A more thorough explanation: Primary law refers to the body of law that is created by legislative bodies, such as statutes, regulations, and ordinances. It is the main source of law that governs a particular jurisdiction and is considered authoritative and binding. Primary law is distinguished from secondary sources of law, such as legal commentary and case law, which interpret and analyze the primary sources.
Example: The Constitution is considered the primary law of the land in the United States.
