    129 T.C. No. 6
    UNITED STATES TAX COURT
    THOMAS J. AND BONNIE F. RATKE, Petitioners v.
    COMMISSIONER OF INTERNAL REVENUE, Respondent*
    Docket No. 9641-01L.                Filed September 5, 2007.
    After this Court ruled for Ps in the instant
    collection case, Ps moved for an award of costs under
    sec. 7430, I.R.C. 1986, and then for sanctions under
    sec. 6673(a)(2), I.R.C. 1986. In connection with these
    motions, Ps seek discovery of (1) a memorandum sent by
    R’s initial trial counsel to R’s national office at the
    time R’s answer was filed in the instant case and (2)
    the unredacted version of the responding memorandum
    sent a few months later by R’s national office. R
    provided to Ps a redacted version of the latter
    memorandum. R resists discovery of the unredacted
    memoranda, claiming work product doctrine privilege.
    *
    This opinion supplements Ratke v. Commissioner, 
    T.C. Memo. 2004-86
    .
    - 2 -
    Ps contend (1) the memoranda are not work product
    at the current stage of the litigation; (2) Ps are
    entitled to discovery even if the memoranda are work
    product; and (3) R waived the privilege.
    1. Held: Both memoranda were work product when
    prepared for the case in chief and continue to be work
    product in the current stage of the litigation.
    2. Held, further, having examined both memoranda
    in camera, we conclude that neither memorandum contains
    information sufficiently important to outweigh the
    privacy and other concerns underlying the work product
    doctrine.
    3. Held, further, R’s brief reference in the
    motion papers to the memoranda, but not to either
    memorandum’s contents, does not amount to a
    “testimonial” use of either memorandum that would
    constitute an implied waiver of the work product
    doctrine privilege.
    Jack B. Schiffman, for petitioners.
    Robert M. Fowler, for respondent.
    OPINION
    CHABOT, Judge:   This matter is before us on petitioners’
    Motion for Award of Reasonable Litigation and Administrative
    Costs Under Section 74301 as well as petitioners’ Motion for
    Sanctions Under Section 6673(a)(2) in the instant collection
    proceeding.   The issue for decision is whether two memoranda
    1
    Unless indicated otherwise, all section references are to
    sections of the Internal Revenue Code of 1986 as in effect for
    proceedings commenced on the day the petition in the instant case
    was filed.
    - 3 -
    prepared in connection with the case in chief are protected from
    discovery under the work product doctrine privilege in connection
    with these motions.
    Background
    When the petition was filed in the instant case, petitioners
    resided in Glendale, Arizona.
    Petitioners timely filed their 1993 Federal income tax
    return.   Petitioners showed a $9,238 tax liability for 1993.    On
    January 9, 1996, respondent sent to petitioners a notice of
    deficiency that determined a $20,710 deficiency (liability of
    $29,948, minus the $9,238 liability shown on petitioners’ tax
    return) and a $4,142 penalty under section 6662(a).   On March 29,
    1996, petitioners sent a petition to the Court (docket No. 5931-
    96, hereinafter sometimes referred to as the 1996 case) disputing
    the entire amounts of the deficiency and penalty so determined.
    Also on March 29, 1996, petitioners sent to respondent a
    second amended 1993 tax return (Form 1040X, Amended U.S.
    Individual Income Tax Return) showing a tax liability of $21,893,
    and showing that this was $12,655 greater than the liability they
    had previously reported.   On May 27, 1996, respondent made an
    additional assessment of the $12,655 shown on this Form 1040X,
    along with interest, and notified petitioners of this additional
    assessment.
    - 4 -
    The parties settled the 1996 case and, on March 13, 1997,
    the Court entered a decision pursuant to the parties’ stipulated
    agreement that petitioners had a $2,931 deficiency and no
    “addition to tax” under section 6662(a).   On May 19, 1997,
    respondent assessed this $2,931 deficiency and sent to
    petitioners a notice and demand for $21,164.
