Qualitative Choice Logic (QCL)is a convenient tool for representing and reasoning with "basic" preferences. However, this logic presents some limitations when dealing with complex preferences that, for instance, involve negated preferences. This paper proposes a new logic that correctly addresses QCL's limitations. It is particularly appropriate for handling prioritized preferences, which is very useful for aggregating preferences of users having different priority levels. Moreover, we show that any set of preferences, can equivalently be transformed into a set of normal form preferences from which efficient inferences can be applied.
