Can I make an addendum, then?
If it turns out that there is a legal obligation that stems from even elements of it—maybe some of it not, but other elements yes—then I don't know how it can not be legislative. Let's say there's a consensus on the document here--which there will be, presumably, at some point--and the minister makes a declaration of a bill of rights, say. That would be sufficient to deal with the legal aspects.
So there are some good questions, I think, for legal counsel when that person comes.
