The Justice Department has proposed the change as part of a large revision of FOIA rules for federal agencies. Specifically, the rule would direct government agencies who are denying a request under an established FOIA exemption to “respond to the request as if the excluded records did not exist,” rather than citing the relevant exemption.

The proposed rule has alarmed government transparency advocates across the political spectrum, who’ve called it “Orwellian” and say it will “twist” public access to government.

In a public comment regarding the rule change, the ACLU, along with Citizens for Responsibility and Ethics in Washington (CREW) and OpenTheGovernment.org, said the move “will dramatically undermine government integrity by allowing a law designed to provide public access to government information to be twisted to permit federal law enforcement agencies to actively lie to the American people.”
