Several amendments have been made to specify the procedure for establishing electoral districts (by the CEC) and election precincts (by the DECs) (see Chapter III). However, the Election Code still does not contain any provisions on a maximum deviation from the average ratio of registered voters (or inhabitants or adult citizens) per single-member district. Such a legal provision, however, is very common by international standards and was recommended by international experts. The principle of equal suffrage can be severely violated if the sizes of single-member constituencies (in terms of the number of registered voters) varies substantially. It would be important to define the maximum deviation permitted by law and to set out the necessary procedure to fulfil the requirement.
