A federal public servant found guilty of raping and assaulting his ex-wife is set to face a second trial after a jury returned hung verdicts to other alleged sexual crimes.
Justin Isaac Benn has been in custody since an ACT Supreme Court jury found him guilty of sexual intercourse without consent and assault occasioning actual bodily harm earlier this month.
Benn identified himself as an assistant director at the Department of Health and Aged Care while giving evidence in court.
