Issues before the court
Whether the appellant owed the respondents a duty of care to prevent injury from criminal violence by third parties on licensed premises
Whether the appellant breached its duty by failing to engage licensed security personnel
Plain English Summary
Two men were shot at a packed New Year's Eve party in a licensed Sydney restaurant after a fight spilled over. The shooter left, got a gun and came back. The victims sued the restaurant owner for not having security staff. The High Court said the restaurant did owe a legal duty to take reasonable steps to stop patrons being hurt by drunken violence because it controlled who came in and was bound by liquor laws to stop fights. But the victims could not prove that hiring licensed security guards would actually have stopped this particular shooter. His actions were irrational and violent; security might have made no difference. Because the Civil Liability Act requires proof that 'but for' the lack of security the harm would not have happened, and this was not shown, the claims failed. The Court emphasised that criminal acts by determined third parties are hard to link causally to a business's omissions.

What happened
On the night of 31 December 2002 into the early hours of 1 January 2003, Adeels Palace, a licensed restaurant in Punchbowl, New South Wales, hosted a New Year's Eve function. Admission cost $60 per person, which included food but not drinks. The premises operated under an On-Licence (Restaurant) issued under the Liquor Act 1982 (NSW), with a seating capacity limited to 295 and an entertainment licence capped at 283 persons. The restaurant was full. A band played, patrons danced at long tables, and alcohol was served until 4 am.
At approximately 2.30 am a minor altercation occurred on the dance floor when one woman accused another of brushing her with a lighted cigarette. Words were exchanged, relatives and friends became involved, punches were thrown, and the disturbance rapidly escalated as onlookers joined in. Chairs, plates and bottles were used as missiles. One participant was struck in the face, drawing blood. He left the premises and returned minutes later armed with a handgun. Someone shouted a warning. Mr Bou Najem ran toward the kitchen but slipped. The gunman followed, pointed the weapon at him while he was on the floor, and shot him in the leg despite pleas for mercy. The gunman then returned to the main dining area, located the man who had struck him, shot him in the stomach (Mr Moubarak), and left.
Both injured men brought proceedings in the District Court of New South Wales alleging that Adeels Palace Pty Ltd, the operator of the business and occupier (with one of its directors being the licensee), had been negligent in failing to provide any or any sufficient licensed security personnel. The actions were heard together. The trial judge found liability and awarded damages. The Court of Appeal (Beazley, Giles and Campbell JJA) dismissed appeals by the operator: Adeels Palace Pty Ltd v Moubarak (2009) Aust Torts Reports ¶81-997.
The High Court granted special leave. The appeals were heard together. The Court (French CJ, Gummow, Hayne, Heydon and Crennan JJ jointly) allowed both appeals with costs, set aside the Court of Appeal orders, and substituted orders allowing the appeals to that Court and entering judgment for the defendant with costs in each proceeding. The critical failures were in proof of breach of duty under s 5B of the Civil Liability Act 2002 (NSW) and, decisively, in proof of factual causation under s 5D.
Why the court decided this way
The joint judgment began by insisting that analysis must start with the two statutes that governed the factual and legal landscape: the Civil Liability Act and the Liquor Act. Part 1A of the Civil Liability Act applied to any claim for damages for harm resulting from negligence, whether in tort, contract or otherwise. Sections 5B and 5C, although placed under the heading "Duty of care", were held to be directed to breach. Section 5B(1) provides that a person is not negligent in failing to take precautions against a risk of harm unless the risk was foreseeable, not insignificant, and a reasonable person in the person's position would have taken those precautions. In deciding the last question the court must consider (among other things) probability, likely seriousness, burden of precautions and social utility.
Section 5D divided causation into two distinct elements: factual causation (the negligence was a necessary condition of the occurrence of the harm) and scope of liability. The "but for" test is the statutory test of factual causation. Only in an exceptional case, determined in accordance with established principles and after considering whether and why responsibility should be imposed, may a court depart from it.
The Liquor Act was central to duty. Section 125(1)(b) made it an offence for a licensee to permit indecent, violent or quarrelsome conduct on licensed premises. Section 103 empowered the licensee or employee to refuse admission to or to turn out violent, quarrelsome or disorderly persons, using reasonable force if necessary, and obliged police to assist. Section 2A declared liquor harm minimisation, including minimisation of violence, a primary object of the Act. These provisions were said to form part of the price exacted for the statutory permission to sell liquor. Analogous provisions exist in every Australian jurisdiction.
Against that background the Court held that Adeels Palace owed each plaintiff a duty to take reasonable care to prevent injury to patrons from the violent, quarrelsome or disorderly conduct of others. Three features distinguished the case from Modbury Triangle Shopping Centre Pty Ltd v Anzil (2000) 205 CLR 254: the complaint was failure to control access to and continued presence on the premises; the premises were licensed for the sale and consumption of liquor where alcohol-related violence is a recognised risk; and the duty asserted mirrored the licensee's statutory obligations. The duty was not absolute and was supported by the statutory powers to exclude or remove persons.
On breach, the Court was sceptical. The plaintiffs had contended that licensed security ("bouncers") should have been stationed both at the street entrance and inside the restaurant. The trial judge and Court of Appeal had focused only on door control. No finding was made that internal supervision was required. The s 5B inquiry had to be undertaken prospectively, before the function began, not with the wisdom of hindsight after a gunman appeared. The evidence of prior incidents was weak (only some reports of threatening conduct by passers-by outside). The demographic of the crowd (families and mixed ages) did not suggest an obvious need for security. The probability that a person who left after a fight would return armed and determined to shoot was not shown to be such that a reasonable person would have engaged licensed security. The burden of doing so (multiple trained personnel under the Security Industry Act 1997 (NSW)) was not inconsequential. Ultimately the Court found it unnecessary to reach a final conclusion on breach because causation was not established in any event.
