Plain English Summary
Peter Bini robbed a BP service station at gunpoint, taking about $502. He later put the cash in his pockets and kept it. His defence that he was mentally incompetent at the time failed. The court then decided whether he had the required criminal intention – specifically, whether he meant to keep the money permanently. The court found he did, because he took the money, kept it, and never showed any intention of giving it back. He was therefore found guilty of armed robbery.

What happened
On 20 February 2001, Peter Bini drove a ute to a BP service station at Munno Para, South Australia. After filling his vehicle with petrol, he pulled a dark woollen beanie over his head, entered the station brandishing a rifle, pointed it at the console operator, Felicity Mellor, and demanded all the money. The operator handed him the entire till, which contained about $502. Bini took it, walked out, and drove away at high speed. Shortly after leaving, he removed the cash from the till and transferred it into his wallet and pockets. The till itself was later found empty in his ute.
Police monitoring the vehicle realised it was the one involved in the robbery and followed it northward. Bini's vehicle eventually broke down at an intersection in Gawler South, emitting a large cloud of smoke. Bini alighted, stood by the vehicle, then retrieved the rifle and confronted the two police constables, holding the rifle at a 45-degree angle pointing forward. He was arrested without further incident. At least $500 in cash was found in his wallet and pockets.
Bini was charged with armed robbery. He pleaded not guilty and raised a defence of mental incompetence under Part 8A of the Criminal Law Consolidation Act 1935 (SA). He elected for trial by judge alone. Pursuant to the statutory framework, the judge first separated the question of mental competence from the remainder of the trial and proceeded with the objective elements of the offence. On 5 October 2001, Judge Muecke found the objective elements proved beyond reasonable doubt. He then conducted a trial on mental competence, hearing extensive medical evidence on Bini's borderline personality disorder and other matters. On 1 April 2003, the judge published reasons concluding that the defence had not established on the balance of probabilities that Bini was mentally incompetent to commit the offence; the presumption of mental competence was not displaced. The trial therefore proceeded in the normal way on 27 May 2003 to determine the subjective elements – the mental state or mens rea required for armed robbery. No further evidence was adduced; both parties relied on the evidence already before the court. The key question at this stage was whether the prosecution could prove beyond reasonable doubt that Bini had the requisite intention to permanently deprive the owner of the money taken.
Why the court decided this way
The judge accepted the submission of counsel for the Director of Public Prosecutions that there were two subjective elements: an intention to use the firearm to facilitate the taking of the money, and an intention to appropriate the money to himself (the second element being the crucial one at issue). Defence counsel contended that the proper test was narrower: the prosecution must prove beyond reasonable doubt an intention at the time of taking to permanently deprive the owner of the money. After considering Foster v The Queen [1967] HCA 8; (1967) 118 CLR 117, the judge concluded that the two formulations are essentially the same. Barwick CJ in Foster stated that larceny requires an intention to assume ownership, to deprive permanently, or to deprive of property – all expressions of the same element. An intention to deprive the true owner of possession for a limited time is insufficient. Applying that test, the judge examined the factual findings.
In supplementary findings at [17], the judge set out the key circumstances. Bini had very little money left when he left the hotel at Tanunda before the robbery; his purpose in calling a person for money was to continue drinking. After the robbery, he immediately transferred the cash from the till into his pockets. He drove north, away from the scene, and when his vehicle broke down, he did not attempt to return the money. His own evidence did not suggest any intention to return it. The judge specifically found that it was not a reasonable possibility that Bini intended to return the money. The judge also found that the robbery was motivated partly by stress related to his borderline personality disorder, but that did not negate the requisite intention. At [18]–[20], the judge declared himself satisfied beyond reasonable doubt that Bini intended to permanently deprive the owner of the money, that he had an intention to assume ownership, and that there was no intention to later restore the money. Because the prosecution had proved the subjective elements, the judge concluded that Bini possessed the necessary mental state for armed robbery.
Before and after state of the law
Before this judgment, the law in South Australia on the mental element for larceny (and thus for robbery, which includes larceny aggravated by the use or threat of violence) was settled by Foster v The Queen. That case confirmed the common law requirement of an intention to permanently deprive the true owner of the property. The decision in R v Bini does not change the substantive law but illustrates its application in the context of the two-stage trial procedure under Part 8A.
