Revise Theft as defined in s1 Theft Act 1968 for Cambridge 9084 (2.2.1)

The modern law of theft is contained within the Theft Act 1968 (TA 1968). Section 1(1) provides the definitive statement: '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 single sentence contains all five elements that the prosecution must prove beyond reasonable doubt for a conviction. These elements are broken down into the actus reus (the guilty act) and the mens rea (the guilty mind). The actus reus consists of three parts: appropriation (s3), of property (s4), belonging to another (s5). The mens rea consists of two parts: dishonesty (s2) and an intention to permanently deprive (s6). Each element has been interpreted and developed through subsequent case law.

Appropriation is defined in s3(1) as 'any assumption by a person of the rights of an owner'. This is a very wide concept. R v Morris established that assuming any single right of the owner, such as changing a price label, is sufficient. A major development came in Lawrence v MPC, confirmed in R v Gomez, which held that an appropriation can occur even with the owner's consent. This means a shop assistant who dishonestly persuades a customer to accept fake currency is appropriating the goods sold. The principle was taken to its logical extreme in R v Hinks, where the House of Lords held that accepting a valid gift from a vulnerable person could amount to an appropriation if it was done dishonestly. This highlights that appropriation is a neutral act; its criminality depends on the accompanying mens rea. Section 3(1) also covers a 'later appropriation', where a person comes by property innocently but later decides to keep it and treats it as their own. The appropriation happens at the point of that later decision. Furthermore, s3(2) provides a key exception for a bona fide purchaser: a person who buys goods in good faith for value does not commit theft, even if the seller did not have the right to sell them.

The final two actus reus elements define what can be stolen and from whom. Section 4 defines 'property' very broadly to include money, real property (land), personal property, things in action (e.g., a bank account balance), and other intangible property (e.g., a patent). However, confidential information is not property (Oxford v Moss). While the definition is wide, there are specific statutory limitations. Section 4(2) states that land cannot be stolen, except in three specific circumstances: by a trustee, by someone not in possession severing something from the land, or by a tenant taking a fixture. Section 4(4) provides that wild creatures cannot be stolen unless they have been tamed, are ordinarily kept in captivity, or have been reduced into possession.

Section 5 defines 'belonging to another' as any person having possession or control of it, or having any proprietary right or interest. This is wider than simple ownership. A person can therefore be guilty of stealing their own property if it is in the possession or control of another, as seen in R v Turner (No 2). Section 5(3) applies where a person receives property and is under a legal obligation to deal with it in a particular way. If they use it for a different purpose, it can be theft, as in Davidge v Bunnett where a flatmate used bill money for shopping. Section 5(4) creates liability where property is received by mistake and there is an obligation to make restoration, as confirmed in A-G's Ref (No 1 of 1983) regarding overpaid wages.

Dishonesty is the primary mens rea element, but the Act does not define it. Instead, s2(1) gives three situations in which a person's appropriation is not dishonest: if they believe they have a right in law, believe the owner would consent, or believe the owner cannot be discovered by taking reasonable steps. If none of these apply, the common law test must be used. The long-standing two-part test from R v Ghosh was overruled by the Supreme Court in Ivey v Genting Casinos (2017). The current test is a single, objective one: 1) What was the defendant’s actual state of knowledge or belief as to the facts? 2) Based on that knowledge/belief, was their conduct dishonest by the standards of ordinary, decent people? The defendant's own belief about the dishonesty of their actions is no longer relevant.

The second mens rea element requires the defendant to have an 'intention of permanently depriving the other of it'. This is an ulterior intent – the deprivation does not actually have to happen, only be intended. In most cases, the ordinary meaning is sufficient. However, s6(1) extends the definition to cover complex situations. It states that a person has the necessary intention if they treat the property as their own 'to dispose of regardless of the other's rights'. This covers cases like R v Lavender, where the defendant took doors from a council property and put them on another. It also covers borrowing 'for a period and in circumstances making it equivalent to an outright taking', such as where the 'goodness, virtue and practical value' has gone from the item upon its return (R v Lloyd). The principle also extends to 'ransom' cases. If a person takes property and will only return it upon a payment, this is treated as an intention to permanently deprive because they are treating the property as their own to dispose of (R v Raphael).
