Which of the following defines secondary authority in legal contexts?

Secondary authority refers to sources of law that analyze, interpret, or comment on primary legal sources, such as statutes, cases, and regulations. These sources help clarify the law or provide additional context, but they do not have the binding legal authority of primary sources.

In this context, a respected treatise on tort law serves as secondary authority because it provides scholarly analysis and expert insights into principles of tort law, contributing to the understanding of the topic without being the law itself. Treatises, law review articles, and other legal commentaries fall into this category and are often used by practitioners and scholars alike to support legal arguments or understand complex areas of law.
