Rule Clarification

[Dewey1]

It is over and back.

here is a good rule of thumb to remember - "last to touch first to touch". Who was the last to touch it is the front court? In this case Team A, as it hit A1's foot. Then would was the first to touch it in the back court? Again in this case Team A. Therfore it is over and back.

If the last to touch in the front court would have been Team B then Team A could get it in the back court without a penalty.