On causation the reasoning was decisive. The trial judge's reasoning had not been fully articulated; the Court of Appeal reconstructed it as an inference that security staff at the entrance, aware of the fracas and seeing blood on the gunman's face, would have denied him re-entry or required a search. The High Court held that this was not supported by the evidence. Security personnel might deter the drunk or obstreperous, but the gunman was a determined, armed, irrational assailant bent on revenge. His conduct was not dictated by reason or prudential considerations. The plaintiffs' own security expert had gone no further than saying a security person "would have at least altered the chain of events and thereby likely altered the outcome". The defendant's expert emphasised that once a determined gunman targets victims there is "no guaranteed safe or effective option".
Mere possibility that security might have delayed entry, changed the target, or led to intervention was insufficient. The statutory test required the absence of security to be a necessary condition of the harm. That test was not met. The Court refused to treat the case as exceptional under s 5D(2). To do so would depart from established principles merely because the harm was "the very kind of thing" the duty was designed to prevent. That consideration might affect scope of liability but could not dispense with factual causation. The cases were unlike Home Office v Dorset Yacht Co Ltd or Stansbie v Troman where reasonable care would probably have prevented the injury. Nor were they analogous to Fairchild v Glenhaven Funeral Services Ltd. Imposing liability where the "but for" test was not satisfied would mean that negligence that merely made criminal wrongdoing less likely was treated as its cause, contrary to Modbury.
The Trade Practices Act 1974 (Cth) s 74 contention (implied warranty of due care and skill) failed for the same reason: the plaintiffs could not establish that any breach materially contributed to their loss.
Before and after state of the law
Before Adeels Palace the leading High Court authority on liability for the criminal acts of third parties was Modbury Triangle. There the occupier of a shopping centre was held not to owe a duty to keep car-park lights on to protect a tenant from assault by an unknown assailant. The duty alleged was founded only on the occupier's control of the physical state of the land. The Court left open whether a duty might arise where the complaint concerned control of access or of persons on the land. Lower courts had struggled with the limits of Modbury, particularly in the context of licensed venues and shopping centres.
The Civil Liability Act 2002 (NSW), inserted by the Civil Liability Amendment (Personal Responsibility) Act 2002 (NSW), had already altered the landscape. It enacted a statutory test of breach (s 5B) that emphasised prospective reasonableness and a bifurcated test of causation (s 5D) that separated factual causation from scope of liability and made the "but for" test statutory. Similar legislation was enacted in most Australian jurisdictions. The Liquor Act 1982 (NSW) (now replaced by the Liquor Act 2007 (NSW) with comparable provisions) had long imposed positive obligations on licensees to prevent violent conduct.
Adeels Palace clarified that on licensed premises a duty to take reasonable care to prevent third-party violence can exist. The statutory licensing regime is not used to create the duty by analogy but to ensure that any common-law duty does not cut across the legislative scheme. The decision confirmed that breach must be judged prospectively by reference to s 5B factors and cannot be inferred merely from the fact that harm eventuated. Most importantly, it insisted on rigorous application of the statutory "but for" test of factual causation even where the harm is of the very kind the duty was designed to prevent. In cases of deliberate criminal wrongdoing, especially irrational or determined wrongdoing, plaintiffs face a high evidentiary hurdle. The exceptional-case gateway in s 5D(2) was read narrowly; it does not permit liability on a material-increase-in-risk basis outside established principles such as those in Fairchild.
After the decision, operators of licensed venues must still assess the need for security by reference to the s 5B factors applied prospectively. However, even clear breach will not lead to liability unless the plaintiff can prove that the absence of the relevant precaution was a necessary condition of the particular harm that materialised. The decision therefore narrowed the practical scope of liability for third-party criminal acts on commercial premises despite the existence of a duty.
Key passages with plain-English translation
Paragraph 27: "It is against this statutory background that the question of duty of care must be considered, not for the purpose of developing the common law by analogy with statute law, but to ensure that the imposition of a common law duty of reasonable care of the kind now in question would not run counter to the statutory requirements imposed on licensees in all Australian jurisdictions."
Plain English: We look at the liquor licensing laws not to copy them into the common law but to make sure any duty we recognise does not contradict what Parliament has already required of licensees everywhere in Australia.
Paragraph 40: "Many different matters were relevant to the questions that thus were posed. They included, but were not limited to, such matters as the number of patrons expected to attend the restaurant, the atmosphere that could reasonably be expected to exist during the function, and whether there had been any suggestion of violence at similar events held in comparable circumstances, either at this restaurant or elsewhere. And all of those questions fell to be answered, and the probability of harm and other considerations mentioned in s 5B(2) assessed, prospectively, not with the wisdom of hindsight."
Plain English: To decide if security was needed, you must look forward from before the party started. How many people were coming? What sort of night was likely? Had there been trouble at similar functions? You cannot use the fact that a shooting actually happened to say security was obviously required.
Paragraph 50: "The evidence at trial did not show that the presence of security personnel would have deterred the re-entry of the gunman. That conclusion could have been reached only if it was assumed that the gunman would have acted rationally. But, as was pointed out in Modbury, '[t]he conduct of criminal assailants is not necessarily dictated by reason or prudential considerations'."
Plain English: Security guards might stop a drunk spoiling for a fist fight, but this man had a gun and was out for blood. Criminals do not always behave sensibly. The evidence never proved the guards would have stopped him.
Paragraph 53: "It was not shown to be more probable than not that, but for the absence of security personnel (whether at the door or even on the floor of the restaurant), the shootings would not have taken place. That is, the absence of security personnel at Adeels Palace on the night the plaintiffs were shot was not a necessary condition of their being shot. Because the absence of security personnel was not a necessary condition of the occurrence of the harm to either plaintiff, s 5D(1) was not satisfied."
Plain English: The plaintiffs could not prove that if security had been there the shootings would not have happened. Under the Civil Liability Act that means their case on causation fails.
Paragraph 58: "Even if the presence of security personnel at the door of the restaurant might have deterred or prevented the person who shot the plaintiffs from returning to the restaurant, and even if security personnel on the floor of the restaurant might have been able to intervene in the incident that broke into fighting in time to prevent injury to anyone, neither is reason enough to conclude that this is an 'exceptional case' where responsibility for the harm suffered by the plaintiffs should be imposed on Adeels Palace. To impose that responsibility would not accord with established principles."
