It wasn't a mistake. It was the system working exactly as it was meant to work. The only people with their knickers in a twist about it in Australia were the radical leftists who didn't like their totalitarian Prime Minister being sacked for trying to break the law and ignore the constitution. And they were republicans to begin with. Because the left tends to dominate academia, they've managed to spread this idea that the Dismissal in 1975 was some type of grave injustice - it wasn't. It was the Governor General doing what he was supposed to do to deal with a government that was trying to ignore the law, and the Constitution. And the Queen would do exactly the same thing in the UK if needed. The difference is no British Prime Minister is likely to be as stupid as Gough Whitlam was - he managed to convince himself that the Governor General could not act without his permission despite very clear information that he could.
So Whitlam said, “So what are you going to do about it?”
And then found out.
A royal, much like a religious leader, should NEVER have the ability to intervene of interfere with the actual civil government.
Parades and tourism, fine,,, but no unelected person should ever have actual power. The same goes for first ladies, I hate that they always have a “cause” and seem to wield actual power.
In 1975, Gough Whitlam, the Aussie Labor PM, could not get the budget passed in the upper house of Parliament. So he was negotiating a loan from Pakistan to fund the government, which was patently illegal. That’s when the Governor General stepped in and summoned Malcom Fraser to dissolve Parliament. When he was given a vote of no confidence by the Labor Party, which was still in control the lower house, the GG summoned Black Rod to dissolve Parliament. Elections were subsequently held. The most interesting part of the whole episode was the demonstrations in front of Frasr’s party HQ, complete with Soviet flags.
