The Home Affairs department has added to its lengthy list of debacles with a train wreck appearance before the Parliamentary Joint Committee on Intelligence and Security (PJCIS) on the government's citizenship-stripping laws that appeared to signal a dramatic change in the way the government views citizenship.

Appearing before the PJCIS on Friday afternoon, officials from the Home Affairs portfolio -- the centre of a number of major bungles in recent years and currently the subject of significant national security concerns over its links with gambling giant Crown -- inflicted significant damage on the government's case for ever-greater powers to strip Australians of citizenship. It was during 2015 hearings into the citizenship-stripping legislation, then in its draft form, that officials of the then-immigration portfolio admitted to major failings around the bill, prepared by the Abbott government to demonstrate its national security credentials.
