FEDERAL COURTS LAW REVIEW - 2003 Fed. Cts. L. Rev. 1
Terrorism, the Border, and the Fourth Amendment By Roberto Iraola(*)
Abstract
Post September 11th public demand for
heightened homeland security quickly and
inevitably runs headfirst into the U.S.
Constitution's Fourth Amendment protections
against unreasonable search and seizure.
According to author Roberto Iraola, that collision
point is no where more evident than at our
national borders. Fourth Amendment
jurisprudence recognizes an exception to the
warrant requirement for routine searches and
seizures at the border. Mr. Iraola's timely article
analyzes the rationale and case law surrounding
this exception. The extensive collection of
current media materials and case law provide an
invaluable resource for any judge or fourth
amendment scholar.
[I.1] Yearly, United States seaports receive 51,000 calls from 7,500 foreign-flag ships (1) and
approximately 6 million cargo containers. (2) On land, 2.2 million rail cars and 11.2 million trucks
enter the country annually, while more than 500 million persons (of which 330 million are non-citizens) are admitted into the United States. (3) It is further estimated that the United States
processes approximately $1.2 trillion worth of trade a year. (4)
[I.2] While none of the nineteen hijackers involved in the planes used in connection with the
September 11 attacks are believed to have entered the United States through Canada or Mexico, (5)
following these attacks, security along the nation's borders was substantially heightened for
terrorists and weapons. (6) Other countries have followed suit. (7)
[I.3] In February 2002, administration officials announced the deployment of 1,600 National
Guard troops to help inspect trucks and cars and perform other duties at some of the 156 ports of
entry along the southwest and northern borders. (8) In April 2002, the Pentagon announced the
establishment of the Northern Command, responsible for defending U.S. airspace and coasts and
also for coordinating military relations with Mexico and Canada. (9) Legislation also was passed in
the Congress affecting border security issues (10) and security accords reached with Canada and
Mexico to improve security along the common borders. (11) In September 2002, the Immigration
and Naturalization Service initiated a new program requiring foreign visitors to be photographed
and fingerprinted at the border. (12)
[I.4] Homeland Security Director Tom Ridge has cautioned that the borders remain vulnerable
to terrorists and that coordination must be improved among the various agencies responsible for
guarding them - the Customs Service, the Coast Guard, the Immigration and Naturalization
Service, and the Border Patrol. (13) In a similar vein, Customs Service Commissioner Robert C.
Bonner has warned that effective border enforcement will require "a combination of good
intelligence, advance arrival information, state-of-the-art inspection technology, strong industry-government partnerships, a well-trained workforce, and sophisticated systems to exchange and
analyze mountains of data." (14)
[I.5] Undoubtedly, the long-term campaign against terrorism will maintain a criminal law
component, (15) which will be part of a broader diplomatic, intelligence, economic and military
effort. (16) In the context of criminal law enforcement, the question arises -- to what extent does the
detention and/or search of persons and goods attempting to enter the United States implicate the
Fourth Amendment?
[I.6] This article generally explores the Fourth Amendment's exception for routine searches and
seizures occurring at the border. (17) It is divided into three parts. First, the article provides an
overview of the requirements of the Fourth Amendment. A discussion of the difference between
routine and non-routine searches and seizures at the border, and the Fourth Amendment standards
governing each, follows. Lastly, the article addresses searches and seizures which occur at the
functional equivalent of the border.
The right of the people to be secure in their persons, houses,
papers, and effects, against unreasonable searches and seizures,
shall not be violated, and no Warrants shall issue, but upon
probable cause, supported by Oath or affirmation, and particularly
describing the place to be searched, and the persons or things to be
seized. (18)
The first clause of the Fourth Amendment proscribes unreasonable searches and seizures; (19) the
second clause addresses the requirements necessary to obtain a warrant. (20)
[II.2] Generally, a search requires a warrant based on probable cause, (21) a level of individualized
