Robbins v. California, 453 U.S. 420 (1981)

Syllabus

When California Highway Patrol officers stopped petitioner’s station wagon for proceeding erratically, they smelled marihuana smoke as he opened the car door. In the ensuing search of the car, the officers found in the luggage compartment two packages wrapped in green opaque plastic. They then unwrapped the packages, both of which contained bricks of marihuana. Petitioner was charged with various drug offenses, and, after his pretrial motion to suppress the evidence found when the packages were unwrapped was denied, he was convicted. The California Court of Appeal affirmed, holding that the warrantless opening of the packages was constitutionally permissible, since any experienced observer could reasonably have inferred from the appearance of the packages that they contained bricks of marihuana.

Held: The judgment is reversed. Pp.  453 U. S. 423-29;  453 U. S. 429-436.

103 Cal. App. 3d 34, 162 Cal. Rptr. 780, reversed.

JUSTICE STEWART, joined by JUSTICE BRENNAN, JUSTICE WHITE, and JUSTICE MARSHALL, concluded that the opening of the packages without a search warrant violated the Fourth and Fourteenth Amendments. Pp. 453 U. S. 423-429.

(a) A closed piece of luggage found in a lawfully searched car is constitutionally protected to the same extent as are closed pieces of luggage found anywhere else.  United States v. Chadwick, 433 U. S. 1; Arkansas v. Sanders, 442 U. S. 753. Pp.  453 U. S. 423-425.

(b) With respect to the constitutional protection to which a closed container found in the lawful search of an automobile is entitled, there is no distinction between containers, such as suitcases, commonly used to transport “personal effects,” i.e., property worn on or carried about the person or having some intimate relation to the person, and flimsier containers, such as cardboard boxes and plastic bags. Such a distinction has no basis in the language or meaning of the Fourth Amendment, which protects people and their effects, and protects those effects whether they are “personal” or “impersonal.” And there are no objective criteria by which such a distinction could be made. Pp.  453 U. S. 425-427.

(c) Unless a closed container found in an automobile is such that 

Page 453 U. S. 421

its contents may be said to be in plain view, those contents are fully protected by the Fourth Amendment. Here, the evidence was insufficient to justify an exception to the rule on the ground that the contents of the packages in question could be inferred from their outward appearance. To fall within such exception, a container must so clearly announce its contents, whether by its distinctive configuration, transparency, or otherwise, that its contents are obvious to the observer. Pp.  453 U. S. 427-428.

JUSTICE POWELL concluded that petitioner had a reasonable expectation of privacy in the opaquely wrapped and sealed package in question. The Fourth Amendment requires a police officer to obtain a warrant before searching a container that customarily serves as a repository for personal effects or when, as here, the circumstances indicate that the defendant has a reasonable expectation that the contents will not be open to public scrutiny. Pp.  453 U. S. 429-436.

STEWART, J., announced the judgment of the Court and delivered an opinion, in which BRENNAN, WHITE, and MARSHALL, JJ., joined. BURGER, C.J., concurred in the judgment. POWELL, J., filed an opinion concurring in the judgment, post, p.  453 U. S. 429. BLACKMUN, J., post, p.  453 U. S. 436, REHNQUIST, J., post, p.  453 U. S. 437, and STEVENS, J., post, p.  453 U.

Riley v. California, 573 U.S. 373 (2014)

Syllabus

RILEY v. CALIFORNIA

certiorari to the court of appeal of california, fourth appellate district, division one

No. 13–132. Argued April 29, 2014—Decided June 25, 2014[1]

In No. 13–132, petitioner Riley was stopped for a traffic violation, which eventually led to his arrest on weapons charges. An officer searching Riley incident to the arrest seized a cell phone from Riley’s pants pocket. The officer accessed information on the phone and noticed the repeated use of a term associated with a street gang. At the police station two hours later, a detective specializing in gangs further examined the phone’s digital contents. Based in part on photographs and videos that the detective found, the State charged Riley in connection with a shooting that had occurred a few weeks earlier and sought an enhanced sentence based on Riley’s gang membership. Riley moved to suppress all evidence that the police had obtained from his cell phone. The trial court denied the motion, and Riley was convicted. The California Court of Appeal affirmed. 

In No. 13–212, respondent Wurie was arrested after police observed him participate in an apparent drug sale. At the police station, the officers seized a cell phone from Wurie’s person and noticed that the phone was receiving multiple calls from a source identified as “my house” on its external screen. The officers opened the phone, accessed its call log, determined the number associated with the “my house” label, and traced that number to what they suspected was Wurie’s apartment. They secured a search warrant and found drugs, a firearm and ammunition, and cash in the ensuing search. Wurie was then charged with drug and firearm offenses. He moved to suppress the evidence obtained from the search of the apartment. The District Court denied the motion, and Wurie was convicted. The First Circuit reversed the denial of the motion to suppress and vacated the relevant convictions.

Held: The police generally may not, without a warrant, search digital information on a cell phone seized from an individual who has been arrested. Pp. 5–28.

(a) A warrantless search is reasonable only if it falls within a specific exception to the Fourth Amendment’s warrant requirement. See Kentucky v. King, 563 U. S. ___, ___. The well-established exception at issue here applies when a warrantless search is conducted incident to a lawful arrest. 