    On September 20, 2000, respondent sent to petitioners a
    Final Notice - Notice of Intent to Levy and Notice of Your Right
    to a Hearing relating to 1993.    On October 17, 2000, petitioners
    filed Form 12153, Request for a Collection Due Process Hearing.
    On June 28, 2001, respondent mailed to petitioners a Notice of
    Determination Concerning Collection Action(s) Under Section 6320
    and/or 6330.   On July 31, 2001, petitioners filed their petition
    in the instant case.   On August 7, 2001, petitioners filed an
    amended petition.   On September 6, 2001, respondent filed the
    answer to this amended petition.    This answer was signed by Ann
    M. Welhaf (hereinafter sometimes referred to as Welhaf), Acting
    Associate Area Counsel, and dated September 5, 2001.   Welhaf also
    prepared a memorandum dated September 5, 2001, addressed to:
    Assistant Chief Counsel, Procedure and Administration, Collection
    Bankruptcy and Summons, Attn:    Alan Levine, Chief Branch 1, CBS.
    - 5 -
    This memorandum, hereinafter sometimes referred to as the Welhaf
    memorandum, is summarized by respondent as follows:2
    This memorandum is a request for advice from Ms.
    Welhaf to the Office of Associate Chief Counsel
    (Procedure & Administration) of respondent’s National
    Office concerning proposed legal arguments to be made
    at trial in the pending litigation. This request was
    made while this case was docketed. The author
    recommends several legal arguments to be made in the
    litigation subject to National Office approval. The
    memorandum also sets forth the factual background
    concerning this case.
    Mitchell S. Hyman, Senior Technical Reviewer, Branch 1,
    Collection, Bankruptcy and Summons, sent a memorandum dated
    January 16, 2002 (hereinafter sometimes referred to as the Hyman
    memorandum), which is summarized by respondent as follows:3
    This memorandum responded to Ms. Welhaf’s
    September 5, 2001 memorandum seeking advice concerning
    the proposed legal arguments to be made at trial in the
    pending litigation. The January 16, 2002 memorandum
    concluded that: (1) the IRS was authorized by section
    6201(a)(1) to make an assessment pursuant to the
    amended return filed by petitioners; (2) petitioners
    were equitably estopped from contesting the validity of
    the assessment; (3) the stipulated settlement was a
    valid contract; (4) the amended return did not

    Pursuant to the Court’s order respondent provided the
    Welhaf memorandum to the Court for in camera inspection, together
    with a summary; the summary was filed and served on petitioners.
    After inspecting the Welhaf memorandum, the Court concludes that
    respondent’s summary is a fair description of the Welhaf
    memorandum.
    3
    Pursuant to the Court’s order respondent provided the
    unredacted Hyman memorandum to the Court for in camera
    inspection, together with a summary; the summary was filed and
    served on petitioners. After inspecting the unredacted Hyman
    memorandum, the Court concludes that respondent’s summary is a
    fair description of the unredacted Hyman memorandum.
    - 6 -
    constitute a waiver of the restrictions on assessment;
    and (5) that petitioners were not precluded by section
    6330(c)(2)(B) from arguing that the assessment violated
    section 6213(a).
    On June 13, 2002, the Court issued a notice of trial in the
    instant case.   In due course:   the instant case was continued,
    the instant case was again set for trial, the Court dealt with
    motions by both sides, the trial was held, briefs were filed, the
    Court issued 
    T.C. Memo. 2004-86
     holding for petitioners, and the
    Court entered decision “that respondent may collect only $2,931
    for taxable year 1993 as set forth in the Court’s March 13, 1997,
    decision [the decision that ended the 1996 case].”
    On petitioners’ motion this decision was vacated;
    petitioners then moved for an award of costs under section 7430
    and later moved for sanctions under section 6673(a)(2).    At some
    point, respondent provided to petitioners a redacted version of
    the Hyman memorandum.   In connection with the latter motions, the
    parties have stipulated the redacted Hyman memorandum.
