The legal team for the convicted double-murderer Scott Watson is gathering a team to research the evidence against him and clear his name.
Watson is serving a minimum non-parole period of 17 years after being convicted in 1999 for the murders of Ben Smart and Olivia Hope.
His father Chris Watson said for the past three months, Watson's lawyers had been assembling a team of researchers, scientists and a private investigator.
Mr Watson said the success of the Teina Pora case at the Privy Council leads his son's legal team to hope it can do the same.
"We're hoping that they will achieve at least a better understanding of the evidence that was there and some new aspect of it that may not have existed earlier in the piece.
"I mean there's a greater understanding of DNA evidence. We could go back to the Governor-General with that and hopefully get the conviction overturned."
In July 2013, the Governor-General declined an application from Scott Watson to be pardoned after unsuccessful appeals to the Court of Appeal and the Privy Council.
