A Victorian man with firearm convictions, who was once cleared of murder due to mental impairment, has had his latest bid for a gun licence rejected.
The man, who can only be identified as ZZN, sought a longarm licence so he could hunt on his rural property and euthanise injured or diseased livestock.
But Victoria Police and later, the Firearms Appeals Committee, refused his application, given his criminal record and mental health history.
The man represented himself at the Victorian Civil and Administrative Tribunal (VCAT) to challenge the ruling but it backed the earlier decisions to refuse the licence.
The man had a history of drugs, burglary and firearms-related crimes and was found not guilty of murder in 1993, by reason of mental impairment. He was jailed at Thomas Embling hospital until release in 2002.
The tribunal was told ZZN contacted police in 2009, believing he was being listened to or monitored, and the local mental health services held concerns.
The following year, he was convicted of firearms offences and admitted to a psychiatric facility as an involuntary patient for a number of days.
In 2014 he was found with toy guns in his car and according to police, "appeared to be obsessing about police equipment and weaponry".
VCAT senior member Anna Dea said she wasn't satisfied the man was a fit or proper person to be licensed.
She said ZZN also did not want to provide the tribunal with proper evidence about his mental health history and failed to acknowledge his relevant convictions, believing they were "the result of a police conspiracy and overreaction".
"A history of mental illness combined with violence directed towards others is an obviously relevant and important factor to take into account," she said, in her judgement.
