What best describes omission in culpable mental states?

• A. A deliberate action that causes harm
• B. Failure to do what the law requires
• C. A mistake of law
• D. An accidental result

Answer: (B)

Omission in culpable mental states means criminal liability can arise from not doing something the law requires. It requires a legal duty to act—such as a statutory duty, a special relationship, a contractual obligation, or the creation of a dangerous situation—and then a person’s failure to perform that duty. The moral element can involve knowingly or recklessly failing to act or being grossly negligent in the face of a duty. This is why “failure to do what the law requires” is the best description. Descriptions of deliberate actions causing harm describe a commission, a mistake of law isn’t about failing to act, and an accidental result isn’t tied to a failure to act under a duty.