Three related precedents govern the extent to which officers may search property found on or near an arrestee.  Chimel v. California, 395 U.S. 752, requires that a search incident to arrest be limited to the area within the arrestee’s immediate control, where it is justified by the interests in officer safety and in preventing evidence destruction. In United States v. Robinson, 414 U.S. 218, the Court applied the Chimelanalysis to a search of a cigarette pack found on the arrestee’s person. It held that the risks identified in Chimel are present in all custodial arrests, 414 U. S., at 235, even when there is no specific concern about the loss of evidence or the threat to officers in a particular case, id., at 236. The trilogy concludes with Arizona v. Gant, 556 U.S. 332, which permits searches of a car where the arrestee is unsecured and within reaching distance of the passenger compartment, or where it is reasonable to believe that evidence of the crime of arrest might be found in the vehicle, id., at 343. Pp. 5–8.

(b) The Court declines to extend Robinson’s categorical rule to searches of data stored on cell phones. Absent more precise guidance from the founding era, the Court generally determines whether to exempt a given type of search from the warrant requirement “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.”  Wyoming v. Houghton, 526 U.S. 295, 300. That balance of interests supported the search incident to arrest exception in Robinson. But a search of digital information on a cell phone does not further the government interests identified in Chimel, and implicates substantially greater individual privacy interests than a brief physical search. Pp. 8–22.

(1) The digital data stored on cell phones does not present either Chimel risk. Pp. 10–15.

(i) Digital data stored on a cell phone cannot itself be used as a weapon to harm an arresting officer or to effectuate the arrestee’s escape. Officers may examine the phone’s physical aspects to ensure that it will not be used as a weapon, but the data on the phone can endanger no one. To the extent that a search of cell phone data might warn officers of an impending danger, e.g., that the arrestee’s confederates are headed to the scene, such a concern is better addressed through consideration of case-specific exceptions to the warrant requirement, such as exigent circumstances. See, e.g., Warden, Md. Penitentiary v. Hayden387 U.S. 294, 298–299. Pp. 10–12.

(ii) The United States and California raise concerns about the destruction of evidence, arguing that, even if the cell phone is physically secure, information on the cell phone remains vulnerable to remote wiping and data encryption. As an initial matter, those broad concerns are distinct from Chimel’s focus on a defendant who responds to arrest by trying to conceal or destroy evidence within his reach. The briefing also gives little indication that either problem is prevalent or that the opportunity to perform a search incident to arrest would be an effective solution. And, at least as to remote wiping, law enforcement currently has some technologies of its own for combatting the loss of evidence. Finally, law enforcement’s remaining concerns in a particular case might be addressed by responding in a targeted manner to urgent threats of remote wiping, see Missouri v. McNeely, 569 U. S. ___, ___, or by taking action to disable a phone’s locking mechanism in order to secure the scene, see Illinois v. McArthur, 531 U.S. 326, 331–333. Pp. 12–15.

(2) A conclusion that inspecting the contents of an arrestee’s pockets works no substantial additional intrusion on privacy beyond the arrest itself may make sense as applied to physical items, but more substantial privacy interests are at stake when digital data is involved. Pp. 15–22.

(i) Cell phones differ in both a quantitative and a qualitative sense from other objects that might be carried on an arrestee’s person. Notably, modern cell phones have an immense storage capacity. Before cell phones, a search of a person was limited by physical realities and generally constituted only a narrow intrusion on privacy. But cell phones can store millions of pages of text, thousands of pictures, or hundreds of videos. This has several interrelated privacy consequences. First, a cell phone collects in one place many distinct types of information that reveal much more in combination than any isolated record. Second, the phone’s capacity allows even just one type of information to convey far more than previously possible. Third, data on the phone can date back for years. In addition, an element of pervasiveness characterizes cell phones but not physical records. A decade ago officers might have occasionally stumbled across a highly personal item such as a diary, but today many of the more than 90% of American adults who own cell phones keep on their person a digital record of nearly every aspect of their lives. Pp. 17–21.

(ii) The scope of the privacy interests at stake is further complicated by the fact that the data viewed on many modern cell phones may in fact be stored on a remote server. Thus, a search may extend well beyond papers and effects in the physical proximity of an arrestee, a concern that the United States recognizes but cannot definitively foreclose. Pp. 21–22.

(c) Fallback options offered by the United States and California are flawed and contravene this Court’s general preference to provide clear guidance to law enforcement through categorical rules. See Michigan v. Summers, 452 U.S. 692, 705, n. 19. One possible rule is to import the Gant standard from the vehicle context and allow a warrantless search of an arrestee’s cell phone whenever it is reasonable to believe that the phone contains evidence of the crime of arrest. That proposal is not appropriate in this context, and would prove no practical limit at all when it comes to cell phone searches. Another possible rule is to restrict the scope of a cell phone search to information relevant to the crime, the arrestee’s identity, or officer safety. That proposal would again impose few meaningful constraints on officers. Finally, California suggests an analogue rule, under which officers could search cell phone data if they could have obtained the same information from a pre-digital counterpart. That proposal would allow law enforcement to search a broad range of items contained on a phone even though people would be unlikely to carry such a variety of information in physical form, and would launch courts on a difficult line-drawing expedition to determine which digital files are comparable to physical records. Pp. 22–25.

