Conspiracy (criminal)

In criminal law, a conspiracy is an agreement between two or more persons to commit a crime at some time in the future.[1] Criminal law in some countries or for some conspiracies may require that at least one overt act be undertaken in furtherance of that agreement, to constitute an offense. There is no limit on the number participating in the conspiracy and, in most countries, no requirement that any steps have been taken to put the plan into effect (compare attempts which require proximity to the full offense). For the purposes of concurrence, the actus reus is a continuing one and parties may join the plot later and incur joint liability and conspiracy can be charged where the co-conspirators have been acquitted or cannot be traced. Finally, repentance by one or more parties does not affect liability (unless, in some cases, it occurs before the parties have committed overt acts) but may reduce their sentence.

England and Wales

Common law offence

At common law, the crime of conspiracy was capable of infinite growth, able to accommodate any new situation and to criminalize it if the level of threat to society was sufficiently great. The courts were therefore acting in the role of the legislature to create new offences and, following the Law Commission Report No. 76 on Conspiracy and Criminal Law Reform,[2] the Criminal Law Act 1977 produced a statutory offence and abolished all the common law varieties of conspiracy, except two: that of conspiracy to defraud, and that of conspiracy to corrupt public morals or to outrage public decency.

Conspiracy to defraud

Section 5(2) of the Criminal Law Act 1977 preserved the common law offence of conspiracy to defraud.[3]

Conspiracy to defraud was defined in Scott v Commissioner of Police of the Metropolis per Viscount Dilhorne:[4]

"to defraud" ordinarily means … to deprive a person dishonestly of something which is his or of something to which he is or would or might but for the perpetration of the fraud be entitled.

....an agreement by two or more [persons] by dishonesty to deprive a person of something which is his or to which he is or would be or might be entitled [or] an agreement by two or more by dishonesty to injure some proprietary right of his suffices to constitute the offence....

Conspiracy to corrupt public morals or to outrage public decency

Section 5(3) Criminal Law Act 1977[5] preserved the common law offence of conspiracy to corrupt public morals or of conspiracy to outrage public decency.

Conspiracy to corrupt public morals is an offence under the common law of England and Wales.[6]

Conspiracy to outrage public decency is an offence under the common law of England and Wales.[7]

Section 5(1) of the Criminal Law Act 1977 does not affect the common law offence of conspiracy if, and in so far as, it can be committed by entering into an agreement to engage in conduct which tends to corrupt public morals, or which outrages public decency, but which does not amount to or involve the commission of an offence if carried out by a single person otherwise than in pursuance of an agreement.[8]

One authority maintains that conspiracy to "corrupt public morals" has no definitive case law, that it is unknown whether or not it is a substantive offence, and that it is unlikely that conspirators will be prosecuted for this offence.[9]

These two offences cover situations where, for example, a publisher encourages immoral behavior through explicit content in a magazine or periodical, as in the 1970 case of Knuller (Publishing, Printing and Promotions) Ltd v Director of Public Prosecutions, which ultimately was decided in 1973 by the House of Lords.

In the 1991 case of R v Rowley,[10] the defendant left notes in public places over a period of three weeks offering money and presents to boys with the intention of luring them for immoral purposes, but there was nothing lewd, obscene or disgusting in the notes, nor were they printed by a newsmagazine at the behest of Rowley, which would have invoked the element of conspiracy. The judge ruled that the jury was entitled to look at the purpose behind the notes in deciding whether they were lewd or disgusting. On appeal against conviction, it was held that an act outraging public decency required a deliberate act which was in itself lewd, obscene or disgusting, so Rowley’s motive in leaving the notes was irrelevant and, since there was nothing in the notes themselves capable of outraging public decency, the conviction was quashed.

Statutory offence

This offence was created as a result of the Law Commission's recommendations in their Report, Conspiracy and Criminal Law Reform, 1976, Law Com No 76. This was part of the Commission's programme of codification of the criminal law. The eventual aim was to abolish all the remaining common law offences and replace them, where appropriate, with offences precisely defined by statute. The common law offences were seen as unacceptably vague and open to development by the courts in ways which might offend the principle of certainty. There was an additional problem that it could be a criminal conspiracy at common law to engage in conduct which was not in itself a criminal offence: see Law Com No 76, para 1.7. This was a major mischief at which the 1977 Act was aimed,[citation needed] although it retained the convenient concept of a common law conspiracy to defraud: see Law Com No 76, paras 1.9 and 1.16. Henceforward, according to the Law Commission, it would only be an offence to agree to engage in a course of conduct which was itself a criminal offence.

Section 1(1) of the Criminal Law Act 1977 provides:

if a person agrees with any other person or persons that a course of conduct shall be pursued which, if the agreement is carried out in accordance with their intentions, either -

(a) will necessarily amount to or involve the commission of any offence or offences by one or more of the parties to the agreement, or (b) would do so but for the existence of facts which render the commission of the offence or any of the offences impossible, [added by S.5 Criminal Attempts Act 1981] he is guilty of conspiracy to commit the offence or offences in question.

Section 1A (inserted by the Criminal Justice (Terrorism and Conspiracy) Act 1998, s5) bans conspiracies part of which occurred in England and Wales to commit an act or the happening of some other event outside the United Kingdom which constitutes an offence under the law in force in that country or territory. Many conditions apply including that prosecutions need consent from the Attorney General.

Exceptions

  • Under section 2(1) the intended victim of the offence can not be guilty of conspiracy.
  • Under section 2(2) there can be no conspiracy where the only other person(s) to the agreement are:
    1. a spouse or civil partner;[11]
    2. a person under the age of criminal responsibility; or
    3. an intended victim of that offence.

