People in NSW will no longer have the "right to silence" when being questioned by police after the Shooters and Fishers Party voted with the government on its bid to combat gang violence.
Critics of the laws - which the government will now push through the lower house - say it's a fundamental attack on people's rights.
The legislative changes allow judges and juries to take a negative view of people who exercise their right to remain silent.
The government flagged the move last August following a spate of drive-by shootings in Sydney.
NSW Police Commissioner Andrew Scipione denied the legislation would infringe on a person's basic rights.
"This is simply a matter of trying to level the playing field," he said. AAP
