Probably only if he fucks Barb again, unless the dismissal is without prejudice. The autism deferral requires a factual finding by the court and an admission by the defendant that the facts of the case would support a finding of guilty. That, to me, seems to indicate a final adjudication, so a dismissal would probably be with prejudice. I haven't found a specific source on it and this specific statute (if it is the one they used on Chris) doesn't specify.
I'm not sure what liberties the prosecution has under this statute to stipulate prejudice, so this is more a guess based on other similar statutes than anything specific about this relatively new statute without much case law on it.
Could "IT" stand for information technology? Like maybe they seized something as evidence and are now returning it since the case is over?
