The respondents, thirteen individuals involved in the diamond industry, were prosecuted on 139 counts including contraventions of the Diamonds Act and racketeering under POCA, arising from a covert police investigation (‘Project Darling’) conducted between 2012 and 2014 using undercover agents and s 252A CPA authorisations. Arrests occurred in August 2014. The prosecution was marked by extensive pre‑trial litigation, disclosure disputes, postponements, witness illnesses, and interlocutory applications. After the trial commenced in the High Court in August 2016, a second recusal application succeeded in July 2018 when it emerged that the trial judge had earlier been the subject of an attempted bribe and intimidation linked to the case. The recusal rendered the proceedings a nullity, requiring any further prosecution to commence de novo. The respondents applied for a permanent stay of prosecution on the basis that the delays—allegedly attributable to the State and the recusal—violated their constitutional right to a trial within a reasonable time under s 35(3)(d) of the Constitution. The High Court granted a permanent stay. The DPP appealed to the Supreme Court of Appeal.
