Hypothetical Question

Hypothetical Question

A mixture of assumed or established facts and circumstances, developed in the form of a coherent and specific situation, which is presented to an expert witness at a trial to elicit his or her opinion.

When a hypothetical question is posed, it includes all the facts in evidence needed to form an opinion and, based on the assumption that the facts are true, the witness is asked whether he or she can arrive at an opinion, and if so, to state it.
