Abstract / Description of output

Defeasible reasoning plays an important part in understanding and modeling legal argumentation. The most commonly used approaches in AI and Law however do not capture legal disputes that are themselves about the legal understanding of defeasibility, argument types that nonetheless play an important role in judicial review or in appeals. We introduce a theory of reasoning about exceptions (or the lack of them) that has been developed by Richard Holton in an attempt to clarify our understanding of the status of ethical norms. We show its potential to add to our theoretical machinery for the analysis of legal reasoning, but also suggest some necessary refinements
