Immigration Minister Peter Dutton would be given stronger powers to override independent Administrative Appeals Tribunal decisions on citizenship applications under new laws to be introduced to Parliament in the next fortnight.

Mr Dutton said the AAT currently has the ability to make decisions against Australia's national interest by ignoring his department's advice and overturning government deportation orders.

The Greens have labelled the move a power grab by Mr Dutton and said the "draconian measure" aimed to undermine multicultural Australia.

But the Immigration Minister argued the changes would merely address an "anomaly" and allow him to deny citizenship to people with a criminal record.
