CHURCH OF SCIENTOLOGY OF CALIFORNIA, Plaintiff,



                                       v.



                      INTERNAL REVENUE SERVICE, Defendant.



                              Civ. A. No. 80-3239.



                          United States District Court,



                              District of Columbia.



                                 June 24, 1983.



  Taxpayer brought action under the Freedom of Information Act to compel



 Internal Revenue Service to release certain documents claimed by agency to be



 exempt from disclosure.  On Internal Revenue Service's motion for summary



 judgment, the District Court, Norma Holloway Johnson, J., held that:  (1)



 taxpayer was estopped from relitigating its claim to access to documents at



 issue in prior proceeding;  (2) Internal Revenue Service demonstrated that its



 withholding of certain documents was rational and not beyond bounds of its



 discretionary authority under provision of Internal Revenue Code governing



 disclosure of return information to persons having material interests therein;



 and (3) Internal Revenue Service's efforts to locate materials responsive to



 taxpayer's request were reasonable and adequate as a matter of law.



  Ordered accordingly.







 [1] JUDGMENT



 Taxpayer was estopped under doctrine of res judicata from relitigating its



 claim to access to documents sought in prior Freedom of Information Act action,



 in view of fact that defendant Internal Revenue Service had no duty to justify



 new bases for nondisclosure of documents at issue in prior action.  5



 U.S.C.A. s 552 et seq.







 [2] INTERNAL REVENUE



 Documents relating to ongoing litigation in United States Tax Court but



 generated or received by defendant Internal Revenue Service subsequent to its



 preparation of index in Tax Court case constituted return information within



 statutory definition.  26 U.S.C.A. ss 6103 et seq., 6103(b)(2),



 (b)(2)(A), 7213.







 [3] INTERNAL REVENUE



 Provision of Internal Revenue Code governing disclosure of return information



 to persons having material interests therein is sole standard governing



 disclosure or nondisclosure of tax return information, notwithstanding Freedom



 of Information Act.  5 U.S.C.A. s 552 et seq.;  26 U.S.C.A. s 6103 et



 seq.







 [4] INTERNAL REVENUE



 Since revelation of certain documents pertaining to ongoing tax court



 litigation would affect defendant Internal Revenue Service's ability to defend



 its position in that litigation, IRS had demonstrated that its withholding of



 documents from taxpayer was rational, and not beyond bounds of its



 discretionary authority under provision of the Internal Revenue Code governing



 disclosure of return information to persons having material interests



 therein.  26 U.S.C.A. s 6103 et seq.







 [5] RECORDS



 In determining whether claim of exemption for clearly unwarranted invasion of



 privacy under Freedom of Information Act exemption may properly be asserted,



 court must balance plaintiff's interest in disclosure, public interest in



 disclosure, degree of invasion of personal privacy, and availability of any



 alternative means of obtaining requested information.  5 U.S.C.A. s



 552(b)(6).







 [6] RECORDS



 Portions of eight documents generated or received by defendant Internal Revenue



 Service subsequent to its preparation of index submitted in tax court case, but



 not relating to ongoing tax court litigation, were exempt from disclosure under



 section of the Freedom of Information Act exempting from disclosure matters



 that are personnel and medical files and similar files the disclosure of which



 would constitute a clearly unwarranted invasion of personal privacy.  5



 U.S.C.A. s 522(b)(6).







 [7] INTERNAL REVENUE



 Under provision of Internal Revenue Code governing disclosure of return



 information to persons having material interests therein, return information



 may be disclosed to third parties at discretion of agency if such parties can



 demonstrate that they are acting in capacity of designee of individual



 taxpayer.  26 U.S.C.A. s 6103 et seq.







 [8] RECORDS



 Defendant Internal Revenue Service properly construed relevant statutory and



 regulatory requirements in determining that scope of taxpayer's Freedom of



 Information Act request was limited to data pertaining to it.  5 U.S.C.A. s



 552 et seq.







 [9] INTERNAL REVENUE



 Excised portions of certain documents were properly withheld by Internal



 Revenue Service from taxpayer since they all related to individuals and



 entities other than taxpayer.  5 U.S.C.A. s 552 et seq.







