The goal of the medical expert assessment is not treatment but guide the development of a decision about contentious claims. An offense against the evidence "assessment' during a lawsuit sometimes becomes a personal offense against the expert witness himself Regarding his response, he has to take into account that the expert witness as well as the judge may be refused due to bias, and to avoid the impression of prejudice especially in cases of medical liability.
