Theft and robbery

Theft is defined in s 1(1) of the Theft Act 1968: "A person is guilty of theft if he dishonestly appropriates property belonging to another with the intention of permanently depriving the other of it." This definition contains five elements, three concerning the actus reus (appropriation, property, belonging to another) and two comprising the mens rea (dishonesty, intention permanently to deprive). The offence is punishable on indictment by up to seven years' imprisonment.

The structure of the Act is deceptively simple. Section 1 sets out the core offence; ss 2–6 elaborate each element in turn. Yet decades of appellate litigation have revealed latent tensions: whether appropriation can occur with the owner's consent (Lawrence, Gomez); what kinds of intangible rights count as property; when a finder or bona fide purchaser has the necessary dishonesty; and the scope of the notoriously complex s 6 (which purports to clarify the intention permanently to deprive).

Robbery, governed by s 8, is an aggravated form of theft: it requires completed theft plus the use or threat of force immediately before or at the time of stealing, in order to steal. Because robbery incorporates theft as a precondition, all five elements of s 1 must be made out; the force element is an additional factual and legal requirement. Robbery carries a maximum sentence of life imprisonment, reflecting its gravity and the public-order concerns it raises.

This note examines each element in turn, surveying the leading authorities, exploring doctrinal controversies over appropriation and dishonesty, and situating the statutory regime within broader debates about criminalisation and labelling in the law of property offences.

The Theft Act 1968 replaced the complex patchwork of larceny, embezzlement, and fraudulent conversion inherited from the common law and consolidated in the Larceny Act 1916. The common law's technical distinctions—between taking and carrying away (asportation), between larceny by a trick and obtaining by false pretences, between custody and possession—had produced a labyrinthine jurisprudence that was inaccessible to juries and difficult to apply consistently. The impetus for reform came from the Eighth Report of the Criminal Law Revision Committee (CLRC), published in 1966, which sought a simpler, more flexible definition.

The CLRC proposed the broad concept of "appropriation" to capture all forms of wrongful dealing, whether by taking, disposing of, consuming, or exercising any right of an owner. The concept of "belonging to another" was extended to include property held on trust, property received under an obligation, and property got by another's mistake. Mens rea was rationalised around the twin concepts of dishonesty and intention permanently to deprive, dispensing with the old law's elaborate distinctions between animus furandi and fraudulent intent.

The 1968 Act represented a high-water mark of statutory codification in English criminal law. But its drafting, while more accessible than the old law, proved ambiguous in key respects. The House of Lords has repeatedly grappled with the meaning of "appropriation," first restricting it to unauthorised acts (Morris), then reversing course to allow appropriation even with consent (Gomez, Hinks). Dishonesty, left undefined in 1968, was eventually given a quasi-objective test by the courts (Ghosh), though that test has now been replaced by a simpler standard following Ivey and Barton & Booth.

Robbery has deeper common-law roots. It was one of the oldest and most serious felonies, originally punishable by death. The 1968 Act preserved the offence, codifying it in s 8 with a straightforward requirement of theft plus force. The emphasis shifted from protecting the King's peace (the common law's concern) to safeguarding personal security and autonomy in the context of property crime.

I. The five elements of theft

Theft requires proof of:

1. Appropriation (s 3): any assumption of the rights of an owner.
2. Property (s 4): money and all other property, real or personal, including things in action and other intangible property; land and certain wild creatures are excluded.
3. Belonging to another (s 5): property belongs to any person having possession, control, a proprietary right, or an equitable interest; includes trust property, property received under an obligation, and property got by mistake.
4. Dishonesty: a question for the fact-finder applying the Ivey test (would the conduct be regarded as dishonest by the standards of ordinary decent people, and did the defendant realise this?).
5. Intention permanently to deprive (s 6): an intention to treat the property as one's own to dispose of regardless of the other's rights; borrowing is insufficient unless the borrowing is for a period and in circumstances making it equivalent to an outright taking.

*II. Appropriation: the ascendancy of Gomez and Hinks***

Section 3(1) provides that "any assumption by a person of the rights of an owner amounts to an appropriation." The House of Lords initially held that there could be no appropriation if the owner consented to the defendant's acts (Lawrence (1971), ambiguous dicta). In Morris [1984] AC 320, Lord Roskill adopted a narrow reading, holding that appropriation required an "adverse interference" or unauthorised act; a shop assistant who switched price labels appropriated, but a shopper who paid at the checkout with the owner's consent did not.

