The Obama Administration is preparing to announce a new policy that would limit the use of the state secrets privilege, according to reports in the New York Times and Washington Post. The policy will take effect October 1. From the Post:

The new policy requires agencies, including the intelligence community and the military, to convince the attorney general and a team of Justice Department lawyers that the release of sensitive information would present significant harm to "national defense or foreign relations." In the past, the claim that state secrets were at risk could be invoked with the approval of one official and by meeting a lower standard of proof that disclosure would be harmful.

Under the new policy, if an agency like the National Security Agency or the Central Intelligence Agency wanted to block evidence or a lawsuit on state secrets grounds, it would present an evidentiary memorandum describing its reasons to the assistant attorney general for the division handling the lawsuit in question.

If that official recommended approving the request, it would be sent on to a review committee made up of high-level Justice Department officials, and then to Deputy Attorney General David W. Ogden and Mr. Holder. All those officials would be charged with deciding whether the disclosure of information would risk "significant harm" to national security, and they would be instructed to seek a way to avoid shutting down the entire lawsuit if possible.

If the Justice Department signed off on asserting the privilege, the head of the agency controlling the information would sign a classified memorandum to be filed with a court explaining in detail the government's reasoning. A judge could request access to particular pieces of underlying evidence.

The policy is silent on whether the government would comply, and officials said such requests would be evaluated on a case-by-case basis. One of the controversies surrounding the privilege is that sometimes judges accept executive assertions about classified evidence without independently examining it.

The new policy would also direct the Justice Department to reject a request to use the privilege if officials decide the motivation for doing so is to "conceal violations of the law, inefficiency or administrative error" or to "prevent embarrassment."

This change may have been a long time coming, but that is not a surprise. Federal policies of this sort cannot be changed overnight -- at least not without substantial cost. Specific policy guidelines and supporting memoranda must be drafted and approved after input from affected agencies. This can be a lengthy process, particularly when key offices in the relevant agency are vacant and the Administration has other pressing priorities on its plate. While I suppose the President could have immediately suspended reliance on the privilege, he took a more responsible course: ordering a review of how the privilege is used and tasking Justice Department attorneys with developing a new policy that will safeguard vital government interests in a less intrusive fashion.

Based on these news reports, it sounds like the new policy is a significant improvement. The state secrets privilege should be used quite sparingly, and only then as a last resort. It should not be a ready tool to make embarrassing or inconvenient litigation go away. Developing more formal guidelines is also an improvement, as the lack of clear rules makes it easier to invoke the privilege unnecessarily. It is only natural for government attorneys to seek any and all means of dismissing unwanted litigation -- after all, their goal is win for their client (which, for most governemnt attorneys, is the government). Therefore, clear rules and procedures limiting the privilege will reduce this potential for abuse. Even if the new policy would have allowed invocation of the privilege in the recent cases that sparked the controversy, it should provide greater assurance that the privilege is only invoked when it serves a legitimate purpose.
