A New South Wales man has been awarded more than $300,000 in damages after a District Court judge found that police acted unlawfully when they entered his home, seized firearms, had him detained under mental health powers and later prosecuted him over weapons found during the search.

Michael Camilleri, a Mid North Coast printing business owner, sued the State of New South Wales over events that began on 7 January 2022 after an Australian Taxation Office supervisor contacted emergency services and reported concern that Mr Camilleri had threatened self-harm during a phone conversation.

The court heard that police attended Mr Camilleri’s Port Macquarie home because of the welfare report and because he was a licensed firearms owner. Officers entered the apartment, accessed his gun safe and removed firearms. During the search they also located two butterfly knives, which are prohibited weapons in New South Wales.

Mr Camilleri disputed the claim that he had threatened to harm himself and later argued that police had no lawful basis to enter and search his home in the way they did. The civil case examined not only the initial entry but the steps police took afterwards, including information provided to health staff and the prosecution launched over the knives.

Judge Andrew Scotting found the entry and search were unlawful and rejected the proposition that Mr Camilleri had given valid consent in circumstances that would make the search lawful. According to reporting of the judgment, the judge found that an officer obtained compliance after indicating that police could otherwise obtain a warrant and force entry, despite not having a lawful basis to do so.

The judge also made serious findings about the information supplied when Mr Camilleri was taken for mental health assessment. The court found that false or misleading information was provided for the purpose of influencing medical staff and retrospectively justifying the earlier police conduct.

Mr Camilleri was detained under the Mental Health Act and taken to Port Macquarie Hospital. He was later transferred to Coffs Harbour Base Hospital and remained in involuntary psychiatric detention for four days.

During that period, the court heard, he received sedative and antipsychotic medication and spent time in a locked mental health seclusion room while COVID infection-control measures were in place. He was eventually assessed by a psychiatrist who did not consider him mentally ill at the time of discharge.

The case is significant because police welfare powers and mental health laws are designed to allow urgent intervention where there is a genuine risk to a person or others, but they are not unlimited. The court’s findings focused on whether the legal requirements for entry, detention and subsequent prosecution were actually satisfied in Mr Camilleri’s case.

Judge Scotting found that the detention amounted to false imprisonment and that the criminal prosecution over the butterfly knives was maliciously brought for an improper purpose. Reporting of the judgment said the judge concluded that the prosecution was used in part to try to justify the earlier unlawful search and place Mr Camilleri at a disadvantage in challenging police actions.

Mr Camilleri had previously been convicted in the Local Court of offences connected with the knives, but that conviction was later overturned on appeal in the District Court. He then pursued civil damages against the state.

The damages awarded were broken into several components. The State of New South Wales was ordered to pay $40,000 for trespass, $215,000 for false imprisonment and $30,000 for malicious prosecution. With interest on past damages, the total reached $303,730, in addition to legal costs.

The decision does not mean police can never enter a home or seize firearms when responding to a credible welfare concern. New South Wales law gives police substantial powers in emergencies and in situations involving immediate risks. The judgment instead turned on the particular facts, what officers knew at the time and whether they were legally entitled to do what they did.

That distinction is important because welfare checks often require officers to make rapid decisions with incomplete information. A report of possible self-harm combined with the presence of firearms can reasonably cause concern. But emergency powers still depend on statutory thresholds, and later actions cannot be used to create a legal justification that did not exist at the time.

The court’s findings about consent were therefore central. Consent to police entry or a search must be real rather than the product of a misleading assertion that officers have powers they do not actually possess. If a person complies because police wrongly indicate that resistance would simply lead to a warrant or forced entry, a court may examine whether that compliance amounted to genuine consent.

The judgment also raises broader questions about the interaction between policing and mental health systems. Police regularly transport people for assessment where officers reasonably believe urgent mental health intervention is required. Medical practitioners then make clinical decisions under the relevant legislation.

In Mr Camilleri’s case, however, the civil court found that information provided by police to medical staff was wrong or misleading and that it materially contributed to his detention. That finding is especially serious because involuntary mental health detention removes a person’s liberty through a process that depends heavily on accurate information being supplied at the start.

The four-day detention had consequences beyond the loss of liberty itself. Mr Camilleri told health practitioners he felt he had been treated like an animal and was distressed by being medicated against his will, being unable to freely contact family or a lawyer and by the effect of the incident on his parents.

The civil damages reflect several different legal wrongs rather than a single general payment for an unpleasant experience. Trespass protects the right to control access to property. False imprisonment protects personal liberty against unlawful detention. Malicious prosecution addresses the improper use of criminal proceedings where the required elements are established.

Each cause of action has its own legal test. The fact that Mr Camilleri succeeded on several grounds indicates that the court found problems at multiple stages of the police response rather than identifying only a technical defect in one decision.

There is also an important distinction between this civil case and earlier administrative proceedings involving Mr Camilleri’s firearms licence. In 2024, the New South Wales Civil and Administrative Tribunal considered a separate review concerning whether it was in the public interest for him to hold a firearms licence. That proceeding dealt with administrative licensing questions and should not be confused with the later civil findings about unlawful entry, detention and prosecution.

The District Court judgment is focused on the conduct of police officers and the state’s civil liability. It does not invalidate the broader system used by police to respond to welfare concerns, nor does it prevent authorities from taking firearms into account when assessing an immediate risk.

Instead, the case reinforces that strong powers require accurate factual foundations. Police may face difficult circumstances, but courts can later examine whether an asserted power actually existed, whether consent was properly obtained, whether information was truthful and whether criminal proceedings were commenced for a legitimate purpose.

For the State of New South Wales, the order creates a substantial financial liability and a public record of critical judicial findings. The state may have appeal rights depending on the final orders and procedural position, although no appeal outcome had been reported at the time of publication.

For Mr Camilleri, the damages award follows more than four years of legal consequences arising from the January 2022 incident, including psychiatric detention, criminal proceedings, an appeal and the later civil claim.

The case is likely to be read closely by lawyers dealing with police powers, mental health detention and civil claims against the state because it brings all three areas together. The central lesson from the judgment is not that welfare concerns should be ignored, but that urgent intervention must still be grounded in lawful powers and accurate information.

The financial breakdown of the award also shows how courts assess different forms of harm. The largest component was for false imprisonment, reflecting the seriousness of being deprived of liberty for several days. The separate awards for trespass and malicious prosecution recognised the unlawful interference with Mr Camilleri’s property and the later use of criminal proceedings, while interest compensated for the time that had passed before damages were paid.

Cases involving emergency welfare calls can be particularly difficult because police are often criticised whichever way they act: failing to intervene can have grave consequences, while unnecessary intervention can itself cause serious harm. The legal safeguard is that officers must make decisions within the powers Parliament has given them and must accurately record the facts on which those decisions depend.

The judgment also demonstrates why body-worn video, contemporaneous notes and hospital records can become decisive years later. Civil courts do not assess an incident only through recollection. They compare what officers said at the time, what was recorded, what medical staff were told and what later evidence shows. Where those records conflict, credibility and purpose can become central issues.

Mr Camilleri’s case therefore extends beyond the unusual facts of a firearms owner taken into psychiatric care. It is an example of the legal accountability mechanisms available when a person argues that police powers were exercised without proper authority and that later official steps were used to defend the original conduct.
