What authority does a judge have concerning witnesses in a trial?

A judge holds the authority to interrogate witnesses in order to uncover necessary facts vital to the case. This role is crucial for ensuring that the court has a clear understanding of the evidence presented. The judge may ask questions to clarify inconsistencies, elicit additional information, or ensure that the testimony aligns with the legal requirements of the trial process. This direct engagement with witnesses enhances the ability of the court to make informed decisions based on the facts, which is fundamental to the trial's integrity.

The other choices reflect responsibilities and powers of a judge but do not accurately describe the primary role regarding witness interrogation. While determining credibility and evidence admissibility are essential tasks within the trial process, and summarizing proceedings may occur in certain contexts, the direct questioning of witnesses to uncover necessary facts is a specific power that emphasizes the judge's critical role in managing the trial effectively.
