Which is considered the highest source of law?

Constitutional law is regarded as the highest source of law because it establishes the fundamental principles and framework of a legal system. The constitution serves as the supreme law of the land, meaning that any laws or regulations created by legislatures or administrative agencies must be in accordance with the constitutional provisions. This hierarchy ensures that any conflicting laws can be challenged and invalidated if they do not conform to the constitution. In the case of Minnesota and in the United States as a whole, constitutional law provides the foundation for all other legal sources, which include statutory law, case law, and administrative law. Statutory laws are enacted by legislative bodies, case law is established through court decisions interpreting laws, and administrative law involves regulations created by governmental agencies—all of which must ultimately align with constitutional law to be valid.
