The former premier has failed to overturn a finding of serious corrupt conduct after challenging a report by the corruption watchdog in the state's highest civil court.

In short:

  • Former NSW premier Gladys Berejiklian has failed to overturn the finding that she engaged in serious corrupt conduct.

  • Last year, the Independent Commission Against Corruption found Ms Berejiklian breached public trust, while serving as state premier, during her secret relationship with former NSW MP Daryl Maguire.

  • Ms Berejiklian has long insisted she always acted in the public interest, beginning legal action shortly after the corruption watchdog released its report.
