Deliberate handball -
(a) A player puts his hand deliberately in the way of the ball or
(b) A player deliberately fails to take his hand out of the way of the ball.
So ball to hand isn't a penalty, which was Mahon's point (albeit he got it the wrong way around first).
I still don't think it was a penalty. Tony was headed to the right and had his hand only very slightly out for balance (as anyone would if they're running) and the Bohs lad flicked it up. He had no chance of taking his hand out of the way, so point (b) doesn't hold, and he doesn't appear to move his hand to the ball either, so point (a) doesn't hold. There was a handball, but it was accidental, so no penalty.
