Illegal acts are also called "invalid acts". An illegal act. Acts that violate the law. Different from the objective illegal behavior, the actor is subjectively at fault when carrying out the behavior, thus infringing on the social relations protected by law. Subjective fault refers to the subjective state of intention or negligence. According to the nature of illegality, illegal acts can be divided into criminal violations, civil violations, economic violations and administrative violations. According to the degree of harm to society, illegal acts can be divided into general illegal acts and serious illegal acts (crimes).

The concept of illegality has broad and narrow meanings. In a broad sense, illegality refers to all acts that violate the existing laws, including general illegal acts and criminal acts. In a narrow sense, illegality refers to a serious violation of the law but does not constitute a crime. What we are discussing here is illegality in a broad sense.

The connection between illegality and crime is that crime must be illegal, and illegality is not necessarily a crime. The difference is that the degree of social harm of crime is more serious than that of illegal behavior. Most criminal acts bear criminal responsibility, while illegal acts bear administrative or civil responsibility.

There is a difference between illegal behavior and other behaviors. First of all, illegal behavior is different from immoral behavior. Many illegal acts are both criminal and immoral. However, not all illegal acts are immoral. Similarly, some immoral acts do not constitute illegal acts. Secondly, illegal acts are different from legally invalid acts. Of course, an illegal act can't produce the effective result that the perpetrator hoped when he committed the illegal act. However, it cannot be considered that all legally invalid acts are illegal. Although some legally invalid acts have no legal effect, they do not constitute illegality.
