A Tasmanian man jailed for trying to kill his then-girlfriend by setting her on fire is appealing his attempted murder conviction and sentence, claiming a jury member in his trial was "contaminated" by a "law officer".
Matthew John Davey, 39, is serving 18 years' jail for the crime after being found guilty by a jury last year.
It was told he threw a mixture of petrol and diesel over the then-20-year-old in a shed at a home in Chigwell in April 2017 before igniting it with a cigarette lighter.
She suffered catastrophic burns to 68 per cent of her body, most of which were full-thickness or third-degree, and has been left with significant permanent scarring.
In sentencing remarks, Justice Michael Brett said Davey had "engaged in a continuous and marked pattern of coercive control".
Davey appeared via video link in the Supreme Court of Tasmania in Hobart on Wednesday having lodged an appeal in December against his conviction and sentence.
In the one-page claim, Davey says he was unfairly represented by his defence.
He said he would provide sworn evidence from an expert witness that a law officer perverted the course of justice, contaminating a juror to convict him.
The matter was adjourned until March so Davey's lawyer has more time to review the trial transcript.
Davey's 18-year jail term also covers charges of persistent family violence, to which he pleaded guilty.
He is serving 22 years in total, with a non-parole period of 14 years and three months, after also being convicted of gun and drug trafficking.
Davey constantly monitored his partner's whereabouts and tracked her using electronic surveillance, regularly threatening her verbally.
"On a number of occasions you made it clear to her that if she ever left you, you would find and kill her," Justice Brett said in December.
"You described to her the very specific ways that you would do this."
The woman told Davey in the shed that their relationship was over.
Davey testified during the trial that the woman threw the fuel over herself as a gesture of an intention to take her own life.
