Which statement best describes lay witness testimony about a person’s mental state?

• A. A Lay Witness May Testify About Perceptions and Facts Observed
• B. A Lay Witness May Testify About Opinions Based On Specialized Knowledge
• C. A Lay Witness May Offer Expert Opinions
• D. A Lay Witness May Present Hearsay As Truth

Answer: (A)

Lay witnesses testify to what they directly perceived and the facts they observed. They may also offer opinions, but only those opinions that are rationally based on what they perceived and helpful to understanding the case. When describing a person’s mental state, a lay witness can say how the person appeared or behaved based on what was seen or heard, such as “he seemed angry” or “she looked frightened,” because these are inferences grounded in the witness’s observation rather than expert analysis. Opinions that rely on specialized knowledge or expertise are not allowed from a lay witness and would instead be the domain of an expert. Likewise, a lay witness cannot present hearsay as truth. So describing perceptions and observed facts about someone’s mental state is the proper role of a lay witness.
