    SELYA,  Circuit Judge.
    issues of first impression in extradition law generally and, more
    specifically, regarding  a rather distinctive  extradition treaty
    in  force between  the United  States and  the United  Kingdom of
    Great  Britain and Northern  Ireland (U.K.).   We must determine,
    inter  alia, (1)  whether, under  the treaty,  the second  of two
    successive  appeals from  a certification  of  extraditability is
    within our  jurisdiction;  (2) if  so,  what standard  of  review
    governs such appeals; (3) whether the treaty alters the venerable
    rule  of  noninquiry; and  (4)  if  so, to  what  extent.   After
    grappling with  these, and other, matters,  we eventually address
    the merits of the  appeal and conclude that the  determination of
    extraditability must stand.
    I.  BACKGROUND
    The seeds of  this appeal  were sown on  June 1,  1991,
    when  a  policeman discovered  the  mutilated  body of  Catherine
    Elizabeth Ayling, a young white female, in the trunk  of a rental
    car  abandoned   at   England's  Gatwick   Airport.     Suspicion
    immediately  centered  on   respondent-appellant  Curtis   Andrew
    Howard,  a  United  States  citizen.    Charges  were  preferred.
    Because  Howard   had  returned  to  his   native  land,  British
    authorities sought to extradite him.  On June 5, 1991, the United
    States Attorney  for the District of  Massachusetts requested and
    received from a federal  magistrate judge a warrant for  Howard's
    provisional arrest.  See 18 U.S.C.   3184 (1988 & Supp. II 1990);
    D. Mass. Loc. Mag. R. 1(e).  Howard was apprehended.  He appeared
    2
    for  an  extradition  hearing  before  the  magistrate  judge  on
    September 10, 1991.
    At the hearing Howard did not dispute the  existence of
    probable cause  to  believe  he had  murdered  Ayling.    Rather,
    Howard, who is black,  argued that he would be  prejudiced during
    legal  proceedings  in  the  U.K.  by  reason  of  his  race  and
    nationality, a circumstance which, if true, constituted a defense
    to  extradition under  the  relevant treaty.   See  Supplementary
    Extradition  Treaty,   June  25,  1985,  U.S.-U.K.,   art.  3(a),
    reprinted in  S. Exec.  Rep. No. 17,  99th Cong., 2d  Sess. 15-17
    (1986)  (Supplementary  Treaty).   In  support  of this  defense,
    Howard proffered evidence of flamboyant publicity surrounding his
    case,  sought to  show that  Britons would  likely  be prejudiced
    against blacks    particularly  those accused of  murdering young
    white  females   and pointed out that England's legal system does
    not  make  any provision  for  voir dire  of  prospective jurors.
    These proffers did  not sufficiently impress the magistrate:   he
    ruled  that  Howard  had  not  established  a  valid  defense  to
    extradition   and   thereupon    issued   a   certification    of
    extraditability, together with  an order of commitment.1   See 18
    U.S.C.   3184.
    1The magistrate  found that  all the basic  prerequisites to
    extradition  had been fulfilled in that the United States and the
    U.K. are parties to  an extradition treaty; a criminal  charge is
    pending against Howard  in the  U.K.; the charged  offense is  an
    extraditable crime  under the treaty;  the person charged  is the
    same  person  whom the  government  wants  extradited; an  arrest
    warrant is outstanding; and probable cause exists to believe that
    Howard committed the crime.  None of these findings are contested
    on appeal.
    3
    Howard   appealed.     The  district   court  exercised
    jurisdiction, reviewed the magistrate's findings for clear error,
    and affirmed.  See In re Howard, 
    791 F. Supp. 31
     (D. Mass. 1992).
    Howard appeals anew.
    II.  THE SUPPLEMENTARY TREATY
    Because the Supplementary  Treaty departs from accepted
    extradition protocol, we trace its origins  and spotlight its key
    provisions.
    In 1972, the United States  and the U.K. negotiated new
    terms   governing  reciprocal   extradition  from   one  nation's
    territory  of persons  accused or  convicted of  certain offenses
    committed in the other  nation.  See Extradition Treaty,  June 8,
    1972, U.S.-U.K., art. I,  28 U.S.T. 227, 229 (Treaty).  Under the
    Treaty, murder was an extraditable offense.  See 
    id.
     art. III(1).
    Nonetheless, the Treaty allowed a signatory to refuse extradition
    if it regarded  the offense  "as one of  a political  character."
    
    Id.
      art. V(c)(i).  This exception sired friction between the two
    traditional allies when federal judges in the United States began
    interpreting it to bar extradition of members of the  Provisional
    Irish Republican  Army.  See S.  Exec. Rep. No. 17,  supra, at 2;
    see also 132 Cong. Rec. 16,558-86 (1986) (collecting cases).
    To   ameliorate   this   situation,   the   signatories
    negotiated treaty  amendments aimed at eradicating  the political
    offense  exception for acts of violence.   See S. Treaty Doc. No.
    8, 99th Cong., 1st  Sess. (1985) (Proposed Supplementary Treaty);
    see  also  S. Exec.  Rep. No.  17, supra,  at  2.   However, when
    4
    President Reagan  submitted the Proposed Supplementary  Treaty to
    the Senate, seeking its advice and consent, the document received
    mixed   reviews.     See   United  States   and  United   Kingdom
    Supplementary Extradition  Treaty:   Hearings  Before the  Senate
    Comm.  on  Foreign  Relations,  99th  Cong.,  1st  Sess.  (1985).
    Following  many months  of  strident debate,  the opposing  camps
    reached  a compromise,  placing  most violent  crimes beyond  the
    political  offense exception's  reach  but  adding certain  novel
    safeguards for the  protection of potential extraditees.   See S.
    Exec. Rep. No. 17, supra, at  4-5.  On July 17, 1986, the  Senate
    ratified the  proposed treaty subject  to the addition  of these,
    and  other,  amendments.    See  132  Cong.  Rec. 16,819  (1986).
