78 Finally, I should note that in oral submissions, counsel for Mr and Mrs Kitching placed considerable reliance on the decision of the High Court in Shepperd v The Council of the Municipality of Ryde [1952] HCA 9; (1952) 85 CLR 1. In that case, the Municipality of Ryde had created a subdivision on which it was constructing 2,500 homes. The council advised potential purchasers, by pamphlet, that the scheme included a complete range of services, including park areas. The plaintiff applied for a house in the scheme and received an offer from the council to acquire a home which was opposite two park areas. The plaintiff discussed the importance of the park areas with a council officer, and the council officer pointed to two pieces of land on the plan, and confirmed that they would both be park areas. A few days later, the plaintiff advised the council that he would purchase the house, and again he mentioned the importance of the park areas. A contract for sale was then executed. The contract referred to the land the subject of the contract for sale as being 'part of the Vendor's Housing Project ... and being Allotment No ... '. About a year after the plaintiff acquired the house, the council resolved that the two park areas should be subdivided and houses built on those allotments. The plaintiff applied for an interlocutory injunction to restrain the proposed alienation of the two park areas. The plaintiff failed in the Supreme Court, but succeeded in the High Court. The High Court held, in effect, that there was arguably a collateral contract, as well as an implied term of the sale contract, to the effect that the council would not depart from the housing scheme, and would not use or permit the two areas in dispute to be used for any purpose other than a park.
