Theft and robbery

Theft is the central offence of property criminality in English law. Its statutory formula in s 1(1) of the Theft Act 1968 is deceptively short: dishonest appropriation of property belonging to another with the intention permanently to deprive. Each element is independently significant, and each has generated difficult litigation. The offence is not merely an aggravated form of civil conversion. Nor is it a general offence of moral sharp practice. It is a criminal offence which attaches penal consequences to certain forms of dealing with another’s property, but it does so through concepts — property, rights, obligation, consent, ownership, mistake — which are partly drawn from private law and partly reshaped for criminal purposes.

For Cambridge Part IA, theft is usually examined in two forms. First, there are problem questions. These require disciplined element-by-element analysis: was there property; did it belong to another; was there an appropriation; was D dishonest; did D intend permanently to deprive? Secondly, there are essay questions about the coherence of the law, especially after R v Gomez, R v Hinks, Ivey v Genting Casinos, and Barton and Booth. These ask whether theft has become too broad, whether dishonesty is an adequate limiting concept, and whether the criminal law has become over-dependent on lay moral judgment.

Robbery, under s 8 Theft Act 1968, is theft plus violence or threatened violence used immediately before or at the time of stealing and in order to steal. The offence is therefore parasitic on theft: if there is no theft, there is no robbery. Yet robbery is not merely theft accompanied by force. The force must have the required temporal and purposive connection with the stealing. Cases such as Hale, Lockley, Dawson and James, and Clouden show the breadth of these requirements. In exam terms, robbery is often where candidates lose marks by assuming that any violent incident accompanying a taking suffices. It does not: one must ask when the theft was complete, whether appropriation was continuing, whether force was used on any person, and whether it was used in order to steal.

The dominant theme is breadth. Appropriation may occur despite the owner’s consent. A valid gift may constitute appropriation. Property may belong to another although D has possession, control, or even civil title subject to an obligation. Intention permanently to deprive may be found where D does not literally intend permanent loss of the physical object, provided D treats the property as his own to dispose of regardless of the other’s rights. Dishonesty is the principal normative filter. After Ivey, that filter is objective once D’s actual knowledge or belief as to facts has been ascertained. The old second limb of Ghosh — whether D realised ordinary honest people would regard his conduct as dishonest — is gone.

A strong supervision answer therefore resists both over-criminalisation panic and doctrinal complacency. The Theft Act deliberately replaced technical larceny with broad statutory language. But breadth creates pressure elsewhere. If appropriation is virtually any assumption of ownership rights, and consent is no answer, the line between civil invalidity, exploitation, breach of trust, and theft must be policed mainly by dishonesty and by the requirement of intention permanently to deprive. The best answers show how these elements interact rather than treating them as isolated boxes.

The Theft Act 1968 was enacted to replace the fragmented common law and statutory offences of larceny, embezzlement, fraudulent conversion, obtaining by false pretences, and related property offences. The old law was notoriously technical. It distinguished between taking possession from another, receiving possession lawfully but later misusing it, obtaining title by deception, and handling property after the event. Much turned on highly artificial distinctions between possession and ownership. The Criminal Law Revision Committee sought to rationalise this field by creating a general offence of theft framed in broad conceptual terms.

The 1968 Act therefore marks a deliberate movement away from the old law of larceny. Larceny required a trespassory taking and carrying away of another’s personal goods with intent permanently to deprive. It was ill-suited to modern commercial and fiduciary contexts. Embezzlement and fraudulent conversion filled some gaps, but the resulting law was technical and uneven. The new offence of theft was designed to be wider and simpler. It substituted appropriation for taking, property for goods, belonging to another for narrow ownership, and dishonesty for more elaborate forms of fraudulence.

That simplification came at a price. The statutory language is broad enough to cover conduct far removed from the paradigm of stealing a wallet. This is especially true of three elements. First, appropriation is defined by s 3 as any assumption of the rights of an owner. The House of Lords in Gomez confirmed that appropriation can occur with the owner’s consent. Hinks then held that a valid gift may be an appropriation. Secondly, property belonging to another is defined by s 5 to include possession, control, proprietary interests, trusts, and certain obligations to retain and deal with property in a particular way. Thirdly, dishonesty was not exhaustively defined in the Act. Section 2 gives situations in which appropriation is not dishonest, but leaves the general meaning to the courts.

The history of dishonesty is especially important. For decades the leading test was R v Ghosh. The jury asked whether D’s conduct was dishonest by the standards of ordinary decent people and, if so, whether D realised that ordinary decent people would regard it as dishonest. That second, subjective limb was criticised for allowing the morally obtuse defendant to escape liability. Ivey rejected it in the civil context of cheating at gambling, and Barton and Booth confirmed its application in criminal cases. The present approach is to determine D’s actual knowledge or belief as to the facts, then assess dishonesty by the objective standards of ordinary decent people. This is not pure objectivity: factual belief remains subjective. But D need not appreciate that his conduct is dishonest by ordinary standards.

Robbery’s history is different but connected. At common law robbery was larceny from the person by violence or putting in fear. Section 8 Theft Act 1968 restates robbery in terms of theft plus force or fear of force. Because theft is broader than larceny, robbery is correspondingly affected by developments in theft. The notion of a continuing appropriation, especially in Hale and Lockley, gives robbery a wide reach: force used after the initial taking may still be treated as occurring at the time of stealing if the appropriation is continuing.

