Hall & Sons, the owner of a commercial property leased to Shell, granted Shell a contractual right of pre-emption in clause 21 of a long-term lease. In October 2014 Hall & Sons received an offer from Tiekiedraai to purchase the property for R17 million, subject to several conditions and with further terms to be agreed. Hall & Sons forwarded this offer to Shell, asserting that Shell’s pre-emptive right was thereby triggered. Shell maintained that the offer did not contain all identical terms and conditions as required by the lease and therefore did not trigger the 30‑day acceptance period. Only in December 2014, once Hall & Sons concluded and forwarded a full written sale agreement with Tiekiedraai, did Shell accept the offer on identical terms. The High Court held that Shell had validly exercised its right of pre-emption and that the sale to Tiekiedraai was invalid. Tiekiedraai appealed to the Supreme Court of Appeal.
