Just months before the November state election, in a highly unconventional tactic, the Andrews Government has used Parliament to table documents from the previous Coalition government to attack Mr Guy, now the Opposition Leader.

Documents from previous governments are usually considered off limits.

In 2011, Mr Guy rezoned land on Phillip Island, at Ventnor, only to backflip a month later after public outcry, with the land owners suing the minister and the state over the backflip.

Among those protesting the rezoning, which was linked to some Liberal Party members, was teen star Miley Cyrus who famously tweeted her disgust at the development proposals.

Among the 80,000 pages of documents tabled in state Parliament on Monday, are details of a settlement struck on the eve of a court case that could have seen ministers and the former premier Ted Baillieu cross examined.

Documents show that the government in 2013 settled for $2.5 million to plaintiff Carley Nicholls who was buying the land to develop.

The settlement also included a deal between Ms Nicholls and the property vendors.

The $2.5 million settlement does not include legal costs which are understood to be at least $750,000 for the government.

Labor 'throwing mud'

Labor's decision to use Parliament to access documents from a former government is seen as dangerous precedent in some circles, and gives an insight into how the state election campaign may be fought.

Deputy Premier James Merlino, who has not read the documents, told reporters the public had a right to know about Mr Guy's behaviour in government and the "dodgy deal".

"Victorians have a right to know about what went on with the Ventnor scandal," he said.

On Monday morning, Mr Guy said he was focused on preventing crime in Victoria, adding that he was not worried about what the documents may reveal.

"The Labor Government is focused on throwing mud on political opponents. How does that solve our crime rate? How does that make people's life easier?" Mr Guy said.

The Opposition have attacked Labor over the last year over the so-called rorts for votes scandal, after the ombudsman found Labor had misused $388,000 of taxpayer funds to campaign for votes in 2014.

Labor has repaid that money but the Opposition has also called on it to reimburse the taxpayer for the hundreds of thousands of dollars in legal bills incurred trying to fight the ombudsman in the courts.

The fraud and extortion squad are currently investigating the case.

Parliament resumes on Tuesday for the penultimate session before the election, and Labor will use the document dump to attack Mr Guy.
