Burden of proof in criminal trials.

• A. Proof beyond reasonable doubt is required for conviction.
• B. Proof beyond all doubt is required.
• C. Proof on the balance of probabilities is required.
• D. Proof by a simple majority is required.

Answer: (A)

The main idea here is the standard of proof required to convict someone in a criminal trial. In criminal cases the prosecutor carries the burden of proving the defendant’s guilt, and the defendant is presumed innocent. The level of proof needed is beyond reasonable doubt. This is intentionally high to protect liberty, meaning the evidence must leave the fact-finder firmly convinced of guilt. It doesn’t require absolute certainty, but it must rule out reasonable doubts that a reasonable person might have after considering the evidence. If there is a reasonable doubt, the verdict should be not guilty.

Why the other statements don’t fit: there isn’t a standard of proof called “beyond all doubt,” because no system requires absolute certainty. “Beyond a doubt” would be impractical and unnecessary; the correct standard recognizes that some doubt may remain. The balance of probabilities standard is used in civil cases, not criminal, where the outcome is not imposing possible loss of liberty. A simple majority relates to voting thresholds, not the strength of the proof; the decision in a criminal case must meet the level of beyond reasonable doubt regardless of majority support.
