 2 CHÁVEZ, Justice.

 3   {1}   Defendant-Respondent Aide Sanchez (Sanchez) was at the Santa Teresa, New

 4 Mexico port of entry, an international border crossing, attempting to enter the United

 5 States from Mexico, when Border Patrol agents seized marijuana from her van. In

 6 State v. Cardenas-Alvarez, 2001-NMSC-017, ¶ 1, 130 N.M. 386, 25 P.3d 225, we

 7 held that “the New Mexico Constitution and laws apply to evidence seized by federal

 8 agents at a border patrol checkpoint [located] sixty miles within the State of New

 9 Mexico [(an interior fixed checkpoint)] when that evidence is proffered in state

10 court.” We also held that Article II, Section 10 of the New Mexico Constitution

11 “demands that after a Border Patrol agent has asked about a motorist’s citizenship and

12 immigration status, and has reviewed the motorist’s documents, any further detention

13 requires reasonable suspicion of criminal activity.” Cardenas-Alvarez, 2001-NMSC-

14 017, ¶¶ 12, 20.

15   {2}   Sanchez successfully moved to suppress the evidence seized from her van,

16 arguing that (1) Cardenas-Alvarez applies at the international border, and (2) seizure

17 of the marijuana violated the New Mexico Constitution because the Border Patrol

18 agents did not have a reasonable suspicion of criminal activity to continue to detain

19 her once they had established her citizenship and immigration status. We hold that
 1 Article II, Section 10 does not afford greater protections at an international border

 2 checkpoint because unlike motorists who are stopped at interior border checkpoints,

 3 all motorists stopped at international fixed checkpoints are known to be international

 4 travelers who are not entitled to the heightened privacy expectations enjoyed by

 5 domestic travelers. We therefore reverse the district court’s order suppressing the

 6 evidence in this case.

 7 BACKGROUND

 8   {3}   On January 2, 2012, United States Customs and Border Protection Officer

 9 Erica Pedroza (Pedroza) was working as the primary officer at the Santa Teresa Port

10 of Entry, an international border checkpoint. Primary officers are the first customs

11 agents to speak with a motorist seeking to cross an international border. They check

12 motorists’ citizenship documentation and inspect their vehicles for contraband.

13 Primary officers usually have, at most, 30 seconds to decide between releasing a

14 motorist or referring the motorist to a secondary area for further inspection of the

15 vehicle. Further inspections arise for various reasons, including documentation

16 deficiencies such as the lack of a passport, the presence of agricultural products, and

17 evidence that vehicles have been tampered with.

18   {4}   Pedroza testified that while she was working, she encountered Sanchez driving



                                              2
 1 a van. According to Pedroza, Sanchez claimed that she had spent the weekend in

 2 Ciudad Juárez, Mexico and was driving back to Denver, Colorado. Pedroza also

 3 stated that Sanchez produced valid documentation of her legal status as a permanent

 4 resident. However, Pedroza was unable to inspect the van to her satisfaction because

 5 of the presence of a large dog within the van. Consequently, Pedroza referred

 6 Sanchez to a secondary area to have the vehicle inspected, even though Pedroza did

 7 not suspect any criminal activity.

 8   {5}   Customs and Border Protection Officer Monica Pantoja (Pantoja) testified that

 9 she performed a seven-point inspection of Sanchez’s van, which is an inspection of

10 the whole vehicle. As part of this inspection, a drug-sniffing canine located

11 marijuana within Sanchez’s van.

12   {6}   Sanchez was indicted for distribution of marijuana in violation of NMSA 1978,

13 Section 30-31-22(A)(1)(a) (2011) and conspiracy to commit distribution of marijuana

14 in violation of NMSA 1978, Section 30-28-2 (1979). Sanchez filed a motion to

15 suppress the evidence, arguing that under Cardenas-Alvarez, Pedroza lacked the

16 reasonable suspicion of criminal activity required by the New Mexico Constitution

17 to prolong her detention. In Cardenas-Alvarez we held that Article II, Section 10

18 applies to evidence seized at an interior fixed checkpoint “sixty miles within the State



                                              3
 1 of New Mexico when that evidence is proffered in state court.” 2001-NMSC-017,

 2 ¶ 1. Under Cardenas-Alvarez, in the context of an interior fixed checkpoint, Article

 3 II, Section 10 “demands that after a Border Patrol agent has asked about a motorist’s

 4 citizenship and immigration status, and has reviewed the motorist’s documents, any

 5 further    detention   requires   reasonable    suspicion    of   criminal   activity.”