 [10] RECORDS



 Request for information under the Freedom of Information Act does not impose



 burden upon agency to reorganize its files, but does impose a firm statutory



 duty to make reasonable efforts to satisfy a FOIA request.  5 U.S.C.A. s 552



 et seq.







 [11] RECORDS



 Efforts of defendant Internal Revenue Service to locate materials responsive to



 taxpayer's request under Freedom of Information Act were reasonable and



 adequate as a matter of law.  5 U.S.C.A. s 552 et seq.







 [12] RECORDS



 Since taxpayer in Freedom of Information Act action could not be found to have



 met threshold requirement that it substantially prevailed, it was not entitled



 to award of attorney fees.  5 U.S.C.A. s 552 et seq.



  *1166 George T. Volsky, Washington, D.C., for plaintiff.



  John J. McCarthy, Edward J. Snyder, Richard L. Switzer, U.S. Dept. of Justice,



 Tax Div., Washington, D.C., for defendant.



                               MEMORANDUM OPINION







  NORMA HOLLOWAY JOHNSON, District Judge.



  Plaintiff Church of Scientology of California (hereinafter California Church)



 brings this action under the Freedom of Information Act (FOIA) [FN1] to compel



 the Internal *1167 Revenue Service (IRS) to release certain documents



 claimed by that agency to be exempt from disclosure under FOIA.  This matter is



 now before the Court on defendant's motion for summary judgment. [FN2]  For the



 reasons set forth herein, the Court finds that no material issues of fact



 remain in dispute, and that defendant is entitled to summary judgment as a



 matter of law.  Accordingly, defendant's motion for summary judgment will be



 granted.







      FN1. 5 U.S.C. s 552 et seq. (1976 & Supp V 1981).







      FN2. Arthur L. Lappen, Chief Branch 3 Disclosure Litigation Division, IRS,



     has been dropped as a named defendant in this action at the plaintiff's



     request.







                                     DISCUSSION



  I. Plaintiff's FOIA Request



  In its original request under FOIA submitted on May 16, 1980, plaintiff sought



 the release of virtually all materials contained in IRS files nationwide



 which pertained specifically to the California Church, and to Scientology, in



 general. [FN3]  Included within the scope of plaintiff's request were documents



 sought by plaintiff in its First Request of Production of Documents in an



 ongoing action before the United States Tax Court entitled Church of



 Scientology of California v. Commissioner of IRS, Docket No. 3352-78



 (U.S.T.C.) (hereinafter referred to as Tax Court case).  Plaintiff's FOIA



 request thereby included all materials received or generated by IRS in



 connection with the Tax Court case, as well as materials indexed, but adjudged



 exempt from disclosure, in a previous FOIA action entitled Church of



 Scientology of California v. IRS, Civil No. CV 74-3465-RJK (C.D.Cal. October



 29, 1976), appeal dismissed, No. 77-1365 (9th Cir.1978) (hereinafter



 referred to as a FOIA I).







      FN3. Plaintiff's May 16, 1980, FOIA request sought



     Copies of all information relating to or containing the names of



     Scientology, Church of Scientology, any specific Scientology Church or



     entity identified by containing the words Scientology, Hubbard, and/or



     Dianetics in their names, L. Ron Hubbard or Mary Sue Hubbard in the form of



     a written record, correspondence, document, memorandum, form, computer



     tapes, computer program or microfilm;  which is contained in any of the



     following systems of records, including but not limited to those located at



     the National office, Regional offices, Service Centers, District offices,



     or local IRS offices [four page list identifying IRS record systems by



     appropriate code numbers is omitted].



     Plaintiff also sought IRS personnel training materials located in



     Covington, Kentucky, and requested the release of "copies of file labels or



     tabs identifying any and all files containing information requested



     herein."  Letter of Rev. James Morrow to Chief, Disclosure Staff, IRS,



     dated May 16, 1980.







