  •                  IN THE UNITED STATES COURT OF APPEALS
    FOR THE FIFTH CIRCUIT
    No. 92-7493
    IN RE:   AMERICAN AIRLINES, INC.,
    AMR CORPORATION,
    Petitioners.
    Petition for Writ of Mandamus
    to the United States District Court
    for the Southern District of Texas
    ( September 4, 1992 )
    Before POLITZ, Chief Judge, HIGGINBOTHAM, and BARKSDALE, Circuit
    Judges.
    HIGGINBOTHAM, Circuit Judge:
    American Airlines, Inc. petitions for a writ of mandamus
    directing the district court to disqualify its former counsel
    Vinson & Elkins from representing plaintiff Northwest Airlines,
    Inc.    We hold that the district court erred in denying American's
    motion and issue the requested writ.
    I
    Continental Airlines filed a complaint against American in the
    United States District Court for the Southern District of Texas on
    June 8, 1992, charging American with attempted monopolization by
    predatory pricing in violation of the Sherman Act.       American filed
    a declaratory judgment action against Continental and Northwest in
    the United States District Court for the Northern District of
    Illinois the following day.           Three days later, Northwest sued
    American in the Southern District of Texas.             The Continental and
    Northwest suits have been consolidated by order of the district
    court.
    On   June   9,   1992,   the    day   after    Continental   filed   its
    complaint,   David    Schwarte,     American's     in-house   counsel,   asked
    Alison Smith, a VE partner, if VE would represent American in this
    case.     Smith accepted the American representation on June 10,
    unaware that four days earlier Harry Reasoner, another VE partner,
    had promised Joe Jamail, Northwest's counsel, that VE would not
    consider representing another airline until Jamail and Reasoner had
    discussed joining forces.         When Smith informed Reasoner of her
    acceptance of the American representation, Reasoner directed her to
    inform Schwarte that "there might be a problem with Northwest" and
    that Reasoner would make the final decision the next day.            On June
    11 Reasoner accepted the Northwest representation.
    American asserted that VE's prior representation of American
    and its agreement to do so in this case made its representation of
    Northwest improper. It requested that VE withdraw from the case in
    letters sent on June 12 and June 19.               Northwest refused and on
    July 1 American moved to disqualify VE.            The parties at this time
    became aware that Weil, Gotshal & Manges, American's lead counsel,
    had previously represented Northwest and Continental.             An exchange
    of "conflicts" was briefly considered.              When American indicated
    2
    that it would not withdraw its motion to disqualify VE, Northwest
    moved to disqualify Weil, Gotshal on July 13.
    American rests its motion to disqualify Vinson & Elkins on
    VE's representation of American in prior antitrust matters and its
    alleged agreement to represent it in this case.                 According to
    American, Vinson & Elkins has served as its "Houston" antitrust
    counsel since 1987.     In this role VE defended American in suits by
    Continental   and   a   Continental       affiliate.    VE   also   provided
    antitrust advice in connection with American's possible acquisition
    of Continental.
    On July 24, after extensive briefing and the submission of
    numerous affidavits, the district court denied both motions to
    disqualify counsel. The court held that VE's initial acceptance of
    the American representation was a "mixup," that the past matters in
    which VE had represented American were only "tangentially related
    to   this   litigation,"   and   that      any   confidential    information
    possessed by VE was "not sufficient to cause any material prejudice
    to [American]."     The court directed the parties to submit a plan
    for a Chinese Wall to safeguard against adverse use of confidential
    information in the case. American then filed the petition for writ
    of mandamus now before us.
    II
    We must first determine our jurisdiction.              Orders denying
    motions to disqualify counsel are not appealable before final
    judgment under 28 U.S.C. § 1291.           Firestone Tire & Rubber Co. v.
    Risjord, 
    449 U.S. 368
    , 375 (1981); see also Richardson-Merrell,
    3
    Inc. v. Koller, 
    472 U.S. 424
    (1985) (extending rule to orders
    granting     motions     to   disqualify).       While    holding      that
    disqualification orders are not immediately appealable as a matter
    of course, the Firestone Court indicated that a writ of mandamus
    might be available "in the exceptional circumstances for which it
    was designed."    
    Firestone, 449 U.S. at 378
    n.13; 
    Koller, 472 U.S. at 435
    .    American contends that this case presents the requisite
    "exceptional circumstances."
    The standards are well established:       "[P]etitioners must show
    that they lack adequate alternative means to obtain the relief they
    seek . . . and carry the 'burden of showing that [their] right to
    issuance of the writ is "clear and indisputable."'"            Mallard v.
    United States Dist. Ct. for the S. Dist. of Iowa, 
    109 S. Ct. 1814
    ,
    1822 (1989) (citations omitted); In re Fibreboard Corp., 
    893 F.2d 706
    , 707 (5th Cir. 1990); In re Willy, 
    831 F.2d 545
    , 549 (5th Cir.
    1987).     The test contains two prongs, one procedural and one
    substantive, and unless American demonstrates that it lacks an
    adequate alternative means to obtain relief, we need not consider
    whether    its   right   to   a   writ   of   mandamus   is   "clear    and
    indisputable."
    Courts confronting this question have suggested that "[d]enial
    of a motion to disqualify counsel will rarely justify the issuance
    of a writ of mandamus."       In Re Ford Motor Co., 
    751 F.2d 274
    , 275
    (8th Cir. 1984); see also In re Mechem, 
    880 F.2d 872
    , 873 (6th Cir.
    1989); In re Bushkin Assocs., Inc., 
    864 F.2d 241
    , 243-44 (1st Cir.
    1989).    We agree that frequent use of the writ would "'undermine[]
    4
    the policy against piecemeal appellate review,'" 
    Mechem, 880 F.2d at 875
    (quoting Allied Chemical Corp. v. Daiflon, Inc., 
    449 U.S. 33
    , 36 (1980) (per curiam)), and thus we have stressed that
    "mandamus may not serve as a substitute for appeal."     Warren v.
    Bergeron, 
    831 F.2d 101
    , 103 (5th Cir. 1987).         We also have
    recognized, however, that the standard governing the availability
    of mandamus is not "never," but "hardly ever."    Allied 
    Chemical, 101 S. Ct. at 190
    .   Thus, this court has recently held that a writ
    of mandamus will be available in certain cases to obtain immediate
    review of a district court's denial of a disqualification motion.
    In re Dresser Industries, No. 92-2199 (5th Cir. Aug. 21, 1992).
    See also In re American Cable Publications, Inc., 
    768 F.2d 1194
    (10th Cir. 1985) (issuing writ on petition to review a grant of
    disqualification motion); Merle Norman Cosmetics, Inc. v. United
    States Dist. Ct., Central Dist. of Cal., 
    856 F.2d 98
    , 101 (9th Cir.
    1988) (recognizing that "if petitioners' claims were wellfounded
    [sic], the damage would be irremediable," but denying writ on other
    grounds).   As in Dresser, we find the special circumstances of the
    present dispute sufficient to place it within that narrow class of
    cases warranting mandamus review.
    American claims that immediate review of its disqualification
    motion is appropriate because it will otherwise suffer "irreparable
    harm" and also because "attorneys and clients throughout Texas need
    the benefit of this Court's guidance on this issue of grave
    importance."    We agree.    First, the nature and size of this
    litigation would seem to preclude effective appellate review upon
    5
    final judgment.     In addition, this case raises several questions
    pertaining to the proper interpretation and application of ethical
    standards in disqualification cases.           As illustrated by our recent
    Dresser opinion,     it   is   relevant   to    mandamus    review      that   the
    "district court's order was not a mere discretionary one but rather
    turns on legal questions appropriate for appellate review."                In re
    Burlington N., Inc., 
    822 F.2d 518
    , 523 (5th Cir. 1987).                It is also
    relevant that, as in Dresser and Burlington, "[t]he issues here
    also have importance beyond the immediate lawsuit." 
    Id. at 523;
    In
    re EEOC, 
    709 F.2d 392
    , 394-95 (5th Cir. 1983).             For these reasons,
    we hold that American has demonstrated the absence of an adequate
    alternative to mandamus review.
    Having   met   the   "procedural"     requirement       for   a    writ   of
    mandamus, American must also demonstrate that its right to the
    issuance of the writ is "clear and indisputable."             This test goes
    to the merits, and we pause only to set out the standard of review.
    The Supreme Court has indicated that "[w]here a matter is committed
    to discretion, it cannot be said that a litigant's right to a
    particular result is 'clear and indisputable.'"             Allied 
    Chemical, 101 S. Ct. at 191
    .     In accord with these dictates, this court has
    held that a writ of mandamus should not issue merely because we
    believe that "we might have exercised the discretion vested in that
    court differently than the district court exercised it." Matter of
    Hester, 
    899 F.2d 361
    , 367 (5th Cir. 1990).
    In this circuit, however, a district court's ruling upon a
    disqualification motion is not a matter of discretion. Rather, the
    6
    appellate court "review[s] findings of fact for clear error 'while
    carefully examining the district court's application of relevant
    ethical standards.'"         Johnston v. Harris County Flood Control
    Dist., 
    869 F.2d 1565
    , 1569 (5th Cir. 1989) (quoting Cossette v.
    Country Style Donuts, Inc., 
    647 F.2d 526
    , 531 (5th Cir. 1981)).
    Conceding that abuse of discretion review is not appropriate,
    Northwest asserts that this case centers on disputed factual
    matters, and that the district court's findings deserve deference.
    Assuming arguendo that the district court made findings on these
    contested questions of fact, it is clear that the court was guided
    by a particular reading of the Texas Disciplinary Rules in making
    these relevant factual determinations.            Whatever deference due the
    court's factual findings, little or no deference is proper in
    reviewing its interpretation of ethical rules.             We have recently
    held   that    a   "district      court's     interpretation   of   the   state
    disciplinary       rules   [is]    an   interpretation    of   law,   subject
    essentially to de novo consideration."            Dresser, No. 92-2199, slip
    op. at 6975-76.      In accord with Dresser, our review of the district
    court's reading of the relevant ethical standards will be de novo.
    III
    We turn to the applicable law.              The Local Rules of the
    Southern District of Texas provide that "[t]he Code of Professional
    Responsibility adopted by this court is the Code of Professional
    Responsibility of the State Bar of Texas, as amended from time to
    time."    Tex. Rules of Court, Federal App. A, Rule 4B.                   Texas
    replaced the Texas Disciplinary Code with the Texas Disciplinary
    7
    Rules of Professional Conduct in 1990.        Recognizing the new Rules
    as an amendment of the old Code, this Court has applied the Rules.
    See In re Medrano, 
    956 F.2d 101
    , 102 n.3 (5th Cir. 1992).               The
    parties do not contest application of the Rules.
    We have recently held, however, that the Texas Rules, as
    adopted by the Southern District of Texas, are not the "'sole'
    authority governing a motion to disqualify." Dresser, No. 92-2199,
    slip op. at 6976.     In reviewing a motion to disqualify, "we
    consider the motion governed by the ethical rules announced by the
    national profession   in   light   of   the   public   interest   and   the
    litigants' rights." 
    Id. As Dresser
    indicates, our precedents have
    applied the ethical canons contained in the ABA Model Code.             See,
    e.g., Brennan's Inc. v. Brennan's Restaurants, Inc., 
    590 F.2d 168
    (5th Cir. 1979); Woods v. Covington County Bank, 
    537 F.2d 804
    (5th
    Cir. 1976).
    The parties' extensive citation of this court's precedents
    applying the ABA Model Code suggests their recognition that the
    Texas Rules, as adopted by the Southern District of Texas, are not
    the "sole" authority governing this case.          Moreover, we do not
    believe that our holding in Dresser has rendered the parties'
    arguments grounded in the Texas Rules irrelevant to our decision.
    The Texas Rules were patterned after the ABA Model Rules of
    Professional Conduct, which the Dresser court cited along with the
    Model Code as the national standards utilized by this circuit in
    ruling on disqualification motions.      Since the relevant ABA Rules
    do not differ materially from the corresponding Texas Rules, the
    8
    parties' interpretations of the Texas Rules are equally applicable
    in this case.       Our discussion will therefore center on the Texas
    Rules.
    As we confirmed in Dresser, "[m]otions to disqualify are
    substantive motions affecting the rights of the parties and are
    determined by applying standards developed under federal law."
    Dresser, No. 92-2199, slip op. at 6976; see also In re Snyder, 
    105 S. Ct. 2874
    , 2881 n.6 (1985); In re Finkelstein, 
    901 F.2d 1560
    , 1564
    (11th Cir. 1991); United States v. Miller, 
    624 F.2d 1198
    , 1200 (3d
    Cir. 1980); Cord v. Smith, 
    338 F.2d 516
    , 524 (9th Cir. 1964).
    Federal courts may adopt state or ABA rules as their ethical
    standards, but whether and how these rules are to be applied are
    questions    of    federal   law.     We   stress   this    because   Northwest
    contends that the Texas Rules control the discretion of a district
    court.     According to Northwest, "a trial court is not forced by
    literalism or mechanical standards to do injustice serving the mere
    litigation tactics of a party.        Rather, a trial court, according to
    the   Rules,   is   to   determine    if   there    is    actual   prejudice   or
    threatened interference with the fair administration of justice."
    See Texas Rule 1.06 Comment 17; ABA Rule 1.7 Comment.
    As we have indicated, disqualification cases are governed by
    state and national ethical standards adopted by the court.                     We
    disagree    with    Northwest's     suggestion     that   these    sources   also
    determine the discretion of a district court applying these rules.
    That issue is one governed by federal law.
    9
    Some courts have taken the position Northwest advances, namely
    that "[t]he business of the court is to dispose of litigation and
    not to act as a general overseer of the ethics of those who
    practice here unless the questioned behavior taints the trial of
    the cause before it."    W.T. Grant Co. v. Haines, 
    531 F.2d 671
    , 677
    (2d Cir. 1976); Board of Educ. v. Nyquist, 
    590 F.2d 1241
    , 1246 (2d
    Cir. 1979); Armstrong v. McAlpin, 
    625 F.2d 433
    , 445-46 (2d Cir
    1980). See also Sutton, How Vulnerable is the Code of Professional
    Responsibility?, 57 N.C.L.Rev 497, 514-16 (1979).          An attorney's
    ethical violation by itself does not warrant disqualification under
    this approach.     Rather, disqualification is proper only in cases
    where a court also finds that the unethical conduct threatens to
    taint the trial.    This more limited test largely rests on a belief
    that disqualification motions are often made for tactical reasons
    such as delay or harassment.      While the "taint" standard "fails to
    correct all possible ethical conflicts," 
    Armstrong, 625 F.2d at 445
    , it is argued that this limited disqualification rule serves to
    deter many meritless, tactical motions that would otherwise be
    filed.
    This   circuit,   however,    has   struck   a   different   balance,
    electing to remain "sensitive to preventing conflicts of interest."
    Matter of Consolidated Bankshares, Inc., 
    785 F.2d 1249
    , 1256 (5th
    Cir. 1986).   We have squarely rejected this hands-off approach in
    which ethical rules "guide" whether counsel's presence will "taint"
    a proceeding, holding instead that a "[d]istrict [c]ourt is obliged
    to take measures against unethical conduct occurring in connection
    10
    with any proceeding before it."              Woods v. Covington County Bank,
    
