• D. Expert evidence must be based on personal belief.

Answer: (A)

Expert evidence is testimony or a report from someone with specialized knowledge beyond ordinary experience, used to help the decision-maker understand technical or scientific issues in a case. It is established by focusing on the use and requirements of this kind of evidence: who can be deemed an expert, what qualifications are needed, and what standards apply to the methods, data, and conclusions so the opinion is reliable and helpful. In practice, the expert must be qualified by education, training, or experience, base their opinion on appropriate and recognized methods, rely on sufficient data, and connect those findings to the facts in the case. The tribunal will consider the admissibility and weight of the evidence, allow cross-examination, and ensure the opinion actually assists in resolving the issues rather than substituting lay testimony. This is why the correct understanding centers on how expert evidence is used and what is required for it to be admissible and persuasive.
