Representation and reasoning over legal rules is an important application domain and a number of related approaches have been developed. In this work, we investigate legal reasoning in practice based on three use cases of increasing complexity. We consider three representation and reasoning approaches: (a) Answer Set Programming, (b) Argumentation and (c) Defeasible Logic. Representation and reasoning approaches are evaluated with respect to semantics, expressiveness, efficiency, complexity and support.
