Century City Centre Ltd concluded a lease agreement with Shoprite Checkers Ltd in February 2000 for premises in the Canal Walk Shopping Centre, which was still under construction. The lease commenced on 1 October 2000 when the centre opened. Hyprop Investments Ltd and Ellerine Bros (Pty) Ltd later purchased the shopping centre. A dispute arose regarding clause 7.3 of the lease, which required the tenant to pay a pro rata share of increases in rates measured from the 'initial valuation date'. The appellants contended that this date referred to the valuation operative at lease commencement (when the building was incomplete), while the respondent argued it referred to the first valuation of the completed building. The appellants sought a declarator and payment of over R2 million allegedly due from increased municipal rates.
