Any person in office at the appointed day as councillor for any electoral area which is altered by the order shall represent the area as altered until the date on which he would have retired if the order had not been made. Any casual vacancy which exists at the coming into operation of the order or occurs before the appointed day in the office of councillor for any such area shall (except where notice of the election has at the coming into operation of the order already been given) be deemed to have arisen in the representation of the area as altered. Where notice of the election has at the coming into operation of the order already been given the person elected shall represent the area as altered until the date on which he would have retired if the order had not been made.

In relation to the qualification of any person to be elected and to be a member of any county council, district council, London borough council, parish council or community council, of the Greater London Council or the Common Council, or of any committee, joint board or joint committee, the order shall be deemed, for the purposes of section 79 of the Local Government Act 1972, to have been in operation during the whole of the twelve months preceding the relevant day within the meaning of that section.

No person who remains in office after the appointed day as a member of any county council, district council, London borough council, parish council or community council, of the Greater London Council or the Common Council, or of any committee, joint board or joint committee, shall, during the term for which he remains in office, lose his qualification for being a member by reason of the changes of areas made by the order.