  In its May 16, 1980, request, plaintiff acknowledged that the volumes of



 materials involved would make it impossible for the IRS to respond within the



 statutory ten-day period, but asked that the California Church be apprised of



 an anticipated schedule for response.  IRS wrote to plaintiff on July 22, 1980,



 to ask plaintiff to agree to a voluntary extension of defendant's time for



 response until August 29, 1980.  Plaintiff filed an appeal with IRS on



 September 17, 1980, after no further response from IRS had been forthcoming.



 Plaintiff did not await defendant's response to the appeal, but instead



 commenced the instant action.



  Defendant's determination of plaintiff's FOIA appeal was issued on January 14,



 1981.  The scope of plaintiff's FOIA request was found to be properly limited



 to materials pertaining to the California Church, and the proper extent of



 the agency's search was found to be limited to the IRS National office. [FN4]



 Further, defendant construed *1168 plaintiff's FOIA request as encompassing



 materials falling into four categories:  (1) those documents withheld from



 disclosure and adjudged exempt in FOIA I;  (2) those documents indexed in



 connection with the Tax Court case and relating to that case;  (3) those



 documents generated subsequent to the Tax Court case;  and (4) any documents



 relating to the California Church which were generated subsequent to the Tax



 Court case index and are located in the IRS National office.  Letter of Gerald



 G. Portney, Assistant Commissioner (Technical), IRS to Rev. James Morrow, dated



 January 14, 1981, p. 3.  Defendant denied plaintiff's appeal in substantial



 part after determining that (1) principles of res judicata and collateral



 estoppel barred plaintiff from relitigating its claim to access to FOIA I



 documents;  and (2) the remaining documents at issue were exempt from



 disclosure under 26 U.S.C. s 6103 et seq. (1976 & Supp. V 1981) and 5



 U.S.C. s 552(b)(6) (1976 & Supp. V 1981).







      FN4. Although defendant limited its search to its National office,



     defendant did search and locate documents lodged in Covington, Kentucky,



     and in the offices of the District Counsel for Los Angeles.  The other



     sites searched by defendant included the following:  Offices of the



     Commissioner;  Deputy Commissioner;  Assistant Commissioner (Compliance);



     Assistant Commissioner (Technical);  Assistant Commissioner (Employee



     Plans/Exempt Organizations);  Assistant Commissioner (Inspection);  Audit



     Division;  Criminal Investigation Division;  Office of International



     Operations;  Covington, Kentucky office;  Returns Processing and Accounting



     Division;  Collection Division;  Appeals Division;  Chief Counsel;  Deputy



     Chief Counsel (Administrative);  Deputy Chief Counsel (Technical);  Deputy



     Chief Counsel (Litigation);  Administrative Services;  Criminal Tax



     Division;  Disclosure Litigation Division;  Employee Plans and Exempt



     Organization Division;  General Litigation Division;  Interpretive



     Division;  Legislation and Regulations Division;  and Tax Litigation



     Division.







  On June 18, 1982, the Court denied plaintiff's motion for a detailed



 justification, itemization and indexing by the defendant of the withheld



 materials as approved by the Court in Vaughn v. Rosen, 484 F.2d 820



 (D.C.Cir.1973), cert. denied, 415 U.S. 977, 94 S.Ct. 1564, 39 L.Ed.2d 873



 (1974), and granted defendant's motion to submit for in camera inspection



 certain documents located at the IRS National office.  The Court also ordered,



 sua sponte, that all documents responsive to plaintiff's request and related to



 the Tax Court case be submitted for in camera review.  Submission of the



 documents within the scope of the Court's June 18, 1982, Order has been



 accomplished, and defendant now urges the Court to find that the documents



 remaining at issue are properly exempt from disclosure. [FN5]







      FN5. Plaintiff no longer seeks disclosure of the documents indexed by



     defendant in the Tax Court case.







  II. Defendant's Motion For Summary Judgment



  A. FOIA I Documents



  In moving for summary judgment, defendant first contends that plaintiff is



 barred by the operation of the doctrine of res judicata from relitigating its



 claim to access of the documents at issue in FOIA I.  In opposition, plaintiff



 asserts that defendant must demonstrate that the res judicata effect of the



 final judgment in FOIA I has not been suspended by subsequent material changes



 in law or fact.  Plaintiff has, however, cited no authority which supports its



 contention that the burden falls upon the defendant to prove that the absence



 of any material changes in circumstances leaves undisturbed the bar to



 relitigation erected by the prior judgment.



