There should of course be no "other side", as all expert witnesses have a duty to the court, rather than their client. Judging by some reports I have been sent in the past, some other "experts" are not as clear on this as I am. I imagine that those who write partial reports must dread a court appearance, when their presentation of what is at best dodgy minority opinion as consensus opinion, or even fact will be exposed.
That said, one of the court cases which were pending has just been settled out of court on the basis of my report, to the complete satisfaction my my client. When you are right, you are right.
