Tax'Analysts, a nonprofit District of Columbia corporation, brought an action under the Freedom of Information Act (“FOIA”), 5 U.S.C. § 552, to compel the Internal Revenue Service to disclose certain documents known as “Field Service Advice Memoran-da.” The district court issued an order requiring disclosure after redaction. The IRS appeals on the grounds that the court misconstrued FOIA § 552(a)(2)(B), and that the records were protected by FOIA exemptions 3 and 5.
I
Field Service Advice Memoranda, known by their initials “FSAs,” are issued by the Office of Chief Counsel for the IRS. The Office of Chief Counsel employs more than 1600 attorneys and provides legal advice to the IRS, directs litigation in the Tax Court, and provides guidance and support for litigation in other courts. See INTERNAL Revenue Manual 1171 (1993). Although the Chief Counsel is the chief legal officer for the IRS, id, the Office of Chief Counsel is not part of the IRS. The Chief Counsel is an Assistant General Counsel of the Treasury Department, appointed by the President with the advice and consent of the Senate. 31 U.S.C. § 301(f)(2). For most purposes, the Chief Counsel is subject to the supervision of the General Counsel of the Treasury Department, not the Commissioner of Internal Revenue (although during the time period relevant to this case, the Commissioner delegated certain IRS functions, including handling agency appeals, to the Office of Chief Counsel, and the Commissioner retained authority over the Office *609 of Chief Counsel with respect to those functions). Internal Revenue Manual 1112.62 (1990). According to the deposition testimony of senior officials in the Office of Chief Counsel, that office understands itself as independent from the IRS.
Attorneys in the national office of the Office of Chief Counsel prepare FSAs in response to requests from field personnel of either the Office of Chief Counsel or the IRS, such as field attorneys, revenue agents, and appeals officers. Field personnel request an FSA for legal guidance, usually with reference to the situation of a specific taxpayer. Each FSA includes a statement of issues, a conclusions section, a statement of facts, and a legal analysis section. Chief Counsel Directives Manual (35)(19)44 (1992). 1 The staff preparing an FSA are instructed that the conclusions section should recommend a position on each issue and state “any limitations or conditions to which a conclusion may be subject.” Id. The style of the analysis section “should be exploratory and descriptive so that the strengths and weaknesses of a case are presented and developed candidly, directing attention to the authorities against the conclusions arrived át as well as those which support them.” Id.
The government agrees that among the primary purposes of FSAs is ensuring that field personnel apply the law correctly and uniformly. The IRS tells us that FSAs are not formally binding on IRS field personnel who request them. It is not clear whether they bind requesters within the Office of Chief Counsel. In any case, the government concedes that FSAs are held in high regard and are generally followed.
Treasury Department regulations treat the Office of Chief Counsel as part of the IRS for purposes of FOIA requests. 31 C.F.R. § 1.1. Accordingly, Tax Analysts directed its requests for FSAs to the IRS, not the Office of Chief Counsel. Although Tax Analysts originally asked for both formal written FSAs and written records of advice provided informally to field personnel by telephone, Tax Analysts has since limited its claims to the approximately 1300 formal written FSAs issued by the Office of Chief Counsel between January 1. 1992, and December 14, 1993. The IRS failed to respond to Tax Analysts’s initial requests within the statutory time period. Tax Analysts pursued unsuccessful administrative appeals and then filed suit in district court. The parties conducted extensive discovery, and both moved for summary judgment. The district court granted Tax Analysts’s motion and later awarded it attorney’s fees. 2
II
A remedial question needs to be addressed before we proceed any further. Throughout this litigation, Tax Analysts claimed that FSAs fall under the FOIA section requiring “[e]ach agency ... [to] make available for public inspection and copying ... those statements of policy and interpretations which have been adopted by the agency and are not published in the Federal Register.” 5 U.S.C. § 552(a)(2)(B). 3 This is the so-called “reading room” provision.
