Voting districts The municipality is the voting district unless there are grounds for dividing it into several voting districts. The council shall determine the voting districts. In making the decision, the changes in the municipal division coming into effect from the beginning of the following calendar year shall be taken into consideration. The council shall also determine to which voting district those persons belong who do not have a registered place of residence in the Population Information System.   The decision regarding the voting districts enters into force on October 15 provided the decision is made and notified to the local register office by April of the same year in the manner it specifies. If a decision is made or notified to the local register office later, it enters into force on October 15 the following year.   If a decision to change the municipal division has been made after the decision regarding the voting districts, the council or, if a ministry has made the decision, the municipal board shall without undue delay review the voting district division.   The decision regarding the voting districts which has been notified to the local register office shall be observed regardless of an appeal submitted to the Administrative Court, unless the Administrative Court rules otherwise, until the appeal has been settled. The decision of the Administrative Court regarding the appeal is not subject to appeal.
