The decision to charge the accused Christchurch gunman under the Terrorism Suppression Act risks giving the accused a "megaphone" to spout his white supremacist views, a law expert says.
University of Auckland Law Professor Bill Hodge told Newstalk ZB's Heather du Plessis-Allan the charge, laid on May 21 by police, was risky as it had never been applied before in New Zealand.
It would give the accused the platform he wanted to read his manifesto, Hodge said.
"We're stepping into unknown territory," he said. "Murder is cut and dried, every law student knows the definition, every law student knows the act and the mentality whereas this has never been tested before in New Zealand."
The accused had already been charged with 51 counts of murder and 40 of attempted murder, and a terrorism charge would not add to his sentence, Hodge said.