The judgment clarifies that even where a mental incompetence defence has been raised and rejected, the court must still consider the subjective elements separately. The trial on mental competence under s 269GB considers the accused's capacity to form the relevant mental state, while the subsequent normal trial on subjective elements considers whether the prosecution can prove that the accused actually had the relevant mental state. The judge in Bini applied the same test from Foster to the latter question, confirming that the mental state required is an intention to permanently deprive, not merely an intention to appropriate for one's own purposes (a formulation suggested by the prosecution that was not adopted).
After this judgment, practitioners have clear guidance that in a judge-alone armed robbery trial following a failed mental incompetence plea, the judge must use the standard Foster test for intention. The judgment also reinforces that the existence of a mental disorder, even if not amounting to legal incompetence, may explain the commission of the offence but does not automatically negate the requisite mens rea.
Key passages with plain-English translation
Paragraph [13] – The test from Foster v The Queen (quoted from Barwick CJ):
Original: "Larceny ... involved an intention on the part of the applicant to assume ownership of the gun, to deprive Baker permanently of it, to deprive him of the property in it. I use these three expressions, which are several ways of establishing the same essential element of larceny, namely, the intention to appropriate the goods to himself."
Translation: To be guilty of stealing, a person must have intended to treat the item as their own – to permanently take it away from the true owner. Whether you say "intend to assume ownership", "intend to permanently deprive", or "intend to take possession as if you own it", they all mean the same thing.
Paragraph [16] – The judge's acceptance of the permanent deprivation test:
Original: "I shall proceed on the basis that I must be satisfied beyond reasonable doubt that the accused intended at the time of taking the money to deprive the owner of it permanently. I do not consider that Foster's case in some way widens this element or ingredient of the offence of larceny."
Translation: The judge decided to apply the stricter test – requiring proof of an intention to permanently deprive – rather than a broader test suggested by the prosecution. He concluded that Foster does not expand the requirement.
Paragraph [17] (finding 6) – The crucial factual finding:
Original: "I am satisfied beyond reasonable doubt that when he took the money from the service station he intended to keep it for himself. I do not consider that it is a reasonable possibility that he intended to return it to the owner. His evidence was not to that effect."
Translation: The evidence proved that Bini meant to keep the money when he took it. There is no credible suggestion that he planned to give it back.
Paragraph [18] – The conclusion on intention:
Original: "I am satisfied beyond reasonable doubt that when the accused demanded and took money ... he intended to deprive the owner of that money permanently."
Translation: The prosecution has proved the case. Bini had the required criminal intention.
What fact patterns trigger this precedent
This precedent is directly applicable in cases where an accused person is charged with armed robbery (or larceny/robbery) and:
The accused has raised a defence of mental incompetence and that defence has been determined adversely.
The trial proceeds in the normal way to determine subjective elements.
The court must decide whether the prosecution has proved an intention to permanently deprive the owner of the property taken.
The key triggering factors from Bini are:
The accused took property from the victim immediately and did not return it.
The accused transferred the property away from the scene or concealed it.
The accused used the property or kept it for his own benefit.
There was no evidence (from the accused or otherwise) that he intended to return the property.
The accused fled the scene and attempted to avoid apprehension.
Even where the accused has a diagnosed mental disorder (like borderline personality disorder in Bini), that alone does not prevent a finding of intention, provided the disorder does not amount to legal incompetence.
The case also provides a template for the two-stage trial procedure under Part 8A: first, a judge alone determines objective elements and then mental competence; second, if competence is established, the judge proceeds to determine subjective elements on the same evidence (unless further evidence is adduced). Practitioners should note that findings from the mental competence trial – including medical evidence about the accused's state of mind – can be used in the subjective elements trial, subject to appropriate directions.
How later courts have treated it
R v Bini (No 2) is a District Court decision and is not binding on higher courts, but it has been cited in subsequent South Australian decisions for its explanation of the post-mental incompetence trial procedure and the application of Foster. It is frequently referenced in judgments dealing with s 269GB of the Criminal Law Consolidation Act, especially in the context of judge-alone trials where mental impairment is raised. It has not been overruled or disapproved. Later cases have consistently applied the Foster test as confirmed in Bini. The decision also stands as an example of how a court should separate the mandatory criteria for mental incompetence (capacity to know the nature and quality of the act, capacity to know it was wrong, capacity to control actions) from the ordinary mens rea enquiry. In other Australian jurisdictions with similar statutory schemes (e.g. Victoria, New South Wales), the reasoning on the interplay between mental impairment defences and subjective elements has been considered, though the specific procedural framework differs.
