United States District Court Judge Richard Leon ruled the National Security Agency's collection of civilian phone records is unconstitutional during the first hearing held on Monday, the Associated Press reported.

Larry Klayman and Charles Strange are two American lawyers who won a preliminary injunction against the NSA spying procedures brought to light by ex-NSA employee Edward Snowden, according to the AP.

Judge Leon put a hold on his decision to allow the U.S. government to appeal, though the ruling indicates Klayman and Strange's claim that American's constitutional rights are being trampled is likely to be given a win, the AP reported.

Leon added that a program used to collect massive amounts of information is an "unreasonable search" under the Fourth Amendment.

Leon called the technology used by the NSA in its "counterterrorism" spying programs as "almost-Orwellian" adding that they are based on a Supreme Court precedent which states: "Americans had no privacy interest to keep the government from accessing records stored by phone companies," according to NBC News.

"The relationship between the police and the phone company is nothing compared to the relationship that has apparently evolved over the last seven years between the government and telecom companies," Leon said, according to NBC.

According to Leon, who was appointed by former President George W. Bush, the two lawyers should have no issues in proving that their privacy interests will outweigh the NSA interests in the data collecting procedure, according to the AP.

Though the White House and the Obama administration relentlessly defend the program as a crucial tool in fighting terrorism, Leon, in a 68-page document on the case, said there is not one piece of evidence to cite an instance where the NSA spying "actually stopped an imminent terrorist attack," the AP reported.

"I have serious doubts about the efficacy of the metadata collection program as a means of conducting time-sensitive investigations in cases involving imminent threats of terrorism," Leo stated, according to the AP.
