No person shall carry out any new development to which this section applies, on land in respect of which a notice (hereafter in this Part of this Act referred to as a " compensation notice") is registered under section 158 of this Act, until such amount (if any) as is recoverable under this section in respect of the compensation specified in the notice has been paid or secured to the satisfaction of the Secretary of State.
Subject to the following provisions of this section, this section applies to any new development—
This section shall not apply to any development by virtue of subsection (2)(c) of this section if, on an application made to him for the purpose, the Secretary of State has certified that, having regard to the probable value of the development, it is not in his opinion reasonable that this section should apply thereto.
Where the compensation specified in the compensation notice became payable in respect of the imposition of conditions on the granting of permission to develop land, this section shall not apply to the development for which that permission was granted.
