@digitall1,
Luongo was certainly a dispute, and this is, of course, gossip -- he was caught sleeping with Robert Bane's wife and shortly after, they parted company. The art business is just as "Peyton Place" as the movie business, or the TV business or any of those entertainments! They just love entertainment, decadent or otherwise.
I do not know in what court Earle lost his case to Bane, and Earle was so adverse with the judge that it was easy to merely enforce the original contract and Earle lost the case. Legal advice has to come from an attorney but whatever fraud is alleged, it's likely true but hard to prove. Bane is a slick customer and artists are lousy business people , and, unfortunately, get suckered into signing contracts where they don't read the fine print and do not give it to their attorney to look at. Of course, there's been several artists who bilked the public big time on their own and don't seem to possess even the moral and ethics of a politician. I won't mention any names, but if by telepathy this gets transmitted, Thomas Kinkaid (the most notorious rip-off hack artist of all times). That's not to say there aren't honest people in the art business but they are constantly plagued by the fact that too much of the public knows nothing about art and can be sold anything. It's too bad the artists aren't smarter, but they seldom are.
It's a tough business and I suggest a suit of armor.
