What does Federal Rule 1006 allow concerning voluminous writings?

Federal Rule 1006 is designed to address the presentation of voluminous writings in a manner that makes them accessible and understandable to the court and the jury. The rule specifically allows for the presentation of summaries, charts, or calculations that are based on the contents of voluminous records, as long as those original documents are available for examination by the opposing party.

In this context, the correct understanding of the rule is that when a party has a large amount of data, they may use charts or summaries to present that information more clearly, provided that the original documents are accessible to be reviewed if needed. This ensures that while the information is simplified for clarity during the trial, there remains transparency because all original records are still available for scrutiny.

The other options do not accurately capture the stipulations of Federal Rule 1006. Summarizing documents without originals being available does not comply with the rule's requirements, and neither does the exclusion of documents or a purely oral presentation of the materials without documentation meet the criteria outlined in Rule 1006. The essence of the rule is to facilitate the use of voluminous materials while maintaining access to the original documents for verification and examination purposes.
