There are disputes about the normativity of administrative conventions in academic circles. Before entering the judicial process administrative conventions are rules constructed by administrative organs based on self-identification. The external aspect of administrative conventions is the long-term unified behavior of officials and the internal aspect is the approval of officials. Administrative conventions usually do not directly regulate the behaviors of administrative officials but the officials could be bound by the administrative act based on the administrative conventions. The authority of the administrative organ will catalyze the normativity of the administrative conventions. When the administrative organ goes against the administrative conventions the administrative officials can claim the reliance interest protection. For judicial review the existence of administrative conventions is first a matter of fact they can be used as juridical reasons rather than judgement rules. In this sense administrative conventions are not the sources of law for judges.
