Direct personal interest is a prerequisite for the establishment of an abolition case. But this interest may fade when one looks into the case and this happens also before the final judgment. To address this situation, the Jordanian and Egyptian Administrative Judiciary - contrary to what was stable in the French State Council -, has decided to consider the dispute as ended. Therefore, this research aims at demonstrating the importance of continuing to see the abolition case despite the demise of the plaintiff interest, and the protection of the principle of legality and the public interest. This present research is divided into four chapters; the preliminary chapter deals with the essence of annulment action; chapter one is about the nature of interest as a condition for accepting the annulment; chapter two deals with the time of the availability of interest in the annulment and chapter three is about the nature of demurrer in the absence of interest. Finally, the research is ended with conclusions and recommendations that we reached through a comparative analytical Provenience approach.
