Abstract

Referring to foreign legal systems for the sake of producing a convincing judicial argument has been a custom in judicial decision-making for more than a century. However, a generally accepted theoretical framework for this kind of reasoning is yet to be established. The article suggests that such a framework must answer at least the following three fundamental questions: first, what is the normative relationship, as a matter of principle, between domestic and foreign law?; second, what is the primary motive and functioning of comparative legal reasoning?; and third, what methodological approach enables such reasoning to work in practice? Drawing in particular on linguistic philosophy, as well as recent work on the theory of argumentation, the article outlines a theoretical framework that addresses these questions in order to understand, evaluate and rationalise the use of comparative arguments in legal practice.