  [1] In Commissioner of Internal Revenue v. Sunnen, 333 U.S. 591, 68 S.Ct.



 715, 92 L.Ed. 898 (1948), the Court considered the applicability of res



 judicata and collateral estoppel doctrines to determinations of income tax



 liability in different tax years.  The Court held that in the interest of



 justice, the operation of collateral estoppel "must be confined to situations



 where the matter raised in the second suit is identical in all respects with



 that decided in the first proceeding and where the controlling facts and



 applicable legal rules remain unchanged."  Id., at 600, 68 S.Ct. at 720



 (citations omitted).  The instant case presents the very situation defined in



 Sunnen as one in which the operation of collateral estoppel is appropriately



 confined.  There is no question that the documents at issue in both FOIA I and



 the instant case are identical, as are the parties.  Further, defendant does



 not seek to assert claims of exemption different from those asserted in FOIA I,



 see Wolfe v. Froehlke, 358 F.Supp. 1318, 1319-20 (D.D.C.1973), affirmed,



 510 F.2d 654 (D.C.Cir.1974) (res judicata not a bar to relitigation of



 plaintiff's claim to access to document under FOIA when agency asserts new



 basis for exemption from disclosure).  Plaintiff in the instant case correctly



 cites Sunnen for the proposition that the binding *1169 effect of a prior



 final judgment might be altered or even nullified by a "subsequent modification



 of the significant facts or a change or development in the controlling legal



 principles..."  Id., 333 U.S. at 599, 68 S.Ct. at 720.  Plaintiff, however,



 has not even alleged that any such modification in law or fact has occurred



 with regard to this action.  Nothing in the legislative history of FOIA or the



 language of that Act suggests that a defendant in an action brought under FOIA



 who alleges res judicata as an affirmative defense bears a special burden of



 proving that documents already adjudged exempt remain exempt.  See Church of



 Scientology of California v. U.S. Dep't of the Army, et al., 611 F.2d 738, 750



 fn. 7 (D.C.Cir.1979).  Where the issues, documents, and plaintiffs are



 identical in both the prior and present FOIA litigation, "[t]he issue of



 exemption cannot be relitigated."  Id. at 751.  The Court notes that



 defendant, in responding to plaintiff's FOIA request in the action sub judice,



 reviewed the 290 documents found to be exempt from disclosure in FOIA I and



 identified twenty of that total number which had been withheld in full or in



 part on the basis of 5 U.S.C. s 552(b)(7)(A). [FN6]  Affidavit of Charles W.



 Rumph, Technical Advisor, Tax Litigation Director, IRS, P 2.  These twenty



 documents were then reviewed, and defendant concluded that Exemption (b)(7)(A)



 no longer provided a basis for non-disclosure.  Id., P 3.  All documents



 previously withheld solely on the basis of Exemption (b)(7)(A) were, therefore,



 released by the defendant.  Id.  Plaintiff's contention that defendant's



 failure to justify anew the bases for non-disclosure of the documents at issue



 in FOIA I must, therefore, be rejected as without merit, and the Court must



 find that plaintiff is estopped from relitigating its claim to access to the



 FOIA I documents.







      FN6. Exemption (b)(7)(A) exempts from disclosure under FOIA those



     documents which constitute "investigatory records compiled for law



     enforcement purposes, but only to the extent that the production of such



     records would (A) interfere with enforcement proceedings..."  5 U.S.C. s



     552(b)(7)(A) (1976 Supp. V 1981).







  B. Documents Pertaining to Ongoing Tax Court Litigation



  Although plaintiff has dropped its claim to documents indexed by the defendant



 in the ongoing litigation in the U.S. Tax Court, a substantial number of



 documents relating to that action but generated or received by defendant



 subsequent to its preparation of the index in the Tax Court case remain in



 dispute.  Defendant contends that the documents constitute confidential tax



 return information within the meaning of 26 U.S.C. s 6103 et seq. (1976 &



 Supp. V 1981) and, as such, are exempt from disclosure.



