“20. The 1999 Act can thus be seen as applying principles analogous to those in [the cases decided before the 1988 Act] to a hypothetical lease in which the tenant bore the obligation to put the hereditament in repair. In my view the Court of Appeal goes too far in interpreting the 1999 Act as completely displacing the reality principle in relation to both the physical state and the mode of occupation of a hereditament which is undergoing redevelopment. The 1999 Act, by introducing the assumption of reasonable repair at the outset of the hypothetical tenancy ("the repair assumption"), is not addressing the question of whether the premises were capable of beneficial occupation, which, in the context of a building undergoing redevelopment, is a logically prior question. Thus the repair assumption (para 2(1)(b)) applies to matters affecting the physical state of the hereditament (para 2(7)(a)) but not to the mode or category of occupation of the hereditament (para 2(7)(b)).”
“… that there is no basis for applying the assumption in para 2(1)(b) to override the reality principle and to create a hypothetical tenancy of the previously existing premises in a reasonable state of repair. This is both because a building under redevelopment, like a building under construction, is incapable of beneficial occupation and, in any event, the hypothetical landlord of a building undergoing redevelopment would normally not consider it economic to restore it to its prior use.”
“A programme of reconstruction works may include stripping out what was there before. The work undertaken by the building contractors in both stripping out what was there before and the new work will constitute the programme. However mere stripping out on its own does not of itself constitute or evidence a programme of reconstruction but rather simple damage, putting the hereditament in a state of disrepair.”
