    LYNCH, Circuit Judge.   The United States  District
    LYNCH, Circuit Judge
    Court granted  a  writ  of  habeas  corpus  to  Lui  Kin-Hong
    ("Lui"),  who  sought  the  writ  after  a  magistrate  judge
    certified  to the  Secretary of  State that  she may,  in her
    discretion, surrender Lui for extradition to the Crown Colony
    of Hong Kong.   The United Kingdom,  on behalf of Hong  Kong,
    had  sought Lui's extradition on a warrant for his arrest for
    the crime of bribery.   Lui's petition for habeas  corpus was
    premised on the fact that  the reversion of Hong Kong to  the
    People's Republic of China  will take place on July  1, 1997,
    and it  will be impossible for the Crown Colony to try and to
    punish Lui before that date.  The United States  appeals.  We
    reverse  the order of the district court granting the writ of
    habeas corpus.
    The  United States  argues that  Lui is  within the
    literal terms of the  extradition treaties between the United
    States and the United  Kingdom, that the courts may  not vary
    from the language of the treaties, and that the certification
    must issue.   Lui argues  that the language  of the  treaties
    does  not permit  extradition,  an argument  which is  surely
    wrong.   Lui's more serious  argument is that  the Senate, in
    approving the treaties, did not mean to permit extradition of
    someone to  be tried and  punished by a  government different
    from the  government which has  given its  assurances in  the
    treaties.
    Lui  does not  claim that  he faces  prosecution in
    Hong Kong on  account of his race, religion,  nationality, or
    political opinion.   He does not  claim to be charged  with a
    political offense.   The treaties give  the courts a  greater
    role  when  such considerations  are  present.   Here,  Lui's
    posture is that of  one charged with an ordinary crime.   His
    claim is  that  to surrender  him  now to  Hong  Kong is,  in
    effect, to send him  to trial and punishment in  the People's
    Republic of  China.  The  Senate, in approving  the treaties,
    could  not have intended such a result, he argues, and so the
    court should interpret the  treaties as being inapplicable to
    his case.  Absent a treaty permitting extradition, he argues,
    he may not be extradited.
    While Lis it persuasive.  The Senate was well aware
    of the reversion when it approved a supplementary treaty with
    the United Kingdom  in 1986.   The Senate  could easily  have
    sought language to address  the reversion of Hong Kong  if it
    were  concerned,  but  did not  do  so.    The President  has
    recently executed  a new treaty with  the incoming government
    of  Hong Kong, containing the same guarantees that Lui points
    to  in  the  earlier  treaties,  and  that  treaty  has  been
    submitted  to the  Senate.  In  addition, governments  of our
    treaty partners often change, sometimes by  ballot, sometimes
    by revolution  or other means,  and the  possibility or  even
    certainty of  such change  does not itself  excuse compliance
    -4-
    4
    with  the  terms of  the agreement  embodied in  the treaties
    between the countries.  Treaties contain  reciprocal benefits
    and  obligations.    The  United  States  benefits  from  the
    treaties  at   issue  and,   under  their  terms,   may  seek
    extradition  to the date of  reversion of those  it wants for
    criminal offenses.
    Fundamental  principles  in our  American democracy
    limit the role of courts in certain matters, out of deference
    to the  powers allocated by the Constitution to the President
    and to the  Senate, particularly  in the  conduct of  foreign
    relations.   Those  separation  of  powers  principles,  well
    rehearsed in extradition law,  preclude us from rewriting the
    treaties which  the President  and the Senate  have approved.
    The  plain language  of the  treaties does  not support  Lui.
    Under the treaties  as written,  the courts may  not, on  the
    basis of the  reversion, avoid certifying to the Secretary of
    State  that Lui may be  extradited.  The  decision whether to
    surrender  Lui,  in  light  of  his  arguments,  is  for  the
    Secretary of State to make.
    This is not to say American courts acting under the
    writ of habeas corpus, itself guaranteed in the Constitution,
    have no independent  role.  There  is the ultimate  safeguard
    that  extradition  proceedings  before  United  States courts
    comport  with the Due Process Clause of the Constitution.  On
    the facg presenting a  serious constitutional issue of denial
    -5-

    of due process.  Some future case may, on  facts amounting to
    a  violation of  constitutional guarantees,  warrant judicial
    intervention.  This case does not.
    I.
    We repeat  the facts essentially as  we stated them
    in  our earlier opinion.   United States v.  Lui Kin-Hong, 
    83 F.3d 523
     (1st Cir. 1996) (reversing district court's decision
    to release Lui on bail).
    Lui  is charged  in  Hong Kong  with conspiring  to
    receive and receiving over US $3 million in bribes from Giant
    Island  Ltd. ("GIL")  or GIL's  subsidiary, Wing  Wah Company
    ("WWC").    Lui, formerly  a senior  officer  of the  Brown &
    Williamson  Co., was  "seconded"  in 1990  to its  affiliated
    company, the  British American  Tobacco Co. (Hong  Kong) Ltd.
    ("BAT-HK"), where he became Director of Exports in 1992.  The
    charges  result  from  an  investigation  by  the  Hong  Kong
    Independent Commission Against Corruption ("ICAC").  The Hong
    Kong authorities charge  that GIL  and WWC,  to which  BAT-HK
    distributed  cigarettes, paid  bribes  in excess  of HK  $100
    million  (approximately US $14 to $15 million) to a series of
    BAT-HK executives, including Lui.   The bribes were allegedly
    given in exchange  for a  virtual monopoly on  the export  of
    certain  brands of  cigarettes  to the  People's Republic  of
    China  ("PRC")   and  to   Taiwan.    Among   the  cigarettes
    -6-
    6
    distributed  were the  popular Brown  & Williamson  brands of
    Kent,  Viceroy,  and  Lucky  Strike.   GIL  purchased  three-
    quarters  of a  billion dollars  in cigarettes  from 1991  to
    1994, mostly from BAT-HK.
    A  former GIL  shareholder, Chui  To-Yan ("Chui"),
    cooperated  with the authorities and, it  is said, would have
    provided evidence  of Lui's  acceptance of  bribes.  Some  of
    Lui's alleged co-conspirators attempted to dissuade Chui from
    cooperating.     Chui  was   later  abducted,  tortured,  and
    murdered.  The ICAC  claims that the murder was  committed to
    stop Chui from testifying.  Lui  is not charged in the murder
    conspiracy.    Lui  was  in the  Philippines  (which  has  no
    extradition treaty with  Hong Kong) on  a business trip  when
    the Hong  Kong authorities unsuccessfully sought  to question
    him in April  1994.  Lui has not returned  to Hong Kong since
    then.
    At the request of the United Kingdom ("UK"), acting
    on behalf of Hong  Kong, United States marshals arrested  Lui
    as  he got off a plane at  Boston's Logan Airport on December
    20, 1995.  The arrest was for the  purpose of extraditing Lui
    to Hong Kong.1   The  government asked that  Lui be  detained
    pending  completion  of  the  extradition proceedings.    The

    Kong authorities is dated February 5, 1996; there were
    earlier warrants.

    magistrate judge, after a hearing, denied Lui's request to be
    released on bail.
    The district court, on April 25, 1996, reversed the
    order  of the magistrate judge  and released Lui  on bail and
    conditions.  Lui Kin-Hong v. United States, 
    926 F. Supp. 1180
    (D.  Mass. 1996).  The district court held that the reversion
    of Hong Kong to the PRC on July 1, 1997, raised complex legal
    issues  that  would  result  in  protracted  proceedings  and
    presented a "special circumstance" overriding the presumption
    against bail.  
    Id. at 1189
    .  That court also found that there
    were conditions of release that would adequately ensure Lui's
    presence at future  proceedings.   
    Id. at 1196
    .   This  court
    reversed the district court and, on May 14, 1996, ordered Lui
    held pending the resolution  of the extradition certification
    issue.  Lui, 
    83 F.3d at 525
    .
    The magistrate judge commenced extradition hearings
    on  May 28, 1996.   Those proceedings,  during which evidence
    was  taken, lasted  three days.   The magistrate  judge found
    that  there  was  probable  cause  to believe  that  Lui  had
    violated Hong Kong law on  all but one of the charges  in the
    warrant.2   Magistrate Judge Karol,  pursuant to 18  U.S.C.
    3184,    issued   a   careful   decision   certifying   Lui's
    extraditability on August 29, 1996.  In re Extradition of Lui

    Kin-Hong  ("Lui Extradition"),  
    939 F. Supp. 934
     (D.  Mass.
    1996).  On September  3, 1996, Lui filed an  amended petition
    for  a writ  of habeas  corpus, the  only avenue  by which  a
    fugitive sought for extradition  (a "relator") may attack the
    magistrate judge's decision,3 with the district court.
    After  a  hearing,  the  district  court  issued  a
    memorandum and order  granting the writ  on January 7,  1997.
    Lui Kin-Hong v. United States ("Lui Habeas"), --- F. Supp. --
    -,   
    1997 WL 37477
     (D.  Mass. Jan. 7,  1997).   The district
    court reasoned that, because  the Crown Colony could  not try
    Lui and punish him before the reversion date, the extradition
    treaty  between  the  United  States and  the  UK,  which  is
    applicable to Hong Kong, prohibited extradition.  
    Id.
     at ---,
    *4-*5.   Because  no  extradition treaty  between the  United
    States and the new government of Hong Kong has been confirmed
    by the United States Senate, the district court reasoned, the
    magistrate    judge    lacked    jurisdiction   to    certify
    extraditability.  See 
    id.
     at ---, *5-*11.  The district court
    denied the government's motion for reconsideration on January
    13,  1997.  This court then stayed the district court's order
    and expedited the present appeal.
    3.  Due to the limited function of an extradition proceeding,
    there is no direct appeal from a judicial officer's
    certification of extraditability.  See Collins v. Miller, 
    252 U.S. 364
    , 369-70 (1920).  A habeas petition is therefore the
    only mechanism by which a relator may seek review.

