The respondent, Mr Irvine Sam Mashongwa, was a fare-paying passenger on a PRASA-operated Metrorail train on 1 January 2011. While travelling from Walker Street Station to Mamelodi Gardens Station, he was alone in his coach when four men entered from an adjacent coach. They robbed and assaulted him and then threw him out of the moving train through open doors near Rissik Street Station, causing him injuries. Mashongwa sued PRASA for damages, alleging negligent failure to provide adequate security and to ensure that the coach doors were closed. The High Court separated liability and quantum and held PRASA liable. PRASA appealed to the Supreme Court of Appeal.
