A man who had previously been accused of raping a teenager had worked as a children's tutor in Victoria and WA until it was discovered he did not have police clearance.
The man was working for a tutoring company in Perth until the middle of last year, when it was revealed he did not have a working with children clearance, according to documents from WA's State Administrative Tribunal.
After he applied for the legal right to work with children, the rape charges were revealed, and WA's Department of Child Protection refused his application.
Although he was acquitted of the charges in 1999, SAT deputy president Judge David Parry said the case against him was strong.
The man appealed to the SAT to try and have the refusal overturned, claiming himself as a "man of high moral character and integrity".
Earlier this week, the SAT refused the application, saying in their view the man, named only as 'M', posed "an unacceptable risk".
"There is an unacceptable risk that the applicant might, in the future, cause sexual or physical harm to children in the course of carrying out child-related employment," it said.
In his ruling, Judge Parry revealed the man was alleged to have raped a 15-year-old girl three times in January 1998, after she and a friend were forced into a car at a shopping centre in north Perth.
The case collapsed after the girl's friend consistently failed to appear in court to give evidence - and eventually committed suicide.
Judge Parry concluded: "While he was acquitted on all charges, as we found earlier, the case against him was strong".
The SAT judgment also revealed the man's criminal record included convictions for unlawful assault, threats to kill, using threatening words and behaviour, reckless driving causing injury, disorderly conduct and driving under the influence of alcohol.* Readers seeking support and information about suicide prevention can contact Lifeline on 13 11 14 or the Kids Helpline 1800 55 1800 (for young people aged 5 to 25).