Mens rea

There must be an agreement between two or more persons. The mens rea of conspiracy is a separate issue from the mens rea required of the substantive crime.

Lord Bridge in R v Anderson - quoted in R v Hussain said:[12]

an essential ingredient in the crime of conspiring to commit a specific offence or offences under section 1(1) of the Act of 1977 is that the accused should agree that a course of conduct be pursued which he knows must involve the commission by one or more of the parties to the agreement of that offence or those offences.

Lord Bridge in R v Anderson also said:

But, beyond the mere fact of agreement, the necessary mens rea of the crime is, in my opinion, established if, and only if, it is shown that the accused, when he entered into the agreement, intended to play some part in the agreed course of conduct in furtherance of the criminal purpose which the agreed course of action was intended to achieve. Nothing less will suffice; nothing more is required.

It is not therefore necessary for any action to be taken in furtherance of the criminal purpose in order for a conspiracy offence to have been committed. This distinguishes a conspiracy from an attempt (which necessarily does involve a person doing an act) see Criminal Attempts Act 1981.

Things said or done by one conspirator

Lord Steyn in R v Hayter said:[13]

The rule about confessions is subject to exceptions. Keane, The Modern Law of Evidence 5th ed., (2000) p 385–386, explains:

In two exceptional situations, a confession may be admitted not only as evidence against its maker but also as evidence against a co-accused implicated thereby. The first is where the co-accused by his words or conduct accepts the truth of the statement so as to make all or part of it a confession statement of his own. The second exception, which is perhaps best understood in terms of implied agency, applies in the case of conspiracy: statements (or acts) of one conspirator which the jury is satisfied were said (or done) in the execution or furtherance of the common design are admissible in evidence against another conspirator, even though he was not present at the time, to prove the nature and scope of the conspiracy, provided that there is some independent evidence to show the existence of the conspiracy and that the other conspirator was a party to it.

History

According to Edward Coke, conspiracy was originally a statutory remedy against false accusation and prosecution by "a consultation and agreement between two or more to appeal or indict an innocent man falsely and maliciously of felony, whom they cause to be indicted and appealed; and afterward the party is lawfully acquitted".[14] In Poulterer's Case, 77 Eng. Rep. 813 (K.B. 1611), the court reasoned that the thrust of the crime was the confederating of two or more, and dropped the requirement that an actual indictment of an innocent take place, whereby precedent was set that conspiracy only need involve an attempted crime, and that the agreement was the act, which enabled subsequent holdings against an agreement to commit any crime, not just that originally proscribed.[14]

Conspiracy to trespass

Here, nine students, who were nationals of Sierra Leone, appealed their convictions for conspiracy to trespass, and unlawful assembly. These persons, together with others who did not appeal, conspired to occupy the London premises of the High Commissioner for Sierra Leone in order to publicize grievances against the government of that country. Upon their arrival at the Commission, they threatened the caretaker with an imitation firearm and locked him in a reception room with ten other members of the staff. The students then held a press conference on the telephone, but the caretaker was able to contact the police, who arrived, released the prisoners, and arrested the accused. In this case the Court felt that the public interest was clearly involved because of the statutory duty of the British Government to protect diplomatic premises. Lauton J. delivered the judgment of the Court of Appeal dismissing the appeal from conviction.[15] See Kamara v Director of Public Prosecutions.[16]

Conspiracy to corrupt public morals and conspiracy to outrage public decency

These offences were at one time tied up with prostitution and homosexual behaviour. After the Second World War, due to the fame of several convicts, the Wolfenden report was commissioned by government, and was published in 1957. Thereupon came the publication of several books, both pro and contra the report. Of these books we can isolate two representatives: Lord Devlin wrote in favour of societal norms, or morals, while H. L. A. Hart wrote that the state could ill-regulate private conduct. In May 1965, Devlin is reported to have conceded defeat.[17]

The Street Offences Act 1959 prohibited England's prostitutes from soliciting in the streets. One Shaw published a booklet containing prostitutes' names and addresses; each woman listed had paid Shaw for her advertisement. A 1962 majority in the House of Lords not only found the appellant guilty of a statutory offence (living on the earnings of prostitution), but also of the "common law misdemeanour of conspiracy to corrupt public morals".[18]

In the case of Knuller (Publishing, Printing and Promotions) Ltd v. D.P.P. which was decided 1973 in the House of Lords,[19] the appellants were directors of a company which published a fortnightly magazine. On an inside page under a column headed "Males" advertisements were inserted inviting readers to meet the advertisers for the purpose of homosexual practices. The appellants were convicted on counts of

  1. conspiracy to corrupt public morals, and
  2. conspiracy to outrage public decency.

The appeal on count 1 was dismissed, while the appeal on count 2 was allowed because in the present case there had been a misdirection in relation to the meaning of "decency" and the offence of "outrage". The list of cases consulted in the ratio decidendi is lengthy, and the case of Shaw v. D.P.P.[18] is a topic of furious discussion.

Conspiracy to effect a public mischief

In Withers v Director of Public Prosecutions,[20] which reached the House of Lords in 1974, it was unanimously held that conspiracy to effect a public mischief was not a separate and distinct class of criminal conspiracy. This overruled earlier decisions to the contrary effect. The Law Commission published a consultation paper on this subject in 1975.[21]

Conspiracy to murder

The offence of conspiracy to murder was created in statutory law by section 4 of the Offences Against the Person Act 1861.