The district court’s memorandum opinion agreed that FSAs fell within § 552(a)(2)(B).
*610
But rather than explicitly requiring the IRS to make these documents available in a reading room, the court’s order directed the IRS to “release all requested” FSAs, except to the extent that certain statutory exemptions apply. The IRS takes this to mean that it is obligated only to produce the FSAs to Tax Analysts. Any broader relief, the IRS claims, would be beyond the court’s authority in light of our opinion in
Kennecott Utah Copper Corp. v. Department of the Interior,
Tax Analysts has offered nothing in opposition to the IRS’s argument regarding the limited scope of the remedy and it has not cross-appealed from the district court’s order. We will, therefore, treat the argument as conceded for the purposes of this case only. This considerably simplifies matters. With the case in this posture there is no need for us to decide whether FSAs are “statements of policy and interpretations which have been adopted by the agency” under § 552(a)(2)(B). If § 552(a)(2)(B) did not require FSAs to be “made available for public inspection,” another FOIA provision— § 552(a)(3) — required them to be made available to Tax Analysts, unless the documents were exempt from disclosure. Section 552(a)(3), which Tax Analysts invoked in its initial FOIA requests to the IRS, provides that: “Except with respect to records made available under paragraphs (1) and (2) of this subsection, each agency, upon any request for records which (A) reasonably describes such records and (B) is made in accordance with published rules ... shall make the records promptly available to any person.” There is, we believe, no doubt that the requests here “reasonably deseribe[d]” the FSAs. “A request reasonably describes records if ‘the agency is able to determine precisely what records are being requested.’”
Kowalczyk v. Department of Justice,
Ill
FSAs constitute agency “records” within 5 U.S.C. § 552(a)(3): the Office of Chief Counsel created the documents and retained control over them.
See Department of Justice v. Tax Analysts,
The government invokes FOIA exemptions 3 and 5. FSAs fall under exemption 3, it says, because these are “matters” “specifically exempted from disclosure by statute,” 5 U.S.C. § 552(b)(3). FSAs also are allegedly protected by exemption 5, which empowers an agency to withhold “inter-agency or intra-agency memorandums or letters which would not be available by law to a party other than *611 an agency in litigation with the agency,” 5 U.S.C. § 552(b)(5).
A. Exemption 3
The government rests its exemption 3 claim on 26 U.S.C. § 6103. Amended in 1976 in the wake of Watergate and White House efforts to harass those on its “enemies list,” § 6103 now restricts government officers and employees from revealing “any return” or “return information.” “Return information” is defined as:
a taxpayer’s identity, the nature, source, or amount of his income, payments, receipts, deductions, exemptions, credits, assets, liabilities, net worth, tax liability, tax withheld, deficiencies, overassessments, or tax payments, whether the taxpayer’s return was, is being, or will be examined or subject to other investigation or processing, or any other data, received by, recorded by, prepared by, furnished to, or collected by the Secretary with respect to a return or with respect to the determination of the existence, or possible existence, of liability (or the amount thereof) of any person under this title for any tax, penalty, interest, fine, or other imposition, or offense....
26 U.S.C. § 6103(b)(2)(A). This definitional provision continues by excluding from the category of return information “data in a form which cannot be associated with, or otherwise identify, directly or indirectly, a particular taxpayer.”
5
Passed as a floor amendment to § 6103(b)(2), the clause just quoted — the Haskell Amendment — became the subject of the Supreme Court’s opinion in
Church of Scientology of California v. IRS,
That § 6103 is the sort
of
nondisclosure statute contemplated by FOIA exemption 3 is beyond dispute. To paraphrase exemption 3, § 6103 is a statute specifically exempting certain matters from disclosure to the general public and leaving the IRS with no discretion to reveal those matters publicly. Our decision in
Church of Scientology of California v. IRS,
The district court’s reasoning in support of this conclusion does not survive close attention. The court treated
Taxation With Representation Fund v. IRS,
To the district court here,
TWRF
supported these conclusions: (1) “in legally relevant aspects, FSAs are akin to GCMs and TMs”; and (2) since GCMs and TMs are not § 6103(b)(2) “return information” in their entirety, then neither are FSAs. The second proposition, critical in the court’s analysis, does not follow from
TWRF.