    537 F.2d 804
    , 810 (5th Cir. 1976) (emphasis added); Musicus v.
    Westinghouse Elec. Corp., 
    621 F.2d 742
    , 744 (5th Cir. 1980); E.F.
    Hutton & Co. v. Brown, 
    305 F. Supp. 371
    , 376-77 (S.D. Tex. 1969);
    see also Kevlik v. Goldstein, 
    724 F.2d 844
    , 847 (1st Cir. 1984)
    ("the district court has the duty and responsibility of supervising
    the conduct of attorneys who appear before it"); Trust Corp. v.
    Piper Aircraft Corp., 
    701 F.2d 85
    , 87 (9th Cir. 1983) (same);
    United States v. Agosto, 
    675 F.2d 965
    , 969 (8th Cir. 1982) (same).
    For this reason, we have emphasized that "[a] motion to disqualify
    counsel is the proper method for a party-litigant to bring the
    issues of conflict of interest or breach of ethical duties to the
    attention of the court."       
    Musicus, 621 F.2d at 744
    .              We recognize
    of course that disqualification motions may be used as "procedural
    weapons" to advance purely tactical purposes.                     But we do not
    believe   that   a   priori   assumptions       concerning      the   motivations
    underlying disqualification motions in general justify a more
    relaxed ethical rule.     Our prior cases disclose that a careful and
    exacting application of the rules in each case will separate proper
    and improper disqualification motions.
    Our rejection of the "taint" standard finds additional support
    in the questionable nature of the assumptions underlying the test.
    First, the    "taint"    standard       rests   on   a   belief   that    "ethical
    conflicts    surfacing   during     a    litigation      are   generally   better
    addressed by the 'comprehensive disciplinary machinery' of the
    state and federal bar."           
    Armstrong, 625 F.2d at 446
    (quoting
    11
    
    Nyquist, 590 F.2d at 1246
    )).   It is not not clear that the vitality
    of state enforcement is relevant to the judicial duty of the
    federal courts to clean its own house.    Policy aside, it is equally
    uncertain that the disciplinary boards have performed this role.
    Moreover, clients and fellow attorneys have little incentive to
    file formal complaints with disciplinary boards, and the evidence
    suggests that they in fact do not.        This is especially true in
    cases of alleged conflicts of interest.        See David B. Wilkins, Who
    Should Regulate Lawyers?, 105 Harv. L. Rev. 799, 827-28 (1992);
    Note, Developments in the Law--Conflicts of Interest in the Legal
    Profession, 94 Harv. L. Rev. 1244, 1496-1500 (1981).          To a very
    large extent, unless a conflict is addressed by courts upon a
    motion for disqualification, it may not be addressed at all.         More
    to the point, it is our business--our responsibility.
    Second, we believe that today there is less reason to suspect
    tactical motivations behind disqualification motions than at the
    time the "taint" standard was initially formulated in the 1970's.
    This is not due to any moral transformation of the bar, but to the
    relative absence of tactical advantages that might be secured by
    disqualification   orders   under    today's    law.    At   that   time,
    disqualification orders were immediately appealable; the greatest
    tactical advantage offered by these motions was delay, as the trial
    proceedings were halted while the motion went up on appeal.          See,
    e.g., 
    Nyquist, 590 F.2d at 1246
    .         Under the Firestone regime,
    however, disqualification motions are not appealable prior to final
    judgment, thus severely limiting any advantages a party might have
    12
    achieved through delay.         See 
    Armstrong, 625 F.2d at 452
    n.2
    (Newman, J., concurring in part and dissenting in part).
    Accordingly, we will rigorously apply the relevant ethical
    standards in reviewing American's disqualification motion, just as
    we have done in the past.         See, e.g., Johnston v. Harris County
    Flood Control Dist., 
    869 F.2d 1565
    , 1569 (5th Cir. 1989); Doe v. A
    Corp., 
    709 F.2d 1043
    , 1046 (5th Cir. 1983); In re Corrugated
    Container Antitrust Litigation, 
    659 F.2d 1341
    (5th Cir. Unit A Oct.
    1981); Duncan v. Merrill Lynch Pierce, Fenner & Smith, Inc., 
    646 F.2d 1020
    (5th Cir. Unit B June 1981).               We will now examine the
    three arguments offered by American in support of its motion to
    disqualify Vinson & Elkins from representing Northwest.

