Incident, act, event, or circumstance. A fact is something that has already been done or an action in process. It is an event that has definitely and actually taken place, and is distinguishable from a suspicion, innuendo, or supposition. A fact is a truth as opposed to fiction or mistake.
A QUESTION OF FACT in litigation is concerned with what actually took place. During a trial, questions of fact are generally left for the jury to determine after each opposing side has presented its case. By contrast, a QUESTION OF LAW is ordinarily decided by a judge, who must deal with applicable legal rules and principles that affect what transpired.