Plain English: Just because security might have reduced the chance of injury does not let a court ignore the "but for" test. This is not one of those rare exceptional cases where the law allows liability anyway.
What fact patterns trigger this precedent
The decision is triggered where a plaintiff injured by a deliberate criminal act on licensed premises sues the operator in negligence for failure to provide adequate security. Key elements are: (1) the defendant is the occupier and/or licensee or its corporate operator; (2) the premises are licensed under liquor legislation containing harm-minimisation objects and powers to exclude violent persons; (3) the injury results from an armed or otherwise violent third-party assailant who has entered or re-entered after an earlier altercation; (4) the allegation is that licensed security personnel (crowd controllers under the Security Industry Act) should have been engaged at the door, inside, or both; and (5) the claim is brought after the commencement of the Civil Liability Act or equivalent legislation.
The precedent applies with greatest force where the assailant's conduct is irrational or determined, where prior violent incidents at the venue are few or absent, where the crowd profile is mixed rather than high-risk, and where expert evidence does no more than assert that security "would likely have altered the outcome". It is not limited to restaurants; any licensed venue (hotel, club, function centre) at which alcohol is served and large numbers gather falls within the reasoning. The duty analysis is engaged whenever the operator can control entry and continued presence. The causation analysis is engaged whenever the plaintiff cannot prove on the balance of probabilities that the particular precaution would have prevented the particular assailant from causing the particular harm.
How later courts have treated it
The judgment itself carefully positioned itself within the existing authorities. It distinguished Modbury Triangle on the ground that the duty there was limited to control of the physical state of the land, whereas here the complaint was failure to control access and the conduct of persons on licensed premises ([17]-[19]). It cited March v Stramare to contrast the former "common sense" approach to causation with the statutory bifurcation in s 5D ([44]). It distinguished Chappel v Hart because in that case the "but for" test was satisfied and the debate concerned additional normative considerations; here the "but for" test was not satisfied ([55]). It distinguished Home Office v Dorset Yacht and Stansbie v Troman because in those cases the evidence showed that reasonable care would probably have prevented the injury ([52]). It distinguished Fairchild as involving successive exposures to asbestos and multiple employers, a situation far removed from a single determined gunman on a single night ([58]).
The Court emphasised that its reasoning accorded with established principles and that s 5D(2) is not a general discretion to impose liability whenever a court thinks it fair. Because the decision is a unanimous judgment of the High Court on the construction of the Civil Liability Act (adopted in identical or near-identical form across Australia), later courts are bound to apply the statutory text as interpreted. The prospective nature of the s 5B inquiry, the strictness of the "but for" test, and the narrow reading of "exceptional case" have become the orthodox approach in third-party violence cases on commercial premises.
Still-open questions
The judgment left several matters unresolved. First, it expressly declined to reach a concluded view on breach, noting that the trial judge had not undertaken the s 5B analysis in the manner required. The precise circumstances in which the probability of violence at a licensed venue will require licensed security therefore remain fact-sensitive and will continue to generate dispute.
Second, the content of the "exceptional case" exception in s 5D(2) was not fully mapped. The Court observed that the provision was enacted to deal with cases such as Fairchild but gave no comprehensive guidance on its boundaries. Whether it could ever apply to a single-event intentional tort case, or whether it is limited to cumulative-exposure diseases, remains open.
Third, the interaction between the statutory duty of care analysis and the contractual/implied warranty claim under the Trade Practices Act (now Australian Consumer Law s 60) was left for another day. The Court noted that material contribution might suffice for the statutory warranty but held that even that lower standard was not met on the facts.
Fourth, the Court did not explore the position where security is provided but is alleged to be inadequate in numbers or training, nor did it decide whether a duty might extend to protecting patrons from violence occurring immediately outside the premises after they have been removed.
Finally, the precise evidentiary threshold for proving that security would have prevented re-entry by an armed assailant was not spelled out. The Court rejected both the trial judge's reconstructed inference and the plaintiffs' expert's "altered the chain of events" opinion, but left open what affirmative evidence would be sufficient in a future case.
Gotchas
Most practitioners still assume that if a licensed venue has a foreseeable risk of violence, the mere failure to have licensed security is almost automatically both a breach and a cause of any subsequent injury. Adeels Palace shows this is wrong on two levels. First, breach requires a rigorous prospective s 5B analysis; hindsight that a gunman appeared is irrelevant. Second, and more importantly, causation is now a statutory "necessary condition" test. Even if everyone agrees that security would have been a good idea and might have reduced risk, that is not enough. The plaintiff must prove that this particular assailant would probably have been stopped. In cases of determined, irrational violence the evidentiary burden is extraordinarily high. Many claims that once would have settled for six figures now fail entirely at causation. The "very kind of harm" argument that used to carry the day at common law is, after this decision, largely irrelevant to factual causation. Compliance professionals advising licensed venues should therefore focus on documented risk assessments that address the s 5B factors before each large event rather than assuming that hiring bouncers will automatically buy legal immunity or that their absence will automatically create liability. The decision is a powerful shield for operators but only if the evidentiary record is built prospectively.

FRENCH CJ, GUMMOW, HAYNE, HEYDON AND CRENNAN JJ. The appellant in each appeal (Adeels Palace Pty Ltd - "Adeels Palace") carried on a reception and restaurant business at premises in Punchbowl, New South Wales. The premises were licensed under the Liquor Act 1982 (NSW) ("the Liquor Act"[1]). An "On‑Licence (Restaurant)" licence permitted the service of alcohol on the premises on any day, between midday and 4.00 am on the day following. A condition of the licence limited the seating capacity of the premises to restaurant seating for 295 persons. The local council authorised the use of the premises as a place of public entertainment between midday and 4.00 am on the next day but limited the capacity of the premises to 283 persons. At the times relevant to these matters, a director of Adeels Palace was the licensee.