Still-open questions
Interaction between mental incompetence and subjective elements:Bini confirms that a finding of mental competence does not automatically prove the subjective elements. But what if the accused's mental disorder is so severe that it negates the specific intent required (e.g., an inability to form the requisite intention to permanently deprive) but does not meet the higher threshold of incompetence under Part 8A? The judgment does not explore this borderline scenario, leaving open whether expert evidence on capacity can be used at the subjective-elements stage to argue that the accused could not have formed the necessary intention, even though he was not legally incompetent.
The scope of "permanent deprivation":Bini reaffirms the classic test. But modern cases involving conditional taking (e.g., taking property as security for a debt, or taking and then abandoning) continue to be litigated. The judgment does not address the full spectrum of what constitutes permanent deprivation in circumstances where the property is later recovered but the accused had no intention of returning it at the time of taking.
Role of psychiatric evidence on intention: The judge in Bini relied on psychiatric evidence to explain motivation but held it did not negate intention. Later courts might need to consider whether certain types of mental illness (e.g., severe delusional states that do not meet incompetence standards) can be relevant to the formation of specific intent, and how that evidence should be weighed.
Jury directions after a judge-alone trial on mental competence:Bini was a judge-alone trial. If a jury were to be empanelled after a mental incompetence finding, the jury would need careful directions about the prior findings on objective elements and the burden of proof on subjective elements. The Bini procedure provides a model, but the practical issues of jury management in such cases remain open.
Appeals from split trials: Given the two-stage procedure, the interaction of appeal rights from each stage is not directly addressed. If a defendant is convicted after the subjective elements stage, can he appeal the mental competence finding as part of that appeal? The judgment does not resolve timing or finality issues under the statutory regime.
The accused is charged with armed robbery. The particulars of that offence are that he, on 20 February 2001 at Munno Para, being armed with an offensive weapon, namely a firearm, robbed Felicity Jane Mellor of money in the amount of about $502.00.
[4]
The matter was ultimately listed for trial to commence on 3 October 2001. On that day the accused pleaded not guilty. I was informed that he raised a defence of mental incompetence pursuant to Division 2 (Mental Competence to Commit Offences) of Part 8A (Mental Impairment) of the Criminal Law Consolidation Act 1935 (SA) ("the Act"). The accused elected for trial by judge alone.
[5]
I separated the question of the accused's mental competence to commit the offence from the remainder of the trial. I decided to proceed first with the trial of the objective elements of the offence. After receiving and hearing evidence I indicated on 5 October 2001 that I was satisfied that the objective elements of the offence of armed robbery against the accused were established beyond reasonable doubt. I excluded from consideration on that question any question as to whether the accused's conduct was defensible. I recorded a finding that the objective elements of the offence are established.
[6]
I then proceeded in accordance with s.269GB of the Act. I heard relevant evidence and representations by the prosecution and the defence on the question of the accused's mental competence to commit the offence. That investigation commenced on 4 November 2002. Counsel for the accused and the DPP agreed that in that investigation I should have before me the evidence that was before me when I considered whether the objective elements of the offence were established. That investigation concluded on 6 February 2003.
[7]
At the conclusion of the trial of the accused's mental competence I had to decide whether it had been established, on the balance of probabilities, that the accused was at the time of the alleged offence mentally incompetent to commit the offence.
[8]
On 1 April 2003 I published reasons for deciding that it had not been established, on the balance of probabilities, that the accused was at the time of the alleged armed robbery mentally incompetent to commit it ([2003] SADC 35). I recorded a finding that the presumption of mental competence had not been displaced. I indicated that I would proceed with the trial in the normal way (s269GB(3)(b) of the Act).
[9]
I did so on 27 May 2003. On that day neither counsel for the DPP nor for the accused sought to or did put further evidence before me.
[10]
I have already referred to the fact that on 5 October 2001 I recorded a finding that the objective elements of the offence the accused is alleged to have committed on 20 February 2001 are established. An "objective element" of an offence means an element of an offence that is not a subjective element. A "subjective element" of an offence means voluntariness, intention, knowledge or some other mental state that is an element of the offence (s.269A(1) of the Act).
[11]
On 27 May 2003 counsel for the DPP submitted that proceeding with the trial in the normal way involved a consideration by me of the subjective elements of the offence alleged against the accused, or in other words the mental elements or the requisite mens rea of the offence. He submitted that as to these the onus reverts to the prosecution. He submitted that it is incumbent on the prosecution to satisfy me that the two subjective or mental elements of the offence can be inferred beyond reasonable doubt, in the sense that proof of these elements are the only reasonable and rational conclusions that are open on the evidence I had heard.
