A number of international organizations including the
Organization for Security and Co-operation in Europe, the European Commission for Democracy Through Law (the
Venice Commission), the
Commonwealth Secretariat, and the
Electoral Institute of Southern Africa (EISA) have established standards which their members are encouraged to prescribe to. Among these standards the
International Foundation for Electoral Systems (IFES) lists the most common as being Impartiality, Equality, Representativeness, Non-Discrimination and Transparency.
Venice Commission As part of its report,
European Commission for Democracy Through Law: Code of Good Practice in Electoral Matters, Guidelines and Explanatory Reports adopted October 2002, the
Venice Commission proposed the following guidelines: :2.2 Equal voting power: seats must be evenly distributed between the constituencies. ::i. This must at least apply to elections to lower houses of parliament and regional and
local elections: ::ii. It entails a clear and balanced distribution of seats among constituencies on the basis of one of the following allocation criteria: population, number of resident nationals (including minors), number of registered voters, and possibly the number of people actually voting. An appropriate combination of these criteria may be envisaged. ::iii. The geographical criterion and administrative, or possibly even historical, boundaries may be taken into consideration. ::iv. The permissible departure from the norm should not be more than 10%, and should certainly not exceed 15% except in special circumstances (protection of a concentrated minority, sparsely populated administrative entity). ::v. In order to guarantee equal voting power, the distribution of seats must be reviewed at least every ten years, preferably outside election periods. ::vi. With multimember constituencies, seats should preferably be redistributed without redefining constituency boundaries, which should, where possible, coincide with administrative boundaries. ::vii. When constituency boundaries are redefined—which they must be in a single-member system—it must be done: :::- impartially; :::- without detriment to national minorities; :::- taking account of the opinion of a committee, the majority of whose members are independent; this committee should preferably include a geographer, a sociologist, and a balanced representation of the parties and, if necessary, representatives of national minorities.
Commonwealth Secretariat In the publication
Good Commonwealth Electoral Practices: A Working Document, June 1997, the
Commonwealth Secretariat identifies the following practices as necessary for proper delimitation: :20. The delimitation of constituency boundaries is a function occasionally performed by an election commission or otherwise by an independent boundaries commission, and in some cases after a population census. :21. General principles guiding the drawing of constituency boundaries include community of interest, convenience, natural boundaries, existing administrative boundaries and population distribution, including minority groups. There should be no scope for any “gerrymandering”, and each vote should, to the extent possible, be afforded equal value or weight, in recognition of the democratic principle that all those of voting age participate equally in the ballot. :22. It is important that the general public play a part in the whole process and that the political parties also have an opportunity to respond to proposals before they are finalized. Where the size of a particular constituency is markedly out of line with the target “quota” of voters per seat, the reasons should be capable of being readily understood by both the parties and the general public.
IFES In her study sponsored by the
International Foundation for Electoral Systems, Dr.
Lisa Handley recommends the following considerations: • population density • ease of transportation and communication • geographic features • existing patterns of human settlement • financial viability and administrative capacity of electoral area • financial and administrative consequences of boundary determination • existing boundaries • community of interest Also, she suggests that the process should: • be managed by an independent and impartial body that is representative of society, comprising persons with the appropriate skills; • be conducted on the basis of clearly identified criteria such as population, distribution, community of interest, convenience, geographical features and other natural or administrative boundaries; • be made accessible to the public through a consultation process; • be devoid of manipulation of electoral boundaries to favour political groups or political interests; • be conducted by one body; • include all spheres of government, both national and local. ==See also==
