The prohibition against adding witnesses does not apply to which types of witnesses or documents?

The prohibition against adding witnesses primarily refers to the constraints placed on parties from introducing new evidence or witnesses after a certain point in legal proceedings. However, there are exceptions to this rule, particularly concerning the introduction of witnesses for impeachment and rebuttal purposes.

When a party presents their case, the opposing party may have the right to introduce additional witnesses or evidence specifically to counter or challenge the credibility of prior testimony or to refine or clarify points already introduced in the case. This is essential for maintaining fairness in the trial process, allowing for effective cross-examination and ensuring that both sides can adequately respond to the points brought up in testimony.

The other options, while they each pertain to specific categories of witnesses or evidence, do not represent the same allowable exceptions to the prohibition against adding witnesses. For example, while expert witnesses can play a critical role in trials, they typically must be disclosed prior to the trial to ensure that both sides can prepare adequately. Similarly, character witnesses or historical witnesses would generally need to be identified before a trial to adhere to procedural fairness. Therefore, the allowance of new evidence for impeachment or rebuttal is recognized as a necessary and legitimate aspect of legal proceedings.