On 31 December 2002, Adeels Palace was open for business and many came to celebrate the New Year. The restaurant was full. Exactly how many were there was never proved. Admission to the premises, collected at the door, cost $60 per person which included food but not alcoholic drinks. There was a band; there were singers and entertainers; patrons could dance. Seating was at long tables. The bar was open. Waiters brought drinks to the tables.
At about 2.30 am on 1 January 2003, there was a dispute between some women dancing on the dance floor. One accused another of brushing her hand with a lighted cigarette. Words were exchanged. Relatives and friends intervened. Fighting erupted and onlookers joined in. Punches were thrown. Chairs, plates and bottles were thrown. One witness was later to agree that the disruption "got bigger and more ferocious very quickly". As he said, there were "[a] lot of egos out there".
One man involved in the fight was hit in the face, drawing blood. He left the restaurant and returned soon after with a gun. Someone called out "Gun, gun, run away" and Mr Bou Najem (the respondent in the second appeal in this Court) did just that. He ran into the restaurant's kitchen but slipped over. The gunman came in. As Mr Bou Najem tried to get up, the gunman pointed the gun at him. Mr Bou Najem pleaded with him not to shoot, but shoot he did, wounding Mr Bou Najem in the leg.
The gunman left the kitchen and went back into the restaurant itself. There he found the man who had struck him in the face - Mr Moubarak (the respondent in the first appeal). The gunman shot Mr Moubarak in the stomach and then left the premises.
[17]
There was no dispute in these matters that both Mr Bou Najem and Mr Moubarak had suffered serious personal injury. The live issues in the case of each, at trial, on appeal to the Court of Appeal, and in this Court, were, however, whether Adeels Palace owed each a duty of care to prevent harm of the kind suffered, whether that duty had been breached, and whether the breach was a cause of the damage suffered. In Mr Moubarak's case, quantum of damages was a live issue at trial but not on appeal.
In this Court, Adeels Palace submitted that it owed no duty to those attending its premises to prevent criminal conduct by third parties. It submitted that so much is established by this Court's decision in Modbury Triangle Shopping Centre Pty Ltd v Anzil[3]. It submitted further that, if it did owe some relevant duty of care to its patrons, it was not shown that the reasonable response to the risk of violent behaviour at the function would have been to employ licensed security personnel. Finally, it submitted that it was not shown that the want of licensed security personnel was a cause of the shooting of either plaintiff.
Each plaintiff raised further issues in this Court, by notice of contention. Each submitted that he had entered the restaurant under a contract, and that accordingly, by operation of s 74 of the Trade Practices Act 1974 (Cth) ("the Trade Practices Act"), Adeels Palace impliedly warranted that the services it provided would be provided with due care and skill (including, in this case, by provision of suitable security services). As these reasons will later demonstrate, it will not be necessary to consider this contention in any detail. Mr Moubarak further sought to contend (by an amendment of his notice of contention first proposed at the hearing of the appeal to this Court) that causation was established in this case by demonstrating no more than that the failure of Adeels Palace to engage competent security staff "resulted in a material increase in an existing risk of injury to [him] from violent acts of other patrons and so materially contributed to the injuries suffered by him".
In considering each of the issues of duty, breach and causation, it is of the first importance to identify the proper starting point for the relevant inquiry. In this case there are two statutes which require particular consideration: the Civil Liability Act 2002 (NSW) ("the Civil Liability Act") and the Liquor Act. If attention is not directed first to the Civil Liability Act, and then to the Liquor Act, there is serious risk that the inquiries about duty, breach and causation will miscarry.
[18]
The Civil Liability Act is taken to have commenced on 20 March 2002[4]. At the relevant times, s 5A of the Act provided that Pt 1A[5] "applies to any claim for damages for harm resulting from negligence, regardless of whether the claim is brought in tort, in contract, under statute or otherwise". Part 1A of the Act included Div 2, entitled "Duty of care" (ss 5B and 5C), and Div 3, entitled "Causation" (ss 5D and 5E).
Although ss 5B and 5C appear beneath the heading "Duty of care", that heading is apt to mislead. The sections provided:
[19]
(1) A person is not negligent in failing to take precautions against a risk of harm unless:
[20]
(a) the risk was foreseeable (that is, it is a risk of which the person knew or ought to have known), and
[21]
(c) in the circumstances, a reasonable person in the person's position would have taken those precautions.
[22]
(2) In determining whether a reasonable person would have taken precautions against a risk of harm, the court is to consider the following (amongst other relevant things):
[23]
(a) the probability that the harm would occur if care were not taken,
[24]
(c) the burden of taking precautions to avoid the risk of harm,
[25]
(d) the social utility of the activity that creates the risk of harm.
[26]
In proceedings relating to liability for negligence:
[27]
(a) the burden of taking precautions to avoid a risk of harm includes the burden of taking precautions to avoid similar risks of harm for which the person may be responsible, and
[28]
(b) the fact that a risk of harm could have been avoided by doing something in a different way does not of itself give rise to or affect liability for the way in which the thing was done, and
[29]
(c) the subsequent taking of action that would (had the action been taken earlier) have avoided a risk of harm does not of itself give rise to or affect liability in respect of the risk and does not of itself constitute an admission of liability in connection with the risk."
[30]
Both provisions are evidently directed to questions of breach of duty.
[31]
By contrast, Div 3 (ss 5D and 5E) is directed to the subject‑matter described in the heading to the division - Causation. Those sections provided:
[32]
(1) A determination that negligence caused particular harm comprises the following elements:
[33]
(a) that the negligence was a necessary condition of the occurrence of the harm (factual causation), and
[34]
(b) that it is appropriate for the scope of the negligent person's liability to extend to the harm so caused (scope of liability).
[35]
(2) In determining in an exceptional case, in accordance with established principles, whether negligence that cannot be established as a necessary condition of the occurrence of harm should be accepted as establishing factual causation, the court is to consider (amongst other relevant things) whether or not and why responsibility for the harm should be imposed on the negligent party.
