    OPINION
    This appeal involves the imputed disqualification of a Nashville law firm from
    continuing to represent a client with interests adverse to those of two former clients
    of one of the law firm’s lawyers. Soon after discovering that their former lawyer
    had joined the law firm representing their adversaries, the former clients filed a
    motion in the Circuit Court for Robertson County seeking to disqualify their
    adversaries’ law firm.     The law firm conceded that the lawyer was personally
    disqualified but opposed disqualifying the entire firm by asserting that it had
    instituted a screening arrangement intended to shield the disqualified lawyer and his
    secretary from the rest of the firm. The trial court declined to disqualify the law firm
    but permitted the former clients to pursue an interlocutory appeal.           We have
    determined that a screening arrangement will not prevent the disqualification of the
    law firm in this case. The disqualified lawyer had at one time served as his former
    clients’ primary lawyer in the very lawsuit before the trial court and, therefore, had
    become heavily involved with the facts of the case and had directly received
    confidential information from his former clients. Accordingly, we reverse the order
    denying the motion to disqualify and remand the case with directions that the trial
    court enter an order disqualifying the plaintiff’s law firm.
    I.
    In the late 1960s, Maclin P. Davis, Jr., then a partner in the Nashville law firm
    of Waller, Lansden, Dortch & Davis, represented C. Roger Blackwood in a divorce
    proceeding. Thereafter, Mr. Davis represented Mr. Blackwood in other matters.
    After Mr. Blackwood married Nancy Dods Blackwood in 1973, Mr. Davis
    represented Ms. Blackwood as well.1 In 1988, Mr. Davis joined the Nashville office
    of Baker, Donelson, Bearman & Caldwell, a large law firm with offices in six cities in
    Tennessee. 2 As far as this record shows, Mr. Davis continued to represent the
    Blackwoods in various matters following his lateral move between firms.
    Page 3
    The Blackwoods own a farm in Robertson County that adjoins property
    owned by John M. and Edward Clinard. For many years, the Clinards leased their
    property to various companies that quarried limestone on the site. Two disputes
    arose between the neighbors after the Blackwoods began building a new home on
    their farm. First, Mr. Blackwood and John Clinard disagreed about the location of
    their boundary line.3 Second, the Blackwoods asserted that blasting at the quarry
    had damaged their new house and stable. According to Mr. Blackwood, American
    Limestone Company, Inc. (“American Limestone”) moderated the blasting and
    performed some clearing and excavation work for the Blackwoods after he
    complained about the blasting. However, the Blackwoods later asserted that the
    blasting at the quarry caused extensive damage to their house.
    In February 1996, Mr. Blackwood repaired portions of the fence along Pepper
    Branch Creek that had sparked his earlier disagreement with John Clinard over the
    location of the boundary line. Two months later, the Clinards filed a declaratory
    judgment action against Mr. Blackwood in the Chancery Court for Robertson
    County seeking to establish the disputed boundary line. Mr. Blackwood retained
    Mr. Davis to represent him in the lawsuit.
    On May 16, 1996, Mr. Davis formally entered an appearance in the case on
    behalf of Mr. Blackwood. Later, on June 24, 1996, Mr. Davis filed an answer and
    counterclaim against the Clinards asserting that the fence was the proper boundary
    line and requesting that the Clinards be enjoined from removing or damaging the
    fence. Mr. Blackwood and Mr. Davis also discussed filing a counterclaim and
    third-party claim against the Clinards and American Limestone for blasting damage
    to their property. However, Mr. Davis eventually informed Mr. Blackwood that he
    could not file a claim against American Limestone because the Baker, Donelson firm
    represented American Limestone in an unrelated environmental matter and because
    American Limestone had declined to permit Mr. Davis to represent interests adverse
    to the company’s. Accordingly, on August 14, 1996, Mr. Davis withdrew as Mr.
    Page 4
    Blackwood’s lawyer and was replaced by Winston S. Evans.
    On September 30, 1996, Mr. Evans filed an amended counterclaim and
    third-party claim on behalf of the Blackwoods against the Clinards and American
    Limestone.    In this pleading, the Blackwoods sought damages from both the
    Clinards and American Limestone for negligent blasting, dumping a large amount of
    contaminated fill material on their farm, and polluting the air with dust from the
    quarry operations. 4 On October 29, 1996, Ames Davis and Waller, Lansden, Dortch
    & Davis entered an appearance on behalf of American Limestone. Approximately
    one month later, Ames Davis and Waller, Lansden, Dortch & Davis replaced the
    lawyer who had represented the Clinards from the outset of the litigation.
    In June 1997, Mr. Davis left the Baker, Donelson firm and returned to Waller,
    Lansden, Dortch & Davis as a non-equity member of the firm. By that time, the
    Waller firm had grown to approximately one hundred lawyers. Upon Mr. Davis’s
    return, the Waller firm implemented its “Conflict of Interest Screening Procedures”
    to prevent Mr. Davis and his secretary from communicating information concerning
    the Blackwoods’ case to the other lawyers and staff of Waller, Lansden, Dortch &
    Davis. 5
    On August 12, 1997, soon after discovering that Mr. Davis had returned to the
    Waller firm, the Blackwoods’ lawyer mailed a letter to Ames Davis stating that the
    Blackwoods did not assent to the Waller firm’s representation of either the Clinards
    or American Limestone and requesting the Waller firm to withdraw from the pending
    lawsuit. Thereafter, on September 22, 1997, the Blackwoods filed a motion in the
    Circuit Court for Robertson County 6 seeking to disqualify Waller, Lansden, Dortch
    & Davis from continuing to represent the Clinards and American Limestone. The
    Waller firm opposed the motion. The trial court considered the motion based on
    affidavits without conducting an evidentiary hearing. On December 16, 1997, the
    trial court declined to disqualify the Waller firm but authorized the Blackwoods to
    Page 5
    seek an interlocutory appeal.        On January 14, 1998, this court granted the
    Blackwoods’ Tenn. R. App. P. 9 application.
    II.
    The practice of law has changed dramatically during the last half of the
    twentieth century. Greater numbers of lawyers practice in firms rather than as sole
    practitioners or in small associations. 7 The number and size of these law firms have
    grown at an accelerating pace, 8 and much of this growth has been accomplished
    through mergers and the lateral hiring of experienced lawyers. 9 In this environment,
    the generation of revenue and the maximization of profit have become important, if
    not primary, drivers of the law firm’s culture. 10
    At the same time that the structure and size of firms have been changing, so
    have the career goals and attitudes of lawyers themselves. As late as twenty years
    ago, it was not uncommon for lawyers to spend their entire career with the law firm
    that hired them right out of law school. Today, there is increased mobility among
    lawyers, and it is not uncommon for associates and even partners to change firms
    several times during their career because of mergers or firm restructuring or because
    they desire to increase their personal income by creating new firms. 11 It is also
    becoming common for law firms to hire temporary lawyers to work a particular
    piece of business with no expectation of continued employment once the business is
    completed.
    The changes in the legal profession have also been accompanied by changes
    in the relationships between law firms and their clients. In today’s competitive,
    cost-conscious environment, clients wield more power than they once did. Clients
    are now more conscious of the cost of legal services. Rather than remaining with a
    single lawyer or law firm as they once did, 12 clients today will frequently shop around
    for legal services or will look to in-house attorneys to provide these services.
    Because of the increased complexity of the legal matters facing clients and the
    growing specialization among lawyers, it is also quite common for clients to be
    Page 6
    represented by more than one lawyer or law firm at any given time.
    These changes in the legal landscape, whether they be lamented or welcomed,
    have had a tendency to generate more conflict of interest problems than ever before.