    American first argues that VE must be disqualified from
    representing Northwest because a law firm may not switch sides in
    the same case.      According to American, a binding attorney-client
    relationship between VE and American was formed when Alison Smith,
    a VE partner, agreed to represent American on June 10.                        VE's
    withdrawal from the American representation and acceptance of the
    Northwest representation on June 11 was a switch of sides in the
    same case, a clear violation of legal ethics.
    Texas   Rule    1.06(a)   provides       that   "[a]   lawyer    shall   not
    represent    opposing   parties    to     a    litigation."      As    American
    indicates, this rule applies even in cases where an attorney-client
    relationship has not been formed: A lawyer may not "switch[] sides
    and represent[] a party whose interests are adverse to a person who
    13
    sought in good faith to retain the lawyer."              Texas Rule 1.09
    Comment 4A; see also Hazard & Hodes, The Law of Lawyering § 1.9:111
    (1991). The parties agree that Alison Smith agreed to represent
    American on behalf of VE on June 10, and that Harry Reasoner
    formally agreed to represent Northwest on June 11.                  There are
    significant differences, however, on several points that bear on
    the dispositive question of whether American sought to retain VE in
    good faith.
    On June 5, 1992, Northwest, through Joe Jamail, spoke to Harry
    Reasoner, managing partner of VE, about the possibility of VE
    serving as Northwest's co-counsel in a suit against American.
    After checking to see whether American was a current client and
    reviewing the matters that VE had handled for American in the past,
    Reasoner     promised    Jamail   that     VE   would   accept      no   other
    representation of an airline until he had the chance to discuss the
    matter further.
    On June 9, David Schwarte of American, after first attempting
    to   reach   Reasoner,   called   Alison    Smith,   another   VE    partner.
    Schwarte asked Smith if VE would represent American in a suit that
    Continental had filed against it in Galveston.             Unaware of the
    previous discussion between Jamail and Reasoner, Smith stated that
    she would be "delighted" to take on the case, but added that she
    would first have to run a conflicts check.        American sent VE copies
    of the complaints filed against it later that day.
    Smith called Schwarte at around 9:00 a.m. the next morning,
    June 10.     When Smith stated that the conflicts question had not yet
    14
    been   resolved,   Schwarte   asked    if   there   was   a   problem   with
    Northwest.     Smith responded that no such conflict was apparent.
    Smith and Schwarte then discussed American's possible litigation
    strategy, focusing on American's desire to transfer the Galveston
    case to Chicago.
    A disputed conversation between David Boies of Cravath, Swaine
    & Moore, lead counsel for Continental, and Ira Millstein of Weil,
    Gotshal & Manges, lead counsel for American, occurred at about 9:30
    a.m.   According to Boies, Millstein stated that he hoped to retain
    VE to represent American in the Galveston case.           Boies responded
    that this probably was not possible, for it was his understanding
    that VE would be representing Northwest in a suit against American.
    Millstein, however, asserts that he told Boies that VE would be
    representing American in Galveston, and that Boies responded that
    VE might have a conflict with Northwest, not that VE was going to
    sue American on Northwest's behalf.
    At 10:30 a.m., Smith informed Schwarte that there were no
    conflicts that might prevent VE from representing American.             Upon
    hearing this, Schwarte asked Smith if there was any reason why "we"
    could not begin to act as a team.      Smith responded that she did not
    see why not.    The two again spoke of American's desire to transfer
    the Galveston case to Chicago.         Schwarte asked Smith to begin
    thinking about this question and told her that he would send her a
    memorandum on the subject prepared by Weil, Gotshal attorneys.
    After the call, Smith left Reasoner a note in his office, stating
    15
    that she had accepted the American representation in the Galveston
    case.
    Reasoner       learned    of    Smith's    acceptance    of    the   American
    representation when he called his office at around 12:30 p.m.                    He
    advised Smith to explain to Schwarte that until Smith and Reasoner
    were able to discuss the matter, it was uncertain whether VE would
    be able to accept.            Smith called Schwarte at 2:20 p.m.                The
    contents of this conversation are in dispute.               According to Smith,
    she told Schwarte that Reasoner had informed her that there was a
    problem with VE representing American.              Schwarte responded that he
    was not surprised, for he had learned from Millstein that Reasoner
    had spoken     to    Northwest      about   suing   American.       According    to
    Schwarte, however, Smith stated only that she had received a
    "cryptic note" from Reasoner indicating that "there might be a
    problem with Northwest."            Schwarte swears that he made no mention
    of the possibility that VE might represent Northwest.                      At 3:45
    p.m., VE received a copy of the memorandum prepared by Weil,
    Gotshal that Smith and Schwarte had discussed earlier.
    Schwarte and Smith spoke again at 5:30 p.m.                   Smith informed
    Schwarte that       the   "problem     with    Northwest"    had   not    yet   been
    resolved.    Schwarte stated that he needed to know as soon as
    possible in order to make other arrangements if it turned out that
    VE could not represent American. At 5:45 p.m., Reasoner told Smith
    that he planned to read the complaints in the case and would speak
    to American the next day.             Smith called Schwarte to convey this
    information.
    16
    Northwest alleges that Irv Terrell, a partner at Baker &
    Botts, informed Joe Jamail this same afternoon that Baker & Botts
    would   be    representing     American.          Both    Terrell     and   Schwarte,
    however, sharply contradict this account, asserting that American
    did not retain Baker & Botts until the afternoon of June 11, after
    VE told American that it would be representing Northwest.
    The next afternoon, June 11, Reasoner and Jamail agreed that
    VE would serve as co-counsel for Northwest.                 Reasoner then called
    various members of American's legal team with this news. Millstein
    at this time asked Reasoner if he could recommend other Houston
    counsel.      Reasoner told him that Baker & Botts would be a good
    choice.      On Reasoner's instructions, Smith returned unread the
    Weil,   Gotshal      memorandum    she      had    received     the    day     before.
    According to American, American retained Baker & Botts later that
    afternoon.
    The parties' respective accounts of these events diverge at
    several      significant    points.      The      rule     barring    lawyers    from
    switching sides in the same case applies only where the complaining
    party sought in good faith to retain the lawyer.                    Texas Rule 1.09
    Comment 4A.      Northwest's version of events might lead a court to
    question American's good faith. According to Northwest, American's
    lead counsel was informed that VE would be representing Northwest
    in   a suit     against    American    before      Alison    Smith,     who,   unlike
    American,      had   no    knowledge   of     VE's       previous    commitment    to
    Northwest, agreed to represent American.                 Northwest also contends
    that American hired Baker & Botts during the afternoon of June 10,
    17
    before VE's final decision that it would not represent American.
    Northwest alleges that American sent VE the confidential memorandum
    prepared by Weil, Gotshal after these two events, that is, with
    knowledge that VE would likely be representing Northwest and after
    it had hired Baker & Botts.         These alleged facts, if accepted as
    true,   might   establish    that   American's     efforts   were    motivated
    primarily by a desire not to secure representation from VE, but to
    ensure that VE would not, or could not, represent Northwest.
    American, of course, contests Northwest's account, insisting
    that it had no knowledge of VE's prior commitment to Northwest and
    that it hired Baker & Botts on June 11, only after it was informed
    that VE would be representing Northwest.          When American learned of
    VE's    commitment   to   Northwest   is    a   factual    issue   crucial   to
    determining whether American sought VE's representation in good
    faith, as Texas Rule 1.06 requires.             The district court made no
    factual findings on this issue.            We need not remand for further
    fact finding because we hold that VE must be disqualified on other
    grounds.
    V
    American's    final   two    contentions     rest     on    VE's   prior
    representations of the airline in antitrust matters.                  American
    contends that VE must be disqualified because VE has represented
    American in matters substantially related to the present case and
    VE's representation of Northwest in this case will likely involve
    the use to American's disadvantage of confidential information
    obtained during this earlier representation. We will first discuss
    18
    the applicable      ethical     standards.     We    will   then   apply   these
    standards to the prior representations alleged by American to
    warrant VE's disqualification.
    A.
    American contends that VE's prior representations of American
    make disqualification appropriate under this court's precedents and
    the Texas Rules.        Our review in previous cases involving prior
    representations has been governed by the "substantial relationship"
    test:
    A party seeking to disqualify opposing counsel on the
    ground of a former representation must establish two
    elements:   1) an actual attorney-client relationship
    between the moving party and the attorney he seeks to
    disqualify and 2) a substantial relationship between the
    subject matter of the former and present representations.
    Johnston v. Harris County Flood Control Dist., 
    869 F.2d 1565
    , 1569
    (5th Cir. 1989); In re Corrugated Container Antitrust Litigation,
    
    659 F.2d 1341
    , 1345 (5th Cir. 1981); Duncan v. Merrill Lynch,
    Pierce, Fenner & Smith, 
    646 F.2d 1020
    , 1028 (5th Cir.), cert.
    denied, 
    454 U.S. 895
    (1981).           Because it is not disputed that VE
    represented American in the matters under consideration, the sole
    issue is whether these prior representations are substantially
    related to the present case.           Our inquiry may be narrowed to this
    single   question    because     the   substantial    relationship    test   is
    governed by an irrebuttable presumption.             Once it is established
    that the prior matters are substantially related to the present
    case,    "the   court    will     irrebuttably      presume    that   relevant
    confidential information was disclosed during the former period of
    19
    representation." 
    Duncan, 646 F.2d at 1028
    ; 
    Corrugated, 659 F.2d at 1347
    .1
    The test is categorical in requiring disqualification upon the
    establishment      of    a     substantial      relationship       between    past    and
    current representations.           But we have never applied the test in a
    mechanical    way       that    might    "prevent[]      an   attorney       from    ever
    representing an interest adverse to that of a former client."
    
