Australia's Best Post WWII Prime Minister

[Citizen Hats]

Kerr did what he was supposed to do. the Prime Minister couldn't pass a budget, and refused to do anything to remedy that situation, so he was dismissed, and that action was ratified by the public in the subsequent election.

Jean did something within the range of acceptable actions- that is following the advice of the Prime Minister, though she was constrained by the threat that the Tories were going to launch a full-boar media attack on her had she ruled differently. Instead, she gave Harper his prorogation, and ordered him to deliver a budget which could survive in the House of Commons, which he did. I might have preferred that she refuse him his prorogation until he had demonstrated the confidence of the house, but considering how rapidly the coalition fell apart, and how unpopular a government resting on the support of the separatists was, I can't say that she made the wrong  decision

As for Lord Byng, in 1925, he was faced with the situation where there had just been an election, and given the fluidity of the Progressive Party, it appeared that there was a plausible Tory Government supported by Progressives. This proved not to be the case, but hindsight is hindsight
