Which law is based on the United States Constitution?

Constitutional Law is indeed based on the United States Constitution. This branch of law encompasses the framework of the government, the rights of individuals, and the relationships between the different branches of government as outlined in the Constitution. It serves as the supreme law of the land, establishing the fundamental principles and rules that govern the country.

Constitutional Law addresses issues such as the distribution of power between the federal and state governments, the protection of civil liberties and rights, and the interpretation of the Constitution itself. Judicial review, where the courts interpret the Constitution and can invalidate laws that are found to be unconstitutional, is a key element of this area of law.

In contrast, other areas of law like Criminal Law, Administrative Law, and Common Law, while they may derive some principles from the Constitution, do not fundamentally stem from the Constitution itself. Instead, Criminal Law governs offenses against the state; Administrative Law deals with regulations created by government agencies; and Common Law is developed through court decisions and precedents rather than being rooted directly in constitutional text.
