To be valid and enforceable, criminal laws must specifically describe the conduct that is prohibited, and declare its commission to be a crime.

• A. True
• B. False
• C. It is not necessary to describe prohibited conduct
• D. They may be implied by enforcement practice

Answer: (A)

In criminal law, statutes must define the prohibited conduct and declare that its commission is a crime. This guarantees due process by giving people clear notice of what behavior is illegal and by allowing the government to prove the offense through the statute’s defined elements. The description typically includes the specific act and, where required, the mental state and result, so there’s a concrete standard for both enforcement and adjudication. Laws that are vague or rely on enforcement practice to create crimes fail the notice-and-prohibition test and can be struck down; a crime cannot be created by practice alone. This principle helps ensure predictable, fair enforcement, which is especially important for emergency services personnel who must understand what actions are legally permissible or prohibited.
