Doctrine of Vagueness

/ˈdɒktrɪn əv vəˈɡjuːnəs/

Definitions

  1. (n.) A constitutional law principle holding that laws must be clear and specific enough to provide adequate notice of prohibited conduct, or else risk being invalidated for vagueness.
    The court struck down the statute under the doctrine of vagueness because it failed to define key terms clearly.

Commentary

Ensure statutes specify conduct and penalties precisely to withstand vagueness challenges and protect fair notice and consistent enforcement.
