What is a characteristic of administrative law?

Administrative law is primarily characterized by the rules, regulations, and orders created by various government agencies. These agencies are established by legislative bodies to carry out specific functions and provide detailed legislation on complex issues that require expertise. For instance, environmental protection, occupational safety, and public health are areas often governed by administrative law, with agencies like the Environmental Protection Agency (EPA) or the Occupational Safety and Health Administration (OSHA) issuing rules and regulations that must be followed.

The nature of administrative law is that it plays a crucial role in implementing and enforcing statutory laws created by legislatures. It allows agencies to fill in the details by creating regulations based on their specialized knowledge and experience. This framework ensures that there are informed guidelines governing the public and private interactions regarding complex legal issues, thus making option C the definitive characteristic of administrative law.

In contrast to this, the other options do not accurately reflect the nature of administrative law. It is indeed subject to judicial review, meaning that courts can examine the validity of agency actions. Additionally, administrative law includes regulations created by both federal and state agencies, not just federal regulations. Lastly, it does not derive from common law; rather, it stems from statutes and the authority granted to agencies by legislative bodies.
