What is selected to examine the truth of an accusation prior to a trial.?

Before a trial, a preliminary hearing or a grand jury proceeding is typically used to examine the truth of an accusation. In a preliminary hearing, a judge assesses whether there is enough evidence to proceed to trial. In grand jury proceedings, jurors review evidence presented by the prosecution to determine if there is sufficient cause to issue an indictment. Both processes serve to ensure that only valid cases move forward in the judicial system.
