Administrative law vs. public administration law

Public administration has to do with the practical management and direction of the various organs of the State and the execution of state policies by the executive and administrative officers entrusted with such functions.

Public administration is the implementation of government policy and also an academic discipline that studies this implementation and prepares civil servants for working in the public service. https://en.wikipedia.org/wiki/Public_administration.

Administrative law is the body of law that governs the activities of administrative agencies of government. Government agency action can include rule making, adjudication, or the enforcement of a specific regulatory agenda. Administrative law is considered a branch of public law. https://en.wikipedia.org/wiki/Administrative_law.

The subject matter of administrative law is public administration. Since administrative law covers all laws that concern public administration, the two are apparently synonymous with each other. However, a highly technical distinction is observed between them. The true field of administrative law refers only to the external aspect of public administration. Thus, administrative law is the narrower branch but it constitutes the bulk of the law of public administration.

Administrative law, the legal framework within which public administration is carried out. It derives from the need to create and develop a system of public administration under law, a concept that may be compared with the much older notion of justice under law. Since administration involves the exercise of power by the executive arm of government, administrative law is of constitutional and political, as well as juridical, importance. https://www.britannica.com/topic/administrative-law.
