WA lawyer referred to regulator after preparing documents with AI-generated citations for nonexistent cases
It is one of more than 20 cases so far in Australia in which AI use has resulted in fake citations or other errors in court submissions, with warnings from judges across the country to be wary of using the technology in the legal profession.
In a federal court judgment published this week, the anonymised lawyer was referred to the Legal Practice Board of Western Australia for consideration and ordered to pay the federal government's costs of $8,371.30 after submissions to an immigration case were found by the representative for the immigration minister to include four case citations that did not exist.
Justice Arran Gerrard said the incident 'demonstrates the inherent dangers associated with practitioners solely relying on the use of artificial intelligence in the preparation of court documents and the way in which that interacts with a practitioner's duty to the court'.
The lawyer told the court in an affidavit that he had relied on Anthropic's Claude AI 'as a research tool to identify potentially relevant authorities and to improve my legal arguments and position', and then used Microsoft Copilot to validate the submissions.
The lawyer said he had 'developed an overconfidence in relying on AI tools and failed to adequately verify the generated results'.

'I had an incorrect assumption that content generated by AI tools would be inherently reliable, which led me to neglect independently verifying all citations through established legal databases,' the lawyer said in the affidavit.
The lawyer unreservedly apologised to the court and the minister's solicitors for the errors.
Gerrard said the court 'does not adopt a luddite approach' to the use of generative AI, and understood why the complexity of migration law might make using an AI tool attractive. But he warned there was now a 'concerning number' of cases where AI had led to citation of fictitious cases.
Gerrard said it risked 'a good case to be undermined by rank incompetence' and the prevalence of such cases 'significantly wastes the time and resources of opposing parties and the court'. He said it also risked damage to the legal profession.
Gerrard said the lawyer did 'not fully comprehend what was required of him' and it was not sufficient to merely check that the cases cited were not fake, but to review those cases thoroughly.
'Legal principles are not simply slogans which can be affixed to submissions without context or analysis.'
There have been at least 20 cases of AI hallucinations reported in Australian courts since generative AI tools exploded in popularity in 2023.
Last week, a Victorian supreme court judge criticised lawyers acting for a boy accused of murder for filing misleading information with the courts after failing to check documents created using AI.
The documents included references to nonexistent case citations and inaccurate quotes from a parliamentary speech.

There have also been similar cases involving lawyers in New South Wales and Victoria in the past year, who were referred to their state's regulatory bodies.
However, the spate of cases is not just limited to qualified lawyers. In a NSW supreme court decision this month, a self-represented litigant in a trusts case admitted to the chief justice, Andrew Bell, to have used AI to prepare her speech for the appeal hearing.
Bell said in his judgment that he was not criticising the person, who he said was doing her best to represent herself. But he said problems with using AI in preparing submissions were exacerbated when the technology was used by unrepresented litigants 'who are not subject to the professional and ethical responsibilities of legal practitioners'.
He said the use of generative AI tools 'may introduce added costs and complexity' to proceedings and 'add to the burden of other parties and the court in responding to it'.
'Notwithstanding the fact that generative AI may contribute to improved access to justice, which is itself an obviously laudable goal, the present case illustrates the need for judicial vigilance in its use, especially but not only, by unrepresented litigants.'
The Law Council of Australia's president, Juliana Warner, said sophisticated AI tools offered unique opportunities to support the legal profession in administrative tasks, but reliance on AI tools did not diminish the professional judgment a legal practitioner was expected to bring to a client's matter.
'Where these tools are utilised by lawyers, this must be done with extreme care,' she said. 'Lawyers must always keep front of mind their professional and ethical obligations to the court and to their clients.'
Warner said courts were regarding cases where AI had generated fake citations as a 'serious concern', but added that given the widespread use of generative AI, a broadly framed prohibition on its use in legal proceedings would be 'neither practical nor proportionate, and risks hindering innovation and access to justice'.