[36]
(3) If it is relevant to the determination of factual causation to determine what the person who suffered harm would have done if the negligent person had not been negligent:
[37]
(a) the matter is to be determined subjectively in the light of all relevant circumstances, subject to paragraph (b), and
[38]
(b) any statement made by the person after suffering the harm about what he or she would have done is inadmissible except to the extent (if any) that the statement is against his or her interest.
[39]
(4) For the purpose of determining the scope of liability, the court is to consider (amongst other relevant things) whether or not and why responsibility for the harm should be imposed on the negligent party.
[40]
In determining liability for negligence, the plaintiff always bears the onus of proving, on the balance of probabilities, any fact relevant to the issue of causation."
[41]
These provisions of the Civil Liability Act are central to the questions of breach of duty and causation.
[42]
Consideration of provisions of the Liquor Act is central to the question of duty of care. Why that is so is revealed by the nature of the claims that were made.
Each plaintiff sued Adeels Palace for damages for injury he had suffered on the premises of Adeels Palace. It was not disputed, in either matter, that "[a]t all material times [Adeels Palace] operated [the] licensed premises known as Adeels Palace"[6]. Nor was there any dispute that on 31 December 2002 the business conducted by Adeels Palace was controlled by two men: Mr Simon Bazouni and Mr Fouad Kouzi. Mr Bazouni was licensee.
The central complaint each plaintiff made was that Adeels Palace had not regulated who came onto its premises, who stayed on those premises, and how those who were on the premises conducted themselves towards other patrons. Adeels Palace, as occupier of the premises, could control who came into and who stayed on the premises. But in conducting licensed premises (of which one of its directors was licensee) Adeels Palace was much affected by the duties which the Liquor Act cast on the licensee.
Section 125 of the Liquor Act regulated conduct on licensed premises. Section 125(1)(b) obliged a licensee not to permit on his or her licensed premises "any indecent, violent or quarrelsome conduct". Contravention of the provision was an offence. Section 103(1) of the Liquor Act permitted a licensee, or his or her employee, to "refuse to admit to the licensed premises" or to "turn out, or cause to be turned out, of the licensed premises any person ... who is then ... violent, quarrelsome or disorderly"[7] or "whose presence on the licensed premises renders the licensee liable to a penalty"[8] under the Act. Section 103(3A) permitted the use of "such reasonable degree of force as may be necessary ... to turn a person out" of the premises. Section 103(4) obliged a member of the police force, asked by the licensee or an employee to turn out or assist in turning out a person whom the licensee is entitled to turn out, to comply with the request and provided that the member of the police force may, for that purpose, use such reasonable degree of force as may be necessary.
It is next important to recognise that the particular provisions made in the Liquor Act for controlling violent, quarrelsome or disorderly conduct on licensed premises take their place in a context set by two considerations. First, sale of liquor is controlled because it is well recognised that misuse and abuse of liquor causes harm, including what the Liquor Act refers to as "violent, quarrelsome or disorderly" conduct. Section 2A of the Liquor Act provided:
[43]
"Liquor harm minimisation is a primary object of this Act
[44]
A primary object of this Act is liquor harm minimisation, that is, the minimisation of harm associated with misuse and abuse of liquor (such as harm arising from violence and other anti‑social behaviour). The court, the Board, the Director, the Commissioner of Police and all other persons having functions under this Act are required to have due regard to the need for liquor harm minimisation when exercising functions under this Act. In particular, due regard is to be had to the need for liquor harm minimisation when considering for the purposes of this Act what is or is not in the public interest."
[45]
The second and related point to make is that the duties cast upon those responsible for the service of liquor on licensed premises can be understood as a part of the price that is exacted for the statutory permission granted under the Liquor Act. The permission granted is to do what otherwise the Act forbids[9] - sell liquor - and to do that on premises to which members of the public may resort only in accordance with the conditions on which the licence is granted.
[46]
In considering whether a common law duty of care should be held to exist in these cases, it is important to recognise that the provisions of the Liquor Act that have been mentioned have close analogies in other States and Territories. Though variously expressed, all States and Territories make provision for a licensee of licensed premises to remove from, or prevent the entry to, licensed premises of violent or quarrelsome persons[10]. All State and Territory liquor legislation forbids the sale of liquor without a licence. All State and Territory liquor legislation provides for the licensing of premises on which liquor may be sold and consumed, and not only regulates the sale and service of liquor in such places, but also (as already noted) directly or indirectly regulates the conduct of persons who are on the premises.
It is against this statutory background that the question of duty of care must be considered, not for the purpose of developing the common law by analogy with statute law[11], but to ensure that the imposition of a common law duty of reasonable care of the kind now in question would not run counter to the statutory requirements imposed on licensees in all Australian jurisdictions.
[47]
Contrary to the submissions on behalf of Adeels Palace, this Court's decision in Modbury does not dictate the conclusion that Adeels Palace owed no relevant duty of care to the plaintiffs in the present cases. Like the claims now under consideration, the claim that was made in Modbury was for damages for personal injury suffered as a result of a criminal assault. The injured plaintiff in Modbury had been attacked in a shopping centre car park at night when the lights in the car park were off. He alleged that the shopping centre proprietor was negligent in not leaving the car park lights on. A majority of the Court[12] held that the shopping centre did not owe the plaintiff a duty to take reasonable care to prevent injury to the plaintiff resulting from the criminal behaviour of third persons on the shopping centre's land. It is important to recognise, however, that the duty alleged in Modbury was said to be founded only on the defendant's position as occupier of the land controlling the physical state of the land (there the level of its illumination). What is said in Modbury must be understood as responding to those arguments. No complaint was made[13] that the defendant should have controlled, but did not control, access by the assailants to the land it occupied.
It is, of course, important to recognise that the decision in Modbury forms part of a line of cases in which consideration has been given to whether and when one person owes another a duty to take reasonable care to control the conduct of a third person[14]. And the fact that the conduct in question is criminal conduct is of great importance in deciding not only what, if any, duty is owed to prevent its commission, but also questions of breach and causation.
