United States v. Place
The Court ruled that police may briefly detain luggage they reasonably suspect contains drugs, without probable cause, and that having a trained dog sniff luggage in a public place is not a Fourth Amendment search at all.
But the Court also held that the 90-minute detention of this traveler's suitcases went too far, turning an acceptable brief stop into an unreasonable seizure, so the cocaine found inside had to be thrown out as evidence.
“the canine sniff is sui generis.”
The majority's explanation for why a trained dog's sniff of luggage is unlike an ordinary search.
How it got here: A federal trial court denied Place's motion to suppress the cocaine; the Second Circuit reversed, finding the luggage detention too long; the government sought Supreme Court review.
The Case in Depth
What happened
Raymond Place aroused suspicion buying a one-way ticket in Miami; agents there found his address information didn't check out. When he landed in New York, DEA agents approached him, and after he refused to let them search his bags, they took the suitcases to another airport for a dog sniff. The dog reacted to one bag, and after a weekend delay, agents got a warrant and found over a kilogram of cocaine inside.
The question before the Court
Could federal agents lawfully hold onto a traveler's suitcases for 90 minutes to have a drug-sniffing dog check them, based only on reasonable suspicion rather than probable cause?
The Court's answer
No — the 90-minute detention of Place's suitcases was too long to qualify as a brief, reasonable-suspicion-based stop under the Terry framework, so the cocaine agents found had to be suppressed. The Court did say that briefly detaining luggage on reasonable suspicion (short of probable cause) can be lawful, and that a trained dog sniffing the outside of luggage isn't a "search" requiring its own justification.
But applying those rules to the facts here, the agents took too long — 90 minutes, when they had advance notice of Place's arrival and could have arranged things faster — and never told him where his bags were going or how to get them back. That combination made this particular seizure unreasonable, even though a shorter, better-explained detention might have passed muster.

Why it matters
Airport travelers can now be briefly stopped and have their bags held for a quick dog sniff on reasonable suspicion alone, without officers first getting a warrant or having probable cause. But the ruling also limits how long and how disruptively police can hold a traveler's belongings, giving travelers a concrete benchmark — roughly the length of a brief stop, not 90 minutes — for challenging prolonged luggage seizures in court.
What changes now
Because the seizure of the luggage was unreasonable, the cocaine found inside could not be used as evidence, and Place's conviction was reversed by the Second Circuit and that result is affirmed here. This is a final merits decision; it does not set a fixed outer time limit for how long luggage may be held, leaving future cases to work out exactly how much delay is too much on their own facts.
What this does not decide
The Court did not set a fixed maximum time limit for how long police can detain luggage on reasonable suspicion, and several justices objected that the Court did not need to decide — and should not have decided — whether a dog sniff is a "search," since that issue was not raised below or briefed by the parties.
Concurrences and dissents
Concurrence — Justice Brennan
“In short, it represents a radical departure from settled Fourth Amendment principles.”Brennan's objection to letting police seize luggage on reasonable suspicion rather than probable cause.
Justice Brennan would have affirmed simply because the seizure was too long, without reaching the broader questions the majority decided. He argued the majority's extension of Terry to allow independent seizures of property on mere reasonable suspicion was an unwarranted and radical expansion of that narrow exception, since seizures of property have always required probable cause. He also thought the Court should not have addressed whether dog sniffs are searches, since that issue wasn't briefed or argued.
Concurrence — Justice Blackmun
Justice Blackmun agreed the seizure here was too intrusive to fit within Terry, but worried the majority's broader discussion was turning Terry into a general rule that any seizure is fine as long as it's reasonable, undermining the normal probable-cause requirement. He also thought it was unwise for the Court to resolve whether dog sniffs are searches, since neither party had raised or argued that question and other cases raising it were pending.
How the Court got there
The legal reasoning, step by step
- The Court extended the framework from Terry v. Ohio — which lets police briefly stop and question a person based on reasonable, articulable suspicion rather than full probable cause — to cover brief seizures of a suspect's personal property as well as the person.
- Applying a balancing test, the Court weighed the government's strong interest in intercepting drug traffickers at airports against the intrusion on a traveler's possessory and liberty interests, and concluded that a brief, properly limited detention of luggage on reasonable suspicion can be reasonable even without probable cause.
- The Court separately addressed whether having a trained narcotics dog sniff the outside of luggage counts as a 'search' requiring its own justification. Because a dog sniff does not require opening the bag and reveals only the presence or absence of contraband, the Court held it discloses so little that it is not a search under the Fourth Amendment at all.
- Turning to the specific detention here, the Court held that a seizure of luggage from a traveler's immediate possession must be judged by the same limits that apply to a Terry stop of a person, since holding the bags effectively restrains the traveler's freedom to continue on with his trip.
- Measured against that standard, the 90-minute detention of Place's suitcases — especially given that agents had advance notice of his arrival and could have arranged the dog sniff more quickly — exceeded what a brief investigative detention on reasonable suspicion can justify.
- The agents also failed to tell Place where his bags were going, how long he might be without them, or how he could get them back, which the Court treated as making the intrusion even less justifiable.
