On Friday, I heard from Jonathan Freiman, a constitutional lawyer who represents Jose Padilla in a lawsuit against the government.

By promising to improve its policy for invoking the state secrets privilege, the Obama Justice Department last week announced, with much fanfare, that it will require the attorney general to sign off every time the Justice Department claims “state secrets” trump a victim’s charges. Well, as Freiman points out, that’s what the law has always required, at least in theory. And that hasn’t stopped the government from using the state secrets privilege in the past simply to cover up government wrongdoing.

“Ever since the Supreme Court first recognized it in U.S. v. Reynolds, the doctrine has required that any invocation of the privilege be supported with an affidavit from the head of the relevant government department,” wrote Freiman in an email. “If we expect the A.G. to be more likely than other high government officials to respect law – and less likely to invoke the state secrets privilege just to cover up government wrongdoing – then the new policy is a good thing.”

“But for most of the last decade there wasn’t much reason to put the A.G. on a pedestal above his cabinet peers,” Freiman wrote. Maybe things will change, he said, but “with the administration’s continuing opposition to real checks and balances, it’s possible that we’ll never really know whether they’ve changed.”

That is, of course, the problem with allowing the government to claim “state secrets” to dismiss a case without even letting the judge review the evidence to decide if it’s really a national security concern or not. After all, in the Reynolds case, when the government first claimed the privilege, insisting that release of information about a military plane crash would endanger national security, it turned out the Justice Department was just hiding the military’s own negligence — and denying the widows of the plane crash victims not only compensation, but any opportunity to find out what really happened.

Correction: I mistakenly identified Jonathan Freiman as representing Al Haramain Islamic Foundation in a previous version of this post. He represents Jose Padilla. Jonathan Eisenberg represents Al Haramain. This post has been updated to reflect the correction.

In three particular cases — Jewel v. NSA, Al Haramain v. Obama, and Mohamed v. Jeppesen Dataplan — the administration has asked courts to dismiss the cases on the grounds that allowing them to go forward would reveal “state secrets.”

Responding to the outcry that the administration is abusing the privilege, the Senate is set to take up legislation, the State Secrets Protection Act of 2009, that would limit the executive’s ability to dismiss cases based on the privilege. Holder suggested that the Obama administration’s view of the matter will be different than the Senate’s, and will eliminate the need for the legislation altogether.

He promised to produce that new policy publicly “in a matter of days.”
