Mass murderer Julian Knight has been granted leave to challenge a decision to ban him from access to a computer in his prison cell, which he says he needs to prepare for legal proceedings in the Supreme and High Courts. Knight has been declared a vexatious litigant because he frequently launches futile law suits, which means he now needs the Court’s permission to sue. He is expected to challenge the Corrections Amendment (Parole) Bill 2014 if it is passed, because it names him as the only prisoner who must be denied parole unless his death is imminent. The High Court has previously struck down a NSW law that purported to keep a specific prisoner locked up after his release date. However, the Victorian bill differs in that Knight is serving seven consecutive life sentences, and eligibility for parole is a matter for the executive rather than the judiciary.