    13
    These problems have placed a strain on the ethics rules governing the conduct of
    lawyers. The bench and the bar have realized that the traditional rules must be
    adapted to provide practical solutions for the problems currently facing lawyers and
    clients. The profession is now engaged in the process of formulating functional
    rules that give proper weight to the differing, and sometimes competing, interests of
    all parties concerned. Thus, the traditional core professional values of client loyalty,
    the preservation of a client’s confidences and secrets, 14 and the avoidance of the
    appearance of professional impropriety 15 are being re-examined in light of
    prospective clients’ interest in retaining a lawyer of their choice and the legitimate
    prerogative of lawyers to enhance their ability to earn a livelihood in their chosen
    profession. 16 Agreement concerning the proper way to balance these potentially
    competing interests has proven to be elusive, and, even today, the legal profession
    has yet to reach a consensus on many important issues. 17
    Among the most intransigent ethics issues currently confronting the profession
    involves the use of screening arrangements to avoid the imputed disqualification of
    an entire law firm because of a single member’s conflict of interest with a former
    client. For the past twenty-five years, lawyers and judges have debated whether and
    in what circumstances screening arrangements should be allowed.              This case
    requires us to revisit this issue at a time when the organized bar in Tennessee is
    exerting increasing pressure on the courts to permit the use of screening
    arrangements to avoid the seemingly harsh effects of imputed disqualification. 18
    The propriety of using screening arrangements has precipitated a pointed
    debate among practicing lawyers, judges, and academicians. Those favoring the use
    of screening arrangements insist that they are an appropriate way to protect clients’
    free access to lawyers of their choice and to facilitate lawyer mobility without
    Page 7
    sacrificing client confidentiality. 19 Those opposing the use of screening arrangements
    insist that the profession’s ancient obligation to protect a former client’s confidences
    should not be diluted by lawyers’ pragmatic business interests. 20 Even the most
    cursory examination of the literature on the subject reveals that the debate over the
    use of screening arrangements by lawyers in private practice is far from settled and
    that the prospects of an early consensus are guarded.
    The Tennessee Supreme Court has yet to provide an authoritative
    interpretation of Tenn. S. Ct. R. 8, DR 5-105(D), and the Tennessee Bar Association
    has yet to present its proposed rules to the Court. Thus, Tennessee’s bench and
    bar must await the Court’s definitive guidance concerning the viability of screening
    arrangements by lawyers in private law firms. Based on the facts of this case, we
    have determined that the screening arrangement employed by Waller, Lansden,
    Dortch & Davis for Mr. Davis and his secretary cannot prevent the disqualification
    of the entire firm. Mr. Davis became deeply involved in the facts of this case when
    he served as the Blackwoods’ primary lawyer. Accordingly, it is virtually certain that
    Mr. Davis obtained significant confidential information from the Blackwoods while
    he was representing them and that this information could, if divulged either
    purposefully or accidentally, cause material adverse effects on the Blackwoods in the
    present litigation.
    III.
    We recognize at the outset that the most authoritative sources for the
    principles needed to decide this case are the rules and opinions of the Tennessee
    Supreme Court. The Court has the exclusive power to regulate the conduct of
    lawyers in Tennessee. See In re Petition of Burson, 
    909 S.W.2d 768
    , 773 (Tenn.
    1995); Smith County Educ. Ass’n v. Anderson, 
    676 S.W.2d 328
    , 333 (Tenn. 1984);
    see also Restatement (Third) of the Law Governing Lawyers § 1 cmt. c (Proposed
    Final Draft No. 2, 1998). All lawyers, upon admission to the bar, become officers of
    Page 8
    the Court, see Andrews v. Bible, 
    812 S.W.2d 284
    , 291 (Tenn. 1991); Ward v. Alsup,
    
    100 Tenn. 619
    , 739, 
    46 S.W. 573
    , 574 (1898), and thereby become subject to the
    power of the Court to prevent and punish professional misconduct. See Memphis
    & Shelby County Bar Ass’n v. Vick, 
    40 Tenn. App. 206
    , 214, 
    290 S.W.2d 871
    , 875
    (1955).
    Early in our history, the courts fashioned the rules governing both the practice
    of law and the conduct of lawyers from common-law principles and from their own
    understanding of the practice of law and the role of lawyers in litigation. In the early
    part of this century, however, the organized bar, motivated to some degree by
    self-interest 21 began to play a more active role in regulating the conduct of lawyers by
    adopting ethics codes for the profession. 22 These codes, for the most part, reflected
    the rules and principles that had been fashioned by the courts over the years. 23
    Accordingly, the rules in the organized bar’s early ethics codes virtually mirrored the
    judicial decisions regarding lawyer conduct.
    As time went by, the courts began to cite the organized bar’s ethics codes as
    authority for their decisions regulating the conduct of lawyers. In time, the judiciary’
    s reliance on ethics codes thoroughly blurred the line between the use of ethics
    codes for disciplinary purposes and the use of ethics codes to regulate lawyers’
    conduct during litigation.24 Eventually, some courts adopted a restrained approach
    leaving the enforcement of ethics codes to the bar’s existing disciplinary machinery.
    See, e.g., Armstrong v. McAlpin, 
    625 F.2d 433
    , 445-46 (2d Cir. 1980), vacated on
    other grounds, 
    449 U.S. 1106
     (1981). Other courts have rejected this “hands off”
    approach in favor of addressing directly unethical conduct occurring in connection
    with pending litigation. See, e.g., In re American Airlines, 
    972 F.2d 605
    , 611 (5th
    Cir. 1992). Tennessee’s courts have not hesitated to rely on ethics code provisions
    to protect the integrity of the judicial process or the rights of litigants when an ethical
    violation taints or threatens to taint a trial’s fairness. See Woodside v. Woodside,
    No. 01A01-9503-PB-00121, 
    1995 WL 623077
    , at *8 (Tenn. Ct. App. Oct. 25, 1995)
    (Koch, J., concurring), perm. app. denied concurring in results only (Tenn. Jan. 8,
    Page 9
    1996) (describing the judicial resolution of five issues using the Code of Professional
    Responsibility).
    Ethics codes were never intended to supplant the court-created principles of
    professional conduct or to prevent the courts from continuing to refine and apply
    these principles. For the good of the profession, the courts have a continuing
    obligation to safeguard the attorney-client relationship and to maintain the public’s
    confidence in the integrity of the legal system. See Panduit Corp. v. All States
    Plastic Mfg. Co., 
    744 F. 2d 1564
    , 1576 (Fed. Cir. 1984); Freeman v. Chicago
    Musical Instrument Co., 
    689 F.2d 715
    , 721 (7th Cir. 1982); In re Estate of Waters,
    
    647 A.2d 1091
    , 1098 (Del. 1994); Ciaffone v. Eighth Judicial Dist. Court, 
    945 P.2d 950
    , 953 (Nev. 1997); Kala v. Aluminum Smelting & Refining Co., 
    688 N.E.2d 258
    , 262 (Ohio 1998).
    In 1908, the American Bar Association adopted its first ethics code known as
    the Canons of Professional Ethics. The Tennessee Bar Association adopted the first
    thirty-two of these canons in 1909, 25 but the Tennessee Supreme Court did not place
    its imprimatur on these canons until 1938. 26      Even since 1938, the Tennessee
    Supreme Court has patterned its rules governing the conduct of lawyers after the
    ethics codes drafted by the American Bar Association. 27
    The Code of Professional Responsibility, as adopted by the Tennessee
    Supreme Court, has the force and effect of law. See Gracey v. Maddin, 
    769 S.W.2d 497
    , 504 (Tenn. Ct. App. 1989) (Koch, J., dissenting); King v. King, No.
    89-46-11, 
    1989 WL 122981
    , at *11 (Tenn. Ct. App. Oct. 18, 1989) (Koch, J.,
    concurring) (No Tenn. R. App. P. 11 application filed). 28 However, the Code of
    Professional Responsibility is itself divided into Canons, Ethical Considerations, and
    Disciplinary Rules, and each of these divisions has different authoritative weight.
