Mel Gibson ex wife Oksana being sued

Oksana sued Mel and her lawyer, Eric George secured her a $15 million settlement. Oksana changed her mind and disavowed the suit.

Lawyers get paid a percentage of the compensation. In this case the amount is 10% or $1.5 million for George's law firm.

Now Oksana has refused to pay George. She is trying to get his claim dismissed. It gets worse in that there are possible extortion charges being filed against Oksana. These charges are based on her using audio tapes in order to force the settlement.

Does not a woman have a right to change her mind?