Our
TWRF
opinion decided nothing about § 6103. True enough, the
TWRF
district court ordered the IRS to delete “return information” from the GCMs and TMs. But it never explained why, and it never specified what comprised return information. Nothing can be made of the IRS’s determination not to appeal the redaction order. The government does not appeal every judicial order with which it disagrees. And it has no duty to do so. Its failure to appeal the
TWRF
order therefore cannot be seen as some sort of admission about § 6103’s meaning. An appeal would have been futile anyway, which may explain why one was not taken. While
TWRF
was making its way through this circuit, a now-repudiated interpretation of the Haskell Amendment prevailed. Return information, we then believed, meant “only information that directly or indirectly identifies a particular taxpayer”; redaction of such information, we thought, removed § 6103’s protection against disclosure.
See Neufeld v. IRS,
We are therefore back to square one: Are the legal interpretations and analyses contained in the FSAs “any other data, received by, recorded by, prepared by, furnished to, or collected, by the Secretary with respect to a return or with respect to the determination of the existence, or possible existence, of liability (or the amount thereof) of any person under this title for any tax, penalty, interest, fine, or other imposition, or offense,” 26 U.S.C. § 6103(b)(2)(A)? If these portions of the FSAs are within the catchall “other data,” the Supreme Court’s
Scientology
opinion makes it irrelevant whether the legal analyses and conclusions themselves identify any individual taxpayers.
Church of Scientology,
As to § 6103(b)(2)(A)’s catchall clause, we know that FSAs, and the legal analyses in them, are “prepared by ... the Secretary with respect to a return or with respect to the determination of the existence, or possi *613 ble existence, of liability (or the amount thereof) of any person under this title for any tax, penalty, interest, fine, or other imposition, or offense.” But are legal interpretations of statutes, rules, regulations, and judicial opinions, and the legal conclusions flowing from those interpretations “data”? Tax Analysts says no, “data” means only facts and it is only facts that § 6103 protects, facts such as the taxpayer’s identity, or income, or deductions, or the existence of an IRS audit or a criminal investigation. Cases from other circuits dealing with § 6103(b)(2) do not help either side. 7 Nor does the dictionary. Nor does legislative history. But principles of administrative law tilt in favor of the IRS’s position.
The principles are the familiar ones, set down in
Chevron U.S.A. Inc. v. Natural Resources Defense Council, Inc.,
Of course,
Chevron
deference assumes that the agency has adopted an interpretation of the statute and that the court knows what that interpretation is. In this case, we have the letters of the Assistant Chief Counsel denying Tax Analysts’s FOIA administrative appeals partly on the ground that the FSAs constituted § 6103(b) “return information” “in their entirety.” The letters are eoncluso-ry. They do not say how the Chief Counsel construes the term “data” in § 6103(b)(2), or why. The IRS’s brief in this court is a bit more enlightening. It argues that “data” includes legal conclusions and analyses as well as facts, indeed includes everything “generated by the IRS with respect to the liability of a taxpayer.” One might consider the interpretation of § 6103 reflected in the IRS’s argument to be merely a litigating position. But that would not necessarily preclude our deferring to the agency’s interpretation so long as it represented the IRS’s “fair and considered judgment on the matter,”
Auer v. Robbins,
— U.S. -, -,
We therefore move on to the first inquiry in the
Chevron
analysis-r-namely, “whether Congress has directly spoken to the precise question at issue,”
Chevron,
Still, there is something to the
ejusdem generis
point. Each of the specific items mentioned in the beginning of § 6103(b)(2)(A) is not only factual but unique to the particular taxpayer. And each of the more general items in § 6103(b)(2)(A) — “any other data, received by, recorded by, prepared by, furnished to, or collected by the Secretary with respect to a return” or the liability “of any person” — is of the same character, that is, unique to a particular taxpayer. The IRS has itself drawn this very distinction in propounding its view of what constitutes return information. FSAs relating to “groups or classes of taxpayers” rather than to a particular taxpayer, the IRS concedes, “do not constitute return information protected by Exemption 3.” Yet legal analyses and conclusions also cannot be viewed as unique to a particular taxpayer, or as the IRS puts it, “taxpayer-specific.” If the Office of Chief Counsel renders an interpretation of a certain section in the tax code, whether in an FSA or elsewhere, that interpretation should apply to all other taxpayers who are, in material respects, similarly situated. Treating like cases alike is, we have said, “the most basic principle of jurisprudence.”
