Advocate Andrea Johnson invokes s35(3)(j) self-incrimination protection

Legal commentary
On Day 144, Advocate Andrea Johnson — Director of the Investigating Directorate Against Corruption (IDAC), which is prosecuting the Crime Intelligence matter this Commission has also examined — placed on record that she will invoke the privilege against self-incrimination under section 35(3)(j) of the Constitution if called to testify on certain matters, stating in her affidavit that "the Commission's fact-finding mandate does not override [her] constitutional protection against self-incrimination under any circumstances." The position sits on genuinely unsettled ground. Section 35(3)(j) by its terms protects an accused person in a criminal trial; a commission of inquiry, by contrast, ordinarily may compel a witness to answer, the historical accommodation being not a right of refusal but a measure of use immunity — the witness must answer, but the answers may not be used directly against them in a later prosecution. That framing exposes the two questions the record does not resolve. First, whether a witness in Adv Johnson's position may decline to answer at all, or must testify subject to immunity. Second — and more consequential — whether any protection would bar only the direct use of her testimony or its derivative use as well, since investigative leads derived from compelled evidence are precisely where the practical protection is thinnest. South African commissions have repeatedly had to grapple with versions of this tension; how the Madlanga Commission resolves it, on these facts, has not been settled.
In plain terms
The person leading the investigation into corrupt police officials has told the Commission she may refuse to answer certain questions about her own conduct — using the same constitutional right that lets any South African stay silent rather than incriminate themselves. That right is real and it belongs to everyone. But it raises an uncomfortable question here: can the head of a corruption investigation decline to explain her own actions, at the very inquiry set up to get to the bottom of that corruption? There is a twist most coverage misses — at a commission you usually cannot simply refuse; the deal is that you must answer, but what you say cannot later be used to convict you. Whether Adv Johnson can go further and stay silent, and whether the protection also covers the leads investigators might build from her answers, is exactly what the Commission has not yet decided. None of this is evidence she did anything wrong — everyone has this right — but it does mean the public may not get a full account of her role from her own mouth.
