Opposition Chief Peter Dutton has floated the concept of amending the Australian Structure to permit authorities ministers to strip twin residents of their Australian citizenship in the event that they commit critical crimes associated to terrorism.
Nearly instantly, Dutton’s coalition colleague and Shadow Lawyer-Basic Michaelia Money walked again the concept, saying the Coalition had “no plan” for a referendum.
Twin residents can already lose their Australian citizenship in the event that they commit terrorism offences.
So what does the Structure say in regards to the challenge?
Citizenship cessation
Beneath the Australian Citizenship Act, there are three important methods an Australian citizen can stop their Australian citizenship.
First, a twin citizen can voluntarily resign their Australian citizenship. Some individuals select to do that in the event that they transfer abroad and don’t intend to return to Australia.
Second, the federal government can revoke a twin citizen’s Australian citizenship in the event that they obtained it by fraud. The logic right here is that the particular person was by no means actually eligible for Australian citizenship within the first place.

Third, and most critically, a court docket can – if the federal government asks it to – strip a twin citizen of their Australian citizenship as a part of the sentencing course of for critical crimes resembling terrorism and international incursions.
In deciding whether or not to impose this punishment, the court docket have to be glad the particular person’s crime was “so critical and important that it demonstrates that the particular person has repudiated their allegiance to Australia”.
In different phrases, twin citizen terrorists can already lose their Australian citizenship.
What does the Structure say?
Federal parliament could make legal guidelines solely on sure topic issues, as listed within the Structure. A kind of topic issues is “naturalisation and aliens”.
In a 2022 case referred to as Alexander, the Excessive Courtroom confirmed the naturalisation and aliens energy permits the federal parliament to move legal guidelines taking away an individual’s citizenship if the particular person has achieved one thing that exhibits they’d repudiated their allegiance to Australia.
That case involved an Australian-Turkish twin citizen who travelled to Syria to struggle with the Islamic State militant group. That form of voluntary conduct clearly repudiates allegiance to Australia.

However to be legitimate, a federal regulation should not solely fall underneath one of many listed topic issues resembling “naturalisation and aliens”, it additionally should not breach any limitation on the federal parliament’s energy.
An essential limitation on the federal parliament’s lawmaking energy is protecting federal judicial energy separate from the ability of the parliament and the chief. That is referred to as the “separation of powers”.
The separation of federal judicial energy is a vital constitutional idea. The thought is that it prevents the parliament or authorities ministers interfering within the function of the courts or usurping the function of the courts.
Makes an attempt at laws
Solely courts can train federal judicial energy. Judicial energy contains issues like imposing punishments on individuals for prison conduct. That is the place previous citizenship stripping legal guidelines have run into bother.
The issue with the regulation within the Alexander case was that it allowed a authorities minister to remove the terrorist’s Australian citizenship, reasonably than a court docket, and even when the particular person had not been first convicted by a court docket.
So whereas the Excessive Courtroom dominated the parliament may legislate underneath the aliens energy, it discovered ministers can not determine guilt or punishment.
The federal government thought the issue with the regulation was merely the dearth of prison conviction. So the parliament handed a brand new regulation permitting a authorities minister to strip twin citizen terrorists of their Australian citizenship, however provided that they’d first been convicted by a court docket.
However the Excessive Courtroom struck down that regulation in a 2023 case referred to as Benbrika.

Benbrika had been convicted of terrorism offences within the courts, then a authorities minister made an order taking away his citizenship.
The issue with the regulation, the Excessive Courtroom stated, was {that a} authorities minister was imposing a punishment. Solely courts can impose punishment underneath the separation of powers.
So in response to that call, the federal parliament handed one other regulation. This time the brand new regulation allowed the courts to strip a twin citizen of their Australian citizenship as a punishment as a part of the sentencing course of for critical crimes like terrorism.
That is the regulation that’s at the moment in place. It avoids the separation of powers challenge. There isn’t any constitutional drawback with courts imposing punishment for crimes.
So what does Peter Dutton wish to do?
Peter Dutton’s feedback counsel he desires authorities ministers – reasonably than courts – to impose the punishment of eradicating citizenship. He hasn’t stated why or what objective this is able to serve, other than “protecting our nation secure”.
The one method to permit federal ministers to impose punishments is to alter the Structure by means of a referendum that inserts a brand new provision overriding separation of powers guidelines.
Given Australia’s lengthy historical past of defeated referendums, such a vote is unlikely to succeed.
That’s if it makes it out of the gate. Reported tensions inside the Liberal social gathering counsel it might not get off the bottom to develop into official Coalition coverage.
