Abstract

This master's thesis analyzes the annulment of administrative decisions within Algerian administrative law. It begins by defining administrative decisions from doctrinal, legal, and judicial viewpoints. The work outlines the key elements of a valid decision: cause, competence, form, object, and purpose. It then explores the legal defects that may lead to annulment, including lack of jurisdiction, procedural errors, and abuse of power. The thesis examines the concept of annulment lawsuits, their characteristics as legal actions, and how they differ from other types of legal remedies. It details procedural requirements such as prior administrative complaints, deadlines, and conditions for admissibility. The research also discusses the termination of administrative decisions—whether naturally, judicially, or through administrative withdrawal. A comparative approach with French administrative law is used throughout the analysis to provide deeper insight into legal practices and principles.