    Following approval  of  the  modified version  by  the  House  of
    Commons, instruments of ratification  were exchanged on  December
    23, 1986.  See  Supplementary Treaty, supra, reprinted at  Hein's
    No. KAV 2053; see also I.I. Kavass et al., Extradition:  Laws and
    Treaties  920.20d-h  (1979 &  Supp. 1989).    At that  point, the
    Supplementary Treaty went into force.
    An aspect  of the Senate-forged compromise  lies at the
    core  of the instant case.  As ratified, the Supplementary Treaty
    prohibits  extradition "if the person sought establishes . . . by
    a preponderance of evidence 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."  Supplementary  Treaty, art.
    3(a).  Appellant's case rests squarely upon this proviso.
    5
    III.  APPELLATE JURISDICTION
    The  Supplementary Treaty  stipulates that  the trier's
    findings with regard to an article 3(a) defense  are "immediately
    appealable  by either party to  the United States district court,
    or  court of  appeals,  as appropriate."   Id.  art.  3(b).   The
    initial question that commands  our attention concerns the extent
    of our jurisdiction under  this provision.  We raised  this issue
    at oral  argument, as a court  must when it harbors  doubts about
    the  existence of  its  subject matter  jurisdiction,  see In  re
    Recticel  Foam  Corp.,  
    859 F.2d 1000
    ,  1002  (1st  Cir.  1988)
    (emphasizing  that "a  court  has an  obligation  to inquire  sua
    sponte into  its subject matter jurisdiction"),  and directed the
    parties to furnish supplemental briefs.2
    A.  Past Practice.
    Ordinarily neither  party to an  extradition proceeding
    may challenge a decision rendered therein by direct appeal.  This
    disability developed  because the  relevant statute, 18  U.S.C.
    3184, does not  contemplate hearings by United  States courts qua
    United States courts, see In re  Mackin, 
    668 F.2d 122
    , 125-30 (2d
    Cir.   1981)  (collecting  authorities  and  tracing  history  of
    extradition proceedings), but,  instead, directs that extradition
    matters be heard by "any justice or  judge of the United States,"
    any authorized  magistrate, or certain state  judges.  Therefore,
    2It  is,  of  course,  settled that  parties  cannot  confer
    subject matter jurisdiction on a federal court by acquiescence or
    agreement.   See Insurance Corp. of Ir. v. Compagnie Des Bauxites
    De Guinee, 
    456 U.S. 694
    , 702 (1982).
    6
    an  officer who presides over such a proceeding is not exercising
    "any  part of the  judicial power of  the United States."   In re
    Kaine,  55 U.S. (14  How.) 103, 120 (1852).   Rather, the officer
    acts  in a  non-institutional capacity  by virtue  of  a "special
    authority."  In re Metzger, 46 U.S. (5 How.) 176, 191 (1847); see
    also  Shapiro  v. Ferrandina,  
    478 F.2d 894
    ,  901 n.3  (2d Cir.)
    (applying same principle to  current statutory provision),  cert.
    dismissed,  
    414 U.S. 884
      (1973);  Mackin,  
    668 F.2d at 125-30
    (same);  Jimenez v.  Aristeguieta, 
    290 F.2d 106
    ,  107 (5th  Cir.
    1961)  (same).  The officer's only tasks are to determine whether
    an   individual  is   extraditable,   and  if   so,  to   certify
    extraditability to  the ultimate decisionmaker  (the Secretary of
    State).  See 18 U.S.C.    3184, 3186 (1988 & Supp. II 1990).
    In light of this  curious arrangement, numerous  courts
    have  held that 28 U.S.C.   1291, which permits appeals of "final
    decisions of  the district courts" (emphasis  supplied), does not
    contemplate appeals from  decisions of judicial officers  sitting
    in  extradition matters.   See,  e.g., Ahmad  v. Wigen,  
    910 F.2d 1063
    , 1065 (2d  Cir. 1990); Quinn v. Robinson, 
    783 F.2d 776
    , 786
    n.3 (9th   Cir.), cert. denied,  
    479 U.S. 882
     (1986).   Given the
    absence of  any other statutory  hook on which  jurisdiction over
    such  appeals can be hung,  a putative extraditee customarily can
    challenge  an order  for extradition  only by  collateral attack,
    typically through habeas corpus.  See Collins v. Miller, 
    252 U.S. 364
    , 369 (1920); Koskotas v.  Roche, 
    931 F.2d 169
    , 171 (1st  Cir.
    1991).   By the same  token, the  government, if it  fails in  an
    7
    extradition attempt,  cannot appeal,  but  must file  anew.   See
    Mackin, 
    668 F.2d at 128
    ; Hooker v. Klein, 
    573 F.2d 1360
    , 1364-68
    (9th Cir.), cert. denied,  
    439 U.S. 932
     (1978); see  also Collins
    v. Loisel, 
    262 U.S. 426
    , 430 (1923).
    B.  Article 3(b).
    Appellant   argues   that   the  Supplementary   Treaty
    revolutionizes  this  praxis  insofar as  the  extradition target
    asserts defenses  cognizable under article 3(a).   The government
    argues the inverse, imploring that  neither the President nor the
    Senate intended to  work so  abrupt a tergiversation.   We  agree
    with appellant that the Supplementary Treaty, which has the force
    of  law, U.S.  Const. art.  VI, cl.  2, effects  a sea  change in
    established policy.
    The Supplementary  Treaty provides that a finding anent
    a  so-called  article  3(a) defense,  involving  race,  religion,
    nationality,   or  political   opinion,  "shall   be  immediately
    appealable by either  party to the United States  district court,
    or court of appeals, as appropriate."  Supplementary Treaty, art.
    3(b).  This appeal provision, which apparently finds its  genesis
    in an earlier (failed) attempt  to alter the protocol prohibiting
    direct appeals in extradition matters, see 132 Cong.  Rec. 16,599
    (1986),  is couched  in plain  language and,  in our  view, means
    precisely  what it  says.   See Sumitomo  Shoji America,  Inc. v.
