Islamic Azad University, public or private institution?

One of institutions that there is doubt about its nature is Islamic Azad University. In Article 5 of the new constitution of Islamic Azad University determined at first as a non-governmental public institution، and in later amended، a non-private non-governmental institution. The term «non-private non-governmental organization» is not recognized within the institution in law and it appears that Council''s goal from using non-governmental near non-private is public. But is the Islamic Azad University a non-governmental public institution? There are some of public law personality''s features such as doing public service and using some of the power rating in the university but in the other criteria، it has the privacy law persons features. Despite in the new Constitution، university is called as a non-governmental public institution but according to civil service management act، identification or creation and abolishing a non- governmental public institutions do only by monopoly of the Islamic Consultative Assembly. Therefore if we want to know the university as a non-governmental public institution we need to clarify the identification as a non-governmental public institution by the legislator.