    At the time Lui was arrested  in Boston in December
    1995, more than eighteen months remained before the reversion
    of  Hong Kong  to  the PRC  on  July 1,  1997.   The  various
    proceedings in our court system have now occupied fifteen  of
    those months, as the magistrate judge and district judge have
    given careful consideration to the issues.
    II.
    The extradition request  was made  pursuant to  the
    Extradition  Treaty  Between  the  Government  of the  United
    States of America and the Government of the United Kingdom of
    Great Britain and  Northern Ireland, June 8, 1972,  28 U.S.T.
    227 (the  "Treaty"), as  amended by the  Supplementary Treaty
    Between the Government  of the United  States of America  and
    the Government  of the  United Kingdom  of Great  Britain and
    Northern  Ireland, June  25,  1985, T.I.A.S.  No. 12050  (the
    "Supplementary  Treaty").4    The  original  Treaty was  made
    applicable to Hong Kong,  among other British territories, by
    an  exchange of  diplomatic notes  on October  21, 1976.   28
    U.S.T. at 238-41.5  The Supplementary Treaty is applicable to
    4.  We refer to the Treaty and the Supplementary Treaty as
    "the Treaties."
    5.  By its terms, the Treaty applies to the UK, and, in
    addition, to "any territory for the international relations
    of which the United Kingdom is responsible and to which the
    Treaty shall have been extended by agreement between the
    Contracting Parties embodied in an Exchange of Notes."

    upon six months written notice, to terminate the application

    Hong  Kong by its terms.   Supplementary Treaty,  art. 6(a) &
    Annex.
    Hong Kong's status  as a Crown Colony  is coming to
    an end on July  1, 1997, when Hong Kong is to  be restored to
    the PRC.  The  impending reversion, at the expiration  of the
    UK's ninety-nine year leasehold,  was formally agreed upon by
    the UK and the PRC in 1984; the United States was not a party
    to this agreement.  See  Joint Declaration of the  Government
    of the United Kingdom  of Great Britain and Northern  Ireland
    and the Government of  the People's Republic of China  on the
    Question  of Hong Kong,  Dec. 19, 1984,  ratified and entered
    into  force  May 27,  1985, T.S.  No.  26 (1985)  (the "Joint
    Declaration").  Under the terms of the Joint Declaration, the
    PRC  "declares" its  "basic  policies" with  respect to  Hong
    Kong.   
    Id.
       art.  3.   The PRC  states that  it intends  to
    establish  a  "Hong   Kong  Special  Administrative   Region"
    ("HKSAR"),  
    id.
     art. 3(1), which will enjoy a "high degree of
    autonomy except  in foreign and  defence affairs."   
    Id.
     art.
    3(2).  In addition,  the PRC states that  the HKSAR "will  be
    vested  with . . . independent judicial power, including that
    of final adjudication" and that  the "laws currently in force
    in Hong  Kong will  remain  basically unchanged."

    of the Treaty as to any territory to which the Treaty was
    extended under article II(1)(a).

    our knowledge, neither party has attempted to invoke this
    provision to terminate the application of the Treaty to Hong
    Kong.

    Declaration,  to "remain unchanged  for 50 years."   
    Id.
     art.
    3(12).
    United   States   Senate   ratification    of   the
    Supplementary Treaty  occurred on  July 17, 1986,  well after
    the widely publicized signing of the Joint Declaration.   See
    132  Cong. Rec. 16,819 (1986).  Clearly, the Senate was aware
    of the  planned reversion when it  approved the applicability
    to Hong Kong of the Supplementary Treaty.6  The Supplementary
    Treaty does not  contain an  exception for  relators who  can
    show that their trial or punishment will occur after the date
    of reversion.   Indeed, the Supplementary  Treaty is entirely
    silent on the question of reversion.
    The  United States  does  not  have an  extradition
    treaty  with the  PRC.   However, on  December 20,  1996, the
    United   States  signed  an   extradition  treaty   with  the
    government  of   the  nascent  HKSAR,   which  provides   for
    reciprocal post-reversion extradition.  See Agreement Between
    the  Government  of  the United  States  of  America and  the
    Government  of  Hong  Kong  for  the  Surrender  of  Fugitive
    Offenders,  Dec. 20, 1996 (the "New Treaty").  The New Treaty
    will not enter into  force until the Senate gives  its advice
    6.  See, e.g., 132 Cong. Rec. 16,598 (1986) (statement of
    Sen. Hatch) (commenting on applicability of Supplementary
    Treaty to Hong Kong).

    and consent.   It was  submitted to  the Senate  on March  3,
    1997.  See 143 Cong. Rec. S1846 (daily ed. Mar. 3, 1997).
    A.  United States Extradition Procedure
    In   the  United   States,   the   procedures   for
    extradition  are governed by statute.  See 18 U.S.C. ch. 209.
    The statute  establishes a  two-step procedure  which divides
    responsibility  for extradition  between a  judicial officer7
    and  the Secretary of  State.  The  judicial officer's duties
    are set  out in  18 U.S.C.    3184.   In brief,  the judicial
    officer,  upon complaint,  issues  an arrest  warrant for  an
    individual sought for extradition,  provided that there is an
    extradition treaty between the United States and the relevant
    foreign government  and that the crime charged  is covered by
    the  treaty.   See 
    id.
       If  a warrant  issues, the  judicial
    officer then conducts a hearing to determine if "he deems the
    evidence   sufficient  to  sustain   the  charge   under  the
    provisions  of  the proper  treaty."   
    Id.
       If  the judicial
    officer makes such a determination, he "shall certify" to the
    Secretary  of State that a  warrant for the  surrender of the
    relator "may  issue."   
    Id.
     (emphases added).   The  judicial
    officer is  also directed to  provide the Secretary  of State
    with  a   copy  of  the  testimony  and   evidence  from  the
    extradition hearing.  Id.
    7.  The judicial officer may be any federal judge, any
    authorized magistrate, or any state judge of a court of
    general jurisdiction.  See id.   3184.
    -13-
    13
    It  is then  within the  Secretary of  State's sole
    discretion  to determine  whether or  not the  relator should
    actually be extradited.  See 18 U.S.C.   3186 ("The Secretary
    of  State  may order  the  person  committed under  section[]
    3184 . . . of this  title to  be delivered to  any authorized
    agent of such  foreign government . . . .") (emphasis added).
    The  Secretary  has  the  authority to  review  the  judicial
    officer's findings  of fact and conclusions  of law de novo,8
    and  to  reverse  the  judicial  officer's  certification  of
    extraditability   if   she   believes   that   it   was  made
    erroneously.9 See 4  Abbell & Ristau,  International Judicial
    Assistance:  Criminal -  Extradition    13-3-8(2),  at 266-69
    (1995); Note, Executive Discretion  in Extradition, 
    62 Colum. L. Rev. 1313
    , 1316-25 (1962).  The Secretary may also decline
    to  surrender  the relator  on  any  number of  discretionary
    grounds,  including  but  not  limited  to, humanitarian  and
    8.    While not required to by statute, the Department of
    State routinely accepts written submissions from relators in
    conjunction with its review of extraditability.  4 Abbell &
    Ristau, International Judicial Assistance:  Criminal --
    Extradition,   13-3-8(5), at 274 (1995).
    9.  Although at first glance, this procedure might appear to
    be of questionable constitutionality because it subjects
    judicial decisions to executive review, rendering them non-
    final, cf. Hayburn's Case, 2 U.S. (2 Dall.) 409 (1792), it
    has been held that the judicial officer in an extradition
    proceeding "is not exercising 'any part of the judicial power
    of the United States,'" and instead is acting in "a non-
    institutional capacity."  United States v. Howard, 
    996 F.2d 1320
    , 1325 (1st Cir. 1993) (quoting In re Kaine, 55 U.S. (14
    How.) 103, 120 (1852)).

