Rule 704. Opinion on Ultimate Issue.

 

(a)      In General — Not Automatically Objectionable. An opinion is not objectionable just because it embraces an ultimate issue.

(b)      Exception. In a criminal case, an expert witness must not state an opinion about whether the defendant did or did not have a mental state or condition that constitutes an element of the crime charged or of a defense. Those matters are for the trier of fact alone.
