Here’s what the Special Investigating Unit really does, and why it matters now more than ever

In a country where corruption headlines can feel like a daily occurrence, one unit is quietly pushing back. It doesn’t dominate the news cycle. It doesn’t do flashy press conferences. But it’s doing the painstaking work of tracking stolen public funds, investigating dodgy tenders, and holding institutions to account.

Meet the Special Investigating Unit, South Africa’s anti-corruption enforcer with real legal teeth.

What exactly is the SIU?

The SIU was established under the Special Investigating Units and Special Tribunals Act of 1996, and it operates independently from other government bodies. Unlike commissions of inquiry that merely recommend action, the SIU is empowered to investigate, subpoena, seize evidence, and take civil legal action to recover lost public money.

Its investigations begin only after a Presidential Proclamation, and once complete, the final report is submitted directly to the President, regardless of who may be implicated.

SIU vs. the Public Protector: What’s the difference?

Although both bodies deal with maladministration and state misconduct, their powers and approaches differ.

The Public Protector investigates complaints and recommends remedies.
The SIU takes direct legal action in the High Court or Special Tribunal to recover financial losses from corruption and maladministration.

If the Public Protector is a mediator, the SIU is the State’s legal strike force.

What is the SIU currently doing in Gauteng?

Gauteng, being South Africa’s economic engine, is often at the centre of major procurement scandals. In recent years, the SIU has targeted:

PPE contract fraud
Housing project mismanagement
Health department overpricing
Municipal tender irregularities

While active investigations are only made public through the Presidential Proclamation system, Gauteng continues to be one of the SIU’s busiest regions.

Can citizens report past corruption?

Yes. Whether the wrongdoing happened last month or three years ago, the SIU encourages reporting. Allegations can be submitted via:

Phone
Email
Walk-ins
The independently managed whistleblower hotline

Importantly, whistleblowers are protected by law under the Protected Disclosures Act, and their identities are kept confidential.

What powers does the SIU actually have?

Under Section 5(2) of the SIU Act, the unit has the legal authority to:

Subpoena individuals and organisations
Access bank records and phone logs
Search premises and seize documents
Interrogate witnesses under oath

If evidence of criminal conduct emerges, the SIU refers it to the National Prosecuting Authority (NPA) for criminal prosecution.

Who holds the SIU accountable?

The SIU may be powerful, but it’s not unchecked. It is audited by the Auditor-General, reports to Parliament’s Portfolio Committee on Justice, and appears before SCOPA. Internally, it has its own Integrity Unit, audit committees, and risk management systems.

Why does it take so long to investigate?

The SIU’s work isn’t quick, but that’s by design. Investigations can span months or years depending on:

Volume of documents and data
Complexity of the fraud
Availability of witnesses
Legal scope outlined in the proclamation
Budget and resource constraints

South Africans often expect quick results, but in cases involving billions of rands, thoroughness is key.

Beyond reports, they actually recover money

Perhaps the most critical difference between the SIU and other oversight bodies is that the SIU doesn’t stop at findings. It actively recovers state funds, freezes assets, and cancels illegal contracts.

They don’t just expose corruption. They reverse it.

Why the SIU matters now

In 2025, South Africans are still living with the impact of past corruption, from broken hospitals to pothole-riddled roads and water shortages. Every stolen cent matters. And while the SIU may not always trend on social media, its work is among the most important in restoring accountability and trust in government.

In a sea of broken promises, the SIU is one of the few state entities still delivering results.
