A former Speaker of the house is being taken to the High Court for musical torture during the 2022 anti-mandate protest.
A girl from Northland, who was 11 at the time, says Mallard weaponised songs like Disney's Let it Go - causing mental anguish, humiliation and de-humanisation.
Her lawyer, Tudor Clee says blasting someone with music is a military-style torture technique.
He says this is the first time this technique has been intentionally used on children.
The girl is seeking 40 thousand dollars in damages.
