As I understand it....
#1 - Yes, Baez can object and appears to have done so in the response filed today (see separate thread)
#2 - If JS decides to deny the SA motion ("I'm not going to grant this meeting), then yes, the SA will have to release this information in a timely manner to the defense, and when that happens, we will eventually see it, thanks to the Sunshine Law. (either way, we will eventually see it as it is discoverable materials)
#3 - I don't think JS denying defense on previous ex-parte requests will have any bearing on whether he grants this motion of SA or not. JS seems to be a pretty straighforward, by the book kinda guy (who sits on rainbows :dance
