The U.S. Constitution is the most fundamental source of law, establishing the government and guaranteeing rights, but statutes (laws passed by legislatures) and case law (judicial decisions) often affect daily life more directly, regulating everything from behavior (criminal laws) to economic activity (regulations, contracts) and social services, with these laws needing to conform to constitutional principles.