[12]
Counsel for the accused did not suggest that proceeding with the trial "in the normal way" involved something other than that which was submitted by counsel for the DPP.
[13]
I proceeded on that basis and I heard submissions from both counsel. Both counsel referred to and relied on evidence I had previously heard in the earlier investigations or trials that had been conducted before me. They both referred in particular to the evidence that I heard during the trial of the accused's mental competence to commit the offence. I neither heard nor received any further evidence.
[14]
Counsel for the DPP submitted that there are two subjective elements of the offence the accused is alleged to have committed. First, an intention by him to use the firearm to facilitate the asportation of the money from the BP Service Station at Munno Para. Secondly, a co-existing intention to appropriate the money to himself for his own purposes. Counsel for the accused made no submissions as to whether or not the accused had an intention to use the firearm to facilitate the asportation of the money. He did submit, however, that I should not be satisfied beyond reasonable doubt of the second of the subjective elements referred to by counsel for the DPP. Furthermore, he submitted that the proper test was a narrower one than that submitted by counsel for the DPP. He submitted that I must be satisfied beyond reasonable doubt that at the time of taking the money the accused intended to deprive the owner of it permanently. He submitted that that was a stricter test than one requiring me to be satisfied beyond reasonable doubt that the accused had an intention at the time of taking the money to appropriate it to himself for his own purposes.
[15]
In support of his submission counsel for the DPP referred to Foster v The Queen [1967] HCA 8; (1967) 118 CLR 117. In that case Barwick CJ said (at p. 121):
[16]
Larceny under the Crimes Ordinance 1951 (A.C.T.) as under the Crimes Act, 1900 (N.S.W.) being undefined, is as under the common law. It involved an intention on the part of the applicant to assume ownership of the gun, to deprive Baker permanently of it, to deprive him of the property in it. I use these three expressions, which are several ways of establishing the same essential element of larceny, namely, the intention to appropriate the goods to himself. To intend to deprive the true owner permanently of the possession of the goods is one form of the requisite intention. An intention to deprive him of his property in the goods is another, that is, an intention to appropriate the goods as distinct from merely to assume possession of them. Section 118 of the Ordinance does not deny the necessity for an intention in one of these forms to accompany the taking. It deals with the case of an accused who has appropriated the property and not of an accused who has only assumed possession of it. It merely ensures that the consequence of forming or having that intention is not defeated by an intention eventually to restore the property to the true owner. Thus, if the intention is to deprive the true owner of possession for a limited time, larceny is not made out. But if the intention of the taker is to exercise ownership of the goods, to deal with them as his own, an intention later to restore the property in the goods will not prevent the original taking being larcenous.
[17]
Counsel for the DPP also relied on authorities referred to at pages 43-46 of Weinberg and Williams, The Australian Law of Theft, 1977, 1st edition.
[18]
Counsel for the accused submitted that neither Foster's case nor the authorities referred to in the text are authority for widening the intention in larceny beyond an intention at the time of the taking of some property to deprive the owner of it permanently. He submitted that an intention to deprive the true owner of the possession of property permanently is the test I must apply in this case.
[19]
I shall proceed on the basis that I must be satisfied beyond reasonable doubt that the accused intended at the time of taking the money to deprive the owner of it permanently. I do not consider that Foster's case in some way widens this element or ingredient of the offence of larceny. In the passage cited above Barwick CJ indicated that different expressions were used for the same essential element of larceny.
[20]
I now set out certain findings which are supplementary to those facts and circumstances to which I referred in my conclusions to my reasons of 1 April 2003.
[21]
1. I am satisfied that at about 4.00 pm on 20 February 2003 the accused stopped his ute in front of a petrol pump at the BP Service Station just before he entered the service station. He filled his vehicle with $49 worth of Super Green. The day was hot and the accused was wearing a dark coloured woollen beanie on his head whilst he filled up his vehicle with petrol. He got into his car and drove right up to the front of the BP Service Station in front of the door. His ute was blocking the door. He pulled the beanie down over his head and entered the service station waving his rifle which was in his right hand. He pointed the rifle directly at the console operator and said "give me the money, everything, everything". She opened the till and handed the whole of the till to the accused. The accused took it, turned around and walked quickly out of the service station. He drove off extremely fast in his ute heading in a southerly direction down Main North Road.
