Abstract

This paper studies the modelling of legal reasoning about evidence within general theories of defeasible reasoning and argumentation. In particular, it is studied how Wigmore's method for charting evidence and its use by modern legal evidence scholars can be exploited by modern visualisation software for argumentation, and how a formal account of the method can be given in terms of logics for defeasible argumentation. Two notions turn out to be crucial, viz. argumentation schemes and empirical generalisations.
