What are the ABC's?

I think one of the problems with type A obstruction and almost all forms of interference is that the umpire is forced to stop play and make a judgment about what would have happened. The rules rarely permit the affected side to "waive the penalty and take the play" when something unusual happens immediately after the call.

Horrah for FED in dealing with obstruction as under FED rules Obstruction is ALWAYS Type B. No forcing the umpire to make a decision here.
