ANC heavyweight and KwaZulu-Natal deputy chairperson Mike Mabuyakhulu's ability to hold office is being hindered because of slow progress in his corruption matter, his lawyer said on Friday."My client has a right to a reasonably fair process. Despite efforts from our side, this is not happening. We believe we are being prejudiced. The delays are compromising my client's ability to hold public office," Jimmy Howse told the Commercial Crimes Court.Mabuyakhulu and his seven co-accused appeared in court on Friday.He faces charges of money laundering and corruption, relating to R28m allegedly paid for a North Sea Jazz Festival in Durban in 2012, which never took place.READ: Top ANC leader from KZN and co-accused back in court over North Sea Jazz FestivalHowse expressed dissatisfaction after it was revealed that a new indictment had been served on the accused, with "significant" differences to the original one."We were only provided with this on January 28. Besides us, none of the other accused have seen this new indictment. If we had not approached the State, we would not have received it either. This is worrying because it causes delays."He said there had been significant changes, including two completely new charges and changes to dates."We are in a prejudicial position because we had requested particulars from the old indictment. Those requests are not in conjunction with the new indictment."He also questioned how new charges emerged when investigations commenced in 2012 already."It has been years and we feel this is an unreasonable delay. I will have to look at the new documents and see if we will proceed with an application for the unreasonable delay."ALSO READ: ANC KZN deputy chair only played a 'peripheral role' in R28m case - new lawyerMabuyakhulu was arrested in 2018 along with seven others.
