“When you talk about fraud,” [Jina Choi of the SEC] answered, “you’re talking about a state of mind, you’re talking about mens rea. We call it scienter. You have to do something with intentionality. The idea of just making a misstatement doesn’t necessarily rise to the level of fraud."
Misstatements can “be the first step to fraud,” Choi had added. “But generally, when we talk about fraud the F word, I think we are talking about a state of mind that’s a little bit higher than that.”[1]
That telegraphs a pretty lenient stance on misstatements that aren't completely fabricated. And there were actual serious negotiations happening here. That's not in dispute.
Without question, Musk made a misstatement. But what was his state of mind? Was there intent to deceive, or was he merely overzealous in his interpretation of the negotiations? If he can argue the latter then it may not rise to the level of criminal fraud.
