Gladys Berejiklian, the former Premier of New South Wales, has initiated civil legal proceedings against the Independent Commission Against Corruption (ICAC).

Following a more than two-year investigation into her conduct, the ICAC found Berejiklian and ex-Liberal MP Daryl Maguire had engaged in serious corrupt conduct during their relationship, although no criminal charges were recommended.

Supporters of Berejiklian had been pushing for an appeal, and she had indicated her legal team was reviewing the findings. 

In August, an inquiry cleared the ICAC of maladministration in relation to the lengthy investigation, known as Operation Keppel.

Gail Furness SC, the ICAC inspector, investigated the delay and media presence surrounding the probe, concluding that while the delay had an “enormous” impact, it did not constitute maladministration.

Operation Keppel had examined Maguire's conduct during his time as the member for Wagga Wagga and exposed the “close personal relationship” between him and Berejiklian.

Former NSW Treasurer Matt Kean, a supporter of Berejiklian, criticised the ICAC's process and called for its reform just days before the report's release. He now suggests that this legal action will test whether ICAC has acted within the law.

The matter is scheduled for a directions hearing at the Court of Appeal on October 9. 

Premier Chris Minns has expressed no concern about Berejiklian's decision to take legal action, stating that it is her right as a citizen to do so.
