Privatization of Criminal Law in Consideration of Law on reducing the punishment of imprisonment

Law on reducing the punishment of Taziri imprisonment was enacted in May 12, 2020. This law has made important amendments to the body of Iranian criminal law. It could be addressed in two aspects: theoretical and practical. The second one- legislator's mean to reducing the criminal population- should be considered in a result-based process after a reasonable period of time from its implementation. In theoretical view however these reforms can be the basis of more fundamental researches. The study of the recent enacted law shows an important change of criminal concepts that we call it Privatization of Criminal Law. Examples of this flow can be enumerated as follows: first, increasing the number of forgivable crimes. Second, The obvious effect of complainant's action on the nature of crimes. Third The possible effect of the complainant's action on the disappearing of the legal element of the crime. Fifth, complainant's role in determining the jurisdiction and limits of the authority of the reviewing authority. In this study, using the analytical method, the change in the attitude of the criminal legislator has been investigated. The findings of the study prove that the boundaries of criminal law are eroded and the concept of complainant is closer to the plaintiff and consequently the complaint to the petition, which occurred as a result of changing the legislator's position to the victim's place in criminal law.
