legal or illegal

[xxssmen]

I had a debate with a fellow rec. league official about whether it is legal to be the first one to touch the ball after saving it from going out of bound.
I say it is legal as long as u establish ur self back on the court, he say no that its illegal a player who goes out of bound cannot be the first one to touch the ball.

Can u tell me where in the rule book I can find the answer to this debate?
