Jackie Trad on Thursday took aim at Queensland's Liberal National government after high-profile Crime and Corruption Commission reports were tabled in parliament, fulfilling an election commitment.
The LNP had promised to publicly release reports on former Labor MP Ms Trad and ex-public trustee Peter Carne following its 2024 poll triumph, after the documents were shelved for years.
The commission's 2021 report tabled on Wednesday night said Ms Trad's "aggressive advocacy" influenced a Queensland Treasury chief executive appointment.
However, the report did not find evidence of corrupt conduct by Ms Trad.
The former deputy premier criticised the LNP government for releasing the report which had been under wraps since a 2023 High Court ruling, calling it "political point scoring".
"The tabling of the unlawful CCC reports in the Queensland parliament is a direct measure of the lack of respect the Queensland LNP government holds for the courts, including the High Court of Australia," she posted on social media.
"This also sets a dangerous precedent for a government; to use their numbers in parliament to set aside and disregard a well-considered, balanced and fair judgement from the highest court in our nation, without legislative amendment or scrutiny.
"For the LNP government to now release the reports against the judgement of the High Court ... for the purposes of political point scoring is both terrifying and petty."
The commission's report said Ms Trad's "forcefully expressed personal preference" had influenced the independent recruitment process of the Queensland Treasury chief executive in 2018.
Ms Trad denied the allegations in the report, with the commission noting there was insufficient evidence to support prosecution against her.
She took aim at the commission on Thursday, saying its report was full of "subjective character judgments".
Ms Trad said she approached the commission in 2023 to settle the matter but claimed it did not respond and chose to go to the High Court.
"Every single member of the full bench of the High Court resoundingly found against the CCC," she posted.
"The fact the CCC have so fundamentally misunderstood the legislation governing the exercise of their enormous and expansive powers is both deeply concerning and an embarrassment."
The High Court ruled the commission's report into Mr Carne was not subject to parliamentary privilege and could not be released.
Ms Trad then won a court battle to keep secret the watchdog's report on her after all parties accepted the state's law would not allow its release in October 2023.
However the commission's reports on Ms Trad and Mr Carne were made public after the LNP government brought a motion for its release in state parliament on Wednesday night.
Queensland parliament on Thursday was told former Attorney-General Shannon Fentiman signed off on $380,000 in taxpayers' money to fund Ms Trad's court battle to keep the commission's report secret.
Ms Fentiman said use of the funds had been approved by the state's legal counsel.
Elected in 2012, Ms Trad served as deputy premier and treasurer before standing down in 2020 due to a separate commission probe, losing her seat at the state election the same year.
