the notion that two rules may apply simultaneously. In any logical system, snotty or not, there will be meta-rules.

"Oh, wait, I get it. No, A3 doesn't cause it to go into the backcourt. When he first touches it, if his feet were last in the backcourt, then he doesn't cause it. The last player to touch in the front court is the one who "causes it to go into the back court."

I like this. I tend to agree with it. If you take 'causes' to mean 'propels'. But this is a little unusual. Usually one causes the ball to be somewhere by virtue of touching it.
