The respondent was the cessionary of two long-term notarial lease agreements concluded between the Borough of Umhlanga and Sycol Properties (Pty) Ltd in 1975 and 1981, in respect of portions of Lot 1066 Umhlanga Rocks. The leases provided for periodic rental revisions calculated at 7% of the value of an area of foreshore land equivalent to the 'floor area' of buildings erected on the leased land, with floor area to be calculated in accordance with the Umhlanga Town Planning Scheme No. 1 as at the date of signature. For many years rental was calculated on a floor area of 15,594.34 m², being the total roofed area measured to the external walls. After discussions in 2008 about a possible sale of the property and a detailed survey undertaken in 2009, the respondent contended that certain areas (public corridors, stairways and entrances) should be excluded in terms of clause 5.1 of the Town Planning Scheme, reducing the relevant floor area to 12,079.10 m². The respondent instituted action seeking recalculation of rental and repayment of alleged overpayments. The High Court upheld the respondent’s interpretation. The municipality appealed to the Supreme Court of Appeal.
