However, before discussing these changes, a brief overview of the Tax Court and its rules is helpful to provide context. Overview of the Tax Court and Its Rules The Tax Court is an Article I court that provides taxpayers with the ability to dispute a tax deficiency determination by the IRS before paying the disputed amount.4 The court’s jurisdiction extends to some disputes involving transferee liability, worker classification status, partnership items, innocent spouse relief, collection actions, whistleblower awards, interest abatement, administrative and litigation costs, and specific declaratory judgment actions. The ability to contest the IRS’s determination in a prepayment forum is a significant factor for most taxpayers and sometimes is the only option available, depending on the amount of the asserted tax deficiency and the taxpayer’s financial situation.

Introduction On July 6, 2012, the Tax Court adopted amendments to its Rules of Practice and Procedure (rules).1 The amendments were announced in proposed form on December 28, 2011; the final amendments reflect consideration of comments received from the IRS, the American Bar Association Section of Taxation, and the State Bar of Texas Section of Taxation.2 This article focuses on the amendments to Rule 70, which adopt the substantial need and undue hardship exception to the work product privilege and limit the discoverability of draft expert witness 1 See Tax Court release (July 6, 2012), Doc 2012-14486, 2012 TNT 133-51. Two weeks earlier, the Tax Court had announced a uniform method of citing pages in its memorandum opinions.

TAX NOTES, September 24, 2012 3 Other changes included: • changing the number of copies filed, font requirements, and return of papers (Rule 23); • deleting Rule 175 as obsolete; • making e-filing mandatory for most represented parties (Rule 26); • substituting the term ‘‘genuine dispute’’ for the term ‘‘genuine issue’’ as the summary judgment standard (Rule 121); • clarifying that Rule 155 also applies to dispositive orders (Rule 155); • enlarging the period for a tax matters partner to notify other partners of the filing of a petition (Rule 241); • increasing privacy protections for filings in whistleblower actions (Rule 345); • conforming amendments for number of copies (rules 241, 274, and 301), the redesignation of Rule 70(b)(2) (rules 71 and 74), and the recognition of unsworn written declarations (rules 20, 33, 57, 143, 173, 231, 232, 271, and 281); and • creating new Form 18 for unsworn declarations under penalty of perjury. 4 The Tax Court was established as an executive branch agency in 1924 as the Board of Tax Appeals (Revenue Act of 1924, ch. 234, section 900(k)). Its name was changed to the Tax Court of the United States in 1942, and its members became judges (Revenue Act of 1942, ch. 619, section 504(a)). Its name was changed to the United States Tax Court in 1969, when it also became a legislative court under Article I of the Constitution. Freytag v.

TAX PRACTICE COMMENTARY / TAX PRACTICE Under section 7453, the Tax Court is governed by the FRE. Its proceedings are conducted in accordance with the rules of evidence applicable to trials without a jury before the U.S. District Court for the District of Columbia, and therefore it applies the case law of the D.C. Circuit.7 However, under the authority granted in section 7453, the Tax Court has adopted its own rules8 and does not follow the FRCP. The court gives weight to the FRCP when there is no applicable rule.9 The Tax Court has characterized itself as being bound by evidentiary, but not procedural, rules in the FRCP.10 Absent an agreement by the parties regarding appellate venue, Tax Court decisions are appealable to the U.S. court of appeals for the circuit in which the taxpayer’s legal residence or, in the case of a corporation, principal place of business or office is located when the petition is filed.11 If no principal place of business or office exists when the petition is filed, appellate venue lies with the Court of Appeals for the District of Columbia.12 The Tax Court is a national court and therefore needs to maintain consistency in its opinions. However, it will defer to clear rulings on issues of law made by the court of appeals in the circuit in which an appeal would lie.13 Thus, although courts of appeals’ opinions 5 FRCP Rule 1; 28 U.S.C. section 2503(b). FRE Rule 101. 7 Rule 143(a). 8 The current version of the rules took effective January 1, 1974, and notes to the original rules are found at 60 T.C. 1057-1175 (1973). The rules have been amended several times over the years, with notes explaining each change published in the Tax Court report following the change. 9 See Brannon’s of Shawnee Inc. v. Commissioner, 69 T.C. 999, 1001 (1978); Rule 1(a). 10 See McKenzie v. Commissioner, 59 T.C. 139, 142-144 (1972), aff’d without published opinion, 486 F.2d 1401 (5th Cir. 1973); Bennett v.

