Further to Xeni's post from yesterday about the landmark ruling by a San Francisco district court judge that the FBI may not issue "national security letters" (NSLs), the Electronic Frontier Foundation, who fought the case, has posted a good explanation about what NSLs are and why they were so creepy:

The controversial NSL provisions EFF challenged on behalf of the unnamed client allow the FBI to issue administrative letters — on its own authority and without court approval — to telecommunications companies demanding information about their customers. The controversial provisions also permit the FBI to permanently gag service providers from revealing anything about the NSLs, including the fact that a demand was made, which prevents providers from notifying either their customers or the public. The limited judicial review provisions essentially write the courts out of the process.

In today's ruling, the court held that the gag order provisions of the statute violate the First Amendment and that the review procedures violate separation of powers. Because those provisions were not separable from the rest of the statute, the court declared the entire statute unconstitutional. In addressing the concerns of the service provider, the court noted: "Petitioner was adamant about its desire to speak publicly about the fact that it received the NSL at issue to further inform the ongoing public debate."

"The First Amendment prevents the government from silencing people and stopping them from criticizing its use of executive surveillance power," said EFF Legal Director Cindy Cohn. "The NSL statute has long been a concern of many Americans, and this small step should help restore balance between liberty and security."
