The lawsuit is based largely on Klein’s documents, in which he and EFF assert that the NSA is capable of monitoring communications on AT&T’s network after the NSA installed equipment in secret rooms at AT&T offices. AT&T claims the documents involve trade secrets, and it has “an obligation to assist law enforcement and other government agencies responsible for protecting the public welfare.”160Want local news?Sign up for the Localist and stay informed Something went wrong.

The goal of the lawsuit is to dismantle warrantless eavesdropping on Americans in the United States, a practice the Bush administration confirmed in December. EFF’s case would have been weakened if the records provided by the whistle-blower were taken from the case. “I believe I have significant information to bring to the table,” the former technician, Mark Klein, told reporters after the 90-minute hearing. SAN FRANCISCO – Secret documents allegedly detailing surveillance of AT&T Inc. phone and e-mail lines under the Bush administration’s domestic spying program can be used in a lawsuit against the telephone giant, a federal judge ruled Wednesday, but the records will remain sealed. U.S. District Judge Vaughn Walker rejected a bid by AT&T to return the records given to the privacy advocate Electronic Frontier Foundation by a former AT&T technician. But Walker said the records would remain under seal until it can be determined whether they reveal trade secrets. “The best course of action is to preserve the status quo,” Walker said. The hearing is the first in a lawsuit challenging the administration’s secretive domestic surveillance program.