suspicion, (22) or an exception to the warrant requirement. (23) One of the exceptions to the warrant
requirement is that found for routine searches and seizures which take place at the international
border, (24) or its functional equivalent. (25)
[II.3] It is well-established that a traveler crossing an international boundary reasonably may be
required "to identify himself as entitled to come in, and his belongings as effects which may be
lawfully brought in." (26) Consequently, "[a]t the border one's expectation of privacy is less than in
the interior and the Fourth Amendment balance between the government's interests and the
traveler's privacy rights is 'struck much more favorably to the Government.'" (27) As a result,
routine searches at the border "are not subject to any requirement of reasonable suspicion,
probable cause, or warrant[.]" (28) Under the Fourth Amendment, border searches are deemed
reasonable because of "the single fact that the person or item in question had entered into our
country from outside." (29)
[II.4] The rationale for the border exception rests on the notion that, as a sovereign state, the
United States "has the right to control what persons or property crosses its international
borders." (30) It has been noted that "[t]he federal government's power over immigration and
foreign commerce is immense, and the nation's border is the primary locus at which that power
must be exercised." (31) Two important governmental interests are advanced by routine searches
and seizures at the border. First, "the sovereign's interest in excluding undesirable outside
influences, such as entrants with communicable diseases, narcotics, or explosives[.]" (32) Secondly,
and "[a]s important is the sovereign's interest in regulating foreign commerce and, in particular, in
regulating and controlling its currency." (33)
[II.5] But what precisely are "routine" border stops and searches? (34) What happens when more
than a routine border stop and search is involved? And what are the factors to consider when
determining whether a search or seizure takes place at the functional equivalent of the border? It
is to a discussion of those questions that we now turn.
[III.1] In general, routine and nonroutine searches are distinguished by the degree and nature of
the intrusiveness involved. (35) In the case of seizures, the test centers on the length of the
detention. (36) Each of these types of searches and seizures are discussed below.
[III.A.1] Routine searches of persons entering the country generally have been found when
such persons have been requested to remove their shoes, (37) roll up their sleeves, (38) lift up their
skirts, (39) remove their coat, (40) or submit to a patdown. (41) Some courts, however, have ruled that a
degree of suspicion is necessary when a person is asked to lift her skirt (42) or to submit to a
patdown. (43)
[III.A.2] Strip searches, body cavity searches, and involuntary x-ray searches, are all
examples of non-routine border searches of persons. (44) Courts have held that the amount of
suspicion needed to justify a strip search is real (45) or reasonable suspicion. (46) Similarly, body
cavity (47) and x-ray searches require reasonable suspicion. (48) One distinguished commentator has
pointed out that the application of the reasonable suspicion standard to body cavity searches does
not change the fact "that body cavity searches are more intrusive than other border searches and
consequently require a stronger justification in terms of the probability that the individual
subjected to the procedure is carrying contraband." (49)
[III.A.3] In general, "[a] search at the border of a traveler's luggage and personal effects is
routine." (50) And while "[i]t is permissible for the authorities to search automobiles, luggage, and
goods entering the country," (51) courts have ruled that drilling into the body of a vehicle (52), or in the
plywood section of the hull of a boat are not routine searches. (53) Generally, for these types of
intrusions, reasonable suspicion of illegal activity is required. (54)
[III.B.1] Non-routine seizures of persons most commonly have arisen in the context of the
detention of drug smugglers who conceal the contraband in their alimentary canal. (55) What level
of suspicion, if any, is required for non-routine seizures?
[III.B.2] In United States v. Montoya de Hernandez, (56) the Supreme Court was confronted
with the question of "what level of suspicion would justify a seizure of an incoming traveler for
purposes other than a routine border search." (57) The defendant in Montoya de Hernandez was
