Consensus rules based on decisive families: The case of hierarchies

The notion of a decisive family of voters has played an important role in the analysis of various consensus functions defined on preference profiles. This role remains when the domain shifts to profiles of hierarchical classifications. The main result of this paper is a characterization of consensus rules defined on hierarchies where the output clusters are determined by a decisive family of sets.
