Under the void-for-vagueness doctrine, when is a law declared invalid?

• A. It applies only to criminal statutes.
• B. If a reasonable person in the defendant's situation cannot understand what was prohibited by the ordinary meaning of the words, the law does not give fair notice and is declared to be unconstitutionally vague.
• C. The doctrine requires the court to rewrite the law to fit constitutional standards.
• D. It allows vague statutes if enforcement is limited to exceptional cases.

Answer: (B)

Fair notice under due process is the central idea here. A law must clearly tell an ordinary person what behavior is prohibited. If the ordinary meaning of the words leaves a reasonable person in the defendant’s situation unable to understand what is forbidden, there is no fair notice, and the statute is unconstitutionally vague. This protects against arbitrary enforcement and ensures people aren’t punished for conduct they couldn’t reasonably know was illegal. For example, a rule banning “annoying behavior” is vague because “annoying” can vary from person to person; a statute with more precise, concrete prohibitions gives a person a workable guide to what is illegal. The other statements don’t fit the doctrine: the vagueness challenge isn’t limited to criminal statutes, it isn’t about the court rewriting the law to fit constitutional standards, and vague statutes aren’t permissible merely because enforcement would be limited to exceptional cases.
