Way, way behind on this story, but here’s the original EFF press release on the topic, and Wired just posted all the documents from EFF’s primary witness:
The documents, available on Wired News as of Monday, consist of 30 pages, with an affidavit attributed to Klein, eight pages of AT&T documents marked "proprietary," and several pages of news clippings and other public information related to government-surveillance issues.
The AT&T documents appear to be excerpted from material that was later filed in the lawsuit under seal. But we can’t be entirely sure, because the protective order prevents us from comparing the two sets of documents.
The court’s gag order is very specific in barring only the EFF, its representatives and its technical experts from discussing and disseminating this information. The court explicitly rejected AT&T’s motion to include Klein in the gag order and declined AT&T’s request to force the EFF to return the documents.
