   On March 25, 1988, your office requested our advice on whether the
Navy may authorize the U.S. Postal Inspection Service to use Navy drug-
detecting dogs, guided by Navy handlers, to identify postal packages con­
taining illegal narcotics. Upon review o f the provision o f the Posse
Comitatus Act contained in 18 U.S.C. § 1385, as well as related provisions
in title 10, we conclude that the Secretary o f the Navy has the discretion
to authorize such a use of Navy dogs and their handlers.1

                                I. The Posse Comitatus Act

   Congress enacted the Posse Comitatus Act (“Act”) in 1878 to address
Southern objections to the use of federal troops in civilian law enforce­
ment during the Reconstruction era. In its current form, the central pro­
vision o f the Act provides that:

            Whoever, except in cases and under circumstances ex­
          pressly authorized by the Constitution or Act of Congress,

 1 This conclusion is consistent with an earlier memorandum prepared by this Office See Use of
Department o f Defense Drug-Detectmg Dogs to Aid in Civilian Law Enforcement, 13 Op. O.L.C 185
(1989) ( “OLC Memorandum”). Several officials have sided with the contrary view o f James F Goodrich,
then-Under Secretary o f the Navy, that “the requested support is in conflict with the provisions o f the
Posse Comitatus Act. The use o f military d og handlers is considered to constitute direct involvement in
law enforcement activities and is thus illegal.” Memorandum for Commander in Chief o f the U.S. Pacific
Fleet, from James F. Goodrich, Under Secretary o f the Navy, Re Request fo r Loan o f Military Dogs (June

18 U.S.C. § 1385. By its terms, section 1385 does not apply to the Navy; the
words of the statute cover only the Army and the Air Force. Moreover,
courts considering the issue have held that the Act does not apply to the
Navy except by executive extension. United States v. Roberts, 

, 567 (9th Cir.), cert, denied, 

(1986); United States v. Del

, 116 (1st Cir.), cert, denied, 

(1984). See Memorandum for State Department Legal Advisor, from
Michael A. Carvin, Deputy Assistant Attorney General, Office of Legal
Counsel, Re: Assignment of Marine Personnel to the U.S. Mission to the
United Nations at 8 (May 10, 1988). See also United States v. Walden, 

, 374-76 (4th Cir.), cert, denied, 

(1974) (suggesting
that omission o f Navy was a drafting oversight but conceding that Navy
actions would not violate the letter of the Act).
  As a matter o f policy, the Department of Defense has extended the
Posse Comitatus Act to the Navy through regulations. 32 C.F.R. §
213.10(c) (1988). Those regulations make clear, however, that the
Secretary of the Navy retains the discretion to except situations from the
Act’s coverage “on a case-by-case basis.” 2 

conclude that
under the Posse Comitatus Act, the Secretary, within his discretion, may
authorize the use o f Navy drug dogs and their handlers contemplated by
the Postal Inspector.

                                   II. 10 U.S.C. Chapter 18

   In 1981, Congress revisited the question of military involvement in
civilian law enforcement. Although Congress did not alter section 1385, it
did add chapter 18 to title 10 o f the U.S. Code to provide for certain types
of military cooperation with civilian law enforcement officials. In partic­
ular, chapter 18 provides that the Secretary of Defense “may ... make
available any equipment... of the Department o f Defense to any Federal,
State, or local civilian law enforcement official for law enforcement pur­
poses.” 10 U.S.C. § 372. No one has questioned (and we have no reason to
doubt) that drug-detecting dogs are to be considered “equipment” for pur­
poses o f this provision. Thus understood, section 372 provides express
authorization for that which section 1385 does not bar: the loaning of
Navy dogs to civilian law enforcement authorities.

   2 Exceptions that are likely to involve participation by Navy personnel in the “interdiction o f a vessel
or aircraft, a search or seizure, an arrest, or other activity that is likely to subject civilians to the exercise
o f military power that is regulatory, proscriptive, or compulsory in nature” require the advance approval
o f the Secretary o f Defense, as well. 32 C FR. § 213 10(c)(2)

                                                     313
    In section 375, however, Congress provided that the provision of equip­
ment to civilian law enforcement personnel under section 372 does not
permit “direct participation by a member o f the Army, Navy, Air Force,
or Marine Corps in a search and seizure, an arrest, or other similar activ­
ity unless participation in such activity by such member is otherwise
authorized by law.” 10 U.S.C. § 375 (emphasis added). Thus, some ques­
tion remains whether section 375 would permit the Navy also to provide
the Postal Inspector with the Navy dogs’ handlers, without whom the
dogs would be useless.3
    For two reasons, we conclude that section 375 does not bar the Postal
Inspector’s use o f the Navy dogs and their handlers. First, in the 1981
enactment, Congress made clear that nothing in the new provisions was
to be “construed to limit the authority o f the executive branch in the use
o f military personnel or equipment for civilian law enforcement purpos­
es beyond that provided by law before December 1, 1981.” 10 U.S.C. §
378. Thus, Congress did not intend in 1981 to bar any military involve­
ment in civilian law enforcement that had been permissible under section
1385 and the Department of Defense regulations enacted thereunder. The
Conference Report confirms this conclusion. It states that:

