What is the function of a grand jury?

The function of a grand jury is to hear criminal accusations and decide on indictments. A grand jury is composed of a group of citizens who are called to review evidence presented by a prosecutor regarding potential criminal activity. Their role is to determine whether there is enough evidence to formally charge an individual with a crime, thus initiating criminal proceedings. This process is crucial as it serves to protect individuals from unwarranted prosecutions, ensuring that there is probable cause before a case goes to trial. Unlike a trial jury, which determines guilt or innocence in a civil or criminal case, the grand jury operates in the pre-trial stage and does not decide on the verdict of a case.

This role is distinct from the functions of determining sentencing or overseeing appeals, which are associated with trial juries and appellate courts, respectively. Therefore, the correct answer highlights the grand jury's specific duty in the legal system to evaluate accusations and support the integrity of the judicial process.