    Petitioners now seek to discover the unredacted Welhaf
    memorandum and the unredacted Hyman memorandum.    Respondent
    claims that the memoranda are protected work product and refuses
    petitioners’ discovery requests.    We directed respondent to
    submit these memoranda for in camera inspection along with an
    explanation of why the memoranda should not be disclosed to
    petitioners in whole or in part.    (See supra notes 2 and 3.)
    - 7 -
    Both the Welhaf memorandum and the Hyman memorandum were
    prepared as part of respondent’s counsel’s efforts to prepare
    legal theories and plan strategy for the instant case.
    Discussion
    A.   Preliminary
    Petitioners want to discover the Welhaf memorandum and the
    unredacted Hyman memorandum.   See Rules 70,4 72.   Respondent
    objects to discovery of these memoranda on the ground that both
    memoranda are privileged.   See Rule 70(b)(1).   A party opposing
    discovery on such a ground has the burden of establishing that
    the information sought is privileged.    Ames v. Commissioner, 
    112 T.C. 304
    , 309 (1999); Bernardo v. Commissioner, 
    104 T.C. 677
    , 691
    (1995).   The privilege respondent claims is the one resulting
    from the work product doctrine.   See Rules Committee Notes, 
    60 T.C. 1058
    , 1098.
    If the party opposing discovery establishes that the
    information sought is work product, then discovery will not be
    required unless the Court determines that, in the situation
    before it, the information sought should nevertheless be
    disclosed.   Hickman v. Taylor, 
    329 U.S. 495
    , 512 (1947); Ames v.
    Commissioner, 
    112 T.C. at 310-311
    .

    Tax Court Rules of Practice and Procedure.
    - 8 -
    B.   Parties’ Contentions
    Respondent contends that both (1) the entire Welhaf
    memorandum and (2) the redacted portions of the Hyman memorandum
    are protected from discovery pursuant to the work product
    doctrine.    Respondent maintains that (a) both memoranda are work
    product, (b) to the extent the memoranda include “fact” work
    product, petitioners cannot show a substantial need or undue
    hardship because “they are well aware of all the facts in this
    case”, and (c) to the extent the memoranda include “opinion” work
    product the memoranda are “absolutely protected from disclosure”
    or in any event are not disclosable because petitioners “have not
    made a far stronger showing than the ‘substantial need’ and
    ‘without undue hardship’ standard”.
    Petitioners assert that the work product doctrine is not
    absolute, relying on rule 26(b)(3) of the Federal Rules of Civil
    Procedure.   They contend that (1) they need to have access to the
    Welhaf memorandum in order to determine whether “Welhaf ‘cherry
    picked’ the facts favorable to her position, and did not include
    facts unfavorable to her position”, (2) this information would be
    relevant to (a) “substantial authority under I.R.C.
    §7430(c)(4)(B)” and (b) “sanctionable misconduct under I.R.C.
    §6673(a)(2)”, and (3) Rule 91(a)(1) has the effect of requiring
    disclosure so that the parties can stipulate to the matters
    relevant to the motions before the Court.   Petitioners contend
    - 9 -
    that the same considerations apply to the unredacted Hyman
    memorandum.     Petitioners also maintain that the memoranda were
    prepared for “the case in chief” and are not work product with
    respect to “the post-decision application for litigation costs
    and sanctions”.    Finally, petitioners maintain that respondent’s
    efforts to use the redacted version of the Hyman memorandum “as
    support for its claim of substantial justification under I.R.C.
    §7430(c)(4)(B)” should be treated as a waiver of the work product
    doctrine privilege for the entire Hyman memorandum.
    C.   Summary and Conclusions
    Both the Welhaf memorandum and the Hyman memorandum are work
    product and so are privileged.     The privilege is qualified.   We
    examined both memoranda in camera and conclude that (1)
    exceptions to this privilege do not apply and (2) this privilege
    has not been waived.     Accordingly, neither memorandum is required
    to be disclosed in the present proceeding.
