What is Opinion Testimony? A Comprehensive Legal Overview
Definition & Meaning
Opinion testimony refers to statements made by a witness based on their beliefs or interpretations rather than direct knowledge of the facts involved in a case. Generally, opinion testimony is not allowed in court unless specific exceptions apply. Both lay witnesses (those without specialized knowledge) and expert witnesses (those with relevant expertise) may provide opinion testimony under certain conditions, as outlined by legal standards.
