What is the role of a jury in state trial courts?

In state trial courts, a jury serves as a group of impartial citizens tasked with evaluating evidence presented during a trial and rendering a verdict based on that evidence. They determine the facts of the case, assess witness credibility, and apply the law as instructed by the judge. The jury's decision can lead to a conviction or acquittal in criminal cases, or a judgment in civil cases. Their role is fundamental to ensuring a fair trial and upholding the rights of the accused or the parties involved.
