3For section 4 (variation of orders, etc.), there shall be substituted the following section—
(1)If it appears to the Secretary of State that, after the time when the amount mentioned in section 2(2)(a) of this Act was determined for any year, the relevant expenditure of local authorities for that year has been or is likely to be substantially increased by reason of—
(a)an increase which has taken place in the level of prices, costs or remuneration, or
(b)the coming into operation of a provision of an enactment passed after this Act,
and that no account was taken of that increase or, as the case may be, the effect of that provision when the amount mentioned as aforesaid was so determined, he may at any time redetermine for that year the amount and portion mentioned in section 2(2)(a) and (b) of this Act and, by an order made in the like manner and subject to the like provisions as a rate support grant order, may increase the amount fixed by the relevant rate support grant order as the estimated aggregate amount of the rate support grants and any element of the grants for that year.
(2)The provisions of sections 2 and 3 of this Act relating to consultation and to a report of the considerations leading to a determination under the said section 2 shall apply to a redetermination under this section as they apply to a determination under that section; and the Secretary of State may, if he considers it practicable, incorporate an order under this section in a rate support grant order.
(3)In redetermining under this section the amount and portion mentioned in section 2(2)(a) and (b) of this Act, the Secretary of State—
(a)shall take into account not only the effect of the increase referred to in paragraph (a) of subsection (1) above or, as the case may be, the provision referred to in paragraph (b) of that subsection, but also any future variation in the level of prices, costs and remuneration current at the time of the redetermination which in his opinion will result from any such decisions as are referred to in section 2(3)(d) of this Act, and
(b)except in the case of a change resulting from the coming into operation of any enactment passed after this Act, shall take no account of any change, as compared with the situation at the time that amount and that portion were determined for the purposes of the relevant rate support grant order, in the demand for services giving rise to relevant expenditure, in the need for developing those services or in the extent to which those services have been developed.
(4)An order made under subsection (1) above in respect of any year shall specify the actual (and not the estimated) aggregate amount of the resources element for that year.
(5)If, in a case where the Secretary of State proposes to make an order under subsection (1) above in respect of any year, it appears to him that, apart from any provision made by virtue of this subsection, the effect of the order and of any other order under subsection (1) above which he considers likely to be made in respect of that year would be that the ratio between the actual aggregate amount of the resources element for that year and the aggregate amount of the needs element for that year would be significantly different from the ratio (in this subsection referred to as " the expected ratio") between the estimated aggregate amount of the resources element for the year, as fixed by the relevant rate support grant order, and the aggregate amount of the needs element, as so fixed, he may in the order under subsection (1) above—
(a)specify as the aggregate amount of the resources element for that year such amount as, in his estimation, will secure that (taking account of the effect of any further orders likely to be made under subsection (1) above in respect of that year) the ratio which the amount so specified will bear to the aggregate amount of the needs element for that year will be the expected ratio ; and
(b)in order to secure that the total amount paid in respect of the resources element to local authorities entitled to payments in respect of that element does not exceed the amount specified as mentioned in paragraph (a) above, make provision varying the amount payable to each such authority in respect of that element.
(6)Without prejudice to subsection (5) above, an order made under subsection (1) above with respect to any year may, as respects that year, vary the matters prescribed by the relevant rate support grant order.
(7)In this section " relevant expenditure" has the same meaning as in section 2 of this Act.”.
