Which of the following is NOT a function of a Grand Jury?

A Grand Jury serves several important functions in the legal system, primarily relating to the initiation of criminal proceedings. One of its primary roles is to consider evidence presented and determine whether there is sufficient cause to issue an indictment, which is the process of formally charging someone with a crime. This reflects the Grand Jury's function to assess the validity of allegations made against a potential defendant.

The Grand Jury does not determine innocence or guilt; that responsibility falls to a trial jury, which hears evidence to make a determination of guilt or innocence in a criminal trial. While a Grand Jury does review evidence and may assess the credibility of witnesses in that context, its sole purpose is to decide if there is enough evidence to support an indictment. Therefore, determining the innocence of the accused is not a function of a Grand Jury, making it the correct answer in this context.
