The applicants, including Gaston Savoi, Intaka Holdings (Pty) Ltd, and Fernando Praderi, were charged in the KwaZulu-Natal High Court and the Northern Cape High Court with offences including racketeering, fraud, corruption, and money laundering arising from alleged unlawful conduct connected to public tenders for water purification plants, gas generation systems, and dialysis machines. Before the criminal trials proceeded, the applicants launched a constitutional challenge against provisions of the Prevention of Organised Crime Act 121 of 1998 (POCA). They argued that the statutory definitions of “pattern of racketeering activity” and “enterprise”, section 2 of POCA, and Chapter 2 as a whole were unconstitutional on grounds of vagueness, overbreadth, retrospectivity, and infringement of fair trial rights under section 35 of the Constitution. The High Court rejected most of the challenge but declared parts of section 2(1) invalid insofar as they included the words “ought reasonably to have known”. The matter came before the Constitutional Court for confirmation of that declaration and on appeal and cross-appeal.