(d) It is true that this decision will have some impact on the ability of law enforcement to combat crime. But the Court’s holding is not that the information on a cell phone is immune from search; it is that a warrant is generally required before a search. The warrant requirement is an important component of the Court’s Fourth Amendment jurisprudence, and warrants may be obtained with increasing efficiency. In addition, although the search incident to arrest exception does not apply to cell phones, the continued availability of the exigent circumstances exception may give law enforcement a justification for a warrantless search in particular cases. Pp. 25–27.

No. 13–132, reversed and remanded; No. 13–212, 728 F.3d 1, affirmed.

Rawlings v. Kentucky, 448 U.S. 98 (1980)

Syllabus

When police officers, armed with a warrant to arrest one Marquess, arrived at his house, another resident of the house and four visitors, including petitioner, were there. While searching the house unsuccessfully for Marquess, several officers smelled marihuana smoke and saw marihuana seeds. Two of the officers left to obtain a warrant to search the house, and the other officers detained the occupants, allowing them to leave only if they consented to a body search. About 45 minutes later, the officers returned with the search warrant; the warrant was read to the remaining occupants, including petitioner, and they were also given Miranda warnings; and one Cox, an occupant, was ordered to empty her purse, which contained drugs that were controlled substances under Kentucky law. Cox told petitioner, who was standing nearby in response to an officer’s command, “to take what was his,” and petitioner immediately claimed ownership of the drugs. At that time, an officer searched petitioner, finding $ 4,500 in cash and a knife, and petitioner was then formally arrested. Petitioner was indicted for possessing with intent to sell the controlled substances recovered from Cox’s purse, and the Kentucky trial court denied petitioner’s motion to suppress, as fruits of an illegal detention and illegal searches, the drugs, the money, and the statements made by him when the police discovered the drugs. Petitioner’s conviction was affirmed by the Kentucky Court of Appeals, and the Kentucky Supreme Court, in turn affirmed, holding that petitioner had no “standing” to contest the search of Cox’s purse because he had no legitimate or reasonable expectation of freedom from governmental intrusion into the purse, and that the search uncovering the money in petitioner’s pocket was justifiable as incident to a lawful arrest based on probable cause.

Held:

1. The conclusion that petitioner did not sustain his burden of proving that he had a legitimate expectation of privacy in Cox’s purse so as to allow him to challenge the validity of the search of the purse is supported by the record, which includes petitioner’s admission at the suppression hearing that he did not believe that the purse would be free from governmental intrusion. Nor was petitioner entitled to challenge 

Page 448 U. S. 99

the search, regardless of his expectation of privacy, merely because he claimed ownership of the drugs in the purse. While petitioner’s ownership of the drugs is one fact to be considered, “arcane” concepts of property law do not control the ability to claim the protections of the Fourth Amendment.  Cf. Rakas v. Illinois,439 U. S. 128. Pp.  448 U. S. 104-106.

2. Under the totality of circumstances present (the giving of Miranda warnings, the short lapse of time between petitioner’s detention and his admissions being outweighed by the “congenial atmosphere” in the house during this interval, his admissions being apparently spontaneous reactions to the discovery of the drugs in Cox’s purse, the police conduct not appearing to rise to the level of conscious or flagrant misconduct requiring prophylactic exclusion of petitioner’s admissions, and petitioner not having argued that his admissions were anything other than voluntary), Kentucky carried its burden of showing that petitioner’s statements to the police admitting his ownership of the drugs were acts of free will unaffected by any illegality in his detention, assuming, arguendo, that the police violated the Fourth and Fourteenth Amendments by detaining petitioner and his companions in the house while they obtained a search warrant.  Cf. Brown v. Illinois, 422 U. S. 590. Pp.  448 U. S. 106-110.

3. The search of petitioner’s person that uncovered the money and the knife was valid as incident to his formal arrest. Once he admitted ownership of the drugs found in Cox’s purse, the police had probable cause to arrest him, and where the arrest followed quickly after the search of petitioner’s person it is not important that the search preceded the arrest, rather than vice versa. Pp.  448 U. S. 110-111.

Pennsylvania v. Mimms, 434 U.S. 106 (1977)

Syllabus

After police officers had stopped respondent’s automobile for being operated with an expired license plate, one of the officers asked respondent to step out of the car and produce his license and registration. As respondent alighted, a large bulge under his jacket was noticed by the officer, who thereupon frisked him and found a loaded revolver. Respondent was then arrested and subsequently indicted for carrying a concealed weapon and unlicensed firearm. His motion to suppress the revolver was denied and after a trial, at which the revolver was introduced in evidence, he was convicted. The Pennsylvania Supreme Court reversed on the ground that the revolver was seized in violation of the Fourth Amendment.

Held:

1. The order to get out of the car, issued after the respondent was lawfully detained, was reasonable, and thus permissible under the Fourth Amendment. The State’s proffered justification for such order — the officer’s safety — is both legitimate and weighty, and the intrusion into respondent’s personal liberty occasioned by the order, being, at most, a mere inconvenience, cannot prevail when balanced against legitimate concerns for the officer’s safety.

