FEDERAL RULES OF EVIDENCE

ARTICLE VII. OPINIONS AND EXPERT TESTIMONY

Rule 704. Opinion on Ultimate Issue

(a) Except as provided in subdivision (b), testimony in the form of an opinion or
inference otherwise admissible is not objectionable because it embraces an ultimate
issue to be decided by the trier of fact.

(b) No expert witness testifying with respect to the mental state or condition of a
defendant in a criminal case may state an opinion or inference as to whether the
defendant did or did not have the mental state or condition constituting an element of
the crime charged or of a defense thereto. Such ultimate issues are matters for the
trier of fact alone.
