What is the function of a petit jury?

A petit jury, also known as a trial jury, primarily serves the function of determining the facts in a civil or criminal action. This jury listens to the evidence presented during a trial, evaluates the credibility of witnesses, and assesses the arguments made by both parties to arrive at a verdict. The petit jury is composed of a group of citizens who represent a cross-section of the community, ensuring that the decision reflects a collective judgment based on the facts and evidence.

The role of this jury is crucial in the judicial process, as they are tasked with deciding the outcome of cases based on the evidence presented and the applicable law as explained by the judge. This differs significantly from the responsibilities of an appellate jury or legal advisor, as their primary focus is on factual determinations rather than legal interpretations or mediation functions.
