The district court held that a warrantless search of a fifty-five gallon drum labeled phosphoric acid and in transit to defendants by common carrier violated the Fourth Amendment and suppressed the evidence. The government appeals, arguing that the defendants had no reasonable expectation of privacy in the drum and that the agents had consent to perform the search. We find these arguments without merit and affirm.
I.
One afternoon in February of 1991, employees at Southwest Motor Transport’s terminal in Brownsville became suspicious of two fifty-five gallon drums that had been delivered for shipment to Corpus Christi. The drums were labeled as phosphoric acid, but the employees thought them too light to contain acid and noticed that they did not make sloshing noises when moved. They also lacked the hazardous materials labels normally required for such freight. The foreman, Joe Gracia, suspected that the drums contained contraband. He called Forest Kaupert, a senior vice-president at SMT, who told him to call Customs and have them come over and investigate.
Gracia called Customs, and two agents arrived shortly thereafter. Gracia showed the agents the shipping order for the drums, reflecting their contents as phosphoric acid. However, the weight listed on the order was less than half the expected weight of drums of liquid. The order showed that Roland Martin of Brownsville was the consignor and consignee for the drums. The agents’ drug sniffing dog alerted to the drums. Without asking Gra *773 cia whether they could open the drums, and without obtaining a warrant, they opened one of the drums and discovered marijuana inside. They then decided to make a controlled delivery, resealed the drum, and sent both drums to the SMT terminal in Corpus Christi.
As it turned out, defendants Santos Villarreal and Sergio Gonzalez were the intended recipients of the drums. Roland Martin was a fictitious name used to ship the drums so that no one could be connected to the marijuana in case anything went wrong. Villarreal did not speak English so he asked a woman named Sylvia Villarreal at South Texas Recycling to call SMT and find out how much the freight charges would be and how arrangements could be made to pick up the drums. He told her that the drums were not his but belonged to an individual named Roland Martin. She called SMT and obtained the information Villarreal needed.
Villarreal and Gonzales then paid two employees of South Texas Recycling named Torres and Guzman to pick up the drums for them and gave them the receipt for the drums. Torres and Guzman then drove a flatbed truck to the SMT terminal, and Villarreal and Gonzales followed in Villarreal’s red pick-up truck. Torres and Gua-rnan obtained the drums from SMT and loaded them onto the flatbed. They returned to South Texas Recycling, again followed by Villarreal and Gonzales in the pick-up. Torres and Guzman then loaded the drums from the flatbed into the pickup. Gonzales drove the pick-up away, and Villarreal left in Sylvia Villarreal’s car. Both men were arrested shortly thereafter, and the drums were seized from the pickup at the Spinning Wheel Bar where Gonzales had parked it.
Villarreal and Gonzales were charged with possessing and conspiring to possess more than 100 kilograms of marijuana with intent to distribute it in violation of 21 U.S.C. §§ 841(a)(1), 841(b)(1)(B) and 846. At a pre-trial suppression hearing, defendants argued that the warrantless search of the drum at the SMT terminal in Brownsville violated their Fourth Amendment rights. The government contended that the defendants had no reasonable expectation of privacy in the drums and that the customs agents had in any event obtained consent to search them. The district court rejected the government’s arguments and granted the defendants’ motion to suppress. The government appeals.
II.
The Fourth Amendment protects individuals from unreasonable searches and seizures that intrude on reasonable expectations of privacy. Warrantless searches are presumptively unreasonable.
Horton v. California,
Individuals do not surrender their expectations of privacy in closed containers
*774
when they send them by mail or common carrier. The Supreme Court has long recognized that “[l]etters and other sealed packages are in the general class of effects in which the public at large has a legitimate expectation of privacy.”
United States v. Jacobsen,
The drum opened by the customs agents in this case was a closed container sent by common carrier in which the sender and addressee had a reasonable expectation of privacy. Despite the fact that we do not usually expect personal effects to be found in a fifty-five gallon drum, such drums are not excluded from Fourth Amendment protection. We are unwilling to draw distinctions based on the relative degrees of privacy in different containers and thereby introduce further complexity to a warrant requirement that is already riddled with exceptions.
