Your lawyer puts something in writing, and it turns out to be totally wrong and misleading, but that is not fraud/deceit?
Do we know what Rossi's lawyer said is wrong?
We know because Rossi admitted as much. He agreed the lawyer lied, but he said -- in effect -- that one lie in one e-mail does not constitute enough deception to be considered deception. He said I.H. has to come up with more proof of deception. It is a strange argument, but that is what it boils down to.
