สรุป	Comparative doctrinal legal research systematically identifies, expounds, and compares the legal rules, principles, and doctrines governing the same problem across two or more jurisdictions. It combines the internal rigour of doctrinal analysis — mapping the authoritative sources of a single legal system — with the external perspective of comparative law, asking whether different legal systems solve the same social problem in similar or divergent ways and why.	Case law analysis is a systematic method for examining judicial decisions to identify binding legal rules, evolving doctrines, and interpretive trends. Rooted in the common law tradition of stare decisis, it requires the researcher to locate the ratio decidendi — the binding reasoning — of each decision, distinguish it from obiter dicta, and trace how that reasoning has been applied, distinguished, or overruled across subsequent cases. The method is fundamental to legal scholarship, litigation strategy, and law reform research.
