As the other reply says, it's a civil case. Preponderance of Evidence applies, which is a much, much lower bar. Think, millions of dollars awarded over coffee that was served too hot.

And, civil or criminal, if you think that sentiment doesn't come into play, then you probably think justice is blind, politicians don't lie they just over promise, and that the markets are rational. What a wonderfully, blissfully ignorant state to exist in.
