Abstract
This paper presents a quasi-lexicographic judgment aggregation rule based on the hierarchy of judges. We do not assume completeness at both individual and collective levels, which means that a judge can abstain from a proposition and the collective judgment on a proposition can be undetermined. We prove that the proposed rule is (weakly) oligarchic. This is by no means a negative result. In fact, our result demonstrates that with abstentions, oligarchic aggregation is not necessarily a single level determination but can be a multiple-level democracy, which partially explains its pervasiveness in the real world.
