This involves the study of legal families or engagement in grand systems debate. The examples of legal family are: civil law, common law, religion-based laws (Hindu Law, Islamic Law, Talmudic law), and regional laws (Japanese law, African law, and Chinese Law). Differences prevail amidst legal families, whereas similarities prevail amidst member legal systems of each legal family. Hence, a macro-comparison may bring out differences or similarities depending upon the affinity or non-affinity of the systems to legal family. Five factors central to the legal family—background, predominant characteristic, distinctive legal institution, kinds of sources, and ideology—are to be looked at in a holistic manner. Study of non-legal materials—geography, history, sociology, economy, politics, and culture—provides valuable input for macro-comparison. For example, a glimpse of differential positions on these matters in India and Japan in the matter of ethnic minorities clarifies the reasons and justifications for different legal approaches. The aim to realize human rights and the working of democratic structure may provide factors of similarities. Ignoring these aspects weakens CLR.
