If a substitute in a regional assembly has been appointed as an ordinary member, been elected in another constituency following a re-election, or resigned as a substitute for some other reason, the county administrative board shall, at the request of the chair of the assembly, make new calculations and appoint one further substitute for each member that is affected.

The other candidate who would have been a substitute for a resigning member shall be substitute for another member who is appointed in the place of a member who has resigned.

When making the calculation, the same calculation as for the appointment of substitutes shall be applied. No substitute shall be appointed if it is not possible to appoint a substitute under the first paragraph.
