The lawsuit is to get the 10 million dollar fee, since Wang apparently isn't paying it.
The events so far for clarification:
Barroway and Wang come to an agreement on a sale, verbal and with a handshake.
Both agree on a the 10 million dollar fee against either side if one decides to back out.
After the Clippers are sold, Wang has second thoughts on the sale price.
Wang then either sells to someone else instead or lies about selling to someone else, and tells Barroway that he's already sold to someone else at a higher price.
Barroway is now going to sue Wang for that 10 million dollar fee they agreed on.
Am I missing anything anyone?
I don't think so.
This is similar to someone selling a house, taking a deposit from a buyer, then learns the next day that the municipality is buying up all the land surrounding the house and paying 3 times more than the selling price the seller agreed to and backs out of the original deal.
