概要	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.	Hermeneutic analysis is a qualitative interpretive method for uncovering the meaning of texts, documents, spoken discourse, or human actions. Rooted in 19th-century biblical and legal scholarship and systematised by Schleiermacher, Dilthey, Gadamer, and Ricoeur, it operates through the hermeneutic circle: the meaning of a part is understood through the whole, and the meaning of the whole is revised as parts are interpreted. The goal is not to measure or code, but to achieve a deepening, dialogic understanding of the object of interpretation.
