Secondary sources are materials written about the law by experts and which assist our understanding of primary law. A secondary legal source is any legal resource that is not the law.
Secondary sources are always persuasive and are not used as legal authority, but they have been cited by courts for persuasive value. More importantly, secondary sources are a research tool that can help legal researchers understand the area of law they are researching and even connect them to valuable primary resources.
Secondary Sources save you time.
It depends.