    Duncan, 646 F.2d at 1027-28
    .              Rather, a substantial relationship
    may   be   found    only       after    "the    moving     party    delineates       with
    specificity the subject matters, issues and causes of action"
    common to prior and current representations and the court engages
    in a "'painstaking analysis of the facts and precise application of
    precedent.'"       
    Duncan, 646 F.2d at 1029
    (quoting Brennan's, Inc. v.
    Brennan's Restaurants, Inc., 
    590 F.2d 168
    , 174 (5th Cir. 1979)).
    Finally, the party seeking disqualification bears the burden of
    proving    that      the       present    and      prior      representations         are
    substantially related.           
    Duncan, 646 F.2d at 1028
    .
    This circuit adopted the substantial relationship test before
    the promulgation of the Rules of Professional Conduct.                         We must
    decide the application of the substantial relationship test under
    these new Rules.         Texas Rule 1.09 provides in relevant part:
    (a) Without prior consent, a lawyer who personally has
    formally represented a client in a matter shall not thereafter
    represent another person in a matter adverse to the former client:
    1
    A second irrebuttable presumption is that confidences
    obtained by an individual lawyer will be shared with the other
    members of his firm. See 
    Corrugated, 659 F.2d at 1346
    . This
    presumption is not at issue in this case, for all of the VE
    lawyers involved have previously represented American.
    20
    . . .
    (2)       if the representation in reasonable probability
    will involve a violation of Rule 1.05; or
    (3)       if it is      the    same   or    a    substantially       related
    matter.
    Rule 1.09(a)(2) incorporates Rule 1.05, which prohibits a lawyer's
    use of confidential information obtained from a former client to
    that former client's disadvantage.                    Rule 1.09 thus on its face
    forbids a lawyer to appear against a former client if the current
    representation in reasonable probability will involve the use of
    confidential information or if the current matter is substantially
    related to the matters in which the lawyer has represented the
    former client.2
    In providing two distinct grounds for disqualification, the
    Rules expand the protections for former clients beyond those
    afforded by the substantial relationship test.                     The Rules are not,
    however, broader than the protections provided by our precedents.
    While    the    focus   of    our    cases      has    been   on    the    substantial
    relationship test, we have indicated that a former client could
    2
    ABA Rule 1.9 is identical to Texas Rule 1.09 in all
    important respects:
    (a) A lawyer who has formally represented a client in a
    matter shall not thereafter represent another person in
    the same or a substantially related matter in which
    that person's interests are materially adverse to the
    interests of the former client unless the former client
    consents after consultation
    . . . .
    (c) A lawyer who has formally represented a client in a
    matter . . . shall not thereafter:
    (1) use information relating to the representation to the
    disadvantage of the former client . . . .
    ABA Rule 1.9.
    21
    also   disqualify   counsel   by   showing    that    his   former      attorney
    possessed    relevant   confidential        information     in    the     manner
    contemplated by Rule 1.09(a)(2).          As Duncan, for example, stated:
    "[The moving party may disqualify counsel on the basis of prior
    representations]    either    by   establishing      that   the   present    and
    previous representations are substantially related or by pointing
    to specific instances where it revealed relevant confidential
    information regarding its practices and procedures."              
    Duncan, 646 F.2d at 1032
    .    Thus, it does not appear that the Texas Rules make
    material addition to the basic approach we have used in the past.
    But do the Rules take something away?          That is, do the Rules
    offer less protection to former clients than our precedents?
    Northwest offers two related arguments on this score.                     First,
    Northwest contends that a substantial relationship between past and
    current matters exists only where the two cases are so closely
    related that the risk of adverse use of the former client's
    confidences threatens to "taint" the trial.           Northwest also argues
    that a close relation between a past and current representation is
    irrelevant if the attorney relied on publicly available information
    in advising the former client.       These two arguments are rooted in
    Northwest's larger assertion that the substantial relationship test
    is solely concerned with protecting a former client's confidences.
    Northwest offers three distinct grounds in support of its
    "taint" standard.    It first makes a brief attempt to locate this
    more demanding standard in Duncan.         According to Northwest, Duncan
    provides that a party may establish a substantial relationship
    22
    between past and current representations only by demonstrating that
    the two matters are so closely related that there is a "genuine
    threat that confidences revealed to his former counsel will be
    divulged to his present adversary."                 
    Duncan, 646 F.2d at 1028
    .
    Duncan, however, stands for a different proposition, for we held
    that    a   "genuine      threat"    of    adverse      use     of     confidences       is
    established by showing that a prior representation is substantially
    related to the present case. 
    Id. Under Duncan,
    a party demonstrates
    a "genuine threat" by establishing a substantial relationship
    between past and present cases, not, as Northwest would have it,
    the other way around.
    Northwest's other two arguments rest on its interpretation of
    Texas   Rule     1.09's    substantial      relationship           language.       First,
    Northwest      contends     that    the    commentary         to     Rule   1.09    makes
    "abundantly      clear"     that    the    Rule's      substantial          relationship
    language    is    directed    to    "actual      and   genuine        threats      to   the
    integrity of the trial process."            Comment 8 to Rule 1.09 provides:
    Although not required to do so by Rule 1.05 or this Rule,
    some courts, as a procedural decision, disqualify a
    lawyer for representing a present client against a former
    client when the subject matter of the present
    representation is so closely related to the subject
    matter of the prior representation that confidences
    obtained from the former client might be useful in the
    representation of the present client. See Comment 17 to
    Rule 1.06.
    Comment 17 provides that alleged conflicts should be raised by an
    opposing party only where the alleged "conflict is such as clearly
    to   call in     question    the    fair    or   efficient         administration        of
    justice."      Northwest concludes that this commentary reveals that
    23
    "the substantial relationship language of Rule 1.09 is bottomed on
    a concern about the actual fairness of the proceedings in which
    disqualification is sought."
    Northwest     also    contends       that    the    Texas       Rules'    conscious
    omission of the "appearance of impropriety" standard contained in
    Canon 9 of the Model Code independently establishes "taint" as the
    appropriate disqualification standard.                  Northwest points out that
    some of our broader substantial relationship cases, notably In re
    Corrugated Container Antitrust Litigation, 
    659 F.2d 1341
    (5th Cir.
    1981),   were    decided       under    Canon    9.      Northwest         asserts   that
    Corrugated's broad language was intimately tied to Canon 9's
    "appearance of impropriety" standard.                     Since the Texas Rules
    eliminated this rule, "disqualification is no longer appropriate
    unless counsel's continued involvement threatens to taint the
    underlying trial:          a mere appearance of impropriety will not
    suffice."
    We reject both of Northwest's arguments.                    A party seeking to
    disqualify counsel under the substantial relationship test need not
    prove that the past and present matters are so similar that a
    lawyer's    continued     involvement       threatens      to    taint        the   trial.
    Rather, the former client must demonstrate that the two matters are
    substantially related.               Second, we adhere to our precedents in
    refusing    to   reduce        the    concerns    underlying         the    substantial
    relationship     test     to    a     client's   interest       in    preserving       his
    confidential information. The second fundamental concern protected
    by the test is not the public interest in lawyers avoiding "even
    24
    the appearance of impropriety," but the client's interest in the
    loyalty of his attorney.
    Northwest's argument that the Texas Rules' commentary bottoms
    Rule 1.09's substantial relationship language on a concern for
    "actual fairness" rests on its general interpretation of the Texas
    Rules.        Northwest     suggests    that       courts'       use   of    disciplinary
    standards in disqualification matters is "understandable in courts
    that    have    not   yet    developed        their       own    specific      procedural
    disqualification rules or standards."                    Courts may borrow from the
    rules, with two important qualifications: "First, any violation of
    a disciplinary standard must be demonstrated by movant to have been
    actually prejudicial          to    movant;       and,    second,      disqualification
    should be denied unless the litigation will be 'tainted' by the
    continued participation of a lawyer or firm that may have violated
    a disciplinary standard."
    This    argument     is     closely    related       to    Northwest's      larger
    assertion that the Texas Rules are "guides" for courts and are not
    to be "literally" applied in disqualification cases. We addressed,
    and rejected, this general argument in Part III.                            We understand
    this particular argument concerning the substantial relationship
    test to be something more than a reiteration of this general point.
    Northwest's initial argument was that a breach of an ethical
    standard does not by itself require disqualification; an additional
    showing of taint is needed.             Here, Northwest appears to concede
    that such a breach requires disqualification, but asserts that the
    rule barring representation in substantially related matters is not
    25
    violated unless the cases are so similar that there is a genuine
    threat of taint.     We reject this argument.      The substantial
    relationship test, as applied in this circuit and elsewhere, does
    not have its source in disciplinary rules.     To the contrary, the
    test was developed at common law.    Our precedents did not rely on
    the Model Code or Model Rules in formulating the substantial
    relationship test, but on the landmark T.C. Theatre Corp v. Warner
    Bros. Pictures, Inc., 
    113 F. Supp. 265
    (S.D.N.Y. 1953), which
    predated the Model Code and of course the Model Rules. See, e.g.,
    Wilson P. Abraham Construction Corp. v. Armco Steel Corp., 
    559 F.2d 250
    , 252 (5th Cir. 1977); In re Yarn Processing Patent Validity
    Litigation, 
    530 F.2d 83
    , 89 (5th Cir. 1976).
    The actual development of Rule 1.09's substantial relationship
    provision is the just the opposite of the version Northwest gives.
    The initial drafts of both the ABA and Texas Rules did not include
    a rule barring representation in substantially related matters. In
    both cases, the substantial relationship rule was added as a
    reflection of case law.   See Robert P. Schuwerk & John F. Sutton,
    Jr., A Guide to the Texas Disciplinary Rules of Professional
    Conduct, 27A Hous. L. Rev. 1, 152 n.20, 153 n.34 (1990); Note, In
    Defense of the Double Standard in the Rules of Ethics: A Critical
    Reevaluation of the Chinese Wall and Vicarious Disqualification, 20
    U. Mich. J.L. Ref. 245, 257 & n.66 (1986) (ABA Rules).   Schuwerk &
    Sutton's account is instructive:
    [T]he Texas committee originally avoided [the substantial
    related matter language] in proposed Texas Rule 1.09 . .
    . . Subsequently, however, a difficulty emerged as a
    result of failure to employ the substantial relationship
    26
    test in a disciplinary context. A lawyer might accept or
    continue employment in a matter against a former client
    believing (correctly) that no disciplinary violation was
    involved under the initially proposed version of Rule
    1.09, only to be disqualified subsequently--perhaps at
    great cost and expenses to the client--by a court
    employing the traditional substantial relationship test
    . . . . The drafting committee, therefore, concluded
    that the danger of having its narrowly drawn Rule 1.09
    turn into a trap for the unwary outweighed its objections
    to the substantial relationship test as a standard of
    discipline. It would be in keeping with the committee's
    thinking, however, to construe "substantially related"
    narrowly for disciplinary purposes.
    Schuwerk & 
    Sutton, supra, at 153
    n.34 (emphasis added); see also
    Rule 1.09 Comment 9.
    As this account suggests, the difficulty posed by Rule 1.09
    does not concern the "literal and mechanical" application of a
    disciplinary rule in disqualification cases.       Rather, the concern
    is the transfer of the substantial relationship test developed by
    courts to the disciplinary context.      See also Charles W. Wolfram,
    Modern Legal Ethics 366 (1986) (discussing ABA Rules' "adoption of
    the substantial relationship standard as a disciplinary rule").
    Contrary to Northwest's contentions, the Rules did not supplant,
    but adopted, the common law substantial relationship test.          The
    argument thus provides no basis for applying the substantial
    relationship test through the "taint" filter it proposes.
    Northwest's argument concerning the Rules' deletion of Canon
    9's   appearance   of   impropriety    standard   has   more   purchase.
    Northwest argues that the Model Rules' omission of the "appearance
    of impropriety" standard contained in the Model Code indicates that
    the substantial relationship test should be solely concerned with
    ensuring "actual fairness" in the proceedings.      But Northwest does
    27
    not mention loyalty, itself a substantial addition under the Rules.
    As several commentators have noted, the Model Code provided no
    express protection to the former client's interest in loyalty.
    See, e.g., Geoffrey C. Hazard & W. William Hodes, The Law of
    Lawyering 292 (1991); 
    Wolfram, supra, at 363
    (1986). This interest
    is singled out only under the Rules.       See Texas Rule 1.06 Comment
    1 ("Loyalty is an essential element in the lawyer's relationship to
    a client"); ABA Rule 1.9 Comment ("The second aspect of loyalty to
    a   client   is   the   lawyer's   obligation   to   decline   subsequent
    representations involving positions adverse to a former client
    arising in substantially related matters"); Hazard & 
    Hodes, supra, at 292-93
    ; 
    Wolfram, supra, at 361
    ; 
    Sutton, supra, at 147

