Parliamentary sovereignty gives parliament the right to enact whatever law it chooses. There are no limits other than the ones it imposes on itself.
Beyond that, I’m not entering into a debate on the merits of what it should do. I only wanted to point out what it can do legally, to which the answer is ‘anything.’ And yes, that includes going rogue and ignoring international commitments. I’m a long way beyond wasting my time arguing with people who think it’s a good thing to be willing to walk away from international agreements. I’m simply pointing out that the provisions of the WA, despite what was said at the time, do not impose legal restraints on what Parliament now chooses to do.
On the last paragraph, Perhaps we can agree that they are a bunch of incompetent cunts?