Several considerations set the present case apart from Modbury and point to the conclusion that Adeels Palace owed each plaintiff a relevant duty of care. First, the complaint that was made in these cases was that the occupier of premises failed to control access to, or continued presence on, its premises[15]. Secondly, the premises concerned were licensed premises where liquor was sold. They were, therefore, premises where it is and was well recognised that care must be taken lest, through misuse and abuse of liquor, "harm [arise] from violence and other anti‑social behaviour"[16]. And thirdly, the particular duty said to have rested on the occupier of the premises (who was the operator of the business that was conducted on the premises) is a duty to take reasonable care to prevent or hinder the occurrence of events which, under the Liquor Act, the licensee was bound to prevent occurring - violent, quarrelsome or disorderly conduct. (And although variously expressed in the legislation of other Australian jurisdictions, the evident scheme of all liquor licensing laws in Australia is to minimise anti‑social conduct both on and off licensed premises associated with consumption of alcohol.)
[48]
The question of breach of duty must be considered by reference to the relevant provisions of the Civil Liability Act - in particular s 5B.
It may be accepted, for the purposes of argument, that there was a risk, of which Adeels Palace knew or ought to have known[18], that there would be violent, quarrelsome or disorderly conduct in the restaurant. It may also be accepted that this risk "was not insignificant"[19]. The question then becomes whether a reasonable person in the position of Adeels Palace would have taken the precautions that the plaintiffs alleged should have been taken[20]. Those precautions were the provision of licensed[21] security personnel who would act as crowd controllers or bouncers.
Just how many security personnel the plaintiffs alleged should have been provided was not always made clear in argument. The plaintiffs pleaded their cases on the basis that there should have been not only security personnel controlling the entrance to the premises but also sufficient security personnel to intervene in any dispute that broke out within the restaurant. Because the restaurant was on the second floor of a building it seems to have been accepted that to supervise what was happening inside the restaurant would have required personnel who were different from those who controlled access to the premises. Some evidence led at trial suggested that as many as six or eight persons would have been necessary to supervise both the interior of, and the entrance to, the restaurant.
Whether any, and how many, security personnel should have been provided to satisfy the duty of Adeels Palace to take reasonable care depended upon the considerations identified in s 5B(2) of the Civil Liability Act: the probability that the harm would occur, the likely seriousness of the harm, the burden of taking precautions to avoid the risk, and the social utility of the activity that created the risk. No doubt the chief focus of those inquiries in these cases would fall upon the first three of those considerations.
Many different matters were relevant to the questions that thus were posed. They included, but were not limited to, such matters as the number of patrons expected to attend the restaurant, the atmosphere that could reasonably be expected to exist during the function, and whether there had been any suggestion of violence at similar events held in comparable circumstances, either at this restaurant or elsewhere. And all of those questions fell to be answered, and the probability of harm and other considerations mentioned in s 5B(2) assessed, prospectively[22], not with the wisdom of hindsight. That is, they were to be assessed before the function began, not by reference to what occurred that night.
[49]
The first point to make about the question of causation is that, in these cases, it is governed by the Civil Liability Act.
Section 5D(1) of that Act divides the determination of whether negligence caused particular harm into two elements: factual causation and scope of liability.
Dividing the issue of causation in this way expresses the relevant questions in a way that may differ from what was said by Mason CJ, in March v Stramare (E & M H) Pty Ltd[25], to be the common law's approach to causation. The references[26] in March v Stramare to causation being "ultimately a matter of common sense" were evidently intended to disapprove the proposition "that value judgment has, or should have, no part to play in resolving causation as an issue of fact". By contrast, s 5D(1) treats factual causation and scope of liability as separate and distinct issues.
It is not necessary to examine whether or to what extent the approach to causation described in March v Stramare might lead to a conclusion about factual causation different from the conclusion that should be reached by applying s 5D(1). It is sufficient to observe that, in cases where the Civil Liability Act or equivalent statutes are engaged, it is the applicable statutory provision that must be applied.
Next it is necessary to observe that the first of the two elements identified in s 5D(1) (factual causation) is determined by the "but for" test: but for the negligent act or omission, would the harm have occurred?
In the Court of Appeal, Giles JA, who gave the principal reasons, pointed out[27], correctly, that the reasoning of the trial judge on the question of causation was "not fully articulated". The reasoning was reconstructed[28] by Giles JA in the following terms:
[50]
"From the evidence, security staff would have been aware of a significant fracas on the dance floor. Even if [the gunman] had not been identified at the time as the man who had got into a fight with Mr Moubarak, the presence of blood on his face would have caused the security staff at the street entrance, particularly with knowledge of the fracas, to deny him entry, or at least to require that he submit to search as a condition of being permitted to enter. On the balance of probabilities, security staff at the street entrance would have deterred or prevented [the gunman's] re‑entry, and he therefore would not have shot Mr Moubarak and Mr Bou Najem."
[51]
Security personnel may have been able to deter or prevent re‑entry by the drunk or the obstreperous would‑be patron willing to throw a punch. There was, however, no basis in the evidence for concluding that security staff at the entrance to the restaurant would have deterred or prevented the re‑entry to the premises of a man armed with a gun when later events showed he was ready and willing to use the weapon on persons unconnected with his evident desire for revenge.
The evidence at trial did not show that the presence of security personnel would have deterred the re‑entry of the gunman. That conclusion could have been reached only if it was assumed that the gunman would have acted rationally. But, as was pointed out in Modbury[29], "[t]he conduct of criminal assailants is not necessarily dictated by reason or prudential considerations". The gunman's conduct at the restaurant on this night was dictated neither by reason nor by prudential considerations. He shot the man who had struck him during the mêlée that broke out after the confrontation on the dance floor. And before shooting that man, the gunman had shot a man who had done nothing to him and who, defenceless, begged for mercy.
