If someone comes to his house and hits someone, the owner will hurt him. If it constitutes a minor injury or more, it is a crime of intentional injury. The actor shall compensate the victim for the expenses of hospitalization. If the injury is minor, it will generally be detained and fined. If the injury identification conclusion is more than minor injuries, the actor needs to bear criminal responsibility. The crime of intentional injury causing minor injuries shall be sentenced to fixed-term imprisonment of not more than three years, criminal detention or public surveillance.
Excessive defense refers to a criminal act that obviously exceeds the necessary limit and causes great damage and should bear criminal responsibility. Excessive defense is a legitimate defense behavior that exceeds the defense scale stipulated by law and should bear criminal responsibility. Whoever intentionally harms another person's body shall be sentenced to fixed-term imprisonment of not more than three years, criminal detention or public surveillance. Excessive defense caused minor injuries to the other side, but the circumstances were minor. According to medical expenses, lost time, nursing expenses, disability compensation determined according to disability level, and mental damages, compensation shall be determined through consultation according to the fault ratio of both parties. In the case of positive compensation or the understanding of the victim, it may not be treated as a crime, that is, criminal responsibility shall not be investigated. If you can't actively compensate or get the victim's understanding, but because the subjective malignancy of excessive defense is not great, and you surrender yourself voluntarily and have a good attitude of repentance, you can be sentenced to criminal detention or control, or suspended.
