Could somebody explain the Motion to Quash who has an understanding of it? I thought it only applied to a subpoena, and so would not apply without one.

I don't have a full understanding of it, but I think a Motion to Quash basically asks the court to say "This information was collected illegally or outside the investigative scope, and you may not use it as evidence (and thus must destroy it)"

It seems like the distinction that the NSA is trying to make is that, it's not illegal to possess the data, only to look at it. That argument may even extend to automatic processes that aren't seen by human eyes, who knows. If you happen to get a warrant in the future, you'll be able to "travel back in time" to see all communications of the person in question. The most maddening part of all this is that no one outside the government is even allowed to know the rules.

Correct that this appears to be their argument, but that argument holds not a chance. Imagine if police searched houses randomly but "weren't allowed to use what they found unless they got a warrant." I believe this argument will be squarely and unanimously rejected by SCOTUS.

> Imagine if police searched houses randomly but "weren't allowed to use what they found unless they got a warrant."

The main remedy for illegal police searches is exclusion of the evidence if, and when, the government attempts to use it in court (and then, usually, only if they attempt to use it against the specific person whose rights were violated by the search, and not always even then [e.g., good faith exception, and other exceptions to the exclusionary rule].)

That's the main remedy in criminal court. If the police unlawfully search your house, you can also sue them in civil court for both money and injunctive relief.

It would be more like if robots searched your house and no human was allowed to look at what they collected without a warrant.

The closest ruling I can find on something like that is that sending drug sniffing dogs into a house without a warrant is illegal: http://www.huffingtonpost.com/2013/03/26/drug-sniffing-dogs-...

It would be like if dogs sniffed your house, and their reaction was recorded, but not seen by anyone. And the recording could only be viewed after a warrant was obtained. The NSAs argument is that you can't become a suspect as a result of the recording. You have to become a suspect in some other way, and then they can go back and analyze the recordings.

Exactly... to "quash" literally means to set aside. You're asking them to undo something they've done, which is typical for a subpoena that was incorrectly issued.
