Queensland's attorney-general is seeking to have the minimum sentence of a pedophile former magistrate almost doubled.
Crown prosecutors on Thursday began an appeal of the four-and-a-half years' jail handed to William John Randall last November, following conviction over 18 charges at Brisbane District Court.
Randall, who retired in 2016 from the Small Claims Tribunal, continues to claim innocence but the jury found he had abused the boy from age five to 17, starting in 1990.
The victim was 30 before he told police.
Crown prosecutor Todd Fuller QC told the Queensland Court of Appeal Randall's maximum nine-year sentence should be raised to 10 years.
Under the sentencing regime, this would up his non-parole period from four-and-a-half-years to eight years as he would have to serve at least 80 per cent of the head sentence.
Part of the prosecution's argument focused on whether Randall's crimes were aggravated because he was a judicial officer and should have been aware of the lifelong, grave results of abuse, given his former role.