La-Shawn A. v. Barry,
On other hand, we cannot say that the term “data” is incapable of bearing the meaning the IRS ascribes to it. For evidence that “data” might encompass not only facts but law, one need look no further than Supreme Court opinions. In
Standard Oil Co. v. Johnson,
While “data” therefore might signify even legal discussions, we are hard pressed to find any reason derived from § 6103 in favor of the IRS’s interpretation. The IRS has offered none. It simply slaps § 6103 on the table and tells us that everything in an FSA, every line, every word, is immune from disclosure. If the FSA recites material from census reports or statistics relating to an industry or quotes statutes or regulations, all of this would be “return information.” Why § 6103 should protect such non-taxpayer-specific information is a mystery the IRS has not offered to solve. This is not to suggest that the IRS has no reason for wanting to keep the FSAs secret. It has argued, in the context of another FOIA exemption, that revealing the law sections of these records would be disruptive to its enforcement efforts and might discourage those in the field from seeking national office advice. Whatever the merits of these IRS concerns, they have nothing to do with § 6103’s core purpose of protecting taxpayer privacy.
See Church of Scientology,
Furthermore, in interpreting § 6103 and in evaluating whether the IRS interpretation of “data” would be a permissible one if the term were ambiguous in the context of § 6103(b)(2)(A), we must look not only at that section but at related provisions in the statute.
National R.R. Passenger Corp. v. Boston & Maine Corp.,
The regulations define “Technical Advice Memorandum” as:
a written statement issued by the National Office to, and adopted by, a district director in connection with the examination of a taxpayer’s return or consideration of a taxpayer’s claim for refund or credit. A technical advice memorandum generally recites the relevant facts, sets forth the ■applicable law, and states a legal conclusion.
26 C.F.R. § 301.6110-2(f). An IRS Revenue Procedure explains in more detail what the agency considers to be a Technical Advice Memorandum:
“Technical advice” means advice or guidance in the form of a memorandum fur: nished by the national office [of the Office of Chief Counsel] upon the request of a district director or a chief, appeals office, submitted in accordance with the provisions of this revenue procedure, in response to any technical or procedural question that develops during any proceeding on the interpretation and proper application of tax law, tax treaties, regulations, revenue rulings, notices, or other precedents published by the national office to a specific set of facts. Such proceedings include: (1) the examination of a taxpayer’s return; (2) the consideration of a taxpayer’s claim for refund or credit; (3) any matter under examination or in appeals pertaining to tax-exempt bonds or mortgage credit certificates; and (4) any other matter involving a specific taxpayer under the jurisdiction of the chief, examination division, or the chief, appeals office....
Technical advice helps Internal Revenue Service personnel close cases and also helps establish and maintain consistent holdings throughout the Service.
