A panel of three judges will be appointed to hear the appeal against Lloyd Rayney's acquittal over the alleged murder of his estranged wife and former Supreme Court registrar Corryn.
Attorney-General Michael Mischin has confirmed that Victoria Court of Appeal Justice Mark Weinberg has been seconded to deal with the preliminary stages of the appeal process.
But a decision is yet to be made on whether the other two judges required to determine the appeal will be appointed from within the existing WA Supreme Court bench or from other jurisdictions.
The hearing is expected to run for two or three days and has not been listed by the court, but it could be held as early as May.
Mr Rayney, a prominent barrister who recently gave an undertaking he would stop engaging in legal practice, was found not guilty on November 1 of the wilful murder or manslaughter of his wife.
During a 12-week, judge-alone trial, prosecutors accused Mr Rayney of murdering his wife at their Como home on August 7, 2007, and burying her in Kings Park.
Because of the estranged couple's close ties to the legal community, the trial was prosecuted by a team from NSW and heard by former Northern Territory Supreme Court chief justice Brian Martin.
Justice Martin found that while some evidence raised a "strong suspicion" against Mr Rayney, the prosecution case was not proved beyond reasonable doubt and contained "critical gaps".
The appeal includes claims that Justice Martin did not consider the circumstantial case as a whole and erred by adopting a "piecemeal" assessment.A successful appeal could result in Mr Rayney facing a retrial.