Amendments to Work Product Protection The work product doctrine ‘‘shelters the mental processes of the attorney, providing a privileged area within which he can analyze and prepare his client’s case.’’14 The doctrine essentially shields communications and other materials prepared in anticipation of litigation. The work product doctrine protects the attorney’s patterns of investigation, determination of relevant facts, preparation of legal theories, planning of strategy, and recording of mental impressions.15 It also applies to information and materials prepared by a party’s representative other than an attorney or gathered by an agent acting under an attorney’s direction.16 Although the work product doctrine is distinct from the attorney-client privilege, the two can overlap. The existence of both privileges for the same documents can therefore be important if one privilege is waived but the other remains intact.17 The work product doctrine protects a broader range of materials, many of which are outside the confidential communications between attorney and client covered by the attorney-client privilege (for example, research memoranda, factual investigations, or notes from in-house strategy meetings).18 In Hickman v. Taylor, the Supreme Court acknowledged that the work product privilege is not absolute but found that the party seeking the production of fact-based work product materials could not overcome the privilege because the party failed to make ‘‘any showing of necessity or any indication 14 United States v. Noble, 422 U.S. 225, 238 (1975). In re Grand Jury Subpoena, 622 F.2d 933, 935 (6th Cir. 1980). 16 Diversified Indus. Inc. v. Meredith, 572 F.2d 596, 603 (8th Cir. 1977). 17 For example, most courts have held that the disclosure of otherwise privileged material to a taxpayer’s outside auditors waives the attorney-client privilege but not work product protection. See, e.g., United States v. Deloitte & Touche LLP USA, 610 F.3d 129, 139 (D.C. Cir. 2010), Doc 2010-14431, 2010 TNT 125-11 (collecting cases and discussing issues). FRE 502, ‘‘Attorney-Client Privilege and Work Product; Limitations on Waiver,’’ adopted in 2008, contains rules regarding the extent to which certain inadvertent disclosures can result in the waiver of the attorney-client privilege and work product protection. 18 In Hickman v. Taylor, 329 U.S. 495, 508 (1947), the Supreme Court explained that the attorney-client privilege ‘‘does not extend to information which an attorney secures from a witness while acting for his client in anticipation of litigation, . . . memoranda, briefs, communications and other writings prepared by counsel for his own use in prosecuting his client’s case, . . . [or] writings which reflect an attorney’s mental impressions, conclusions, opinions or legal theories.’’ However, it held that all of these matters were protected by the work product doctrine.

The other options for judicial review are refund actions. The taxpayer must pay the tax deficiency, then file a refund claim, and when the IRS denies the claim or six months have elapsed, file suit for a refund in the U.S. district court where the taxpayer resides or in the U.S. Court of Federal Claims. District court proceedings are governed by the FRCP, and Court of Federal Claims proceedings are governed by the Rules of the United States Court of Federal Claims, which incorporate the FRCP to the extent appropriate for proceedings in that court.5 Both courts are governed by the Federal Rules of Evidence (FRE).6 COMMENTARY / TAX PRACTICE Before the recent Tax Court amendments, Rule 70 contained no specific provisions for the disclosure of otherwise protected work product on a showing of substantial need and undue hardship. The Tax Court pointedly did not adopt that exception in the FRCP, as reflected in the statement in the initial notes to Rule 70 that ‘‘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 [Rule] 26(b)(3) have not been adopted.’’23 Shortly after adopting Rule 70, the Tax Court took particular note of the ‘‘negative recognition’’ given the work product doctrine in its rules and notes.24 Later, the Tax Court flatly stated 19 Id. at 509. FRCP Rule 26(b)(3)(B). 21 Upjohn Co. v. United States, 449 U.S. 383, 400-402 (1981). 22 See, e.g., In re Cendant Corp. Sec. Litig., 343 F.3d 658, 663 (3d Cir. 2003); In re Murphy, 560 F.2d 326, 336 (8th Cir. 1977); but see Duplan Corp. v. Moulinage et Retorderie de Chavanoz, 509 F.2d 730, 734 (4th Cir. 1974) (opinion work product never discoverable). For example, the Ninth Circuit has indicated that opinion work product may be discovered ‘‘when mental impressions are at issue in a case and the need for the materials is compelling.’’ Holmgren v. State Farm. Mut. Auto. Ins. Co., 976 F.2d 573, 577 (9th Cir. 1992) (emphasis in original); see also Ratke v. Commissioner, 129 T.C. 45, 53 (2007) (discussing law of the Ninth Circuit). 23 60 T.C. at 1098 (emphasis added). 24 P.T.