A white supremacist who killed 51 people at two mosques in New Zealand is appearing in court seeking to overturn his guilty plea.

Brenton Tarrant, serving a life sentence without parole, admitted to the 2019 attacks on worshippers during Friday prayers in Christchurch. Initially denying the charges, he changed his plea a year later.

The 35-year-old has launched an appeal, filed late, arguing that he was incapable of making rational decisions at the time due to conditions he describes as 'torturous and inhumane' in prison.

In addition to contesting his plea, Tarrant also wishes to appeal against his sentence. The proceedings at New Zealand's Court of Appeal in Wellington are set to last all week, with Tarrant expected to provide evidence via video link.

The brutal massacre led to overhauls in New Zealand’s gun laws. The live-streamed shootings resulted in significant legislative action aimed at preventing similar incidents in the future.

'He wants to open traumas again'

Victims and family members will have the opportunity to view the hearing via delayed broadcast. One survivor, Aya al-Umari, who lost her brother in the attack, expressed her concerns about reopening wounds, stating that Tarrant’s actions were a bid for attention and relevance.

During the 2020 sentencing, former Prime Minister Jacinda Ardern emphasized that Tarrant would have no platform or notoriety, highlighting society's desire to move forward. However, the upcoming court proceedings threaten to bring back traumatic memories for many.

If the court allows Tarrant to withdraw his guilty plea, it may lead to a retrial on all charges. If his request is denied, another hearing will take place later this year to address his appeal against the sentence.

Tarrant, originally from Australia, relocated to New Zealand and began planning his acts against the Muslim community, a fact that emerged during the investigations following the massacre.

In recent months, a renewed focus on Tarrant’s motivations and the implications of his actions continues to resonate, with family members directly impacted expressing their struggle with the ongoing legal saga.
