Labor will use its numbers to pass a ‘censure motion’ on Mr Guy, after a vast trove of documents revealed he directed officials to settle a court case with a $2.5 million payout because he was afraid he would lose his job as Planning Minister.

Mr Guy continued to fight back against Labor on Wednesday morning, accusing Premier Daniel Andrews and his senior ministers of being “obsessed” with the Coalition, instead of being focused on governing the state.

With just five parliamentary sitting days left before the state election in November, the government’s motion looks set to dominate proceedings for much of this week’s remaining sessions.

The motion will call on Mr Guy to resign and pay back the ultimate cost of the settlement to taxpayers of $3.5 million, which includes legal costs.

But the motion, if passed, will not oblige the Opposition Leader to do anything, and would simply note for the record the displeasure of the majority of the house with his conduct.

Deputy Premier James Merlino was on the attack again on Wednesday morning, accusing Mr Guy of lying about decisions he made when the government was being sued by the developers involved in the rezoning of land on Phillip Island in 2011.

Mr Merlino shrugged off concerns over the government's decision to break with long-standing convention and release cabinet documents from a previous government.

“It is not the usual practice to release 80,000 documents, but this is in the public interest, this calls into question the judgement and the character of the leader of opposition and potentially criminal behaviour, misconduct in public office,” the Deputy Premier said.

“We’re going to pursue these matters over the next couple of days.”

Manager of government business, Jacinta Allan said, there had only been two censure motions put forward in the lower house in the past two terms of government.

“It does demonstrate the seriousness of this matter,” the Public Transport Minister said.

“But it’s an opportunity for the Leader of the Opposition to answer the questions that he is so desperately trying to duck and avoid answering.”

Ms Allan continued trying to bring other Liberal frontbenchers into the controversy, suggesting Robert Clark and Michael O’Brien, the Attorney-General and Treasurer respectively at the time of the scandal, had questions to answer.

But Mr Guy returned fire on Wednesday morning.

“Labor is spending their time as a government talking about me," Mr Guy said.

“They’re the government. They’re not talking about crime in our city, cost of living pressures, rampant congestion.

“What sort of government is this, that spends its time talking about the Opposition, not about Victorians?”

The government’s censure motion will be debated on Thursday.