&L. Const. Co. v. Commissioner, 63 T.C. 404, 408 (1974); see also Dvorak v. Commissioner, 64 T.C. 846, 850-851 (1975) (refusing to ‘‘incorporate into this Court’s discovery procedure the requirements of rule 26(b)(3) of the [FRCP], under which ‘work product’ materials are discoverable if ‘the substantial equivalent of the materials’ is unavailable’’). 20 TAX NOTES, September 24, 2012 that ‘‘under the Tax Court Rules, the work product of counsel is not discoverable.’’25 Over the years, several Tax Court opinions have chipped away at the absolute protection for work product reflected in the notes and prior opinions. These opinions suggested that the privilege resulting from the work product doctrine might be qualified in the Tax Court, as in other courts, allowing it to be overcome by an appropriate showing of substantial need and undue hardship. For example, in Hartz Mountain, the court stated that ‘‘The use of the word ‘generally’ in the note to Rule 70 strongly suggests that the scriveners recognized that the refusal to incorporate FRCP [Rule] 26(b)(3) was limited to the purview of that rule and did not constitute a bar to production of all work product.’’26 In Ames the court noted, without any reference to its rules, the accompanying notes or prior Tax Court precedent that ‘‘The work product privilege is a qualified one that, in some circumstances, may be overcome by a showing of good cause and substantial need.’’27 However, because the court found that the materials at issue were opinion work product, it did not analyze the substantial need and undue hardship exception. In Ratke, the taxpayer argued that the IRS was required to produce IRS memoranda seeking advice concerning proposed legal arguments to be made in the case.28 The issue was whether the memoranda were work product and, if so, whether they should nevertheless be disclosed. The court determined that the memoranda were fact-based and opinion work product. Thus, it was necessary for the court to determine whether the substantial need and undue hardship exception required disclosure of the privileged materials. The court began by acknowledging the ‘‘negative recognition’’ provided in the notes and its prior holding in P.T.&L. Construction, but nevertheless it proceeded to examine the extent of the privilege.29 Citing Hartz Mountain and Ames, the Tax Court held that ‘‘The privilege resulting from the work product doctrine is qualified; it may be overcome by an appropriate showing.’’30 After reviewing the memoranda, the court concluded that: (1) the substantial need and undue hardship exception did not apply to the fact-based 25 Zaentz v. Commissioner, 73 T.C. 469, 478 (1979). Hartz Mountain Indus. v. Commissioner, 93 T.C. 521, 529 (1989). 27 Ames v.

Documents and Tangible Things: A. A party generally may not discover documents and tangible things that are prepared in anticipation of litigation or for trial by or for another party or its 31 Id. at 54. As discussed in supra note 22, the Tax Court looked to case law of the Ninth Circuit, the circuit to which the case was appealable. In doing so, it noted that the Supreme Court has ‘‘declined to decide whether opinion work product is absolutely protected from discovery.’’ Id. at 53. 32 Sterling Trading Opportunities LLC v. Commissioner, T.C. Memo. 2007-339, Doc 2007-25408, 2007 TNT 221-14. 33 Id. at *6. 1594 representative (including the other party’s attorney, consultant, surety, indemnitor, insurer, or agent), unless, subject to Rule 70(c)(4), i. they are otherwise discoverable under Rule 70(b); and ii. the party shows that it has substantial need for the materials to prepare its case and cannot, without undue hardship, obtain their substantial equivalent by other means. B. If the Court orders discovery of those materials, it must protect against disclosure of mental impressions, conclusions, opinions, or legal theories of a party’s counsel or other representative concerning the litigation. The Tax Court acknowledged the negative recognition in its notes regarding the substantial need and undue hardship exception, but it indicated that the change was made ‘‘to formalize the Court’s application of the work product doctrine, set forth in [FRCP Rule] 26(b)(3).’’ Citing Ratke, the notes explain that the new language was ‘‘drawn from rule 26(b)(3)(A) and (B) of the [FRCP] and includes the exception to the work product privilege provided upon a showing of substantial need for the materials sought to be discovered.’’ Limitations on Discovery Regarding Experts In the Tax Court, an expert witness’s report is treated as his direct testimony, and additional direct testimony may be allowed ‘‘to clarify or emphasize matters in the report, to cover matters arising after the preparation of the report, or otherwise at the discretion of the Court.’’34 The report must contain the qualifications of the expert witness and shall state the witness’s opinion and the facts or data on which the opinion is based and must ‘‘set forth in detail the reasons for the conclusion.’’35 The parties are required to exchange copies of any expert witness reports expected to be submitted into evidence at trial. As adopted, the Tax Court’s rules did not contain a limitation on the discovery of drafts of an expert witness’s report. In 2010 FRCP Rule 26(b)(4) was amended to provide that drafts of expert witness reports and certain pretrial communications between experts and counsel were not subject to discovery. In the recent amendments to its rules, the 34 Rule 143(g)(2). Rule 143(g)(1). 