a group of defendants resold used tickets for the London Underground. The Court of Appeal dismissed their appeal in part because the tickets said they were the property of London Underground, a condition of sale agreed to by the original buyer of the ticket. Section 5 includes subsections that deal with possession that has conditions. Section 5(3) deals with situations where a person has given property to another for a particular purpose: the person receiving the property is said to be engaging in theft if they use the property for some purpose it was not intended. If A gives B money to purchase a particular good for A and B buys something else with it without A's consent, even though the property is not in A's hands, A still has a controlling interest in it under Section 5(3). If one is placed under a duty to use property in a particular way, that obligation must be legal under civil law according to the Court of Appeal in R v Breaks and Huggan (1998). There are limits to the legal obligations one is liable for under Section 5(3). In R v. Hall (1972), a customer paid a deposit to a travel agent. The deposit was paid into the company's bank account but the travel agent went out of business. This was not an instance of theft as the money was legitimately paid as a deposit against cancellation and there was no specific obligation to spend the money in a particular way. Section 5(4) requires that if property is received by mistake it must be returned and failure to do so counts as appropriation. This was seen in action in Attorney-General's Reference (No. 1 of 1983) where a police officer was given £74 extra in her wages but failed to return it or alert her superiors to it. The Court of Appeal held it to be theft. Section 6 – "Intention to permanently deprive" This section provides that a person in order to be guilty of theft had the intention of permanently depriving the other of the property. In certain cases, the intention to deprive may be construed, even when the person may not have meant to deprive another of their property permanently, for example if the intention is to treat another's property as one's own to dispose of regardless of the other's rights. Section 7 – Theft This section provides that