    D.   Analysis
    1.   In General
    We set forth this Court’s general view of the work product
    doctrine in P.T. & L. Construction Co. v. Commissioner, 
    63 T.C. 404
    , 407-408 (1974), as follows:
    The work product doctrine was given its first thorough
    exposition in the Federal courts in Hickman v. Taylor,
    - 10 -
    
    329 U.S. 495
     (1947).[5] In that case the Supreme Court
    held that materials prepared in anticipation of
    litigation, including witness’ statements, were not
    subject to discovery as a matter of right because such
    discovery would be harmful to the orderly prosecution
    and defense of legal claims in adversary proceedings.
    “Work product,” as a term of art, is used to describe
    such protected materials. See Hickman v. Taylor, 
    supra at 510
    .
    The holding in Hickman v. Taylor, 
    supra,
     has been
    specifically incorporated in the Federal Rules of Civil
    Procedure as rule 26(b)(3). Further, the work product
    doctrine is given negative recognition in the Tax Court
    Rules of Practice and Procedure in that, even though it
    is not mentioned in the body of the Rules, it is dealt
    with in the notes of our Rules Committee to Rule 70(b).
    These notes state, in pertinent part, as follows:
    The other areas, i.e., the “work product” of
    counsel and material prepared in anticipation
    of litigation or for trial, are generally
    intended to be outside the scope of allowable
    discovery under these Rules, and therefore
    the specific provisions for disclosure of
    such materials in FRCP 26(b)(3) have not been
    adopted. Cf. Hickman v. Taylor, 
    329 U.S. 495
    (1947). [
    60 T.C. 1098
    .]
    2.   Are the Memoranda Work Product?
    The Welhaf memorandum describes Welhaf’s intended arguments
    in defending the instant case and asks for concurrences or
    opinions regarding these intended arguments.   The Hyman
    memorandum responds to the elements of the Welhaf memorandum.
    The Welhaf memorandum was sent about the time respondent filed
    5
    For a summary of the discovery evolution that led to
    Hickman v. Taylor, 
    329 U.S. 495
     (1947), and interpretations of
    the law since 1947, see 8 Wright, Miller & Marcus, Federal
    Practice and Procedure: Civil 2d secs. 2021-2028; that treatise
    and its most recent pocket part are hereinafter sometimes
    referred to as Wright, Miller & Marcus.
    - 11 -
    the answer in the instant case.     The Hyman memorandum was sent
    before the instant case was first noticed for trial.     Thus, both
    memoranda were prepared as part of respondent’s counsels’ efforts
    to “prepare * * * legal theories and plan * * * strategy” for the
    instant case.   Hickman v. Taylor, 
    329 U.S. at 511
    .    It follows
    that both memoranda are work product for the instant case.
    Petitioners contend that both memoranda were prepared for
    “the case in chief” and are not work product with respect to “the
    post-decision application for costs and sanctions”.     We disagree.
    Firstly, the instant case is the same litigation for which
    the memoranda were prepared.   The litigation for which the
    memoranda were prepared will not be concluded, by entry of
    decision, until petitioners’ motions under sections 7430 and
    6673(a)(2) have been dealt with.6    We have not found, and
    petitioners have not directed our attention to, any case law
    indicating that one lawsuit should be segmented for purposes of
    determining whether a document is work product.
    Secondly, in Ames v. Commissioner, supra, we dealt with a
    document prepared by the Commissioner’s counsel in anticipation
    of criminal tax prosecution.   The taxpayer sought production of
    6
    Rule 232(f) provides that the disposition of the sec. 7430
    motion “shall be included in the decision entered in the case.”
    Indeed, when the Court entered decision for petitioners in the
    instant case after issuing 
    T.C. Memo. 2004-86
    , petitioners moved
    to vacate the decision so that they would be permitted to file
    their sec. 7430 motion.