 6 2001-NMSC-017, ¶ 20. The district court granted Sanchez’s motion to suppress,

 7 finding that Pedroza’s referral of Sanchez for a secondary inspection of the van was

 8 not supported by reasonable suspicion of criminal activity. The district court

 9 excluded “all evidence obtained and seized from [Sanchez] and her vehicle, following

10 the referral of [Sanchez] for a secondary inspection.”

11   {7}   The Court of Appeals affirmed the district court, holding that Cardenas-

12 Alvarez applies, irrespective of the location of the checkpoint. State v. Sanchez, No.

13 32,994, mem. op. ¶¶ 1-3, 8 (N.M. Ct. App. Nov. 6, 2013) (non-precedential). The

14 Court of Appeals then concluded that “the facts relied upon by the State neither

15 establish that issues of residence or citizenship were unresolved when [Sanchez] was

16 sent to the secondary inspection area nor that there was any basis for a reasonable

17 suspicion of wrongdoing at that time.” Id. ¶ 6.

18   {8}   We granted the State’s petition for writ of certiorari, State v. Sanchez, 2014-



                                              4
 1 NMCERT-002, to address two issues:

 2               1) Whether the protections of Article II, Section 10 of the New
 3         Mexico Constitution extend to the international border, and, if so,
 4         whether referral of [Sanchez] to a secondary area for continuation of
 5         routine questioning requires individualized suspicion[, and]

 6              2) Whether the application of the interstitial approach in
 7         Cardenas-Alvarez should be revisited.

 8 We decline to interpret Article II, Section 10 as requiring individualized reasonable

 9 suspicion of criminal activity for prolonging detentions at an international border

10 checkpoint. We also decline to revisit the approach taken in Cardenas-Alvarez,

11 because Cardenas-Alvarez is not implicated in this case.

12 DISCUSSION

13   {9}   All of the issues presented in this case are reviewed de novo. “Whether the

14 exclusionary rule under Article II, Section 10 . . . applies to the use of evidence in a

15 New Mexico state court proceeding when that evidence resulted from a search

16 conducted by federal border-patrol agents is a threshold constitutional issue that is

17 subject to de novo review.” State v. Snyder, 1998-NMCA-166, ¶ 6, 126 N.M. 168,

18 967 P.2d 843. If a constitutional provision applies, claims arising under it are also

19 reviewed de novo. State v. Brown, 2006-NMSC-023, ¶ 8, 139 N.M. 466, 134 P.3d

20 753; see also Cardenas-Alvarez, 2001-NMSC-017, ¶ 6 (“The constitutionality of a



                                              5
 1 search or seizure is a mixed question of law and fact and demands de novo review.”).

 2   {10}   In Cardenas-Alvarez, we held that the New Mexico Constitution applies to

 3 evidence seized by federal agents at an interior fixed checkpoint when the State seeks

 4 to introduce the evidence in state court criminal proceedings. 2001-NMSC-017, ¶

 5 20. The question remains whether the greater protections that exist at an interior

 6 fixed checkpoint also exist at the international border checkpoint. To answer this

 7 question, we apply the interstitial approach announced in State v. Gomez,

 8 1997-NMSC-006, ¶¶ 19-22, 122 N.M. 777, 932 P.2d 1.

 9   {11}   Under the interstitial approach,

10          the court asks first whether the right being asserted is protected under
11          the federal constitution. If it is, then the state constitutional claim is not
12          reached. If it is not, then the state constitution is examined. A state
13          court adopting this approach may diverge from federal precedent for
14          three reasons: a flawed federal analysis, structural differences between
15          state and federal government, or distinctive state characteristics.

16 Id. ¶ 19 (citations omitted).

17   {12}   The Fourth Amendment of the United States Constitution provides that “[t]he

18 right of the people to be secure in their persons, houses, papers, and effects, against

19 unreasonable searches and seizures, shall not be violated, and no Warrants shall

20 issue, but upon probable cause . . . .” (Emphasis added.) Article II, Section 10 of the

21 New Mexico Constitution provides that “[t]he people shall be secure in their persons,


                                                  6
 1 papers, homes and effects, from unreasonable searches and seizures . . . .” Article II,

 2 Section 10 parallels the federal Fourth Amendment and embodies “the fundamental

 3 notion that every person in this state is entitled to be free from unwarranted

 4 governmental intrusions.” State v. Gutierrez, 1993-NMSC-062, ¶ 46, 116 N.M. 431,

 5 863 P.2d 1052 (emphasis added).

