Google has filed a rare petition to challenge a national security letter issued by the government to obtain private data about one or more of its users, Wired reports.
The petition, filed under seal in the U.S. District Court of Northern California on March 29, comes mere days after a U.S. District Judge in California ruled in a case brought by an unnamed company and the Electronic Frontier Foundation that so-called NSLs that come with a gag order on the recipient are an unconstitutional impingement on free speech, the article says.