    Avagliano, 
    457 U.S. 176
    ,  180 (1982) (explaining that a  treaty's
    literal language must be given effect unless patently contrary to
    the signatories'  intentions and expectations).   In crafting the
    8
    appeal  provision,  the  drafters carefully  drew  a  distinction
    between hearings held under 18 U.S.C.   3184 and appeals taken to
    courts cloaked with the judicial power of the  United States.  In
    discussing  the former,  the  document refers  to "the  competent
    judicial   authority"   who   is   "[i]n   the   United  States."
    Supplementary Treaty, art. 3(b); see also 
    id.
     arts. 2,  3(a).  By
    contrast,  in discussing  appeals,  the treaty  refers to  United
    States courts  by name.  See 
    id.
     art. 3(b).  The same distinction
    recurs in the legislative history.  See, e.g., S. Exec.  Rep. No.
    17, supra,  at 8.    That is  a significant  datum,  for, if  the
    language of a  treaty is  at all  ambiguous, courts  may look  to
    legislative   history  in   interpreting  its   provisions  under
    virtually  the  same  rules  that obtain  when  courts  interpret
    statutes.   See  Factor v.  Laubenheimer,  
    290 U.S. 276
    ,  294-95
    (1933).
    The other straws in  the interpretive wind bend  in the
    same  direction.   The Supplementary  Treaty stipulates  that the
    "Federal  Rules of  Appellate  Procedure or  Civil Procedure,  as
    appropriate, shall  govern the appeals  process."   Supplementary
    Treaty,  art.   3(b).    And,  again,   the  legislative  history
    reinforces the point, indicating  that the disputed provision "is
    not intended to  make the Federal  rules generally applicable  to
    the  extradition  hearing itself,  but only  to  the appeal  of a
    decision under article 3(a)."  S. Exec. Rep. No. 17, supra, at 8.
    In  short, the text  of article 3(b), taken  as a whole, suggests
    not only that an  appeal thereunder represents an entry  into the
    9
    federal courts  but also  that extradition  proceedings involving
    article 3 differ in  kind from those involving  only 18 U.S.C.
    3184.
    We rule, therefore, that the Supplementary Treaty marks
    a clean break from  the ancient prohibition on direct  appeals in
    extradition   matters;  where   article  3  is   implicated,  the
    Supplementary  Treaty  contemplates at  least  one  appeal as  of
    right.  Accord In re  McMullen, 
    981 F.2d 603
    , 609 (2d  Cir. 1993)
    (en banc).  Moreover, because the Supplementary Treaty explicitly
    identifies United  States courts, not judges or  justices, as the
    appellate authority,  see  Supplementary Treaty,  art.  3(b),  it
    unlocks  the  gate  which  has  historically  barred  extradition
    matters from proceeding further through the federal courts in the
    same manner as other cases.
    C.  Successive Appeals.
    Our jurisdictional  odyssey is  not yet ended.   Noting
    that article 3(b) provides  for appeals to the district  court or
    court  of  appeals,  the  government  asserted  below  that  this
    disjunctive  language restricts  the parties to  one bite  of the
    apple and rules  out successive appeals (such  as Howard essays).
    In this  court, however, the government  backtracks, appearing to
    concede that,  notwithstanding Howard's  earlier appeal,  we have
    jurisdiction over this appeal.  But, since  this point implicates
    appellate jurisdiction and is non-frivolous,  see post (Campbell,
    J.,  concurring),  we are  not at  liberty  simply to  accept the
    government's concession.  See supra note 2.  We proceed to ponder
    10
    the point.
    We  think  the  language  of article  3(b)  dictates  a
    construction antithetic to that which the government urged below.
    Because  the Supplementary Treaty  contemplates the initiation of
    extradition  proceedings  before either  a  district  judge or  a
    magistrate judge,  see S. Exec. Rep.  No. 17, supra, at  5, 6, 8,
    article  3(b)  prudently provides  for  review  by the  "district
    court, or court of appeals, as appropriate."  In other words, the
    disjunctive  "or"  is  to   be  read  not  as  an   unusual,  but
    understated, restriction  on the  number of appeals;  rather, the
    term  specifies  that the  ordinary  sequence  of appeals  should
    apply.   This conclusion is supported by the reference in article
    3(b)  to the  "appeals process,"  as well  as by  the legislative
    history.  See S. Exec. Rep. No. 17, supra, at 8.
    We will not cart  coal to Newcastle.  Not  even so much
    as  a  solitary  word  or  phrase  in  the  Supplementary  Treaty
    intimates  an intent to prohibit  successive appeals    and it is
    not   the  courts'   business  to   rewrite  a   treaty's  text.3
    Accordingly,  we  hold  that  article  3(b)  permits   successive
    appeals,  see, e.g., United States  v. Van Fossan,  
    899 F.2d 636
    ,
    637-38  (7th Cir.  1990)  (holding that,  in  the absence  of  an
    express  provision prohibiting  successive appeals,  the criminal
    misdemeanor  statute, 18  U.S.C.    3402  (1988), permits  them);
    3We  appreciate  the  force  of  the  policy  considerations
    mentioned by Judge Campbell, see post (Campbell, J., concurring),
    but  we believe that such  matters must be  left to those charged
    with negotiating, executing, and ratifying treaties.
    11
    United  States v.  Forcellati, 
    610 F.2d 25
    ,  28 (1st  Cir. 1979)
    (similar),  cert.  denied,  
    445 U.S. 944
      (1980),  to  be  given
    expedited   consideration,  however,   as  article   3(b)  itself
    provides, "at every stage."
    D.  Recapitulation.
    To sum  up, the language and legislative history of the
    Supplementary Treaty make it clear that the appeal right provided
    by article 3(b)  implicates a "decision[] of the  district court"
    within the  meaning of 28  U.S.C.   1291.   In this  sense, then,
    article  3(b)  breaks with  traditional  practice  by authorizing
    direct appeals to the  federal courts from certain determinations
    regarding  extradition.    What  is more,  the  pertinent  treaty
    provision  permits successive  appeals from a  magistrate judge's
    decision to the  district court  and thereafter to  the court  of
    appeals.    Because  that   path  was  followed  here,  appellate
    jurisdiction attaches.
