In discussing the difference between passing and promulgation, it is established that a statute typically requires publication in the Gazette for promulgation. However, Du Plessis identifies two exceptions:
- A statute may have specific requirements for additional forms of publication alongside Gazette publication, such as displaying a notice in a public area.
- In rare cases, the requirement for Gazette publication can be waived under section 16A of the Interpretation Act if the State President believes that delays in publication are due to circumstances beyond the government's control. In such cases, alternative modes of publication can be proclaimed.