2. Under the standard announced in Terry v. Ohio, 392 U. S. 1,  392 U. S. 21-22 — whether

“the facts available to the officer at the moment of the seizure or the search ‘warrant a man of reasonable caution in the belief’ that the action taken was appropriate”

— the officer was justified in making the search he did once the bulge in respondent’s jacket was observed.

Certiorari granted; 471 Pa. 546, 370 A.2d 1157, reversed and remanded.

Pennsylvania v. Labron, 518 U.S. 938 (1996)

PENNSYLVANIA v. LABRON

ON PETITION FOR WRIT OF CERTIORARI TO THE SUPREME COURT OF PENNSYLVANIA

No. 95-1691. Decided July 1, 1996*

In No. 95-1691, police found cocaine when they searched the trunk of respondent Labron’s car after observing him and others engaging in drug transactions on a Philadelphia street. In No. 95-1738, a search of respondent Kilgore’s truck during a drug raid on his home turned up cocaine. In both cases, probable cause existed for the searches, but the police did not obtain warrants. The Pennsylvania Supreme Court suppressed the evidence seized in each case, holding that the Fourth Amendment requires police to obtain a warrant before searching an automobile unless exigent circumstances are present.

Held: The automobile exception to the Fourth Amendment’s warrant requirement requires only that there be probable cause to conduct a search. This Court’s early cases establishing the automobile exception were based on the automobile’s ready mobility, an exigency sufficient to excuse failure to obtain a search warrant once probable cause to conduct the search is clear. See, e. g., California v. Carney, 471 U. S. 386,390391. More recent cases provide a further justification: the individual’s reduced privacy expectation in an automobile, owing to its pervasive regulation. Ibid. This Court’s jurisdiction in Labron’s case is secure. The Commonwealth’s automobile exception jurisprudence appears to be interwoven with federal law, and the adequacy and independence of any possible state-law ground for the exception is not clear from the face of the Pennsylvania Supreme Court’s opinion. Michigan v. Long, 463 U. S. 1032, 1040-1041. Since the opinion in Kilgore’s case rests on the explicit conclusion that the officers’ conduct violated the Fourth Amendment, this Court has jurisdiction to review that judgment as well.

Certiorari granted; No. 95-1691, 543 Pa. 86, 669 A. 2d 917, and No. 951738,544 Pa. 439, 677 A. 2d 311, reversed and remanded.

PER CURIAM.

In these two cases, the Supreme Court of Pennsylvania held that the Fourth Amendment, as applied to the States through the Fourteenth, requires police to obtain a warrant

*Together with No. 95-1738, Pennsylvania v. Kilgore, also on petition for writ of certiorari to the same court.

before searching an automobile unless exigent circumstances are present. Because the holdings rest on an incorrect reading of the automobile exception to the Fourth Amendment’s warrant requirement, we grant the petitions for certiorari and reverse.

In Labron, No. 95-1691, police observed respondent Labron and others engaging in a series of drug transactions on a street in Philadelphia. The police arrested the suspects, searched the trunk of a car from which the drugs had been produced, and found bags containing cocaine. The Pennsylvania Supreme Court agreed with the trial court (but not with the intermediate court of appeals, 428 Pa. Super. 616, 626 A. 2d 646 (1993), whose judgment it reversed) that this evidence should be suppressed. 543 Pa. 86, 669 A. 2d 917 (1995). After surveying our precedents on the automobile exception as well as some of its own decisions, the court “conclude[d] that this Commonwealth’s jurisprudence of the automobile exception has long required both the existence of probable cause and the presence of exigent circumstances to justify a warrantless search.” Id., at 100, 669 A. 2d, at 924. Satisfied the police had time to secure a warrant, id., at 100103, 699 A. 2d, at 924-925, the court held that “the warrantless search of this stationary vehicle violated constitutional guarantees,” id., at 101, 669 A. 2d, at 924.

In Kilgore, No. 95-1738, an undercover informant agreed to buy drugs from respondent Randy Lee Kilgore’s accomplice, Kelly Jo Kilgore. To obtain the drugs, Kelly Jo drove from the parking lot where the deal was made to a farmhouse where she met with Randy Kilgore and obtained the drugs. After the drugs were delivered and the Kilgores were arrested, police searched the farmhouse with the consent of its owner and also searched Randy Kilgore’s pickup truck; they had seen the Kilgores walking to and from the truck, which was parked in the driveway of the farmhouse. The search turned up cocaine on the truck’s floor. The trial court denied Randy Kilgore’s motion to suppress the cocaine, holding the officers had probable cause to make the search.

Payton v. New York, 445 U.S. 573 (1980)

Syllabus

These appeals challenge the constitutionality of New York statutes authorizing police officers to enter a private residence without a warrant and with force, if necessary, to make a routine felony arrest. In each of the appeals, police officers, acting with probable cause but without warrants, had gone to the appellant’s residence to arrest the appellant on a felony charge and had entered the premises without the consent of any occupant. In each case, the New York trial judge held that the warrantless entry was authorized by New York statutes and refused to suppress evidence that was seized upon the entry. Treating both cases as involving routine arrests in which there was ample time to obtain a warrant, the New York Court of Appeals, in a single opinion, ultimately affirmed the convictions of both appellants.

