What is the significance of 'ultimate issue' opinions by lay witnesses under Rule 701?

• A. They are never admissible.
• B. They require experts.
• C. They must be based on perception and helpful, but cannot address complex ultimate legal conclusions.
• D. They can address any legal conclusion if based on perception.

Answer: (C)

Rule 701 lets lay witnesses give opinions if they are grounded in the witness’s own perception and help the jury understand the testimony or determine a fact. The important point is that these opinions can come from what the witness observed or perceived, but they must not reach into complex legal conclusions. So a lay opinion is admissible when it is based on perception and aids the fact-finder, but it should not state or resolve intricate legal standards like negligence, intent, or other legal conclusions. That distinction keeps the testimony practical and understandable while preserving the jury’s role in applying the law.
