ultimate fact

ultimate fact n. in a trial, a conclusion of fact which is logically deduced from evidence ("evidentiary facts"). Example: the evidentiary facts were that driver Larry Leadfoot a) exceeded the speed limit, b) drove over the double-line, c) skidded and lost control of his car; the ultimate fact was, therefore, Leadfoot was negligent. It is essential to introduce the evidentiary facts during the trial in order to prove the ultimate fact. A mere statement by a witness that "Leadfoot was negligent" is not sufficient, since it is an opinion of the witness and is not evidence. (See: evidence)
