The article is devoted to the study of various approaches to understanding the phenomenon of a miscarriage of justice in administrative proceedings. The author establishes that a miscarriage of justice in administrative proceedings can be referred to in several senses. Firstly, a miscarriage of justice in administrative proceedings can be understood in a narrow sense, depending on the aspect specifically chosen (epistemological, praxeological and teleological) or their combination. The epistemological aspect of understanding a miscarriage of justice in administrative proceedings relates to the processes of mental and cognitive activity of a judge. Within this aspect, a miscarriage of justice is considered as a result of a defect in the subject matter of a judge’s cognitive actions, which may be manifested in incorrect processing or interpretation of information. The praxeological aspect of understanding a miscarriage of justice in administrative proceedings focuses on the compliance of the judge’s actions with the requirements and procedural rules set forth in the law. In this context, a miscarriage of justice is manifested as an unlawful act (action or inaction) of a judge, which consists in the judge’s incorrect application of substantive law or violation of procedural law. The teleological aspect of understanding a miscarriage of justice relates to the purposes of administrative proceedings. Under this approach, a miscarriage of justice is defined as a result that does not meet the goals of administrative proceedings. The interconnection and interdependence of the epistemological, praxeological and teleological aspects forms a comprehensive understanding, a holistic perception of this phenomenon in administrative proceedings. This integration of different perspectives makes it possible to characterize a miscarriage of justice by providing a deep and multilevel understanding of its nature. In a broad sense, a miscarriage of justice in administrative proceedings can be understood as a judge’s procedural activity related to the misperception, analysis or reproduction of legal norms, which is reflected in the adoption of a court decision that is unable to achieve the purpose of administrative proceedings.
