Transnet Limited, as owner of immovable property known as the Pinetown PX, instituted an action based on the rei vindicatio in the KwaZulu-Natal High Court seeking eviction of Newlyn Investments (Pty) Ltd. Newlyn admitted Transnet’s ownership but alleged a contractual right of continued occupation. It relied on a written addendum to an existing lease, granting renewal rights, and an oral agreement for occupation of the remaining portion of the property. The original written lease expired on 31 December 2005 and contained a non-variation clause. The alleged addendum, which extended the lease for long periods, could not be produced and a document initially annexed was later shown to be a forgery. Newlyn contended that a genuine addendum existed but was in Transnet’s possession. It sought to prove the addendum’s existence and terms through contemporaneous documents and oral evidence from witnesses involved in the negotiations and execution. The High Court accepted this evidence and dismissed Transnet’s eviction claim. Transnet appealed to the Supreme Court of Appeal.
