does anybody out there know

how many Patriot Act abuse cases the aclu has taken to court since the inception of the act? i can't seem to find any new information about that. i remember a couple of months ago there was an op-ed that i read but i can't find it either. in the op-ed, the writer stated that to date, the aclu had not taken one single abuse case to court. i'm wondering if that's true, and if it's still valid. any suggestions?
