lodging a plea for pardon with Governor of Queensland Quentin Bryce. Butler's application was based upon new evidence by forensic scientist and blood group specialist Professor Barry Boettcher, who said, "I can't say Wayne Butler is innocent. All I can say is that the laboratory results are wrong." A hearing for the second appeal was due in early 2007. The appeal was eventually heard by the Court of Appeal in 2009, and it was dismissed on 1 May 2009. Justice Patrick Keane did not regard Professor Boettcher's views as apt to cast doubt on the integrity or competence of John Tonge Centre staff - "There has never been any suggestion that the semen found on the red towel might reasonably be thought not to be that of the killer. I am satisfied there is no reasonable doubt Mr Butler's semen was on the red towel". President of the Queensland Court of Appeal Margaret McMurdo and Judge of Appeal Catherine Holmes agreed.
