When the jury consists of only one person who is the juror?

When the jury consists of only one person, that individual is referred to as a "juror." In such cases, the single juror is responsible for evaluating the evidence presented in a trial and rendering a verdict. This arrangement is uncommon in most legal systems, which typically require a group of jurors to deliberate collectively. The use of a single juror may occur in specific circumstances, such as in certain types of civil cases or informal dispute resolutions.
