The legal battle between KZN Police Chief Mkhwanazi and forensic investigator Paul O’Sullivan is capturing national attention. In September 2025, Mkhwanazi filed a R5 million defamation lawsuit in the Johannesburg High Court. This follows months of public disputes, sharp accusations, and the launch of a judicial commission of inquiry into policing in South Africa.
The R5 Million Defamation Lawsuit
In mid-September, KZN Police Chief Mkhwanazi Sues Paul O’Sullivan after alleging that O’Sullivan repeatedly damaged his reputation in public. According to court papers, three separate statements made by O’Sullivan earlier in 2025 form the basis of the claim.
The summons states that O’Sullivan accused Mkhwanazi of:
- Misusing police funds during his tenure as acting national commissioner.
- Accepting undisclosed luxury gifts from associates.
- Having links to organised crime networks.
Mkhwanazi argues these claims are false, harmful, and have eroded public trust in his leadership. He is demanding R5 million in damages and an apology.

O’Sullivan’s Position on the Claims
Paul O’Sullivan is one of South Africa’s most outspoken forensic investigators. In response to the lawsuit, he confirmed receiving the summons but declined detailed comment, citing sub judice restrictions.
However, Paul O’Sullivan noted that he intends to present evidence before the Madlanga Commission of Inquiry, a judicial panel probing allegations of corruption and political interference in policing. He stressed:
“Lt General Mkhwanazi has issued a defamation summons against me … Curiously, in his summons he does NOT make any denials whatsoever, but only demands R5 million.”
This remark underscores O’Sullivan’s strategy of shifting the fight from media statements into formal legal and commission settings.
The Broader Context: Political Interference in Policing
The defamation case does not exist in isolation. In July 2025, President Cyril Ramaphosa announced a judicial commission of inquiry, led by Acting Deputy Chief Justice Mbuyiseli Madlanga. The inquiry was triggered by Mkhwanazi’s allegations that senior political leaders interfered in police operations.
Following these explosive claims, Police Minister Senzo Mchunu was placed on leave of absence. The commission is expected to hear testimony from both Mkhwanazi and Paul O’Sullivan in coming months.
July Statements Now in Court Spotlight
Part of the lawsuit stems from O’Sullivan’s public remarks in July, shortly after Mkhwanazi’s press conference. At the time, O’Sullivan said Mkhwanazi may have “ended his life in the police” and called his conduct “dangerously suspicious.” He demanded that the commissioner be suspended pending investigation.
These statements, made on air and reported widely, now form key evidence in Mkhwanazi’s defamation claim.

Legal and Public Repercussions
This case highlights the fragile balance between accountability, free speech, and reputational harm in South Africa’s public sector. For Mkhwanazi, the lawsuit represents a bid to defend his integrity. For O’Sullivan, it is a test of whether his outspoken style is protected under the law.
The outcome may influence public trust in the South African Police Service (SAPS) and could shape how whistle-blowers and investigators operate in future.

The clash between KZN Police Chief Mkhwanazi and Paul O’Sullivan is far more than a personal dispute. It sits at the crossroads of politics, policing, and public accountability.
As the Johannesburg High Court hears arguments and the Madlanga Commission prepares for testimony, South Africans are watching closely. The verdict and findings will likely echo far beyond the courtroom, influencing trust in law enforcement and the credibility of those who claim to expose corruption.
