As mentioned above in Chapter III.B.1. on “Principles and international standards”, the Code of Good Practice in Electoral Matters assumes that changes to constituency boundaries should be made taking into account the opinion of a committee, the majority of whose members are independent, preferably including a geographer, a sociologist and a balanced representation of political parties and, if necessary, representatives of national minorities.^[49] This standard shows that solid factual bases for the redrawing of the constituencies must be collected and taken into account for the redrawing of constituency boundaries, even in cases where states have not established a special committee for this purpose.[50] Independent experts, in particular geographers and sociologists, should in any case be involved in the process, as well as a balanced representation of political parties. The procedure followed by the Hungarian lawmakers failed to meet these standards, and it thus failed to make the actual background and reasons for the change transparent, to create trust and to ensure a well-founded and non-politically motivated legislative solution.
