Nine years after being convicted for the murder of her partner Bob Chappell, Susan Neill-Fraser has been successful in gaining a final appeal.
Justice Michael Brett handed down the verdict on Neill-Fraser's last-ditch appeal bid in the Supreme Court in Hobart on Thursday.
Neill-Fraser was sentenced to 23 years' jail for the murder of Mr Chappell, who disappeared on Australia Day in 2009.
Mr Chappell disappeared from the couple's yacht, the Four Winds, which was moored in the Hobart suburb of Sandy Bay.
Mr Chappell's body and a murder weapon were never found.
Neill-Fraser was convicted on circumstantial evidence and was found unanimously guilty by a jury in 2010.
Neill-Fraser maintains she is innocent of murdering Mr Chappell and has previously unsuccessfully appealed in the Court of Criminal Appeal and attempted to address the matter in the High Court.
Under new state legislation introduced in 2015, Neill-Fraser was able to bid for a final appeal provided she could show the court "fresh and compelling evidence".
The appeal concluded in February, however, was re-opened last week to allow Justice Brett to consider new information allegedly brought to light in a segment on the television program 60 Minutes.
The 60 Minutes segment contained evidence of a new affidavit by key witness, Meaghan Vass, which allegedly held information about the events that took place on the Four Winds the night Mr Chappell disappeared.
Ms Vass's DNA was found on the Four Winds yacht and she previously said in an affidavit Neill-Fraser was not on the yacht when Mr Chappell disappeared.
However, she later told the court she was threatened to make the affidavit.
Neill-Fraser's appeal was re-opened in order to consider the new affidavit sworn by Ms Vass and a second affidavit sworn by the witness to Ms Vass's statement in order to explain the circumstances of Ms Vass' affidavit.
Last week, the court heard Justice Brett would consider the two new affidavits before handing down his judgment on Thursday.
