What is one primary function of a grand jury?

One primary function of a grand jury is to determine if there is enough evidence to proceed to trial. This process involves reviewing evidence presented by the prosecution to assess whether there is probable cause to believe that a crime has been committed and that the accused individual should be formally charged. The grand jury acts as a check on prosecutorial power, ensuring that individuals are not subjected to prosecution without adequate grounds.

In this role, the grand jury serves the legal system by protecting citizens from unwarranted criminal charges, thereby reinforcing the principle of due process. This function is particularly crucial as it emphasizes the role of evidence in the legal process before moving forward with a trial, ensuring that only cases with sufficient basis are advanced in the judicial system.
