Witnesses

An expert witness is a person who, by reason of education or specialized experience, is allowed to testify at a trial not just about the facts of the case but also about the professional conclusions he draws from the facts. Medical, scientific, and technical experts are commonly used, but other types of experts can be used. For example, in an employment discrimination case, an economist might serve as an expert witness, providing professional testimony about discriminatory wage patterns in the affected industry. Experts witnesses generally charge a fee for their services.