 6 I.       The United States Constitution was not violated

 7   {13}   The events in this case occurred at an international border checkpoint, not at

 8 an interior fixed checkpoint. “This is an important distinction as a citizen’s Fourth

 9 Amendment rights at a checkpoint located on the border . . . are significantly less than

10 inside the border.” United States v. Rascon-Ortiz, 994 F.2d 749, 752 n.4 (10th Cir.

11 1993). The federal government’s “interest in preventing the entry of unwanted

12 persons and effects is at its zenith at the international border.” United States v.

13 Flores-Montano, 541 U.S. 149, 152 (2004). Therefore, “the Fourth Amendment’s

14 balance of reasonableness is qualitatively different at the international border than

15 in the interior.” United States v. Montoya de Hernandez, 473 U.S. 531, 538 (1985)

16 (emphasis added).

17   {14}   Customs officers are afforded “great latitude in conducting a search at an

18 international border crossing,” Klein v. United States, 472 F.2d 847, 849 (9th Cir.



                                               7
 1 1973), and “may conduct routine searches of persons and effects crossing the border

 2 even in the absence of individualized suspicion.” United States v. Ezeiruaku, 936

 3 F.2d 136, 140 (3d Cir. 1991); see also Montoya de Hernandez, 473 U.S. at 538

 4 (“Routine searches of the persons and effects of entrants are not subject to any

 5 requirement of reasonable suspicion, probable cause, or warrant . . . .”). During these

 6 routine searches, “[t]he primary inspector’s job is to make a preliminary

 7 determination [of] whether an entrant . . . should be allowed beyond the customs

 8 line.” United States v. Salas-Camacho, 859 F.2d 788, 791 (9th Cir. 1988). “The

 9 secondary inspector is called upon to act when a vehicle is referred for additional

10 inspection” and is responsible for “conduct[ing] a more searching examination.” Id.

11 “Referral to a secondary checkpoint . . . is considered to be routine border inspection

12 procedure.” United States v. Ledezma-Hernandez, 729 F.2d 310, 313 (5th Cir. 1984).

13 Thus, suspicion of illicit activities is not required to refer a motorist from a primary

14 to a secondary area. See id. Routine searches include “patdowns, frisks, luggage

15 searches, and automobile searches.” United States v. Whitted, 541 F.3d 480, 485 (3d

16 Cir. 2008). These types of searches conducted at an international border checkpoint

17 “have been considered to be ‘reasonable’ by the single fact that the person or item in

18 question had entered into our country from outside.” United States v. Ramsey, 431



                                              8
 1 U.S. 606, 619 (1977).

 2   {15}   “The border search doctrine is also applicable to stops and searches conducted

 3 at the ‘functional equivalent’ of the border, i.e., the first point at which an entrant may

 4 practically be detained.” United States v. Cardenas, 9 F.3d 1139, 1147 (5th Cir.

 5 1993); see also Almeida-Sanchez v. United States, 413 U.S. 266, 272 (1973).

 6 Searches at the functional equivalents of borders are “those searches that, although

 7 not conducted at the actual physical border, take place after a border crossing at the

 8 first practicable detention point.” United States v. Garcia, 672 F.2d 1349, 1365 (11th

 9 Cir. 1982). “Such searches are truly border searches because their sole justification

10 is the fact that the border has been crossed.” Id. For example, “a search of the

11 passengers and cargo of an airplane arriving at a St. Louis airport after a nonstop

12 flight from Mexico City would clearly be the functional equivalent of a border

13 search.” Almeida-Sanchez, 413 U.S. at 273.

14   {16}   However, there is another federal doctrine concerning “the constitutionality of

15 vehicle stops conducted within U.S. borders.” Garcia, 672 F.2d at 1359 (emphasis

16 added); see United States v. Martinez-Fuerte, 428 U.S. 543 (1976). These cases “did

17 not apply the functional-equivalent theory,” Garcia, 672 F.2d at 1359, because “the

18 distance of the Border Patrol checkpoints from the Mexican border . . . dissuaded the



                                                9
 1 [United States Supreme] Court from applying the border-search rationale.” Id. at

 2 1360 n.14. This doctrine permits “brief warrantless stops of vehicles at permanent

 3 checkpoints absent any suspicion” of illicit activity. Id. at 1359. We will refer to the

 4 line of cases supporting stops within the United States border as the federal “interior

 5 fixed-checkpoint doctrine.”

