Despite the issues in his conviction, Mallard's appeal to the Supreme Court of Western Australia in 1996 was dismissed. In 1998, Mallard's family enlisted the help of investigative journalist Colleen Egan, who in turn managed to get John Quigley MLA and Malcolm McCusker QC involved. All were appalled at the manner in which Mallard's trial had been conducted and eventually came to be convinced that he was innocent. Based on fresh evidence uncovered by this team, including a raft of police reports that, against standard practice, had never been passed to the defence team, the case was returned to the Court of Criminal Appeal in June 2003. Despite the fresh evidence and an uncontested claim that the DPP had deliberately concealed evidence from the defence, the Court of Criminal Appeal again dismissed the appeal.
