The four Caribbean firms — Trafalgar Developments, Instantania Holdings, Kamara, and Bairiki Inc — originally sued Mr Mazepin, Eurotoaz, the United Chemical Company Uralchem , a major ammonia producer allegedly controlled by Mr Mazepin, and a number of other companies and individuals based in Russia, Cyprus and Bulgaria.
On Friday, the court heard an application from the original four plaintiff firms to join as co-plaintiffs nine other companies, six registered in the British Virgin Islands, one in Switzerland and two in Cyprus. The plaintiffs say the transfers were done under a trust management agreement whereby the four Caribbean companies became trust managers of the shares.