  [2] The first question presented with respect to these "post-index"



 documents is whether they can, indeed, be properly characterized as



 confidential tax return information within the definition of 26 U.S.C. s



 6103(b)(2)(A). [FN7]  The Court's in camera examination of a representative



 number of the documents in question reveals that the documents each identify a



 specific taxpayer, and contain "private facts taken directly from tax returns



 or IRS comment upon the private tax situations of specific taxpayers."  King



 v. IRS, 688 F.2d 488, 494 (7th *1170 Cir.1982).  See also Neufeld v. IRS,



 646 F.2d 661 (D.C.Cir.1981).  The Court concludes, therefore, that these "post-



 index" documents clearly constitute return information within the statutory



 definition.







      FN7. "Return information" is defined as encompassing



     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



     Secretary with respect to a return or with 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,



     forfeiture, or other imposition, or offense...



     26 U.S.C. s 6103(b)(2)(A) (1976 & Supp. V 1981).  Criminal penalties



     attach to the unauthorized disclosure of data as set forth in s 6103.



     26 U.S.C. s 7213.  In addition to the specified instances where



     disclosure is authorized, disclosure of data under s 6103 may be made



     "in a form which cannot be associated with, or otherwise identify, directly



     or indirectly, a particular taxpayer."  s 6103(b)(2).







  Having concluded that the contested materials are return information, it must



 be determined to what extent, if any, the provisions of section 6103 affect



 plaintiff's claim to access to those materials under FOIA.  Defendant relies



 on Zale v. IRS, 481 F.Supp. 486 (D.D.C.1979) to support its contention that



 the "particularized disclosure scheme" of section 6103 effectively pre-empts



 the more general disclosure criteria of FOIA.  Id. at 489.  Defendant thus



 contends that in accordance with Zale, the Court's review of defendant's



 decision to withhold the return information sought by plaintiff will not be



 subject to the de novo review available under FOIA, but will properly be



 limited to the determination of whether "the decision to withhold was ... an



 arbitrary or unconscionable abuse of discretion."  Id. at 490.



  [3] This Court has had the opportunity to consider the applicability of FOIA



 to disclosure requests for confidential return information in a prior action



 entitled Service Employees International Union v. IRS, No. 82-1081 (decided



 January 1, 1981).  Consistent with the decision in that action, the Court today



 again adopts the rationale of Zale in holding that section 6103 "must be



 viewed as the sole standard governing release of tax return information."



 Zale v. IRS, 481 F.Supp. at 490.  Accord King v. IRS, 688 F.2d 488 (7th



 Cir.1982);  Anheuser-Busch, Inc. v. IRS, 493 F.Supp. 549 (D.D.C.1980);  but



 see, e.g. Britt v. IRS, 547 F.Supp. 808 (D.D.C.1982).



  [4] The Court must, therefore, determine whether defendant's decision to



 withhold the "post-index" documents can be upheld as rational and supported in



 the record.  Section 6103 provides but a few limited exceptions to the



 general prescription of confidentiality of return information.  Disclosure of



 return information may be made to persons deemed to have a "material interest"



 in such information as defined under section 6103(e)(1) [FN8], barring a



 determination by the IRS that disclosure "would seriously impair Federal tax



 administration."  26 U.S.C. s 6103(c) and (e)(6) (1976 & Supp. V 1981).  In



 the instant action, defendant concedes that plaintiff has a material interest



 in the documents in question, but has determined that disclosure would



 seriously interfere with defendant's duties in connection with the ongoing Tax



 Court litigation by revealing its litigation strategy and attorney work



 products.  In view of the ongoing nature of the Tax Court litigation, and after



 in camera inspection of a representative number of the relevant documents, the



 Court finds that those documents do relate to defendant's litigation strategy,



 and reflect the work product of attorneys employed by the defendant.  Since



 revelation of the documents would thus affect the defendant's ability to defend



 its position in the Tax Court case, the Court finds that defendant has



 demonstrated that its withholding of the documents was rational, and not beyond



 the bounds of its discretionary authority under section 6103. [FN9]







      FN8. 26 U.S.C. s 6103(e)(1) (1976 & Supp. V 1981).  Individual



     taxpayers are deemed to have a "material interest" in disclosure of their



     own return information under section 6103(e)(1).







