Unless you are an expert in a particular country’s laws, or subject area, you should always start your research using secondary sources. This is because secondary sources will gather together information on a subject for you, and may provide you with names of, or citations to any of the following: statutes, cases, regulations (or statutory instruments as they referred to in many countries), or delegated legislation.
