The respondent instituted an actio rei vindicatio in the Johannesburg High Court for delivery of certain movable equipment (compressors, compressed air pipes and related equipment) used in a furniture manufacturing business. The equipment had belonged to A F Dreyer (Pty) Ltd, which went into liquidation in February 2002. The respondent claimed ownership through a post-liquidation auction held on 19 March 2002, at which it purchased the company’s movable assets. The appellants, trustees of two trusts owning the premises where the business operated, were in possession of the equipment and denied the respondent’s ownership. The written conditions of sale limited the assets sold to those listed in Annexure A and certain handwritten inclusions; the equipment in dispute was not listed. The respondent relied on an alleged prior oral agreement that all movables within an enclosed area of the premises, except specified exclusions, were included in the sale. The appellants disputed the existence and legal effect of this oral agreement.
