Sydney: Australia is poised to bar its citizens who have fought for the Islamic State militant group from returning home for up to two years, under new laws discussed in parliament Tuesday. The controversial legislation would give hardline Home Affairs Minister Peter Dutton the ability to invoke “exclusion orders” to prevent suspected terrorists from returning to the country. It is based on similar legislation introduced in the United Kingdom, where a judge is tasked with deciding whether to impose an exclusion order.

Concerns have been raised that the Australian proposal could be unconstitutional and places too much power in the minister’s hands, with the opposition Labor Party calling for it to be referred back to a parliamentary intelligence and security committee for further consideration.

It is one of several controversial measures being considered by parliament in the first legislative sitting week since Australia’s conservative government was re-elected in May. Other proposals include repealing the so-called “Medevac” law that allows sick asylum seekers and refugees held in Pacific camps to be brought to Australia for medical treatment. The opposition has to date appeared reluctant to back a repeal of the law, with Labor leader Anthony Albanese telling Sky News on Tuesday he did not believe the government had made a case for change.
