When should a legal researcher consider reviewing a headnote?

A legal researcher should consider reviewing a headnote when wishing to attach a key number to their research. Headnotes are brief summaries or annotations of legal principles that appear at the beginning of a case, often categorized by key numbers that organize legal topics effectively. This allows researchers to connect cases with specific legal issues, as the key number system is a classification method used primarily in legal research.

By reviewing a headnote, the researcher can quickly ascertain the legal topics addressed in the case, making it easier to find additional cases that discuss similar issues. This practice enhances the efficiency of legal research by facilitating access to an organized body of case law relevant to specific legal questions or subjects. Understanding how to utilize headnotes and key numbers is pivotal in navigating legal databases and ensuring comprehensive legal research.
