What is the role of a jury in a trial?

The role of a jury in a trial is primarily to determine the facts based on the evidence presented and to render a verdict based on those findings. This encompasses evaluating witness testimonies, examining physical evidence, and considering the arguments from both the prosecution and defense. The jury's function is crucial in upholding the legal principle of a fair trial, where a group of impartial peers assesses the case rather than a single individual, such as a judge, making the decision alone.

Unlike executing punishment or advising on sentences, which are not part of the jury's responsibilities, the jury focuses solely on factual determinations and reaching a conclusion about the guilt or innocence of a defendant. This distinct role underscores the separation of powers in a trial, where the jury handles fact-finding while the judge deals with legal interpretations and procedural rules.
