25.—(1) A local education authority may in the circumstances described in paragraph (2) redetermine a former grant-maintained or grant-maintained special school’s budget share for the financial year beginning on 1st April 2005 to take into account changes in that school’s non-domestic rates liability or to correct errors in data supplied by the head teacher or governing body of the school, by reference to which the school’s maintenance grant (as a grant-maintained or grant-maintained special school) was determined for any financial year beginning on or before 1st April 1998.
(2) The circumstances referred to in paragraph (1) are that—
(a)such matters have not already been taken into account in any determination or redetermination of that school’s budget share within the meaning of the 1996 Act or the 1998 Act or its maintenance grant (as a grant-maintained or grant-maintained special school);
(b)such redetermination as is proposed could have been made in the preceding financial year in question in relation to a school maintained by the authority under the terms of the authority’s scheme within the meaning of the 1996 Act in force in that year; and
(c)any increase or decrease in the amount of the school’s budget share to take into account changes in the school’s non-domestic rates liability does not exceed the change in the school’s net liability in respect of rates.
(3) In so far as a determination under paragraph (1), arising from adjustments relating to the financial year beginning on 1st April 1998, would require the amount that would otherwise be the budget share of the school to be reduced, it may not be reduced by an amount greater than the amount by which the school’s maintenance grant for that financial year determined in accordance with regulation 9 (transitional funding) of the 1998 Regulations could have been reduced.
(4) In so far as a determination under paragraph (1), arising from adjustments relating to the financial year beginning on 1st April 1998, would require the amount that would otherwise be the budget share of a former grant-maintained or grant-maintained special school to be increased, there shall be deducted from that increase any amount for transitional funding determined in respect of the school in the financial year beginning on 1st April 1998 under regulation 9 (transitional funding) of the 1998 Regulations.