suspected of carrying drugs in her alimentary canal. (58) After rejecting a standard for prolonged
detention based on a "clear indication" of drug smuggling, (59) the Supreme Court ruled "that the
detention of a traveler at the border, beyond the scope of a routine customs search and inspection,
is justified at its inception if customs agents, considering all the facts surrounding the traveler and
her trip, reasonably suspect that the traveler is smuggling contraband in her alimentary canal." (60)
[III.B.3] Once reasonable suspicion exists to detain a traveler, such detention can continue
"for the period of time necessary to either verify or dispel the suspicion." (61) Under the reasonable
suspicion standard, the detention of those suspected of alimentary canal smuggling has been held
lawful for periods ranging from ninety minutes to twenty-four days. (62) As noted by several well-known commentators, "[t]his means that if, as in de Hernandez, the suspect declines to submit to
an x-ray, then the detention on reasonable suspicion may continue until a bowel movement
occurs." (63)
[IV.1] In some instances, "it is not feasible to conduct a search at the actual border." (64) A search
and seizure that does not technically occur at the border may still fall within the border exception,
as long as it takes place at the functional equivalent of the border. (65)
[IV.2] In Almeida-Sanchez v. United States, (66) the Supreme Court noted in dicta that the border
search exception could apply to searches that "take place not only at the border itself, but at its
functional equivalents as well." (67) The Court illustrated this principle with the following two
examples.
[S]earches at an established station near the border, at a point
marking the confluence of two or more roads that extend from the
border, might be functional equivalents of border searches. For
another example, a search of passengers and cargo of an airplane
arriving at a St. Louis airport after a nonstop flight from Mexico
City would clearly be the functional equivalent of a border search. (68)
Almedia-Sanchez concerned a roving patrol on a highway 20 miles from the border. (69) The Court
determined that the search of the automobile in that case did not fall within the functional border
exception and, in the absence of probable cause or consent, violated the Fourth Amendment. (70)
[IV.3] The justification for the functional equivalent component to the border search exception is
that "it is in essence no different than a search conducted at the border; the reason for allowing
such a search to take place other than at the actual physical border is the practical impossibility of
requiring the subject searched to stop at the physical border." (71) The Eleventh Circuit has
described the test for determining whether a search took place at the functional equivalent of the
border as encompassing the following three factors: "[i] reasonable certainty that the border was
crossed (72); [ii] no opportunity for the object of the search to have changed materially since the
crossing (73); and [iii] the search must have occurred at the earliest practicable point after the border
crossing." (74) Other courts have taken similar approaches. (75) Examples of the functional equivalent
of the border include where a ship docks after arriving from foreign waters, (76) an international
airport, (77) or a fixed automobile checkpoint near the border. (78) In all circumstances, "an actual
border crossing must have occurred to justify a search." (79)
[V.1] Homeland Security Director Ridge has indicated that the terrorism threat represents a
"permanent condition" and that Americans are going to have to learn to live with that threat. (80) In
the continuing effort to combat terrorism - from suicide bombers, (81) to biological agents (82) and
dirty bombs (83) - careful scrutiny at the border, (84) and beyond, will be imperative. (85) The border
exception to the Fourth Amendment provides the government with the necessary flexibility to
detain and search persons and goods in its endeavor to protect the mainland and its citizens
against acts of terrorism.
[VI.1] Fourth Amendment jurisprudence recognizes an exception to the warrant requirement for
routine searches and seizures which take place at the border or its functional equivalent. Mr.
Iraola's timely article analyzes the rationale for this exception and the caselaw discussing routine
and non-routine searches. The world has been transformed since September 11 and the resulting
expectation of privacy that Americans share diminished. In light of that transformation, only time
will tell whether even the narrow restrictions on border searches survive.

