13Effect of change of circumstances on instrument of government
(1)Any instrument of government to which this Act applies shall (subject to subsection (2) below and paragraph 3(2) of Schedule 2 to this Act) make such provision as is appropriate having regard to all the circumstances of the school as at the date on which the instrument is made.
(2)Where a proposal of a kind mentioned in section l1(2)(a) or (b) of this Act has been implemented in relation to any school, the number of registered pupils at the school shall, for the purposes of subsection (1) above and until the number of registered pupils at the school reaches the maximum number of pupils provided for by the proposal, be deemed to be that maximum number.
(3)Where subsection (2) applies in relation to any school, the local education authority or (in the case of a proposal under section 13(1)(b) of the 1980 Act) the governing body may determine that it shall cease to apply (but without prejudice to its operation in relation to the implementation of any further proposal).
(4)Where the effect of any subsequent change in the circumstances of a school is that the provision made by the instrument of government for the school differs in any respect from the provision which a new instrument of government would be required to make, it shall be the duty of the local education authority (subject to subsection (7) below): —
(a)to vary the instrument of government in such manner as is required to remove any such difference ; or
(b)to make a new instrument of government.
(5)Any instrument of government to which this Act applies may make provision which would be appropriate in the event of such a change in the circumstances of the school as is anticipated by that provision (including in particular a change in the number of registered pupils at the school).
(6)No provision made by any such instrument in anticipation of a change in the number of registered pupils at the school shall have effect before it is established, by a review under section 11 of this Act, that a new instrument of government for the school in question would be required to make that provision.
(7)For the purposes of subsection (4) above, any change in the number of registered pupils at a school occurring after the instrument of government for the school is made, or (as the case may be) varied, may be disregarded until a review under section 11 of this Act establishes that the provision made by the instrument differs in any respect from the provision which a new instrument of government for the school would be required to make.
(8)Where subsection (2) above has applied in relation to any school but the local education authority or (as the case may be) governing body have subsequently determined that it should cease to apply, subsections (4) and (7) above shall have effect as if a change in the number of registered pupils at the school had occurred at the time when that determination was made.
(9)Subsections (6) and (7) above do not apply to aided or special agreement schools.
