Advantages of List PR

In addition to the advantages attached to PR systems generally, List PR makes it more likely that the representatives of minority cultures/groups will be elected. When, as is often the case, voting behaviour dovetails with a society’s cultural or social divisions, then List PR electoral systems can help to ensure that the legislature includes members of both majority and minority groups. This is because parties can be encouraged by the system to craft balanced candidate lists which appeal to a whole spectrum of voters’ interests. The experience of a number of new democracies (e.g. South Africa, and Indonesia) suggests that List PR gives the political space which allows parties to put up multiracial, and multi-ethnic, lists of candidates. The South African National Assembly elected in 1994 was 52 per cent black (11 per cent Zulu, the rest being of Xhosa, Sotho, Venda, Tswana, Pedi, Swazi, Shangaan and Ndebele extraction), 32 per cent white (one-third English-speaking, two-thirds Afrikaans-speaking), 7 per cent Coloured and 8 per cent Indian. The Namibian Parliament is similarly diverse, with representatives from the Ovambo, Damara, Herero, Nama, Baster and white (English and German-speaking) communities.
List PR makes it more likely that women will be elected. PR electoral systems are almost always more friendly to the election of women than plurality/majority systems. In essence, parties are able to use the lists to promote the advancement of women politicians and allow voters the space to elect women candidates while still basing their choice on other policy concerns than gender. As noted above, in single-member districts, most parties are encouraged to put up a ‘most broadly acceptable’ candidate, and that person is seldom a woman. In all regions of the world, PR systems do better than FPTP systems in the number of women elected, and 15 of the top 20 nations when it comes to the representation of women use List PR. In 2013, the number of women representatives in legislatures elected by List PR systems was 6.3 percentage points higher than the average of 21.8 per cent for all legislatures, while that for legislatures elected by FPTP was 2.8 percentage points lower.

Disadvantages of List PR

In addition to the general issues already identified relating to PR systems, the following additional disadvantages may be considered:

Weak links between elected legislators and their constituents. When List PR is used, and particularly when seats are allocated in one single national district, as in Namibia or Israel, the system is criticized for destroying the link between voters and their representatives. Where lists are closed, voters have no opportunity to determine the identity of the persons who will represent them and no identifiable representative for their town, district or village, nor can they easily reject an individual representative if they feel that he or she has performed poorly in office or is not the kind of person they would want representing them – e.g., warlords in countries such as Bosnia or Afghanistan. Moreover, in some developing countries where the society is mainly rural, voters’ identification with their region of residence is sometimes considerably stronger than their identification with any political party or grouping. This criticism, however, may relate more to the distinction between systems in which voters vote for parties and systems in which they vote for candidates.
Excessive entrenchment of power within party headquarters and in the hands of senior party leaderships—especially in closed-list systems. A candidate’s position on the party list, and therefore his or her likelihood of success, is dependent on currying favour with party bosses, while their relationship with the electorate is of secondary importance. In an unusual twist to the List PR system, in Guyana parties publish their list of candidates not ranked but simply ordered alphabetically. This allows party leaders even more scope to reward loyalty and punish independence because seats are only allocated to individuals once the result of the vote is known.
The need for some kind of recognized party or political groupings to exist. This makes List PR particularly difficult to implement in those societies which do not have parties or have very embryonic and loose party structures, for example, many of the island countries of the Pacific. While technically possible to allow independent candidates to run under various forms of PR, it is difficult and introduces a number of additional complications, particularly as relates to wasted votes.