    IV.  STANDARD OF REVIEW
    Having cleared the jurisdictional hurdle, we  turn next
    to appellant's  asseveration that  the district court  employed a
    faulty  standard of review.  Because this presents a purely legal
    question,  requiring  an   interpretation  of  the  Supplementary
    Treaty,  our  review is  plenary.   See,  e.g., United  States v.
    Washington,  
    969 F.2d 752
    , 754 (9th Cir. 1992), cert. denied, 
    113 S. Ct. 1945
     (1993); Quinn, 783 F.2d at 791.
    A.  Principles Governing Review.
    Determinations concerning article 3(a)  defenses "shall
    12
    be   immediately  appealable   by  either   party"  through   the
    instrumentality of  "filing a  notice of appeal."   Supplementary
    Treaty, art. 3(b).   But,  though this article  grants rights  of
    appeal,  it does  not  mention standards  of  review.   We  look,
    therefore, to first principles.
    Absent  a specific statutory directive to the contrary,
    appeals in the federal  court system are usually arrayed  along a
    degree-of-deference continuum, stretching from plenary  review at
    one  pole to  highly  deferential modes  of  review (e.g.,  clear
    error, abuse  of discretion)  at the opposite  pole.  At  the "no
    deference"  end   of   the  continuum   lie   appeals   involving
    unadulterated  questions   of  law,  the   resolution  of   which
    customarily entails de  novo review.   See, e.g., Liberty  Mutual
    Ins.  Co. v. Commercial  Union Ins. Co.,  
    978 F.2d 750
    , 757 (1st
    Cir.  1992).   At  the other  end  of the  continuum  lie appeals
    involving  straight factual  determinations,  the  resolution  of
    which customarily  entails acceptance of the  trier's judgment in
    the  absence of  palpable error.   See,  e.g., Cumpiano  v. Banco
    Santander Puerto Rico, 
    902 F.2d 148
    , 152 (1st Cir. 1990) (holding
    that appellate courts  "ought not  to upset findings  of fact  or
    conclusions  drawn therefrom unless, on the  whole of the record,
    [the appellate judges]  form a strong,  unyielding belief that  a
    mistake has been made"); see also Fed. R. Civ. P. 52(a).
    There  are,  however,  difficulties in  classification.
    Many cases involve what courts term "mixed" questions   questions
    which, if they are to be properly resolved, necessitate combining
    13
    factfinding  with  an elucidation  of  the applicable  law.   The
    standard of review applicable  to mixed questions usually depends
    upon  where  they fall  along the  degree-of-deference continuum:
    the  more fact-dominated the question, the more likely it is that
    the trier's resolution of it will  be accepted unless shown to be
    clearly erroneous.  See, e.g., United States v. Mariano, 
    983 F.2d 1150
    , 1158-59 (1st Cir.  1993); Roland M. v. Concord  Sch. Comm.,
    
    910 F.2d 983
    , 990-91 (1st Cir.  1990), cert. denied, 
    111 S. Ct. 1122
     (1991).
    Given that  the Supplementary  Treaty is silent  on the
    subject, we presume that the framers, in providing for appeals to
    the  federal courts,  intended  ordinary standards  of review  to
    apply.   See S.  Exec.  Rep. No.  17, supra,  at  8 ("Nothing  in
    article 3(b) is to be interpreted as .  . . upsetting established
    rules  of  appellate procedure.");  see  also  Gioiosa v.  United
    States, 
    684 F.2d 176
    , 179 (1st Cir. 1982) (discussing standard of
    review in  appeal from  magistrate to district  court).   Because
    issues of the sort envisioned in article 3(a) are typically fact-
    specific, appellate  review of  findings anent such  issues will,
    absent  an error of law, most often proceed under the clear-error
    rubric.  See, e.g., Pullman-Standard v. Swint, 
    456 U.S. 273
    , 289-
    90  (1982)   (reviewing  district   court  findings   anent  race
    discrimination  for clear  error); Beasley  v. Health  Care Serv.
    Corp., 
    940 F.2d 1085
    , 1088 (7th Cir. 1991) (similar in respect to
    discrimination based on  religious beliefs);  Rendon v. A  T &  T
    Technologies, Inc., 
    883 F.2d 388
    , 392 (5th Cir.  1989) (similar;
    14
    discrimination  based  on national  origin);  Gierbolini-Colon v.
    Aponte-Roque,  
    848 F.2d 331
    ,  333  (1st  Cir.  1988)  (similar;
    political discrimination); but cf.  Bose Corp. v. Consumers Union
    of  United States, Inc., 
    466 U.S. 485
    , 514  (1984) (holding that
    clearly  erroneous standard does  not apply  to review  of quasi-
    legal "finding" of actual malice in First Amendment context).
    This conclusion is buttressed by analogy to traditional
    habeas  corpus practice in the  extradition field.   When a party
    collaterally   challenges   a   magistrate's   determination   of
    extraditability, judicial review is sharply  circumscribed.  See,
    e.g.,  Fernandez v.  Phillips, 
    268 U.S. 311
    ,  312 (1925);  In re
    Manzi,  
    888 F.2d 204
    , 205  (1st Cir.  1989) (per  curiam), cert.
    denied,  
    494 U.S. 1017
     (1990).   The most  prominent exception is
    for  a  claim  that  the  crime  constitutes  a  non-extraditable
    political offense.   Review  of political  offense determinations
    follows the continuum analysis  described above.  See  Quinn, 783
    F.2d at  790-91 & n.9.   Because defenses under  article 3(a) are
    analogous  to  political  offense  determinations    indeed,  the
    fundamental  compromise  undergirding  the  Supplementary  Treaty
    treated the one  as a replacement  for the other    common  sense
    suggests that the same standard of review should apply.
    Last, but surely not least, appellant's contention that
    district court review under  article 3(b) must always be  de novo
    is  at war  with  the words  and  purposes of  the  Supplementary
    Treaty.  The  treaty expresses  a strong  interest in  expediting
    extradition  matters.    See  Supplementary  Treaty,  art.   3(b)
    15
    (providing  for  "immediate[]" appeals  and  requiring "expedited
    consideration at  every stage").   The legislative history  is in
    the  same  vein.    See,  e.g.,  132  Cong.  Rec.  16,607  (1986)
    (admonishing  that  the  treaty's  safeguards  should not  afford
    "protracted sanctuary in the United States").   Wholesale de novo
    review not  only would  ignore the factfinder's  superior vantage
    point  for judging the intricacies  of a contested  case but also
    would  be   wasteful,  engendering  unwarranted  delays   in  the
    extradition process.