    Gillers, What We Talked About When We Talked About Ethics: A
    Critical View of the Model Rules, 46 Ohio St. L.J. 243, 250-55
    (1985).
    The    Rules'     express    establishment     of   loyalty    and
    confidentiality as the interests protected by the substantial
    relationship test is a return to T.C. Theatre Corp. v. Warner Bros.
    Pictures, Inc., 
    113 F. Supp. 265
    , 268-69 (S.D.N.Y. 1953), where the
    court held that once it is established that the two representations
    are substantially related,
    [t]he court will assume that during the course of the
    former representation confidences were disclosed to the
    attorney bearing on the subject matter of the
    representation. It will not inquire into their nature
    and extent. Only in this manner can the lawyer's duty of
    absolute fidelity be enforced and the spirit of the rule
    relating to privileged communications be maintained.
    
    Id. (emphasis added).
    28
    We believe the replacement of the "appearance of impropriety"
    with   loyalty    provides    no   basis   for   altering     the   substantial
    relationship test found in our precedents. This is because we read
    our cases involving Canon 9 as protecting the same interest in
    loyalty now explicitly provided for under the Rules.                     As the
    Comment to ABA Rule 1.9 notes, "[r]epresentation adverse to a
    former client was sometimes dealt with under the rubric of Canon 9
    of the Model Code."    This was true of this court as well as others.
    The link between loyalty and the appearance of impropriety is
    most evident in Brennan's Inc. v. Brennan's Restaurants, Inc., 
    590 F.2d 168
    (5th Cir. 1979), where the court disqualified a former
    counsel    even   though     there   was   no    chance    that     confidential
    information might be used against the former client.                We held:
    The obligation of an attorney not to misuse information
    acquired in the course of representation serves to
    vindicate the trust and reliance that clients place in
    their attorneys.    A client would feel wronged if an
    opponent prevailed against him with the aid of an
    attorney who formerly represented the clients in the same
    matter. As the court recognized in E.F. Hutton & Co. v.
    Brown, 
    305 F. Supp. 371
    , 395 (S.D. Tex. 1969), this would
    undermine public confidence in the legal system as a
    means for adjudicating 
    disputes. 590 F.2d at 172
    .      As Professors Hazard and Koniak observe: "In
    Brennan's, the Court recognizes two underlying concerns of the
    substantial relationship test:         the duty to preserve confidences
    and the duty of loyalty to a former client."              Geoffrey C. Hazard &
    Susan P. Koniak, The Law and Ethics of Lawyering 658 (1990).                   See
    also E.F. Hutton & Company v. Brown, 
    305 F. Supp. 371
    , 395 (S.D.
    Tex. 1969) ("If courts protect only a client's disclosures to his
    attorney, and fail to safeguard the attorney-client relationship
    29
    itself--a relationship which must be one of trust and reliance--
    they can only undermine the public's confidence in the legal system
    as a means for adjudicating disputes."); 
    Duncan, 646 F.2d at 1027
    ("the integrity of the judicial system would be sullied if courts
    tolerated such abuses by those who profess and owe undivided
    loyalty to their clients") In re Yarn Processing Patent Validity
    Litigation,   
    530 F.2d 83
    ,   90   (5th    Cir.   1976)   (prohibition   of
    representation of conflicting interests rests on lawyers duties of
    loyalty and confidentiality); Cf. In re Corn Derivatives Antitrust
    Litigation, 
    748 F.2d 157
    , 161-62 (3d Cir. 1984); In re Agent Orange
    Product Liability Litigation, 
    800 F.2d 14
    , 17-18 (2d Cir. 1986).
    As these decisions suggest, the existence of a lawyer's duty
    of loyalty means that the substantial relationship test is not
    solely concerned with the adverse use of confidential information.
    What the duty of loyalty adds to the duty of confidentiality is
    clearly presented in Corrugated:
    Container's complaint is that the district court failed
    to explain how [the lawyer's] advice would be relevant or
    substantially related to this action. The advice does
    not need to be "relevant" in the evidentiary sense to be
    "substantially related." It need only be akin to the
    present action in a way reasonable persons would
    understand as important to the issues involved.
    
    Corrugated, 659 F.2d at 1346
    (emphasis added).
    We emphasize "advice" because a court solely concerned with
    the possible adverse use of confidential information might not be
    obliged to protect legal advice.           As at least one court has noted,
    "the concern of the Confidentiality Rule and the case law is the
    protection of what the client tells his attorney, not what the
    30
    attorney tells the client."               Laker Airways Ltd. v. Pan American
    World Airways, 
    103 F.R.D. 22
    , 40 (D.D.C. 1984) (emphasis added).
    We agree that the confidentiality rule was historically concerned
    with disclosures, but we are also persuaded that the substantial
    relationship test cannot be reduced to a confidentiality rule. See
    Texas Rule 1.07.          That is, because the substantial relationship
    test is concerned with both a lawyer's duty of confidentiality and
    his    duty    of    loyalty,       a   lawyer    who   has    given   advice     in    a
    substantially related matter must be disqualified, whether or not
    he has gained confidences.
    We agree with Northwest that the "appearance of impropriety"
    has no relevance to our probe of ethical restraints.                     It does not
    follow, however, that the focus of the substantial relationship
    test now becomes the "actual fairness" of the trial.                    Such a shift
    is    premised      on   the    view    that     eliminating    the    appearance      of
    impropriety reduces the substantial relationship test to a concern
    for confidential information.              We believe that such a reduction is
    precluded by a lawyer's duty of loyalty.                       Because Canon 9 was
    primarily interpreted by the court as a way to protect a client's
    loyalty       interests,       we   believe      that   our    application   of     the
    substantial relationship test under the Rules is the same as it was
    under the Code.
    We believe that disqualification of VE would be appropriate
    even under the relaxed "actual prejudice" or "taint" standard
    Northwest urges this court to adopt.                    As we explain below, the
    relationship between the matters in which VE has represented
    31
    American and the instant litigation is so intimate that VE's
    continued involvement does threaten to compromise the integrity of
    the present trial.           Our    continued adherence to the substantial
    relationship test rests on our belief that the ethical prohibition
    against    successive        representation       cannot   be     reduced      to   the
    protection of clients' confidences, let alone protecting these
    confidences only to the extent that their adverse use might "taint"
    the trial, as Northwest's proposal would provide.                            Rather, a
    lawyer's obligation of confidentiality must be seen as part of the
    lawyer's primary duty of loyalty, a duty that is not exhausted by
    the preservation of a former client's secrets.                   We believe that a
    single inquiry into whether past and present representations are
    substantially related provides the best means to protect these two
    interests of clients.
    Because it recognizes these two interests, the substantial
    relationship        test   serves   not    only   to   ensure    the    fairness     of
    particular trials, but also to safeguard the integrity of the
    attorney-client relationship. If the sole focus of the substantial
    relationship test was the possible adverse use of confidences,
    prior representations in which the attorney advised the client but
    received       no     confidential        information      would       not     warrant
    disqualification.          Even if the subject matter of case one and case
    two is identical, a former client's adversary is not inevitably
    advantaged by virtue of his attorney's prior representation of the
    client.    And yet this court has held that the provision of legal
    advice    on   a    substantially     related     matter    by    itself      requires
    32
    disqualification.       See 
    Corrugated, 659 F.2d at 1346
    -47; 
    Brennan's, 590 F.2d at 171-72
    .
    Disqualification        rules    not    only    preserve    the     purity   of
    particular trials but also unavoidably affect relationships among
    attorneys and clients in general.              This court bars attorneys from
    appearing in substantially related matters not only to protect
    individual parties against the adverse use of information but also
    "to aid the frank exchange between attorney and client."                    Wilson P.
    Abraham Const. Corp. v. Armco Steel Corp., 
    559 F.2d 250
    , 252 (5th
    Cir.    1977);    see   also    In   re   Yarn   Processing       Patent    Validity
    Litigation, 
    530 F.2d 83
    , 90 (5th Cir. 1976).                  A post hoc inquiry
    into whether a particular attorney's involvement in a particular
    suit might "taint" the case in no way provides the breadth and
    "predictability of confidence [that] is central to the role of the
    attorney."       In re LTV Securities Litigation, 
    89 F.R.D. 595
    , 602
    (N.D. Tex. 1981); cf. Upjohn Co. v. United States, 
    101 S. Ct. 677
    ,
    683-84 (1981) (recognizing that confidentiality is essential to
    frank    discussions     between       attorneys      and   clients   or    client's
    employees).       The trust a lawyer's duty of loyalty inspires in
    clients encourages them freely to confide in the lawyer and freely
    to rely on the advice provided by the lawyer.                     The substantial
    relationship test aims to protect the adversary process but also,
    or as part of this concern, seeks to provide conditions for the
    attorney-client relationship. As such, our central concern remains
    the application of the rule to the actual relationship of lawyers
    and clients, but in the process we consider also what they might
    33
    have done.     What    credence,       for   example,   might    American       have
    attached to VE's December 1990 counsel that the airline's interests
    would be better served by postponing the acquisition of Continental
    for at least a year if it even suspected that VE itself might soon
    be representing one of its competitors in a suit against American,
    charging that it had abused its market power to the detriment of
    competition in the airline passenger service markets?
    These considerations preclude us from accepting Northwest's
    final argument.    Northwest claims that because VE relied primarily
    on public, not confidential, information in advising American,
    these prior matters cannot be considered substantially related to
    the present case.      It contends that "'[f]acts that are community
    knowledge or that are not material to a determination of the issues
    litigated do not constitute "matters involved" within the meaning
    of the law' governing the substantial relationship test" (quoting
    J.K. & Susie L. Wadley Research Inst. & Blood Bank v. Morris, 
    776 S.W.2d 271
    , 278 (Tex. App.--Dallas 1989, orig. proceeding)).                     The
    record sharply contradicts Northwest's claim that all of the
    material obtained by VE was publicly available.                  As we discuss
    below, VE was privy to many of American's secrets.              But Northwest's
    argument   would   fail   even    if    it   could    show    that   all   of   the
    information   provided    by     American    was     public   knowledge.        Our
    precedents, the Texas Rules, and the ABA Rules all reject the
    position   Northwest      advances.          This     court    has    held      that
    "[i]nformation [provided by a client] is sheltered from use by the
    attorney against his client by virtue of the existence of the
    34
    attorney-client relationship.             This is true without regard to
    whether someone else may be privy to it."                     Brennan's, Inc. v.

