    abstract = "We present the design of a system for making sense of conflicting rules expressed in a fragment of the prominent controlled natural language ACE, yet extended with means of expressing defeasible rules in the form of normality assumptions. The approach we describe is ultimately based on answer-set-programming (ASP); simulating existential quantification by using skolemization in a manner resembling a translation for ASP recently formalized in the context of {\ensuremath{\exists}}-ASP. We discuss the advantages of this approach to building on the existing ACE interface to rule-systems, ACERules."