    In  general,  then, reviewing  courts should  apply the
    clearly erroneous  standard to  the trier's  findings of  fact in
    situations  where article  3  of the  Supplementary Treaty  is in
    play.
    B.  Applying the Principles.
    In   this  case,   the  district   court  treated   the
    magistrate's  finding that  no  cognizable  article 3(a)  defense
    existed  as factual in  nature and applied  the clearly erroneous
    test.  As to  appellant's principal claim   that,  if extradited,
    he would suffer prejudice on account of his race or nationality
    we endorse the district  court's choice of a standard  of review.
    The  claim  in  question challenged  the  magistrate's underlying
    factual determination  that, on  the evidence  adduced, appellant
    had not proved meaningful prejudice.  This fact-intensive finding
    evokes clear-error review.4
    4Since  this  is  a   successive  appeal,  we  evaluate  for
    ourselves  whether  clear  error  characterized  the magistrate's
    factual  finding that appellant failed  to prove the existence of
    16
    There is, however, a second facet of appellant's claim,
    as  to which  the  district court  chose  the wrong  standard  of
    review.    The  magistrate  held  that  article  3(a)   does  not
    necessarily  bar  extradition  whenever  a  respondent shows  the
    existence  of some preformed  ideas in the  requesting nation but
    that  the biases  must  rise  to  a  level  where  they  actually
    prejudice  the respondent  before article  3(a)  affords relief.5
    The soundness of this  analysis   which depends upon  whether the
    terms employed  in article  3(a) encompass  all nationality-based
    and  race-based  biases  or   only  those  directly  affecting  a
    particular   respondent       involves   interpretation   of  the
    Supplementary Treaty.   Treaty  interpretation is a  purely legal
    exercise  as to which, under the criteria limned above, see supra
    Part IV(A), no deference is  due to the trier.  Accordingly,  the
    district court should have scrutinized the magistrate's ruling on
    this issue de novo.
    That the district court failed to afford plenary review
    on this aspect of the case does not mean that we must remand.  To
    do so  would needlessly throw the  helve after the hatchet.   See
    Gioiosa,  
    684 F.2d at 179
    .   Rather,  because the  question  is
    cognizable prejudice under article 3(a).  See infra Part VI.
    5In  a second branch  of his analysis,  the magistrate found
    that, in any event, the weight of the evidence against Howard was
    so great that  no decisionmaker  would be distracted  from it  by
    whatever slight biases might exist.  We express no opinion on the
    appropriateness of this analytic  approach as appellant "does not
    suggest  that the [magistrate] was expected  to ignore the weight
    of  the  probable cause  evidence"  in  making  his article  3(a)
    determination.  Appellant's Brief at 25.
    17
    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.  See, e.g., Societe  Des Produits
    Nestle,  S.A. v. Casa Helvetia, Inc., 
    982 F.2d 633
    , 642 (1st Cir.
    1992); Gioiosa, 
    684 F.2d at 179
    .
    V.  PREJUDICE UNDER THE SUPPLEMENTARY TREATY
    With this  preface, we proceed directly  to the treaty-
    interpretation question, affording plenary review.
    A.  Traditional Practice.
    A  sovereign's right  to obtain  the extradition  of an
    accused  is  created  by treaty;  where  there  is  no treaty,  a
    requested nation has no duty to extradite.  See Factor, 
    290 U.S. at 287
    .   Indeed, federal  courts have stated  that no branch  of
    government  has authority to  surrender an  accused to  a foreign
    country except in pursuance  of a statute or treaty.   See Quinn,
    783 F.2d at 782 (collecting cases).
    An extradition  treaty does more than  bridge this gap.
    The  existence of  such a  treaty between  the United  States and
    another nation indicates that,  at least in a general  sense, the
    executive  and legislative branches consider the treaty partner's
    justice  system sufficiently  fair  to  justify  sending  accused
    persons there for trial.  See Glucksman  v. Henkel, 
    221 U.S. 508
    ,
    512 (1911); Neely v.  Henkel (No. 1),  
    180 U.S. 109
    , 123  (1901).
    In  habeas corpus  proceedings, this  rationale has  produced the
    rule  of   noninquiry      a  doctrine  which   forbids  judicial
    authorities  from  investigating  the  fairness  of  a requesting
    18
    nation's  justice  system  when  considering  whether  to  permit
    extradition  to that  nation.   See Glucksman,  
    221 U.S. at 512
    ;
    Manzi, 
    888 F.2d at 206
     (collecting cases).6
    Of course, the signing of a treaty does not forever put
    to rest  questions concerning  the fairness of  another country's
    legal framework.   For example, an extradition target may present
    such  issues to  the  Secretary  of  State     the  official  who
    ultimately  decides whether  a  person found  to be  extraditable
    should  in fact  be extradited.    See 18  U.S.C.    3186.   But,
    traditionally, in extradition cases, the  judiciary neither asks,
    nor  seeks  to  answer,  questions about  the  sensitivities  and
    sophistication of courts abroad.7
    B.  Scope of Article 3(a).
    The Supplementary Treaty openly alters this traditional
    practice.   It requires judges to shun extradition if the accused
    6The government suggests that the  Constitution mandates the
    rule of noninquiry.  We disagree.  The rule did not spring from a
    belief that courts, as an  institution, lack either the authority
    or the capacity to  evaluate foreign legal systems.   Rather, the
    rule  came   into  being  as  judges,   attempting  to  interpret
    particular treaties, concluded that, absent a contrary indication
    in a specific instance, the ratification of an extradition treaty
    mandated  noninquiry  as a  matter of  international comity.   No
    doubt  the  rule  exemplifies  judicial  deference  to  executive
    authority, see Koskotas,  
    931 F.2d at 174
    , but it  is a deference
    stemming at least in part from the fact that the executive is the
    branch which most likely has  written and negotiated the document
    being interpreted.
