There are two parties concerned with the performance of experts: the party that hires the expert to testify and the opposing party. Their goals are at odds. The hiring party wants effective testimony as measured by a beneficial effect on the judge and jury, while the opposing party wants the expert discredited and the testimony stricken. Dissatisfaction by either party, without more, is not evidence of malpractice. As in other malpractice actions, it must be found that the expert performed below the standard for the profession he/she represents, and that this substandard behavior caused the party's injuries. Thus the party claiming malpractice must show both the standard for such experts and that, but for the expert's deviation from the standard, the party would have won. However, unlike other malpracticing professionals, the expert witness occupies a privileged place in the legal system.
