The trier of fact, also called the finder of fact, is the person or persons responsible for deciding the factual issues Iin a criminal trial, which is also called a finding of fact. In a jury trial, the trier of fact is the jury. If there is no jury, the trier of fact is the judge.
"Trier of fact" is now considered an older term m and the term "finder of fact" has come into use more recently.
In many types of hearings, the trier of fact may be an administrative law judge, a board, commission, or a referee. Once the trier of fact determines what is assumed to be the truth of a matter, legal rules are applied to those facts. A judge instructs a jury about the legal rules applying to the case. The instructions include what the findings may be. For example, the jury may find for the plantiff or for the defendant.