    590 F.2d 168
    , 172 (5th Cir. 1979).
    "'This ethical precept       . . . exists without regard to the nature

    to be disclosed are part of a public record, or that there are

    Drinker, Legal Ethics 135 (1953); NCK Organization Ltd. v. Bregman,
    
    542 F.2d 128
    , 133 (2d Cir. 1976) (same).
    The Texas and ABA Rules supply the same standard.                   The Rules
    do contain an exception for public information, but in each case
    this exception applies only to the provision prohibiting the use of
    confidential       information,    not   the   rule     prohibiting      successive
    representation in substantially related matters.                 Texas Rule 1.05
    provides that "a lawyer shall not knowingly
    (3) [u]se confidential information of a former client to
    the disadvantage of the former client after the
    representation is concluded unless the former client
    consents   after  consultation   or   the   confidential
    information has become generally known."
    Texas Rule 1.05 (b) (3) (emphasis added). This provision, however,
    is   incorporated      by   Rule    1.09(a)     (2),     not    the     substantial
    relationship rule contained in Rule 1.09 (a) (3).                         The same
    35
    distinction exists between Rules 1.9 (a) and 1.9(c) of the ABA
    Rules, as commentators have indicated.            See, e.g., Charles W.
    Wolfram, Modern Legal Ethics 360, 365 (1986).
    We     believe    that   our   application    of   the   substantial
    relationship test under the Rules is the same as it was under the
    Code.     Thus, as in our past cases, our inquiry is limited to the
    single question of whether VE's prior representations of American
    are substantially related to the present case.
    B.
    VE represented American in several matters in recent years,
    earning fees in excess of $676,000.      Our review will be limited to
    three of VE's prior representations.       VE defended American in two
    suits brought by Continental in Texas.      The focus of each case, as
    in the larger California litigation to which they were related, was
    SABRE, American's computerized reservation system. The first case,
    System One Direct Access, Inc v. American Airlines Inc., was an
    antitrust suit brought by a Continental affiliate in Houston
    federal court.        VE served as counsel from November 1987 until
    withdrawing in July 1988 when the case was transferred to Dallas.
    VE also served as lead counsel in Continental Airlines, Inc.
    v. American Airlines, Inc., a Texas state court case.         Continental
    alleged that American had breached contractual relationships and
    committed other acts of misconduct in operating its CRS.               VE
    represented American from March 1989 until the case was settled as
    part of the global settlement between Continental and American in
    May 1990.
    36
    In late 1990, VE advised American concerning whether the
    Antitrust Division of the Department of Justice would approve
    "Project    Armadillo,"   a   proposed     acquisition    of    Continental
    Airlines.     The primary question was whether a merger of the two
    airlines would run afoul of the Department's merger guidelines.
    The representation ended in January 1991, when American apparently
    chose not to pursue the merger.
    The two Texas cases were related and subsidiary to a larger
    suit by Continental and Northwest, among others, against American
    and United Airlines in California federal district court in 1985.
    Continental    and   Northwest   charged    American     and   United   with
    monopolization of both computerized reservation systems and various
    air transportation markets.3 In particular, they charged predatory
    pricing of CRS systems and air transportation, closely related to
    the claim advanced by Northwest and Continental here.
    American asserts, and Northwest appears to concede, that the
    California case is substantially related to the present case.
    However, Gibson, Dunn & Crutcher, not VE, represented American in
    California, so the similarities between the California case and the
    present one are no basis for disqualification. American's argument
    that VE's prior representations are substantially related to this
    case rests largely then upon its claim that the Texas cases are
    substantially related to the California case.

    37
    Northwest argues that the Texas cases are not substantially
    related to this case because the allegations in these cases, unlike
    in   California,     pertained    only      to    CRS    services,       not     air
    transportation     services.     We    disagree.        While    the    focus    was
    certainly CRS systems, the plaintiffs also raised claims involving
    air transportation markets.           Moreover, as we will explain, the
    Texas cases involved two particular matters at issue in the present
    case.

    Fort   Bend   involved    the    state-law     claims      over    which    the
    California district court, upon American's motion to dismiss, had
    declined to exercise pendent jurisdiction.               Continental alleged
    breach      of     contract,      duress,         tortious        interference,
    misrepresentation, and violation of the Texas Deceptive Trade
    Practices Act. As in California, Continental's petition focused on
    American's CRS operations.       But also as in California, Continental
    asserted that American's power in the CRS market could not be
    considered apart from its position in the air transportation
    market.     Continental   claimed       that     "American      and    United,    by
    leveraging their dominance as air carriers and the enormous secret
    profits they received from bias-diverted revenues, established
    themselves as the dominant CRS providers."               Continental charged
    that American, having achieved dominance in the CRS market, in turn
    used SABRE to "exclude[] Continental in whole or in part from
    specific airline passenger markets."
    38
    Continental's      claims    were      stated   in    a     similar    manner.
    Continental claimed that American had breached its contract by
    "secretly accessing TXI's [a Continental affiliate] data base and
    using it to study passenger traffic flow through the Dallas/Fort
    Worth hub.     Reports developed by American through the use of the
    TXI data contributed to American's successful exclusion of TXI from
    the   Dallas/Fort   Worth    hub    and      elsewhere."        In   its    tortious
    interference     claim     Continental        alleged      that      American    had
    "interfered with Continental's prospective contractual relations
    with its travel agents and air passengers," causing damages in the
    form of "lost airline bookings through bias diversions and total
    exclusion    from   certain       air     passenger     markets."           Finally,
    Continental noted that the California district court had cited
    American President Robert Crandall's alleged 1982 price-fixing
    solicitation of Braniff as "a textbook example of anticompetitive
    conduct" in ruling that "Continental could proceed to trial on its
    claim that American illegally attempted to monopolize the Dallas-
    Fort Worth airport."
    Continental's allegations and its reference to Crandall's
    alleged price-fixing solicitation apparently supplied the basis for
    the belief among VE and Gibson, Dunn lawyers that American's
    alleged attempted monopolization of DFW would be at issue in the
    case and that Continental might seek to introduce the price-fixing
    incident as evidence on this score.             As such, they believed that
    Fort Bend was intimately related to the California case.                         For
    example, a VE partner stated at the time that the California and
    39
    Fort Bend suits "involve the same parties, the same alleged acts,
    and the same alleged damages."        Another VE lawyer noted that the
    two suits could be seen as "largely identical":              "[The Fort Bend
    petition]   asserts   that    AA   and   UA   used   their     purported    CRS
    monopolies to obtain monopoly power in certain air transportation
    markets.       This   claim   is    intertwined      with    both    the    CRS
    monopolization and DFW attempted monopolization claims pending in
    California."    The perceived similarities between Fort Bend and the
    California case led VE and Gibson, Dunn to spend considerable time
    exploring the possibility of an abatement of the Fort Bend case
    until the California proceedings had concluded.
    VE argues that Crandall's alleged price-fixing solicitation
    and Continental's claim that American had used its CRS to exclude
    it from the DFW market were not at issue in Fort Bend.                     This
    contention is contradicted by the accounts of Gibson, Dunn lawyers
    and by notes taken by a VE lawyer during one meeting between VE and
    Gibson, Dunn.    While it is difficult to reconstruct a conversation
    from this distance, we are struck by the first two comments on the
    first page of notes:     1) "There is no admissible evidence of the
    Crandall telephone     conversation      on   Braniff;   may   use   it    on a
    consequential damages theory that Continental excluded from DFW
    market."    2) "We should argue that the exclusion claim is being
    litigated in California and should not be litigated in Texas."
    Given the allegations in the complaint, the statements of VE's
    lawyers at the time, and this evidence it is difficult to maintain
    that these matters were not at issue in Fort Bend.
    40
    The charges of monopolization of DFW and Crandall's alleged
    solicitation    are   prominently    featured   in    Northwest's   current
    complaint.     Northwest alleges that American has monopolized or
    attempted to monopolize five different air transportation markets.
    Dallas-Fort Worth is included as an "illustrative example" in three
    of the five markets cited by Northwest:           origin and destination
    city pair markets, O & D airport-airport pair markets, and O & D-
    based hub markets.     It cannot be denied that one focus of the case
    will be American's DFW operations, the very market at issue in Fort
    Bend.
    Similarly, Northwest contends in its complaint that "AA and
    its current chief executive officer have previously engaged in
    anticompetitive conduct with open contempt for the antitrust laws."
    Northwest    prominently     cites   Crandall's      alleged   price-fixing
    solicitation, the same allegation that VE lawyers were charged with
    excluding in the Fort Bend case.          VE suggested at oral argument
    that Crandall's alleged solicitation is not substantially related
    to the present case because this ten-year old incident would not be
    admitted as evidence.      This is helpful but not dispositive.      As the
    Corrugated court stated, the subject matter "does not need to be
    'relevant' in the evidentiary sense to be 'substantially related.'
    It need only be akin to the present action in a way reasonable
    persons would understand as important to the issues involved."
    