    foreign policy considerations.  See 4 Abbell & Ristau, supra,
    13-3-8(3),   at   269-73;  II   Bassiouni,   International
    Extradition: United  States Law and  Practice 601-04  (1987).
    Additionally,  the  Secretary may  attach  conditions to  the
    surrender  of the  relator.   See  Jimenez  v. United  States
    District Court,  
    84 S. Ct. 14
    , 19  (1963)  (Goldberg,  J.,
    chambers  opinion) (denial  of stay)  (describing commitments
    made by Venezuelan government  to United States Department of
    State  as a condition of  surrender of fugitive);  4 Abbell &
    Ristau, supra,    13-3-8(4), at 273-74;  II Bassiouni, supra,
    at 604.10  The State Department alone, and not the judiciary,
    has  the   power  to  attach   conditions  to  an   order  of
    extradition.   See,  e.g.,  Emami v.  United States  District
    Court,  
    834 F.2d 1444
    , 1453  (9th Cir.  1987); Demjanjuk  v.
    Petrovsky, 
    776 F.2d 571
    , 584 (6th Cir. 1985).  Of course, the
    Secretary may also  elect to use diplomatic methods to obtain
    fair treatment for the  relator.  See, Note, supra,  at 1325-
    26; cf. In re Normano, 
    7 F. Supp. 329
    , 329 (D. Mass. 1934).
    Thus,  under  18  U.S.C.      3184,  the   judicial
    officer's  inquiry  is limited  to  a  narrow  set of  issues
    concerning the  existence of  a treaty, the  offense charged,
    and  the quantum of evidence offered.   The larger assessment
    10.  The United States has, for example, imposed conditions
    as to the type of trial the relator would receive (e.g., in
    civil, rather than martial law, court) and as to security
    arrangements for the relator.  4 Abbell & Ristau, supra,
    13-3-8(4), at 273 n.1.

    of  extradition  and its  consequences  is  committed to  the
    Secretary of State.      This  bifurcated procedure  reflects
    the fact  that extradition proceedings  contain legal  issues
    peculiarly  suited for judicial resolution, such as questions
    of the standard of proof,  competence of evidence, and treaty
    construction,  yet  simultaneously  implicate   questions  of
    foreign policy,  which are  better answered by  the executive
    branch.    Both institutional  competence rationales  and our
    constitutional structure, which places primary responsibility
    for  foreign  affairs in  the  executive  branch, see,  e.g.,
    United States  v. Curtiss-Wright Export Corp.,  
    299 U.S. 304
    ,
    319-22 (1936), support this division of labor.
    In    implementing    this    system    of    split
    responsibilities  for  extradition,  courts   have  developed
    principles  which  ensure,  among  other   things,  that  the
    judicial   inquiry  does   not  unnecessarily   impinge  upon
    executive  prerogative  and  expertise.    For  example,  the
    executive branch's  construction of  a  treaty, although  not
    binding upon the courts, is entitled to great weight.  Factor
    v.  Laubenheimer, 
    290 U.S. 276
    , 295 (1933); cf. United States
    v. Howard, 
    996 F.2d 1320
    , 1330 n.6 (1st Cir. 1993) (deference
    to executive in extradition context stems, at least in  part,
    from  fact  that  executive  wrote  and negotiated  operative
    documents).  Another principle is that extradition  treaties,
    unlike criminal  statutes, are  to be construed  liberally in
    -16-
    16
    favor of enforcement  because they  are "in  the interest  of
    justice  and friendly international  relationships."  Factor,
    
    290 U.S. at 298
    .   These principles of  construction require
    courts to:
    interpret extradition treaties to produce
    reciprocity between,  and expanded rights
    on    behalf    of,   the    signatories:
    "[Treaties] should be liberally construed
    so as to effect the apparent intention of
    the  parties  to   secure  equality   and
    reciprocity  between  them.     For  that
    reason, if  a treaty fairly admits of two
    constructions, one restricting the rights
    which may  be claimed  under it,  and the
    other  enlarging  it,  the  more  liberal
    construction is to be preferred."
    Howard, 
    996 F.2d at 1330-31
     (quoting Factor, 
    290 U.S. at
    293-
    94).
    Another  principle that  guides  courts in  matters
    concerning extradition is the rule of non-inquiry.  More than
    just a  principle of  treaty construction, the  rule of  non-
    inquiry  tightly limits  the  appropriate  scope of  judicial
    analysis  in an  extradition proceeding.   Under the  rule of
    non-inquiry, courts refrain from "investigating  the fairness
    of a  requesting nation's justice  system," id. at  1329, and
    from inquiring "into the  procedures or treatment which await
    a   surrendered   fugitive   in   the   requesting  country."
    Arnbjornsdottir-Mendler v. United States,  
    721 F.2d 679
    ,  683
    (9th Cir. 1983).   The rule of non-inquiry,  like extradition
    procedures   generally,   is   shaped   by   concerns   about
    institutional  competence  and by  notions  of  separation of
    -17-
    17
    powers.   See United States  v. Smyth, 
    61 F.3d 711
    , 714 (9th
    Cir. 1995).11  It is not that questions about what awaits the
    relator  in   the  requesting  country   are  irrelevant   to
    extradition;  it   is  that   there  is  another   branch  of
    government, which  has both final say  and greater discretion
    in  these  proceedings,  to  whom these  questions  are  more
    properly addressed.12
    11.  One commentator has analogized the rule of non-inquiry
    to the "act of state" doctrine, which prohibits United States
    courts from judging the governmental acts of a foreign
    country performed within its own territory.  See Semmelman,
    Federal Courts, The Constitution, and The Rule of Non-Inquiry
    in International Extradition Proceedings, 
    76 Cornell L. Rev. 1198
     (1991).  The "act of state" doctrine, the Supreme Court
    has said, "arises out of the basic relationships between
    branches of government in a system of separation of powers.
    It concerns the competency of dissimilar institutions to make
    and implement particular kinds of decisions in the area of
    international relations."  Banco Nacional de Cuba v.
    Sabbatino, 
    376 U.S. 398
    , 423 (1964).  This court has doubted,
    in dicta, that the rule of non-inquiry is constitutionally
    mandated.  Howard, 
    996 F.2d at
    1330 n.6.  Whether the
    doctrine is constitutionally mandated is immaterial here.
    12.  Nor is it true, as Lui suggests, that the rule of non-
    inquiry is only appropriate where the existence of a treaty
    reflects a substantive judgment about the fairness of another
    nation's procedures.  The United States has maintained, over
    time, extradition treaties with some of the world's most
    oppressive and arbitrary regimes.  See 18 U.S.C.   3181
    (listing treaties of extradition and dates entered into).
    The rule of non-inquiry expresses no judgment about a foreign
    nation's ability and willingness to provide justice; it
    simply defers that assessment to the second part of every
    extradition proceeding -- review of extraditability and
    determination of the appropriateness of surrender by the
    Secretary of State.  Indeed, a leading commentator, in
    discussing the scope of the Secretary's discretion under 18
    U.S.C.   3186, has argued that it is precisely "because of
    the rule of non-inquiry" that it is appropriate for the
    Secretary to exercise discretion on humanitarian grounds.  II
    Bassiouni, supra, at 602 (emphasis added).
    -18-