    7The judiciary  has, however,  explicated a number  of other
    limitations  on extradition.  See,  e.g., Manzi, 
    888 F.2d at 207
    (explaining  that  the  principle  of  double   criminality  bars
    extradition unless  the offense is  a crime  in both  countries);
    Quinn,  783 F.2d at 792-810 (discussing origin of, and basis for,
    political offense exception in extradition proceedings).
    19
    either establishes that the request "has in fact been made with a
    view  to try  or punish  him on  account of  his  race, religion,
    nationality  or political  opinions,"  or if  he proves  that "he
    would, if surrendered,  be prejudiced at  his trial or  punished,
    detained or  restricted"  on account  of  any of  these  factors.
    Supplementary Treaty, art. 3(a).  These phrases cannot be brushed
    aside as  a series of scrivener's errors:  to the exact contrary,
    Congress  intended  the  words  to  authorize  inquiry  into  the
    attributes of  a country's  justice system  as that  system would
    apply to a given individual.  See S. Exec. Rep. No. 17, supra, at
    4-5;  132  Cong.  Rec.  16,798-803 (1986).    Moreover,  Congress
    evidently  knew that  its command  reversed years  of extradition
    practice forbidding judicial investigation  into such areas.  See
    132  Cong. Rec. 16,800 (1986) (describing article 3(a) as "a very
    broad,  and far  reaching provision");  id. at  16,806 (labelling
    this aspect of the treaty "historic").
    Still, the article  3(a) defense,  though a  refreshing
    zephyr  to persons  resisting  extradition, is  not of  hurricane
    force;  its mere invocation will  not sweep aside  all notions of
    international comity  and deference  to  the requesting  nation's
    sovereignty.    At least  four principles  rein  in the  winds of
    change.  First, elementary rules of construction dictate that the
    defense  not  be  construed  so  expansively  as  to  negate  the
    remainder of the treaty.   See, e.g., Factor, 
    290 U.S. at 292-93
    .
    The  rule  of noninquiry  developed from  the assumption  that an
    extradition treaty, by its  very existence, constitutes a general
    20
    acceptance  of another  country's legal system.   See  supra Part
    V(A).  By like  token, the existence of  an overall agreement  on
    extradition must inform the workings of the article 3(a) defense,
    limiting  its applicability to  specific problems  encountered by
    specific respondents, as opposed to general grievances concerning
    systemic  weaknesses  inherent in  every  case.   Otherwise,  the
    extradition treaty actually becomes an impediment to extradition,
    in other words,  a non-extradition  treaty.  See  132 Cong.  Rec.
    16,607 (1986).
    Second,  controlling  precedent  requires  that,  where
    possible,   we   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.
    Factor,  
    290 U.S. at 293-94
    .  These principles of reciprocity and
    liberal  construction  have  particular force  here  because  the
    United  States, unlike the U.K. and certain other nations, has no
    available  machinery  for  prosecuting  those  who commit  crimes
    abroad but who are, nonetheless, non-extraditable.  See 132 Cong.
    Rec. 16,587 (1986).
    Third, article  3(a) requires  an accused to  establish
    that  he would,  if  surrendered, be  "prejudiced" on  account of
    particular factors.   In our  view, this word  denotes that  only
    21
    those preformed ideas relative to race, nationality, and the like
    which  are  of  sufficient   magnitude  actually  to  affect  the
    accused's  situation,  i.e.,  to  "prejudice"  him,  trigger  the
    special prophylactic protections of the Supplementary Treaty.
    Finally,  the  legislative  history  suggests  that, in
    insisting upon  the inclusion  of article  3(a),  the Senate  was
    concerned  largely   with  the   special  Diplock  court   system
    applicable  to  those  accused  of  terrorist  acts  in  Northern
    Ireland.   See 132  Cong.  Rec. 16,806-19  (1986).   There is  no
    indication that the defense was meant  as a slur upon, much  less
    an indictment of, the British legal system.
    For these  four reasons, we  conclude that the  soil of
    this  case   is   particularly   inhospitable   to   a   rambling
    interpretation  of article 3(a).   We  hold, therefore,  that, in
    order  to  avail  himself   of  the  article  3(a)  defense,   an
    extradition  target  must establish  by  a  preponderance of  the
    credible  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.   It is not enough  simply to
    show some  possibility that preformed ideas  might exist; rather,
    under the terms of  the Supplementary Treaty, the bias  must rise
    to the level of  prejudicing the accused.  See  generally William
    M.  Hannay,  Committee  Report:   An  Analysis  of  the U.S.-U.K.
    Supplementary Extradition Treaty, 
    21 Int'l Law. 925
     (1987).
    C.  Appellant's "Per Se Prejudice" Argument.
    22
    We now face the task of applying the prejudice standard
    in  this case.    The record  reveals  that the  magistrate  paid
    careful  attention to an array of facts that sometimes pointed in
    different directions.   For  instance, he  found that there  were
    some negative articles about Howard,  that some Britons might  be
    biased  against  black  Americans, and  that  the  U.K.  does not
    utilize   a  voir   dire  procedure   to   screen  venirepersons.
    Nonetheless,  in  the  magistrate's  eyes, these  facts  did  not
    establish   an  article   3(a)  defense   because  countervailing
    considerations  mitigated  their negative  impact,  rendering any
    bias de minimis.   Appellant excoriates this finding, complaining
    that  it rests  upon a  faulty  legal premise.   He  asserts that
    article  3 effectively eclipses the  rule of noninquiry; that the
    evidence he tendered constitutes per se proof  of prejudice which
    irrebuttably establishes  an article  3(a) defense; and  that the
    Supplementary   Treaty  does  not  countenance  consideration  of
    countervailing factors  in mulling  whether a defense  is extant.
    We  concur  with the  magistrate  that  the Supplementary  Treaty
    stakes out a middle ground between the classic rule of noninquiry
    and  the total  abolition of that  rule:   the treaty  alters the
    traditional   formulation  of   the  rule   while  simultaneously
    preserving many aspects  of it.   Any other interpretation  would
    run afoul of the four constraining principles we have identified.
