Which of the following accurately defines constitutional law?

The definition of constitutional law focuses specifically on the interpretation and application of the U.S. Constitution as well as state constitutions. This branch of law addresses issues related to the powers of government, the rights of individuals, and the principles of governance as outlined in these foundational documents.

Constitutional law is concerned with the framework of government, including how laws are crafted, enforced, and interpreted in the context of constitutional guarantees. It plays a crucial role in protecting civil liberties and ensuring the proper balance of power among the branches of government, making it distinct from other areas of law such as statutory law, administrative regulations, or common law, which do not directly derive from the Constitution itself.

The other options address different aspects of law: legislation refers to laws passed by legislative bodies; administrative regulations are rules created by governmental agencies; and common law stems from judicial decisions over time. Each plays an important role within the legal system, but they do not encapsulate the essence of constitutional law as defined.
