On 4 August 2026, during a meeting of the Parliamentary Portfolio Committee on Forestry, Fisheries and the Environment, the National Prosecuting Authority (NPA) issued fresh warrants against Sasol, seizing electronic and documentary evidence at the company’s Secunda facility. The warrants were executed while Sasol executives were before the committee, and mark the latest development in a criminal investigation that has been running, with significant delay, since a whistleblower’s complaint in 2019.

The Department of Forestry, Fisheries and the Environment (DFFE) intends to bring the matter back before court in September 2026, having provisionally withdrawn charges in July 2025 to evaluate sixteen new witness statements. The DFFE has also confirmed that it will formally review Sasol’s Waste Management Licences under   (NEMWA), with the possibility of amendment, suspension or revocation once the criminal proceedings are concluded.

Background: From Whistleblower Complaint To Criminal Prosecution

The matter originates in a 2019 protected disclosure by a former Sasol process controller, who alleged that a broken chemical sewer valve at Sasol’s Secunda Benfield plant had caused the unlawful discharge of hazardous chemical waste, including vanadium, diethanolamine and potassium carbonate, into the Klipspruit River, which flows into the Vaal River system.

The DFFE’s criminal investigation began in May 2019, but the docket was only handed to the NPA in December 2021. Sasol was formally summoned to court in July 2022, facing a six-count indictment. As the trial was due to begin in July 2025, the state provisionally withdrew all charges to evaluate newly submitted witness evidence, with the matter since elevated to the Mbombela High Court.

A parallel investigation by the South African Human Rights Commission (SAHRC), also opened in 2019, stalled for years before the case file was closed in August 2023 without seasonal testing being conducted, despite a recommendation from its own appointed consultant that such testing was necessary. The Public Protector is now investigating the SAHRC itself for systemic delays and for allegedly exposing the whistleblower’s identity during its proceedings.

Key Legal Issues

Criminal Liability Under Nema And Nemwa

The six-count indictment against Sasol concerns alleged unlawful discharge of hazardous waste in contravention of environmental legislation. Separately, and irrespective of the outcome of the criminal proceedings, the DFFE has indicated that it will exercise its statutory review powers under section 53 of NEMWA in respect of Sasol’s existing Waste Management Licences. This is a significant development: it confirms that administrative licence consequences may follow independently of, and are not contingent upon, a criminal conviction.

Digital Evidence And The Cybercrimes Act

The fresh warrants were issued under both the Criminal Procedure Act 51 of 1977 and the Cybercrimes Act 19 of 2020, and were used to seize electronic and documentary evidence relating to Benfield Phases 3 and 4, as well as to investigate whether Sasol officials provided false or misleading information to inspectors. The use of cybercrime-related search and seizure powers in an environmental prosecution illustrates a broadening of the investigative toolkit available to regulators, extending beyond traditional site inspections and water sampling into digital forensics.

Whistleblower Protection And Retaliation Risk

A discrete count of the indictment concerns the alleged victimisation, harassment and unlawful treatment of the whistleblower for making a protected disclosure. The whistleblower was admitted to the national Witness Protection Programme in April 2024. Sasol disputes any causal link and maintains that the whistleblower’s departure was voluntary and mutually agreed. Regardless of the ultimate finding, the case demonstrates that Protected Disclosures Act exposure can run as a parallel and independent line of liability alongside the underlying environmental allegations, with attendant reputational consequences.

Institutional Fragmentation And Delay

The seven-year history of this matter, spanning the DFFE, the SAHRC, the Public Protector and now the NPA, illustrates the practical consequences of fragmented regulatory oversight. The DFFE itself has acknowledged to Parliament that the effectiveness of environmental law is hindered by lengthy criminal court proceedings and fragmented oversight across provincial and local authorities. This is a structural weakness that recurs across the environmental and water compliance landscape, and one we have previously flagged in relation to the institutional coordination risk raised by the Water Services Amendment Bill.

Potential Impacts On Mining Industries

Companies operating in the petrochemical, mining, and broader heavy industrial sectors should note the following implications arising from this case –

• Licence review independent of prosecution – holders of waste management licences under NEMWA, and water use licences under the National Water Act, should anticipate that regulators may initiate licence review, amendment, suspension or revocation proceedings independently of, and without waiting for, the conclusion of any parallel criminal case;
• Expanded investigative powers – the use of Cybercrimes Act search and seizure powers signals that environmental regulators and the NPA are prepared to use digital forensic tools to test the accuracy of information provided to inspectors, increasing the risk associated with internal reporting and record-keeping practices;
• Whistleblower and retaliation exposure – companies should expect Protected Disclosures Act claims to be pursued as a distinct head of liability alongside environmental charges, with associated reputational and Witness Protection Programme implications where retaliation is alleged;
• Live parliamentary scrutiny – oversight by parliamentary portfolio committees is emerging as a real-time reputational and regulatory pressure point that operates in parallel with, and sometimes ahead of, formal enforcement action;
• Evidentiary record-keeping – the DFFE’s reliance on historical sampling data, internal system reports and technical audit records, in the absence of contemporaneous samples, underscores the importance of robust, defensible environmental monitoring and record retention practices, which may ultimately determine the outcome of similar disputes.

Observations

The Sasol matter illustrates that South Africa’s environmental legislative framework, comprising NEMA, NEMWA and the National Water Act, already contains extensive criminal, administrative and licensing enforcement mechanisms. The difficulty, as this case demonstrates, lies less in the adequacy of the law itself and more in the coordination, capacity and speed of its enforcement across multiple departments and Chapter Nine institutions. Companies should not treat regulatory delay as a diminished risk; as this case shows, dormant investigations can, and do, resurface with materially expanded evidentiary and enforcement scope.

How Bishop Fraser Attorneys Can Assist

The Sasol investigation signals a more assertive and technically sophisticated approach to environmental criminal enforcement in South Africa, extending to licence review, digital evidence gathering and whistleblower-related liability.

Bishop Fraser Attorneys advises clients on environmental compliance audits, waste management and water use licensing, protected disclosures policies and whistleblower risk management, and engagement with regulators and parliamentary oversight processes. Proactive review of licensing and reporting practices may materially reduce exposure as enforcement in this sector continues to intensify.