    - 12 -
    that document in the civil tax proceeding that followed the
    criminal tax case.    We concluded in Ames that there was
    sufficient nexus between the criminal litigation for which the
    document had originally been prepared, and the civil litigation
    before this Court, so that the document qualified as work product
    in the civil litigation.    Ames v. Commissioner, 
    112 T.C. at
    309-
    310.
    Additionally, the Court of Appeals for the Tenth Circuit
    noted that “it appears every circuit to address the issue has
    concluded that, at least to some degree, the work product
    doctrine does extend to subsequent litigation.”    Frontier
    Refining Inc. v. Gorman-Rupp Co., 
    136 F.3d 695
    , 703 (10th Cir.
    1998 (and cases cited therein).    Compare the foregoing with Hartz
    Mountain Industries v. Commissioner, 
    93 T.C. 521
    , 527-528 (1989),
    in which we concluded that the fact that “the work product at
    issue was prepared approximately a decade ago in distinctly
    different litigation” was one of three factors that collectively
    led us to rule that the work product doctrine privilege did not
    protect against disclosure in that case.    In this respect, the
    instant case is clearly distinguishable from Hartz Mountain
    Industries.    A fortiori, a document prepared for the same
    litigation, as in the instant case, qualifies as work product.
    See discussion in Ames v. Commissioner, 
    112 T.C. at
    310 & n.4;
    - 13 -
    see also Bernardo v. Commissioner, 
    104 T.C. at
    688 n.14.       See
    generally Wright, Miller & Marcus, sec. 2024 nn. 12-15.
    We hold that both memoranda are work product for purposes of
    the litigation as to petitioners’ motions under sections 7430 and
    6673.
    3.    Extent of the Privilege
    The privilege resulting from the work product doctrine7 is
    qualified; it may be overcome by an appropriate showing.       Ames v.
    Commissioner, 
    112 T.C. at 310
    ; Hartz Mountain Industries v.
    Commissioner, 93 T.C. at 527 (1989).    Rule 26(b)(3) of the
    Federal Rules of Civil Procedure requires a showing of
    “substantial need” and an inability to otherwise obtain the
    substantial equivalent “without undue hardship”; that rule sets
    aside “disclosure of the mental impressions, conclusions,
    opinions, or legal theories of an attorney or other
    representative of a party concerning the litigation.”
    As to such opinion work product, the Court of Appeals for
    the Ninth Circuit, to which the instant case is appealable, has
    summarized the standards in Holmgren v. State Farm Mut. Auto.
    Ins. Co., 
    976 F.2d 573
    , 577 (9th Cir. 1992), as follows:
    A party seeking opinion work product must make a
    showing beyond the substantial need/undue hardship test
    required under Rule 26(b)(3) for non-opinion work
    product. Upjohn Co. v. United States, 
    449 U.S. 383
    ,
    401-02, 
    101 S.Ct. 677
    , 688-89, 
    66 L.Ed.2d 584
     (1981).
    7
    See Wright, Miller & Marcus, sec. 2025, nn. 3, 4, and 5.
    - 14 -
    The Supreme Court, however, has so far declined to
    decide whether opinion work product is absolutely
    protected from discovery. 
    Id. at 401
    , 
    101 S.Ct. at 688
    .
    *     *     *     *       *   *     *
    We agree with the several courts and commentators
    that have concluded that opinion work product may be
    discovered and admitted when mental impressions are at
    issue in a case and the need for the material is
    compelling. * * *
    Both elements are met here. In a bad faith
    insurance claim settlement case, the “strategy, mental
    impressions and opinion of [the insurer’s] agents
    concerning the handling of the claim are directly at
    issue”. * * * Further, Holmgren’s need for the exhibits
    was compelling. * * *
    See generally Wright, Miller & Marcus, sec. 2026.
