SUMMARY
With approval of implementation law of general policies of Article 44 of constitution in 2008 and the division of economic activities in three groups, the government was obliged to transfer activities, institutions and companies to non-governmental sector other than those that will remain at government disposal (group III), such as parent telecommunication network, postal exchanges core network, core networks of power transmission and dams and large-scale irrigation networks and also maximum 20% of economic activities mentioned in Article 44 of the constitution (group II). As a result, the government has to give up a large part of public services such as production and distribution of water and electricity and telecommunications. Since beforehand the government either by direct ownership or through preferred stock administered and managed these services and applied authority by this way, the government will lose the means to exercise its sovereignty with transfer of ownership and implementing public services privatization; so, in order to compensate this gap of authority, a new legal system was considered to impose ruling on public services private institutions that in this article, its bases, frameworks and options are addressed.