*616
Rev. Proc. 97-2, 1997-
We see no difference, relevant to § 6103, between FSAs and Technical Advice Memo-randa. Both are means by which the national office of the Office of Chief Counsel provides field offices with advice about the tax laws in response to questions regarding specific factual situations. FSAs and Technical Advice Memoranda serve similar purposes and the outline they follow is basically the same. This is not to suggest that FSAs and Technical Advice Memoranda are identical. The Office of Chief Counsel’s internal guidance. points out the following distinctions: taxpayers are always permitted to participate in the technical advice process, while taxpayer participation in the FSA process is left to the discretion of field personnel; Technical Advice Memoranda, but not FSAs, are “final determinations” of the IRS’s position; FSAs, unlike Technical Advice Memoranda, are not publicly released under FOIA or § 6110, are not widely distributed within the IRS or the Office of Chief Counsel, and are not disclosed to taxpayers. Chief Counsel Directives Manual (35)274 (1996). Field personnel are instructed that “[t]he choice of whether to request Field Service Advice or Technical Advice depends on whether the advice is intended to establish the position of the Service in a specific case with respect to the issue presented.” Id. None of these distinctions, however, has anything to do with the taxpayer privacy concerns underlying § 6103. With respect to the purposes of § 6103, Technical Advice Memoranda and FSAs amount to the same thing.
Congress did not mention FSAs in § 6110, but that is entirely understandable. FSAs did not exist in their present form until 1991, fifteen years after § 6110 became law. The provision nevertheless is significant. Only a Janus-faced Congress would, in § 6110, order the IRS to disclose the legal analysis portion of a Technical Advice Memorandum and then, in § 6103, order the IRS not to disclose the same portion of an FSA. The IRS’s position, rather than bringing § 6103(b)(2)(A) into harmony with the rest of the Internal Revenue Code, would create an anomaly within the Code’s disclosure system.
While the IRS’s interpretation of “data” in § 6103(b)(2)(A) may be linguistically possible, we therefore conclude that it is not a permissible construction of the statute in light of its structure and purposes. Legal analyses contained in FSAs are not “return information” under § 6103, and the IRS’s exemption 3 claim fails.
B. Exemption 5
Exemption 5 permits an agency to withhold materials normally privileged from discovery in civil litigation against the agency.
NLRB v. Sears, Roebuck & Co.,
1. Deliberative Process Privilege
The deliberative process privilege, a variant of executive privilege, shields only government “materials which are both predecisional and deliberative.”
Wolfe v. Department of Health & Human Servs.,
*617
“A strong theme of our [deliberative process] opinions has been that an agency will not be permitted to develop a body of ‘secret law5....”
Coastal States,
Rather than documents produced in the process of formulating policy, FSAs are themselves statements of an agency’s legal position and, as such, cannot be viewed as predecisional.
See Coastal States,
Exemption 5, and the deliberative process privilege, reflect the legislative judgment that “the quality of administrative decisiom making would be seriously undermined if agencies were forced to ‘operate in a fishbowl’ because the full and frank exchange of ideas on legal or policy matters would be impossible.”
Mead Data Cent., Inc. v. Department of the Air Force,
The government points out that in addition to the protection of agency decision making, we have also identified as purposes of the deliberative process privilege “protection] against premature disclosure of proposed policies” and “protection] against confusing the issues and misleading the public by dissemination of documents suggesting reasons and rationales for a course of action which were not in fact the ultimate reasons for the agency’s action,”
Coastal States,
2. Attorney-Client Privilege
The attorney-client privilege protects confidential communications from clients to their attorneys made for the purpose of securing legal advice or services.
In re Sealed Case,
In light of our decision about exemption 3, the issue here is not whether the IRS must disclose taxpayer-specific information. Wholly aside from the attorney-client privilege, such information must be redacted from FSAs because it is “return information” protected by § 6103. As to application of the privilege to the remaining portions of the FSAs relating to individual taxpayers and to the approximately 112 FSAs relating to classes of taxpayers,
see supra
note 6, our decisions in
Schlefer v. United States,
*619
Schlefer
dealt with documents containing legal advice from an agency’s chief counsel to agency officials. The officials sought legal guidance to assist them' in ruling on requests from “outsiders.”
Coastal States
leads to the same conclusion. We there held that when agency auditors communicate information from third parties to the agency’s regional counsel and ask for legal advice, the regional counsel’s written responses containing “neutral, objective analyses of agency regulations” are not privileged.
