FILE - This June 6, 2013 file photo shows a sign outside the National Security Administration (NSA) campus in Fort Meade, Md. Massive government surveillance of Americans' phone and internet activity is drawing protests from civil liberties groups, but major legal obstacles stand in the way of any full-blown court hearing on the practice.

The Supreme Court, where several justices have written about complex issues of privacy in the digital age, could be the ultimate stop for such lawsuits. (AP Photo/Patrick Semansky, File) less