    Petitioners contend that our Rule 91(a)(1)8 “requires
    Respondent to provide Ms. Welhaf’s Memorandum in its entirety so
    8
    Rule 91(a)(1) provides, in pertinent part, as follows:
    RULE 91.    STIPULATIONS FOR TRIAL
    (a) Stipulations Required: (1) General: The
    parties are required to stipulate, to the fullest
    extent to which complete or qualified agreement can or
    fairly should be reached, all matters not privileged
    which are relevant to the pending case, regardless of
    whether such matters involve fact or opinion or the
    application of law to fact. Included in matters
    required to be stipulated are all facts, all documents
    and papers or contents or aspects thereof, and all
    evidence which fairly should not be in dispute. * * *
    The requirement of stipulation applies under this Rule
    without regard to where the burden of proof may lie
    with respect to the matters involved. Documents or
    papers or other exhibits annexed to or filed with the
    stipulation shall be considered to be part of the
    stipulation.
    - 15 -
    that counsel can stipulate as to which facts were set forth and
    which facts were not set forth (omitted) in Ms. Welhaf’s
    Memorandum to the Chief Counsel’s Office.”    Respondent contends:
    8.   As far as Ms. Welhaf’s opinion work product is concerned, it
    is respondent’s view that such opinion work product is absolutely
    protected from disclosure.    We reject both sides’ contentions
    insofar as they would preclude us from conducting an appropriate
    balancing of interests in section 7430 and section 6673(a)(2)
    disputes.
    We decline to adopt either side’s approach.   In an effort to
    give meaningful effect to the relevant public policies in a
    practical way in the instant case, we chose to conduct in camera
    inspections of the two unredacted memoranda.    We recognize that
    other courses of action may be preferable in other circumstances.
    4.    Application to This Case
    Having conducted an in camera review of the Welhaf
    memorandum and the unredacted Hyman memorandum, we conclude there
    is neither a substantial need to discover any of the fact-based
    work product nor compelling need to discover any of the opinion
    work product.
    A redacted version of the Hyman memorandum was provided to
    petitioners.    The redacted version of the Hyman memorandum
    discloses the statements about matters of fact, but not all of
    the legal strategies or opinions, set forth in the unredacted
    - 16 -
    Hyman memorandum.   The statements about matters of fact presented
    in the redacted memorandum are identical to those presented in
    the unredacted Hyman memorandum.   Petitioners have the redacted
    version of the Hyman memorandum, and so we conclude that
    petitioners are in possession of the fact-based work product.     We
    further conclude that, as to the legal strategies and opinions,
    the redacted version of the Hyman memorandum and respondent’s
    summary of the unredacted version of the Hyman memorandum (supra
    notes 2, 3, and 7) taken together provide a fair representation
    of the legal strategies and opinions in the unredacted version of
    the Hyman memorandum.   Because (1) petitioners were provided with
    a fair representation of the unredacted legal strategies and
    opinions, and (2) the redacted portions would not impact the
    outcome of petitioners’ motions under sections 7430 and 6673 in
    the instant case, we conclude that petitioners do not have a
    compelling need to discover this opinion work product;
    petitioners’ desire to discover the unredacted version of the
    Hyman memorandum is outweighed by the protection afforded by the
    privacy privilege under the work product doctrine.
    The Welhaf memorandum presents statements about matters of
    fact that are substantially similar to those presented in the
    redacted version of the Hyman memorandum.   Because petitioners
    are already in possession of the equivalent fact-based work
    product (in the form of the redacted version of the Hyman
    - 17 -
    memorandum), we conclude that petitioners have neither a
    substantial need to discover the fact-based work product in the
    Welhaf memorandum nor an inability to obtain a substantial
    equivalent of this fact-based work product without incurring
    undue hardship.
    The Welhaf memorandum suggests and analyzes various
    positions respondent might take in the litigation in the instant
    case.   There is no “smoking gun” in the Welhaf memorandum
    establishing that respondent’s position in the underlying
    litigation was not substantially justified and thereby possibly
    entitling petitioners to litigation costs under section 7430.