    Lui contends  that, on July 1,  1997, the reversion
    of Hong Kong to the PRC will result in his being subjected to
    trial and punishment by a regime with which the United States
    has no extradition  treaty.  This  future event, Lui  argues,
    operates retroactively  to render his extradition illegal, as
    of today,  because, he  says, extradition is  only legitimate
    where trial and punishment will be administered by the regime
    with which the United States has a treaty.
    Although Lui  is  correct that  the government  has
    conceded  that he will not  be tried before  reversion, it is
    also quite  possible that  the scenario he  depicts will  not
    arise.   The  new extradition  treaty with  the HKSAR  may be
    approved  by   the  United  States  Senate,   establishing  a
    continuity  of treaties  through and  beyond July  1, 1997.13
    The United States government may choose to extend the current
    Treaty by executive  agreement.14  To  the extent that  Lui's
    13.  The government does not argue that, absent any other
    action and of their own accord, the Treaties would continue
    beyond reversion to apply to Hong Kong.  Accordingly, on the
    facts of this case, we find the discussion of the state
    succession doctrine in Terlinden v. Ames, 
    184 U.S. 270
    (1902), a case heavily relied upon by the district court, see
    Lui Habeas, --- F. Supp. at ---, 
    1997 WL 37477
    , at *4-*5, to
    be of little assistance to Lui.  Of course, the discussion in
    Terlinden of the rule of non-inquiry is relevant, and
    supports our analysis.
    14.  It may be argued that this alternative infringes upon
    the Senate's prerogative, under the Treaty Clause, U.S.
    Const., art. II,   2, to give its advice and consent.  But it
    is hardly an appropriate judicial task to attempt to resolve
    a hypothetical and not ripe dispute between the legislature
    and the executive.
    -19-
    19
    argument depends on the fairness of the procedures he will be
    subjected to,  he asks this court to decide that the PRC will
    not adhere to the Joint Declaration  with the UK, in which it
    declared its  intention to maintain Hong  Kong's legal system
    for fifty years.
    All  of these  questions involve  an evaluation  of
    contingent political events.  The Supreme Court has said that
    the indicia of a non-justiciable political question include:
    a  textually demonstrable  constitutional
    commitment  of the issue  to a coordinate
    political  department;  or   a  lack   of
    judicially  discoverable  and  manageable
    standards  for  resolving   it;  or   the
    impossibility  of   deciding  without  an
    initial  policy  determination of  a kind
    clearly  for  nonjudicial discretion;  or
    the    impossibility    of   a    court's
    undertaking     independent    resolution
    without  expressing  lack of  respect due
    coordinate branches of government;  or an
    unusual need  for unquestioning adherence
    to a political decision already  made; or
    the  potentiality  of embarrassment  from
    multifarious  pronouncements  by  various
    departments on one question.
    Baker v.  Carr, 
    369 U.S. 186
    ,  217 (1962).  While  not all of
    these ingredients  are present here, several  are.  Moreover,
    unlike  many "political questions,"  whose resolution, absent
    judicial  determination,  must  await  the  vagaries  of  the
    political  process, here  there is  a statutory  scheme which
    provides  for  the  resolution   of  these  questions  by  an
    identified  member of  the  executive branch.   The  case for
    -20-
    20
    judicial  resolution  is  thus  weaker than  with  many  such
    questions.
    The   principles   of   reciprocity   and   liberal
    construction  also counsel against construing the Treaties so
    as to  prohibit Lui's  extradition.   Hong Kong,  through the
    United  Kingdom,  has  entered bilateral  treaties  with  the
    United  States.  The United  States has sought extradition of
    criminals  from  Hong  Kong in  the  past,  and  may wish  to
    continue to  do so up until  July 1, 1997.   If the executive
    chooses  to modify or abrogate the terms of the Treaties that
    it negotiated, it has ample discretion to do so.  However, if
    this court were to read a cut-off date vis-a-vis extraditions
    to  Hong Kong into the Treaties, it would risk depriving both
    parties of the benefit of their bargain.
    None  of  these principles,  including non-inquiry,
    may be regarded as an absolute.  We, like the Second Circuit,
    "can imagine situations where the relator, upon  extradition,
    would be subject to  procedures or punishment so antipathetic
    to  a  federal  court's  sense  of   decency  as  to  require
    reexamination of the principle[s]"  discussed above.  Gallina
    v. Fraser,  
    278 F.2d 77
    , 79 (2d Cir. 1960).  This is not such
    a  case.    Lui  is  wanted  for  economic,  not   political,
    activities  whose  criminality  is  fully  recognized in  the
    United States.  His extradition is sought by the current Hong
    Kong regime, a colony of Great Britain, which, as Lui himself
    -21-
    21
    points  out,  is one  of this  country's most  trusted treaty
    partners.  Moreover, Lui  has been a fugitive from  Hong Kong
    since  1994.    He  has been  subject  to  extradition  since
    entering the United States in December 1995.  That now only a
    few months remain before the reversion of Hong Kong is partly
    attributable to strategic choices made by Lui himself.  There
    is nothing here which shocks the conscience of this court.
    B.  The Treaties
    There  is   no   dispute  that   the   Treaty,   as
    supplemented  by the  Supplementary  Treaty, is  currently in
    effect and is applicable  to Hong Kong.  The  district court,
    in granting Lui's habeas petition, reasoned that "the Treaty,
    by its  own terms, does not allow the extradition of a person
    to Hong  Kong if the Crown  Colony of Hong Kong  is unable to
    try and to punish that person."   Lui Habeas, --- F. Supp. at
    ---, 
    1997 WL 37477
    , at *5.  The government counters that the
    terms of the Treaty clearly  allow Lui's extradition.   There
    is nothing in the  plain language of the Treaties  that would
    permit  the  construction made  by the  district court.   The
    principles discussed above argue persuasively against reading
    judicially created limitations into the Treaties' unambiguous
    text.
    1.  Overview
    We begin our analysis of the Treaties with  a brief
    overview of the Treaties' operative provisions.  Article I of
    -22-
    22
    the  Treaty  states the  basic reciprocal  compact, providing
    that:
    Each Contracting Party undertakes to
    extradite   to   the   other,    in   the
    circumstances   and    subject   to   the
    conditions specified in this  Treaty, any
    person found  in  its territory  who  has
    been  accused or convicted of any offense
    within Article III, committed  within the
    jurisdiction of the other Party.
    Treaty, art. I.
    Article   III   contains  the   "dual  criminality"
    requirement, a  requirement that is "central   to extradition
    law and  [one that] has  been embodied  either explicitly  or
    implicitly  in  all prior  extradition  treaties  between the
    United States and Great Britain."  Brauch v. Raiche, 
    618 F.2d 843
    , 847 (1st  Cir. 1980).   Article III,  in relevant  part,
    provides that:
    Extradition shall be granted  for an
    act   or  omission  the  facts  of  which
    disclose  an offense  within  any of  the
    descriptions   listed  in   the  Schedule
    annexed to this Treaty . . . or any other
    offense,   if:   (a)   the   offense   is
    punishable under the laws of both Parties
    by   imprisonment   or   other  form   of
    detention  for more than  one year  or by
    the death penalty . . . .
    Treaty, art. III(1).   The annexed Schedule lists twenty-nine
    general crimes, including bribery, the crime of which Lui  is
    accused.  See Treaty, Schedule, No. 23.
    Article  V  contains various  affirmative defenses,
    including the  "political offense"  exception.  As  a general
    -23-
    23
    matter, the  political offense  exception "is now  a standard
    clause in almost all  extradition treaties of the world."   I
    Bassiouni, supra, at 384.  The political offense exception in
    the Treaty  prohibits extradition where "(i)  the offense for
    which extradition  is requested is regarded  by the requested
    Party as one  of a  political character; or  (ii) the  person
    sought proves  that the  request for  his extradition has  in
    fact  been  made with  a view  to try  or  punish him  for an
    offense of a political character."  Treaty, art. V(1)(c).
    The Supplementary Treaty  narrows the  availability
    of this political  offense exception.   It lists  a range  of
    crimes -- all crimes  of violence -- that may not be regarded
    as  political  offenses  for   the  purpose  of  raising  the
    political offense exception.   See Supplementary Treaty, art.
    1.    The Supplementary  Treaty  also  offers an  affirmative
    defense to fugitives  sought for crimes  of violence who,  by
    virtue  of its article 1,  are unable to  raise the political
    offense exception.  See Supplementary Treaty, art. 3(a), (b).
    Such a fugitive may block extradition by establishing:
    by  a preponderance of  the evidence that
    the request for  extradition has in  fact
    been made  with a  view to try  or punish
    him on  account  of his  race,  religion,
    nationality,  or  political opinions,  or
    that   he   would,  if   surrendered,  be
    prejudiced  at  his  trial  or  punished,
    detained  or  restricted in  his personal
    liberty by reason  of his race, religion,
    nationality or political opinions.
    Id. art. 3(a).
    -24-
    24
    The procedural requisites of an extradition request
    are specified in article VII of the Treaty.  The request must
    be accompanied by, inter alia, a description of the fugitive,
    a statement of facts of the offense, and the text  of the law
    under which  he is charged.   See Treaty, art. VII  (2).  For
    accused  (as opposed  to  already  convicted) fugitives,  the
    request must also  include a valid  arrest warrant and  "such
    evidence  as, according to  the law  of the  requested Party,
    would justify his committal for trial if the offense had been
    committed in the territory  of the requested Party, including
    evidence  that the person requested is the person to whom the
    warrant of arrest refers."  Id. art. VII(3).15
    Article XII contains the "specialty" requirement, a
    common feature  of extradition  treaties.  Specialty  has two
    basic components.   First, the  requesting state may  not try
    the fugitive for any crimes other than the specific crime for
    which  extradition  was  sought  and granted.    Second,  the
    requesting state may not re-extradite the fugitive to a third
    state.  See Treaty, art. XII.
    2.  Analysis
    Both  the  district court  and  Lui  focus on  four
    Treaty   provisions   in  concluding   that  the   Treaty  is
    inapplicable to  Lui.  See  Lui Habeas, --- F.  Supp. at ---,
    15.  Article IX(1), in turn, states that extradition shall
    not be granted if the evidentiary showing required by article
    VII(3) is not made by the requesting party.
    -25-
    25
    