Nor did the evidence show that security personnel could or would have prevented re‑entry by the gunman: a determined person armed with a gun and irrationally bent on revenge. The evidence given at trial by the plaintiffs' expert security consultant did not go beyond the assertion that a security person confronting the gunman at the entrance to the restaurant "would have at least altered the chain of events and thereby likely altered the outcome". The security consultant called on behalf of Adeels Palace emphasised that the overriding principle which should govern the conduct of security personnel confronted by a gunman is "safety for all parties" and that "once a determined gunman is targeting a victim or victims there [is] no guaranteed safe or effective option".
Recognising that changing any of the circumstances in which the shootings occurred might have made a difference does not prove factual causation. Providing security at the entrance of the restaurant might have delayed the gunman's entry; it might have meant that, if Mr Bou Najem was a random victim, as seemed to be the case, someone else might have been shot and not him. But neither plaintiff proved factual causation by pointing to possibilities that might have eventuated if circumstances had been different.
[52]
As noted earlier in these reasons, each plaintiff sought to support the orders made in his favour in the Court of Appeal by contending that s 74 of the Trade Practices Act was engaged. Even if that were so, each plaintiff could recover damages for breach of such an implied warranty only if he established at least that breach of the warranty was a cause of (in the sense of materially contributed to) his loss[40]. Whether more than material contribution to loss must be established to make good a claim for breach of an implied warranty need not be considered. For the reasons given earlier, a "but for" causal connection between absence of security and injury to either plaintiff was not established in these cases. It was not shown that absence of security materially contributed to either plaintiff being injured. The contention that the judgment below is to be supported by reference to s 74 of the Trade Practices Act should be rejected.
[53]
Each appeal should be allowed with costs. In each case the orders of the Court of Appeal of the Supreme Court of New South Wales entered on 24 March 2009 should be set aside and in their place there should be orders that the appeal to that Court is allowed with costs, the judgment of the District Court of New South Wales set aside and in its place there be judgment for the defendant with costs.

Liquor licensing and corporate records tendered in evidence at trial appear to suggest that a company called Adeel's Restaurant Pty Ltd was the owner of the business at the relevant time but in the light of the way in which the trial was conducted this suggestion need not be examined further.

Appeals allowed with costs; orders of the Court of Appeal set aside; in lieu thereof, appeals to that Court allowed with costs and judgment entered for the defendant with costs in each matter.
The two men who were shot, Mr Bou Najem and Mr Moubarak, each brought proceedings in the District Court of New South Wales against Adeels Palace claiming damages for personal injury. Each alleged that they had suffered injury as a result of Adeels Palace's negligence in not providing any or any sufficient security during the function on New Year's Eve.
In the District Court, the two actions were heard together, and each plaintiff obtained judgment for damages. Adeels Palace appealed to the Court of Appeal of New South Wales and that Court (Beazley, Giles and Campbell JJA) dismissed[2] each appeal. By special leave, Adeels Palace appeals to this Court. Each appeal should be allowed. Consequential orders should be made entering judgment in each proceeding for Adeels Palace.
In the circumstances reasonably to be contemplated before the restaurant opened for business on 31 December 2002 as likely to prevail on that night, Adeels Palace owed each plaintiff a duty to take reasonable care to prevent injury to patrons from the violent, quarrelsome or disorderly conduct of other persons. The duty is consistent with the duty imposed by statute upon the licensee and which was a duty enforceable by criminal processes. No question arises of translating a statutory power given to a statutory body into the common law "ought"[17]. The duty is not absolute; it is a duty to take reasonable care. It is not a duty incapable of performance. It is a duty the performance of which is supported by the provision of statutory power to prevent entry to premises and to remove persons from the premises, if needs be by using reasonable force. Although it is a duty directed to controlling the conduct of others (for the avoidance of injury to other patrons) it is a duty to take reasonable care in the conduct of activities on licensed premises, particularly with regard to allowing persons to enter or remain on those premises.
The evidence led in these cases included evidence of the opinions of persons who described themselves as security consultants. The trial judge understood the evidence of the experts called by the plaintiffs and by Adeels Palace as accepting that there had been a "need for 'access control' as the 'front line of defence' ... having the purpose of discouraging at least, if not preventing, the return of unruly or troublesome patrons who [had] left the premises". Whether or to what extent this opinion of the experts was based on their consideration of what had happened on this occasion (an irrelevant inquiry), as opposed to the probability of violence if "access control" were not provided[23], was not expressly considered by the trial judge.
No finding was made below that there should have been security personnel supervising conduct in the restaurant. Both the trial judge and the Court of Appeal proceeded on the footing that it was sufficient to find that the failure to provide security personnel who would control access to the restaurant was a breach of the duty of care owed by Adeels Palace. That is, both the trial judge and the Court of Appeal concluded that the failure of Adeels Palace to provide licensed personnel to act as crowd controllers or bouncers at the door of the premises (in addition to whomever Adeels Palace used to take the cost of admission from patrons at the door) was a breach of the duty of care owed by Adeels Palace to its patrons.
Having regard to the Civil Liability Act, this conclusion could be reached only if the probability of "unruly or troublesome patrons who [had] left the premises" returning to do violence to other patrons, or the probability of other persons likely to do violence to patrons seeking to gain entry to the premises, was such that a reasonable person in the position of Adeels Palace would have employed security personnel to control access to the restaurant.
But why a reasonable person would have taken that step was never clearly articulated in argument or in the reasoning of the trial judge. Considered in isolation, the numbers attending the restaurant, and the type of customers (spread over a range of ages, with some in family or friendship groups extending over several generations), did not demonstrate a need for provision of security personnel controlling access to the restaurant. And despite the plaintiffs' attempt to prove at trial that the venue had a history of violent incidents, there appears to have been nothing in that history (which went no further than some reports of threatening conduct by passers‑by outside the restaurant premises) which would have warranted the conclusion that there was the probability of violence erupting in or about the restaurant. No argument to that effect was advanced orally in this Court.
Reference was made in argument in this Court on behalf of Mr Bou Najem to the possibility that security personnel supervising the floor of the restaurant may have been able to intervene in the dispute on the dance floor and prevent the rapid descent into general violence that followed. To do that would have required several more security personnel than the small number it was suggested should have been controlling access to the restaurant.
