What steps should be taken when introducing demonstrative evidence to ensure admissibility?

• A. Present without foundation
• B. Ensure relevance and authentication, lay a proper foundation, avoid misrepresentation, and provide copies or explanations to the court and opposing counsel
• C. Only show to the judge
• D. Copy must be identical to source

Answer: (B)

Admissibility for demonstrative evidence hinges on making it useful and trustworthy through a proper foundation. Start with relevance—the item must relate to a fact at issue and help the fact-finder understand the testimony. Then address authentication: show the demonstrative actually represents what it’s intended to illustrate, tying it to a source, method, or process, and to the witness or evidence it’s based on. Once relevance and authenticity are established, lay a complete foundation: explain how the item was created, how it will be used in court, and any steps taken to ensure accuracy. This prevents the jury from being misled and gives the court a clear basis to admit it. Avoiding misrepresentation is essential. Present the demonstrative in a way that accurately reflects the underlying facts, including any limitations, scales, or margins of error, and disclose any edits or alterations. That honesty protects the integrity of the evidence and helps the opposing side assess its impact. Providing copies or explanations to the court and opposing counsel ensures fairness and allows for review, objections, or cross-examination if needed. It helps prevent surprise and supports a proper ruling on admissibility. Choices that advocate presenting without foundation, restricting viewing to the judge, or insisting that copies must be identical miss key elements—relevance, authentication, full foundation, and fairness in disclosure—that determine whether demonstrative evidence can be admitted and used effectively.
