Today's been a fairly boring day in the California courts. I assume that's because of the heat.
But there are still lessons to be learned. For example: This, among other things, is why you need to make sure that your expert knows the underlying law. Because if s/he doesn't, then the expert's testimony might not address the relevant legal issues, and if (as here) it's off target, even a fraction, any resulting damage award may well be reversed.
Which, in this case, costs Russell Christoff over $15 million. Oops!
