Ramon Lopez appeals the District Court’s decision in which the court held that he was not entitled to certain documents related to a grand jury investigation *1347 under the Freedom of Information Act (“FOIA”). Specifically, the court held that the documents requested by Lopez fell within the third class of documents exempted from FOIA: documents protected by other statutes (in this case, documents covered by Rule 6(e) of the Federal Rules of Criminal Procedure). See Memorandum Opinion, Lopez v. U.S. Dep’t of Justice, No. 99-1722, slip op. at 4-5 (D.D.C. filed Mar. 19, 2001) (“Memo Order”). See also Memorandum Denying Reconsideration, Lopez v. U.S. Dep’t of Justice, No. 99-1722, slip op. at 6-7 (D.D.C. filed Jan. 21, 2003) (“Denial of Reconsideration”). Lopez contends that the documents requested do not fall under the purview of Rule 6(e), and therefore are not covered by FOIA Exemption 3. Because we agree with the District Court’s conclusion that dates on which grand jury subpoenas and requests for production, writs of testifican-dum and witness debriefings are all items that inherently reveal secret matters occurring before the grand jury, we affirm in part the court’s grant of summary judgment. But because dates on which prosecutors interviewed prospective grand jury witnesses do not inherently reveal secret matters occurring before a grand jury, and because the Government has failed to demonstrate how disclosing the date of any particular witness interview would reveal a protected aspect of the grand jury, we remand this case to the District Court, instructing it to order the Department of Justice to release the dates on which it interviewed grand jury witnesses prior to testimony.
I. Background
On June 19,1990, Appellant Lopez (“Lopez”) was charged in District Court with possession of cocaine with intent to distribute, and conspiracy to possess cocaine. In September 1991 he was tried and convicted on all counts; he was sentenced in January of the following year. Throughout the trial and sentencing, Lopez was represented by A. Scott Miller (“Miller”). With new counsel, Lopez appealed. The conviction was affirmed.
Lopez later learned that the grand jury investigating him had also investigated Miller. On January 12,1994, Miller pleaded guilty to money laundering and other charges. Lopez moved to vacate his own sentence pursuant to 28 U.S.C. § 2255 (permitting collateral attack on convictions).
Beginning in 1997, Lopez began to file FOIA requests seeking information regarding the grand jury investigation from the U.S. Department of Justice (“DOJ”). In June 1999, Lopez commenced, pro se, a civil action under FOIA, 5 U.S.C. § 552, and the Privacy Act of 1974, 5 U.S.C. § 552a, to secure the documents requested. On February 23, 2000, in response to an order of the District Court, Lopez clarified and limited the scope of his requests. The requests were revised over the course of the litigation. By the time the District Court issued its Memo Order, they had taken the following form:
1) “All reports of investigations (or seg-regable portions) during civil or criminal investigations of A. Scott Miller from 1988 through January 13,1994, including dated handwritten notes, interviews and surveillance by agents of the United States Customs Service.” [“Request One”]
2) “Copies of any and all subpoenas, or segregable portions of it, writs of testifi-candum, or requests for production of federal or state prisoners before Grand Jury 91-7 or any other grand jury investigating Miller as a target or subject, or for interviews or debriefings.” [“Request Two”]
*1348 3) “Copies of the Report of Investigation closing the first investigation against Miller, opening the second investigation against him, and a report as a result of an interview between Miller and Customs agents in or around May, 1991, which resulted in a false statement charge against Miller.” [“Request Three”]
Lopez, Memo Order, slip op. at 3.
With regard to Request Two, Lopez requested that the District Court order the DOJ to produce a
Vaughn
index of the documents being withheld.
See Vaughn v. Rosen,
In support of its motion for summary judgment, the DOJ cited as a reason for its failure to disclose the sought-after documents: those matters were “specifically exempted from disclosure by statute.” 5 U.S.C. § 552(b)(3) (“Exemption 3”). The “statute” invoked here was Rule 6(e) of the Federal Rules of Criminal Procedure (secrecy of grand jury proceedings). In March 2001, the District Court granted DOJ’s motion for summary judgment regarding the request for grand jury information, per Exemption 3. The court did not address the issue of segregability of dates or other information. Lopez filed a motion for reconsideration, in which he agreed that
disclosure of the subpoenas and writs of testificandum, which would reveal the identities of the witness before the grand jury is prohibited under Rule 6(e) .... However, disclosure of segregable portions of those documents, e.g., the dates of the documents were prepared, issued, etc., are not prohibit [sic], does not violated [sic ] the core of the Rule.
Plaintiffs Motion for Reconsideration, Clarification of March 19, 2001 Order at 4 (emphasis in original).
On March 11, 2002, the Court granted Lopez’s renewed motion requiring DOJ to file an unredacted Vaughn index listing the dates of 15 reports of investigation, but not dates on which subpoenas were issued. The DOJ filed the Vaughn index a few weeks later.
Finally, in January 2003, the District Court granted the DOJ summary judgment with respect to FOIA Requests One and Three, per FOIA’s Exemption 7(C) (unwarranted invasion of personal privacy). Denial of Reconsideration at 14 (citing 5 U.S.C. § 552(b)(7)(C)).
