Which statement best describes the admissibility difference between lay eyewitness and expert testimony?

• A. Lay testimony is observations by a non-expert; expert testimony relies on specialized knowledge and methods, subject to rules of admissibility.
• B. All testimony is treated the same under admissibility rules.
• C. Lay testimony must always be accompanied by expert testimony.
• D. Expert testimony is never restricted by admissibility rules.

Answer: (A)

Lay eyewitness testimony comes from someone describing what they perceived with their senses, without special training. Its admissibility is straightforward: it’s allowed if it helps the fact finder understand what happened and is based on the witness’s perceptions. Expert testimony, on the other hand, rests on specialized knowledge, techniques, and data, and it must meet stricter standards to be admissible. The expert must be qualified, and the methods used must be reliable and explained for the court to evaluate how they support the conclusions. This difference in the level of required foundation and gatekeeping behind the testimony is what the statement captures as the key distinction.