    The Canons are “statements of axiomatic norms” that “embody the general concepts
    from which the Ethical Considerations and the Disciplinary Rules are derived.” The
    Ethical Considerations are “aspirational in character and represent objectives toward
    Page 10
    which every member of the profession should strive.” Finally, the Disciplinary Rules
    are “mandatory in character” and state “the minimum level of conduct below which
    no lawyer can fall without being subject to disciplinary action.” See Tenn. S. Ct. R.
    8, Preamble.
    The Tennessee Supreme Court is the chief arbiter of the meaning of its own
    rules. See In re Gant, 
    937 S.W.2d 842
    , 846 (Tenn. 1996). However, in 1981, the
    Court reluctantly empowered 29 the Board of Professional Responsibility and its
    disciplinary counsel to issue formal and informal advisory ethics opinions construing
    the Court’s own ethics rules. See Tenn. S. Ct. R. 9, § 26, West Publishing Co.,
    Tennessee Decisions 609-614 S.W.2d at cxxxv. The formal ethics opinions, which
    only the Board may issue, “constitute a body of principles and objectives upon
    which members of the bar can rely for guidance in many specific situations.” Tenn.
    S. Ct. R. 9, § 26.4(a). 30 However, even though formal ethics opinions are binding on
    the Board and the person requesting the opinion, 31 they are not binding on the courts.
    See In re Youngblood, 
    895 S.W.2d 322
    , 325 (Tenn. 1995); State v. Jones, 726
    S.W.2d at 519-20. Nonetheless, formal ethics opinions can provide guidance to the
    courts because they reflect the legal profession’s considered opinions regarding the
    appropriate standards of practice. See King v. King, 
    1989 WL 122981
    , at *12
    (Koch, J., concurring).
    IV.
    The parties have presented starkly different portrayals of the legal profession’
    s current attitude regarding screening arrangements. On one hand, Waller, Lansden,
    Dortch & Davis asserts that screening arrangements in the private sector have
    become generally accepted and are currently being widely used; while the
    Blackwoods assert that screening arrangements have fallen into disfavor.          Both
    parties are, at least in part, correct. There is, however, currently no consensus
    among the members of the legal profession concerning the necessary ingredients of
    screening arrangements or the circumstances in which a screening arrangement may
    Page 11
    be used to avoid the consequences of the imputed disqualification doctrine.
    A.
    The Conflict of Interest Rules
    The fiduciary relationship between a lawyer and a client requires the lawyer to
    exercise the utmost good faith to protect the client’s interests. See Alexander v.
    Inman, 
    974 S.W.2d 689
    , 693-94 (Tenn. 1998); Fitch v. Midland Bank & Trust Co.,
    
    737 S.W.2d 785
    , 789 (Tenn. Ct. App. 1987). Lawyers must preserve their client’s
    confidences and secrets, exercise independent judgment on their client’s behalf, and
    represent their client zealously within the bounds of the law. See Tenn. S. Ct. R. 8,
    Canons 4, 5 & 7; Dyer v. Farley, No. 01A01-9506-CH-00229, 
    1995 WL 638542
    , at
    *5-6 (Tenn. Ct. App. Nov. 17, 1995) (No Tenn. R. App. P. 11 application filed).
    They must also avoid serving two clients whose interests are adverse to each other.
    See State v. Locust, 
    914 S.W.2d 554
    , 557 (Tenn. Crim. App. 1995).
    The prohibition against serving two masters is enforced using conflict of
    interest rules developed by the courts long before the organized bar began adopting
    ethics codes. See Restatement (Third) of the Law Governing Lawyers § 1 cmt. b, at
    3 (Proposed Final Draft No. 2 1998). Many of the conflict of interest rules have
    now been incorporated into the organized bar’s ethics codes. See Henriksen v.
    Great Am. Sav. & Loan, 14 Cal. Rptr. 2d at 186; Hamilton & Coan, supra note 20,
    at 66; Restatement (Third) of the Law Governing Lawyers, Forward, at xxiii-xxiv
    (Proposed Final Draft No. 1, 1996).
    A conflict of interest arises whenever a lawyer is placed in a position of
    divided loyalties - a circumstance in which a lawyer’s regard for the duty owed to
    one client tends to lead to disregard of the duty owed to another client. See State v.
    Tate, 925 S.W.2d at 552. To avoid conflicts of interest, lawyers are prohibited from
    undertaking to represent a client whose interests are adverse to those of one of the
    lawyer’s other clients. See State v. Phillips, 
    672 S.W.2d 427
    , 430-31 (Tenn. Crim.
    Page 
    12 App. 1984
    ); Autry v. State, 1 Tenn. Crim. 95, 98, 
    430 S.W.2d 808
    , 809 (1967).
    These conflict of interest prohibitions continue to govern a lawyer’s conduct
    after he or she is no longer representing a client. See Mills v. Crane, No. 66, 
    1987 WL 9165
    , at *4 (Tenn. Ct. App. Apr. 10, 1987), perm. app. denied (Tenn. July 27,
    1987); American Nat’l Bank v. Bradford, 
    28 Tenn. App. 239
    , 262, 
    188 S.W.2d 971
    , 981 (1945); Tenn. S. Ct. R. 8, EC 4-6. 32 In fact, they continue after the death of
    a client or former client. See Restatement (Third) of the Law Governing Lawyers §
    112 cmt. 2, at 280 (Proposed Final Draft No. 1 1996). Therefore, a lawyer may not
    represent interests materially adverse to those of a former client if the subject matter
    of the new representation is substantially related to the subject matter of the previous
    representation.   See State v. Hoggett, No. 01C01-9003-CR-00073, 
    1990 WL 172632
    , at *2 (Tenn. Crim. App. Nov. 9, 1990) (No Tenn. R. App. P. 11 application
    filed); Mills v. Crane, 
    1987 WL 9165
    , at *5.
    The application of the conflict of interest prohibitions to individual lawyers is
    relatively straightforward. A lawyer must not simultaneously represent two or more
    persons who have adverse interests in the same subject matter. See Tenn. S. Ct. R.
    8, DR 5-105(A), EC 5-15; State v. Tate, 925 S.W.2d at 552. Likewise, a lawyer
    must not switch sides during an ongoing dispute. See Henriksen v. Great Am. Sav.
    & Loan, 14 Cal. Rptr. 2d at 187; Straub Clinic & Hosp. v. Kochi, 
    917 P.2d 1284
    ,
    1290 (Haw. 1996); State ex rel. Freezer Servs., Inc. v. Mullen, 
    458 N.W.2d 245
    , 249
    (Neb. 1990); Kala v. Aluminum Smelting & Refining Co., 688 N.E.2d at 266.
    Finally, a lawyer cannot undertake to represent a client with interests adverse to
    those of a former client. See Mills v. Crane, 
    1987 WL 9165
    , at *4.
    B.
    The Imputed Disqualification Doctrine
    The growth in the number and size of law firms and the increased career
    mobility of lawyers have created new dimensions to conflict of interest problems.
    Page 13
    In addition to the primary disqualification rules applicable to individual lawyers,
    secondary or imputed disqualification rules became necessary to deal with lawyers
    practicing in a firm setting. Developing and refining the principles for imputed
    disqualification has not been an easy task.
    Simply stated, the doctrine of imputed disqualification provides that if the
    conflict of interest rules require the disqualification of an individual lawyer, then all
    that lawyer’s professional colleagues are likewise disqualified. See Laskey Bros. of
    W. Va., Inc. v. Warner Bros. Pictures, Inc., 
    224 F.2d 824
    , 826 (2d Cir. 1955);
    Bateman, supra note 8, at 254; Hamilton & Coan, supra note 20, at 73; Lee A.
