Plаintiff V. Lamar Skelton brought this suit under the Freedom of Information Act (FOIA), 5 U.S.C. § 552, to compel disclosure of material deleted from documents furnished him in response to a FOIA request. The district court granted summary judgment for the defendant agency, the United States Postal Service. Still seeking disclosure of material deleted from a single document, plaintiff appeals. We affirm.
I. Background
Skelton is a former employee of the Fort Worth post office. He retired from the Service on disability pay after suffering a work-related injury. Since his retirement, he has spent much time representing other postal employees or former employees in pursuing various claims against the agency.
*37 On April 5, 1978, Skelton went to the Fort Worth post office with another former employee, Jerald Miller. The two wished to see employment records pertaining to a compensatiоn claim that Miller was pursuing. Two employees in the personnel office, Slaten and Saul, gave Skelton and Miller all the records they requested except for medical records. Slaten and Saul told Skelton and Miller to go to the separate medical unit to obtain those records.
According to Skelton’s account, he and Miller went to the medical unit and found it closed. They returned to the personnel offiсe and asked a nurse, Goodson, to get the records for them. When she declined to do so, Skelton reminded her that he had made an appointment to view the records and said that he should not be kept waiting indefinitely. Lanier Luttrell, the director of personnel, intervened and told Skelton not to interfere with his workers. When Skelton attempted to persuade Luttrell to honor his scheduled appointment and initiate efforts to produce the records, Luttrell ordered Skelton and Miller to leave the personnel office.
According to Luttrell’s account, Skelton had ordered Goodson to stop what she was doing and immediately procure the records. When she failed to do so, Skelton “began to talk down to her in a very loud voice and acted in a tyranical [sic] manner.” His actions disrupted the business of the office and startlеd non-employees who were on the premises. Luttrell intervened and told Skelton that if he filled out a proper, written request for the records they would be retrieved. Skelton persisted in arguing and Luttrell told him to leave the office. Skel-ton remained and continued to argue until Luttrell indicated that he was about to phone for assistance to have Skelton removed by force.
Two days later, Skelton wrote a letter to the agency’s Consumer Advocate complaining about the incident and requesting that the agency take internal disciplinary action against Luttrell, Goodson, Slaten, and Saul. He charged each of the four with various violations of the code of conduct for postal employees.
Because disciplinary matters are not handled by the Consumer Advocate’s office, that office referred Skeltоn’s letter to the agency’s department of employee and labor relations. On May 25, 1978, Robert B. Gould, the Regional Director of Employee and Labor Relations for the Southern Region of the Postal Service, wrote to Skelton and informed him that “[t]he matter has been thoroughly reviewed and based on the report we received no further action is deemed warranted in the matter” (emphasis added).
Skelton then filed the FOIA request that is the subject of this lawsuit. He requеsted all records relating to his letter of complaint and the agency’s decision not to take disciplinary action. Within two weeks, the agency produced the requested documents, but it deleted a section from a memorandum by Luttrell. While the parts of the Luttrell memorandum giving Luttrell’s version of the incident were disclosed, the deleted section contained material which the agency accurately described in an interrogatory as
the opinions of Lanier Luttrell concerning: Plaintiff’s activities representing present and former postal employees in various types of disputes with the Postal Service; of his motivations for assuming such representation; of Plaintiff’s relations with the personnel at the Fort Worth Post Office; and of the administrative burden imposed on the Post Office by its obligation to respond to Plaintiff’s Freedom of Information Act (FOIA) and Privacy Act (P.A.) requests.
In its letter transmitting the documents, the agency claimed that the deleted material was exempt from disclosure under 5 U.S.C. § 552(b)(5).
After an unsuccessful administrative appeal, Skelton brought this action.
II. Exemption 5
The district court upheld the agency’s determination that the deleted material was exempt from disclosure under 5 U.S.C. § 552(b)(5) (“Exemption 5”). That provi *38 sion exempts from disclosure “inter-agency or intra-agency memorandums оr letters which would not be available by law to a party other than an agency in litigation with the agency.” The district court agreed with the agency’s position that the deleted material would not be available in civil litigation because it is protected by the executive, or “deliberative process,” privilege. 1
In
NLRB v. Sears, Roebuck & Co.,
The deleted material, which this court and the district court have reviewed in camera, comes within both the scope and purpose of the privilege. 2 Luttrell’s opinions concerning plaintiff’s activities, motivations, and strained relationships with the postal employees were clearly a part of the deliberative process by which the agency decided not to take internal disciplinary action against its employees. Moreover, the possibility of disclosure might well have inhibited Luttrell from advising his superiors in Washington of his view of the circumstances surrounding Skelton’s complaint.
Skelton argues that because Luttrell’s opinion was based on facts, it cannot be an opinion concerning “legal or policy matters” within the meaning of
Sears,
We agree with Judge Thornberry’s observation in
Wu
that there is no “ironclad”
*39
test by which to determine whether material is “deliberative” or “predominantly, if not purely, factual.” “A careful case-by-case analysis of the material sought is thus necessary.”
Wu,
Skelton also argues that Luttrell’s memorandum was simply the statement of a witness to the incident in the post office. While part of Luttrell’s memorandum is Luttrell’s factual version of the incident, that part has been fully disclosed to Skel-ton. In the deleted part of the memorandum, Luttrell was speaking not as a witness but as an administrator with an opinion concerning the proper disposition of Skel-ton’s complaint. His оpinion, therefore, was within the scope of Exemption 5.
III. The Exception to Exemption 5
In
Sears,
the Supreme Court held that “if an agency chooses
expressly
to adopt or incorporate by reference an intraagency memorandum previously covered by Exemption 5 in what would otherwise be a final opinion, that memorandum may be withheld only on the ground that it falls within the coverage of some exemption other than Exemption 5.”