York, 442 U.S. 319, 325 (1979), and the place to be searched. Coolidge v. New Hampshire, 403
U.S. 443, 471 (1971). In Steagald v. United States, 451 U.S. 204 (1981), the Supreme Court
explained the different interests protected by an arrest warrant and a search warrant as follows:
An arrest warrant is issued by a magistrate upon a showing that probable cause
exists to believe that the subject of the warrant has committed an offense and thus
the warrant primarily serves to protect an individual from an unreasonable seizure.
A search warrant, in contrast, is issued upon a showing of probable cause to
believe that the legitimate object of a search is located in a particular place , and
therefore safeguards an individual's interest in the privacy of his home and
possessions against the unjustified intrusion of the police.

their belongings and effects, all without violating the Fourth Amendment[.]" Id. at 63. Relying in
part on this dicta, the circuit courts that have confronted the issue of whether the border
exception applies to outgoing, as well as incoming travelers and goods, uniformly have ruled that
it does. See United States v. Beras, 183 F.3d 22, 26 (1st Cir. 1999) (traveler); United States v.

exempt outgoing searches from the requirements of a warrant, probable cause, and reasonable
suspicion."). It has been noted, however, that in several of these cases, the courts "emphasized
the narrowness of their holdings" and that "[n]o case has explicitly held that the border search
exception applies identically to searches of persons or property entering and exiting the country,
and without regard to the purpose of the search." United States v. Roberts, 86 F. Supp. 2d 678,
685 (S.D. Tex. 2000).
30. United States v. Cardenas, 9 F.3d 1139, 1147 (5th Cir. 1993). SeeMontoya De Hernandez,
473 U.S. at 537-38 (executive branch has "plenary authority" to engage in routine warrantless
border searches and seizures "in order to regulate the collection of duties and to prevent the
introduction of contraband into this country"); Torres v. Puerto Rico, 442 U.S. 465, 472-73
(1979) (recognizing government's "inherent sovereign authority to protect its territorial
integrity."); Ramsey, 431 U.S. at 616 (government may search mail entering the United States
based on its "longstanding right . . . to protect itself by stopping and examining persons and
property crossing into this country."). See generally, Fung, supra note 24, at 756 ("[C]ourts have
premised the government's broad power to conduct searches and seizures at international borders
on the sovereign's legitimate interest in protecting its borders.").
The government has a fundamental interest in enforcing its
immigration laws through border-zone searches. Immigration laws
are uniquely important because a state is defined by its members
and their agreement to form it. Membership in a specific
community or state is the 'central concept of politics'; the identity
of the members of a community is critical to the political
embodiment of that community.

currency justify the diminished recognition of privacy inherent in crossing into and out of the
borders of the United States."); Berisha, 925 F.2d at 791 (recognizing "the substantial national
interest in regulating the exportation of domestic currency at the border.").
Additionally, 31 U.S.C. § 5317(b) (2000) authorizes warrantless border searches for
purposes of enforcing the currency reporting requirements found in section 5316. In particular,
section 5317(b) states that "a customs officer may stop and search, at the border and without a
search warrant, any vehicle, vessel, aircraft, or other conveyance, any envelope or other container,
and any person entering or departing from the United States." In 1986, Congress removed the
"reasonable cause" requirement from this provision, seeEzeiruaku, 936 F.2d at 139, thereby
authorizing border searches to the full extent permitted by the Constitution. SeeUnited States v.
Benevento, 836 F.2d 60, 68-69 n.1 (2d Cir. 1987), cert. denied, 486 U.S. 1043 (1988).
34. Border officials are given the authority to perform searches at the border by statutes and
regulations. See, e.g., 19 U.S.C. § 482 (2000)(customs official may search persons or vehicle if
reasonable cause to suspect contraband); 19 U.S.C. § 1582 (2000) ("The Secretary of Treasury
may prescribe regulations for the search of persons and baggage . . . and all persons coming into
the United States from foreign countries shall be liable to detention and search by authorized
officers or agents of the Government under such regulations."); 19 C.F.R. § 162.6 (2002)( "[a]ll
persons, baggage, and merchandise arriving in the Customs territory of the United States from