 6   {17}   The interior fixed-checkpoint doctrine considers “the formidable law

 7 enforcement problems of the Border Patrol in attempting to control the flow of illegal

 8 aliens into this country, and balance[s] this governmental interest against the degree

 9 of interference with individuals’ fourth amendment rights caused by the stop or

10 search procedure at issue in each case.” Garcia, 672 F.2d at 1359-60 (internal

11 quotation marks and citation omitted).

12   {18}   Under the interior fixed-checkpoint doctrine,

13          [a] detention at a border checkpoint is a seizure under the Fourth
14          Amendment. However, because the public has a substantial interest in
15          protecting the integrity of our national borders, and the intrusion upon
16          one’s right to privacy and personal security by a routine border
17          inspection is minimal, a border patrol agent may briefly detain and
18          question an individual without any individualized suspicion . . . . The
19          Fourth Amendment protects an individual’s liberty at a border
20          checkpoint by limiting the scope of the detention.

21 Rascon-Ortiz, 994 F.2d at 752 (footnote and citations omitted). As part of a routine

22 interior fixed-checkpoint stop, “border patrol agents may direct motorists from the


                                              10
 1 primary inspection area to secondary without individualized suspicion and have wide

 2 discretion in selecting the motorists to be diverted.” Id. (internal quotation marks and

 3 citation omitted). “Any further detention must be based on consent or probable

 4 cause.” Martinez-Fuerte, 428 U.S. at 567 (alterations and internal quotation marks

 5 omitted) (quoting United States v. Brignoni-Ponce, 422 U.S. 873, 882 (1975)).

 6   {19}   Routine interior fixed-checkpoint stops generally involve “questions

 7 concerning the motorist’s citizenship or immigration status, and a request for

 8 documentation.” Rascon-Ortiz, 994 F.2d at 752. “A cursory visual inspection of the

 9 vehicle is also routine, and a few brief questions concerning such things as vehicle

10 ownership, cargo, destination, and travel plans may be appropriate if reasonably

11 related to the agent’s duty to prevent” illegal immigration and the smuggling of

12 contraband. Id. (citation omitted). However, “neither the vehicle nor its occupants”

13 can be searched as part of a “routine inquiry,” and the “visual inspection of the

14 vehicle is limited to what can be seen without a search.” United States v. Ludlow,

15 992 F.2d 260, 264 (10th Cir. 1993). Thus, the routine stops permitted under the

16 interior fixed-checkpoint doctrine are less intrusive upon travelers’ privacy than the

17 routine searches permitted at an international border checkpoint under the border

18 search doctrine. Compare Whitted, 541 F.3d at 484-85 (discussing the scope of



                                              11
 1 routine searches allowed under the border search doctrine), with Ludlow, 992 F.2d at

 2 263-64 (discussing the scope of routine inquiries allowed under the interior

 3 fixed-checkpoint doctrine); see also Rascon-Ortiz, 994 F.2d at 752 n.4 (“[A] citizen’s

 4 Fourth Amendment rights at a checkpoint located on the border, or its functional

 5 equivalent, are significantly less than inside the border.”).

 6   {20}   Because the search in this case occurred at an international border checkpoint,

 7 we analyze the constitutionality of the search under the border search doctrine and

 8 conclude that Sanchez’s referral to a secondary area was a permissible part of a

 9 routine border search. See Klein, 472 F.2d at 849. Because the canine drug-sniff was

10 performed during the course of this routine search, the drug-sniff was also

11 permissible under federal law. See United States v. Kelly, 302 F.3d 291, 294-95 (5th

12 Cir. 2002) (holding that the use of a trained canine to sniff a pedestrian entering the

13 United States is a permissible part of a routine border search, even without a showing

14 of individualized suspicion of illicit activity).

15   {21}   The parties agree that the federal constitution does not confer upon Sanchez the

16 right to be free of prolonged detention, even if the detaining officer lacked reasonable

17 suspicion of illicit activities. Because there was no federal constitutional violation,

18 we proceed to the state constitutional claim. See Gomez, 1997-NMSC-006, ¶ 19.