    Corrugated, 659 F.2d at 1346
    .         Northwest included the incident
    under the heading "Conduct Giving Rise to Violations Alleged" in
    its complaint. This is not easily explained away, especially given
    41
    Northwest's   heavy    reliance   on   the   location   of   the   Crandall
    allegation in the Fort Bend petition's "procedural history" in
    attempting to prove that the incident was not at issue in that
    case.
    We are persuaded that VE's representation of American in the
    Fort Bend case is substantially related to the present case.
    2)   System One
    In System One, Continental affiliate System One, a CRS vendor,
    charged that American had violated antitrust laws in its provision
    of CRS services.      System One alleged that American had engaged in
    a variety of acts designed to exclude it from the CRS market.           But
    as in Fort Bend, plaintiff presented the CRS and air transportation
    markets as inextricably linked.        The System One complaint alleged
    that "AA has used its monopoly power in the provision of air
    carrier services in various geographic markets to obtain, retain,
    and enhance its power in the provision of CRS systems." Again, "AA
    has achieved its dominant position in the market for CRS services,
    and continues to enforce anticompetitive practices in an effort to
    maintain that position, not only to reap monopoly profits from the
    sale and use of CRS systems, but to enhance profits from the
    provision of air transportation services."
    The record reflects extensive discovery regarding SABRE's
    effects on air transportation revenues.        System One requested all
    documents relating to the "incremental revenues," the general
    effect of "airline ownership of a CRS on the airline's sale of air
    transportation services," and "any actual or possible loss of
    42
    revenue or other detriment to any commercial air carrier as a
    result of the operation or installation of SABRE."           In response,
    American agreed to produce all documents "that discuss, study, or
    analyze whether, and the extent to which, any airline (including
    American) which owns a CRS obtains incremental airline revenue as
    a consequence of automating travel agencies with its CRS" as well
    as "documents discussing whether American has a 'premium share' of
    the traffic in a particular region or market and whether this is
    attributable to the presence of SABRE in that region or market."
    In the absence of this prior litigation, there is little doubt
    that Northwest would seek to introduce evidence of the incremental
    revenues generated by SABRE in support of the predatory pricing
    claims it    raises    in   this   case.    Northwest's   General   Counsel
    recently    asserted   in   congressional    testimony    that   American's
    ability
    to restructure and reduce its fares dramatically is
    directly related to American's long-term, advantageous
    use of its CRS . . . .      DOT studies repeatedly have
    documented the flow of hundreds of millions of dollars of
    incremental revenue diverted from other carriers to
    American and United as a result of their CRS market power
    . . . [I]n a very real sense, American has launched its
    predatory attack on the industry using our own money.
    It is the case that challenges by Northwest and Continental of
    American's CRS use have been earlier terminated in ways restricting
    their present assertion, Continental by settlement and Northwest by
    a final judgment.      Pointing to these outcomes, VE states that it
    will not, because it cannot, raise any issues relating to CRS in
    this case.     Any attempts to redress perceived CRS abuses by
    American will be confined, as the congressional testimony suggests,
    43
    to the legislature.      Since American's CRS operation will not be at
    issue, VE contends that its representation of American on this
    matter cannot be substantially related to this case.                   Northwest in
    particular claims that the issues of incremental revenue and costs
    addressed in System One relate to CRS use and are quite different
    from the general airline revenue and cost issues at the center of
    this case.
    We recognize that several possible claims relating to CRS
    might be barred by res judicata and we do not question Northwest's
    representations in this court and below that the present litigation
    will involve no attacks on American's CRS use.                         We are not
    persuaded,    however,     by     Northwest's       argument    that    a   party's
    representation that matters in which a lawyer represented a former
    client cannot, or will not, be introduced in the present case
    precludes a court from finding these matters substantially related
    to the prior representations.          The exact scope of categories such
    as "CRS matters," especially at the early stage of the litigation
    when motions to disqualify are often considered, is unclear, and
    leaves much room for good faith dispute among the parties.                        The
    party who either lost in the previous case or represented to the
    court that certain matters will not be raised will attempt to
    define the sphere of these issues narrowly, while the party who
    prevailed    in   the      earlier     case    or     filed    an     unsuccessful
    disqualification    motion      will   naturally      attempt    to     define    the
    precluded matters quite broadly. In the particular case of res
    judicata,    it   places    the    former     counsel    in    the     position    of
    44
    attempting      to   minimize    the    beneficial   results      of    her   prior
    representations by limiting their effect in the present case.
    The facts of this case disclose how such a dispute might
    arise.    Northwest claims that System One involved the particular
    matter    of    incremental     revenues      obtained   by   American    through
    ownership of a CRS.       Northwest states that the focus in this case
    will be on wholly different matters such as American's marketing
    strategy, ticket pricing, and general airline costs and revenues.
    The    line    between   incremental     revenues    and      general   revenues,
    however, does not appear as distinct as VE suggests.                    Moreover,
    American hotly disputes VE's contention that discovery in System
    One was limited to the narrow issue of incremental revenues.                     To
    the contrary, American asserts that the VE lawyers reviewed and
    discussed documents relating to marketing strategy and general air
    transportation revenues and costs, the very matters Northwest
    identifies as the heart of the instant case.
    There is another matter involved in System One that Northwest
    has indicated will be at issue in this case.             Northwest must focus
    at trial upon barriers to entry into the relevant markets.                    In its
    complaint, Northwest lists among these barriers "the role of travel
    agents in the industry and incentive commissions paid by airlines
    to    travel   agents    and    other   marketing    programs     and   devices."
    Incentive or override commissions in particular were at the center
    of the System One case.
    System One charged that American used override commissions as
    a means to exclude it from the CRS market:                 "AA conditioned the
    45
    payment to travel agents of commissions on AA ticket sales on their
    agreement to use the SABRE system."           As System One explained, this
    arrangement worked especially well in those areas where American
    was the dominant air carrier.               In connection with this claim,
    American agreed to produce and searched for "[d]ocuments that
    describe or discuss American's policies and procedures regarding
    participation by travel agencies in any override, special incentive
    or 'soft dollar' commission program offered by American." American
    asserts, and Northwest does not appear to contest, that VE lawyers
    reviewed much of this material.               A VE lawyer and several VE
    paralegals      spent   more   than   ten    weeks   reviewing   documents   at
    American's offices.       Gibson, Dunn lawyers who were involved claim
    that   a   VE   lawyer    personally    reviewed     documents    relating   to
    marketing strategy and air transportation issues.                The materials
    submitted with the Gibson, Dunn affidavits provide additional
    support for these claims.       VE's description of its work on the case
    does little to contradict these accounts.            Its response is limited
    to a statement by the lawyer that he has no specific recollection
    of documents reviewed and that he does not believe, "given the
    nature of the case," that he "reviewed any documents relating to
    American's pricing of airline transportation."
    Northwest contends that the presence of the issue of override
    commissions in System One and the instant case does not make the
    two representations substantially related.             Northwest argues that
    the two cases are not related because in System One the commissions
    were alleged to be a barrier to entry into the CRS market, while
    46
    here they represent a barrier to entry into the air transportation
    market.      Regardless of the direction of the block the trial must
    focus on the exclusionary force of CRS--its power to exclude
    competition in CRS is the handmaiden of its exclusionary force on
    airline passenger service.
    We        therefore     find     Northwest's     purported        distinction
    unavailing. Corrugated and Duncan provide that two representations
    need    only      involve     the   same   "subject   matter"    in   order   to    be
    substantially related.              See 
    Corrugated, supra
    ; 
    Duncan, supra
    .           As
    the summary of the document request quoted above discloses, VE
    lawyers reviewed documents relating to travel agency commissions in
    general, not simply those documents referring to the alleged
    practice of tying such commissions to CRS use.                        A substantial
    relationship exists when the prior representation concerns "the
    particular practices and procedures which are the subject matter of
    [Northwest's] suit.           
    Duncan, 646 F.2d at 1032
    .        Both System One and
    the    present      case     involve   American's     travel    agency   commission
    "practices and procedures."             Given that the two cases sharing this
    "subject matter" allege similar antitrust violations, we find VE's
    representation of American in System One substantially related to
    its present representation of Northwest.
    3)        Project Armadillo
    VE represented American most recently in "Project Armadillo,"
    an American proposal to acquire Continental.               VE provided American
    with antitrust analysis of the proposal, focusing on whether a
    merger      of    the   two   airlines     could   avoid   challenge      under    the
    47
    Department   of   Justice   antitrust   merger      guidelines.      VE's
    representation began in late November 1990 and concluded in early
    January 1991, when American chose not to pursue the acquisition.
    As a memorandum prepared by American explained, the Department
    of Justice merger guidelines' main concern is "whether the merger
    will likely create, enhance or facilitate the exercise of market
    power--the ability to raise prices to supracompetitive levels--by
    the remaining participants in the relevant market."         Market power
    is more easily inferred under narrowly defined markets, and it was
    therefore in American's interest to avoid "[a] market definition
    that is improperly narrow," for this would "result in such a high
    level of concentration that, inevitably, a court will conclude the
    merger poses an incipient threat to competition."
    These same issues are at the heart of the present case.
