Common questions
Frequently Asked
4
Does the reasonable doubt standard apply in juvenile delinquency proceedings?+
Yes. The Due Process Clause requires proof beyond a reasonable doubt of every fact necessary to constitute the charged offense in juvenile adjudications as well as adult criminal trials.
Supporting sources
What happens if the prosecution fails to meet the reasonable doubt standard on any element?+
The defendant must be acquitted. The presumption of innocence remains in force and no conviction may be entered when reasonable doubt exists on any element of the offense.
Supporting sources
Is the reasonable doubt standard used to determine whether a person is a slayer in probate proceedings?+
No. The slayer determination in a civil proceeding uses the preponderance of the evidence standard, although a final criminal conviction for intentional killing conclusively establishes slayer status.
Supporting sources
Does the reasonable doubt standard govern the admissibility of a confession?+
No. The prosecution need only prove the voluntariness of a confession by a preponderance of the evidence at a suppression hearing. The reasonable doubt standard applies only to the jury's determination of guilt.
