Convicted murderer Susan Neill-Fraser will learn on Thursday whether her last-ditch bid to appeal against her conviction has been successful.
Under new state legislation introduced in 2015, Neill-Fraser was given a final appeal attempt provided she could produce "fresh and compelling" evidence.
If successful in her application, Neill-Fraser will be granted a final appeal.
Justice Michael Brett will hand down his judgment at the Supreme Court in Hobart on Thursday at 4pm.
Neill-Fraser is serving a 23-year jail sentence for the murder of her partner Bob Chappell, who disappeared off the couple's yacht, the Four Winds, moored in Sandy Bay on Australia Day 2009.
Mr Chappell's body and a murder weapon were never found.
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.
The final witness in the appeal bid, former Victoria Police detective Colin McLaren, appeared before the court in February, however, last week information in a 60 Minutes segment relating to Neill-Fraser's case re-opened the appeal bid.
The 60 Minutes episode, which was not broadcast in Tasmania, contained evidence of a new affidavit by key witness Meaghan Vass, which allegedly contained information about the events that took place on the Four Winds.
This affidavit, and another sworn by the witness to Ms Vass's affidavit, were to be made available to Justice Brett for consideration before delivering his decision on Thursday.
