Where any of the land specified in a general vesting declaration has become vested in an acquiring authority by virtue of Part III of this Act, the acquiring authority shall be liable to pay the like compensation, and the like interest on the compensation agreed or awarded, as they would have been required to pay if they had taken possession of the land under section 11(1) of the Compulsory Purchase Act 1965.
Where by virtue of an agreement under section 8A or 8B different interests in the land vest in the acquiring authority on different dates, subsection (1) does not give rise to any liability in relation to an interest until that interest becomes vested.
Section 22 of the Compulsory Purchase Act 1965 and Schedule 2 to that Act (absent and untraced owners) shall not apply to the compensation to be paid for any interest in land in respect of which a notice to treat is deemed to have been served by virtue of Part III of this Act.
