Unless it's an executive pardon or a statement from the attorney general exempting Snowden from prosecution this isn't a win for Snowden.
In any case there might be an interesting development as it might turn into a catch 22 for the NSA if they'll claim that it's technically unfeasible for them to filter out their collection based solely on specific individuals/organizations (which is probably technically correct) it can open a whole new can worms for them (since they've claimed that the collection is targeted and ensures that certain parameters are met (other than it's a phone call, email, skype call or 1 or more person(s) talking in range of a microphone they can jack into)). If they'll find a way to comply well they might be flooded by similar law suits, and even FOIA requests from individuals and organizations about if and when any data about them was collected.
On the other side of the coin this might come to bite us in the arse if the NSA makes a case that to comply with this ruling they'll have to perform in-depth analysis of every communication they collect to ensure that no phone call data is being collected which might involve J.J. Little, especially if VOIP communications fall under this jurisdiction and ofc they can later claim that any intelligence gathered from that analysis is lawful and actionable/admissible because it was gathered in the course of achieving compliance with a court order.
Dear Citizens,
In order to comply with Civil Action No. 13-851 Klayman et al. v Obama et al. we now need to transcribe all domestic and international calls conducted from and to the continental united states, the pacific states as well as any incorporated and unincorporated territories and any commercial fleet vessels sailing under the US flag in order to ensure that the call does not contain any information, data or reference to J.J. Little & Associates, P.C. or it's clients.
Sincerely the NSA.
