Had an interesting morning coffee with a mate who is a Barrister. His take is that the voice is fine but the unknown back up legislation 'could' be an issue whereby that legislation turns an advisory body into an authority. I countered that legislation is not enshrined in the constitution and subject to change and that the days of uncontrolled majorities are a thing of the past. He also mentioned the full Uluru document, which I have only scanned, saying the one pager hides the real intent. Interesting take. I will properly read the whole document.