Lopez timely field this appeal. On March 29, 2004, this Court granted the DOJ’s motion for summary affirmance on the issues other than the dates in the grand jury documents.
Lopez v. U.S. Dep’t of Justice,
No. 03-5192,
II. Analysis
The standard governing a grant of summary judgment in favor of an agency that claims it has fully discharged its FOIA disclosure obligations is well established .... [T]he agency must show, viewing the facts in the light most favor *1349 able to the requester, that there is no genuine issue of material fact. ... We review the issue de novo on the district court record.
Steinberg v. DOJ,
This Court recognized long ago that requests for documents related to grand jury investigations implicate FOIA’s third exemption, because Rule 6(e) of the Federal Rules of Criminal Procedure prohibits government attorneys and others from “diselos[ing] a matter occurring before the grand jury.” Fed. R. CRiM. P. 6(e)(2)(B). This is not to say that Rule 6(e) draws “a veil of secrecy ... over all matters occurring in the world that happen to be investigated by a grand jury.”
SEC v. Dresser Industries, Inc.,
This Court need not evaluate the revelatory characteristics of every individual document in each case before it. As the Supreme Court suggested, “categorical decisions may be appropriate and individual circumstances disregarded when a case fits into a genus in which the balance characteristically tips in one direction.”
DOJ v. Reporters Committee for the Freedom of the Press,
Grand Jury Subpoenas:
This Court has recognized that the term “grand jury subpoena” is in some respects a misnomer, because the grand jury itself does not decide whether to issue the subpoena; the prosecuting attorney does.
Doe v. DiGenova,
“Writs of Testificandum” and Requests for Production of Prisoners: Lopez’s Request Two is ambiguous to the extent that it does not specify whether “writs of testi-ficandum” refers to the aforementioned “subpoenas ad testificandum” or “writs of habeas corpus ad testificandum.” But because the following item in Request Two is “requests for production of federal or state prisoners,” the ambiguity need not be resolved here.
Writs of habeas corpus
ad testifican-dum,
when submitted by federal prosecutors to secure the presence of prisoners before the grand jury, are governed by the same rules that govern the issuance of subpoenas: Rule 17 of the Federal Rules of Criminal Procedure.
U.S. v. Garrard,
Preliminary Witness Interviews:
Prosecutors often interview witnesses in advance of grand jury testimony. In considering whether the dates of such interviews tend to reveal the inner workings of a grand jury, we must “differentiate between ... [the prosecutor’s] own investigation, and ... a
grand jury’s
investigation, a distinction of the utmost significance.”
In re Sealed Case No. 99-3091,
Because a preliminary interview may serve the distinct interests of the prosecutor
qua
prosecutor or of the prosecutor
qua
“grand jury facilitator,” the date of a preliminary interview does not on its face convey any information about “some secret aspect of the grand jury’s investigation.” In many cases, revealing the dates of preliminary interviews conducted for the purposes of “screening” potential witnesses may in fact “tend to reveal some secret aspect of the grand jury,” but we cannot, on the record before this Court, make such a finding on a
categorical
basis. The Government has failed to meet its burden of demonstrating some “nexus between disclosure and revelation of a protected aspect of the grand jury’s investigation.”
SCPR,
*1351 Subsequent Witness Debriefings: Just as preliminary interviews may serve the purposes of the prosecutor’s own investigation or the purposes of the prosecutor’s role with respect to the grand jury, post-testimony debriefings may also serve dual purposes. But pre-testimony interviews and post-testimony debriefings differ in one material respect: a post-testimony debriefing of a witness inherently indicates that the witness did, in fact, testify before the grand jury. In this respect, a post-testimony debriefing is much more akin to a grand jury subpoena than to a pre-testimony interview: just as a subpoena indicates that the grand jury wants a witness to testify, a debriefing indicates that the grand jury wanted a witness to testify (and that the witness did, in fact, testify). In either case, there is a nexus between disclosure of the information and revelation of the grand jury’s strategy or direction in the past. Therefore, just as we hold that the issuance dates of grand jury subpoenas fall within the third exemption to FOIA, we hold that the dates of post-testimony witness debriefings categorically fall within the third exemption to FOIA.
III. Conclusion
Because we hold that FOIA’s Exemption 3, incorporating Rule 6(e) of the Federal Rules of Criminal Procedure, categorically exempts (i) issuance dates of grand jury subpoenas, (ii) writs of habeas corpus ad testificandum and any other type of request of production of prisoners for the purposes of grand jury testimony, and (iii) the dates of post-testimony debriefings of grand jury witnesses, we affirm in part the District Court’s grant of summary judgment. But because we hold that the exemption does not include all preliminary interviews conducted by prosecutors supervising grand jury investigations, and because the Government has failed to prove an exemption should be given in the circumstances of this case, we reverse in part the District Court’s grant of summary judgment and remand the case for further proceedings consistent with this opinion. We instruct the District Court, upon remand, to order the Government to release the dates it interviewed grand jury witnesses.