    Pizzimenti, Screen Verite: Do Rules About Ethical Screens Reflect the Truth About
    Real-Life Law Firm Practice?, 
    52 U. Miami L. Rev. 305
    , 310 (1997).                  This
    principle is based on common sense assumptions concerning the way lawyers work
    in a firm setting, including the personal and financial relationships among members of
    a law firm and the motivations for firm members to share information and to support
    each other’s efforts. 33 It is also premised on the common-law rule that partners are
    deemed to be agents of one another. 34
    The essential component of the imputed disqualification doctrine is the
    presumption that lawyers associated in a law practice, as agents of one another,
    know what the other lawyers in the firm know. See Penegar, supra note 9, at 848.
    Thus, it is presumed that information regarding a client that has been imparted to one
    member of a law firm has been shared with, and is known by, the other members of
    the firm.    See State v. Claybrook, 
    1992 WL 17546
    , at *8.            When a client’s
    confidence and secrets are involved, this presumption is commonly referred to as
    the presumption of shared confidences.
    By 1969, the doctrine of imputed disqualification had become so widely
    accepted that the American Bar Association included it in the Code of Professional
    Responsibility. 35   See Model Code of Professional Responsibility DR 5-105(D)
    (1969). The American Bar Association broadened the 1969 version of DR 5-105(D)
    in 1974 to require imputed disqualification of affiliated lawyers whenever an
    Page 14
    individual lawyer becomes disqualified under any disciplinary rule. See Model Code
    of Professional Responsibility DR 5-105 (1974). 36 The 1974 version of DR 5-105(D)
    is currently part of Tennessee’s Code of Professional Responsibility. See Tenn. S.
    Ct. R. 8, DR 5-105(D). 37
    The imputed disqualification doctrine in both the 1969 and 1974 versions of
    DR 5-105(D) did not directly address conflicts of interest arising when a personally
    disqualified lawyer joins a firm that would not otherwise be disqualified. However,
    when this issue reached the courts, most state and federal courts invoked the
    imputed disqualification doctrine, citing DR 5-105(A) & (D), DR 4-101 (the
    preservation of a client’s confidences and secrets), and Canon 9 (the avoidance of
    an appearance of impropriety). These decisions were not well received in some
    quarters of the legal profession who believed that the 1974 version of DR 5-105(D)
    was much too broad and that it gave too much leeway to the courts. 38 Accordingly,
    these lawyers set out to find a remedy for their predicament and eventually decided
    that internal screening arrangements similar to those used by financial institutions to
    prevent internal communication between departments could be adapted for use by
    the legal profession. 39 In theory, these internal screening arrangements would insulate
    the rest of the firm from the personally conflicted lawyer and would thereby provide
    evidence sufficient to rebut the presumption of shared confidences.
    One year after the 1974 amendment to DR 5-105(D), the American Bar
    Association, following intensive lobbying by Washington and New York law firms, 40
    modified its traditional stance regarding imputed disqualification.         Citing the
    government’s need for competent lawyers, the ABA’s Committee on Ethics and
    Professional Responsibility approved the use of screening arrangements for former
    government lawyers even though the Code of Professional Responsibility did not
    mention the use of screening arrangements. See ABA Committee on Ethics and
    Professional Responsibility, Formal Op. 342 (1975). Two years later, the United
    States Court of Claims followed Formal Op. 342, see Kesselhaut v. United States,
    
    555 F.2d 791
    , 793 (Ct. Cl. 1977), and within several years, the federal courts began
    Page 15
    to view Formal Op. 342 as an amendment to the Code of Professional
    Responsibility. See Fields, supra note 11, at 243.
    Even though the reasoning of Formal Op. 342 and Kesselhaut v. United
    States has been questioned, 41 the approval of the use of screening arrangements for
    former government lawyers emboldened the proponents of screening arrangements,
    and they continued to press forward on two fronts to gain approval of screening
    arrangements for lawyers in private practice. First, they continued their efforts to
    persuade the courts that evidence of the prompt use of screening arrangements
    should rebut the presumption of shared confidences. Second, they set out to amend
    the ethics rules to include provisions explicitly approving the use of screening
    arrangements in the private sector. As matters currently stand, the efforts to amend
    the ethics codes have borne more fruit than the efforts to convince courts that
    screening arrangements are the panacea for imputed disqualification problems.
    C.
    Changes in the Ethics Codes
    The first modern effort to rewrite the profession’s ethics codes began in 1977
    when the American Bar Association created the Commission on the Evaluation of
    Professional Standards (commonly known as the “Kutak Commission”) and ended
    in 1983 with the adoption of the Model Rules of Professional Conduct. The Kutak
    Commission eventually concluded that nothing less than a comprehensive
    reformulation of the ethical standards of the legal profession was called for.
    Between 1979 and 1982, the Kutak Commission produced four major drafts of new
    ethics rules that entirely reworked the structure and substance of the Code of
    Professional Responsibility. 42   Rather than reflecting consensus, these drafts
    prompted controversy and dissent. In fact, two other professional organizations
    produced competing ethics codes. 43 The range of opinions regarding the appropriate
    standards for the profession reflected the ethical pluralism among the members of
    the bar. 44
    Page 16
    Two matters taken up in the process of adopting the Model Rules of
    Professional Conduct are relevant to this appeal. First, both the Kutak Commission
    and the House of Delegates decided that Canon 9's “appearance of impropriety”
    standard that had figured so prominently in the development of the imputed
    disqualification rule was too indefinite. 45    Accordingly, the Model Rules of
    Professional Conduct explicitly reject the “appearance of impropriety” standard as “
    subjective” and “question-begging.” See ABA Model Rules of Professional Conduct
    Rule 1.10 cmt. (Lawyers Moving Between Firms; third paragraph) (1983).
    The second issue germane to this case involves the use of screening
    arrangements by lawyers in private practice to avoid the consequences of the
    imputed disqualification doctrine. The Kutak Commission’s initial discussion draft
    issued in January 1980 did not explicitly address the imputed disqualification
    doctrine or the use of screening arrangements; however, the draft considered at the
    American Bar Association’s February 1983 meeting did. By this time, proposed
    Rule 1.10 had been rewritten to address imputed disqualification directly. 46 The
    Commission added Comment No. 11 to Rule 1.10 containing factors for the courts
    to consider in determining whether imputed disqualification was required in a
    particular case. One of the factors was “the nature and probable effectiveness of
    screening measures.”47 Thus, this version of the proposed Code, at least implicitly,
    allowed lawyers in private practice to use screening arrangements. 48
    Proposed Rule 1.10 and its comments were rewritten between the House of
    Delegates’ February 1983 and May 1983 meetings. The Commission replaced the
    original Section 1.10(b) with a new Section 1.10(b) dealing with lawyers becoming
    associated with a firm and with a new Section 1.10(c) dealing with lawyers
    terminating their association with a firm. 49    The Commission also deleted the
    comment containing the factors for determining whether to invoke the imputed
    disqualification rule. 50
    Page 17
    The Model Rules of Professional Conduct adopted by the American Bar
    Association’s House of Delegates in August 1983 differed significantly from the
    original Kutak Commission proposals. Ultimately, both the Kutak Commission and
    the American Bar Association rejected the use of screening mechanisms for private
    lawyers but approved their use for former government lawyers, just as Formal Op.
    342 had done nine years earlier.51 However, the comments to the 1983 version of
    Rule 1.10 imply that mandatory imputed disqualification is not the answer in every
    case and that the courts should decide these questions on a case-by-case basis and
    that the presumption of shared confidences should be tempered by the personally
    conflicted lawyer’s actual role in the present and former firm and his or her actual
    knowledge of privileged information. 52
    The American Bar Association’s reconsideration of professional ethics did
    not end with the adoption of the Model Rules of Professional Conduct. These rules
    have been amended twenty-eight times since their adoption in 1983. See Ann. Model
    Rules of Professional Conduct, supra note 45, at vii. Amendments adopted in 1989
    moved several provisions in original Rule 1.10(b) and the corresponding comments
    to Rule 1.09 and broadened Rule 1.9(c). See Ann. Model Rules of Professional
    Conduct, supra note 45, at 579. In their present form, Rules 1.9 and 1.10 (and Rule
    1.11 dealing with former government lawyers) depart significantly from the form and
    substance of the Code of Professional Responsibility. They tailor the imputed
    disqualification rules to particular conflicts of interest situations that require firm
    disqualification because of a specific danger of conflicting representation by other
    members of the firm. See Wolfram, supra note 33, § 7.6.2, at 395. They also
    envision that a lawyer joining a firm should be deemed to carry his or her actual
    knowledge only and that the new firm’s status should be decided accordingly. See
    Hazard & Hodes, supra note 33, § 1.1:207, at 335-36.
