Where it appears that serious inconveniences have been caused the voters by the size or shape of an election district, or that certain districts contain an unreasonably large or small number of voters in comparison with other districts, or that a change is necessary because of a change in ward lines, the county board may revise or readjust the election districts in the municipality, without regard to whether a readjustment is authorized by section 2 or 3 of this act.
