MEMORANDUM OPINION AND ORDER
Plaintiff has sued defendants pursuant to the Freedom of Information Act ("FOIA"), 5 U.S.C. § 552(a)(4)(B), for their failure to produce various National Security Letters (NSLs) he requested. The case is before the Court on defendants' Federal Rule of Civil Procedure ("Rule") 56 motion for summary judgment. For the reasons set forth below, the motion is granted.
On April 6, 2006, plaintiff sent a FOIA request to the Federal Bureau of Investigation ("FBI") seeking NSLs issued pursuant to section 507 of the Patriot Act, 18 U.S.C. § 507. (Compl. ¶ 1; Mem. Supp. Defs.' Mot. Summ. J. at 3.) After exchanging various letters with the government, plaintiff narrowed his request to all NSLs issued pursuant to section 507 of the Patriot Act between October 1, 2003 and December 31, 2004 that pertained only to him. (Id., Ex. 1, Hardy Decl. ¶¶ 7-20; id., Ex. 2, Hr'g Tr. of 1/30/08 at 2-4.)
Defendants responded that they could not confirm or deny whether plaintiff was the subject of an NSL because such information was exempt from disclosure under FOIA Exemptions 7(E) and 2. (Id., Ex. 1, Hardy Decl. ¶ 20.) Plaintiff contends that response was improper and seeks an order requiring defendants to produce any documents responsive to his narrowed request.
To prevail on a summary judgment motion, "the pleadings, the discovery and disclosure materials on file, and any affidavits [must] show that there is no genuine issue as to any material fact and that the movant is entitled to judgment as a matter of law." Fed. R. Civ. P. 56(c). At this stage, we do not weigh evidence or determine the truth of the matters asserted. Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 249 (1986). We view all evidence and draw all inferences in favor of the non-moving party. Michas v. Health Cost Controls of Ill., Inc., 209 F.3d 687, 692 (7th Cir. 2000). Summary judgment is appropriate only when the record as a whole establishes that no reasonable jury could find for the non-moving party. Id. In a FOIA case, the Court may grant summary judgment to the government solely on the basis of affidavits if "the agency affidavits describe the documents withheld and the justifications for nondisclosure in enough detail and with sufficient specificity to demonstrate that material withheld is logically within the domain of the exception claimed." Patterson v. IRS, 56 F.3d 832, 836 (7th Cir. 1995) (quotations omitted).
The "fundamental principle" behind FOIA is "public access to Government documents." John Doe Agency v. John Doe Corp., 493 U.S. 146, 151 (1989). However, recognizing "that legitimate . . . interests could be harmed" if certain information is released, Congress balanced the public's right to know and the government's need for secrecy by requiring the government to disclose records unless they fall into one of nine exceptions. Id. at 152 (quotations omitted); see 5 U.S.C. § 552(a), (b). Moreover, the government may refuse "to confirm or deny the existence of requested records," a so-called Glomar response,*fn1 if "even acknowledging that certain records are kept would jeopardize the privacy interests that the FOIA exemptions are intended to protect." Antonelli v. F.B.I., 721 F.2d 615, 617 (7th Cir. 1983). Defendants contend that their Glomar response to plaintiff's narrowed request was proper because confirming or denying that plaintiff is the subject of an NSL would cause the very harm FOIA exemption 7(E) is designed to prevent.
FOIA exemption 7(E) allows the government to withhold:
[R]ecords or information compiled for law enforcement purposes, but only to the extent that the production of such law enforcement records or information. . . would disclose techniques and procedures for law enforcement investigations . . . , or would disclose guidelines for law enforcement investigations . . . if such disclosure could reasonably be expected to risk circumvention of the law.
5 U.S.C. § 552(b)(7)(E). This exemption applies only to techniques and procedures "generally unknown to the public" and only if "(1) the information was compiled for law enforcement purposes, and (2) [its] release could reasonably be expected to risk circumvention of the law." Blanton v. U.S. Dep't of Justice, 63 F. Supp. 2d 35, 49 (D.D.C. 1999) (quotations omitted).
Because the FBI has "a clear law enforcement mandate," defendants "need establish only a 'rational nexus'" between the FBI's law enforcement duties and the purportedly exempt information to satisfy the first requirement of exemption 7(E). Binion v. U.S. Dep't of Justice, 695 F.2d 1189, 1194 (9th Cir. 1983); see 12 U.S.C. § 3414(a)(1)(C) (requiring financial institutions to disclose customer records to any "Government authority authorized to conduct investigations of, or intelligence or counterintelligence analyses related to, international terrorism"); 15 U.S.C. § 1681u(a) (requiring consumer reporting agencies to give the FBI "the names and addresses of all financial institutions . . . at which a consumer maintains or has maintained an account . . . when presented with a[n appropriate] written request"); 18 U.S.C. § 2709(b)(1) (authorizing the FBI to obtain "the name, address, length of service, and local and long distance toll billing records of a person or entity" pursuant to an appropriate request). David Hardy, Section Chief of the FBI's Record/Information Dissemination Section, Records Management Division, says that NSLs are "indispensable investigative tools . . . in many FBI counterterrorism and counterintelligence investigations," and are used to: obtain evidence to Support Foreign Intelligence Surveillance Act ("FISA") applications for electronic surveillance, pen register/trap and trace devices, or physical searches; develop communication or financial links between subjects of FBI investigations and between those subjects and others; provid[e] evidence to initiate new investigations, expand national security investigations, or enabl[e] agents to close investigations; provid[e] investigative leads; and corrborat[e] information obtained by use of other investigative techniques. (Mem. Supp. Defs.' Mot. Summ. J., Ex. 1, Hardy Decl. ¶¶ 1, 5, 32.) In light of the FBI's essential purpose, Hardy's testimony establishes that the NSLs plaintiff seeks were generated for a law enforcement purpose.
The second requirement for exemption under 7(E) is that disclosure of the NSLs would reveal previously undisclosed "techniques . . . for law enforcement investigations" that "could reasonably be expected to risk circumvention of the law." 5 U.S.C. § 552(b)(7)(E). Moreover, even if the existence of a certain technique is publicly known, Exemption 7(E) will still shield documents that reveal the circumstances under which it is used, if those circumstances are not publicly known. See Blanton, 63 F. Supp. 2d at 49-50 (noting that information about polygraph tests was widely ...