    The efforts to amend the ethics rules to include explicit approval for screening
    arrangements proved to be more successful in the context of the drafting and
    approval of the American Law Institute’s Restatement (Third) of the Law Governing
    Page 18
    Lawyers. Section 204(2) of the Restatement, approved on May 12, 1998, permits
    private law firms to use screening arrangements to avoid the application of the
    imputed disqualification doctrine. Following the final approval of the Restatement,
    the American Bar Association announced the creation of the Commission on the
    Evaluation of the Rules of Professional Conduct (popularly known as “Ethics
    2000") to evaluate the Model Rules of Professional Conduct in light of the variations
    in the rules as adopted at the state level and the provisions in the Restatement. 53 The
    Ethics 2000 Commission has already circulated proposed revisions to the comments
    associated with Rule 1.10 regarding the use of screening arrangements for
    non-lawyer support personnel and lawyers. These proposals would permit the use
    of screening arrangements for non-lawyer support personnel who change jobs and
    for new lawyers who worked at an opposing law firm as law clerks but would not
    permit the use of screening arrangements to cure conflicts of interest created when a
    personally disqualified lawyer changes firms. See Current Reports, Laws. Man. on
    Prof Cond. (ABA/BNA) 259 (June 9, 1999).
    Even as the American Bar Association and the American Law Institute
    considered the propriety of screening arrangements for lawyers in private practice,
    several states amended their ethics rules to permit the use of screening arrangements.
    To date, six jurisdictions have amended their ethics rules to approve the use of
    screening arrangements by private lawyers. 54 One jurisdiction has approved the use
    of screening arrangements by law students and lawyers affiliated with the law school’
    s legal clinic. 55 Another jurisdiction has not specifically approved the use of the
    screening arrangements but has adopted the draft comments to ABA Model Code of
    Professional Conduct Rule 1.10 listing screening arrangements among the factors
    that the court should consider when determining whether to invoke the imputed
    disqualification doctrine. 56
    In three jurisdictions that have not amended their ethics rules, administrative
    disciplinary bodies have issued opinions approving the use of screening
    arrangements.     Like Tennessee Board of Professional Responsibility’s Formal
    Page 19
    Ethics Op. 89-F-118 (Mar. 10, 1989), the Ohio Board of Commissioners on
    Grievances and Discipline has approved the use of screening arrangements by
    members of the private bar.             See Ohio Bd. of Comm’rs on Grievances and
    Discipline       Advisory    Op.    89-013   (May      30,   1989),   
    1989 WL 535018
    (OhioBd.Comm.Griev.Disp.); Hamilton & Coan, supra note 20, at 82-83 n.105.
    Another jurisdiction’s ethics advisory committee has approved the use of screening
    arrangements but only when the former client has approved the former lawyer’s new
    firm’s representation of the adverse party. See S.C. Bar Ethics Adv. Comm. Op.
    92-23 (Oct. 1992), 
    1992 WL 810439
     (S.C.Bar.Eth.Adv.Comm.).
    D.
    The Courts’ Response to the Imputed Disqualification Doctrine and to
    Screening Arrangements
    Most    courts    currently   employ     a   three-step   approach   to   imputed
    disqualification issues. The first step involves determining whether a substantial
    relationship exists between the subject matter of the former representation and the
    subject matter of the subsequent adverse representation. The second step involves
    determining whether the lawyer who has changed firms is personally disqualified
    under the applicable conflict of interest rules. The third step involves determining
    whether the lawyer’s new firm must also be disqualified from representing the party
    with an interest adverse to the interests of the personally conflicted lawyer’s former
    client.
    The “substantial relationship” inquiry is universally accepted as the starting
    point for the disqualification analysis. 57 While it has several formulations, the inquiry
    examines (1) the scope of the former representation, (2) whether it is reasonable to
    infer that confidential information would have been given to a lawyer representing a
    client in such matters, and (3) whether the information is relevant to the issues being
    raised in the litigation pending against the former client. See LaSalle Nat’l Bank v.
    County of Lake, 
    703 F.2d 252
    , 255-56 (7th Cir. 1983). If the court finds that there is
    Page 20
    no substantial relationship between the subject matter of the former and present
    representations, the inquiry ends because there can be no conflict of interest between
    the lawyer and his or her former client or between the former client and the lawyer’s
    new law firm. If, however, the court finds that a substantial relationship exists, then
    the court must determine whether the lawyer should be disqualified.
    There are two bases for disqualifying the lawyer if the court finds a substantial
    relationship between the subject matter of the present and former representations.
    First, the lawyer could be disqualified if he or she has a primary conflict of interest
    resulting from the lawyer’s direct exposure to the former client’s confidential
    information. Second, the lawyer , like the rest of the lawyer’s former firm, could be
    disqualified if he or she has a secondary conflict of interest arising from the
    presumption of shared confidences.
    A majority of courts hold that the presumption of shared confidences with
    regard to the information received by the lawyer’s former firm is irrebuttable once a
    substantial relationship between the present and former representations has been
    established. See Arkansas v. Dean Foods Prods. Corp., 
    605 F. 2d 380
    , 384-85 (8th
    Cir. 1979), overruled on other grounds by In re Multi-Piece Rim Prods. Liab.
    Litigation, 
    612 F.2d 377
    , 378 (8th Cir. 1980); Emle Indus. v. Pantentex, Inc., 
    478 F.2d 562
    , 570-71 (2d Cir. 1973); Koch v. Koch Indus., 
    798 F. Supp. 1525
    , 1536 (D.
    Kan. 1992). 58 Other courts have held that the presumption can be rebutted if the
    lawyer shows that he or she was not privy to any confidential information. This
    approach is not widely accepted and has generally been followed only in cases
    involving associates of large firms who performed minor tasks such as researching
    points of law. See Silver Chrysler Plymouth, Inc. v. Chysler Motors Corp., 
    518 F.2d 751
    , 756-57 (2d Cir. 1975) (differentiating between lawyers who become
    heavily involved in the facts of a particular matter and those who enter briefly on the
    periphery); Ann. Model Rules of Conduct, supra note 45, at 157-59; Bateman,
    supra note 8, at 253.
    Page 21
    Once the party seeking disqualification establishes a prima facie case, the
    burden of proof shifts to the lawyer and the firm whose disqualification is sought to
    demonstrate why they should not be disqualified. See SLC Ltd. v. Bradford Group
    West, Inc., 
    999 F.2d 464
    , 468 (10th Cir. 1993); Norman v. Norman, 
    970 S.W.2d 270
    , 274 (Ark. 1998); Koulisis v. Rivers, 
    730 So. 2d 289
    , 292 (Fla. Dist. Ct. App.
    1999); Heringer v. Haskell, 
    536 N.W.2d 362
    , 365 (N.D. 1995); Hazard & Hodes,
    supra note 33, § 1.10:208, at 338.5. This rebuttal effort should not force either party
    to reveal the former client’s confidential information. See Wolfram, supra note 33, §
    7.6.3, at 399; Fields, supra note 11, at 237. Any doubts regarding the existence of
    an asserted conflict of interest should be resolved in favor of disqualification. See
    Westinghouse Elec. Corp. v. Gulf Oil Corp., 
    588 F.2d 221
    , 225 (7th Cir. 1978);
    Koulisis v. Rivers, 
    730 So. 2d at 292
    ; Angleton v. Estate of Angleton, 
    671 N.E.2d 921
    , 928 (Ind. Ct. App. 1996); Dow Chem. Co. v. Mahlum, 
    970 P.2d 98
    , 123 (Nev.