The term “final opinion” is not defined in the section of the Sears opinion establishing the incorporation by reference exception. See
We conclude that
Sears
is not controlling because the letter to Skelton was not a “final opinion[] . .. made in the adjudication of [a] case[]” within the meaning of § 552(a)(2)(A). The doсuments at issue in
Sears
were legal memoranda that explained the NLRB’s reasons for dismissing an unfair labor charge filed by a private party. The private party was attempting to vindicate statutorily protected rights,
see
29 U.S.C. § 158(a), (b), through a statutorily created procedure,
id.
§ 160(b).
See Sears,
By contrast, Skelton’s original letter of complaint invoked no substantive statutory right and no statutory procedure for vindicating it. No statute directed the agency to mаke any determination concerning Skelton’s letter. Skelton points to no statute or regulation that would make him a party to an internal disciplinary proceeding. He would not be entitled to personal relief in such a proceeding. The agency’s letter responding to Skelton’s complaint was thus not the adjudication of a “case” that is at all similar to the “case” at issue in Sears.
Moreover, we think it extremely unlikely that Congress intended a letter sent in response to a citizen’s letter of complaint to *41 be a “final opinion” subject to the indexing requirement of § 552(a)(2). That requirement was designed to help the citizen find agency statements “having precedential significance” when he becomes involved in “a controversy with an agency.” H.R.Rep. No.1497, 89th Cong., 2d Sess. 8, reprinted in [1966] U.S.Code Cong. & Ad.News 2418, 2425. A letter like that sent to Skelton hardly has “precedential significance.” Wе think that by referring to “final opinions . . . made in the adjudication of cases,” Congress was referring to explanations of decisions in proceedings, like that in Sears, in which a party has a right to set the agency decision-making process in motion and obtain a determination concerning the statute or other laws the agency is charged with interpreting and administering.
Our conclusion that the agency’s letter to Skelton was not a “final opinion” undеr § 552(a)(2)(A), however, does not end the matter. While the
Sears
Court applied the incorporation by reference exception to § 552(a)(2)(A) “final opinions,” the Court did not expressly limit the exception to such documents. Moreover, the purpose of the exception — to compel disclosure of “the reasons for a policy actually adopted,”
Even if such an expanded scope for the exception were appropriate, however, it would have no application in the present case. The letter to Skelton was not a statement of agency law. Unlike the memoran-da at issue in Sears, the letter was not an interpretation of a law that the agency was charged with administering. The agency had no duty even to entertain Skelton’s letter of complaint, much less render a “legal” decision on it. While the letter can be characterized as the adoption of a policy with regard to Skelton’s complaint, it is hardly the type of general or uniform policy that necessitаtes public disclosure.
We do not think that every writing memorializing a “decision,” no matter how insignificant or routine the “decision” is, thereby becomes a “final opinion” subject to the incorporation by reference exception.
7
To hold that the agency lost its privilege to withhold Luttrell’s opinion because of the letter it sent to Skelton would at best teach the agency not to respond to citizens’ complaints, or not to allude to any other documents when it does so.
8
At
*42
worst, such a holding would deter administrators from giving their opinions for fear that a routine response to a citizen’s complaint will be deemed an adoption of those opinions. This last result is precisely what Exemption 5 was designed to prevent.
Sears,
Therefore, we hold that Sears’ incorporation by reference exception does not apply to the agency’s letter to Skelton, and thus that Luttrell’s written opinions did not lose their Exemption 5 protection.
AFFIRMED.
Notes
. The trend among the lower courts has been to use the term “deliberative process privilege,” possibly to avoid confusion with the constitutional doctrine of executive privilege discussed in
United States v. Nixon,
. The test for determining whether the material is protected by the privilegе is not whether the private party would be able to override the privilege in civil litigation by a showing of particularized need, but whether the material would “ ‘routinely be disclosed’ in private litigation.”
Sears,
.
Compare Pacific Molasses Co. v. NLRB,
. The agency has not attempted to defend the deletion on the basis of any FOIA exemption other than Exemption 5. See 5 U.S.C. § 552(b)(l)-<9). Therefore, we do not consider whether the deletion could be justified under any other exemption, see 5 U.S.C. § 552(a)(4)(B) (in a FOIA suit, “the burden is on the agency to sustain its action”), and thus whether the question raised in this part of our opinion could be avoided.
. The district court held that, even if the “report” referred to in the letter was the Luttrell memorandum, any reference to it was too uncertain tо be an “express” adoption within the meaning of
Sears.
The court relied on
Swisher v. Department of the Air Force,
Because we decide this case on other grounds, we express no opinion on whether a reference to an undisclosed document must refer to a specific portion of the document for there to be an express incorporation of that portion under Sears.
. The Court’s first reference to a “final opinion” in
Sears
was in its discussion on the scope
of
Exemption 5. See
. Therefore, we decline to adopt the definition of “final opinion” contained in
Bristol Meyers [sic] Co. v. FTC,
The position [that every post-decisional document explaining the reasons for a decision is a “final opinion”], if pushed to its logical limits, could virtually eliminate the governmental privilege. Every rejection of a proposal, no matter how infeasible or insignificant, would become a “final decision” of an agency. True, the rejection of a policy does embody a decision; but neither the language of Exemption 5 nor the hоlding in Sears demands that such a narrow interpretation of the governmental privilege be adopted in order to protect the public interest in disclosure.
Id. at 660 (dictum).
. The district court rejected this argument, relying on the Court’s statement in
Sears
that FOIA “requires disclosure of certain documents which the law requires the agency to prepare or which the agency has decided for its own reasons to create.”
