The article is dedicated to the study of a lawsuit as a means of protecting violated rights in administrative proceedings. Considering the amendments to the legislation, the issue of the significance of a lawsuit in the context of protecting violated rights in administrative proceedings has become increasingly relevant. Under the previous version of the Code of Administrative Procedure of Ukraine, a lawsuit was the foundational document, without which the protection of violated rights in administrative proceedings would be nearly impossible. It has been demonstrated that the current version of the Code of Administrative Procedure of Ukraine has significantly detailed the right to apply to the court, particularly regarding the potential application of remedies by the court. A lawsuit, serving as the basis for initiating proceedings, addressing the case on its merits, and rendering a court decision, is a crucial tool in raising the question of whether the administrative court should apply remedies to protect violated rights. Simultaneously, the administrative law doctrine posits that an administrative lawsuit itself should be viewed as a means of protecting violated rights. The author observes that doctrinal provisions, grounded in the current administrative procedure law and supported by an analysis of administrative court practice, indicate that an administrative lawsuit significantly influences the activities of an administrative court, particularly in its application of remedies to protect violated rights. Furthermore, some scholarly sources add that the importance of a lawsuit lies in its ability to guide the court’s actions and provide individuals with appropriate guarantees. The author emphasizes that these doctrinal principles align fully with the provisions of the Code of Administrative Procedure of Ukraine, which is considered a conceptually comprehensive procedural document.
