概要	Doctrinal legal research is the foundational methodology of legal scholarship. It systematically identifies, reads, and analyses authoritative legal sources — statutes, case law, constitutional texts, and regulations — to describe, explain, and critique the content and internal logic of legal doctrine. By working within the accepted hierarchy of legal sources, it answers the question 'What is the law?' with analytical rigour and interpretive precision, producing descriptions of settled doctrine and arguments for how ambiguities should be resolved.	Comparative legal analysis is a structured research method that examines how two or more legal systems — whether national, regional, or supranational — address a common legal problem. By placing rules, doctrines, and judicial decisions side by side, researchers identify convergences, divergences, and the underlying societal, historical, and political forces that shape legal solutions. The method is foundational to law reform, harmonisation efforts, treaty drafting, and academic legal scholarship.
