On 6 July 2004, the respondent (Kingdom Merchant Bank) issued summons against the appellant (Jayesh Shah) and Saturn Trading and Investments Limited jointly and severally for payment of US$900,000. The respondent alleged this amount represented overpayment of a loan advanced to Saturn Trading for onward lending to third parties. The respondent claimed Saturn Trading had been unjustly enriched by the overpayment. The respondent also sued the appellant personally on grounds that as director, agent or alter ego of Saturn Trading, he was fully aware of the transactions and had a duty of care towards the respondent. The respondent alleged the appellant carried out Saturn Trading's business negligently, recklessly, fraudulently and without due care. At a pre-trial conference on 26 September 2006, the respondent obtained leave to amend its declaration with the appellant's consent. On 30 November 2007, the respondent's legal practitioners requested consent for further amendments, which the appellant refused. The respondent then filed an application for leave to amend its declaration in terms of Order 20 r 132 of the High Court Rules. The High Court granted leave to amend on 22 May 2013. The appellant appealed this decision, arguing the amendment introduced new causes of action (unjust enrichment, fraudulent misrepresentation, and theft) that had prescribed.
