With the U.S. most likely to appeal the ruling, Judge Leon held off from banning the practice. The information collected by the NSA shows phone numbers and the elapsed time of these calls without revealing the content of them. Earlier this year, the NSA admitted to receiving metadata from companies like Verizon, Apple, Microsoft, Google, Yahoo and Facebook.
After the 9/11 terrorist attacks in the U.S., the Patriot Act was rushed through Congress and signed by President George Bush. The law allowed for the expanded reach of agencies like the NSA in the name of national security, but rulings such as the one made today by Judge Leon might be the start of reducing the expanded activities allowed under the Patriot Act.