Held: The Fourth Amendment, made applicable to the States by the Fourteenth Amendment, prohibits the police from making a warrantless and nonconsensual entry into a suspect’s home in order to make a routine felony arrest. Pp.  445 U. S. 583-603.

(a) The physical entry of the home is the chief evil against which the wording of the Fourth Amendment is directed. To be arrested in the home involves not only the invasion attendant to all arrests, but also an invasion of the sanctity of the home, which is too substantial an invasion to allow without a warrant, in the absence of exigent circumstances, even when it is accomplished under statutory authority and when probable cause is present. In terms that apply equally to seizures of property and to seizures of persons, the Fourth Amendment has drawn a firm line at the entrance to the house. Absent exigent circumstances, that threshold may not reasonably be crossed without a warrant. Pp  445 U. S. 583-590.

(b) The reasons for upholding warrantless arrests in a public place, cf. United States v. Watson, 423 U. S. 411, do not apply to warrantless invasions of the privacy of the home. The common law rule on warrantless home arrests was not as clear as the rule on arrests in public places; the weight of authority as it appeared to the Framers of the 

Page 445 U. S. 574

Fourth Amendment was to the effect that a warrant was required for a home arrest, or, at the minimum, that there were substantial risks in proceeding without one. Although a majority of the States that have taken a position on the question permit warrantless home arrests even in the absence of exigent circumstances, there is an obvious declining trend, and there is by no means the kind of virtual unanimity on this question that was present in United States v. Watson, supra, with regard to warrantless public arrests. And, unlike the situation in Watson, no federal statutes have been cited to indicate any congressional determination that warrantless entries into the home are “reasonable.” Pp.  445 U. S. 590-601.

(c) For Fourth Amendment purposes, an arrest warrant founded on probable cause implicitly carries with it the limited authority to enter a dwelling in which the suspect lives when there is reason to believe the suspect is within. Pp.  445 U. S. 602-603.

45 N.Y.2d 300, 380 N.E.2d 224, reversed and remanded.

Ohio v. Robinette, 519 U.S. 33 (1996)

Syllabus

OHIO v. ROBINETTE

CERTIORARI TO THE SUPREME COURT OF OHIO No.95-891. Argued October 8, 1996-Decided November 18,1996

After an Ohio deputy sheriff stopped respondent Robinette for speeding, gave him a verbal warning, and returned his driver’s license, the deputy asked whether he was carrying illegal contraband, weapons, or drugs in his car. Robinette answered “no” and consented to a search of the car, which revealed a small amount of marijuana and a pill. He was arrested and later charged with knowing possession of a controlled substance when the pill turned out to be methylenedioxymethamphetamine. Following denial of his pretrial suppression motion, he was found guilty, but the Ohio Court of Appeals reversed on the ground that the search resulted from an unlawful detention. The State Supreme Court affirmed, establishing as a bright-line prerequisite for consensual interrogation under these circumstances the requirement that an officer clearly state when a citizen validly detained for a traffic offense is “legally free to go.”

Held:

1. This Court has jurisdiction to review the Ohio Supreme Court’s decision. The contention that jurisdiction is lacking because the Ohio decision rested in part upon the State Constitution is rejected under Michigan v. Long, 463 U. S. 1032, 1040-1041. Although the opinion below mentions the Ohio Constitution in passing, it clearly relies on federal law, discussing and citing federal cases almost exclusively. It is not dispositive that those citations appear only in the opinion and not in the official syllabus. Under Zacchini v. Scripps-Howard Broadcasting Co., 433 U. S. 562, 566, it is permissible to turn to an Ohio opinion’s body when the syllabus speaks only in general terms of “the federal and Ohio Constitutions.” Nor is the Court’s jurisdiction defeated by the additional holding below that continuing detention of a person stopped for a traffic violation constitutes an illegal seizure when the officer’s motivation for continuing is not related to the purpose of the original, constitutional stop and there are no articulable facts giving rise to a suspicion of some separate illegal activity. Under Whren v. United States, 517 U. S. 806, 813, the officer’s subjective intentions do not make continued detention illegal, so long as the detention is justified by the circumstances viewed objectively. Pp. 36-39.

2. The Fourth Amendment does not require that a lawfully seized defendant be advised that he is “free to go” before his consent to search

Syllabus

will be recognized as voluntary. The Amendment’s touchstone is reasonableness, which is measured in objective terms by examining the totality of the circumstances. In applying this test, the Court has consistently eschewed bright-line rules, instead emphasizing the factspecific nature of the reasonableness inquiry. Indeed, in rejecting a per se rule very similar to one adopted below, this Court has held that the voluntariness of a consent to search is a question of fact to be determined from all the circumstances. Schneckloth v. Bustamonte, 412 U. S. 218, 248-249. The Ohio Supreme Court erred in holding otherwise. It would be unrealistic to require the police to always inform detainees that they are free to go before a consent to search may be deemed voluntary. Cf. id., at 231. Pp. 39-40.

