The respondent (Rand Water Board) instituted action against twenty-seven defendants who were owners of units in Klub 40, a Sectional Titles Scheme built on part of the farm Anniesrus in the Sasolburg district, riparian to the Vaal River. The respondent sought demolition of habitable buildings erected below the defined flood control line without its written consent. The members of Klub 40 were originally tenants who decided to convert to a sectional title scheme, registered on 30 January 1997. At a meeting on 7 May 1996, agreement was reached regarding illegal structures. Du Plessis, the respondent's legal adviser, granted conditional approval on 5 June 1996 and placed an approval stamp on the plan. The first appellant acquired unit 18 on 8 October 1998 and unit 19 on 2 August 2002. The property fell within the Vaal River Barrage area governed by the Vaal River Complex Guide Plan, deemed to be a Regional Structure Plan under s 37(2)(a)(i) and (ii) of the Physical Planning Act 125 of 1991. Annexure C clause 2.2 required written consent from Rand Water Board for any habitable buildings or structures below the flood control line. Most defendants settled; only the first appellant and others persisted in resistance.