    Northwest alleges that American has monopolized or attempted to
    monopolize the national air transportation market as well as four
    smaller   geographic   markets   involving   city   pairs   and   regions.
    Because American enjoys a greater share of particular regional
    markets, Northwest will no doubt attempt to prove at trial that
    these smaller markets are relevant.     To this end, Northwest cites
    four instances where American has allegedly indicated that O & D
    and regional passenger markets are relevant markets.
    VE asserts that its "narrow, limited, and brief" role in
    Project Armadillo cannot serve as the basis for disqualification in
    the present case.   Northwest contends that some VE lawyers alleged
    by American to have worked on Project Armadillo were not in fact
    48
    involved.       A VE memorandum summarizing the initial meeting between
    American and VE lawyers, however, includes a notation directing
    that a copy of the memo be sent to these same lawyers whose
    involvement in the matter VE denies.                Similarly, VE attempts to
    minimize    the    significance       of   the    materials      it    received     from
    American by suggesting that the materials were not even read by
    certain VE lawyers involved in the representation.                         The billing
    statements submitted by VE to American, however, disclose that each
    of   the   VE    lawyers     in    question     devoted   time    to       "review[ing]
    materials furnished by [the] client."
    We have no reason to suggest that VE's misstatements are other
    than oversights, and, because they pertain only to the degree of
    its involvement in Project Armadillo, are secondary to the main
    question of the subject matter of VE's representation.                        Northwest
    contends that VE's representation of American does not warrant
    disqualification for two related reasons.                 Northwest asserts that
    VE was charged with a single "narrow, straightforward question" to
    which the answer was "obvious":                  Would the Justice Department
    oppose a complete merger of Continental and American on antitrust
    grounds?    Northwest claims that the problem posed to VE required
    little detailed analysis and that all the information needed by VE
    to reach its conclusion "was and is publicly available."                        Because
    VE required no confidential information to determine that the
    merger would not be approved by the Justice Department, Northwest
    contends    that      VE's        representation     provides         no    basis   for
    disqualification.
    49
    The record sharply contradicts Northwest's claim that all of
    the material supplied by American to VE was publicly available. But
    Northwest's argument would fail even if it could show that all of
    the information    provided   by   American    was    a   matter    of   public
    knowledge.   As we explained above, the substantial relationship
    test, as set out in our precedents and the Rules, contains no
    exception for prior representations in which an attorney's advice
    was based on public information.        Accordingly, the question is not
    whether   VE's   representation    of    American    in   Project   Armadillo
    involved matters of public knowledge but whether the subject matter
    of the prior representation is substantially related to the present
    case.
    American argues that the primary issue in Project Armadillo,
    as in this case, was market definition.        Not only did VE represent
    American on this same issue, but VE was also in a position to
    obtain information regarding American's views on the proper measure
    of markets, views which Northwest's complaint suggests are relevant
    to the present case.    Northwest recognizes that market definition
    will be crucial in this case, but argues that VE's treatment of
    this issue in Project Armadillo was superficial and limited. While
    conceding that "[m]ore difficult questions could have been raised
    had American been interested in a partial acquisition," Northwest
    contends that the "only issue with which American was concerned was
    whether it would be challenged if it attempted to acquire all of
    Continental's operations."    According to Northwest, "[t]he answer
    to American's question was obvious . . .             Anyone familiar with
    50
    American's hub operations in Dallas and Continental's Houston hub
    operations would realize that American and Continental are major
    competitors in this region and that their combination would be
    subject to challenge."
    The record demonstrates, however, that the subject matter was
    far more complex, and VE's analysis far more extensive, than
    Northwest's account suggests.          A VE partner's notes from the first
    meeting   between      VE   and   American   indicate   that    American    was
    interested in a partial acquisition from the very start:               "AA would
    be   interested   in    the   entire    company   but   there    are    certain
    operations that are particularly important . . .                They would be
    willing to divest some operations."          VE's investigation could not
    have "rested largely" on Continental's strong Houston presence, for
    when this question was brought up in the first meeting, VE noted
    that "AA could sell the Houston hub."             Thus, sometime after the
    meeting a VE partner sent a memo to American explaining that he had
    "spoke[n] at some length" with American's economist and asked that
    the market share data be rerun on the assumption that American
    would not acquire Continental's Houston hub.            While Northwest now
    asserts that VE's advice was based largely on the Houston hub, a VE
    partner at the time stated in yet another memo that even when
    Houston is removed from consideration, "substantial problems are
    created by Continental's other hubs--particularly New York City,
    Chicago, Cleveland, and Denver," as well as by the "substantial
    overlaps between Continental and American on flights to Mexico."
    Northwest's contention that Project Armadillo involved the single
    51
    question of a complete merger and required study of only a few
    markets is simply belied by the record.
    Similarly, it does not appear that market definition and the
    Justice Department's opposition to the merger were as "obvious" as
    Northwest now asserts.   Northwest argues that market definition
    cannot be a common issue between this matter and the present case
    because unlike in the present case, where market definition will be
    hotly disputed, the Department of Justice merger guidelines left
    little room for discussion.   A VE lawyer's notes from the first
    Project Armadillo meeting, however, disclose a different picture:
    [American is] reluctant to take positions in connection
    with a Continental merger that might be inconsistent with
    the positions they are taking elsewhere. This issue came
    up in connection with the discussions of markets.
    Apparently they have developed a variety of different
    views about what are relevant markets. (It appears to me
    that maybe their argument is there are no relevant
    markets).    Evidently the material that they will be
    sending us discusses relevant markets, discusses the
    "city pair" analysis and competition among hubs. . . .
    Apparently they have taken the position that hubs are not
    markets . . . .
    In addition, Northwest contends that the Department of Justice's
    merger guidelines made the answer obvious.       This is not the
    position that VE took during the representation, however.        Upon
    receiving a memo prepared by American setting out the difficulties
    to merger under the city-pair analysis, a VE partner responded that
    the memo was "only the beginning of the analysis in my view."     The
    VE lawyer then went on to suggest that American might be able to
    acquire Continental even though the merger might "violate" the
    guidelines.
    52
    We are forced to the conclusion that the question of market
    definition in Project Armadillo was more complex than Northwest now
    asserts.     VE's representation of American necessarily required a
    detailed evaluation of American's operations in the various markets
    that might be deemed relevant.             The instant case will involve
    similar issues.
    VE was also privy to American's views of the relevant air
    transportation markets, a related matter that will also be at issue
    in   the   present    case.      American    provided   VE   with   materials
    reflecting     AA's    position     on      antitrust   issues      in   prior
    merger/acquisition      cases.      Included    in   these   materials    were
    confidential "white papers" filed by American with the Justice
    Department.
    In support of its claim that markets other than the national
    market are relevant in the present case, Northwest's complaint
    asserts that American "has repeatedly urged that O & D markets and
    regional airline passenger markets are relevant economic markets."
    Three of the examples cited by Northwest in support of this
    allegation appear to be taken from public testimony.           The fourth is
    different:    "AA argued to the Department of Justice in 1989 that
    city pair markets to and from O'Hare Airport constitute relevant
    markets." Northwest does not deny that this statement is contained
    in the materials obtained by VE from American during Project
    Armadillo.     Nor does Northwest claim that this statement is a
    matter of public knowledge.          Rather, Northwest states that it
    simply copied Continental's complaint in drafting its own.               Since
    53
    Northwest's complaint did not involve any independent research by
    VE, the argument seems to run, the allegation cannot possibly be
    based on confidential information supplied by American.        We would
    first point out that Northwest's explanation remains plausible only
    so long as the complaint remains the sole document involved in the
    case.     Northwest will eventually have to address the issues,
    including American's alleged views on the relevant market, on its
    own.    More importantly, the answer given by Northwest is precisely
    one the substantial relationship test forbids.        Once a substantial
    relationship has been established, former counsel is precluded from
    attempting to prove that he did not receive confidences.             See,
    e.g., 
    Corrugated, 659 F.2d at 1347
    .       Northwest's response here--
    that VE might have obtained the information, but did not use it--is
    plainly barred by our precedents.
    We appreciate Northwest's concern that an overly broad reading
    of "subject matter" can leave antitrust counselors with one client
    per industry--a result with little redemptive value.          The nexus
    here is far more than case one and case two both presenting claims
    of attempted monopolization.       Northwest contends that cases like
    Laker Airways Ltd. v. Pan American World Airways, 
    103 F.R.D. 22
    (D.D.C 1984), preclude us from disqualifying VE.         But American's
    showing in this case goes far beyond the same field, same party
    "points of contact" found insufficient in that case.         See 
    id. at 40.
        Rather,   American   has   succeeded   in   "delineat[ing]   with
    specificity the subject matters, issues and causes of action"
    54
    common to prior and present representations in the manner demanded
    by our precedents. 
    Duncan, 646 F.2d at 1029
    .
    VI.
    We   hold   that   VE's   prior    representations   of   American   in
    substantially related matters require the disqualification of VE in
    this case.   We therefore issue a writ of mandamus directing the
    district court to vacate its order denying American's motion and
    enter an order disqualifying VE from representing Northwest.