          Section 378 clarifies the intent o f the conferees that the
          restrictions on the assistance authorized by the new chap­
          ter [18] in title 10 apply only to the authority granted under
          that chapter. Nothing in this chapter should be construed to
          expand or amend the Posse Comitatus Act. In particular,
          because that statute, on its face, includes the Army and Air
          Force, and not the Navy and Marine Corps, the conferees
          wanted to ensure that the conference report would not be
          interpreted to limit the authority of the Secretary of
          Defense to provide Navy and Marine Corps assistance
          under, for example, 21 U.S.C. 873(b). However, nothing in
          this chapter was in any way intended to rescind or direct
          the recision o f any current regulations applying the policies
          and terms o f the Posse Comitatus Act to the activities of the
          Navy or Marine Corps.

  Second, section 375 prohibits only the “direct participation” o f military
forces in civilian law enforcement. Here, by contrast, Navy dogs and per­

  3 Although 10 U S.C. § 373(1) would permit Navy personnel to train civilian Postal Inspectors to handle
the dogs, we understand that substitution o f different human handlers is not practicable
  4 The provision cited as an example by the Conference Report specifies that, upon a request by the
Attorney General, “it shall be the duty o f any agency or instrumentality o f the Federal Government to fur­
nish assistance ... to him for carrying out his functions [concerning the control o f drug trafficking!.” 21
U.S C. § 873(b).

                                                   314
sonnel would merely identify packages containing drugs. As we under­
stand the proposal, the actual “search and seizure” o f the package would
be performed by civilian Postal Inspectors.5 The legislative history o f sec­
tion 375 shows that Congress intended that provision to bar only the
exercise o f military authority in direct confrontations with civilians.6
During the hearings on chapter 18, for example, Representative Hughes,
the Chairman o f the Subcommittee on Crime, observed that:

         I can understand where you might have to have military
         personnel, actually operate [in a law enforcement capacity]
         under given circumstances. I understand that. But that is a
         long way from giving them the authority to make an arrest
         or to make a seizure.

           An assist, as opposed to a military person making an arrest
         or participating in a seizure is an important distinction.

Posse Comitatus Act: Hearing on H.R. 3519 Before the Subcomm. on
Crime of the House Comm, on the Judiciary, 97th Cong., 1st Sess. 28
(1981). During the same exchange, William H. Taft IV, then-General
Counsel o f the Department of Defense, concurred with Representative
Hughes’s distinction by stating that:

         I think that you have correctly identified the significance of
         the arrest and the seizure actions.... I think that it is the
         arrests and the seizures, and active — putting, really, into a
         confrontation, an immediate confrontation, the military
         and a violator o f a civilian statute, that causes us the great­
         est concern.

   These observations were by no means novel. The Appendix o f materi­
als before the Subcommittee contains an opinion by this Office noting
that the Posse Comitatus Act does not prohibit military assistance to
civilian law enforcement where “there is no contact with civilian targets
of law enforcement, no actual or potential use of military force, and no
military control over the actions o f civilian officials.”

  6 The precise relationship between constitutional doctrines o f “search and seizure” and the meaning o f
the same terms in section 375 remains unclear The Supreme Court has held, however, that the use o f
drug-detecting dogs to identify luggage containing drugs does not constitute a “search” for purposes o f
the Fourth Amendment United States v Place, 462 U S. 696, 707 (1983).
  GThis position is consistent with our earlier guidance concerning section 375. See OLC Memorandum,
13 Op. O.L.C at 186.

Counsel at 13 (Mar. 24, 1978).7 Accordingly, where, as here, the Navy dogs
and personnel will not be used in direct confrontations with civilians,
section 375 would not bar their use in civilian law enforcement efforts.

                                         III. Conclusion

   We conclude that the Secretary o f the Navy retains the discretion under
the Posse Comitatus Act and Department of Defense regulations to
authorize the use by the Postal Inspector o f Navy drug-detecting dogs and
their handlers to identify packages containing illegal narcotics. The pro­
vision in 10 U.S.C. § 375 restricting the direct participation o f military per­
sonnel in civilian law enforcement efforts does not prevent the Secretary
from authorizing the proposed use because (i) that provision does not
limit the Secretary’s authority under Department o f Defense regulations
to make exceptions to the application o f the Posse Comitatus Act and (ii)
the proposed use o f the dogs and their handlers will not involve con­
frontation with civilians.

  7 Subsequent congressional action with respect to section 375 confirms this understanding o f the 1981
legislative history In 1988, Congress amended section 375 by deleting from the list o f prohibited activities
“interdiction o f a vessel or aircraft ” See 10 U.S C. § 375 note The Conference Report on the 1988 amend­
ments states that Congress took such action “because the term ‘interdiction’ has acquired a meaning that
includes detection and monitoring as well as a physicaJ interference with the movement o f a vessel or
aircraft.” H.R. Conf. Rep No. 989, 100th Cong., 2d Sess. 452 (1988). Congress thus clarified that such pre­
liminary law enforcement tasks as “detection” do not com e within section 375, whereas actual “physical
interference” with a civilian remains barred by that provision’s reference to “seizure[s]." Id
