The deceased, Mr Pieralberto Za, slipped on a snow-covered slope at Conical Peak in the Matroosberg private nature reserve and fell over a 150-metre precipice to his death. The reserve was owned by the first respondent, with the second respondent operating it as a commercial nature reserve open to paying members of the public. The appellant, his widow, sued in her personal capacity and on behalf of their three minor children for loss of support, alleging that the respondents wrongfully and negligently failed to take reasonable steps to warn visitors or protect them from the hidden danger posed by icy conditions near the precipice. The High Court dismissed the claim on the basis that causation was not established.
