New Limitations on Tolling the FOIA's Response Time
Section 6 of the OPEN Government Act of 2007, Pub. L. No. 110-175, 121 Stat. 2524, imposes several new requirements on agencies that impact the time limits for complying with FOIA requests and impose consequences on agencies when those time limits are not met. This section took effect on December 31, 2008, and applied to FOIA requests "filed on or after that effective date." § 6(b)(2). Accordingly, beginning with requests received on December 31, 2008, agency FOIA offices will: 1) be required to forward any misdirected FOIA requests received by them to the proper FOIA office within the agency, within ten working days; 2), be limited in the number of times they can "toll" the twenty-working day response period; and 3) be precluded from assessing search (or if applicable, duplication) fees if they are unable to comply with the FOIA's response times, unless the exceptions to this limitation are met.
