Abstract
This paper will examine the role of doctrine in the formation of administrative law. It examines the conditions that seem necessary to ensure the emergence of a new branch of law: a specific set of rules, a specific jurisdiction or procedure by which this set of rules will be implemented and applied, lectures programs enabling the coherent transmission of the subject matter to students and legal professionals, and a network of authors whose thinking is nourished by their interactions and who produce works operating a systematization of the law in this specific field. The paper will primarily consider French and English administrative law, but its implications are not limited to these two legal systems.
