If an exhibit is presented through the testimony of a knowledgeable witness, what is required of that testimony?

• A. It must be notarized.
• B. It must be recorded in a separate log.
• C. It must abide by all other Simplified Rules of Evidence.
• D. It must be cross-examined by opposing counsel.

Answer: (C)

When a knowledgeable witness presents an exhibit, the testimony must still satisfy all the other Simplified Rules of Evidence. The witness’s explanation or identity of the exhibit helps lay the foundation, but it doesn’t bypass rules like authentication or identification, relevance, and any applicable hearsay limitations. The exhibit is admitted only if those standards are met, just as with any other piece of evidence. Notarization of the testimony or a separate log isn’t a general requirement, and while opposing counsel may cross-examine the witness, that doesn’t substitute for complying with the full set of rules.
