First step is to identify and establish the Primary Authority. Primary authorities are the rules of law that are binding upon the courts, government, and individuals including statutes, regulations, court orders and court decisions.
Secondary sources act as supporting tool for legal research as they help to define or situate an issue and gather information on a new or unfamiliar topic, for which Primary source may not an authoritative source. It helps identify legal subjects and develop search strategies and effective keywords and search strings.