    1997 WL 37477
    ,  at *5-*7.   We  address these  provisions in
    turn,  concluding that the obligation of the United States to
    extradite Lui, specified in  article I of the Treaty,  is not
    undermined  by any of these provisions.  We base our analysis
    on  the plain  language  of the  Treaty.   United  States  v.
    Alvarez-Machain, 504 U.S 655, 663 (1992); Sumitomo Shoji Am.,
    Inc. v. Avagliano, 
    457 U.S. 176
    , 180 (1982).  Underlying this
    analysis  is the court's awareness of the limited role of the
    judiciary in extradition proceedings.
    The Warrant Requirement
    The   district   court   understood   the   warrant
    requirement  of  article  VII(3)  to  serve  the  purpose  of
    permitting "the requested sovereign  to know that the relator
    has been accused . . . pursuant to the laws of the requesting
    sovereign,  and  that  he  will  be  tried  and  punished  in
    accordance  with that sovereign's laws."   Lui Habeas, --- F.
    Supp.  at  ---, 
    1997 WL 37477
    ,  at *6.    In this  case, the
    district court  reasoned, since  Lui would  not  be tried  in
    accordance  with the  present  Hong Kong  regime's laws,  the
    warrant requirement was not met.  
    Id.
    There is nothing in the language of article VII(3),
    or  the rest of article VII, which indicates that the warrant
    requirement serves  the greater function attributed  to it by
    the district court.   Indeed, the warrant requirement appears
    to do nothing  more than to help the judicial  officer in the
    -26-
    26
    requested country to confirm  that there are in  fact charges
    properly  pending  against  the  relator  in   the  requested
    country, and that the relator  is actually the person sought.
    It does  not authorize  the investigation which  the district
    court  envisioned,   and  indeed  such  an  investigation  is
    foreclosed  by  the  rule  of  non-inquiry.    A warrant  was
    provided  by the Hong Kong authorities here, and Lui does not
    attack its validity or authenticity.  The warrant requirement
    was plainly satisfied.
    The Dual Criminality Requirement
    The  district court  understood the purpose  of the
    dual criminality requirement, as stated in article III of the
    Treaty, to be  "to provide the  requested sovereign with  the
    opportunity to examine the  substantive law of the requesting
    sovereign in the context of the Treaty."  Lui Habeas,  --- F.
    Supp. at  ---, 
    1997 WL 37477
    ,  at *6.  The  court stated that
    the  requirement  serves  to  "underscore[]  the  expectation
    running through the Treaty that [Lui] is to be tried, judged,
    and punished in  accordance with the  laws of the  requesting
    sovereign."  
    Id.
    There  is nothing in the text of article III of the
    Treaty  that supports  this  sweeping conclusion.   The  dual
    criminality requirement, by its  plain terms, is satisfied if
    the  crime of  which the  relator is  accused appears  on the
    annexed Schedule  or is  punishable in  both countries by  at
    -27-
    27
    least  one year's  imprisonment.   Bribery,  as noted  above,
    appears on the annexed Schedule.
    The purpose of the dual criminality requirement  is
    simply to ensure that extradition is granted only for  crimes
    that are regarded as  serious in both countries.   See United
    States v. Saccoccia, 
    58 F.3d 754
    , 766 (1st Cir.  1995) ("The
    principle  of dual  criminality dictates  that, as  a general
    rule, an extraditable offense must be a serious crime (rather
    than a mere peccadillo) punishable under the criminal laws of
    both   the  surrendering   and   the   requesting   state.");
    Restatement  (Third)  of the  Foreign  Relations  Law of  the
    United States   476, cmt. d (1987); id.   475, cmt. c.
    The dual criminality requirement is satisfied here.
    The Political Offense Exception
    The district  court also relied on  article 3(a) of
    the Supplementary  Treaty,  which, it  stated,  requires  the
    judicial officer  "to examine the reasons  for the requesting
    sovereign's  desire to try and  to punish the  relator."  Lui
    Habeas, --- F. Supp. at  ---, 
    1997 WL 37477
    , at *6.   In this
    case, stated  the district  court, article  3(a) "underscores
    again   the  Treaty's   requirement   and  expectation   that
    extradition  . .  .  may not  take  place if  the  requesting
    sovereign  .  . .  is unable  to try  and  punish Lui  in the
    relatively few days left before its reversion to China."  
    Id.
    -28-
    28
    The  Supplementary Treaty  article 3(a)  defense is
    simply inapplicable here.  Supplementary Treaty  article 3(a)
    describes  a defense  which  is available  only to  fugitives
    charged with one of the crimes specified in article 1  of the
    Supplementary Treaty,  all of  which are crimes  of violence.
    Lui's  alleged crime -- bribery -- is  not  among the  crimes
    enumerated in the Supplementary Treaty's article 1.
    Indeed,  the  very  purpose  of  the  Supplementary
    Treaty was to cabin  the political offense exception so  that
    perpetrators of  certain violent offenses  would be precluded
    from  avoiding  extradition  simply  because  their  criminal
    activity was  inspired by political motivation.   See Howard,

    .   Because this contraction of  the time-
    honored political  offense exception stirred up  a great deal
    of controversy during negotiations, a compromise position was
    ultimately  agreed  upon,  so  that  fugitives   barred  from
    invoking the political offense  defense might still claim the
    protection  of the more limited defense of article 3(a).  See
    
    id. at 1324
     (discussing  negotiating history and  legislative
    history).
    Lui properly does not claim  that he is entitled to
    the   article  V(1)(c)  political  offense  exception.16  The
    16.  Even if he had attempted to assert the political offense
    exception, he would likely have been unsuccessful since
    "[c]riminal conduct in the nature of financial
    fraud . . . traditionally has been considered outside the
    'political offense' exception."  Koskotas v. Roche, 931 F.2d
    -29-
    29
    Supplementary Treaty article 3(a) defense  was unavailable to
    him, and thus, however  much article 3(a) might ever,  as the
    district court  stated, "require[]  the court to  examine the
    reasons for  the requesting sovereign's desire to  try and to
    punish the relator," Lui Habeas, --- F. Supp. at ---, 
    1997 WL 37477
    , at *6, it certainly does not do so here.
    Moreover,  article 3(a) allows the judicial officer
    to  make  only  a  narrowly  circumscribed  inquiry.    "[A]n
    extradition target  must establish by a  preponderance of the
    evidence that, if  he were surrendered,  the legal system  of
    the requesting country would treat him differently from other
    similarly situated individuals because of his race, religion,
    nationality,  or political  opinions."   Howard, 
    996 F.2d at 1331
    .   Lui made no  such showing of  discrimination, and the
    district court, in making its own predictions about the post-
    reversion justice  system in  Hong Kong, exceeded  the narrow
    inquiry permitted by article 3(a).
    The Rule of Specialty
    The   district   court   understood  the   Treaty's
    specialty provision  to signify that "the  Treaty allows only
    for extradition for  offenses that can be  tried and punished
    by the requesting sovereign."  Lui Habeas, --- F. Supp. at --
    -, 
    1997 WL 37477
    , at *6-*7.  Because the specialty obligation
    cannot  be enforced  by  the United  States after  reversion,
    169, 172 (1st Cir. 1991) (citing cases).
    -30-
    30
    reasoned  the  district court,  article  XII  is violated  ab
    initio, and Lui cannot be extradited.  Id. at *7.
    The rule of specialty literally has no  application
    here.   The rule has two basic requirements: that the relator
    be tried  for the crimes  charged in the  extradition warrant
    and that the relator not be re-extradited to another country.
    There is no claim that either of these is violated.   Indeed,
    as the district court properly recognized, Lui is not arguing
    that  the reversion  itself would  constitute a de  facto re-
    extradition  from  Hong Kong  to  China in  violation  of the
    specialty provision.  Lui  Habeas, --- F. Supp. at  ---, 
    1997 WL 37477
    , at *12 n.15; see also Oen Yin-Choy v. Robinson, 
    858 F.2d 1400
    , 1403-04 (9th Cir. 1988).
    The essence of Lui's  argument is rather different:
    it is that  the fact that he cannot be  tried and punished by
    the   same  government  which   gave  the  Treaty  assurances
    contravenes the rationale behind the specialty provisions and
    so undermines confidence that  this is the result the  Senate
    intended  in  giving  its consent.    The  responses to  that
    argument  are largely those outlined at the beginning of this
    opinion.   We add only our thoughts directed to the specialty
    clause itself.
    If Lui's position were correct,  the enforceability
    of  many extradition treaties to which the United States is a
    party would be thrown into grave doubt.  Regimes come and go,
    -31-
    31
    as, indeed, do  states.   Moreover, 18 U.S.C.    3184,  which
    defines  the role of  the courts in  the extradition process,
    gives  no discretion  to the  judicial officer  to refuse  to
    certify extraditability  on the ground that  a treaty partner
    cannot  assure  the requested  country  that  rights under  a
    treaty  will be enforced or protected.  See Saccocia, 
    58 F.3d at 766-67
    .
    The Ninth Circuit, writing in 1988, also rejected a
    similar argument made by a fugitive who fought extradition by
    arguing that the United States would be unable to compel Hong
    Kong's  compliance  with  the  specialty  obligation because,
    although  he  would  face  trial in  the  Crown  Colony,  his
    imprisonment might extend past the reversion date.  "Were the
    Treaty to be interpreted  as [the fugitive] asks, extradition
    to  Hong Kong  would be  the exception  rather than  the rule
    because it would  be limited in practice only to extraditions
    for crimes which could be punished for a term expiring before
    the  reversion date."    Oen  Yin-Choy,  
    858 F.2d at 1404
    .
    Indeed,  if we  interpreted the  specialty provision  in this
    way,  we  would  be  forced  to  conclude  that  any  relator
    extradited from the United  States to Hong Kong at  any point
    since  the signing of the Joint Declaration, was, if he faced
    a term of imprisonment upon conviction that could conceivably
    extend  past  the date  of reversion,  sent  to Hong  Kong in
    violation of the Treaty.
    -32-