    1998); Herbert v. Haytaian, 
    678 A.2d 1183
    , 1189 (N.J. Super. Ct. App. Div. 1996);
    Burkes v. Hales, 
    478 N.W.2d 37
    , 41 (Wis. Ct. App. 1991).
    If there is a substantial relationship between the former and present
    representations and if the lawyer who has changed firms is personally disqualified
    from representing the present client because of a conflict of interest regarding the
    former client, then the final step of the analysis is to determine whether the lawyer’s
    new firm should be disqualified by implication. For those courts following the
    traditional view that the presumption of shared confidences is irrebuttable, imputed
    disqualification of the new firm is mandatory.     See ABA Comm. on Ethics and
    Professional Responsibility, Formal Op. 33 (1931); ABA Model Code of
    Professional Responsibility DR 5-105(D); ABA Model Rules of Professional
    Conduct § 1.10(b) (1983); Bateman, supra note 8, at 254, 266 n.105; Fields, supra
    note 11, at 236-37 n. 36.        Other courts, believing that mandatory imputed
    disqualification casts an unnecessarily wide shadow, are reluctant to invoke the
    doctrine to disqualify the new law firm except as a last resort. For these courts, the
    presumption of shared confidences among the lawyer and his or her associates at the
    new firm is rebuttable. See Freeman v. Chicago Musical Instrument Co., 689 F.2d
    Page 22
    715, 722-23 (7th Cir. 1982).
    Courts viewing the presumption of shared confidences as rebuttable must
    balance the former client’s legitimate right to be free from apprehension that its
    confidential information will be revealed with the party’s interest in choosing his or
    her own lawyer and with the former lawyer’s interest in following his or her career
    path to its best advantage. See Barragree v. Tri-County Elec. Co-op, Inc., 
    950 P.2d 1351
    , 1357 (Kan. 1997); Gellman v. Hilal, 
    607 N.Y.S.2d 853
    , 855 (Sup. Ct.
    1994). In this balancing process, the first client’s right to preserve its confidential
    information is entitled to greater weight than the later client’s right to retain counsel
    of its own choosing, see Donohoe v. Consolidated Operating & Prod. Corp., 
    691 F. Supp. 109
    , 118 (N.D. Ill. 1988); State ex rel. FirstTIER Bank, N.A., v. Buckley,
    
    503 N.W.2d 838
    , 842 (Neb. 1993), as well as the employment and staffing interests
    of the incoming lawyer and the new law firm. See Kala v. Aluminum Smelting &
    Refining Corp., 688 N.E.2d at 267 (holding that a law firm may be required to
    subordinate its desire to augment its staff to its duties to its clients).
    Law firms seeking to avoid the effect of the imputed disqualification rule must
    prove their case by clear and effective proof. See Schiessle v. Stephens, 
    717 F.2d 417
    , 420 (7th Cir. 1983); Freeman v. Chicago Musical Instrument Co., 
    689 F.2d at 723
    ; Nelson v. Green Builders, Inc., 
    823 F. Supp. 1439
    , 1448 (E.D. Wis. 1993);
    State v. Tate, 925 S.W.2d at 557-58. As a general matter, law firms have attempted
    to rebut the presumption of shared confidences in two ways.                  In jurisdictions
    governed by a version of the Model Rules of Professional Conduct, firms undertake
    to prove that the moving lawyer did not have a primary conflict of interest resulting
    from his or her direct receipt of confidential information from a former client of the
    former firm. 59 See Trustco Bank of N.Y. v. Melino, 
    625 N.Y.S.2d 803
    , 806-07 (Sup.
    Ct. 1995); Hazard & Hodes, supra note 33, § 1.10:208; Bateman, supra note 8, at
    268. Law firms have also sought to avoid the effects of the imputed disqualification
    rule through the use of screening arrangements. See Schiessle v. Stephens, 
    717 F.2d at 421
    ; Bateman, supra note 8, at 254; Penegar, supra note 9, at 859. Because
    Page 23
    screening arrangements are now generally accepted when a private firm employs a
    former government lawyer, these law firms assert that there is no substantive
    difference between lawyers moving from government to the private sector and
    lawyers moving between private firms. See Manning v. Waring, Cox, James, Sklar
    & Allen, 849 F.2d at 226; Ann. Model Rules of Professional Conduct Rule 1.9,
    supra note 45, at 159.
    The use of screening arrangements for lawyers moving from one private firm
    to another remains highly controversial, see Hamilton & Coan, supra note 20, at 59,
    and has not been approved by a majority of the courts that have been squarely
    presented with the issue. Currently, United States Courts of Appeals for four
    circuits, 60 five United States District Courts, 61 and courts in six states 62 have approved
    the private sector use of screening arrangements. At the same time, United States
    Courts of Appeal in five circuits have declined to approve screening arrangements. 63
    Likewise, United States Court of Appeals in two circuits, 64 eight United States
    District Courts, 65 and courts in ten states 66 have rejected the use of screening

    approve screening arrangements. 67
    V.
    Imputed Disqualification in Tennessee
    Tennessee is one of the few remaining jurisdictions whose ethics rules for the
    legal profession are based on the American Bar Association’s Model Code of
    Professional Responsibility. The Tennessee Supreme Court adopted an amended
    version of this code in 1970. While the Court has amended the code on nine
    occasions to accommodate developments such as IOLTA, legal specialization, and
    lawyer advertising, the form and substance of the code has remained essentially
    unchanged for the past thirty years.
    While the provisions of the Code of Professional Responsibility applicable to
    Page 24
    this case have remained unchanged, the Board of Professional Responsibility’s
    interpretation of them has not. In 1981, broadly construing Tenn. S. Ct. R. 8, DR
    5-105(D), the Board opined that “[w]hen an attorney is barred from representation
    on the ground of knowledge actually or presumably acquired from a former
    representation, then the entire firm is similarly barred.” Tenn. Bd. of Professional
    Responsibility, Formal Op. 81-F-5 (Apr. 17, 1981), 
    1981 WL 165063
     (Tenn.Bd.
    Prof.Resp). Six years later, the Board, citing its earlier opinion, disapproved of the
    use of screening arrangements for paralegals who moved from one opposing firm to
    another. See Tenn. Bd. of Professional Responsibility, Formal Op. 87-F-110 (June
    10, 1987), 
    1987 WL 364064
     (Tenn.Bd.Prof.Resp.). Three months later, the Board
    appeared to apply a more relaxed rule to district attorney generals’ offices. In
    keeping with the accepted recognition of differences between lawyers in public
    service and those in private practice, the Board stated that imputed disqualification
    should be considered on a case-by-case basis when a member of a district attorney
    general’s staff formerly represented a defendant. See Tenn. Bd. of Professional
    Responsibility, Formal Op. 87-F-111 (Sept. 16, 1987), 
    1987 WL 364065
    (Tenn.Bd.Prof.Resp.).
    In 1988, the United States Court of Appeals for the Sixth Circuit held that
    screening arrangements provided private law firms with the same protection from
    imputed disqualification when they hired a lawyer in private practice that it provided
    when they hired a former government lawyer. See Manning v. Waring, Cox, James,
    Sklar & Allen, 849 F.2d at 225. Rather than finding support for its conclusion in the
    provisions of Tennessee’s version of the Code of Professional Responsibility which
    governed the conduct of the lawyers in the case, the court based its opinion on
    provisions of the ABA Model Rules of Professional Conduct and on decisions by
    the United States Court of Appeals for the Seventh Circuit.
