Where under paragraph 11 above a notice to treat is deemed by virtue of a determination of the Lands Tribunal to be a notice to treat for less land or more land than that specified in the notice, the Secretary of State may, within the period of 6 weeks beginning with the day on which the determination is made, withdraw the notice.

If the Secretary of State withdraws a notice to treat under sub-paragraph (1) above, he shall pay the person on whom the notice was served compensation for any loss or expense occasioned to that person by the giving and withdrawal of the notice, such compensation to be determined in case of dispute by the Lands Tribunal.

Where under paragraph 11 above a person is required to sell part only of a house, building or factory or of land consisting of a house with a park or garden, the Secretary of State shall pay him compensation for any loss sustained by him due to the severance of that part in addition to the value of the interest acquired.

A notice to treat shall have the effect which it is deemed to have under paragraph 11(4), (9), (10) or (11) above whether or not the additional land is, apart from that provision, land which the Secretary of State is authorised to acquire compulsorily under this Part of this Act.