    Of course,  Lui may express his  concerns about the
    post-reversion  enforceability of specialty  to the Secretary
    of State, who, in her discretion, may choose not to surrender
    him.    We note  that the  newly  signed, as  yet unratified,
    extradition treaty  between the  United States and  the HKSAR
    provides that  specialty protection "shall apply  to fugitive
    offenders who have been surrendered between the parties prior
    to the  entry into  force" of  the new  treaty.  New  Treaty,
    arts.  16, 20.    It is  not  the role  of  the judiciary  to
    speculate about the  future ability of  the United States  to
    enforce treaty obligations.
    III.
    Lui   also  challenges  the  determination  of  the
    magistrate  judge that  there was  probable cause  to believe
    that  Lui had  violated Hong Kong  law on  eight of  the nine
    charges in the warrant.  Although the district court declined
    to review this issue, we do reach it.
    Lui  protests  that we  lack  power  to reach  this
    issue,  and that  we must  remand to  the district  court for
    further findings.   However, the issue was fully  briefed and
    argued  to the district court.  The record is complete.  This
    is  a habeas corpus appeal,  in which the  district court was
    not  the fact finder but had  only a review function over the
    findings  made by the magistrate  judge.  The  function to be
    exercised by  the district  court is  more akin to  appellate
    -33-
    33
    review,  and is  done  on the  same record  as is  before us.
    Under these circumstances, the  district court had no greater
    institutional competence to perform  this review task than do
    we.  That the district court declined to reach the issue does
    not deprive us of the power to do so.
    While it is true that, as a general matter, federal
    courts of appeals do  not rule on  issues not decided in  the
    district  court,  Singleton    v. Wulff,  
    428 U.S. 106
    , 120
    (1976), we do have  discretion to address issues not  reached
    by the district court when the  question is essentially legal
    and the record is complete.  Quinn v. Robinson, 
    783 F.2d 776
    ,
    814 (9th Cir. 1986); cf. Howard, 
    996 F.2d at 1329
     ("That the
    district court failed to afford plenary review on this aspect
    of  the  case  does  not mean  that  we  must  remand . . . .
    Rather, because the  question is  quintessentially legal  and
    this court  is  fully  capable of  deciding  it  without  any
    further development of the record, we can  simply address and
    resolve it.")  (citations omitted).   Such is the  case here.
    We have before us the parties' memoranda on probable cause to
    the  district court and the  magistrate judge as  well as the
    completed evidentiary record.   In the interest of conserving
    judicial resources and mindful of the policy that extradition
    matters  be  handled  expeditiously,  we see  no  reason  for
    -34-
    34
    further delay.17   Cf. Fernandez v.  Phillips, 
    268 U.S. 311
    ,
    312   (1925)   (Supreme   Court   reviews    probable   cause
    determination   of   judge  certifying   extradition  without
    intermediate court passing on the question).
    The  traditional  formulation  is  that,  on habeas
    corpus  review of  a  certification  of extraditability,  the
    court only  examines  the magistrate judge's determination of
    probable cause to see  if there is "any evidence"  to support
    it.  Fernandez, 
    268 U.S. at 312
    ; see also Sidali v. INS, ---
    F.3d  ---,  ---, 
    1997 WL 74506
    , *9 (3d  Cir. 1997); Then  v.
    Melendez, 
    92 F.3d 851
    , 854 (9th Cir. 1996).  This circuit has
    interpreted  the  "any  evidence" standard  quite  literally,
    conducting a  fairly deferential  review of  the magistrate's
    findings.  See Koskotas v. Roche, 
    931 F.2d 169
    , 176 (1st Cir.
    1991); United  States v.  Manzi, 
    888 F.2d 204
    , 205 (1st Cir.
    1989);  Brauch, 
    618 F.2d at 854
    ; Greci v.  Birknes, 
    527 F.2d 956
     (1st Cir. 1976).
    Recently,  some  other   appellate  courts,   while
    retaining  the  traditional   formulation,  have   apparently
    17.  There is no unfairness to Lui.  He has had full
    opportunity to address the issue of whether there is probable
    cause for extradition before the magistrate judge and full
    opportunity to address the magistrate judge's determination
    before the district court.  In the extradition proceedings
    before the magistrate judge, Lui filed a 45 page memorandum
    on the probable cause issue accompanied by a copious
    appendix.  He also filed motions to exclude certain of the
    government's evidence, called witnesses, and presented both
    live testimony and testimony by affidavit.
    -35-

    engaged in a more  rigorous review of the  evidence presented
    before the judicial officer, thus raising questions about the
    actual content  of the "any  evidence" standard.   See, e.g.,
    Sidali,   --- F.3d at ---,  
    1997 WL 74506
    , at  *9; Ludecke v.
    Marshal,  
    15 F.3d 496
    ,  497-98 (5th  Cir.  1994); Peters  v.
    Egnor,  
    888 F.2d 713
    , 717-18  (10th Cir. 1989).   The Supreme
    Court  last addressed  the scope  of a  court's  authority on
    habeas corpus review of a finding of extraditability in 1925,
    when  it said that "the alleged fugitive from justice has had
    his hearing" and  that "habeas  corpus is  available only  to
    inquire"  into a very limited list of issues.  See Fernandez,
    
    268 U.S. at 312
    .   The existence of "any  evidence warranting
    the finding  that there was reasonable ground  to believe the
    accused  guilty"  was  one  of only  three  issues  that  the
    Fernandez court said might  permissibly be reached on habeas.
    
    Id.
       At  that time, the scope of habeas corpus review of all
    proceedings was  very limited, and  Fernandez's strictures on
    review in extradition  proceedings, including the deferential
    "any evidence"  standard, may  simply reflect that  generally
    narrower  view of the  writ.  See In  re Extradition of Burt,
    
    737 F.2d 1477
    , 1484 (7th Cir. 1984) ("[T]he broad language of
    Fernandez,  which on  its face would  appear to  restrict the
    scope of inquiry here,  must be construed 'in the  context of
    its  time and in the context of subsequent development of the
    scope  of habeas corpus review.'" (citation omitted)).  Since
    -36-
    36
    1925,  and until the enactment of the AEDPA in 1996,18 habeas
    corpus in  other contexts  has expanded to  become a  "second
    look" at most substantive  and procedural issues.  Similarly,
    courts  reviewing  certifications  of extraditability,  while
    continuing to cite Fernandez, have actually engaged in review
    of issues  beyond those enumerated  by the  Supreme Court  in
    1925.  See  Kester, Some Myths  of United States  Extradition
    Law, 
    76 Geo. L.J. 1441
    , 1473  (1988); see  also 4 Abbell  &
    Ristau,  supra,   13-3-6,  at 255-57.  Thus,  it is  arguable
    that the "any evidence" standard is  an anachronism, and that
    this  court should engage in  a more searching  review of the
    magistrate's probable cause findings.
    There is no reason to predict a resolution of  this
    issue  here.  Whatever the prism through which this record is
    reviewed, ranging from  a strictly  construed "any  evidence"
    standard to  de  novo  review, our  conclusion  is  that  the
    government has met its burden.
    The purpose  of  the  evidentiary  portion  of  the
    extradition  hearing  is  to  determine  whether  the  United
    States, on behalf of  the requesting government, has produced
    sufficient  evidence  to hold  the  person  for trial.    The
    standard of  sufficiency is  derived from United  States law,
    including the  Treaty between the  United States and  the UK.
    18.   Antiterrorism and Effective Death Penalty Act
    ("AEDPA"), Pub. L. No. 104-132,

