What is the purpose of a preliminary hearing?

The purpose of a preliminary hearing is to determine if there is enough evidence to proceed to trial. During this stage, the judge evaluates the evidence presented by the prosecution to assess whether there is probable cause to believe that a crime was committed and that the defendant is likely responsible. This hearing acts as a safeguard to protect individuals from being subjected to unnecessary trials when the evidence is insufficient.

The preliminary hearing serves as an important check on the legal process, allowing the defense to challenge the prosecution's evidence and arguments. If the judge finds that the evidence meets the required standard of probable cause, the case moves forward to trial; if not, the charges may be dismissed.

The other choices relate to different legal processes. Finalizing charges against a defendant typically occurs through formal arraignment or indictment rather than a preliminary hearing. Assessing the defendant's mental competency is a separate procedure that evaluates whether a defendant can understand the charges against them or participate in their defense. Witness testimonies may be presented during various stages of a trial or investigation but are not the primary focus of a preliminary hearing, which primarily concerns evidence evaluation.