35 TAX NOTES, September 24, 2012 (C) Tax Analysts 2012. All rights reserved. Tax Analysts does not claim copyright in any public domain or third party content. work product; and (2) there was no ‘‘compelling need’’ for the opinion work product.31 Approximately two months after its opinion in Ratke, the Tax Court addressed whether documents containing notes by an individual and his attorney made during meetings with tax advisers were work product subject to discovery under the exception.32 The court assumed, without deciding, that the documents contained fact-based work product. Relying on Ratke, it framed the remaining question as whether the IRS had substantial need for the information in the documents and the inability to obtain the substantial equivalent from other sources. The court accepted the IRS’s claimed substantial need to show the purpose, structure, parties, and fees for a transaction that was purportedly entered into for purely tax avoidance reasons. This acceptance appeared to be based primarily on the taxpayer’s failure to argue that the IRS lacked a substantial need for the information in the document, rather than on an affirmative showing of need by the IRS. Regarding the inability to obtain the substantial equivalent, the court found that the IRS’s unsuccessful efforts to obtain information about the meetings — from depositions and interviews of individuals who purportedly attended the meetings based on the lapse of time and faded memories — demonstrated that there was no other way for the IRS to obtain the information in the documents. It therefore concluded that the IRS had made an adequate showing of ‘‘substantial need for the information contained in the two documents and the inability to obtain the substantial equivalent from other sources’’ to overcome the work product privilege.33 The recent amendment to Rule 70 cleared up any remaining doubt on the subject, as the Tax Court officially adopted the application of the work product doctrine set forth in FRCP Rule 26(b)(3). The amendment added a new paragraph (c)(3) under Rule 70, which closely tracks FRCP Rule 26(b)(3)(A) and (B): COMMENTARY / TAX PRACTICE proaches to the issues on which they are testifying, whether or not the expert considered them in forming the opinions expressed. These discovery changes therefore do not affect the gatekeeping functions called for by Daubert v. Merrell Dow Pharmaceuticals Inc., 509 U.S. 579 (1993), and related cases.’’39 Thus, the opposing party has the opportunity at trial to question the expert witness about the formulation of his report if there are any ghostwriting concerns. The IRS suggested that the Tax Court provide the same substantial need and undue hardship exception for protected expert reports and attorneyexpert communications. Ultimately, the court did not adopt the IRS’s approach. On September 13, 2012, the Office of Chief Counsel issued Notice CC-2012-016 regarding the rule amendments. After reiterating its original opposition to Rule 70(c)(4) and ‘‘the potential for undue attorney influence in the drafting of reports,’’ Chief Counsel advised attorneys that the rule ‘‘does not prohibit a party from questioning experts at trial on the same information and communications that are protected in discovery. For instance, when appropriate, counsel may cross examine or voir dire an opposing expert witness in depth on any revisions the opposing party’s counsel suggested to the offered expert report.’’ This position is inconsistent with FRCP Rule 26(b)(4)(C), which permits crossexamination regarding alternative analyses, testing methods, and approaches to issues on which the expert is testifying, but protects trial preparation materials. Accordingly, if the IRS is prohibited from asking for attorney-expert communications in discovery, it cannot ask for that same protected information simply because it is in the context of crossexamination at trial. Impact of Amendments The Tax Court’s rule changes are significant, both for taxpayers considering the appropriate forum in which to litigate their cases and for taxpayers with cases already docketed in the Tax Court. Tax Court precedent and the ability to contest the IRS’s determination in a prepayment forum are generally viewed as the most important factors weighing in favor of litigating a case in the Tax Court. Some have viewed the absolute protection afforded all work product materials that was espoused in early Tax Court cases such as P.T.&L. Construction and Zaentz as a factor weighing in favor of litigating a case in the Tax Court.40 To the 39 36 Advisory committee’s note to FRCP Rule 26 (2010). 37 Id. 38 Advisory committee note’s to FRCP Rule 26(b)(4) (2010).