    Under 18 U.S.C.    3184, the judicial officer  must determine
    whether the evidence of criminality is "sufficient to sustain
    the  charge under  the  provisions of  the  proper treaty  or
    convention."  The Treaty requires that:
    Extradition shall be granted only if
    the   evidence    be   found   sufficient
    according  to the  law  of the  requested
    Party . . . to justify  the committal for
    trial of the person sought if the offense
    of which he is accused had been committed
    in the territory of the requested Party .
    . . .
    Treaty, art.  IX(1).  "United States  courts have interpreted
    this provision in similar treaties as requiring a  showing by
    the requesting party  that there is probable cause to believe
    that the accused has committed the charged  offense."  Quinn,
    
    783 F.2d at 783
      (separate opinion of Reinhardt, J.)  (citing
    cases).  The Supplementary Treaty defines probable cause:
    Probable  cause means  whether there
    is sufficient evidence  to warrant a  man
    of  reasonable  caution  in   the  belief
    that . . . an offense  has been committed
    by the accused.
    Supplementary Treaty, art. 2.   The actual trial, if  any, is
    in  the foreign  court,  and it  is not  the  purpose of  the
    extradition  hearing to  determine  whether the  evidence  is
    sufficient  to justify conviction.   Thus it  is the probable
    cause determination which is subject to our review.
    There is no  dispute that payments  of over HK  $21
    million (approximately US $3  million) and unsecured loans of
    HK $10 million  (approximately US $1.4 million)  were made to
    -38-
    38
    Lui, that the payments  were made into foreign  bank accounts
    in Lui's name, and  that the payments were not  made directly
    by check but  through a series of steps which  made them more
    difficult  to trace.    There is  also  no dispute  that  the
    payments  were  made on  the dates  charged.   The  timing is
    significant.  The payments  coincided with the knowledge that
    Lui was being  considered as Director  of Exports for  BAT-HK
    and with his  appointment to  that position in  1992.19   The
    loans  were  made  within three  days  of  Lui's  leaving his
    employment  at  Brown &  Williamson and  BAT-HK.   It  is not
    contested that BAT-HK was the major supplier of cigarettes to
    GIL and WWC, that Brown  & Williamson prohibits its employees
    from  accepting "inducements"  from those  with whom  it does
    business and requires disclosure  statements to be completed,
    and that Lui failed to disclose any of these payments  on his
    disclosure form.   The dispute between the government and Lui
    is basically over the purpose of these payments.
    Two  competing theories  explaining the  purpose of
    the payments were  presented to  the magistrate  judge.   The
    government argued  that the  payments were bribes.   Although
    Lui  had no  burden to  produce any evidence  at all  and the
    burden  of  showing probable  cause  rested  entirely on  the
    government, Lui did present an  explanation for the loans and
    19.  The one exception to this was the October 1988 payment
    alleged in Count II, as to which the magistrate judge found a
    lack of probable cause.
    -39-
    39
    payments,  primarily  in  the  affidavit  of  Hung  Wing  Wah
    ("Hung"),  a former GIL director and sole proprietor of GIL's
    subsidiary,  WWC.20  In essence, Hung said that, in or around
    1987, prior  to Lui's employment with Brown  & Williamson, he
    and Lui  first began discussing "cigarette business matters."
    Hung  stated that  these  discussions eventually  led to  the
    establishment of a profitable  business relationship in which
    Hung  purchased  Japanese cigarettes  and  resold  them at  a
    profit for  the account of  Chen Ying-Jen ("Chen"),  a former
    GIL principal.  The  payments to Lui's foreign  bank accounts
    were filtered through Chen's account.
    Hung stated  he was told  by Chen that,  because of
    the   substantial   profits   generated   by   the   business
    relationship Lui had been  instrumental in establishing, Chen
    had agreed to pay  Lui for his assistance and  would continue
    paying Lui as  long as the relationship continued to generate
    such substantial profits.  Hung indicated that  the sums paid
    to  Lui bore  a reasonable  relationship to the  magnitude of
    Chen's profits.  And finally, Hung  stated that the unsecured
    short term  loans  had been  made to  Lui so  that Lui  could
    invest  in the  then-booming Hong  Kong stock  market.   Hung
    20.  Lui chose not to testify on his own behalf, as was his
    prerogative.  The magistrate judge properly excluded the
    polygraph evidence offered by Lui to corroborate his
    testimony.  The polygraph evidence was not relevant, there
    being no such testimony in evidence to corroborate.  Whether
    it would be admissible if he did testify, we do not address.
    -40-
    40
    stated  that  both the  principal  and  interest were  repaid
    shortly after the loans were made.  During the hearing before
    the magistrate judge, Lui's  counsel indicated that Lui would
    testify, and described  what that testimony  would be.   This
    description  matched  the  testimony  given  by  Hung.    Lui
    ultimately declined to testify.
    Lui  argued  that  the  government's  evidence  was
    insufficient  to support  an  inference of  bribery and  that
    there  was,  in  any event,  an  innocent  explanation.   The
    government argued  that the undisputed  facts were sufficient
    to  establish probable  cause, and  that the  explanation was
    inherently implausible.   In addition, the government argued,
    it  had  two "smoking  gun"  statements  directly saying  the
    payments  were bribes.  We return to these two statements and
    Lui's attack on them later.
    The magistrate judge concluded that the explanation
    proffered  by  Lui's  counsel  --  "to  the effect  that  the
    payments represented a gratuitous gesture of gratitude by one
    of   GIL's  former   principals  for   Lui's   assistance  in
    introducing him to a supplier of Japanese cigarettes in 1987,
    some six years  before the  last payments were  made" --  was
    inherently implausible.   Lui Extradition,   
    939 F. Supp. at 955
    .21    The implausibility  of  the  explanation does  give
    21.  The statement in the magistrate's opinion that Lui
    adduced only counsel's argument and not explanatory evidence,
    Lui Extradition, 
    939 F. Supp. at 955
    , is obviously an
    -41-
    41
    credence to the  government's theory.   See United States  v.
    Burgos, 
    94 F.3d 849
    , 867 (4th Cir. 1996)  (implausible tales
    to  the   finder  of  fact   can  rationally  be   viewed  as
    circumstantial  evidence of guilt).  Without consideration of
    the two  "smoking gun"  statements, the magistrate  judge was
    fully warranted in finding probable cause.
    In addition,  the two statements, which  Lui argues
    were  inadmissible,  were properly  admitted at  the probable
    cause stage  of the extradition hearing and further support a
    finding of probable cause.
    The  first  statement   was  given  to   Hong  Kong
    investigators  in July 1994 by Chui, one of Lui's alleged co-
    conspirators.   Chui was one  of the principals  of GIL until
    April 1993.   In his  statement, Chui implicated  himself and
    other principals  of GIL in a scheme  to bribe Lui and others
    to  secure favorable allocations  of cigarettes  from BAT-HK.
    According to Chui, GIL  began paying bribes to Lui  when they
    first   anticipated  that  Lui  might  eventually  become  an
    important  BAT-HK   decisionmaker.    Chui  was  murdered  in
    Singapore nine months after giving this statement.
    The second  statement was made by  Francis McNamara
    Haddon-Cave, who worked with  Chui.  Haddon-Cave testified in
    Hong  Kong  in October  1995 at  a  hearing to  determine the
    oversight.  Among other items, the Hung Wing Wah affidavit
    was admitted into evidence and considered by the magistrate
    judge.
    -42-
    42
    sufficiency of the  evidence to commit  one of Lui's  alleged
    co-conspirators  for trial on a charge of conspiracy to bribe
    Lui.  Haddon-Cave testified that he was hired by Chui to work
    as  a consultant for GIL  and began working  there in October
    1992.   One of  Haddon-Cave's responsibilities was  to foster
    relationships between  GIL and  major suppliers  like BAT-HK.
    Haddon-Cave testified  that Chui  told him in  Lui's presence
    that Lui  was "our man" and an important link with GIL.  Lui,
    then  BAT-HK's Director of Exports, did not deny it.  Haddon-
    Cave further testified that later, outside of Lui's presence,
    Chui  told him  that Lui  was "on  the take"  and had  become
    wealthy as a result of the payments that distributors made to
    him to secure favorable allocations of cigarettes.
    The  framework  for  determining  admissibility  of
    evidence  here is  determined  by the  Treaty  itself and  by
    United   States  legal   rules  governing   admissibility  in
    extradition proceedings.      Pursuant  to  federal  statute,
    documents offered as evidence in an extradition hearing:
    shall   be   received  and   admitted  as
    evidence  . . . for  all the  purposes of
    such  hearing if  they shall  be properly
    and  legally  authenticated   so  as   to
    entitle them  to be received  for similar

