The ACLU and the U.S. government faced off in federal court Friday over the constitutionality of the government’s surveillance programs.
The surveillance program at the heart of the case is the government’s use of Section 215 of the Patriot Act to collect of data about all U.S. phone calls.
The civil liberties group said Thursday that it would “argue that the mass call-tracking program violates Americans' constitutional rights of privacy, free speech, and association, and that it goes far beyond what Section 215 authorizes.”
Stuart Delery, an attorney for the Department of Justice, defended the value and legality of the mass phone data collection, saying it is “authorized by statute, and it's constitutional,” according to a Reuters report.
ACLU Deputy Legal Director Jameel Jaffer challenged the authorization of the program.
"If you accept the government's argument, you are accepting a dramatic expansion in the government's investigative power," he said.
According to The Associated Press, the judge pressed Delery on what information Congress had about the phone data collection program when it reauthorized the Patriot Act.
"The record establishes that oversight committees of both houses were briefed," Delery said.
According to Reuters, Pauley did not indicate when he would rule on the case.
