What is the primary function of a jury in a court case?

The primary function of a jury in a court case is to listen to evidence and determine the facts of the case. This role is fundamental to the judicial process, as jurors assess the credibility of witnesses, weigh the presented evidence, and apply the law as instructed by the judge to arrive at a verdict. Their findings of fact are critical because they reflect the community's judgment on the evidence and circumstances surrounding the case. This function supports the principle of a fair trial, ensuring that a defendant is judged by a group representing peers, rather than solely by a judge or governmental authority.

In contrast, enforcing laws and ensuring justice is primarily the role of law enforcement and the judicial system as a whole, rather than the jury itself. The jury does not represent the interests of the defendant directly; instead, it acts as an impartial body assessing the evidence objectively. Additionally, the prosecution of a case is the responsibility of the prosecutor or district attorney, who represents the state, while the jury merely evaluates the evidence presented to them by both sides.
