The deceased, Tebalo Watson Letsela, died intestate in 1993 holding a 99‑year leasehold over immovable property in Vosloorus. He lived on the property with the appellant, Mildred Mthembu, and her two minor daughters, one of whom (Tembi) was his biological child. No valid customary marriage existed between the appellant and the deceased, although part of lobola had been paid. The deceased was also survived by his father (the first respondent), mother and siblings. The magistrate appointed the appellant as administratrix but indicated that the estate devolved according to Black law and custom. The first respondent claimed the property as heir under the customary law rule of primogeniture. The appellant challenged the constitutionality and validity of the customary law rule of succession and regulation 2(e) of the Regulations under the Black Administration Act.
