“Criminal justice” is a field of study in the realm of contemporary criminal sciences, which derives from legality and law enforcement. In terms of its subject and content, criminal justice and criminal policy can be defined as the same concept with two terms from two different discourse-conceptual origins, which are also referred to as “criminal justice policy” in some references. This article, by adhering to the same concept of criminal justice and criminal policy and assuming criminal policy in the heart of criminal justice, examines the models coming from this concept, from an approach called “Alavi’s criminal justice”. In the light of this concept of criminal justice, the problematic point of the article is to seek a model of Alavi’s criminal policy in the Islamic Republic of Iran. The meaning of Alavi’s criminal policy model is the redefining of criminal justice policy in the light of Imam Ali's thoughts or the Alavi’s criminal justice policy, which is defined and measured by the criteria of Islam. Alavi’s criminal justice and its policy-making, in the light of the six-fold models of criminal justice in contemporary criminal sciences, includes a chain of models that can be divided from the crime control model, due process model, rehabilitation model, to the equal justice model, non-intervention model and restorative justice model.
