Throw from F2 hits batter's bat on backswing - Call?

As Celil One says, there is a lot of ambiguity and contradiction here and since I've been to three national clinics in the last 10 years, 2 in Ohio and one in Pennsylvania, and numerous local clinics, attending the clinics isnt the issue. These clinics were led by some of the 'biggest' names in ASA (USA) and even the big names couldn't agree on some of the rules, interpretations or mechanics. Finally, even on this forum a few of the 'respected' opinions cant agree and have even given conflicting information making it quite clear that there is a lot of confusion on the subject from pretty much the top down. I would say given that many more umpires read case plays, rule books and the rules and clarifications section on the website than attend national clinics and/or perhaps local clinics, i would respectfully disagree that formulating a case play, posting in rules and clarifications or augmenting the language in the rule book wouldn't be helpful
