Following an unlawful and violent demonstration by members of the South African National Defence Force (SANDF) at the Union Buildings on 26 August 2009, the SANDF made several attempts to discipline participating soldiers. Earlier disciplinary processes were set aside as unlawful. In 2012 the SANDF issued notices and newspaper advertisements to soldiers who had not returned to their units, indicating an intention to administratively discharge or dismiss them under s 59(2)(e) of the Defence Act 42 of 2002 on the basis that their continued employment posed a security risk to the State. The South African National Defence Union (SANDU) challenged this third attempt, arguing that the absence of regulations under s 59(2), and the procedure followed, rendered the process unlawful and unconstitutional.
