The council sold 6.71 acres of land, which had been used for nearly 20 years as a school playing field to the plaintiffs, a firm of builders, who intended to develop an housing estate. The sale was completed in March 1989. By October 1989 they had still not obtained planning permission for the development and the value of the land had fallen due to the general decline in market prices. The contract price in 1988 was £5,082,000. The value in 1990 was less than half that figure. The builders had borrowed the whole of the amount which they had paid and interest rates were high. In October 1990 a sewage pipe was discovered crossing the land diagonally about two metres below the surface. Because the land had been used as a playing field, the manhole, which would have revealed its existence had been covered and grassed over. The pipe carried foul sewage as opposed to surface water drainage from a neighbouring block of flats owned by the council. It discharged into a public sewer outside the boundary on the far corner of the site. It also served a building which had been constructed on that part of the site, but which would be demolished to make room for the housing development planned. Neither the builders nor the council at the time of sale knew of the existence of the sewer. The builders sought to set aside the contract and recover the sum of £5,082,000 which they had paid in 1989 on the grounds of misrepresentation and mistake. The High Court held that they were entitled to do so. The council appealed.
Held The appeal was allowed.
