Judge Anna Diggs Taylor’s ruling was in response to an ACLU lawsuit.
She said the taps violate free speech and privacy rights. I’m not so sure about the free speech argument. The privacy argument is stronger, though a lot of people argue that the idea of a right to privacy is a myth.
In any case, this bumps the pressure on the government up several notches. I presume the government will appeal the decision, which could lead to a Supreme Court ruling depending on what the appeals court does.
The Detroit Free Press has a bio of the judge.