      FN9. Even assuming, arguendo that section 6103 must be viewed as a



     qualifying exempting statute under 5 U.S.C. s 552(b)(3), see e.g.



     Chamberlain v. Kurtz, 589 F.2d 827 (5th Cir.1979), cert. denied, 444



     U.S. 842, 100 S.Ct. 82, 62 L.Ed.2d 54 (1979), and that judicial review



     would thus be in accord with the provisions of FOIA, the Court is persuaded



     after its in camera inspection of the pertinent documents that defendant's



     non-disclosure is not improper under the criteria of either section 6103



     or FOIA Exemption 3.







  C. Disclosure of Documents From IRS National Office



  Defendant has located and indexed twenty-one documents in its National office



 which are responsive to plaintiff's FOIA request.  These documents were



 generated or received by defendant subsequent to its preparation of the index



 submitted in the Tax Court case, but do not relate to the *1171 ongoing Tax



 Court litigation.  Ten of the twenty-one documents have been released in full;



 portions of the remaining eleven documents have been withheld by the defendant.



  Defendant contends that the deleted portions of eight of the eleven documents



 at issue are exempt from disclosure under 5 U.S.C. s 552(b)(6) ("Exemption



 6"), which exempts from disclosure under FOIA matters that are "personnel and



 medical files and similar files the disclosure of which would constitute a



 clearly unwarranted invasion of personal privacy."  5 U.S.C. s



 552(b)(6) (1976 & Supp. V 1981).



  [5][6] In determining whether a claim of exemption for a "clearly



 unwarranted invasion of privacy" under FOIA Exemption 6 may properly be



 asserted, a court must balance "(1) the plaintiff's interest in disclosure;



 (2) the public interest in disclosure;  (3) the degree of the invasion of



 personal privacy;  and (4) the availability of any alternative means of



 obtaining the requested information."  Church of Scientology of California



 v. Dept. of the Army, et al., 611 F.2d 738, 746 (9th Cir.1979).  See



 Department of The Air Force v. Rose, 425 U.S. 352, 96 S.Ct. 1592, 48 L.Ed.2d



 11 (1976);  Rural Housing Alliance v. U.S. Dep't of Agriculture, 498 F.2d



 73 (D.C.Cir.1974).  The Court has examined in camera those portions of each of



 the eight documents claimed by defendant to be exempt under Exemption 6 and has



 concluded that the balance of factors clearly weighs in favor of non-disclosure



 by the defendant.



  Document A-1 is comprised of "log cards" maintained by defendant.  Document A-



 6 is a ten-page document dealing largely with a draft legal opinion concerning



 plaintiff's tax-exempt status.  Document A-10 consists primarily of a letter to



 Senator Inouye from the Acting Director of defendant's Tax Litigation



 Division.  Document A-12 is a two-page memorandum concerning a prior summons



 enforcement suit against the plaintiff.  Documents A-13 and A-15 are



 "buckslips" concerning litigation against the plaintiff.  Document A-15 is a



 single-page handwritten memorandum relating to defendant's response to



 plaintiff's motion for summary judgment.  Document A-18 is a transmittal



 memorandum dealing with the filing of defendant's answer in the Tax Court case.



  In each of the documents described above, the excised portions consist of the



 names of attorneys and other personnel employed by the defendant.  The Court



 agrees with the defendant that the interest of plaintiff and the public in



 knowing which attorneys and other personnel have been assigned to certain cases



 is de minimus when weighed against the interest of the individuals involved in



 maintaining anonymity as a means of avoiding potential harassment and find,



 therefore, that the excised portions are exempt from disclosure under Exemption



 6.



