Supplementary provisions as to transitional relief
5.—(1) Where the capital value ascribed to a specified hereditament in the capital value list is altered after 1st April 2007, then for the purpose of determining any reduction of the unadjusted amount under Article 4—
(a)if the capital value is increased, such increase shall be disregarded; and
(b)if the capital value is reduced, the unadjusted amount in relation to any period after reduction shall be the sum which would have been chargeable apart from this Order in respect of that hereditament as a result of that reduction.
(2) Where, on 1st April 2007, a hereditament is not a specified hereditament which is included in the capital value list, such a hereditament shall be deemed not to be a specified hereditament in the capital value list for the purposes of Article 2 only by virtue of the fact that a capital value has been ascribed to it in the new capital value list after 1st April 2007.
