Detailed Commentary on Sections in Part 6 Schedule 1: Alteration of Assembly Electoral Regions Paragraph 9(6)
619.Taking the above example again, if the number of electors in electoral region A is 130,000, and the number of constituencies in the region is 10, 130,000 is divided by 13 (10 + 3), giving a result of 10,000.
620.The results which this calculation produces for each region are then compared. The residual seats are then allocated. It is desirable that the residual seats are allocated to the regions in respect of which this calculation produced the highest results, and this should be taken into account when the residual seats are allocated.
621.If an electoral region is not allocated a residual seat, the number of regional seats it has will just be one fifth of the next highest figure to the total number of regional seats which can be divided exactly by 5. In the example of 19 regional seats, the next highest number would 15, which when divided by 5 gives 3 regional seats.
