Twitter shares fall as Elon Musk backs out of deal
John Coffee, a Colombia Law School professor and a former adviser to the New York Stock Exchange and Nasdaq, told the BBC that Mr Musk didn't have a "great legal argument".
"It'll be a big battle, but I would predict it'll be quietly settled," he said. "I think Mr Musk doesn't expect to come out with a victory. I expect that he's hoping that he can knock another 10 or 20 billion off the price he agreed to pay."
