In today’s fast-paced world, succinct and impactful communication of the most relevant evidence is vital in a jury trial. Demonstrative evidence is a necessary tool in the presentation of evidence in a way that both effectively educates and holds the attention of the jury. Charts, maps, timelines, photographs, lists, videos, diagrams, models, documents, and animations are all common types of demonstrative evidence.
Demonstrative evidence can be thought of as an exhibit used to illustrate evidence, while documentary evidence is an exhibit used as evidence of a fact. Demonstrative evidence is admissible for the purposes of illustrating and clarifying a witness’ testimony. Trial judges have wide discretion in admitting demonstrative evidence.
Some types of demonstrative evidence may be permitted by the trial judge for the purpose of assisting jurors in understanding testimony, such as a writing out a chart of adjectives used by the witness. However, if demonstrative evidence is in any way testimonial, proper foundation must be laid for the use of that evidence.
Counsel may be permitted to question a witness regarding demonstrative evidence, such as during crossexamination, without offering it as evidence.
Demonstrative evidence is useful in all different types of cases and the creative possibilities are endless. From skeleton models and animations of surgeries, to a simple butcher paper list of injuries listed by plaintiff during her testimony, demonstrative evidence can be as complex or as simplistic as you are comfortable with.
It is important that every piece of demonstrative evidence you intend to show to a jury is well thought out, examined for potential use in cross-examination, and tested by the trial attorney who will be utilizing the exhibit. Our top ten tips for impactful use of demonstrative evidence include:
