What is different between case law and administrative law?

Case law refers to law established by the outcomes of previous court cases and judicial decisions, forming legal precedents that guide future cases. In contrast, administrative law governs the activities of administrative agencies of government, including rule-making, enforcement, and adjudication. While case law is developed through judicial interpretations and rulings, administrative law is created through statutes and regulations enacted by government agencies. Essentially, case law is derived from the judiciary, while administrative law originates from the executive branch's regulatory processes.
