The provisions of this Part of this Act shall have effect with respect to—
any tenancy of an agricultural holding granted before 12th July 1984, and
a tenancy granted on or after that date if (but only if)—
the tenancy was obtained by virtue of a direction of the Tribunal under section 39 or 53 below,
the tenancy was granted (following a direction under section 39 below) in circumstances within section 45(6) below,
the tenancy was granted by a written contract of tenancy indicating (in whatever terms) that this Part of this Act is to apply in relation to the tenancy, or
the tenancy was granted otherwise than as mentioned in the preceding provisions of this subsection to a person who, immediately before that date, was a tenant of the holding or of any agricultural holding which comprised the whole or a substantial part of the land comprised in the holding.
In this section "tenant" does not include an executor, administrator, trustee in bankruptcy or other person deriving title from a tenant by operation of law.
