Block and Trifecta Director Christo Scholtz were convicted for corruption and money laundering in 2016 by the Kimberley High Court.
The two were found guilty in the case relating to multimillion-rand property tenders awarded by the Northern Cape government departments – over a two year period starting in 2006.
The money laundering charge was however dismissed by the Supreme Court of Appeal.
The two lost their leave to appeal their sentence at the constitutional court last week.
