What is admissible in place of originals if they are too voluminous?

When evaluating what can serve as admissible substitutes for original documents when they are too voluminous, the use of summaries, charts, or calculations is entirely appropriate under the rules of evidence. The intention behind allowing these substitutes is to present a more manageable and comprehensible version of extensive information contained in a large volume of documents.

Summaries, charts, or calculations can provide a concise representation of the data while maintaining the integrity of the information contained in the originals. This is particularly helpful in court, where time constraints and the need for clarity can be challenging, allowing judges and juries to grasp essential aspects of voluminous evidence without wading through extensive and possibly tedious original documents.

In contrast, while legal briefs, compendiums of related documents, and witness testimonies may serve various evidentiary purposes, they do not specifically function as admissible substitutes for original documents under this context in evidence law regarding voluminous records. Summaries, charts, and calculations are explicitly designed to facilitate understanding without losing the relevant facts and are hence the best answer in this scenario.
