The Theba Hoskens Sectional Title Scheme was registered in November 2007. The first respondent, Blue Dot Properties 271 (Pty) Ltd, was the developer and reserved a real right of extension in terms of s 25 of the Sectional Titles Act 95 of 1986 over a plant area adjacent to section 401. Section 401, comprising most of the second floor, was sold to the appellants. The plant area formed part of the common property and was initially intended to be incorporated into section 401 or made available for its exclusive use. After the appellants declined to purchase the plant area, the developer changed its intention and sold section 302 (below section 401) together with the purported right to extend into the plant area to the seventh respondent. The developer also constructed a brick wall on common property adjacent to section 401. The appellants applied to interdict the transfer or cession of the right of extension to anyone other than the owner of section 401 and sought demolition of the wall. The High Court dismissed the application, treating the matter as a PAJA review and finding that changed circumstances justified deviation from the registered plans. The appellants appealed to the Supreme Court of Appeal.