For Tripos purposes, the historical context matters because it explains why courts have often preferred breadth over technical limitation. The 1968 Act was not intended to preserve larceny under another name. Yet when breadth becomes excessive, courts have usually resisted reintroducing old technicalities and have instead relied on dishonesty, jury judgment, and the intention permanently to deprive. Whether that is satisfactory is the main evaluative question running through this topic.

The actus reus of theft contains three elements: appropriation, property, and belonging to another. The mens rea contains two elements: dishonesty and intention permanently to deprive. These are analytically distinct, but in real cases they overlap. For example, a mistaken belief in a right to take property may be relevant both to dishonesty under s 2(1)(a) and to whether D intended to deprive another of property which D regarded as his own.

Appropriation is defined by s 3(1) as any assumption of the rights of an owner. It is not necessary to assume all ownership rights. Labelling goods with a lower price, selling another’s property, taking it away, destroying it, keeping it, or dealing with it inconsistently with the owner’s rights may suffice. Morris is important because it rejects the need for assumption of every right of ownership. Appropriation can also be continuing where D has come by property innocently but later keeps or deals with it as owner. This matters in robbery, where force used during escape may be treated as force used at the time of stealing.

Consent is no bar to appropriation. Lawrence held that a taxi driver appropriated an Italian student’s money when the student consented to the payment under a misunderstanding. Gomez went further and confirmed that an owner’s valid consent does not prevent appropriation. Hinks went further still: even a valid gift may be an appropriation. The result is conceptually striking. Appropriation is not a wrongful taking; it is a neutral assumption of ownership rights. Wrongfulness is supplied, if at all, by dishonesty and intention permanently to deprive.

Property is broadly defined by s 4. It includes money, real and personal property, things in action, and other intangible property. However, confidential information itself is not property for theft, as Oxford v Moss illustrates. Land is treated exceptionally: it generally cannot be stolen except in the statutory cases in s 4(2). Wild plants, mushrooms, and wild creatures are also subject to special rules. The breadth of property is important in commercial settings: bank balances, debts, and choses in action may be property, but the analysis must identify the precise property said to have been appropriated.

The modern law of theft is largely a story of expansion, followed by reliance on dishonesty as a limiting device. Lawrence v Metropolitan Police Commissioner first made clear that consent does not prevent appropriation. The victim, an Italian student unfamiliar with English currency, allowed a taxi driver to take excessive money. The House of Lords treated the driver’s conduct as appropriation notwithstanding the victim’s apparent consent. The significance of Lawrence is not merely factual; it separates appropriation from trespass. Appropriation is not defined by absence of consent.

Morris then considered price-switching in a supermarket. The House of Lords held that assuming one of the rights of an owner was sufficient. It was not necessary to assume all ownership rights. The case is sometimes read narrowly as a price-label case, but its importance is general: appropriation is any significant exercise of ownership rights. Gomez confirmed and extended Lawrence. D procured goods by presenting stolen cheques, with the manager’s consent to the goods leaving the store. The House of Lords held that consent did not prevent appropriation. Gomez made appropriation a neutral concept and moved the burden of normative judgment to dishonesty.

Hinks is the most controversial appropriation case. The defendant received gifts from a man of limited intelligence. The gifts were valid in civil law. The House of Lords nevertheless held that a valid gift can amount to appropriation for theft. This is doctrinally coherent if appropriation simply means assumption of ownership rights. But it creates an uneasy overlap between theft, exploitation, undue influence, and civil validity. Hinks makes dishonesty do substantial work.

Turner (No 2) demonstrates the breadth of ‘belonging to another’. D removed his own car from a garage without paying. The car belonged to another because the garage had possession or control. The case is an essential antidote to the common student error that one cannot steal one’s own property. In theft, belonging is broader than ownership.

The treatment of property received subject to obligation is illustrated by Davidge v Bunnett and Wain. In Davidge, money given for payment of bills was treated as belonging to another where D was obliged to apply it in that way. In Wain, charity fundraising proceeds were held to be property belonging to the charity because they had to be retained and dealt with for that purpose. By contrast, Hall shows that a mere contractual obligation or debt will not always suffice. The statutory question under s 5(3) is whether D was under an obligation to retain and deal with the specific property or proceeds in a particular way.

Attorney-General’s Reference (No 1 of 1983) is central to s 5(4). An employee was overpaid and failed to restore the money. The Court of Appeal held that, once she became aware of the mistake, she was under an obligation to restore, and the money belonged to the employer to the extent of that obligation. This provision is especially important in bank transfer and payroll examples.

On intention permanently to deprive, Lloyd and Velumyl show the distinction between temporary deprivation and deprivation of the very property. In Lloyd, borrowing cinema films for a short time and returning them did not necessarily amount to intention permanently to deprive, because the films retained their practical value. In Velumyl, taking company money intending to replace it later with other money was enough: money is treated as specific property for these purposes.

For robbery, Dawson and James and Clouden illustrate the low threshold for force. Hale and Lockley illustrate continuing appropriation. In Hale, force used after jewellery had been taken could still be ‘at the time of stealing’ because appropriation was a continuing act. In Lockley, force against a shopkeeper during escape after taking goods could support robbery. These cases make robbery significantly broader than a simple snapshot of force at the instant of taking.