The IRS suggests that some FSAs may reveal confidential information transmitted *620 by field personnel regarding “the scope, direction, or emphasis of audit activity.” Communications revealing such client confidences are in a different category than those we have been discussing. They are clearly covered by the attorney-client privilege, and the IRS may still assert the privilege with respect to particular portions of FSAs containing this sort of confidential government information.
3. Work Product Doctrine
The work product doctrine shields materials “prepared in anticipation of litigation or for trial by or for [a] party or by or for that ... party’s representative (including the ... party’s attorney, consultant, ... or agent).” Fed.R.Civ.P. 26(b)(3);
see also Hickman v. Taylor,
IV
We agree with the district court that no blanket exemption applies to all of the requested FSAs, and they must be released to Tax Analysts except to the extent that they are protected by some specific FOIA exemption. As the district court ordered, the IRS may redact any true return information or attorney work product from the FSAs.
Other grounds for withholding certain FSAs or portions of FSAs may also apply. The IRS may redact matters that are properly within the scope of the attorney-client privilege consistent with what we said above. The IRS claims that portions of 32 of the FSAs fall under exemption 3 due to secrecy clauses in tax treaties and tax information exchange agreements. It says that portions of 206 of the FSAs are protected by exemption 7(E), which applies to materials that “would disclose techniques and procedures for law enforcement investigations or prosecutions, or would disclose guidelines for law enforcement investigations or prosecutions if such disclosure could reasonably be expected to risk circumvention of the law,” 5 U.S.C. § 552(b)(7)(E). And it contends that one FSA falls under exemption 6, which shields “personnel and medical files and similar files the disclosure of which would constitute a clearly unwarranted invasion of personal privacy,” id. § 552(b)(6). The district court did not pass on these claims, and Tax Analysts raises some doubt about whether the government properly presented them. We remand the ease to the district court so it may consider these issues.
So ordered.
Appendix
(See supra note 1.)
ADDITIONS TO TAX, PENALTIES, APPLICATION OF NEGLIGENCE TO CAR- *621 RYBACK YEARS: The addition to tax under I.R.C. § 6658(a)(2) may not be asserted on the basis of an NOL carryback in a tax year for which the tax is due prior to December 31,1981.
From 1954 until 1982, the addition to tax under I.R.C. § 6653(a) applied where any part of an underpayment was due to negligence. Section 6653 was amended by the Economic Recovery Tax Act of 1981 (ERTA), Pub.L. No. 34, HR 4242, 97th Cong., 1st Sess. The effective rate of the addition was increased by adding to it an amount equal to 50 percent of the interest on the negligence-tainted portion of the deficiency. Section 6653(a)(2) was enacted to apply the interest component.
In this case, the taxpayers claimed NOL carrybacks, arising from a tax shelter in 1983, on their 1980 tax returns. The Service issued penalty-only notices of deficiency for 1980, asserting additions under I.R.C. §§ 6653(a)(1) and (a)(2). Section 722(b)(2) of ERTA states that the interest element of the addition applies “to taxes the last date prescribed for payment of which is after December 31, 1981.” Payment of the taxpayers’ 1980 tax was due by April 15,1981.
The General Explanation of the Economic Recovery Tax Act of 1981 prepared by the staff of the Joint Committee on Taxation provides that section 6653(a)(2) applies “for the period beginning on the last day for payment of the underpayment (i.e., the due date of the return without regard to any extension of time for payment) and ending on the date of the assessment.” This language supports that whether section 6653(a)(2) applies to an underpayment is determined by when the related tax return and payment are due.
Handel v. Commissioner,
The regulations for the accuracy-related negligence penalty under section 6662(c) include a special transitional rule for carry-backs. The inference taken from the regulation is that absent a special rule the negligence penalty or addition in effect for the carryback year applies to the underpayment attributable to the carryback. There is no similar special rule for I.R.C. § 6653(a)(2).

