Representation of Case Law as an Argumentation Framework

Since their introduction by Dung, Argumentation Frameworks have pro- vided a fruitful basis for studying reasoning in defeasible contexts, including law. As yet, however, no realistic body of case law has been represented as an Argumenta- tion Framework. In this paper we develop an Argumentation Framework of a much discussed body of case law, and draw attention to a number of questions concern- ing approaches to reasoning with cases in AI and Law that can be informed by this exercise.