New Jersey v. T.L.O., 469 U.S. 325 (1985)

Syllabus

A teacher at a New Jersey high school, upon discovering respondent, then a 14-year-old freshman, and her companion smoking cigarettes in a school lavatory in violation of a school rule, took them to the Principal’s office, where they met with the Assistant Vice Principal. When respondent, in response to the Assistant Vice Principal’s questioning, denied that she had been smoking and claimed that she did not smoke at all, the Assistant Vice Principal demanded to see her purse. Upon opening the purse, he found a pack of cigarettes and also noticed a package of cigarette rolling papers that are commonly associated with the use of marihuana. He then proceeded to search the purse thoroughly and found some marihuana, a pipe, plastic bags, a fairly substantial amount of money, an index card containing a list of students who owed respondent money, and two letters that implicated her in marihuana dealing. Thereafter, the State brought delinquency charges against respondent in the Juvenile Court, which, after denying respondent’s motion to suppress the evidence found in her purse, held that the Fourth Amendment applied to searches by school officials, but that the search in question was a reasonable one, and adjudged respondent to be a delinquent. The Appellate Division of the New Jersey Superior Court affirmed the trial court’s finding that there had been no Fourth Amendment violation, but vacated the adjudication of delinquency and remanded on other grounds. The New Jersey Supreme Court reversed and ordered the suppression of the evidence found in respondent’s purse, holding that the search of the purse was unreasonable.

Held:

1. The Fourth Amendment’s prohibition on unreasonable searches and seizures applies to searches conducted by public school officials, and is not limited to searches carried out by law enforcement officers. Nor are school officials exempt from the Amendment’s dictates by virtue of the special nature of their authority over schoolchildren. In carrying out searches and other functions pursuant to disciplinary policies mandated by state statutes, school officials act as representatives of the State, not merely as surrogates for the parents of students, and they cannot claim the parents immunity from the Fourth Amendment’s strictures. Pp.  469 U. S. 333-337. 

Page 469 U. S. 326

2. Schoolchildren have legitimate expectations of privacy. They may find it necessary to carry with them a variety of legitimate, noncontraband items, and there is no reason to conclude that they have necessarily waived all rights to privacy in such items by bringing them onto school grounds. But striking the balance between schoolchildren’s legitimate expectations of privacy and the school’s equally legitimate need to maintain an environment in which learning can take place requires some easing of the restrictions to which searches by public authorities are ordinarily subject. Thus, school officials need not obtain a warrant before searching a student who is under their authority. Moreover, school officials need not be held subject to the requirement that searches be based on probable cause to believe that the subject of the search has violated or is violating the law. Rather, the legality of a search of a student should depend simply on the reasonableness, under all the circumstances, of the search. Determining the reasonableness of any search involves a determination of whether the search was justified at its inception and whether, as conducted, it was reasonably related in scope to the circumstances that justified the interference in the first place. Under ordinary circumstances, the search of a student by a school official will be justified at its inception where there are reasonable grounds for suspecting that the search will turn up evidence that the student has violated or is violating either the law or the rules of the school. And such a search will be permissible in its scope when the measures adopted are reasonably related to the objectives of the search, and not excessively intrusive in light of the student’s age and sex and the nature of the infraction. Pp.  469 U. S. 337-343.

3. Under the above standard, the search in this case was not unreasonable for Fourth Amendment purposes. First, the initial search for cigarettes was reasonable. The report to the Assistant Vice Principal that respondent had been smoking warranted a reasonable suspicion that she had cigarettes in her purse, and thus the search was justified despite the fact that the cigarettes, if found, would constitute “mere evidence” of a violation of the no-smoking rule. Second, the discovery of the rolling papers then gave rise to a reasonable suspicion that respondent was carrying marihuana as well as cigarettes in her purse, and this suspicion justified the further exploration that turned up more evidence of drug-related activities. Pp.  469 U. S. 343-347.

Minnesota v. Dickerson, 508 U.S. 366 (1993)

Syllabus

MINNESOTA v. DICKERSON

CERTIORARI TO THE SUPREME COURT OF MINNESOTA No. 91-2019. Argued March 3, 1993-Decided June 7, 1993

Based upon respondent’s seemingly evasive actions when approached by police officers and the fact that he had just left a building known for cocaine traffic, the officers decided to investigate further and ordered respondent to submit to a patdown search. The search revealed no weapons, but the officer conducting it testified that he felt a small lump in respondent’s jacket pocket, believed it to be a lump of crack cocaine upon examining it with his fingers, and then reached into the pocket and retrieved a small bag of cocaine. The state trial court denied respondent’s motion to suppress the cocaine, and he was found guilty of possession of a controlled substance. The Minnesota Court of Appeals reversed. In affirming, the State Supreme Court held that both the stop and the frisk of respondent were valid under Terry v. Ohio, 392 U. S. 1, but found the seizure of the cocaine to be unconstitutional. Refusing to enlarge the “plain-view” exception to the Fourth Amendment’s warrant requirement, the court appeared to adopt a categorical rule barring the seizure of any contraband detected by an officer through the sense of touch during a patdown search. The court further noted that, even if it recognized such a “plain-feel” exception, the search in this case would not qualify because it went far beyond what is permissible under Terry.

Held:

1. The police may seize nonthreatening contraband detected through the sense of touch during a protective patdown search of the sort permitted by Terry, so long as the search stays within the bounds marked by Terry. pp.372-377.