    The Manning decision prompted another request for a formal ethics opinion
    regarding the efficacy of screening arrangements by Tennessee lawyers. On this
    occasion, the Board of Professional Responsibility reversed itself and overruled
    Page 25
    Formal Opinions 81-F-5 and 87-F-110. Without addressing Tenn. S. Ct. R. 8, DR
    5-105(D), the Board found that the presumptions of shared confidences at an
    attorney’s new firm could be rebutted by proof that the attorney’s new firm had
    instituted appropriate screening arrangements.       See Tenn. Bd. of Professional
    Responsibility, Formal Op. 89-F-118. 68      The Board also stated that screening
    arrangements could be used for lawyers, law clerks, paralegals, and legal secretaries.
    Tennessee’s intermediate appellate courts have taken different paths with
    regard to imputed disqualification and the efficacy of screening mechanisms. This
    difference can be explained, at least in part, by the distinction between lawyers in
    government service and those in private practice and by the difference between
    criminal proceedings and civil proceedings. The cases reflect an understanding that
    applying the imputed disqualification doctrine to district attorney generals’ offices in
    the same way that it is applied to private law firms would seriously hamper the
    prosecution of criminal cases. See State v. West, No. 01C01-9107-CC-00202, 
    1992 WL 62020
    , at *2 (Tenn. Crim. App. Mar. 31, 1992), perm. app. dismissed, (Tenn.
    July 13, 1992).
    In the earliest reported imputed disqualification case, the Tennessee Court of
    Criminal Appeals declined to disqualify a district attorney general and his entire staff
    because one assistant district attorney had peripherally represented the defendants
    while employed as a staff attorney at the University of Tennessee Legal Clinic.
    Without much discussion, the court held that while the assistant district attorney
    general formerly employed at the legal clinic should be disqualified, the remaining
    members of the district attorney general’s office were not disqualified. See Mattress
    v. State, 
    564 S.W.2d 678
    , 679-80 (Tenn. Crim. App. 1977). Seven years later, the
    court reversed a second degree murder conviction because the defendant’s former
    lawyer switched sides and assisted the prosecution of the defendant as an assistant
    district attorney general. In its remand order, the court disqualified not just the
    assistant but also the district attorney general’s entire staff. See State v. Phillips,
    
    672 S.W.2d at 436
    .
    Page 26
    In 1992, the Court of Criminal Appeals, adopting Formal Op. 89-F-118, held
    that a district attorney general could avoid the imputed disqualification of the entire
    office by proving “by clear and convincing evidence that the challenged attorney has
    been sufficiently screened from the remainder of the staff and its work on the
    pending case.”     See State v. Claybrook, 
    1992 WL 17546
    , at *11.            After the
    Claybrook decision, the court has consistently declined to disqualify a district
    attorney general’s entire staff when timely screening arrangements have been
    instituted 69 and has reversed convictions when they have not. 70
    The Court of Appeals has had less occasion to confront imputed
    disqualification issues than the Court of Criminal Appeals. The first case presenting
    the issue involved a divorce proceeding in which the secretary of a lawyer
    representing the wife took a job with the lawyer representing the husband. The court
    reversed the trial court’s disqualification of the husband’s lawyer on two grounds.
    First, a majority of the court announced that “[n]o Supreme Court Rule or Statute is
    cited or found which forbids a lawyer to hire a former secretary of a lawyer who
    opposes him in a lawsuit.” Second, the court found that no evidence had been
    presented that the secretary had shared any of the wife’s confidential information
    with the husband’s lawyer. See King v. King, 
    1989 WL 122981
    , at *9.                The
    majority of the court downplayed the significance of both Formal Op. 89-F-118 and
    screening arrangements by observing that the ethics opinion was not binding on the
    courts and that use of screening arrangements had not been made part of Tenn. S.
    Ct. R. 8. See King v. King, 
    1989 WL 122981
    , at *10.
    The court never reached the issue of screening arrangements in the second
    case raising the issue of imputed disqualification. The case was an encroachment
    action in which one property owner moved to disqualify the lawyer representing the
    neighboring property owner because one of the lawyer’s partners had represented
    the moving party when she bought the property at auction. Both the trial court and
    the appellate court declined to disqualify the lawyer after finding that there was no
    Page 27
    substantial relationship between the closing and the later encroachment action and
    that the party seeking the disqualification had not divulged any confidential
    information during or before the closing. See Lemm v. Adams, 
    955 S.W.2d 70
    , 75
    (Tenn. Ct. App. 1997).
    The most recent case considered by the Court of Appeals required the court
    to   consider the efficacy of screening arrangements established when a lawyer
    representing one of the defendants in a medical malpractice action left his firm to
    start a new firm with the lawyers representing the plaintiffs in the same case. Before
    the lawyer left his old firm, he requested that he be insulated from any further
    activities in the case. He also reached an understanding with his new partners that
    they would institute screening arrangements to isolate him from the case. 71 Despite
    these screening arrangements, the trial court disqualified the law firm representing the
    plaintiffs because the small size of the firm rendered screening ineffective. The court
    ’s decision to affirm the trial court’s disqualification order rested on Tenn. S. Ct. R.
    8, Canon 9. The court stated:
    In the case before us, the lawyers carefully planned their
    joinder – a calculated and deliberate act with full
    knowledge that Pierce possessed the most intimate
    confidence of his client concerning the case. They argue
    that the screening procedures rebut the presumption of
    Pierce sharing these confidences. The new firm is small,
    and we hope the firm has the collegiality that typifies the
    brotherhood 72 of the profession. In such an atmosphere, it
    is certainly conceivable that at best inadvertent references
    to the case could crop up from time to time. Who knows
    what effects such references might have on plaintiffs’
    lawyers in perhaps following some lead that was
    innocently, perhaps, fostered by some comment made
    without any improper motive. Leaving aside the possibility
    of divulged confidences, we are still faced with the
    appearance of impropriety. As in the Penn Mutual case, 73
    the lawyers in the case before us “switched sides.”
    We . . . believe that Canon 9 is essential to engender,
    protect, and preserve the trust and confidence of the client.
    In the case before us with these peculiar facts, we cannot
    say that the trial court erred in disqualifying plaintiffs’
    Page 28
    lawyers from further participation in the case. The
    profession demands, and the public deserves, no less.
    Watson v. Ameredes, No. 03A01-9704-CV-00129, 
    1997 WL 772865
    , at *6-7 (Tenn.
    Ct. App. Dec. 10, 1997) (No Tenn. R. App. P. 11 application filed).
    VI.
    Disqualifying a party’s lawyer is a drastic remedy that should be used
    sparingly.    See Lemm v. Adams, 955 S.W.2d at 74; Hilton v. Crawford, No.
    03A01-9101-CV-00033, 
    1991 WL 261872
    , at *3 (Tenn. Ct. App. Dec. 13, 1991)
    (No Tenn. R. App. P. 11 application filed).           The courts should carefully and
    critically scrutinize disqualification motions because of (1) their disruptive effect on
    the trial process, 74 (2) their interference with a party’s right to retain counsel of their
    own choosing, and (3) the legitimate concern that the motion is filed simply to gain a
    tactical advantage at trial.75 Thus, the courts should be reluctant to disqualify a party
    ’s lawyer and should do so only when no other satisfactory remedy exists. See
    Whalley Dev. Corp. v. First Citizens Bancshares, Inc., 
    834 S.W.2d 328
    , 331-32
    (Tenn. Ct. App. 1992); In re Ellis, 822 S.W.2d at 605.
    No bright-line tests exist for making disqualification decisions when a lawyer
    has received confidential information. See In re Meador, 
    968 S.W.2d 346
    , 351
    (Tex. 1998). These decisions should be made on a case-by-case basis in light of the
    facts of the particular case. See Watson v. Ameredes, 
    1997 WL 772865
    , at *4; State
    v. Tate, 925 S.W.2d at 557. Because these decisions are fact-driven, it is preferable
    for the trial court to conduct an evidentiary hearing rather than making a decision
    based only on affidavits. See Chrispens v. Coastal Ref’g & Mktg., Inc., 
    897 P.2d 104
    , 116 (Kan. 1995); Piette v. Bradley & Leseberg, 
    930 P.2d 183
    , 184 (Okla.
