20 CHAPTER 2. UNIFIED DESCRIPTION OF ELECTORAL SYSTEMS Let us examine more closely how the mechanism works, after each ballot, at an arbitrary node q of the district tree T. Recall that q represents either a district, or a region, or the whole nation (when q is the root of T}. , q represents a district) or from a previous level of the tree. The votes are attributed either to lists or to candidates or to rankings, depending on the ballot structure, as discussed above. Then a filter selects the active votes that are actually used to assign seats at the level of hierarchy under consideration.

With reference to a given district j, we classify ballots into four different groups: • list ballots, containing a single list L^; • preference ballots, containing a subset of at most r candidates in Kj, where the integer r is fixed in advance and is called the number of preferences; • cumulated ballots, containing a bag (subset with possibly repeated elements) of candidates in Kj. Each elector is granted a "stock" of at most r preferences, which may be arbitrarily distributed among no more than r candidates in Kj.

The set of lists are the cartels associated with the partition 7rq. 7, where n = 8, k = 9, m = 3). Therefore, a cartel is a cross section of the set £ of all lists and is completely specified by (1) a subset Ch of parties; (2) a subset Jq of districts. In order to provide a uniform description of the electoral engine, we shall make the assumption that, at the bottom level (district level) of the tree T, every cartel consists of a single list. 1.
