概要	Comparative case law analysis is a qualitative legal research method that systematically examines and contrasts judicial decisions from two or more legal systems or jurisdictions. By placing rulings side by side, the method identifies convergences, divergences, and the underlying legal reasoning that shapes how courts address similar legal questions across different national or regional contexts.	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.
