Originally designed as a brief hearing to weed out groundless felony complaints, the preliminary examination has become, perhaps, the most important stage of the criminal process in California. Set in court soon after the filing of the criminal complaint, the examination is the time and place for the superior court judge, called a magistrate during these proceedings, to determine the sufficiency of the evidence against the accused and to consider motions to suppress that evidence. When the prosecution satisfies its burden of proof, the defendant is bound over for trial. When it fails to do so, the magistrate dismisses the complaint and discharges the defendant. Each of these decisions is reviewable in the superior court.
