What is the level of proof for a grand jury or preliminary hearing?

• A. Beyond a reasonable doubt
• B. Clear and convincing evidence
• C. Preponderance of the evidence
• D. Probable cause

Answer: (D)

Probable cause is the level of proof used at charging stages like a grand jury or a preliminary hearing. In these settings, the question is whether there is a reasonable basis to believe the person committed the crime, not whether guilt has been proven. A grand jury reviews evidence presented by the prosecutor to decide if there is enough probable cause to indict; they’re not deciding guilt or innocence. A preliminary hearing serves a similar gatekeeping role in which a judge determines whether there is probable cause to bind the defendant over for trial. This standard is intentionally lower than what’s required for a conviction, balancing the need to prevent unfounded charges with the interest of avoiding unnecessary delays in bringing someone to trial. The other options—beyond a reasonable doubt (for trial convictions), clear and convincing (a higher, specific civil/criminal standard in certain contexts), and preponderance of the evidence (civil standard)—do not apply at these charging stages.
