What is Demonstrative Evidence?

What is Demonstrative Evidence?

• A. Evidence that proves a fact directly without inference.
• B. Used to help explain testimonial evidence (diagrams, charts, graphs, models, etc.)
• C. Circumstantial evidence.
• D. Evidence used to impeach a witness.

Answer: (B)

Demonstrative evidence are visual or physical aids used to illustrate and clarify what a witness testifies about, helping the jury understand the testimony. These tools—diagrams, charts, graphs, models, photographs, maps, and similar items—do not prove a fact by themselves; they explain or illuminate the information given by a witness. That’s why this type of evidence is described as explaining testimonial evidence. Direct evidence proves a fact directly without needing inference, while circumstantial evidence requires the jury to infer a fact from other evidence. Impeachment evidence is used to challenge a witness’s credibility, not to illustrate or explain testimony. Demonstrative evidence must be relevant and properly authenticated and should aid understanding without misrepresenting the facts.
