Which of the following is NOT included in enacted law?

The concept of enacted law typically refers to laws that are officially approved and established by legislative bodies or governing authorities. In this context, enacted law encompasses statutory law, administrative regulations, and constitutional law, all of which are formal laws created through established political and legal processes.

Statutory law is created by legislative bodies, which pass laws that must be followed. Administrative regulations are established by governmental agencies and are also considered a form of enacted law because these regulations have been formally enacted under the authority granted by the legislative body. Constitutional law encompasses the foundational principles and structures outlined in a constitution, which has also gone through a formal enactment process.

On the other hand, case law results from judicial opinions and decisions made by courts. It is not created or enacted by legislative bodies but rather developed through the interpretation and application of existing laws and statutes by judges. Therefore, case law does not fit within the category of enacted laws, making it the correct choice for the question regarding which is NOT included in enacted law.
