This paper seeks to compare the model of publicsector in the economic model of I.R.I. Constitution and economies of WelfareStates. Thecomparison isbased on ideological principles and economic rules governing the public sector. We find that state role in both models properlyfollows the conventional economic literature on public sector, which focuses on naturalrole of state in the economy. Considering ideological literature and institutionalcapacity of state in both models, however, we find that I.R.I. constitution has moreinstitutional preferences compared with welfare state model. Primary source of this difference is inefficiencyof welfare state model, especially its inefficient system of economic norms (ideology) in practice which is extends far away from justice goals and wideninggaps in the economy. Normativeframework of public sector in economic model ofI.R.I. constitutionhas the capacity of securing economy from these inefficiencies. Regarding this, wepropose the state using the current fundamental capacity in the economic model of I.R.I. constitution, seeks grounding public participation towards constituted goals of the economy. As a practical approach, the state focusing on improvement and development ofeconomic culture, may achieve an efficient economic system through implementing economicjustice and revising the property movement pattern.

 The Social Rule of Law is a type of the rule of law, originating from the tradition of social democracy. The research aims to examine the evolution of the rule of law into a socially-oriented model, focusing on its principles, goals, and structure. Key research questions address the essence, goals, and functions of the Social Rule of Law. The research uses a descriptive method and the data collection tool is library. Hermann Heller, as the founder of the concept, argues that democratic-based approach allows for the harmonization of the rule of law with social orientation, showing similarities between the Social Rule of Law and the Liberal Rule of Law. The findings of the research show that the Social Rule of Law reconfigures the private sphere in order to safeguard the social rights of citizens, eliminating social oppression within civil society. Its primary functions include monitoring private relationships between citizens and ensuring social security through the involvement and control of the government. The critical requirements for this system include expanding the executive, strengthening social legislation, ensuring substantive equality, and increasing the powers of the judiciary and parliament to deal with social rights.
