(1) A provision in a
retail shop lease —
(a) to
the effect that the tenant is obliged to furnish, or permit the landlord or
his agent to gather, figures or statements relating to the turnover of the
business; or
(b) to
the effect that the landlord is entitled to be furnished with figures or
statements relating to the turnover of the business,
is void unless the
figures or statements are required for the purpose of determining rent either
in whole or in part by reference to the turnover of the business.
(2) Where a retail
shop lease contains a provision of a kind referred to in subsection (1) and
the figures or statements to which the provision applies are required for the
purpose of determining rent either in whole or in part by reference to the
turnover of the business, that provision ceases to have effect upon those
figures or statements being no longer required for the purpose.
