What is demonstrative evidence?

Demonstrative evidence is a type of evidence that helps illustrate or clarify a witness's testimony or a particular fact in a legal case. It is used to visually demonstrate or explain complex or technical information to judges and juries in a way that is clear and easy to understand.

Examples of demonstrative evidence include charts, graphs, diagrams, photos, maps, models, videos, and computer animations. These visual aids can help convey information more effectively than verbal descriptions alone, making it easier for the trier of fact to comprehend and remember key details of a case.

Demonstrative evidence is not considered substantive evidence by itself, meaning it cannot be used as direct proof of a fact. It is meant to supplement and support other forms of evidence, such as witness testimony or physical evidence. However, it can play a crucial role in helping the fact-finder reach a decision in a case by providing context and perspective on the evidence presented.

Overall, demonstrative evidence is a valuable tool in the courtroom that can enhance the presentation of evidence and improve the understanding of complex issues for judges and juries.
