Which federal body is responsible for rule-making through adjudications?

The correct choice identifies federal agencies as the bodies responsible for rule-making through adjudications. Federal agencies, such as the Environmental Protection Agency (EPA) or the Occupational Safety and Health Administration (OSHA), have the authority to create regulations that enforce laws passed by Congress. This process involves rule-making that includes public commentary and often culminates in formal adjudications where agencies interpret laws and make binding determinations regarding specific cases or issues.

Adjudication is the administrative process of resolving disputes within the framework of regulatory enforcement, allowing agencies to apply the rules they create in a fair and just manner. It serves as a means of interpreting the regulations in light of individual situations, ensuring that the rules adapt to the intricacies of various circumstances while maintaining compliance with legislative intent.

In contrast, local governments primarily deal with regulations affecting municipal issues and do not operate at the federal level. State legislatures are responsible for creating state laws rather than federal regulations. International organizations are focused on global issues and cooperation among nations, which is distinctly separate from domestic federal rule-making processes. Thus, it is clear that federal agencies are the entities that engage in rule-making through adjudications.
