 Because the House of Assembly was much larger than the Senate, the system was designed to protect the stronger position of the House in any joint sitting.A similar method of resolving disagreements exists in the Australian Parliament and the Indian Parliament, but the Australian Senate and the Rajya Sabha are each half the size of the Australian House of Representatives and the Lok Sabha, respectively, whereas the South African Senate was only one-third the size of the South African House of Assembly.Unlike the Australian model (but like the Indian one), no double dissolution election occurred before a joint sitting, further strengthening the position of the House of Assembly and the Prime Minister over the Senate.
