What type of crime involves actions that are criminalized by statute?

The term "malum prohibitum" refers to actions that are criminalized by statute, indicating that they are not inherently wrong but are considered criminal due to specific laws. This concept is essential in understanding that certain behaviors are deemed illegal because legislatures have enacted laws prohibiting them, rather than because they violate moral or ethical standards.

For example, driving over the speed limit is a malum prohibitum offense; it is not considered morally wrong in itself but is regulated by law for public safety. The classification highlights the role of regulatory frameworks in defining criminal activity.

In contrast, "malum in se" pertains to acts that are inherently wrong or evil, such as murder or rape, which are universally condemned across cultures. Felonies and misdemeanors are types of crimes based on the severity of the offense, but they do not specifically address the relationship between statutes and the nature of the act like the term "malum prohibitum" does.
