Compensation for compliance with condition

(1) Whenever a condition is attached to or inserted in a permission or a prohibition and the value of any property is reduced by the due and proper performance or observance of such condition, the provisions of this Part in relation to compensation payable by the Central Authority shall apply. (2) Upon the coming into operation of the scheme in connection with which such permission or prohibition was granted or made, the compensation payable shall be as if such reduction in value had been occasioned by a restriction on the user of the property affected by a provision contained in the (3) Subsections (1) and (2) of this section shall not apply or have effect where the condition referred to in subsection (1) is of such nature that if the scheme referred to in subsection (2) had been in operation when such condition was imposed, the condition could have been enforced by a provision in the scheme and no compensation would have been payable under this Part on account of or arising from the coming into operation of such provision.
