If the acquiring authority do not within the period of two months beginning with the date of service of a counter-notice under section 55 above agree in writing to accept the counter-notice as valid, the claimant or the authority may, within two months after the end of that period, refer it to the Upper Tribunal; and on any such reference the Tribunal shall determine whether the claim in the counter-notice is justified and declare the counter-notice valid or invalid in accordance with its determination of that question.
Where a counter-notice is accepted as, or declared to be, valid under subsection (1) above then, if before the end of twelve months after it has been so accepted or declared the claimant has given up possession of every part of the agricultural holding to the acquiring authority—
Where the claimant gives up possession of an agricultural holding to the acquiring authority as aforesaid but the authority have not been authorised to acquire the landlord's interest in, or in any of, the part of the holding to which the notice of entry did not relate ("the land not subject to compulsory purchase")—
Where a tenancy is terminated by virtue of subsection (3)(c) above, section 72 of the Agricultural Holdings Act 1986 (landlord's right to compensation for deterioration of holding) shall have effect as if subsection (4) of that section required the landlord's notice of intention to claim compensation to be served on the acquiring authority and to be so served within three months after the termination of the tenancy.
