The man behind the deadliest mass shooting in New Zealand's history has appealed his convictions and life without parole prison sentence, following claims by his lawyer that he received “inhumane and degrading” treatment while in custody.In 2020 he pleaded guilty to 51 murder charges, 40 charges of attempted murder, and a terrorism charge, and was subsequently sentenced to life without parole—a sentence that had never been imposed in New Zealand before.Judge Cameron Mander declared at the time that he was passing down the harshest possible term for the shooter’s “inhuman” actions, telling him: “Your crimes are so wicked, that even if you are detained until you die it will not exhaust the requirements of punishment and denunciation.”On Tuesday, the New Zealand Court of Appeal confirmed to the New Zealand Herald that the attacker had filed an appeal against his conviction and sentence.“By this, he means he was subject to inhuman or degrading treatment whilst on remand, which prevented a fair trial.”Massacre survivors have expressed shock at the appeal, which they say has the potential to re-traumatise those impacted.He’s trying to not be forgotten.”“It’s not going to work and he will remain in there forever.”When asked about the appeal, New Zealand prime minister Jacinda Ardern refused to comment on what she described as the gunman’s “attempts to re-victimize people.”“I made a pledge a long time ago I wouldn’t publicly-name the terrorist from March 15 and that’s because his is a story that should not be told,” Ardern said."
