The criterion of

The acts of the State in administrative law، according the criterion of the method، are divided into act of authority and act of management. This division is used in the different areas of administrative law such as the determination of the competent judge، the rules of civil liability of the state، etc… In the system of administrative law of Iran، the criterion of the act of authority is used in the above fields. But we have shown in this writing، that the act of authority as the criterion of legal competence and the rules of civil liability of the State is canceled، and also in the areas of criminal liability and administrative organization and civil service، despite the legal credit، this criterion is without any efficiency because of vagueness in its concept، and its effect is limited in the scope of making politics.
