## Abstract Social choice rules are often evaluated and compared by inquiring whether they satisfy certain desirable criteria such as the __Condorcet criterion__, which states that an alternative should always be chosen when more than half of the voters prefer it over any other alternative. Many of
A family of sets has the equal union property if there exist two nonempty disjoint subfamilies having equal unions and has the full equal union property if, in addition, all sets are included. Both recognition problems are NP-complete even when restricted to families for which the cardinality of eve
