A man jailed for murdering his solicitor in Melbourne has lost a legal battle to have the Victorian coroner investigate the victim's death.
John Thomas Glascott was sentenced to 28 years in prison in 2008 after a Supreme Court jury found him guilty of murdering 56-year-old David Robinson in 2006.
In 2011 he had his sentence reduced by four years on appeal.
Four years later he requested the state coroner investigate the murder "'in the hope that the truth will come out".
The coroner formally refused Glascott's request.
Glascott appealed against the coroner's decision in the Victorian Supreme Court in March during a one-day hearing where he represented himself.
Justice Timothy Ginnane dismissed the appeal on Friday.
Glascott had said there were inconsistencies with the time of Mr Robinson's death.
"The biggest dispute, and why we need a coronial inquest, is the time of death," he told the court on March 27.
"If timings are wrong, the whole case is wrong."
At trial, the jury heard Mr Robinson went to his office with his son on July 10, 2006, intending to help the boy print some homework.
When the lawyer found glass smashed and smouldering papers inside, he went to the rear of the office to investigate.
He was confronted by Glascott who repeatedly shot at him.
Justice Ginnane said Glascott's appeal against the coroner's decision focused on his failed Court of Appeal case, rather than the decision of the coroner.
"This appeal was not the occasion to attack the Court of Appeal's decision and the arguments raised did not require the coroner to decide to hold an inquest," he said in his written reasons.
"There is nothing in any additional matter raised on this appeal, that establishes that the interests of justice require the appeal to be allowed."
