The Electronic Frontier Foundation filed a lawsuit challenging the NSLs as unconstitutional in 2011, well before the Snowden disclosures about widespread surveillance. Their two clients are unnamed, but one is a telecom company and one is an Internet company. The two "service providers" want to speak out about the fact that they received letters, but can't. In April of last year, they won a stunning victory, when US District Judge Susan Ilston agreed with EFF that the letters are unconstitutional. The gag order stopping EFF's clients from discussing "controversial government powers" violates the First Amendment, Ilston ruled.
