Section 21 (1)(a)(i) of the Drugs and Drug Trafficking Act 140 of 1992 is declared constitutionally invalid:
- If in the prosecution of any person for an offence referred to -
(a) in section 13(f) it is proved that the accused -
(i) was found in possession of dagga exceeding 115 grams;...
it shall be presumed, until the contrary is proved, that the accused dealt in such dagga or substance;
The argument was that this section placed the burden of proof on the accused, which is contrary to Section 25(3) of the Constitution:
- Every accused person shall have the right to a fair trial, which shall include the right - ...
(c) to be presumed innocent and to remain silent during plea proceedings or trial and not to testify during a trial;
Presumption of dealing based solely on an amount possessed no longer applies in criminal proceedings in South Africa.
