A reason for invalidating a statute where a reasonable person could not determine a statute's meaning?

• A. Void for vagueness
• B. Self-defense
• C. Entrapment
• D. Duress

Answer: (A)

Void-for-vagueness explains why a statute can be invalidated when a reasonable person cannot determine its meaning. This doctrine rests on due process: laws must give people fair notice of what is illegal and must be clear enough to apply consistently. If a statute is so unclear that an ordinary person cannot tell what conduct is prohibited or what the penalties are, courts strike it down to prevent arbitrary enforcement and chilling effects. An example would be a rule banning “unreasonable noise” without defining what counts as unreasonable or specifying quiet hours. The other options describe defenses to criminal liability (such as justifications or excuses) and do not address whether the law itself is sufficiently clear.
