The Johannesburg law firm Norton Rose Fulbright, representing three of Mandela's long-time friends and directors of two investment companies he organized, said the case has been delayed.
Daughters Makaziwe and Zenani Mandela are attempting to gain control of the companies, Harmonieux Investment Holdings and Magnifique Investment Holdings, worth 1.7 South African dollars, the BBC reported Monday.
The three -- human rights lawyer George Bizos, former Housing minister Tokyo Sexwale and lawyer Bally Chuene, were never formally appointed to serve on the companies' boards and have rejected requests to resign, the sisters claim.
Mandela's grandson Mandla has publicly accused the sisters of attempting to engage in a "blatant abuse of the elderly" and "loot" the wealth of the ex-president, now 95 and in ill health, the BBC said.