See California v. Acevedo,
— U.S. —,
Although the consignee of the drums was technically a fictitious person named Roland Martin, this court has made clear that individuals may assert a reasonable expectation of privacy in packages addressed to them under fictitious names.
See Richards,
The government has not argued, and we do not find, that the warrantless search of the drums was justified as an administrative or regulatory search. The Court has explained that “legislative schemes authorizing warrantless administrative searches of commercial property do not necessarily violate the Fourth Amendment.”
Donovan v. Dewey,
Nor is this a case where the searching officers had reason to believe that the container contained a “dangerous instrumentality” such that opening the container was imperative for safety reasons.
See United States v. Chadwick,
The government argues that defendants abandoned any expectation of privacy they might otherwise have had by disassociating themselves from the drums. It observes that the drums were shipped under an assumed name, that Villarreal told Sylvia Villarreal that the drums actually belonged to Roland Martin, and that the defendants did not pick them up themselves but hired others to do so. It relies on our decision in
United States v. Boruff,
This case is distinguishable from Boruff and the other cases in which courts have found that defendants have no reasonable expectation of privacy by virtue of their disassociation from the object of the search. Villarreal and Gonzales never denied their possessory interest in the drums. They acted through intermediaries and used fictitious names in an effort to escape detection, but they consistently acted as if they were the ones who were to receive the drums. They retained possession of the receipt for the drums, which was the only indication of ownership available. They gave the receipt to Torres and Guzman so that these two could pick up the drums on their behalf, but they took possession of the drums immediately thereafter. Ultimately, Gonzales drove off with the drums in Villarreal’s pick-up truck. It can hardly be said that they disassociated themselves from the object of the search.
The government also urges that the drums are in the special category of containers which “by their very nature cannot support any reasonable expectation of privacy because their contents can be inferred from their outward appearance.”
Arkansas v. Sanders,
The government argues that the contents of the drums could be inferred because the drums were labeled as phosphoric acid and the shipping order indicated that they contained phosphoric acid. Thus the customs agents violated no reasonable expectation of privacy when they opened one of the drums and found marijuana within. In the government’s view, the defendants never had an expectation of privacy because the drums literally proclaimed their contents for all to see.
We are not persuaded. The fact that the exterior of a container purports to reveal some information about its contents does not necessarily mean that its owner has no reasonable expectation that those contents will remain free from inspection by others. Stated another way, a label on a container is not an invitation to search it. If the government seeks to learn more than the label reveals by opening the container, it generally must obtain a search warrant.
See Walter v. United States,
If, as some courts have suggested, the rule the government seeks to invoke is properly characterized as a “plain view” exception to the warrant requirement,
see Robbins,
The government also contends that the customs agents obtained consent to search the drums. Putting aside the question of whether a common carrier has the authority to consent to a search on behalf of the consignor and consignee of a package
4
, the district court properly con-
*777
eluded that no consent was given here. “Where the validity of a search rests on consent, the State has the burden of proving that the necessary consent was obtained and that it was freely and voluntarily given, a burden that is not satisfied by showing a mere submission to a claim of lawful authority.”
Florida v. Royer,
In short, we have found no justification for a warrantless search of the drums. The government clearly had probable cause, but “ ‘no amount of probable cause can justify a warrantless search or seizure absent exigent circumstances.’ ”
Horton,
AFFIRMED.
Notes
. A notable exception exists for mail, packages, or other containers that are entering the United States from abroad.
See United States v. Ramsey,
. While both
Sanders
and
Robbins
have been overruled, the logic of the
Sanders
footnote has survived.
See United States v. Donnes,
. We do not consider here whether an individual could have a reasonable expectation of privacy in a container when he has plainly communicated its incriminating character to the public— if, for example, the drums in this case were labeled as marijuana.
. At least one court has found a Fourth Amendment violation despite the fact that a common carrier directed police officers to search a container that was in its custody.
