Framatome (as contractor) and Eskom (as employer) entered into a NEC3 Engineering and Construction Contract on 5 September 2014 for the replacement of steam generators at Koeberg Nuclear Power Station. The contract was based on standard NEC3 ECC conditions and provided for dispute resolution through adjudication. Disputes arose regarding compensation events - specifically relating to changes to key dates 2, 14 and 24. On 11 December 2018, Framatome referred Dispute 7 to adjudication. The adjudicator issued Decision 7 on 26 February 2019, finding that the Project Manager's instruction of 29 May 2017 was a compensation event. Eskom did not give notice of dissatisfaction. Following Decision 7, the Project Manager failed to assess the compensation event despite Framatome's notification under clause 64.4. Framatome referred a further dispute (Dispute 11) to the adjudicator on 23 April 2019. In Decision 11 (23 July 2019), the adjudicator found that Eskom had failed to make a full assessment in due time and that Framatome's quotation was deemed accepted. Eskom notified dissatisfaction with Decision 11 and refused to give full effect to it. Framatome instituted enforcement proceedings in the High Court, which dismissed Framatome's application. Framatome appealed to the Supreme Court of Appeal with leave of that Court.
