Brenton Tarrant’s attempt to appeal his conviction for the 2019 mosque attacks in New Zealand has been denied.
Brenton Tarrant, the gunman behind the 2019 Christchurch mosque attacks, has lost his appeal to overturn his conviction and sentence. A New Zealand court made the decision on Thursday. [source]
Tarrant, who killed 51 Muslim worshippers at two mosques, argued that harsh detention conditions affected his mental health, leading him to plead guilty. However, the court found his appeal to be “utterly devoid of merit.” [source]
The court determined that Tarrant’s guilty pleas were voluntary and not influenced by his prison conditions. The judges pointed out inconsistencies in his claims and referenced assessments by mental health professionals. [source]
Tarrant’s life sentence without parole is the harshest in New Zealand’s history. His attack, which he livestreamed, was the deadliest mass shooting in the country. [source]
The court’s decision followed Tarrant’s attempt to abandon his appeal by submitting notices under pseudonyms. The court dismissed these due to procedural issues. [source]
Lawyers for the victims’ families expressed relief at the court’s decision, stating it spared them the trauma of a new trial. [source]
“The law has now done its job,” said lawyers for the victims’ families.
