Ball coming back

The ball is hit over the net but bounces back to your side with enough spin.

I saw one game where a person put a lot of back spin on the ball that when it hit the opponents side it bounced to his side without the opponent hitting it.

So who's point is it? 

Hi Bill,

That would be the point of the player that hit the ball with backspin.  His opponent would have to hit the ball before it bounced back.
