(1)The following rules apply for determining the effective duration of a lease for the purposes of this Chapter.
Rule 1: Where the effective duration of a lease is being determined after the date on which the lease has for any reason come to an end, the duration is taken to have extended from its commencement to that date.
Rule 2: Where the terms of the lease include provision for the determination of the lease by notice given either by the landlord or by the tenant, the lease is not to be treated as granted for a term longer than one ending at the earliest date on which it could be determined by notice.
Rule 3: A lease is not to be treated as having been granted for a term longer than one ending on a date before the end of the term for which the lease was granted, if the terms of the lease or any other circumstances make it unlikely that the lease will continue beyond that date.
(2)Rules 2 and 3 are subject to Rule 1.
(3)Rules 2 and 3 apply in accordance with circumstances prevailing at the time of the determination.
(4)In this section, in relation to Scotland, “term”, where referring to the duration of a lease, means period.”
