Does the rule of completeness allow one side to introduce additional documents during a trial?

The rule of completeness allows a party to introduce additional evidence or documents to provide context and clarify existing evidence that has been presented. This rule is particularly relevant when a party introduces a portion of a document or an incomplete statement; the opposing party may then utilize the rule to present the omitted parts that are necessary to ensure that the evidence doesn't mislead or distort the understanding of the case as presented.

In this context, if one side has introduced only a part of a document, the other side can bring in the remainder of that document to ensure that the fact-finder has a complete understanding of the evidence. The overall purpose is to promote fairness and accuracy in the trial by allowing the necessary context surrounding pieces of evidence that could otherwise lead to misunderstanding if presented in isolation.