                                               12
 1 II.      There are no reasons to diverge from the federal border search doctrine

 2   {22}   Under New Mexico law, we “may diverge from federal precedent for three

 3 reasons: a flawed federal analysis, structural differences between state and federal

 4 government, or distinctive state characteristics”; this is also known as the interstitial

 5 approach. See id. We do not detect a flaw in the federal analysis concerning the

 6 border search doctrine. A rule that more robustly curbs the ability of law enforcement

 7 to conduct border searches “would frustrate the customary examinations conducted

 8 by customs officials as normal incidents of the meeting of their responsibilities.”

 9 Blefare v. United States, 362 F.2d 870, 884 (9th Cir. 1966). The border search

10 doctrine thus acknowledges the “exigencies present and the vital national interest

11 demanding the regulation of who and what traverse our borders.” Blefare, 362 F.2d

12 at 884.

13   {23}   As in Cardenas-Alvarez, we also conclude that there are no structural

14 differences between state and federal governments so as to require a departure from

15 federal precedent. 2001-NMSC-017, ¶ 14. Moreover, Sanchez does not argue that

16 structural differences should warrant a departure. She contends instead that “New

17 Mexico law provides several distinctive characteristics that require departure.”

18   {24}   Sanchez contends that New Mexico has distinctively provided heightened



                                              13
 1 protections from searches and seizures “in both the automobile context and in the

 2 border context.” She urges us to extend Cardenas-Alvarez to hold that Pedroza

 3 violated Article II, Section 10 when she referred Sanchez to a secondary area of an

 4 international border checkpoint to complete the inspection of Sanchez’s van.

 5 Cardenas-Alvarez relied upon “the extra layer of protection that New Mexico offers

 6 its motorists” to justify heightened search and seizure protections at interior fixed

 7 checkpoints. Id. ¶¶ 1, 16. Thus, Sanchez would have us hold that the scope of

 8 travelers’ rights at international border checkpoints are identical to the scope of rights

 9 at interior fixed checkpoints.

10   {25}   Cardenas-Alvarez concerned stops at interior fixed checkpoints, and it

11 accordingly analyzed the facts of the case under the interior fixed-checkpoint

12 doctrine. Id. ¶¶ 1-2, 16. New Mexico has rejected the “notion that an individual

13 lowers his [or her] expectation of privacy when he [or she] enters an automobile, and

14 elected instead to provide motorists with a ‘layer of protection’ from unreasonable

15 searches and seizures that is unavailable at the federal level.” Id. ¶ 15 (citation

16 omitted). “Therefore, in New Mexico, we . . . proscribe the prolongation of [an

17 interior fixed-]checkpoint stop once questions regarding citizenship and immigration

18 status have been answered, unless the officer conducting the stop reasonably suspects



                                               14
 1 the defendant of criminal activity.” Id. ¶ 16. In contrast, under the federal interior

 2 fixed-checkpoint doctrine, “questions regarding travel plans and the referral of a

 3 defendant from primary to secondary part of a routine border checkpoint stop . . .

 4 require[] no suspicion of criminal activity . . . .” Id.

 5   {26}   While Cardenas-Alvarez departed from the federal interior fixed-checkpoint

 6 doctrine, it did not analyze the federal border search doctrine. See generally id. “The

 7 general rule is that cases are not authority for propositions not considered.”

 8 Fernandez v. Farmers Ins. Co. of Arizona, 1993-NMSC-035, ¶ 15, 115 N.M. 622,

 9 857 P.2d 22 (internal quotation marks and citations omitted).           Consequently,

10 Cardenas-Alvarez cannot be read as modifying the federal border search doctrine,

11 which is implicated by the facts of this case. We therefore determine whether the

12 extra layer of protection afforded to New Mexico motorists mandates departure from

13 the federal border search doctrine.

14   {27}   Determining the permissibility of a search or seizure involves balancing

15 governmental interests with the individual’s right to privacy. See Montoya de

16 Hernandez, 473 U.S. at 539-40. When individuals engage in certain courses of

17 action, their privacy interests may be diminished within the context of a permissible

18 search or seizure. See Almeida-Sanchez, 413 U.S. at 271. For example, when a gun



                                              15
 1 dealer “chooses to engage in [a] pervasively regulated business and to accept a federal

 2 license, he [or she] does so with the knowledge that his [or her] business records,

 3 firearms and ammunition will be subject to effective inspection.” Id. Likewise, an

 4 individual who presents himself or herself at an international border checkpoint for

 5 admission to the United States has a lesser expectation of privacy than he or she

 6 would have at an interior fixed checkpoint. See Montoya de Hernandez, 473 U.S. at

 7 539.

