Trier of fact
In law, a trier of fact or finder of fact is a person or group who determines which facts are available in a legal proceeding (usually a trial) and how relevant they are to deciding its outcome. To determine a fact is to decide, from the evidence presented, whether something existed or some event occurred.

The factfinder differs by the type of proceeding. In a jury trial, it is the jury; in a non-jury trial, the judge is both the factfinder and the trier of law. In administrative proceedings, the factfinder may be a hearing officer or a hearing body.
