After the four decades, the Islamic Republic of Iran has used political and economic models that has left special influences in the geographical space of Iran according to the political thought embedded in it. However, the common point of all spatial patterns in the Islamic Republic of Iran has been activism within a completely centralized pattern. The increasing concentration of affairs in centralized political-spatial units causes shortcomings and inadequacies that disrupt the spatial distribution of justice and development at the same time; Because the political-spatial units that make up countries have a different and heterogeneous set of natural-human elements and factors. Hence, the issue of the form and process of spatial distribution of power in such units has always been a fundamental concern of geographers. Iran, as a political-spatial unit, has also struggled with the functional patterns of power distribution. In this regard, the present study with a descriptive-analytical method has investigated the feasibility of using the semi-centralized model of local government for the optimal distribution of power within the judiciary and security in Iran. The results show that by doubling the spatial distribution of power in Iran into two parts of local affairs and governance, a logical framework for the application of each of these two parts emerges. In judicial affairs, organizations such as the Registry of Deeds and Property, the Organization of Prisons and Security-Training Measures, the Center for Dispute Resolution Councils, and the Forensic Medicine Organization have an increasing capacity to delegate to local governments due to their service-welfare nature. In the field of security, the categories and organizations in the police force, such as the Passport Office, the Public Service Organization, categories of the Preventive Police and the Traffic Police, due to the preventive nature and services can be Delegate local affairs representatives.