    1996).
    Decisions regarding disqualification are discretionary and are thus entitled to
    deference on appeal. See Rust v. Gerbman, No. 01A01-9608-CH-00361, 1997 WL
    Page 29
    266844, at *6 (Tenn. Ct. App. May 21, 1997) (No Tenn. R. App. P. 11 application
    filed); State v. Tate, 925 S.W.2d at 549-50; State v. Phillips, 
    672 S.W.2d at 431
    .
    However, when the facts are essentially undisputed, the trial courts are no better
    suited than the appellate courts to construe the ethics rules. Thus, the appellate
    courts are not required to defer to a trial court’s interpretation of the Code of
    Professional Responsibility or to its decisions regarding the legal standards
    applicable to a particular disqualification motion. See In re Ellis, 822 S.W.2d at
    606.
    Both intermediate appellate courts and the Board of Professional
    Responsibility have determined that the three-part test fashioned by the United States
    Court of Appeals for the Seventh Circuit in Schiessle v. Stephens is an appropriate
    method for addressing imputed disqualification questions. See Lemm v. Adams, 955
    S.W.2d at 74; State v. Tate, 925 S.W.2d at 557-58; State v. Claybrook, 
    1992 WL 17546
    , at *10; Tenn. Bd. of Professional Responsibility, Formal Op. 89-F-118.
    This approach requires the courts to consider the three questions. The threshold
    question is whether a substantial relationship exists between the present and the
    former representation. If a substantial relationship exists, the second and third
    questions are whether the presumption of shared confidences with respect to the
    former representation has been rebutted and whether the presumption of shared
    confidences with respect to the current representation has been rebutted.            See
    Schiessle v. Stephens, 
    717 F.2d at 420
    .
    While courts in other jurisdictions differ concerning the criteria for determining
    whether a substantial relationship exists between the former and present
    representation, we need not address this issue in this case because the undisputed
    facts lead to no conclusion other than that there is a substantial relationship between
    the present and former representation.       They are, in fact, the same case.       An
    affirmative answer to this threshold question would normally give rise to the
    presumption that a lawyer was privy to the confidences and secrets of clients of his
    or her former firm. However, under the facts of this case, we need not rely on the
    Page 30
    presumption because it is undisputed that Mr. Davis was the Blackwoods’ attorney
    of record in this case and that he obtained privileged information from them in order
    to prepare their answer and counterclaim against the Clinards. Accordingly, the
    answers to the first two questions of the Schiessle analysis favor the Blackwoods’
    recusal motion.
    If the presumption of shared confidences were irrebuttable, our inquiry would
    end here because Tenn. S. Ct. R. 8, DR 5-105(D) would require the imputed
    disqualification of the entire Waller firm because of Mr. Davis’s direct, personal
    conflict of interest. However, for the purposes of this appeal, we will assume that
    the presumption of shared confidences at a lawyer’s new firm is rebuttable even
    though the Tennessee Supreme Court has not yet decided the issue. Virtually all
    intermediate appellate court decisions addressing the imputed disqualification issue
    during the past ten years have held the presumption of shared confidences between a
    lawyer and his or her new firm is rebuttable. Thus, the question becomes whether
    evidence that a private firm has employed internal screening arrangements will suffice
    to rebut the presumption in every case. The answer to this question is no.
    Even though we share many of the expressed qualms regarding screening
    arrangements, 76 we will assume for the sake of this opinion that a properly instituted
    and maintained screening arrangement can provide evidence to rebut the
    presumption of shared confidences in certain circumstances. Thus, the questions to
    be answered are under what circumstances will screening arrangements have the
    desired effect and for which lawyers may screening arrangements be used.
    The prevailing view, and the view that most appropriately balances the
    competing interests when an imputed disqualification issue surfaces, is that a
    screening arrangement may be used to prevent the disqualification of a law firm only
    when the personally conflicted lawyer was superficially involved with the former
    client. In this circumstance, the risk of intentional or inadvertent disclosure of
    confidential information that could materially prejudice a former client is greatly
    Page 31
    minimized. This view furthers clients’ legitimate expectations that their lawyer will
    protect their confidences and secrets 77 and that their lawyer will represent them with
    undivided loyalty within the bounds of the law.78 This view is also implicit in both
    the ABA Model Rules of Professional Conduct Rules 1.09, 1.10 79 and Restatement
    (Third) of the Law Governing Lawyers § 204(2) (Proposed Final Draft No. 1 1996). 80
    Under the prevailing view, which is also consistent with Watson v. Ameredes,
    the Waller firm’s use of a screening arrangement to shield the rest of the firm from
    Mr. Davis and his secretary does not suffice to prevent the operation of the imputed
    disqualification rule. Mr. Davis has not been on the periphery of representing the
    Blackwoods. They were former clients whom he actively represented from 1973
    through August 1996. He actually represented the Blackwoods in the very case in
    which Waller, Lansden, Dortch and Davis is now representing their adversaries.
    During Mr. Davis’s representation of the Blackwoods in this case, which lasted from
    March through August 1996, the Blackwoods provided Mr. Davis with confidential
    information directly relevant and material to both their defense against the Clinard’s
    boundary line complaint, their counterclaims against the Clinards and their third-party
    claims against American Limestone.
    The Blackwoods were the ones required to retain a new lawyer in 1996 when
    Mr. Davis withdrew after another client of his firm declined to permit him to continue
    to pursue the Blackwoods’ legal remedies. After they retained a new lawyer, they
    discovered that Mr. Davis had joined the law firm that was representing their
    adversaries in the same case in which he had once been their attorney of record. Mr.
    Davis never informed the Blackwoods that he was negotiating a return to the Waller
    firm, made no effort to obtain their consent, and provided them with no assurance in
    advance that his return to the Waller firm would not materially affect their claims and
    defenses in the dispute with the Clinards and American Limestone. Under these
    circumstance, the Blackwoods’ perception that Mr. Davis had essentially “switched
    sides” in the litigation is not unfounded or unreasonable.
    Page 32
    Our resolution of this appeal must track the Code of Professional
    Responsibility as enacted in Tennessee rather than the provisions of the ABA Model
    Rules of Professional Conduct which have not yet even been considered by the
    Court. Thus, Tenn. S. Ct. R. 8, Canon 9, even if disfavored by some factions of
    the organized bar, remains an important factor when addressing imputed conflict of
    interest issues. See Watson v. Ameredes, 
    1997 WL 772865
    , at * 6-7; State v. Tate,
    925 S.W.2d at 555. 81 As one experienced federal trial judge recently noted, “[i]n an
    age of sagging public confidence in our legal system, maintaining confidence in that
    system and the legal profession is of utmost importance.” Roberts & Schaefer Co.
    v. San-Con, Inc., 898 F. Supp. at 363. This settled purpose was recently echoed by
    Judge Crawford when he noted that it is essential for the courts to “engender,
    protect, and preserve the trust and confidence of the client.” Watson v. Ameredes,
    
    1997 WL 772865
    , at *7.
    Based on the facts of this case and for the reasons stated herein, we find that
    the Waller firm’s use of screening arrangements with regard to Mr. Davis and his
    secretary was not sufficient to rebut the presumption of shared confidences between
    Mr. Davis and the other members of the Waller firm with the regard to the pending
    litigation between the Blackwoods and the Clinards and American Limestone.
    Accordingly, the trial court erred by denying the Blackwoods’ motion to disqualify
    the Waller firm from continuing to represent the Clinards and American Limestone in
    this case.
    VII.
    We vacate the order denying the Blackwoods’ motion to disqualify the firm of
    Waller, Lansden, Dortch & Davis in this case and remand the case to the trial court
    with directions to enter an order disqualifying the firm. We tax the costs of this
    appeal to Waller, Lansden, Dortch & Davis for which execution, if necessary, may
    issue.
