Because laws can be repealed ? The purpose was to make it binding so there was always a indigenous body, unlike all of the previous bodies that cease to exist with change in government. Granted none were legislated I don't believe

Your suggestion has been tried repeatedly and the moment the right-wing have the power needed to tear it down, that's what they do.

The answer to that lies within the question: why put anything in a constitution? Why have a constitution?

Anything could be made using laws or rules. And anyone can then undo and rewrite them.

It's because countries generally need a foundational document outlining how government will operate, and how laws will be made, and what the country stands for. And have the stability and security of knowing that those operating principles can't be easily changed.

So the idea was, by incorporating the Voice within the constitution, you recognise indigenous Australians in your foundational document as having the right to have a recognised voice on what concerns them, and having unique aspects of history, and historical treatment, that make that appropriate.

Not a right to dismiss laws, or change them. Not a right to create laws. Not a right to ignore laws, or amend proposals. Just to have a recognised voice on issues affecting them, and ask the "lawmakers" to do any of the above.

This is important, because yes, you don't want to enshrine anything that gives a small proportion of the population the ability to sidestep the legislative and political process.

But as a country, we do want to enshrine a means by which indigenous Australians, - a historically extremely disadvantaged group of people, who form less than 4% of the population, and don't have the financial or organisational means to engage expensive political lobby firms like large corporations and mining companies- can participate more directly with the political process of laws affecting them, and therefore feel symbolically "seen".

An analogy: If a public company wanted to create a Disability and Equity officer position, and wanted that position enshrined in the company charter to show the public that: the company was really serious about that position; provide good PR; signal to the public the company's values; and protect it from being included in future job cuts, or made redundant in future for economic or ideological reasons under a different CEO, they would present shareholders with the question and put it to a vote.

The company would not include within that question, details about how much that position would be paid. Or what room of what building they would work in. Or how they would communicate. Or what restrictions would be put on the position. Or how candidates would be interviewed, assessed, and hired.

Shareholders would just see something like: "The company resolves to include the position of Disability and Equity Officer in the company charter, as an indication of the company's desire that it become a more inclusive workplace, and to signal those values to the general public."

Because while you want people to know the position is permanent, you also want to leave the nitty gritty details to being guided by other processes, so that they can be changed more flexibly then once a year or more at a General Meeting of all shareholders

Solicit feedback, definitely - but soliciting that feedback in the moment that people are voting on the constitutional amendment that would implement that feedback is a little late, no?
