The respondent (P3 Management Consultants, a South African company and incola of the Witwatersrand court) sued the appellant (Hay Management Consultants Ltd, an English company and peregrinus of South Africa) for repayment of R515,815 paid under protest. The parties had concluded a written agreement in London in November 1989 whereby the appellant granted the respondent a licence to operate a management consultancy in Southern African countries including South Africa. The agreement contained: (i) a choice of law clause (clause 15) selecting South African law as the proper law; and (ii) a domicilium clause (clause 16.1) requiring the English company to choose a domicilium citandi et executandi in South Africa (Johannesburg) for service of legal process. The respondent claimed repayment of amounts paid as royalties, alleging they were not due under the agreement. The appellant raised a special plea to jurisdiction, arguing it was a peregrinus, had not consented to jurisdiction, and no property had been attached. The jurisdictional issue was tried separately on the pleadings without evidence.
