Every piece of legal knowledge originates from either primary or secondary sources. The law is explained in primary sources. Constitutions, treaties, and other legally binding international agreements, legislation as adopted and codified, agency rules, court judgments, agency adjudicative body rulings, executive orders, presidential proclamations, and specific government instructions are examples of primary sources (such as some military orders, including some verbal ones).
The hierarchy of authority for court rulings, also known as case law, goes from most authoritative to least authoritative.
