Which of the following does not fall under Federal Law?

To understand why the correct answer is that all of the listed items do not fall under Federal Law, it's important to clarify what constitutes federal law.

Congressional statutes, executive orders, and treaties are all established components of federal law. Congressional statutory law is created by legislative acts of Congress, executive orders are directives issued by the President to manage the operations of the federal government, and treaties are formal agreements made with other countries that require Senate approval. Each of these elements is vital to how federal law is shaped and enforced.

Furthermore, laws enacted by the Environmental Protection Agency (EPA) are also grounded in federal law, as the EPA is a federal agency responsible for implementing and enforcing regulations based on congressional statutes, particularly those related to environmental protection.

Given this context, it becomes clear that each option represents an aspect of federal law rather than entities that do not fall under it. Thus, stating that all of the options fall outside federal law is incorrect, as they are indeed governed by federal law.
