Аn administrative claim in general and the right to satisfy an administrative claim in particular are basic and fundamental institutions of administrative justice, performing the function of a human rights instrument, ensuring judicial protection of the rights, freedoms and legitimate interests of citizens. The concept, legal nature and structure of the right to satisfy an administrative claim acquire special importance. After all, the motivation of the right to judicial protection and the right to appeal to an administrative court is the satisfaction of the plaintiff's administrative claim. In order to exercise the right to satisfy an administrative claim, it is not enough just to present an administrative claim. The claim must be substantiated by factual data in accordance with the procedure prescribed by law. Thus, the grounds necessary for the realization of the right to satisfy an administrative claim are: 1) the existence of the right to present an administrative claim; 2) compliance with the term of appeal to the administrative court or the seriousness of the reasons for its omission; 3) provenance of the grounds of the administrative claim; 4) legal validity of the administrative claim. The right to the satisfaction of an administrative claim is understood as the right of the plaintiff to demand from the administrative court a positive judgment for him on the merits of the claims, provided that the grounds of the administrative claim are well-founded in compliance with the norms of substantive law and the term of appeal to the court or the seriousness of the reasons for its omission.
