2(1)In any case where—U.K.
(a)before 19th March 1985 there was a DLT disposal which was a deemed disposal, and
(b)by virtue of any provision of the 1976 Act, liability for development land tax on all or any of the realised development value which accrued on the DLT disposal stands deferred immediately before that date and, accordingly, is extinguished under section 93(3) of this Act,
then, except as respects the interaction of the DLT disposal with a CGT disposal or trading disposal occurring before 19th March 1985, for the purposes of Part I of Schedule 6 to the 1976 Act (interaction of development land tax with other taxes) so much of the realised development value as is referable to the deferred tax shall be assumed not to have accrued on the DLT disposal and, accordingly, no sum shall be regarded as being available or allowable as a deduction under any provision of that Part by virtue of that amount of realised development value.
(2)If, in a case falling within paragraphs (a) and (b) of sub-paragraph (1) above, liability for only some of the tax which accrued on the DLT disposal stands deferred as mentioned in paragraph (b), any reference in that sub-paragraph to the amount of realised development value which is referable to the deferred tax is a reference to that proportion of the whole of the realised development value accruing on the DLT disposal which the tax the liability for which stands so deferred bears to the whole of the tax the liability for which arose on the DLT disposal.
(3)In this paragraph, “DLT disposal”, “CGT disposal” and “trading disposal” have the meaning assigned by section 34(3) of the 1976 Act.
