The Green Party and a prominent defence lawyer are calling for an Independent Criminal Appeals Review Office to be set up to look at cases where questions remain over convictions for serious crimes.
The suggestion follows a public meeting by the author of a book which questions the way the police and the justice system handled the double murder convictions of Scott Watson.
Watson is serving a life sentence with a 17-year-non parole period for the 1997 murders of Ben Smart and Olivia Hope and has always maintained his innocence.
The Green Party attended the meeting run by Keith Hunter, who wrote Trial by Trickery and is demanding an Independent Criminal Appeals Review Office be set up.
Scott Watson's lawyer Greg King is backing the call.
Olivia Hope's father Gerald Hope says he would not object to an inquiry, as books and films have generated additional doubt in people's minds and will no doubt continue to do so.
