Moral Turpitude Issue: the law is unyielding

 SC:One who losses his money or property by knowingly engaging in a contract or transaction which involves his own moral turpitude may not maintain an action for his losses. To him who moves in deliberation and premeditation, the law is unyielding.  The law will not aid either party to an illegal contract or agreement; it leaves the parties where it finds them.
