During Australia’s recent debate about its new Anti-terrorism Act there was discussion about a sunset clause (to ensure that the law would expire after a set period of time). Although there was argument for a 5 year sunset period, the provisions will sunset after 10 years and will be reviewed by COAG after 5 years.
It is interesting to look at the US review process for its anti-terrorism laws introduced after the 11 September 2001 attacks.
Whilst it is possible that an extension may be negotiated, the US public is concerned about alleged privacy and civil liberties breaches by the Bush Administration.