have generally required a higher level of suspicion to justify such a search.") (footnotes omitted).
In United States v. Rivas, 368 F.2d 703 (9th Cir. 1966), the Ninth Circuit adopted a
"clear indication" standard for body cavity searches. The court stated:
An honest 'plain indication' that a search involving an intrusion
beyond the body's surface is justified cannot rest on the mere
chance that the desired evidence may be obtained . . . . There must
exist facts creating a clear indication, or plain suggestion, of the
smuggling. Nor need those facts reach the dignity of nor be the
equivalent of 'probable cause' necessary for an arrest and search at
a place other than a border.
Id. at 710. See alsoDes Jardins, 747 F.2d at 505 (x-ray examinations require "'a clear indication'
that the suspect is carrying contraband in a body cavity[.]"); United States v. Castrillon, 716 F.2d
1279 1280 (9th Cir. 1983). One commentator has noted that "[t]he clear indication standard,
when applied in a border search context, has generally been interpreted to require a greater
showing than reasonable suspicion, but a lesser showing than probable cause to validate the
search." Roland, supra note 35, at 1094 (footnote omitted).
In Montoya de Hernandez, discussed more fully in Section III.B infra, the Supreme
Court rejected the clear indication standard in favor of a reasonable suspicion standard when
addressing the reasonableness of a detention at the border. 473 U.S. at 541. This "more general,
but firm rejection of a third verbal standard" has led some courts to decline to adopt the "'clear
indication' standard in the context of a body cavity search." Ogberaha, 771 F.2d at 658.
Following Montoya de Hernandez, the Ninth Circuit has recognized in dictum that "body-cavity
searches are of course considered nonroutine, and, unlike luggage searches must be supported by
reasonable suspicion." Gonzalez-Rincon, 36 F.3d at 864.

subtle verbal gradations may obscure rather than elucidate the meaning of the provision in
question.").
60. Id. at 541 (footnote omitted). In adopting this standard, the Court in Montoya de Hernandez
explained:
The 'reasonable suspicion' standard has been applied in a number of
contexts and effects a needed balance between private and public
interests when law enforcement officials must make a limited
intrusion on less than probable cause. It thus fits well into the
situations involving alimentary canal smuggling at the border: this
type of smuggling gives no external signs and inspectors will rarely
possess probable cause to arrest or search, yet governmental
interests in stopping smuggling at the border are high indeed.
Under this standard officials at the border must have a
'particularized and objective basis for suspecting the particular
person' of alimentary canal smuggling.

(11th Cir. 1981); United States v. Driscoll, 632 F.2d 737, 739 (9th Cir. 1980). Rejecting the
contention that to establish a valid border search, the government also had to demonstrate that the
craft had left foreign land, the court in Stone observed:
Such an added requirement . . . is tenable neither in law nor logic.
In no case has a border search been invalidated because the object's
departure from foreign soil was not demonstrated. Instead, a legion
of cases have made clear that the propriety of a border search rests
on the 'critical fact' of whether or not a border crossing has
occurred[.]

searches at the final destination of the goods has been sanctioned by the courts. See, e.g., United
States v. Gaviria, 805 F.2d 1108, 1113-14 (2nd Cir. 1986), cert. denied, 481 U.S. 1031 (1987);

F.2d 1057, 1069-70 (5th Cir. 1981), cert. denied, 455 U.S. 991 (1982). As summarized by the
court in Gaviria:
[W]hen goods physically enter the United States at one point, and
are subsequently transferred to another port of entry, then the final
port of entry will be considered the functional equivalent of the
border for the purposes of a customs search, only if: (1) it is the
intended final destination of the goods; (2) the goods, upon arrival,
remain under a customs bond until a final search is undertaken by
Customs; and (3) there is no evidence that anyone has tampered
with the goods while in transit.

most of the cars passing through their checkpoint had recently, or ever, crossed the border.").
Even if a fixed checkpoint does not qualify as the functional equivalent of the border, the
Supreme Court has upheld the use of such checkpoints to stop vehicles and question their
occupants absent any suspicion that illegal aliens are aboard the vehicles. United States v.
Martinez-Fuerte, 428 U.S. 543 (1976). Searches by border patrol agents at checkpoints not
