Administrative law is primarily created by which of the following?

Administrative law is primarily created by administrative agencies because these organizations are empowered by legislative bodies to implement and enforce specific statutes. These agencies possess the authority to create rules, regulations, and guidelines within their areas of expertise, thereby establishing a framework for compliance that governs the conduct of individuals and organizations.

Administrative agencies, such as environmental protection or public health agencies, develop detailed rules and procedures that have the force of law, allowing them to carry out the objectives set forth in the enabling legislation. This power to create regulations makes administrative law distinct from other forms of law, which primarily arise from legislative or judicial actions.

Legislative bodies create laws, but they often delegate the authority to administrative agencies to execute and enforce these laws, particularly when specialized knowledge or ongoing oversight is required. Courts interpret laws and can develop case law, but they do not create administrative law in the same manner as agencies. International treaties also contribute to the body of law but are not a source of domestic administrative law. Thus, the most accurate source of administrative law is through the actions and regulations of administrative agencies.
