Convicted murderer Susan Neill-Fraser has lost her latest bid for freedom, with a Tasmanian court dismissing the Hobart grandmother's appeal.
The 67-year-old was found guilty in 2010 of murdering Bob Chappell on the couple's yacht while it was moored off Hobart on Australia Day the year prior.
She was sentenced to 23 years' jail but launched an appeal several years ago under new laws based on the argument there was "fresh and compelling" evidence in the case.
Tasmania's Court of Criminal Appeal dismissed her appeal on Tuesday.
Two of the three judges on the deciding panel, Justice Helen Wood and Robert Pearce, dismissed the appeal, although Justice Stephen Estcourt said he would order a retrial.
"After careful consideration of this appeal I have reached the conclusion that the evidence relied upon ... is not fresh, not compelling," Justice Wood said.
"There has not been a substantial miscarriage of justice."