The argument necessarily asserted that licensed security personnel were the appropriate response to this risk. That is, the argument was that any exchange of words between patrons at this function would require an immediate and decisive response by persons having what might be called the "presence" or "physical authority" of bouncers or crowd controllers.
Of course there is always a risk that there will be some altercation between patrons at almost any kind of event. And the risk of that happening is higher if the patrons are consuming alcohol. But unless the risk to be foreseen was a risk of a kind that called for, as a matter of reasonable precaution, the presence or physical authority of bouncers or crowd controllers to deal with it safely, failure to provide security of that kind would not be a breach of the relevant duty of care. As noted earlier, there was no finding at trial or in the Court of Appeal that a risk of that kind should have been foreseen.
The absence of consideration at trial of the matters prescribed by s 5B of the Civil Liability Act may have been reason enough to conclude that the question of breach of duty was not determined properly by the trial judge. It is, however, not profitable to examine that issue further.
It is not profitable to do that because resolution of the issue of breach would necessarily depend only upon the evidence that was led at trial. The points to be made that are of general application are first, that whether a reasonable person would have taken precautions against a risk is to be determined prospectively, and second, that the answer given in any particular case turns on the facts of that case as they are proved in evidence. It follows from the second of these considerations that deciding the question of breach in these cases would not establish any rule about when or whether security personnel should be engaged by the operators of licensed premises. It is not useful[24] in these circumstances for this Court to form a conclusion about whether breach was proved in these cases. In particular, it is not necessary to examine the evidence that was led at trial to determine whether the finding of breach could be supported. Instead, it is desirable to consider the question of causation. Examination of that issue reveals that the negligence found against Adeels Palace was not shown to have been a cause of the injuries suffered by the plaintiffs.
Nor was "but for" causation established in these cases by observing that the relevant duty was to take reasonable care to prevent injury to patrons from the violent, quarrelsome or disorderly conduct of other persons. That is, the question of factual causation was not answered in these cases by pointing out that the relevant duty of care was to take reasonable steps to prevent violent assault, that each plaintiff was the victim of a violent assault, and that the damage sustained by the plaintiffs was "the very kind of thing" which the relevant duty obliged Adeels Palace to take reasonable steps to prevent[30]. That observation may bear upon questions about scope of liability[31]. Describing the injury as "the very kind of thing" which was the subject of the duty must not be permitted to obscure the need to prove factual causation. Unlike Home Office v Dorset Yacht Co Ltd[32] and Stansbie v Troman[33], these are not cases where the evidence demonstrated that the taking of reasonable care would probably have prevented the occurrence of injury to the plaintiffs.
Counsel for the plaintiffs, in this Court, relied upon passages in Chappel v Hart[34]. But in that case the majority proceeded on the basis that but for the failure to warn the event would not have happened; the question then was whether certain additional factors, combined with the satisfaction of the "but for" test, were sufficient to establish causation[35].
In the present case, in contrast, the "but for" test of factual causation was not established. It was not shown to be more probable than not that, but for the absence of security personnel (whether at the door or even on the floor of the restaurant), the shootings would not have taken place. That is, the absence of security personnel at Adeels Palace on the night the plaintiffs were shot was not a necessary condition of their being shot. Because the absence of security personnel was not a necessary condition of the occurrence of the harm to either plaintiff, s 5D(1) was not satisfied. Did s 5D(2) apply?
Section 5D(2) makes provision for what it describes as "an exceptional case". But the Act does not expressly give content to the phrase "an exceptional case". All that is plain is that it is a case where negligence cannot be established as a necessary condition of the harm; the "but for" test of causation is not met. In such a case the court is commanded "to consider (amongst other relevant things) whether or not and why responsibility for the harm should be imposed on the negligent party". But beyond the statement that this is to be done "in accordance with established principles", the provision offers no further guidance about how the task is to be performed. Whether, or when, s 5D(2) is engaged must depend, then, upon whether and to what extent "established principles" countenance departure from the "but for" test of causation.
At once it must be recognised that the legal concept of causation differs from philosophical and scientific notions of causation[36]. It must also be recognised that before the Civil Liability Act and equivalent provisions were enacted, it had been recognised[37] that the "but for" test was not always a sufficient test of causation. But as s 5D(1) shows, the "but for" test is now to be (and has hitherto been seen to be) a necessary test of causation in all but the undefined group of exceptional cases contemplated by s 5D(2).
Even if the presence of security personnel at the door of the restaurant might have deterred or prevented the person who shot the plaintiffs from returning to the restaurant, and even if security personnel on the floor of the restaurant might have been able to intervene in the incident that broke into fighting in time to prevent injury to anyone, neither is reason enough to conclude that this is an "exceptional case" where responsibility for the harm suffered by the plaintiffs should be imposed on Adeels Palace. To impose that responsibility would not accord with established principles.
It may be that s 5D(2) was enacted to deal with cases exemplified by the House of Lords decision in Fairchild v Glenhaven Funeral Services Ltd[38] where plaintiffs suffering from mesothelioma had been exposed to asbestos in successive employments. Whether or how s 5D(2) would be engaged in such a case need not be decided now. The present cases are very different. No analogy can be drawn with cases like Fairchild. Rather, it would be contrary to established principles to hold Adeels Palace responsible in negligence if not providing security was not a necessary condition of the occurrence of the harm but providing security might have deterred or prevented its occurrence, or might have resulted in harm being suffered by someone other than, or in addition to, the plaintiffs. As in Modbury[39], the event which caused the plaintiffs' injuries was deliberate criminal wrongdoing, and the wrongdoing occurred despite society devoting its resources to deterring and preventing it through the work of police forces and the punishment of those offenders who are caught. That being so, it should not be accepted that negligence which was not a necessary condition of the injury that resulted from a third person's criminal wrongdoing was a cause of that injury. Accordingly, the submission that the plaintiffs' injuries in these cases were caused by the failure of Adeels Palace to take steps that might have made their occurrence less likely, should be rejected.
