At the heart of the quandary in protecting rights under an Australian Bill of Rights is the ultimate loss of a democratic voice, with government being subject to an un-elected judiciary.
The very process of public discussion and opportunity for submissions to the Human Rights Commission is an example of democratic process but we should not be under the illusion that such contributions will change what the consultation committee decide and recommend. It is likely that the recommendation will proceed along the lines of the agendas proposed by the rights faction.
Why has the government as a result of the 2020 Summit chosen to look at statutory legislation as the avenue of introduction instead of a constitutional change? Precisely because it has been twice before rejected by referendum.
