intrusion on motorists.

[...]

With these checkpoints serving two important state interests, the remaining prongs of the Brown v. Texas balancing test are easily met. The seizure is objectively reasonable as it lasts, on average, two to three minutes and does not involve a search. The subjective intrusion is likewise limited as the checkpoints are clearly marked and operated by uniformed officers who are directed to stop every vehicle in the same manner. The only difference between this case and Sitz is the presence of the dog. We have already held, however, that a “sniff test” by a trained narcotics dog is not a “search” within the meaning of the Fourth Amendment because it does not require physical intrusion of the object being sniffed and it does not expose anything other than the contraband items. And there is nothing in the record to indicate that the dog sniff lengthens the stop. Finally, the checkpoints' success rate-49 arrests for offenses unrelated to drugs-only confirms the State's legitimate interests in preventing drunken driving and ensuring the proper licensing of drivers and registration of their vehicles.

These stops effectively serve the State's legitimate interests; they are executed in a regularized and neutral manner; and they only minimally intrude upon the privacy of the motorists. They should therefore be constitutional.

II

The Court, unwilling to adopt the straightforward analysis that these precedents dictate, adds a new non-law-enforcement primary purpose test lifted from a distinct area of Fourth Amendment jurisprudence relating to the searches of homes and businesses. As discussed above, the question that the Court answers is not even posed in this case given the accepted reasons for the seizures. But more fundamentally, whatever sense a non-law-enforcement primary purpose test may make in the search setting, it is ill suited to brief roadblock seizures, where we have consistently looked at “the scope of the stop” in assessing a program's constitutionality.

We have already rejected an invitation to apply the non-law-enforcement primary purpose test that the Court now finds so indispensable. The respondents in Sitz argued that the Brown v. Texas balancing test was not the “proper method of analysis” with regards to roadblock seizures:

“Respondents argue that there must be a showing of some special governmental need ‘beyond the normal need’ for criminal law enforcement before a balancing analysis is appropriate, and that [the State] ha[s] demonstrated no such special need.

[...]

Petitioners' program complies with our decisions regarding roadblock seizures of automobiles, and the addition of a dog sniff does not add to the length or the intrusion of the stop. Because such stops are consistent with the Fourth Amendment, I would reverse the decision of the Court of Appeals.

Justice THOMAS, dissenting.

Taken together, our decisions in Michigan Dept. of State Police v. Sitz, and United States v. Martinez-Fuerte, stand for the proposition that suspicionless roadblock seizures are constitutionally permissible if conducted according to a plan that limits the discretion of the officers conducting the stops. I am not convinced that Sitz and Martinez-Fuerte were correctly decided. Indeed, I rather doubt that the Framers of the Fourth Amendment would have considered “reasonable” a program of indiscriminate stops of individuals not suspected of wrongdoing.

Respondents did not, however, advocate the overruling of Sitz and Martinez-Fuerte, and I am reluctant to consider such a step without the benefit of briefing and argument. For the reasons given by THE CHIEF JUSTICE, I believe that those cases compel upholding the program at issue here. I, therefore, join his opinion.
