""It's an important first step, since telcos historically haven't done much to resist lax surveillance procedures," Jonathan Mayer, a privacy technologist and lawyer and a fellow at Stanford University, told Mashable.

Mayer noted that all the arguments laid down in the brief are taken from previous opinions from other courts, and AT&T doesn't really take its own position. "They certainly aren't demanding warrants," he said."