    18  U.S.C.    3190.22   Proof of  such authentication  is the
    certificate  of the principal  diplomatic or consular officer
    of the United States  resident in such foreign country.   
    Id.
    Additionally, article VII(5) of  the Treaty provides that any
    evidence given upon oath or affirmation "shall be received in
    evidence in  any proceedings for  extradition" if it  is duly
    authenticated.   Treaty, art.  VII(5).  Both  the Haddon-Cave
    testimony  and  the  Chui  statement meet  this  authenticity
    requirement  and  were  thus  admissible  at the  extradition
    hearing by the terms of the relevant statute and treaties.
    Lui argues nonetheless that the two statements were
    improperly  admitted because  they would  be  inadmissible at
    trial under  Hong Kong law.  Lui argues that it is inherently
    unfair to certify  that he  is extraditable on  the basis  of
    evidence that  would be inadmissible  in the  court where  he
    would  face trial.  He  also argues that  failure to consider
    the  Hong  Kong  High  Court's  declaratory  judgment  (later
    reversed) that the Chui statement would be inadmissible would
    evince great disrespect for the judicial system of Hong Kong.
    Both of these arguments are misplaced.
    22.  Lui does not rely on the language of 18 U.S.C.   3190.
    Most courts reviewing the language have concluded that   3190
    requires only that the evidence meet any authentication
    requirement imposed by a foreign tribunal, not that it be
    admissible, much less that it be admissible at trial.  See
    Oen Yin-Choy, 
    858 F.2d at 1406

    In probable cause hearings under  American law, the
    evidence taken need not  meet the standards for admissibility
    at  trial.  Indeed, at a preliminary hearing in federal court
    a "finding of  probable cause  may be based  upon hearsay  in
    whole or in part."  Fed. R. Crim. P. 5.1(a).  This is because
    a "preliminary hearing  is not  a minitrial of  the issue  of
    guilt," Coleman v.  Burnett, 
    477 F.2d 1187
    , 1201 (D.C.  Cir.
    1973); rather,  "its  function is  the  more limited  one  of
    determining whether probable cause exists to hold the accused
    for trial."   Barber v. Page,  
    390 U.S. 719
    , 725  (1968).  An
    extradition   hearing   similarly   involves  a   preliminary
    examination of the evidence and is not a trial.   Charlton v.
    Kelly,  
    229 U.S. 447
    , 461  (1913); Romeo v.  Roache, 
    820 F.2d 540
    ,  544 (1st Cir. 1987).   An extradition  hearing does not
    require  a higher standard of evidence  than a probable cause
    hearing.    The special  and  limited  nature of  extradition
    hearings  is  manifested  in  a  more  lenient  standard  for
    admissibility  of evidence.    Neither the  Federal Rules  of
    Criminal Procedure, see  Fed. R. Crim.  P. 54(b)(5), nor  the
    Federal  Rules of  Evidence,  see Fed.  R. Evid.  1101(d)(3),
    apply to extradition hearings.   The evidence may coU.S. 309,
    317 (1922).    So  American domestic law has already resolved
    against  Lui  any   claim  that  there  is   a  violation  of
    Constitutional rights from the admission of hearsay  evidence
    -45-

    at  a probable cause hearing  which would not  be admitted at
    trial.
    Under Hong Kong law, the Haddon-Cave statement  and
    the Chui statement present separate and distinct issues.  The
    Haddon-Cave statement was ruled inadmissible at the Hong Kong
    trial of Chong Tsoi-Jun ("Chong"), an alleged co-conspirator,
    on an objection that  it was not  made in furtherance of  the
    conspiracy.
    As to  the Chui statement,  a Hong Kong  High Court
    judge   issued  a   declaration   that  the   statement   was
    inadmissible  hearsay.   On appeal,  the  Hong Kong  Court of
    Appeal vacated this ruling, finding  that Lui's request for a
    declaratory  judgment was  not justiciable  in the  Hong Kong
    courts, but  that even if it  were, the judge's grant  of the
    declaration  would be an abuse  of discretion.   The Court of
    Appeal reasoned that  the issue of  the admissibility of  the
    Chui statement in the extradition proceeding was a matter for
    the United States court to decide.  The court noted, however,
    that the  parties agreed that the  statement was inadmissible
    hearsay under  Hong  Kong law.   In  light of  the Hong  Kong
    court's  statement   that  the  admissibility  of   the  Chui
    statement in  the extradition  hearing  is a  matter for  the
    United  States court  to decide,  admission of  the statement
    into evidence  cannot be viewed as a sign of disrespect for a
    sister court.

    The focus on admissibility is, we think, misplaced,
    both  based  on  these  facts and  on  larger,  institutional
    concerns about the operation  of habeas corpus in extradition
    certifications.   While in Manzi we  "recognized that serious
    due process concerns may merit review beyond the narrow scope
    of inquiry  in extradition proceedings," there  is no serious
    due process issue here.  See Manzi, 
    888 F.2d at 206
    ; see also
    Koskotas,  
    931 F.2d at 174
    ; cf.  Burt,  
    737 F.2d at 1481
    ;
    Gallina,  
    278 F.2d at 78
    .    Lui's  liberty  interests  are
    protected  by  the very  existence  of  "an unbiased  hearing
    before an independent judiciary."   In re Kaine, 55  U.S. (14
    How.) 103 (1852).
    Inherent  in the  probable  cause  standard is  the
    necessity  of  a  determination  that the  evidence  is  both
    sufficiently reliable and of sufficient weight to warrant the
    conclusion.    The  probable  cause standard  does  not  even
    require   that  the   government  make   its  showing   by  a
    preponderance of  the evidence.  But neither is it toothless.
    All evidence does not  have the same importance even if it is
    authentic and admissible.  For example, a confession obtained
    by duress is inherently unreliable  and would be given little
    weight even  if the confession were authenticated.   See Gill
    v. Imundi, 
    747 F. Supp. 1028
    , 1042-47 (S.D.N.Y. 1990).   The
    reliability of  the evidence is  a factor  for the  reviewing
    court   to  consider  as  well,  and  potentially  unreliable
    -47-
    47
    evidence  may  be  accorded  reduced  weight  by  the  court.
    Restatement, supra,   478.
    No such  concerns about reliability  are implicated
    here.    First,   the  statements  themselves   were  neither
    involuntary  nor  obtained under  questionable circumstances.
    Further, the  Hong  Kong  courts  did not  rule  that  either
    statement  was   untrue  or  otherwise  cast   doubt  on  the
    statements'   credibility.     Each  statement   was  thought
    inadmissible in  Hong Kong on grounds  pertaining to hearsay.
    The Haddon-Cave statement was deemed inadmissible because  it
    did not meet one  of the requirements for admissibility  of a
    co-conspirator's statement.  The  Chui statement was  thought
    inadmissible because  the declarant was dead.   The Hong Kong
    government alleges  that Chui was involved  in the conspiracy
    until  he became a government informant  and witness and that
    he was murdered in order to prevent him from testifying.  GIL
    directors,  including  Hung  and  Chong,  allegedly  tried to
    dissuade  Chui from cooperating with  the ICAC.   We need not
    reach  the  issue of  whether the  statement of  a declarant,
    murdered  to keep him from testifying, might be admissible at
    a criminal trial in  the United States, cf. United  States v.
    Houlihan,  
    92 F.3d 1271
       (1st  Cir.  1996),  whatever  the
    consequence   of   these   facts   under   Hong   Kong   law.
    Nevertheless,  we note that the Chui  statement might well be
    admissible  under United  States law  as a  statement against
    -48-
    48
    interest.  See Fed. R. Evid. 804(b)(3).  The magistrate judge
    correctly ruled that the two statements were not unreliable.
    One final  argument need not  detain us long.   Lui
    argues, from  his counsel's tactical decision  not to present
    his  testimony  at  the  extradition  hearing,  that  he  was
    precluded  from testifying.   He  argues that  the magistrate
    judge  drew an  unfavorable  inference, in  violation of  his
    Fifth  Amendment rights, from  his failure  to testify.   The
    argument  misapprehends what happened.   The magistrate judge
    did no such  thing.   Lui presented testimony  from Hung  and
    five  other   affiants,  as  well  as   argument  of  counsel
    attempting to explain the payments and loans.  The magistrate
    judge  disbelieved  the explanation,  as  it  was within  his
    discretion to do.  There is nothing in this objection.
    For these  reasons we  reverse the grant  of habeas
    corpus  by the  district court.   We  continue in  effect the
    requirement that Lui be held without bail.  If Lui  wishes to
    file a petition for rehearing and/or a petition for rehearing
    en banc with  this court,  he must do  so within 14  calendar
    days.  See Fed.  R. App. P. 40(a) &  35(c).  We stay,  in any
    event, delivery  of the  certification of  extraditability to
    the  Secretary of State during this 14 calendar day period to
    permit  Lui to  seek relief  from the  United States  Supreme
    Court.
    So ordered.