    See supra at 20-21.
    One  manifestation  of  this  middle  position is  that
    article  3(a),  as we  read it,  imposes  a de  minimis threshold
    23
    requirement relative to the existence of prejudice.  For example,
    because  international  criminal  affairs  are   frequently  high
    profile, a  per se rule  barring extradition  whenever there  has
    been any negative  publicity would undermine the entire treaty by
    making successful  article 3(a) defenses  virtually automatic and
    relegating  extradition to  a few  fringe instances.   We  do not
    think that the treaty partners intended so unproductive a result.
    Similar reasoning rules out any per se prohibition on extradition
    when  the accused  proffers evidence  suggesting discordant  race
    relations in the U.K. or when he simply points to  the absence of
    a specific procedural device.
    Consequently,   we  hold   that,  while   a  magistrate
    considering the applicability  of article 3(a) must weigh each of
    the  factors cited by  appellant if an  extradition target offers
    proof that  they exist, their  mere presence, without  more, does
    not  conclusively  establish  an  article  3(a)  defense.8    The
    something "more,"  as  we have  indicated,  is prejudice  to  the
    8This interpretation finds  analogies in prevailing  federal
    court  practice.  For instance,  we have routinely  held that the
    mere  presence   of   differing  procedural   devices,   pretrial
    publicity, or allegations  of community prejudice, without  more,
    does  not warrant overturning a criminal  conviction.  See, e.g.,
    Neron v.  Tierney, 
    841 F.2d 1197
    , 1199  (1st Cir.)  (admonishing
    against  the   use  of  habeas  corpus   to  superimpose  federal
    procedural choices  upon state courts merely  because the federal
    court  thinks some  "other" procedure  might be  "better"), cert.
    denied, 
    488 U.S. 832
     (1988); United  States v. Reveron-Martinez,
    
    836 F.2d 684
    ,  687  (1st  Cir.  1988)  (ruling  that  pretrial
    publicity, even though pervasive and  negative, did not warrant a
    presumption of prejudice); United States v. Gullion, 
    575 F.2d 26
    ,
    28  (1st  Cir.  1978)  (explaining  that  the  mere existence  of
    community  prejudice,  in and  of  itself,  does not  necessitate
    relief).
    24
    extradition  target.   It follows  that the  magistrate correctly
    construed  article   3(a)  to   require  a  showing   of  actual,
    respondent-specific prejudice.9  Appellant's per  se challenge to
    the magistrate's reasoning must, therefore, fail.
    VI.  THE MERITS OF THE ARTICLE 3(a) DEFENSE
    This  brings us  to the  merits of  Howard's fact-based
    challenge to  the decision below     an issue that  gives us some
    pause.10   Nevertheless,  in seeking  to  secure an  article 3(a)
    defense, an extradition  target bears  a heavy burden.   He  must
    establish,  by a preponderance of the evidence, that he would, if
    surrendered,  be prejudiced  on account  of a  proscribed factor.
    See  Supplementary Treaty,  art.  3(a); see  also 132  Cong. Rec.
    16,607  (1986).  Having painstakingly  reviewed the papers in the
    case in  light of the burden  of proof, we cannot  say that clear
    error inheres.
    Appellant   introduced  numerous   newspaper  articles,
    affidavits from several  people living in Great Britain,  and the
    testimony  of  Paul  Stevenson,  a senior  executive  officer  of
    England's  Commission  for  Racial  Equality, in  an  attempt  to
    9We  note, in  passing,  that the  rules governing  criminal
    trials  in the federal courts  seem fully compatible  with such a
    requirement.   See,  e.g., Fed.  R. Crim.  P. 52(a)  ("Any error,
    defect,   irregularity  or   variance   which  does   not  affect
    substantial rights shall be disregarded.").
    10We refer only to appellant's claim that, if extradited, he
    would be prejudiced on account of his race.  He presented little,
    if  any, evidence suggesting  the existence  of nationality-based
    biases in this  case, and we  cannot discern any error  (clear or
    otherwise) in  the magistrate's finding that  appellant failed to
    prove cognizable prejudice of this genre.
    25
    establish  that  widespread  publicity  would  prevent  him  from
    receiving fair treatment abroad.   But, this evidence comprises a
    mixed bag.  It is true that some of the press clippings contained
    racial innuendo.  On the other hand, the publicity was mercifully
    brief in  duration, for the most  part lasting less than  a week;
    the U.K.'s  Contempt of Court  Act has been invoked  and will cut
    off  any  further  untoward publicity;  Howard's  counsel himself
    created  some  of the  notoriety in  his  rousing remarks  to the
    British  press;   the  media   coverage  was  not   uniformly  or
    overwhelmingly negative (indeed,  some of the newspaper  articles
    describe  appellant  favorably);  and,  finally,   the  publicity
    occurred over two years ago and will be very old news when and if
    appellant  eventually  comes  to  trial  in  England.    On  this
    conflicted record, the magistrate  did not perpetrate clear error
    in finding  that a spurt  of mixed publicity  created in part  by
    appellant's counsel and occurring years ago failed to rise to the
    level of prejudice necessary to sustain an article 3(a) defense.
    The evidence  in  the record  concerning  the  supposed
    shortcomings  of the  requesting nation's  legal system  does not
    require  a different result for  it, too, is  mixed.  Admittedly,
    appellant  presented  affidavits  and testimony  suggesting  that
    preformed   ideas  constitute   a   particular   threat  in   the
    circumstances  of this case  because the English  system does not
    provide for American-style voir  dire of potential jurors.   But,
    evidence  submitted   by   the  government   and  elicited   from
    appellant's  witness  on  cross-examination  indicates  that  the
    26
    English legal system has a host of other mechanisms which will be
    available to  appellant and  which mitigate  the absence  of voir
    dire.  Appellant will be able to present his arguments concerning
    the  impact  of  pretrial  publicity and  race  relations  during
    committal  proceedings in  the  U.K.    He  may  then  renew  the
    arguments by requesting pretrial review at the Crown Court, again
    before  the trial  judge,  and still  again  on appeal  from  any
    conviction.  In  addition, the English system provides  for self-
    excusal of  potentially biased jurors  and trial judges  are duty
    bound  to  offer   detailed  jury  instructions  concerning   the
    impropriety  of grounding  defendants' convictions  on extraneous
    considerations.  Seen in this light, the absence of voir dire  in
    the  English system is not of decretory significance.  After all,
    courts must not let jingoism  run amok, but, rather, must turn  a
    sympathetic ear to other nations' independent judgments about how
    best  to ensure fairness in  dealing with criminal  matters.  The
    United States has no monopoly on even-handed justice.
