Oksana's Lawyer: Mel Made Money from the Mediation!

How's this for an argument ... Mel Gibson was the opposite of an extortion victim during his mediation with Oksana Grigorieva.  Mel actually made money off the mediation ... according to legal docs filed by Oksana's lawyer and obtained by TMZ.

Oksana's lawyer, Daniel Horowitz, filed a declaration in the search warrant motion, stating, "Mel Gibson received a substantial financial benefit from the [mediation] agreement."

So how did Horowitz reach his conclusion?  He says the actual value of the mediation deal for Oksana was somewhere between $1.2 and $2 million -- not $15 million.

And, Horowitz says, Mel got a sweet financial deal by only giving Lucia $10 million under the mediation deal.  Horowitz says Lucia was actually entitled to 1/8 of Mel Gibson's trust -- money she would share with Mel's other 7 children.  But under the mediation, Oksana gave up Lucia's rights under the trust, which Horowitz says would have given her way more money than the $10 mil.

So his point -- How can you be an extortion victim when you make money?
