Subject to the following provisions of this section, the amount recoverable under section 159 of this Act in respect of the compensation specified in a compensation notice—
Where, in the case of any land in respect of which a compensation notice has been registered, the Secretary of State is satisfied, having regard to the probable value of any proper development of that land, that no such development is likely to be carried out unless he exercises his powers under this subsection, he may, in the case of any particular development, remit the whole or part of any amount otherwise recoverable under section 159 of this Act; and where part only of any such amount has been remitted, he shall cause the compensation notice to be amended by substituting therein, for the statement of the amount of the compensation, in so far as it is attributable to that land, a statement of the amount which has been remitted under this subsection.
Where, in connection with the development of any land, an amount becomes recoverable under section 159 of this Act in respect of the compensation specified in a compensation notice, then, except where, and to the extent that, payment of that amount has been remitted under subsection (2) of this section, no amount shall be recoverable under section 159 of this Act in respect of that compensation, in so far as it is attributable to that land, in connection with any subsequent development thereof.
No amount shall be recoverable under section 159 of this Act in respect of any compensation by reference to which a sum has become recoverable by the Secretary of State under section 257 of this Act.
