Final answer:
The three types of law that regulate agency relationships are administrative regulations, statutes or legislative enactments, and case law or judicial decisions. Administrative regulations come from agencies like the FCC and FTC and are included in the CFR, statutes are laws passed by Congress, and case law consists of court decisions.
Step-by-step explanation:
The three types of law that regulate agency relationships include administrative regulations, statutes or legislative enactments, and case law or judicial decisions.
Administrative regulations are issued by executive agencies such as the Federal Communications Commission (FCC) and the Federal Trade Commission (FTC), and form part of the Code of Federal Regulations (CFR). These regulations are designed to implement and enforce legislation, and they derive their authority from the executive branch of the government.
Statutes or legislative enactments are laws passed by legislatures, like Congress, and form a substantial body of law governing agency actions and relationships. They set forth the scope of an agency's powers and limitations.
Last but not least, case law or judicial decisions are legal principles and rules of conduct based on past court decisions. They help interpret and apply statutes and regulations, and also fill in gaps where regulations or statutes might be silent.
