Conspiracy to defraud
 England and Wales
it is clearly the law that an agreement by two or more by dishonesty to deprive a person of something which is his or to which he is or would be entitled and an agreement by two or more by dishonesty to injure some proprietary right of his, suffices to constitute the offence of conspiracy to defraud.
Conspiracy to defraud therefore contains two key elements; that the conspiracy involved dishonesty, and that if the conspiracy was undertaken, the victim's property rights would be harmed. This does not require the defendants' actions to directly result in the fraud; in R v Hollinshead, the House of Lords held that producing devices designed to alter electricity meter readings constituted conspiracy to defraud, even though the actual fraud would be carried out by members of the public rather than the conspirators. In two situations, it will not even be necessary for the actions to directly lead to any kind of financial loss for the victim; these are when the conspirators plan to deceive a person holding public office into acting counter to their duties, and when the conspirators know that their actions put the victim's property at risk, even if the risk never materialises.
The following cases are also relevant to this offence:
- R v Orbell (1703) 6 Mod Rep 42, (1703) 12 Mod Rep 499
- R v Button (1848) 11 QB 929, (1848) 18 LJMC 19, (1848) 12 LT (OS) 309, (1848) 13 JP 20, (1848) 12 Jur 1017, (1848) 3 Cox 229
- R v Yates (1853) 6 Cox 441
- R v De Kromme (1892) 66 LT 301, (1892) 56 JP 683, (1892) 8 TLR 325, (1892) 17 Cox 492
- R v Quinn (1898) 19 Cox 78
- R v Boyle and Mears, 94 Cr App R 158, CA
Although most frauds are crimes, it is irrelevant for these purposes whether the agreement would amount to a crime if carried out. If the victim has suffered of any financial or other prejudice there of, there is no need to establish that the defendant deceived him or her. But, following Scott v Metropolitan Police Commissioner (1974) 3 All ER 1032, it is necessary to prove that the victim was dishonestly deceived by one or more of the parties to the agreement into running an economic risk that he or she would not otherwise have run, if the victim has not suffered any loss. For the mens rea, it is necessary to prove that "the purpose of the conspirators (was) to cause the victim economic loss" (per Lord Diplock in Scott). For the test of dishonesty, see R v Ghosh (1982) 2 All ER 689.
 Relationship to statutory conspiracy etc
Section 12(1) of the Criminal Justice Act 1987 provides that:
the fact that it will do so shall not preclude a charge of conspiracy to defraud being brought against any of them in respect of the agreement.
- (a) a person agrees with any other person or persons that a course of conduct shall be pursued; and
- (b) that course of conduct will necessarily amount to or involve the commission of any offence or offences by one or more of the parties to the agreement if the agreement is carried out in accordance with their intentions,
Paragraphs (a) and (b) are derived from section 1(1) of the Criminal Law Act 1977 and refer to the offence that that section creates.
As to section 12, see R v Rimmington, R v Goldstein  UKHL 63.
Before 20 July 1987, section 1 of the Criminal Law Act 1977 did not apply in any case where the agreement in question amounted to a conspiracy to defraud at common law.
 Incitement to conspire
