Answer:
This statement is not correct. The law is a practical and theoretical discipline, that is, it is made up of both the application of laws and the different judicial procedures as well as the theoretical content of the laws, which give their clauses sociological and technical support.
Thus, the different theories of law are applied by legislators when drafting a law, and those same theories are used by congressmen when debating whether or not to approve those laws.
In addition, theories are also used in other areas of law, such as criminal law, where doctrine and jurisprudence develop and adapt theories to different judicial situations. For example, the theory of law by which detainees must know their rights before declaring, the Miranda Warning, arises from a theory developed by the Supreme Court under an interpretation of the Fifth Amendment.