  Portions of Documents A-9 and A-21 have also been withheld by defendant on the



 basis that the excised data constitute confidential third-party return



 information whose release to plaintiff is unauthorized under 26 U.S.C. s



 6103(a) (1976 & Supp. V 1981).  A single deletion in Document A-6 is also



 claimed by defendant to be proper on this basis.  Document A-20 has also been



 partially withheld as being outside the scope of plaintiff's request.



 Defendant's claims of exemption with respect to these four documents thus raise



 the threshold question of whether defendant has properly construed the scope of



 plaintiff's FOIA request to exclude all materials not pertaining to the



 California Church.



  [7] As discussed, infra, the Court finds that defendant's non-disclosure of



 data constituting return information within the definition of 26 U.S.C. s



 6103(b)(2)(A) is subject to judicial review in accordance with the criteria set



 forth under section 6103.  Under section 6103, return information may be



 disclosed to third-parties at the discretion of the agency if such parties can



 demonstrate that they are acting in the capacity *1172 of designee of the



 individual taxpayer. [FN10]  It is undisputed that in its May 16, 1980, FOIA



 request, plaintiff's representative provided defendant with the authorization



 of only the California Church.  Defendant asserts that release to plaintiff of



 any return information pertaining to the individuals and Scientology entities



 other than the California Church as listed in plaintiff's request is



 unauthorized and, therefore, proscribed under section 6103.







      FN10.  Section 6103(c) provides:



     The Secretary may, subject to such requirements and conditions as he may



     prescribe by regulations, disclose the return of any taxpayer, or return



     information with respect to such taxpayer, to such person or persons as the



     taxpayer may designate in a written request for or consent to such



     disclosure, or to any other person at the taxpayer's request to the extent



     necessary to comply with a request for information or assistance made by



     the taxpayer to such other person.  However, return information shall not



     be disclosed to such person or persons if the Secretary determines that



     such disclosure would seriously impair Federal tax administration.



     See also 26 U.S.C. s 6103(e)(6) (1976 & Supp. V 1981);  26 C.F.R. s



     601.702(c)(4)(ii)(c) (1982).







  An actionable request under FOIA for records in the possession of the IRS is



 defined under 26 C.F.R. s 601.702(c)(1) (1982) as one "which conforms in



 every respect with the rules and procedures set forth in this subpart."  A FOIA



 request which includes within its scope materials properly classified as



 "return information" under section 6103 must "establish the identity and the



 right of the person making the request to the disclosure of the records..."



 26 C.F.R. s 601.702(c)(v) (1982).  Plaintiff concedes that in accordance



 with these pertinent statutory and regulatory requirements, defendant is



 obligated to protect against the unauthorized disclosure of third-party return



 information, but contends that the California Church is so "clearly related" to



 the third parties at issue as to make additional authorization superfluous.



 Plaintiff also asserts that defendant was required by its own regulations to



 request the additional authorizations from plaintiff at the time it first



 determined such proofs were necessary, and before defendant responded to



 plaintiff's FOIA request.



  [8][9] The regulatory language quoted by the plaintiff in support of this



 latter contention provides in relevant part:



   Additional proof of a person's identity shall be required before the request



 will be deemed to have met the requirement of paragraph (c)(3)(v) of this



 section if it is determined that additional proof is necessary to protect



 against unauthorized disclosure of information in a particular case.



  26 C.F.R. s 601.702(c)(4)(ii)(C) (1982).  The Court finds that the plain



 language of the cited regulation is devoid of any requirement that defendant



 notify a requester such as plaintiff of the need for additional proof prior to



 responding to a FOIA request encompassing third-party data.  We conclude,



 therefore, that defendant properly construed the relevant statutory and



 regulatory requirements in determining that the scope of plaintiff's FOIA



 request was limited to data pertaining to the California Church.  In view of



 defendant's conceded obligation to protect against the unauthorized disclosure



 of third-party return information, the Court finds that the plaintiff's



 contention that additional proof would be superfluous is without merit. [FN11]



 Having determined that the scope of plaintiff's request was properly construed



 by defendant as limited to documents relating to the California Church, the



 Court turns to the portions of the four documents withheld from disclosure as



 outside the proper scope of plaintiff's request.  After an in camera



 examination of these four documents in their entirety, it is clear that the



 excised portions all relate to individuals and entities other than the



 California Church.  The Court thus finds that the excised portions were



 properly withheld.







