Plaintiff's attorney Larry Klayman represented the subscribers of the Verizon Wireless Business Network.

According to The Washington Times, during arguments on Oct. 8 Klayman asked Leon to declare the entire USA Freedom Act unconstitutional and disband the bulk collection practice.

"Congress does not have the right to violate the Constitution," Klayman said at the time. (RELATED: Wikipedia Tells Reddit Why It Thinks It Can Win Its Lawsuit Against NSA)

During a hearing on Sept. 2, Leon told the attorneys the "clock is running and there isn't much time between now and November 29 … this court believes there are millions and millions of Americans whose constitutional rights have been and are being violated, but the window … for action is very small. … It's time to move."

According to US News, Leon is the first and only district court judge to rule against the NSA program.
