To: All Divisions From: OGC Re: , 03/9/2006 4. The Assistant Directors and all Deputy Assistant Directors of the Counterterrorism, Counterintelligence,* and Cyber Divisions;® 5. The General Counsel] and Deputy General Counsel for the National Security Law Branch;' 6. The Assistant Director in Charge, and all SACs of the New York, Washington D.C., and Los Angeles field offices; and 7. The SACS in all other field divisions. The NSLB is hereby authorized to issuance guidance with respect to the revision of the national security letter statutes, as well as the other changes encompassed by the USAPA IRA. One point should be made here, however. The signature authority, the initial non-disclosure certification authority, and the non- disclosure recertification authority are séparate authorities. Because an NSL warrants signature does not necessarily mean that it warrants inclusion of a non-disclosure provision. Because an NSL once warranted a non-disclosure provision does not mean that one year later, it continues to warrant a non-disclosure provision. Such certifications should not and may not be made in a perfunctory manner. There must be an assessment by the individual who signs the NSL that there is a genuine need for non-disclosure because one of the enumerated dangers may arise from disclosure. > The Counterintelligence Division was denoted in its previous signature delegation by its prior incarnation, as the National Security Division. See 66F- HO-A1255972, Serial 15. This delegation brings its designation terminology up to date. *while Counterintelligence Division and Cyber Division personnel are being given signature and non-disclosure certification and recertification authority for all NSLs, it is expected that they would rarely exercise that authority in the case of 1681lv NSLs (which signature authority they have not had to date}, which are limited to usé in international terrorism investigations. It is possible, although not likely to be a frequent occurrence, that a counterintelligence or Cyber case may have an international terrorism aspect to it that would justify the issuance of a 168iv NSL. the Deputy General Counsel for the National Security Law Branch was denoted in its previous signature delegation by its prior incarnation, as Deputy General Counsel for National Security Affairs. See 66F-HQ~Al255972, Serials 15, 31. This delegation brings its designation terminology up to date, 4
