This study clarifies the concept and manifestations of the principle of legal security, a crucial topic in the philosophy of law with significant influence across all branches of the legal system. While this principle is relevant throughout various legal fields, its importance is particularly pronounced in administrative law. Administrative law not only ensures that public authorities act in accordance with legal procedures, but also guarantees the stability of individuals' legal situations, enhances the regulation of laws and decisions, respects citizens' legitimate expectations, and protects their acquired rights.
The research emphasizes the vital role of legal security in administrative law, especially when administrative courts adopt this principle and adapt its concepts to real-life circumstances. Furthermore, the principle of legal security imposes limitations on the authority of public administration toward individuals in order to provide a certain degree of legal protection and ensure the safeguarding of acquired rights.
To define the essence of legal security, the study is divided into two main sections: the first explores the concept of legal security, while the second addresses its various aspects and its reinforcement through administrative judiciary.