    To  summarize,  the   evidence  concerning   prejudice,
    properly decanted, is ambivalent.  The facts we have  catalogued,
    and  others in  the  record, comprise  adequate  support for  the
    magistrate's  conclusion that  any evidence  of bias  relating to
    appellant's race is so  exiguous as not to animate  article 3(a).
    Put  another way, the magistrate weighed the proof, drew a series
    of  reasonable (albeit  not inevitable)  inferences from  it, and
    concluded that appellant  had not carried  the burden of  proving
    prejudice.   We cannot say that this choice between two plausible
    27
    alternatives,  each  of  which   finds  support  in  the  record,
    constitutes  clear error.  See Anderson v. City of Bessemer City,
    
    470 U.S. 564
    , 573-74  (1985); United States v. Rodriguez-Morales,
    
    929 F.2d 780
    , 784 (1st Cir. 1991),  cert. denied, 
    112 S. Ct. 868
    (1992).
    VII.  CONCLUSION
    We  need  go   no  further.11     Article   3  of   the
    Supplementary   Treaty  significantly   alters  the   pattern  of
    procedural avenues and substantive rights traditionally available
    in extradition  cases.   While these alterations  reconfigure the
    extradition   landscape,  they  do   not  render  it  impassable.
    Following  the map that Article  3 supplies, we  conclude that we
    have  jurisdiction  to  consider  appellant's  claims;  that  the
    standard of review governing his legal challenge is de novo; that
    the standard  of review governing his fact-based challenge is for
    clear error; that  appellant's arguments anent  the scope of  the
    article 3(a) defense  envision a grandeur which lacks  support in
    the treaty's language or in the applicable law; and, that, in the
    last analysis,  the magistrate's  findings of fact  derive enough
    support from  the record to  withstand attack.   Accordingly, the
    11We do  not tarry  over the assertion  that the  magistrate
    erred  in denying appellant's motions  to stay proceedings and to
    supplement the  evidence.   These motions  were addressed  to the
    magistrate's discretion, and he  provided ample reasons for their
    denial.   In the same vein,  we see no error  in the magistrate's
    discretionary   decision   allowing   the  government   to   file
    confirmatory  materials  out  of  time.     On  this  score,  the
    sockdolager is that appellant neither sought to reopen the record
    to  counter  or  contest  the  belated  evidentiary  proffer  nor
    requested time for this specific purpose.  He cannot now be heard
    to complain that he had no chance to respond.

    district  court lawfully  upheld the  magistrate's issuance  of a
    certification of extraditability.
    Affirmed.
    Concurring Opinion Follows
    29
    CAMPBELL, Senior Circuit Judge (Concurring).  While
    joining  in  the  court's  opinion,  I  am  troubled  by  our
    resolution of  the "successive appeals" issue.   Article 3(b)
    provides that  a finding concerning an  Article 3(a) defense,
    involving race, religion, nationality, or  political opinion,
    "shall  be  immediately appealable  by  either  party to  the
    United  States  district  court,  or  court  of  appeals,  as
    appropriate."   We hold  that this unclear  language does not
    indicate that  an appellant receives only one appeal    i.e.,
    an appeal to the  district court, if the  initial extradition
    decision was  by a magistrate, or  an appeal to the  court of
    appeals if the initial extradition decision was by a district
    judge     but rather was meant to  provide, however clumsily,
    for  the full federal appellate process.  Thus, where as here
    the  initial  extradition  decision  was by  the  magistrate,
    appellant  can  appeal, (1)  to  the  United States  district
    court; (2) from  the  district court  to this  court; and,  I
    assume, (3) from  this court to the Supreme  Court by writ of
    certiorari.
    It  is sad but true that this interpretation of the
    ambiguous language     while  seemingly what was  intended
    creates significant new  opportunities for  persons to  delay
    their extradition.  Historically, extradition decisions  by a
    judge or  magistrate were  not appealable, thus  avoiding the
    potential  delays  which   often  attend  appellate   review.

    Obviously,  the  more  extradition  is susceptible  to  being
    bogged  down in endless  procedural maneuvering,  the greater
    the danger that essential witnesses  to the charged crime may
    die or disappear and their memories fade prior to trial.   It
    used to  be thought  that the  interest of  another civilized
    nation  in enforcing  its  criminal law  entitled  it to  the
    reasonably  prompt  extradition  of  accused  persons.    The
    present appeal to this court  has enabled appellant to  delay
    trial in Great Britain by another year or more.
    It would have been useful had  the United States of
    America gone more deeply,  in its briefs before us,  into the
    pros and cons  of the proper interpretation  of Article 3(b).
    In  a Treaty  case  of first  impression, the  interpretation
    espoused by  the Attorney  General can  be enlightening.   As
    best I can tell, the Attorney General agrees with the court's
    reading of the  Treaty, i.e., that the full federal appellate
    process, and not a truncated version, was intended.  However,
    the alternative interpretation    what my colleagues call the
    "one bite of the  apple" approach     has  some appeal  given
    Article  3(b)'s  literal  language  and  the  long  tradition
    divorcing extradition from the  normal appellate process.  We
    could have  benefited from  a more considered  explication of
    all this by the United States.
    In  any  event,  I  write separately  in  order  to
    emphasize  the  implications  of  Article  3(b),  as  we  now
    -30-
    30
    interpret it, so that the drafters  of future provisions will
    have no  illusions  concerning the  inevitable potential  for
    delay,  and  may decide  whether  other  approaches would  be
    desirable.