 8   {28}   We conclude that the extra layer of protection for motorists that New Mexico

 9 law provides is not a distinctive state characteristic that increases the individual’s

10 expectation of privacy at an international border checkpoint. Cardenas-Alvarez was

11 premised on the fact that motorists in New Mexico have a greater expectation of

12 privacy than that which is protected by federal law at interior fixed checkpoints.

13 2001-NMSC-017, ¶¶ 15-16. “Since not all individuals that are required to stop at a

14 permanent checkpoint have been outside the United States but are New Mexico

15 motorists lawfully traveling on New Mexico’s highways, New Mexico has an interest

16 in providing some protection to individuals who are compelled to pass through a

17 checkpoint.” Id. ¶ 53 (Baca, J., concurring in the result); see also Carroll v. United

18 States, 267 U.S. 132, 154 (1925) (“[T]hose lawfully within the country, entitled to use



                                             16
 1 the public highways, have a right to free passage without interruption or search unless

 2 there is known to a competent official, authorized to search, probable cause for

 3 believing that their vehicles are carrying contraband or illegal merchandise.”).

 4 However, traffic passing through an international border checkpoint is international

 5 in nature, not domestic. See United States v. Jackson, 807 F.2d 1185, 1192 (5th Cir.

 6 1986) (Reavley, J., specially concurring) (“[S]earches conducted at locations

 7 functionally equivalent to a border interdict the same kind of traffic stopped at our

 8 nation’s borders: international traffic.”), aff’d on reh’g, 825 F.2d 853 (5th Cir. 1987).

 9 Thus, traffic passing through international border checkpoints do not contain

10 domestic travelers who have heightened expectations of privacy that are idiosyncratic

11 to the state in which they are traveling; all international travelers have a lessened

12 expectation of privacy because they present themselves at the border for entry into the

13 United States. See Montoya de Hernandez, 473 U.S. at 539-40 (“[N]ot only is the

14 expectation of privacy less at the border than in the interior, the Fourth Amendment

15 balance between the interests of the Government and the privacy right of the

16 individual is also struck much more favorably to the Government at the border.”

17 (citations omitted)). Thus, the extra layer of protection that vindicates the privacy

18 interests of domestic travelers is not implicated at international border checkpoints.



                                              17
 1 We therefore decline to depart from the federal border search doctrine.

 2   {29}   We also note that fighting illegal immigration and smuggling present

 3 significant problems for federal law enforcement. See, e.g., Montoya de Hernandez,

 4 473 U.S. at 538 (“These cases reflect longstanding concern for the protection of the

 5 integrity of the border. This concern is, if anything, heightened by the veritable

 6 national crisis in law enforcement caused by smuggling . . . illegal narcotics . . . .”);

 7 Martinez-Fuerte, 428 U.S. at 552 (“Interdicting the flow of illegal entrants . . . poses

 8 formidable law enforcement problems.”). Differences between state and federal

 9 search and seizure rules create “very serious and, in some cases, seemingly insoluble

10 problems for law enforcement officials.” James W. Diehm, New Federalism and

11 Constitutional Criminal Procedure: Are We Repeating the Mistakes of the Past?, 55

12 Md. L. Rev. 223, 263 (1996). Such problems include the generation of choice of law

13 issues and the prospect of increasing litigation. See id. at 250-55. Therefore, we

14 conclude that departing from the federal border search doctrine would exacerbate law

15 enforcement issues at the international border.

16   {30}   The United States Supreme Court has stated that “[t]here is no war between the

17 [United States] Constitution and common sense.” Mapp v. Ohio, 367 U.S. 643, 657

18 (1961), limited on other grounds by United States v. Leon, 486 U.S. 897, 906, 928



                                              18
 1 (1984). Likewise, there is no need for the New Mexico Constitution to conflict with

 2 common sense.        “Federal-state cooperation in the solution of crime under

 3 constitutional standards will be promoted, if only by recognition of their . . . mutual

 4 obligation to respect the same fundamental criteria in their approaches.” Id. at 658.

 5 Our refusal to depart from the federal border search doctrine acknowledges the

 6 significant law enforcement problems at an international border checkpoint where it

 7 is known that a motorist is entering from outside the country, thereby vindicating

 8 common sense and furthering federal-state cooperation.

 9 CONCLUSION

10   {31}   We reverse the decision of the Court of Appeals in Sanchez, Ct. App. No.

11 32,994, and also reverse the district court’s suppression of the evidence.

12   {32}   IT IS SO ORDERED.
