Why doesn't the Constitution mention the Prime Minister or Cabinet?

This video discusses why the Commonwealth Constitution does not mention the Prime Minister or Cabinet. It explains the history of the term 'Prime Minister' and how it was used interchangeably with other terms, such as Premier, First Minister and Chief Minister. It notes the formal title 'First Lord of the Treasury' in the United Kingdom, but that this title was not used in Australia. The video outlines the provisions of the Commonwealth Constitution which concern the appointment of 'Ministers' (including the Prime Minister, who is a Minister) to 'offices' and to administer Departments. It mentions the Morrison secret ministry controversy, and the fact that Prime Ministers actually have quite limited legal powers (despite the fact that most people seem to think that they 'run the country'). The video explains that the Cabinet has no legal powers, and that effect is given to Cabinet decisions through the powers conferred on others, including Ministers and the Federal Executive Council. (Note that I have also done another video on the difference between the Cabinet and the Federal Executive Council:    • Cabinet v Executive Council - What's the d...  .) The video concludes by discussing why the framers of the Constitution were not more prescriptive in setting out in the Constitution how the executive government operates.
