Johannesburg Mayor Herman Mashaba would like to meet with the newly appointed NPA head Shamila Batohi once she assumes her office next year.Mashaba is seeking intervention from Batohi to deal with alleged corruption and fraud cases that the City has opened against individuals linked to the municipality.Mashaba said Carte Blanche had aired an exposé on Sunday night about rampant corruption uncovered by the municipality and the baffling decisions of the NPA to withdraw clear-cut, prosecutable cases."On numerous occasions, the City has sought to engage the NPA to raise our concern on the apparent lack of attention paid to fraud and corruption matters referred to it by the City. So far, these engagements have yielded poor results," he said. Mashaba listed a case opened against a former candidate valuer, Mbali McClare, who was arrested for allegedly deliberately undervaluing 22 properties in the city, amounting to just under R500m. The case was withdrawn by the NPA late last month.READ: Mashaba asks Ramaphosa for more powers to fight crime"This is one of a number of slam-dunk cases investigated by the City’s Group Forensic Investigations Services, headed by Shadrack Sibiya, one of country’s top law enforcement officials."Another case which illustrates the NPA's inability to prosecute serious criminality was the withdrawal of the case against the directors of Setheo Engineering," Mashaba said.Two directors from Setheo Engineering were arrested in 2017 after they allegedly colluded with City Power officials and received payments exceeding R66m for work that was never completed in the building of the Eldorado Park sub-station."They had secured the contract, issued under the previous administration, through a fraudulent bank guarantee which led the City to believe that they had the balance sheet to handle the project," he said.Case withdrawnEarlier this year, charges against former member of the mayoral committee (MMC) of housing, Dan Bovu, were withdrawn.Bovu was accused of allegedly selling government land to people within the municipality.According to Mashaba, Bovu’s case was provisionally withdrawn from the roll because material witnesses were no longer prepared to testify, after they were allegedly paid money.READ MORE: Former Joburg housing MMC faces fraud charges for ‘selling land illegally’"Rather than pressing further charges for defeating the ends of justice, corruption and witness interference, the NPA saw fit to provisionally withdraw the case from the roll."It is astounding to the City that justice is not served in the vast number of cases which the City has handed over to law enforcement authorities. This is not only a miscarriage of justice for the City, but also for the law abiding and hardworking residents of Johannesburg," Mashaba said.He added that amaBhungane had uncovered evidence which conclusively showed how former MMC for finance Geoff Makhubo and former mayor Parks Tau had allegedly orchestrated a windfall of at least R30m for Makhubo by allowing him to unduly act as broker for Regiments Fund Managers, giving the fund managers unfettered access to lucrative deals within the City.ALSO READ: Mashaba lauds City of Joburg investigative unit for helping owner get hijacked CBD building back"According to the report by amaBhungane, documents show that Regiments agreed to pay 10% of its fees to Makhubo’s company, Molelwane Consulting, in exchange for Makhubo’s "maintenance of strategic relationships with the COJ [City of Johannesburg]". "This meant that Makhubo, who was tasked with exercising political oversight on one of the City’s largest contracts, was also unlawfully benefiting from the very same contract."Mashaba laid charges of fraud, corruption, money laundering and racketeering against Tau and Makhubo at the Johannesburg Central Police Station on Monday.He said the municipality was currently at an advanced stage of conducting its own forensic investigation into this matter, the evidence of which would be handed over to the investigating officer. "Ultimately, we have every faith the evidence so far collected will be sufficient to secure a conviction. However, given the current withdrawal of numerous of our cases, the City is deeply concerned by the NPA's capacity to effectively prosecute this matter."Every cent lost to corruption means less services for our residents. We cannot allow criminals to continue to go unpunished as they rob our residents. That is why it is essential that all these cases are effectively prosecuted," he continued.Predetermined outcomeThe ANC in Johannesburg said they are not surprised by Mashaba’s actions.Spokesperson Jolidee Matongo said this confirms that there could be a predetermined outcome of the city’s forensic investigation led by Mashaba."It is mind blogging that when amaBhungane released a report on the municipality’s fleet contract two weeks ago, Mashaba cried foul and threatened to go to the Press Ombudsman to take journalists to task."A week later, he was shouting at the top of his voice praising the same amaBhungane for good journalism. In fact, he takes their report to the police as a basis to lay charges. This is hypocrisy at its best," said Matongo.He added that they will wait to see if Mashaba will lay charges against officials who are fingered in the municipal Institutional Review tender debacle and the Field Band Foundation R11m award including himself. The party has challenged Mashaba to act on those two matters among many other irregularities and legalities it says comes from his administration to demonstrate that indeed he is prepared to fight corruption.
