What is the term for the ordinary jury that is distinct from a grand jury?

The term for the ordinary jury that is distinct from a grand jury is "Petit Jury." A Petit Jury is the group of citizens tasked with evaluating evidence and making a determination in a trial, typically in criminal or civil cases. This jury is responsible for reaching a verdict based on the facts presented during the trial, which includes evaluating witness testimonies, evidence presented by both the prosecution and defense, and adhering to legal standards for deliberation.

In contrast, a grand jury is used primarily during the pre-trial phase to determine whether there is sufficient evidence to charge a person with a crime. It does not determine guilt or innocence, but rather whether there is enough evidence to proceed with a trial. Other options, such as a "Pleas Jury" and "Trial Jury," do not represent established legal terminology for the ordinary jury, while a "Federal Jury" refers specifically to juries that operate in the federal court system, rather than distinguishing the ordinary jury from a grand jury. Thus, the Petit Jury is the correct term to describe the ordinary jury involved in trials.
