How does a petit jury decide the facts in a trial?

A petit jury is a group of citizens selected to deliberate on questions of fact during a trial, while the judge retains authority over questions of law. The jury’s decision-making process is supervised by the judge, who determines what evidence the jury may consider and instructs them on the applicable legal standards.21

To decide the facts, the jury typically renders a general verdict—a simple "yes" or "no" regarding guilt or liability—without providing specific reasons for its conclusion. In some instances, courts may use "special verdicts" or "special interrogatories," which require jurors to resolve a series of specific factual issues that contribute to the final verdict.2

While the jury is tasked with finding the facts, its performance is often influenced by its own sense of justice, which can lead to deviations from a judge's expected outcome. The judge maintains oversight and may set aside a verdict if it is found to be manifestly against the weight of the evidence, though a criminal acquittal is generally final under Anglo-American law.321