(a) Terry permits a brief stop of a person whose suspicious conduct leads an officer to conclude in light of his experience that criminal activity may be afoot, and a patdown search of the person for weapons when the officer is justified in believing that the person may be armed and presently dangerous. This protective search-permitted without a warrant and on the basis of reasonable suspicion less than probable cause-is not meant to discover evidence of crime, but must be strictly limited to that which is necessary for the discovery of weapons which might be used to harm the officer or others. If the protective search goes beyond what is necessary to determine if the suspect is armed, it

367

is no longer valid under Terry and its fruits will be suppressed. Sibron v. New York, 392 U. S. 40, 65-66. pp. 372-373.

(b) In Michigan v. Long, 463 U. S. 1032, 1050, the seizure of contraband other than weapons during a lawful Terry search was justified by reference to the Court’s cases under the “plain-view” doctrine. That doctrine-which permits police to seize an object without a warrant if they are lawfully in a position to view it, if its incriminating character is immediately apparent, and if they have a lawful right of access to it-has an obvious application by analogy to cases in which an officer discovers contraband through the sense of touch during an otherwise lawful search. Thus, if an officer lawfully pats down a suspect’s outer clothing and feels an object whose contour or mass makes its identity immediately apparent, there has been no invasion of the suspect’s privacy beyond that already authorized by the officer’s search for weapons. Cf., e. g., Illinois v. Andreas, 463 U. S. 765, 771. If the object is contraband, its warrantless seizure would be justified by the realization that resort to a neutral magistrate under such circumstances would be impracticable and would do little to promote the Fourth Amendment’s objectives. Cf., e. g., Arizona v. Hicks, 480 U. S. 321, 326-327. Pp. 374-377.

2. Application of the foregoing principles to the facts of this case demonstrates that the officer who conducted the search was not acting within the lawful bounds marked by Terry at the time he gained probable cause to believe that the lump in respondent’s jacket was contraband. Under the State Supreme Court’s interpretation of the record, the officer never thought that the lump was a weapon, but did not immediately recognize it as cocaine. Rather, he determined that it was contraband only after he squeezed, slid, and otherwise manipulated the pocket’s contents. While Terry entitled him to place his hands on respondent’s jacket and to feel the lump in the pocket, his continued exploration of the pocket after he concluded that it contained no weapon was unrelated to the sole justification for the search under Terry. Because this further search was constitutionally invalid, the seizure of the cocaine that followed is likewise unconstitutional. Pp. 377-379.

Minnesota v. Carter, 525 U.S. 83 (1998)

Syllabus

MINNESOTA v. CARTER

CERTIORARI TO THE SUPREME COURT OF MINNESOTA

No. 97-1147. Argued October 6, 1998-Decided December 1, 1998*

A police officer looked in an apartment window through a gap in the closed blind and observed respondents Carter and Johns and the apartment’s lessee bagging cocaine. After respondents were arrested, they moved to suppress, inter alia, cocaine and other evidence obtained from the apartment and their car, arguing that the officer’s initial observation was an unreasonable search in violation of the Fourth Amendment. Respondents were convicted of state drug offenses. The Minnesota trial court held that since they were not overnight social guests, they were not entitled to Fourth Amendment protection, and that the officer’s observation was not a search under the Amendment. The State Court of Appeals held that Carter did not have “standing” to object to the officer’s actions because the evidence indicated that he used the apartment for a business purpose-to package drugs-and, separately, affirmed Johns’ conviction without addressing the “standing” issue. In reversing, the State Supreme Court held that respondents had “standing” to claim Fourth Amendment protection because they had a legitimate expectation of privacy in the invaded place, and that the officer’s observation constituted an unreasonable search.

Held: Any search that may have occurred did not violate respondents’ Fourth Amendment rights. The state courts’ analysis of respondents’ expectation of privacy under the rubric of “standing” doctrine was expressly rejected in Rakas v. Illinois, 439 U. S. 128, 140. Rather, to claim Fourth Amendment protection, a defendant must demonstrate that he personally has an expectation of privacy in the place searched, and that his expectation is reasonable. Id., at 143-144, n. 12. The Fourth Amendment protects persons against unreasonable searches of “their persons [and] houses,” and thus indicates that it is a personal right that must be invoked by an individual. But the extent to which the Amendment protects people may depend upon where those people are. While an overnight guest may have a legitimate expectation of privacy in someone else’s home, see Minnesota v. Olson, 495 U. S. 91, 98-99, one who is merely present with the consent of the householder may not, see Jones v. United States, 362 U. S. 257, 259. And an expecta-

tion of privacy in commercial property is different from, and less than, a similar expectation in a home. New York v. Burger, 482 U. S. 691, 700. Here, the purely commercial nature of the transaction, the relatively short period of time that respondents were on the premises, and the lack of any previous connection between them and the householder all lead to the conclusion that their situation is closer to that of one simply permitted on the premises. Any search which may have occurred did not violate their Fourth Amendment rights. Because respondents had no legitimate expectation of privacy, the Court need not decide whether the officer’s observation constituted a “search.” pp.87-91.

Michigan v. Summers, 452 U.S. 692 (1981)

Syllabus

When police officers executing a warrant to search a house for narcotics encountered respondent descending the front steps, they requested his assistance in gaining entry and detained him while they searched the premises. After finding narcotics and ascertaining that respondent owned the house, the police arrested him, searched his person, and found heroin in his coat pocket. Respondent, who was charged with possession of the heroin found on his person, moved to suppress the heroin as the product of an illegal search in violation of the Fourth Amendment. The trial judge granted the motion and quashed the information, and both the Michigan Court of Appeals and the Michigan Supreme Court affirmed.