    Nor is there a “smoking gun” in the Welhaf memorandum that would
    prove respondent’s attorney unreasonably and vexatiously
    multiplied the proceedings, and thereby entitle petitioners to
    litigation costs under section 6673(a)(2).   Because the Welhaf
    memorandum would not impact the outcome of petitioners’ motions
    under sections 7430 and 6673 in the instant case, we conclude
    there is no compelling need to discover the memorandum;
    petitioners’ desire to discover the Welhaf memorandum is
    outweighed by the protection afforded by the privacy privilege
    under the work product doctrine.
    Accordingly, we sustain respondent’s contention that the
    work product doctrine privilege protects both memoranda from
    discovery.

    5.   Waiver
    Petitioners contend that, even if the memoranda were
    privileged under the work product doctrine, respondent should be
    treated as having waived the privilege, because:
    To permit Respondent to withhold Ms. Welhaf’s factual
    representation to the Chief Counsel’s Office from the
    Ratkes would allow Respondent to use the work product
    doctrine as both a “sword and shield litigation tactic”
    in this post-decision proceeding for litigation costs
    and sanctions. As opined by the Federal Circuit in
    EchoStar [In re EchoStar Communications Corp., 
    448 F.3d 1294
     (Fed. Cir. 2006)]:
    We recognize that the line between “factual”
    work product and “opinion” work product is
    not always distinct, especially when, as
    here, an attorney’s opinion may itself be
    “factual” work product. When faced with the
    distinction between where that line lies,
    however, a...court should balance the
    policies to prevent sword-and-shield
    litigation tactics with the policy to protect
    work product.

    The overarching goal of waiver in such a case
    is to prevent a party from using the advice
    he received as both a sword, by waiving
    privilege to favorable advice, and a shield,
    by asserting privilege to unfavorable advice.
    See Fort James Corp. [v. Solo Cup Co.], 412
    F.3d [1340] at 1349 [Fed. Cir. 2005]; [In re]
    Martin Marietta Corp., 856 F.2d [619] at 626
    [4th Cir. 1988]; In re Sealed Case, 
    676 F.2d 793
    , 818 (D.C. Cir. 1982) (“[W]hen a party
    seeks greater advantage from its control over
    work product than the law must provide to
    maintain a healthy adversary system[,] then
    the balance of interests recognized in
    - 19 -
    Hickman...shifts.”). To the extent the work-
    product immunity could have such an effect,
    it is waived.
    Id. at 1303.
    In Hartz Mountain Industries v. Commissioner, 93 T.C. at
    527, we summarized the waiver rules as follows:
    Protection derived from the work product doctrine
    is not absolute. United States v. Nobles, 
    422 U.S. 225
    , 239 (1975). Further, the work product doctrine,
    like the attorney-client privilege, may be waived.
    United States v. Nobles, 
    supra.
     Protection afforded by
    the work product doctrine to “opinion work product” may
    also be waived. See In re Sealed Case, 
    676 F.2d 793
    ,
    811 (D.C. Cir. 1982); Coleco Industries, Inc. v.
    Universal City Studios, 
    110 F.R.D. 688
    , 690-691
    (S.D.N.Y. 1986).
    In Hartz Mountain Industries and each of the three cited
    cases therein, the relevant court (1) concluded that the
    proponent of the privilege attempted to present a one-sided view
    of a critical matter in dispute and (2) refused to sustain the
    privilege in that setting.
    In Nobles, a defendant in a criminal case was not permitted
    to present testimony of an investigator unless the defendant
    turned over to the prosecution those portions of the
    investigator’s report that related to the investigator’s expected
    testimony.   When the defense called its investigator as a
    witness, the trial court ruled that the investigator’s report
    (after inspection and editing in camera) would have to be turned
    over to the prosecutor.   The defense stated that the report would
    not be turned over.   Whereupon the trial court ruled that the
    - 20 -
    investigator would not be permitted to testify.   United States v.