      FN11. That plaintiff's contention is without merit is particularly



     apparent when the absence of any indication by plaintiff of any legal



     relationship between plaintiff and the third-parties at issue is



     considered.







  [10] The sole remaining question concerning defendant's response to



 plaintiff's *1173 request is whether defendant has demonstrated, as a matter



 of law, that its search for responsive documents was adequate.  Plaintiff



 contends that the Court cannot find defendant's search to be adequate in view



 of defendant's arbitrary and capricious refusal to search all IRS field



 offices.  It is established in this Circuit that a request for information



 under FOIA does not impose a burden upon an agency to reorganize its files,



 "but does [impose] a firm statutory duty to make reasonable efforts to satisfy"



 a FOIA request.  Founding Church of Scientology v. NSA, 610 F.2d 824, 837



 (D.C.Cir.1979).  (Emphasis added).  The Court must, therefore, test the



 adequacy of defendant's search in the instant case against a standard of



 reasonableness.  See McGehee v. CIA, 697 F.2d 1095 (D.C.Cir.1983).  It is



 undisputed that plaintiff directed its May 16, 1980, FOIA request to



 defendant's National office.  In its FOIA request, plaintiff stated that "this



 request is being directed to the National office so proper coordination and



 handling can occur."  Letter of Rev. Morrow to Chief, Disclosure Staff, IRS,



 p. 7.  No similar request was made by plaintiff to each IRS field office, as



 required under 26 C.F.R. s 601.702(c)(iii) (1982).



  [11] From the variety of offices searched by the defendant, it is evident



 that there is no single office or recordkeeping system which is the repository



 of all data relating to the California Church. [FN12]  Defendant has produced



 for in camera inspection a voluminous amount of materials responsive to



 plaintiff's request.  The record in this action reflects that these documents



 were located through a search of all the offices specifically identified by



 plaintiff in its request, including the Covington, Kentucky, office where IRS



 personnel have received instruction in audit procedures affecting plaintiff.



 In addition, defendant searched the District Counsel offices in Los Angeles,



 the IRS district in which plaintiff is located.  Plaintiff's assertions that



 the extent of defendant's search was inadequate would thus appear to bear only



 upon its claims, rejected today, for materials relating to individuals and



 entities other than the California Church.  In view of all of the foregoing



 considerations, the Court finds that plaintiff has failed to raise a genuine



 dispute on the issue of the adequacy of defendant's search.  The Court



 concludes, therefore, that defendant's efforts to locate materials responsive



 to plaintiff's request were reasonable and, therefore, adequate as a matter of



 law.







      FN12. The Court also notes that the documents sought by the plaintiff are



     not summaries or other compilations effected by defendant which might



     conceivably be lodged at a central site.







  [12] The final issue before the Court is plaintiff's claim for the award of



 attorney fees.  It is well-established that, at a minimum, an award of



 reasonable attorney fees to a plaintiff in a FOIA action must be based upon the



 finding that such plaintiff has "substantially prevailed."  See, e.g.,



 Chamberlain v. Kurtz, 589 F.2d 827 (5th Cir.1979), cert. denied 444 U.S.



 842, 100 S.Ct. 82, 62 L.Ed.2d 54 (1979).  It is clear that since plaintiff in



 this action cannot be found to have met this threshold requirement, plaintiff



 is not entitled the award of attorney fees.



  An Order consistent with this Memorandum Opinion will be entered on this date.



                                      ORDER



  Upon consideration of the motion by defendant for summary judgment,



 plaintiff's opposition thereto, supporting and opposing memoranda of law and



 affidavits, the in camera inspection of documents at issue in the above-



 entitled action, and the entire record herein, it is this 24th day of June,



 1983,



  ORDERED that defendant's motion for summary judgment be, and hereby is,



 granted;  and it is further



  ORDERED that this action be, and hereby is, dismissed with prejudice.