Held: The initial detention of respondent, which constituted a “seizure” and was assumed to be unsupported by probable cause, did not violate his constitutional right to be secure against an unreasonable seizure of his person. For Fourth Amendment purposes, a warrant to search for contraband founded on probable cause implicitly carries with it the limited authority to detain the occupants of the premises while a proper search is conducted. Because it was lawful to require respondent to reenter and to remain in the house until evidence establishing probable cause to arrest him was found, his arrest and the search incident thereto were constitutionally permissible.

Michigan v. Long, 463 U.S. 1032 (1983)

Syllabus

Two police officers, patrolling in a rural area at night, observed a car traveling erratically and at excessive speed. When the car swerved into a ditch, the officers stopped to investigate and were met by respondent, the only occupant of the car, at the rear of the car. Respondent, who “appeared to be under the influence of something,” did not respond to initial requests to produce his license and registration, and when he began walking toward the open door of the car, apparently to obtain the registration, the officers followed him and saw a hunting knife on the floorboard of the driver’s side of the car. The officers then stopped respondent and subjected him to a patdown search, which revealed no weapons. One of the officers shined his flashlight into the car, saw something protruding from under the armrest on the front seat, and, upon lifting the armrest, saw an open pouch that contained what appeared to be marihuana. Respondent was then arrested for possession of marihuana. A further search of the car’s interior revealed no more contraband, but the officers decided to impound the vehicle, and more marihuana was found in the trunk. The Michigan state trial court denied respondent’s motion to suppress the marihuana taken from both the car’s interior and its trunk, and he was convicted of possession of marihuana. The Michigan Court of Appeals affirmed, holding that the search of the passenger compartment was valid as a protective search under Terry v. Ohio,392 U. S. 1, and that the search of the trunk was valid as an inventory search under South Dakota v. Opperman, 428 U. S. 364. However, the Michigan Supreme Court reversed, holding that Terry did not justify the passenger compartment search, and that the marihuana found in the trunk was the “fruit” of the illegal search of the car’s interior.

Held:

1. This Court does not lack jurisdiction to decide the case on the asserted ground that the decision below rests on an adequate and independent state ground. Because of respect for the independence of state courts and the need to avoid rendering advisory opinions, this Court, in determining whether state court references to state law constitute adequate and independent state grounds, will no longer look beyond the opinion under review, or require state courts to reconsider cases to clarify the grounds of their decisions. Accordingly, when a state court decision fairly appears to rest primarily on federal law, or to be interwoven 

Page 463 U. S. 1033

with federal law, and when the adequacy and independence of any possible state law ground is not clear from the face of the opinion, this Court will accept as the most reasonable explanation that the state court decided the case the way it did because it believed that federal law required it to do so. If the state court decision indicates clearly and expressly that it is alternatively based on bona fide separate, adequate, and independent state grounds, this Court will not undertake to review the decision. In this case, apart from two citations to the State Constitution, the court below relied exclusively on its understanding of Terry and other federal cases. Even if it is accepted that the Michigan Constitution has been interpreted to provide independent protection for certain rights also secured under the Fourth Amendment, it fairly appears that the Michigan Supreme Court rested its decision primarily on federal law. Pp.  463 U. S. 1037-1044.

2. The protective search of the passenger compartment of respondent’s car was reasonable under the principles articulated in Terry and other decisions of this Court. Although Terry involved the stop and subsequent patdown search for weapons of a person suspected of criminal activity, it did not restrict the preventive search to the person of the detained suspect. Protection of police and others can justify protective searches when police have a reasonable belief that the suspect poses a danger. Roadside encounters between police and suspects are especially hazardous, and danger may arise from the possible presence of weapons in the area surrounding a suspect. Thus, the search of the passenger compartment of an automobile, limited to those areas in which a weapon may be placed or hidden, is permissible if the police officer possesses a reasonable belief based on specific and articulable facts which, taken together with the rational inferences from those facts, reasonably warrant the officer to believe that the suspect is dangerous and the suspect may gain immediate control of weapons. If, while conducting a legitimate Terrysearch of an automobile’s interior, the officer discovers contraband other than weapons, he cannot be required to ignore the contraband, and the Fourth Amendment does not require its suppression in such circumstances. The circumstances of this case justified the officers in their reasonable belief that respondent posed a danger if he were permitted to reenter his vehicle. Nor did they act unreasonably in taking preventive measures to ensure that there were no other weapons within respondent’s immediate grasp before permitting him to reenter his automobile. The fact that respondent was under the officers’ control during the investigative stop does not render unreasonable their belief that he could injure them. Pp.  463 U. S. 1045-1052.

3. Because the Michigan Supreme Court suppressed the marihuana taken from the trunk as a fruit of what it erroneously held was an illegal 

Page 463 U. S. 1034

search of the car’s interior, the case is remanded to enable it to determine whether the trunk search was permissible under Opperman, supra, or other decisions of this Court. P.  463 U. S. 1053.
