From National Security Archive:
Washington, DC, Decmber 4, 2012 – A government-wide Freedom of Information Act audit by the National Security Archive has found that sixty-two out of ninety-nine government agencies have not updated their FOIA regulations since US Attorney General Eric Holder issued his March 19, 2009 FOIA memorandum to all heads of executive departments instructing them to make discretionary FOIA releases of documents that might be technically exempt from release (especially with respect to the "deliberative" b(5) exemption), to proactively post records of interest to the public, and to remove "unnecessary bureaucratic hurdles."Fifty-six agencies have not updated their Freedom of Information Act regulations since the passage of the OPEN Government Act of 2007, which mandated that agencies reform their fee structures, institute request tracking numbers, publish specific data on their FOIA output, and cooperate with the new FOIA mediators at the Office of Government Information Services.[…]"Outdated agency regulations really mean there's an opportunity here for a second-term Obama to standardize best practices and bring all the agencies up to his day-one openness pledge," said Tom Blanton, director of the National Security Archive.