DHS Secretary says entire southern border wall to be painted black to stop people from climbing it
Homeland Security Secretary Kristi Noem said Tuesday that the entire border wall along the southern border with Mexico is going to be painted black to make it hotter and deter illegal immigration — and she credited President Trump with the idea. Noem spoke during a visit to a portion of the wall in New Mexico, where she also picked up a roller brush to help out with the painting. She touted the height of the wall as well as the depth as ways to deter people seeking to go over or under the walls. And then Noem said Homeland Security was going to be trying black paint to make the metal hotter. 'That is specifically at the request of the president, who understands that in the hot temperatures down here when something is painted black it gets even warmer and it will make it even harder for people to climb. So we are going to be painting the entire southern border wall black to make sure that we encourage individuals to not come into our country illegally,' Noem said. U.S. Border Patrol Chief Mike Banks, who attended the event with Noem, said the paint would also help deter rust. During Trump's first term, building the wall was a central focus of his hardline immigration policy. During his second term, his mass deportation agenda with arrests in the interior of the country has been the main focus, but Homeland Security will be getting about $46 billion to complete the wall as part of new funding passed by Congress this summer. Noem said they have been building about a half mile of barrier every day. 'The border wall will look very different based on the topography and the geography of where it is built,' she said. She said that in addition to barriers like the one she visited Tuesday, the department is also working on 'water-borne infrastructure.' Long sections of the roughly 2,000-mile border between the U.S. and Mexico sit along the Rio Grande River in Texas. The Trump administration is pushing forward with completing the wall at the same time that the number of people crossing the border illegally has plummeted.

Labour's war on Middle England: Rural areas could foot the bill to pay for Rayner's reforms of council tax
Middle England will be hit by the highest possible increases in council taxes to pay for 's reforms to the system, town hall leaders have warned. Households in the countryside will reportedly be charged at unfairly high levels to pay for residents of cities under the Communities Secretary's 'fair funding' plans. Last night, Tory leader Kemi Badenoch branded it a 'spiteful' move that will push more cash into traditional Labour areas. Analysis by the County Councils Network (CNN) found rural and county local authorities will lose close to half a billion pounds in Government cash over the next three years thanks to Ms Rayner's attempt to level up the system. This will force them to cut vital services and hike bills for hard-pressed residents by the maximum 5 per cent allowed. The CCN demanded an urgent injection of cash from Whitehall to fill the gap, warning town halls on the brink would otherwise be unable to provide crucial care for the elderly and vulnerable children. It comes after almost all town halls raised bills by the maximum amount earlier this year to deal with soaring demand and costs, taking the average bill to £2,280. Chairman of the group, councillor Tim Oliver, said: 'Some 16 county and rural councils will see reductions in grant funding, while the Government's proposals place a disproportionate burden on taxpayers in county areas to fund local services and redistribute funding to urban areas. 'It's vital the Government makes more money available to mitigate the impact of these reforms.' Ms Badenoch said: 'Yet again the Labour Government is showing utter contempt for people living in rural Britain. 'The family farms tax has been devastating, and scrapping the rural services grant has put rural councils under enormous pressure. 'This latest change will steal more money out of the hands of county councils and send it straight into Labour-run urban areas.' Under Ms Rayner's Fair Funding Review 2.0, the Ministry of Housing, Communities and Local Government (MHCLG) will make major changes to how English councils are funded. Her updated formula will allocate cash based on local areas' needs and their ability to raise council tax compared to others around the country. The Institute for Fiscal Studies think-tank has already warned it will create big winners and losers, with those in the home counties likely to suffer budget cuts unless council taxes rise. In its response to the MHCLG consultation, published last night, the CCN said it would mean 16 authorities – including some in the Midlands and North – losing £470million of funding over the next three years. In total, county and unitary councils' grant funding will rise by just £374million. Unless 33 of the 38 town halls impose the maximum 5 per cent council tax rises, they will see a real-terms cut in funding, according to the CCN. Metropolitan authorities will get £1.2billion, and a proposal to redistribute £1.6billion in council tax income will benefit urban areas at the expense of the countryside. An MHCLG spokesman said: 'We do not recognise this analysis. We are taking decisive action to reform the funding system.'

Winston Hills shooting: Young man Osama Momani on bail for violent home invasion identified as victim
The young man killed in Sydney 's most recent fatal shooting has been identified with police confirming a burnt-out car found nearby was linked to the tragic incident. Osama Momani, 22, was shot dead while sitting in a car outside a residence on Regiment Grove in Winston Hills, in Sydney's west about 7pm on Tuesday. Momani was on bail at the time while awaiting trial on charges including aggravated break and enter over an alleged home invasion in Chester Hill in September 2023. Momani suffered chest wounds and was rushed to Westmead Hospital by ambulance, where he later died. Police and fire crews were called to Bounty Place in Old Toongabbie hours later, shortly before 11.15pm, where a Toyota SUV was found alight. The blaze was extinguished by firefighters and no one was injured. Police believe the car was linked to Momani's shooting. Crime scene were established at both locations with the Homicide Squad and local detectives launching Strike Force Karlgain to investigate. It was the second shooting to rock Sydney in two days, after gunmen opened fire outside a busy pub in Forest Lodge during the dinner rush on Sunday. Police sources told the Daily Telegraph they believed Momani's death was not linked to Forest Lodge incident, which claimed the life of Gilbert Shino. More to come.
