Under the Effect of code, when does conduct constitute an offense?

• A. It is an offense by default
• B. Conduct is offense only if defined by statute, municipal ordinance, or order of a commissioners court
• C. Conduct is always offense
• D. Conduct does not constitute an offense unless defined by statute, municipal ordinance, or order of a commissioners court

Answer: (D)

In criminal law, conduct becomes an offense only when a law defines it as such. A person can be charged only if the action is prohibited by a statute, a municipal ordinance, or an order of the commissioners court that specifies it as illegal and prescribes a penalty. Without that legal definition, there is no offense being committed, even if the behavior seems improper. This is why it’s not an offense by default or in every situation—it requires a defined prohibition. Local authorities can create offenses through ordinances or official orders, and that definition is what makes conduct prosecutable.
