You probably heard yesterday's good news that the ACLU prevailed in their petition for an injunction against the NSA warrentless wiretapping. (Our case against AT&T to hold them accountable for allegedly participating in this now-ruled-unlawful program continues in the courts.)
However, the ruling was appealed (no surprise) and the government also asked for, and was granted a stay of the injunction. So the wiretaps won't stop unless the appeal is won.
But this begs the question, "Why do you need a stay?"
