Here’s a question that arose during a recent class: Suppose that a party in a criminal case seeks to introduce forensic evidence from a discipline of questionable validity, such as bite mark analysis.

Expert Discovery
For a variety of reasons, I’ve spent some time recently looking at expert discovery in criminal cases. I thought I’d put together a short summary of the law.
