You might, as I do, prefer written sources, but I must recommend watching (even just the first part of) this BBC documentary. https://www.youtube.com/watch?v=vDADy9b2IBM
also 31:40 "All the changes we made to the structure of Serbia were implemented using perfectly legal means. We followed the proper procedure."

This was a BBC production, so we expect to see the NATO side, but given that Milošević's lawyer had a fool for a client, I am not feeling poorly at being inclined to their editorial.
