Yeah, they've had it for a while and as long as you graduate from UW, then you're automatically admitted to the Wisconsin bar. It gets better. I dont know how true this is, but I even heard that as a member of the wisconsin bar, if you go to (I think DC), you can get a waiver just because you're already a member of another bar. (Dont chew me out, I dont know how true this is).
My guess is that with the pressure building up, they will eventually do away with it but it will include a clause and it will simply state that you're still exempt from the bar as long as you were a 1L at the time the law was repealed.