TAX NOTES, September 24, 2012 1595 (C) Tax Analysts 2012. All rights reserved. Tax Analysts does not claim copyright in any public domain or third party content. Tax Court amended Rule 70 to provide the same discovery protection in its proceedings. Rule 70(c)(4) now provides: 4. Experts: A. Rule 70(c)(3) protects drafts of any expert witness report required under Rule 143(g), regardless of the form in which the draft is recorded. B. Rule 70(c)(3) protects communications between a party’s counsel and any witness required to provide a report under Rule 143(g), regardless of the form of the communications, except to the extent the communications: i. relate to compensation for the expert’s study or testimony; ii. identify facts or data that the party’s counsel provided and that the expert considered in forming the opinions to be expressed; or iii. identify assumptions that the party’s counsel provided and that the expert relied on in forming the opinions to be expressed. Limiting discovery for draft expert witness reports was intended to counteract ‘‘undesirable effects’’ stemming from courts routinely allowing discovery of all draft reports.36 These effects included rising costs, impediments to effective communication and interaction between counsel and experts, and the adoption of strategies by experts to protect against discovery that interfered with their work.37 The limitations were also ‘‘designed to protect counsel’s work product and ensure that lawyers may interact with retained experts without fear of exposing those communications to searching discovery.’’38 In comments on the proposed amendment, the IRS expressed several concerns with this change. The thrust of those concerns was that foreclosing the opportunity to explore reports through discovery would prevent parties from identifying whether any ghostwriting was occurring. However, in the Tax Court an expert’s report is treated as his direct testimony and it must convey completely and clearly the expert’s conclusions because the proponent typically will not be able to ask the expert to expand on the opinion. Moreover, as the advisory committee’s note to FRCP Rule 26(b)(4) recognizes, ‘‘Counsel are also free to question expert witnesses about alternative analyses, testing methods, or ap- COMMENTARY / TAX PRACTICE cited Golsen and followed case law of the Second Circuit in applying the federal common law of privilege.42 In Bernardo, appealable to the First Circuit, the Tax Court cited section 7453 and followed D.C. Circuit precedent in determining whether some documents were protected by the attorneyclient privilege and not subject to disclosure.43 In its analysis of whether the same documents were protected work product, the court did not cite section 7453 but did rely on D.C. Circuit precedent for the proper standard to apply in determining whether the documents were prepared in anticipation of litigation. The question of which law to apply is significant in other areas as well — for example, the high-profile disputes in recent years over the discoverability of tax accrual workpapers.44 In view of this uncertainty, taxpayers and their advisers must make sure that they are familiar with case law under both the D.C. Circuit and the circuit in which an appeal would normally lie. The limitation on the discoverability of drafts of expert reports and communications between experts and counsel should be viewed as a welcome development for many practitioners. Counsel and an expert often must work together to make sure that the expert’s report appropriately addresses the issues on which the expert is providing his opinion. The ability to do so without fear of ghostwriting allegations may promote more precise and helpful reports. Parties are always free to cross-examine experts regarding the preparation of reports, which ultimately might be a more efficient and practical forum to raise any concerns regarding whether the expert or counsel drafted the report. 42 Director v.

Thus, in cases when fact-based work product materials contain particularly sensitive information that could dramatically affect the proceedings, the IRS may be able to obtain this information if the agency is able to show the requisite substantial need and undue hardship. Further, based on the adoption of the same work product rules as in FRCP Rule 26(b)(3), it appears that even opinion work product may be subject to discovery if a party makes a showing beyond the substantial need and undue hardship test required for fact-based work product. The new standard for work product may result in more litigation in the Tax Court. Parties may now be able to obtain previously protected materials after making the requisite showing. And parties may engage in more disputes over the discoverability of both fact-based and opinion work product, now that it is clear no absolute protection exists. As discussed above, the Tax Court looks to the case law of the D.C. Circuit to resolve evidentiary matters, and under the Golsen rule, the Tax Court is bound to apply the law of the circuit in which an appeal would normally lie. It is unclear whether the Tax Court will decide disputes over work product by looking to the case law of the D.C. Circuit or the circuit in which an appeal would normally lie. A few cases on this subject indicate that there is no clear answer. In Ratke, the Tax Court discussed opinion work product precedent from the Ninth Circuit, to which the case was appealable.41 In an earlier memorandum opinion, the court referenced section 7453 and Rule 143(a) at the beginning of its analysis of whether grand jury materials were privileged but
