One question arises from the aforesaid facts: why do most of the states decide to adopt the concept that links the right of a citizen to vote with his or her residence? The methodology of voter registration determines the distribution of the polling stations, and accordingly results in the layout of the electoral districts. But, citizens who are abroad on Election Day in the same Council of Europe member states may exercise their right to vote in the diplomatic and consular offices or by mail. However, according to the legislation of the same countries, they would have to return to their country and cast their vote in the polling station located in the municipality where their last residence was before they left the country. Not all of them might be in a position to do so.
