(2) Subject to this Code and any other enactment, mistake or ignorance of an essential fact may be a defence to a crime referred to in subsection (1) even if it is not reasonable:
Provided that the reasonableness or unreasonableness of any mistake or ignorance may be taken into account in determining whether or not it is genuine.

(b) when he or she did or omitted to do the thing, he or she did not know that his or her conduct was
unlawful because he or she was genuinely mistaken or ignorant as to the relevant provisions of the law; the person shall not have a complete defence to a charge of committing that crime unless the person’s mistake or ignorance as to the relevant provisions of the law was directly brought about by advice given to him or her by an administrative officer whom he or she had reason to believe was charged with the administration of the law
concerned and was familiar with its contents.
[Subsection amended by section 31 of Act 9 of 2006.]

If in any criminal case a person charged with any crime against property raises a defence of claim of right, namely that the person believed he or she had a right to do or omit to do any thing, the court shall determine whether or not the belief arose from mistake or ignorance of fact or law and, if the court decides that the belief arose
(a) solely from mistake or ignorance of law, the court shall regard the defence as one of mistake or ignorance of law in terms of this Part; or
(b) solely from mistake or ignorance of fact, the court shall regard the defence as one of mistake or ignorance of fact in terms of Part VII; or
(c) partly from mistake or ignorance of law and partly from mistake or ignorance of fact, the court shall regard the defence as one of mistake or ignorance of law in terms of this Part.
