Access Wisconsin Lawsuit: Today's Discovery @ Wisconsin Circuit Court Access

While doing my deep dive through the "Recent Developments" section of Bob Bocher's background paper, I doubled-checked Judge Peter C. Anderson's court calendar and didn't find a listing for an August 30th injunction hearing.

Searching by case number, I learned that motion hearings have been scheduled on Thursday, September 15, and Wednesday, September 28.

Attempting to learn exactly what this means.  (Everything I know -- or think I know -- about legal procedures comes from TV and movies.)  Please share if you have any information.
