What role do expert witnesses fulfill during trials?

Expert witnesses play a crucial role in trials by providing specialized knowledge or opinions that are relevant to the case being examined. Their input helps the court to understand complex scientific, technical, or professional subjects that are beyond the general knowledge of the judge and jury. For instance, in a medical malpractice case, a doctor may serve as an expert witness to explain whether the medical care provided met the accepted standards.

Expert witnesses are typically called upon to clarify evidence, assess the validity of claims made by the parties involved, and support the facts with their expert opinions. Their credibility and authority can greatly influence the outcome of a case, as their testimonies can lend significant weight to the arguments of one side or the other.

This function of providing specialized knowledge distinguishes them from legal advisors, who may assist in the legal strategy but do not provide testimony in the courtroom. Similarly, they are not advocates for any party, including victims, nor do they engage in the conduct of trial proceedings, which are the responsibilities of judges and attorneys. Their primary aim is to enhance the court's understanding of complex issues to ensure a fair adjudication process.
