3.17 Demonstrative Summaries/Charts Not Received in Evidence is a type of evidence that is not allowed to be presented in a court of law. This type of evidence includes charts, diagrams, summaries, and other demonstrative materials that are not officially part of the trial record. Examples of this type of evidence can include a witness’s summary of a conversation, a chart of financial records, or a diagram of an accident scene. This type of evidence is not received in evidence because it is not considered reliable or trustworthy enough for the court to consider as part of the trial.