Morris was overruled in R v Gomez [1993] AC 442. D, a shop assistant, induced his manager to accept stolen cheques in payment for goods. The House of Lords held that even an act done with the owner's consent could constitute appropriation; all that mattered was whether D assumed a right of the owner. Lord Keith, giving the leading speech, emphasised that consent was relevant only to dishonesty, not to appropriation. The decision broadened theft dramatically, encompassing what had traditionally been the domain of deception offences.

*I. R v Lawrence [1972] AC 626*

D, a taxi driver, took £6 from an Italian student who spoke little English for a journey worth a few shillings. The student had opened his wallet and invited D to help himself. The House of Lords held that appropriation could occur even where the owner consented to the taking. Viscount Dilhorne's speech stated that the question was whether D had assumed the rights of an owner; consent went to dishonesty, not appropriation. The decision was ambiguous, however, and lower courts continued to debate whether consent precluded appropriation.

*II. R v Morris [1984] AC 320*

D switched price labels on goods in a supermarket. The House of Lords, per Lord Roskill, held that appropriation required an "adverse interference" with or usurpation of the owner's rights; merely assuming one of the rights of an owner could suffice, but the act must be unauthorised. Lord Roskill appeared to limit Lawrence to its facts, suggesting that consent negated appropriation except in deception cases. Morris's narrow reading dominated for a decade.

*III. R v Gomez [1993] AC 442*

D, an assistant manager, persuaded his manager to accept stolen building society cheques in exchange for goods. The manager consented to the transaction. The House of Lords, overruling Morris, held that appropriation does not require absence of consent. Lord Keith approved Lawrence and held that s 3(1)'s phrase "any assumption" is unqualified; consent and authority are relevant to dishonesty, not to appropriation. The decision collapsed the distinction between theft and obtaining by deception, a point Lord Lowry made in dissent.

*IV. R v Hinks [2001] 2 AC 241*

D befriended a man of limited intelligence and received daily gifts of cash totalling some £60,000 over six months. The civil law regarded the gifts as valid (no undue influence or incapacity was proved). The House of Lords held (Lord Steyn, Lord Jauncey, Lord Hutton; Lord Hobhouse and Lord Slynn dissenting) that even an indefeasible gift could be appropriated if obtained dishonestly. The criminal law's concept of appropriation is independent of the civil law's proprietary analysis. Lord Hobhouse's dissent warned that this created intolerable overlap between criminal and civil remedies and punished "bad behaviour" rather than true theft.

*V. R v Ivey [2017] UKSC 67 and R v Barton & Booth [2020] EWCA Crim 575*

Although Ivey concerned cheating at gambling (Gambling Act 2005), the Supreme Court's analysis of dishonesty has been adopted for theft. The Court rejected the second, subjective limb of Ghosh: D's own moral views are irrelevant; the question is whether his conduct, on his understanding of the facts, would be regarded as dishonest by ordinary standards. Barton & Booth confirmed this test applies to the Theft Act 1968. The effect is to remove the defence of "Robin Hood" defendants who believe their conduct morally justified.

*VI. R v Lloyd [1985] QB 829*

D, a cinema projectionist, removed films to allow an accomplice to make pirate copies, then returned the originals. The Court of Appeal quashed the conviction: s 6(1) requires an intention to deprive the owner of the property's "goodness, virtue, or practical value." Temporary use, even if dishonest and unauthorised, is insufficient. The decision has been followed in cases involving concert tickets used and returned, though the borderline between use and exhaustion of value remains uncertain.

*VII. R v Hale (1978) 68 Cr App R 415*

D and E entered V's house; D seized a jewellery box while E tied up V. The Court of Appeal held that appropriation is a continuing act; force applied after the initial seizure but before the thieves left the scene could be "at the time of" stealing for the purposes of robbery. The principle avoids artificial distinctions about the precise moment appropriation is complete and reflects the reality of robbery as a single course of conduct.

*VIII. DPP v Gomez (on robbery) and R v Robinson [1977] Crim LR 173*

In Robinson, D, owed money, threatened V with a knife and took cash. The Court of Appeal held that if D genuinely believed he had a legal right to the money, he lacked dishonesty and therefore could not commit theft or robbery, even if his means of recovery were criminal (assault). This principle, rooted in s 2(1)(a), remains good law but is narrowly applied: the belief in a right to the property must be honestly held and must relate to a legal (not merely moral) entitlement.
