(AAP) The Law Council of Australia has argued that it is a slippery slope to detain people because they may commit a future offence under current terrorism laws.
Council president Tass Liveris told an inquiry into the laws that it was impossible to assess such a threat.
“The Law Council is not aware of any empirically validated methodology which would help courts and judges accurately assess this risk,” he said on Thursday.
The Independent National Security Legislation Monitor is scrutinising laws that allow high-risk terrorists to be kept in jail beyond their sentences.
Representatives of the Department of Home Affairs, the Attorney-General’s Department and the Australian Federal Police also appeared before the hearing in Canberra on Thursday.