    Nobles, 
    422 U.S. 225
    , 229 (1975).   The Supreme Court held that
    the trial “court’s preclusion sanction was an entirely proper
    method of assuring compliance with its [disclosure] order.”     
    Id. at 241
    .
    In Hartz Mountain Industries v. Commissioner, 93 T.C. at
    528, we ruled as follows:
    Finally, petitioner has waived the work product
    doctrine by making a “testimonial use” of work product
    materials. See In re Sealed Case, 
    supra at 817-818
    ;
    Coleco Industries, Inc. v. Universal City Studios,
    supra at 691. Petitioner submitted affidavits from its
    in-house counsel to support its internal position with
    respect to the antitrust litigation. By offering this
    selective disclosure of work product to establish its
    intent, petitioner has waived all work product
    protection relevant to the same issue, and fairness
    requires discovery of all work product that pertains to
    petitioner’s antitrust settlement intentions. Coleco
    Industries, Inc. v. Universal City Studios, supra.
    Thus, although partial disclosure is not necessarily fatal to a
    claim of work product doctrine privilege, a “testimonial use” of
    the disclosed material may result in a conclusion that in
    fairness the related material must be disclosed even though it
    would otherwise be protected from disclosure.9
    9
    This has some similarity to Fed. R. Evid. 106, under which
    a party may interrupt another party’s presentation in order to
    require “the introduction at that time” of certain evidence
    “which ought in fairness to be considered contemporaneously with”
    the other party’s evidence.
    - 21 -
    In In re EchoStar Communications Corp., 
    448 F.3d 1294
     (Fed.
    Cir. 2006), defendants to a willful patent infringement suit
    asserted the defense of reliance on advice of counsel.     The Court
    of Appeals ruled:
    Work-product waiver extends only so far as to inform
    the court of the infringer’s state of mind. * * *
    The overarching goal of waiver in such a case is
    to prevent a party from using the advice he received as
    both a sword, by waiving privilege to favorable advice,
    and a shield, by asserting privilege to unfavorable
    advice.
    
    Id. at 1303
    .
    We note that, in response to petitioners’ section 7430
    motion, respondent refers to the two memoranda and respondent’s
    actions under section 6110 resulting in disclosure of the
    redacted Hyman memorandum.   As we view it, respondent’s
    references to the two memoranda are in the course of a recital of
    sequence of events.   The references are not by way of a
    contention that the existence of the two memoranda or the text of
    the redacted Hyman memorandum is evidence showing that
    respondent’s position was substantially justified, within the
    meaning of section 7430(c)(4)(B)(i).   Petitioners have not
    directed our attention to any attempt by respondent to make a
    “testimonial use” of either of the two memoranda (Hartz Mountain
    Industries v. Commissioner, 93 T.C. at 528), or to use either of
    the two memoranda as “a sword” (In re EchoStar Communications
    Corp., 
    448 F.3d at 1303
    ).
    - 22 -
    We conclude that respondent has not waived the work product
    doctrine privilege with respect to the Hyman memorandum.     We do
    not understand petitioners to contend that respondent waived the
    privilege with respect to the Welhaf memorandum, except as a
    derivative of their contention as to the Hyman memorandum.     We
    hold that the privilege has not been waived as to either
    memorandum.
    6.    Conclusion
    The unredacted memoranda are privileged from disclosure
    under the work product doctrine privilege.     Neither memorandum
    includes material such that the need to discover the work product
    is compelling.    Finally, respondent has not waived the protection
    of the work product doctrine privilege.
    An appropriate order will
    be issued denying petitioners’
    request to discover the unredacted
    memoranda.10
    10
    We note that the parties have stipulated the text of the
    redacted Hyman memorandum as a joint exhibit relating to
    petitioners’ secs. 7430 and 6673 motions. We have concluded that
    respondent’s references to the two memoranda in materials filed
    with the Court up to now do not constitute a use leading to
    waiver of the work product doctrine privilege.