[22]
2. I am satisfied beyond reasonable doubt that at some time between 4.00 pm and 4.30 pm on 20 February 2001 the accused emptied all the money from the till he had taken from the service station into his pockets. He put the majority of the money into his wallet which he put into his pocket. I am satisfied beyond reasonable doubt that at least $500 in cash that was found in the accused's wallet and pockets was the contents of the till he had taken from the service station. I am so satisfied because I am satisfied that the till was empty when found in his ute and that the accused had very little money left when he left the hotel at Tanunda to start his drive south towards Adelaide. The purpose of his call to 'Lynne Russell was to obtain money to continue drinking.
[23]
3. I am satisfied that police followed the accused as he drove his ute north towards Tanunda. Police dropped back to a safer distance from the rear of the vehicle when they realised it was the vehicle that was wanted in relation to the hold-up at the service station. They noticed that the vehicle was blowing a large amount of smoke from its exhaust. As they followed the vehicle the smoke became thicker. They did not attempt to stop the vehicle as it proceeded north at a speed of about 80 kpm. At about 4.45 pm the accused's ute stopped at a stop sign at the intersection of First and Seventh Streets, Gawler South. It was facing north. A large cloud of smoke came from under it. The accused remained seated in the vehicle for a short time. He then opened the driver's door and alighted from the vehicle. He stood alongside the open doorway of his vehicle facing the two police constables as they alighted from the vehicle in which they had been following him. The police officers had their revolvers drawn pointed in his direction. One of the police officers yelled at him to put his hands up. The accused stood there looking at the two constables not moving. He then leaned back into his vehicle across the front seat before standing back up again holding the rifle he had used at the service station. He was holding it in his left hand. The accused held the rifle so that it was pointing forward at an angle of 45 degrees to the ground. He turned and walked away from the police vehicle in a northerly direction. Constable Conway spoke to the accused. I am satisfied that what then happened was as described by Constable Conway (see paras. 188-194 of my reasons for judgment dated 1 April 2003).
[24]
4. I am satisfied that when the accused went into the service station at about 4.00 pm on 20 February 2001 he had not formulated a plan to commit an armed robbery to provoke a confrontation with police and get shot. I am satisfied that he had then formulated a plan to commit an armed robbery and that that was partly as a result of stress of the type which is consistent with his borderline personality disorder as diagnosed by all medical witnesses who gave evidence before me on the trial of the accused's mental competence. I am satisfied that the accused thought in terms of doing an armed robbery to relieve his stress and to relieve stress on those close to him.
[25]
5. I am satisfied that it was only when his ute could go no further that he stopped. It was only then that he thought of confronting and did confront police by using the rifle which he took from his ute after he had alighted from it and stood motionless by his vehicle looking at police as they alighted from their vehicle with revolvers drawn yelling at him to put his hands up.
[26]
6. I am satisfied beyond reasonable doubt that the accused was not intending to drive back to the BP Service Station when he saw police following him as he travelled north towards Tanunda. I am satisfied that had his vehicle not broken down and stopped he would have continued driving to avoid apprehension by the police. I am satisfied beyond reasonable doubt that when he took the money from the service station he intended to keep it for himself. I do not consider that it is a reasonable possibility that he intended to return it to the owner. His evidence was not to that effect.
[27]
On the basis of these findings and the facts and circumstances referred to in my conclusions to my reasons of 1 April 2003 (paras 301-358) I am satisfied beyond reasonable doubt that when the accused demanded and took money from the console operator of the BP Service Station at Munno Para and when he shortly thereafter transferred that money into his wallet and pockets he intended to deprive the owner of that money permanently.
[28]
I am satisfied beyond reasonable doubt that at the time that he took the money from the BP Service Station the accused had an intention to assume ownership of the money, to deprive the owner of the money permanently of it, and to deprive the owner of the money of property in it. I am satisfied beyond reasonable doubt that the accused had an intention to appropriate the money to himself. I am satisfied beyond reasonable doubt that the accused had no intention later to restore the money or any of it to its owner.
[29]
I do not consider that there is a reasonable possibility that the accused had no intention to deprive the owner of the money permanently.
[30]
Accordingly, I am satisfied beyond reasonable doubt that at the time that the accused took the money from the BP Service Station on the afternoon of 20 February 2001 he had an intention to use the rifle to facilitate the taking of the money by him from the scene, and an intention to permanently deprive the owner of it.
[31]
Accordingly, I am satisfied beyond reasonable doubt that, at the time of the events at the service station on 20 February 2001, the accused possessed the necessary subjective elements to commit an armed robbery.
