What does Rule 31.35 allow for expert witnesses?

Rule 31.35 allows for the presentation of expert evidence in a manner that facilitates a more dynamic and interactive exchange between experts. This rule enables simultaneous presentation, meaning that multiple expert witnesses can provide their evidence at the same time, allowing for direct questioning and discussion among them. This approach can enhance the clarity and efficiency of the evidence being presented, as it creates an opportunity for experts to engage with one another, address differing viewpoints, and clarify complex issues in real-time. This format is particularly beneficial in complex cases where expert testimony can be intricate and interrelated.

The other options do not accurately reflect the provisions or intentions of Rule 31.35. For instance, having only one expert testify at a time would limit the opportunity for interaction and dialogue, which is central to the rule's intent. Similarly, not allowing communication between experts would hinder the collaborative aspect of presenting expert testimony, which Rule 31.35 seeks to promote. Lastly, while written reports from experts might still be required, the core of Rule 31.35 is focused on the presentation and process of giving expert testimony in court.
