In the implementation of LR one sometimes sees that the so-called quota is rounded up
or down to the closest whole number. As will be discussed below, this is an unnecessary
and not very logical rule which may give negative side effects. In Zimbabwe the rule is in
addition unclear because it is not mentioned in the main rule, but is applied to the examples.
The law in its Schedule Eight includes three examples, one for each of the three elections, but
the one for the National Assembly and the Senate are equal. One of the examples goes like this:
Six seats shall be filled, and 236,634 valid votes are cast for seven parties running. The
quota is: Q = 236 634 / 6 = 39 439.
The distribution goes as follows:

Seats for Very Small Parties
One feature of LR is that the results may seem quite arbitrary in some situations. The
method is designed to minimize the deviation from the full proportional result but it does
not differentiate between the small and big parties when doing so. This means that very
small parties may happen to win a seat with very few votes. By modifying the examples of
the act this is illustrated as in tables 3 and 4.
Another example which may be realistic in Zimbabwe is the following. There are a total of
217,288 votes for six seats and seven competing parties.
Q = 36,214.66…

The table below shows the “cost” of the seats, or the number of votes behind each seat
won by a party, using LR and the more robust division method Sainte-Laguë. The latter
method would make the cost more equal, and it would be seen to be much fairer.

Table 26: The cost of each seat won by the parties in terms of number of votes per seat. Using LR
the cost for the seats won by parties A to C is approximately 40,000 and for party D only 8,134,
whereas if Sainte-Laguë had been used the cost for all seats would have been between 26,708 and
39,470.
