Scott Morrison and his colleagues cannot stop the next cycle of recriminations over the leadership spill that brought their government to a standstill 10 months ago.
The wounds over the leadership spill last August are being reopened with Peter Dutton's assertion that Malcolm Turnbull offered him the deputy leadership at the height of the drama.
But every major event in that convulsion is contested - and this one more than most. Turnbull and Dutton have completely different accounts of their conversation in the hours after the leadership was put to a vote.
The events of the past now create a problem for the present. Morrison does not want to talk about the spill, and would rather bask in the glory of the election outcome, but more scrutiny is certain in the weeks ahead with a Sky News documentary this week, a book by columnist Niki Savva next week and a book by this reporter in the subsequent weeks.
The context is vital in the dispute over what Turnbull offered Dutton or what Dutton asked of Turnbull.
Turnbull shocked almost all his colleagues on Tuesday, August 21 by declaring the leadership vacant and allowing any challenger to stand against him. Nobody had to vote to spill the leadership because Turnbull threw it open.
Dutton and Turnbull spoke at the back of the party room soon after the vote, which the then prime minister won by 48 to 35 votes - a margin too narrow to guarantee his position.
Turnbull asked Dutton to remain Home Affairs Minister but Dutton refused.
"Malcolm came up to me after that party room meeting and said 'I want you to stay on as Home Affairs Minister' and I said: 'No, that position's untenable and I can't accept that'," Dutton told Sky News.
"It's all a pretty high-stakes discussions and a desire to see the best possible outcome. In my mind an easy transition is always the best."
The two men spoke again soon afterwards in the prime minister's office. They have completely different accounts of what occurred.
This was a conversation that decided the fate of the Turnbull government - and therefore led, indirectly, to the birth of the Morrison government.
"He offered me the deputy leader position. I said to him that this was just - given what had just taken place - that that wasn't credible. And it wasn't his to gift, either."
Dutton has given his version of this discussion in a two-part series airing on Sky News on Tuesday and Wednesday night. This matches what he has told this reporter for a book, Venom, to be published by HarperCollins in August.
But this is only one side of the conversation in the prime minister's office that day. Turnbull says there was no such offer. He completely rejects the claim and argues he could not have arranged the deputy leadership for Dutton in any case.
This is crucial because the deputy at the time, Julie Bishop, was one of Turnbull's strongest supporters. For him to offer the deputy leadership to Dutton would have been a devastating act of betrayal.
Turnbull's allies insist it did not happen. Others say he was desperate enough to make the offer. Bishop's enemies had certainly canvassed the idea with Turnbull weeks earlier, so the idea did not come out of the blue.
The record shows there was no deal at this meeting. Dutton resigned, made no arrangement to become deputy and did everything he could to force a second ballot and become leader.
The recollections are now shaped entirely by Morrison's election victory - and the need to lay blame for what took place last year.
There is no shortage of blame for Turnbull in the way he cleared the way for the leadership crisis on that Tuesday by putting his position to a vote.
But there is also an eagerness for everyone else to avoid responsibility, too.
Luke Howarth, an ally of Dutton and now an assistant minister, confirms in the Sky News series that he wanted to stand up at the party room meeting and ask Turnbull to resign. Turnbull knew this was coming. What was he expected to do? Pretend it was just another meeting?
And there were two sides to the vote, just as there were two sides to the disputed conversation about the deputy leadership.
The simple fact is that nobody forced Dutton to stand. Tony Abbott encouraged him, but nobody forced him. The most fateful move that day was the decision by a cabinet minister to challenge the prime minister and trigger an upheaval.
