Our current manuscript includes shedding light on the most important means that define the penal code and its goal, with a mention of what is related to it at the judicial level, depending on the most important sources approved in this field according to data and documents published globally. What is meant by the Crimes and Penalties Law is to give the legislator alone the power to have the ability to specify the acts punishable by law, which are called crimes, and to determine the penalties that apply to the perpetrators, which are called penalties. Any situation that occurs in society in which the perpetrators of the crime cannot be punished unless there is a legal basis or text on which the judge relies, during which the law is applied by all its means, and no one can reject this procedure as it is issued from an internationally agreed legal method.