Notes
.No FSAs are in the record, and the district court did not inspect any in camera. Sworn statements of the Assistant Chief Counsel (Field Service), an Associate Chief Counsel, and an attorney in the Office of the Assistant Chief Counsel (Disclosure Litigation) stated that FSAs are not widely distributed, and are not abstracted, or arranged in a manner to make them easily accessible. After briefing in this case had begun, the Justice Department attorneys representing the IRS learned that those statements were incorrect. In a commendable display of candor, they informed the court and Tax Analysts that until October 1993, the Office of Chief Counsel summarized some FSAs (including 166 of the FSAs at issue in this litigation) and distributed the summaries in the Tax Litigation Bulletin. This is a monthly publication circulated to attorneys handling tax litigation in the IRS's national office and in district and regional counsel offices. In the Appendix to this opinion; we include a sample FSA summary that appeared in the Tax Litigation Bulletin.
. Although the government appeals the award of attorney’s fees, it concedes that the award must stand if we otherwise affirm the district court.
. Tax Analysts also claims that the memoranda are "instructions to staff that affect a member of the public," 5 U.S.C. § 552(a)(2)(C). The district court did not reach this argument.
.
Kennecott
left open the question whether other sources of law might authorize additional remedial orders in FOIA cases. See
. Another subsection, § 6103(e)(7), permits disclosure of return information to the taxpayer if this "would not seriously impair Federal tax administration,” and § 6103(j)(4) prohibits persons who receive return information pursuant to § 6103(j) from revealing it "except in a form which cannot be associated with, or otherwise identify, directly or indirectly, a particular taxpayer." See also 26 U.S.C. § 6108(c).
. The others relate to classes of taxpayers rather than individuals. The IRS concedes that any return information in them may be redacted.
. Cases sustaining IRS claims of exemption under § 6103(b)(2) include
Currie v. IRS,
.
Vietnam Veterans of Am. v. Department of the Navy,
. There is an exception to the Administrative Procedure Act’s notice and comment rulemaking provisions for "interpretive rules [and] general statements of policy.” 5 U.S.C. § 553(b). In applying this provision, we have distinguished binding rules from policy statements and interpretive rules, which are not binding and which leave agency decisionmakers with some discretion.
See, e.g., Vietnam Veterans of Am. v. Secretary of the Navy,
. In an affidavit, an Assistant Chief Counsel asserts that FSAs and Technical Advice Memo-randa "differ greatly in content.” But he fails to identify any great differences. He states that Technical Advice Memoranda concern the "interpretation and proper application of tax law, tax treaties, regulations, revenue rulings, notices, and other precedents.” On the other hand, FSAs involve “a much wider range of authority,” including "the Internal Revenue Code and other federal statutes, and rules of procedure for federal courts.” FSAs, he continues, discuss judicial opinions "rather than ... agency regulations, rulings, or notices." Are we to suppose that Technical Advice Memoranda are not concerned with judicial opinions? A Supreme Court decision interpreting a section of the Internal Revenue Code is as much a part of "tax law” as an IRS regulation. And in fact hundreds of Technical Advice Memoranda do discuss Supreme Court cases, to say nothing of cases from other courts. E.g., Tech. Adv. Mem. 9721002 (May 23, 1997); Tech. Adv. Mem. 9717006 (Apr. 25, 1997).
. Federal Rule of Civil Procedure 26(b)(3) allows discovery of materials prepared in anticipation of litigation only upon a showing of "substantial need,” but in all cases "the court shall protect against disclosure of the mental impressions, conclusions, opinions, or legal theories of an attorney ... concerning the litigation.” The point of the rule is that while all materials prepared in anticipation of litigation are work product and protected from discovery by other parties, a sufficient showing of need may overcome that protection with respect to factual materials, but not with respect to deliberative materials. This does not mean that factual materials are not work product; it means only that they receive a lower degree of protection under the Federal Rules than deliberative work product.
